Further tweaking & Extra info

..

So, set everything back to highest FSB/multi/voltages etc as found out earlier on, and start tweaking that bandwidth down the list until you find the fastest it'll achieve.

Remember to run a Sandra memory bench after each tweak to burn in the memory as you go and to check the bandwidth. Write your scores down as you go, or better still get a screen-capture and name it something to remind you of what it is etc. Combine all of this lot together to get your system to its MAX. When stability goes flaky, start try dropping the FSB slightly to allow you to raise the bandwidth tweaks, as often better timings will increase your scores better than a higher FSB... Macci once pointed out to me that his memory bandwidth scores at 166Mhz floored mine at 200Mhz, and that's when I learned that the timings were everything for good 3DMarkscores.

You'll find a point where Sandra will run but 3DMark won't. Make the decision, what are you trying to achieve. Is the overclock just so you can have a faster PC, or are you using your overclocking skills to gain you a reputation and earn respect of others? If the answer is the latter, then it's irrelevant. You'll spend one day getting the best CPU Mhz you can. Another day devoted to getting a screencap of the best Mem Bandwidth you can. Another day getting the highest 3DMark score you can, another day getting the fastest HardDrive transfer rates you can.... screencaps of the lot, post 'm in the forums, let the fans worship & adore you (until they beat you!!). Hardcore overclockers spend weeks devoted to bettering each individual score, and then when they've got the best scores they can, they sell off that component and try to find one that'll do even better... On and on we go...



Added note...

Barton CPUs
Get a damn site hotter than Thoroughbred CPUs, and need more voltage to get good overclocks. Average top out on Prometeia / nVentiv Mk II - 2.7Ghz for average stepping. 3Ghz for super stepping. You won't get as high as TOTAL overclock out of a Barton as you would out of (for example) a Thoroughbred 1700+ DLT3C, however, a Barton at 2.4Ghz can match and beat a Thoroughbred at 2.6Ghz... usually....

2500+ is the most popular choice. These hit 2.6/2.7Ghz with about 2.1v on a Prometeia. On water expect to top out at around 2.5Ghz or 2.6Ghz... They'll do 2.3Ghz with ease at 1.9v usually.


Thoroughbred CPUs

Steppings count. Look for CPUs with a DLT3C JIUHB stepping (usually XP1700, 1800 & 1900 CPUs). The 1700+ CPUs can go to 3Ghz if you have a REALLY good one, or 2.8Ghz if you have an average one. These chips run at a lower default voltage, so run cooler, and need less juice to go fast.... so when you give em LOTS of juice, they go REALLY fast! On NF7 boards, these chips tend to top out on voltage... they rarely post at 2v without setting sirens and alarms off, but that's down to the way the board handles power.
Average OC? On air, about 2.4Ghz, on water about 2.6Ghz, on pelts around 2.7Ghz, on Promi about 2.8Ghz.



Memory ratings

Most of you have good memory, but also, a lot of you have it for bragging rights and don't put it to use. If you have anything above PC2700 speeds, and you DON'T have a Barton 3000+ or 3200+, and you're not overclocking, then your ram is merely an attempted willy-extension that works in reverse to those in the know, and actually halfs the size of your willy. :-)


Background - CPU FSBs

Athlon XP Palomino and Thoroughbred CPUs - default FSB 133 (PC2100)
Athlon XP Barton CPUs - default FSB 166 (PC2700) or 200 (PC3200)

So, unless you set your ram to run at its rated speed (thus overclocking the FSB of your CPU usually) then you've forked out for summat pointless... here's what FSB you should be running at...

PC2100 - 133FSB (DDR266)
PC2700 - 166FSB (DDR333)
PC3200 - 200FSB (DDR400 for AMD, QDR800 for INTEL)
PC3500 - 217FSB (DDR433)
PC3700 - 233FSB (DDR466)
PC4000 - 250FSB (DDR500)
PC4200 - 266FSB (DDR533)

Now, anything ABOVE 3500 tends to work out to be a duff buy for AMD users. Once you hit 3700, default rated CAS timings get ridiculously slow - usually Cas3, and as soon as you try to make them faster - Cas2 - you can't achieve rated FSB, let alone overclocked FSB... For AMD users it is much harder to run ultrafast FSBs like the P4 boys do, so we rely more on Ram timings to keep us on their heels.... 3500 and below is generally rated at Cas2 by default, and 9/10 times will tighten up to 11-2-2-2 on an nForce2 board without problems.

Most AMD Boards and processors will struggle to run at 233FSB anyways, therefore 3700 is a bit pointless... and when you DO get it up there, with the slower CAS timings that you'll need you'll find that running at 217FSB with 3500 at a faster CAS Timing actually offers much better performance.

BUYING memory

we've just gone through which is best to buy.... anything at 3500 and below for AMD users. What you want to be looking for is the highest rated speed at the lowest rated CAS Timings.... i.e.: PC3500 rated at 6-3-3-2 is a better buy than PC3500 rated at 7-3-3-2. By dropping the 6-3-3-2 stick's timings to 7-3-3-2, you're practically guaranteeing another 5Mhz on top of rated speeds for that ram. The best stuff to find is ram rated at 5-3-3-2 or 5-2-2-2 at 1T Command. This was around in the days of the KT333 chipset, where there were a lot more options available to you in the bios for tweaking your ram. The nForce2 chipset, with its much more aggressive approach to memory, meant that suppliers had to slow down their CAS ratings to get their memory to work properly with the chipset and its Dual Channel Architecture, hence why we see more and more memory coming onto the market rated at 8-4-4-2.

I have an AMD 855 mhz cpu with a Jabil AMD R4 Motherboard. I was wondering if there is a program able to OC them (my bios does not support it) and their optimal settings.
Comment from jmke @ 2003/11/02
Is this a GateWay PC?
http://support.gateway.com/s/MOTHERB...000646nv.shtml

most OEM computer system have very low support for overclocking through the BIOS (*read: none*)

You could try to look for an older tweak software called "SoftFSB", it is no longer supported or developed, but it supported some older motherboards (VIA KT133), but I'm not sure if it will support yours.
Comment from Unregistered @ 2003/11/02
Yeah it is a Gateway(sux so much). I'm looking into building a new computer(can't wait). Thnx a lot.
Comment from Unregistered @ 2003/11/02
Appartently(and Unfortunately) the "SoftFSB" doesn't support my Jabil motherboard. I'll go on to the next, which is my CPU. I need a program(bios doesn't work) to OC my AMD Thunderbird 850. I've been looking for awhile.
Comment from Unregistered @ 2003/11/02
I have a Barton 2500+ and am a little leery of OC ... although, I guess I'm here, reading.

I don't have a steady source of income, and the consulting I do does rely on this machine. However, my video gaming also relies on this machine, and I'm interested in better performance.

With the factory heatsink from AMD and an array of 6 fans for cooling, what level of danger is there in OCing a bit?

(Need validation ... heh.)
Comment from piotke @ 2003/11/02
just monitor the temperatures. While overclocking, on not too high voltages your CPU should stay under 50┬░ C.

It will work on higher temps, but there is a big possibility for instability

you "could" paint the bridges on your Tbird to give it a higher multiplier, thereby overclocking your CPU without the need of any bios and/or software tool. But there is a much higher risk involved since you need to remove the CPU from the socket, use a carbon pencil to paint over the correct bridges and then hope you didn't make any false contacts.

If this is your only PC, I would NOT recommend this action however.

it is needles to say that cutting bridges on a CPU can destroy it


I suggest to only read this guide:
http://www.ocinside.de/html/workshop...resistors.html

and when eventually you get to buy a new PC, try it out then on the old Tbird
Comment from Unregistered @ 2003/11/02
Thnx jmke you've been a great help, I've also located a good source on what different voltages(some or all with a different heatsink) on my T-Bird 850 will turn out. They did all the work, Overclockers.com is a good source.
Comment from Avalon @ 2003/11/03
This guide shouldn't be called AMD optimal bios settings. It only shows clockspeed/voltages/mem timings settings. There are other important bios options for a succesfull overclock.

The T-bird 850 was my most lousy OC'er.
With VERY LOUD aircooling it only did 950, no matter what i tried. Ain't worth the effort.

what other settings do you suggest?
it is correct that this guide is aimed strongly towards the memory timings only.

these are the other ones I disable for getting the highest overclock
*Video Memory Cache Mode = disabled
*Spread Spectrum = disabled
Comment from Unregistered @ 2003/11/04
with the "agp speed" in the nvidia based program. should this be increased? or kept @ original settings? what does increasing the agp speed actually do / what damage can it cause?

im on a 2500+ @ 2.3ghz ( so far ) i tried 200x12 but it froze after about 10mins. i think ill mess with it latest based on this guide see if i cant push it further. althou i am on stock cooling.

my vid card is a Radeon 9700np

Ta.
Comment from jmke @ 2003/11/04
increasing the AGP speed will have an increase in overall 3D games as effect, but not all cards support higher AGP speeds, the ATI 9700 is pretty sensitive to increased AGP speeds.
Comment from cowbite @ 2003/11/05
Ok, situation isnt really a problem but a hastle.
Specs:
AMD AthlonXP 2200+ with speed-strip unlocking strip installed
1 stick unknown vendor PC 3200 512mb ram
Asus A7N8X-D Motherboard

I determined 169 was the highest FSB I can post with.
169x12.5 = 2112.5

The Nvida System Utility correctly shows the FSB as 338 and from there I can raise the 338 to 352 and it runs GREAT at 2.2 GHZ!!
By this rational, I should be able to set my FSB in the BIOS to 176 (352 div by 2) and have it post successfully....right? Nope. It wont.
I have to reset the bios and start over.

WHY? I can't figure it out.
I can't *boot* at 2.2GHz but I *can* go into windows and raise it to 2.2 GHz and have it run fine.

Any help?
Comment from Gamer @ 2003/11/05
did you do some tests with the tool and without ?
Comment from cowbite @ 2003/11/05
I ran aquamark and 3dmark03 both of which show better scores after the overclocking. I just dont want to have to screw with the nvidia utility every time I reboot. And apparently there are advanced options in the util that are unavailable to me for some reason. My understanding is that the advanced options apply themselves at every boot.
Comment from Unregistered @ 2003/11/21
i have a asus A7V8X is there a program that could easily overclock it, without me going into bios. My friend has a gigabyte mobo and he has a utility like that could i install/use it on this mobo?
Comment from cowbite @ 2003/11/21
-Post Edited-
Sorry, my original post was about the nvidia system util but I didnt realize the mobo you were talking about was a KT400 chipset board :\
Comment from Unregistered @ 2003/11/27
sir could i have your advice on why can't i tweak my multipilier, if i change it even at .5 my system won't post, is there something i'm missing?

Comment from cowbite @ 2003/11/27
Your CPU is multiplier locked. Meaning, you cannot change multiplier, only the front side bus (FSB). There are methods of unlocking CPUS - some that are easy and some that put your cpu in serious peril if you mess up. I used the easiest and safest route and bought a speed-strip from www.speed-strip.com (actually I bought it somewhere else).
Review here : http://www.overclockercafe.com/Revie...c/Speed-Strip/

Provided your CPU's ID starts with "AXDA" (see website or review site) then you can use it. You just put it under the CPU as per instructed and it unlocks it. Then you can set your FSB as you like.
Comment from Tum0r @ 2003/11/27
Is there a way so I can put 2 shortcuts on my sektop that will set my rig on low speed (downloading or surfing) or high (gaming ...) without having to go in nvdia system ultility and moving the slider along?

but at the same time changed the vcore (what I cant do with nvidia system utility but with 8rdaVcore)

Is this with reg files or? I dont hav a clue how these progs change what they change
Comment from jmke @ 2003/11/27
get clockgen!
http://www.cpuid.com/clockgen.php

now support nForce2 chipsets, it allows you to make shortcuts to overclock to a certain,

you'd still need to manually adjust the vcore though :/
Comment from Tum0r @ 2003/11/27
I'le do just that



ps. A good tweaked winXp pro should use xxx amount of ram? About 125mb is ok or can u do whole lot better?

I'm inpressed that clockgen can change with less than 1mhz but doesnt hav an advantage over nvidia system utitlity as I still hav to open clockgen and then load the saved config (same as Nsu)

Nsu can change the ram setting to and clockgen cant...

I was hoping to get shotcuts (hihg and low settings) on my desktop

I just noticed the pci goes up together with my agp speed
Thats not right?
Comment from Unregistered @ 2003/11/28
Hey i was wondering if there is any way to over clock my Compaq
Specs
AMD 2400 xp @1995
Unkown mem came with the rig (512mb)
80 gig hardrive(i know that this really does not apply to the OC accievable)
Compaq mobo
I have a duct to the cpu fan and 3 extra case fans i can keep the temp in the case about 2-3 degrees above room temp while playing UT 2k1 at all of the highest possible settings
Nvidia Quadro 750xgl
Could i flash it with a bios from another board by any chance i can overclock the Quadro with a tweak to change the mem and core speed. but not the voltage.
So is there any way to get an overclock out of this setup any help would be greatly apreciated thaxs to all that will help
Comment from Tum0r @ 2003/11/28
clockgen or better yet nvidia system ultility would work for u

about the unknown ram: dl aida wich can id the ram pc2700 or higher will be most likely

u can also find a very usefull guide here @[M!
Comment from jmke @ 2003/11/28
Compaq motherboard.. compaq usually uses their own layout, bios and software, meaning that tweaking/overclocking on these PC's is most likely impossible :/
Comment from Unregistered @ 2003/11/29
srry the last post i made was about the compaq OC and it is not 2K1 it is 2K3 unreal tournemnet
Comment from Unregistered @ 2003/11/29
well is there any way that i could flash the bios to say abit or something like that i am gettin gnew stuff for x-mass

Thermaltake Xaser III case
Corsair Pro Series 512MB PC3200 DDR 400MHz Memory
AMD Barton 2500+
Danger Den RBX water block
Soyo Dragon KT 600 chip set
Radeon 9800XT 126

If i get this what do u think my benchmarks will be
if i over clock the barton to say 2.5 i also might get a 256 watt pelteir so then i will have some major cooling

thanks to all that will post o and i am still wondering about any way to OC my compag that i have now. thanxs to the ppl that have already posted about this
Comment from Unregistered @ 2003/11/30
i would think that u could if u found a bios of around the same size and supported the same stuff. It should be doable but it would be risky beacuse u might fry ur mobo or worse
DO IT AT UR OWN RISK
Comment from jmke @ 2003/11/30
I would not flash a motherboard with a bios that is not intended for it, the risk of ending up with a dead motherboard is very high
Comment from Tum0r @ 2003/12/03
http://www.hasw.net/8rdavcore/

new version is out so hav fun
AutoFSB:


--------------------------------------------------------------------------------

AutoFSB automatically sets the FSB depending on the CPU load. First you must know your min. and
max. FSB, set them with the FSB trackbar and the Max. and Min. buttons. You also should set some
VCore-presets, use the trackbars for this. The VCore is increased/decreased if a saved preset is
reached. Then use min./max. Load to determine when the FSB is decreased or increased and the two
delay options to set how long it should wait before increasing or decreasing. Now you can set a
max. CPU temp. If the CPU temp. is greater than this value, the FSB is not increased anymore. If
you have set the "FSB down on MT" (Max. Temp) checkbox, AutoFSB will decrease your FSB if the CPU
temp. is greater than max. Temp.

For example, max. Load is 80%, min. Load 20%, Delay (max) 30s, Delay (min) 2min and Max. Temp 45 with
"FSB down on MT" checked:
If the CPU load is greater than 80% for 30s it increases the FSB until CPU load is less than 80%
or to max. FSB. It stops increasing the FSB if the CPU temp is 45 degress. If the CPU load is less
than 20% for 2 minutes it decreases the FSB until CPU load is greater than 20% or until
min. FSB is reached. The FSB is also decreased if the CPU temp is greater than 45 degress (if
FSB down on MT is checked).

Help My system is frozen.

Asus a7v-133 w/ Athlon 1.4

The highest CPU speed I got from step 1 was 1466. That's with fsb 133 and multiplier at 11.0. The system wouldn't boot up at 11.5 and when I uped the voltage by .5 to 2.0 the monitor wouldn't turn on and the computer wouldn't shut off. I had to pull the plug which reset the bios to the minimum speed of 1024 I think? I am able to change voltage and multplier in increments of .5. I think the default vCore was 1.5.

So I took 1466 as my highest Mhz. On to step 2 I divided 1466 by 166 and got 8.8 which I rounded down to 8.5. When I restarted the system with 8.5 multiplier and 166 fsb the system froze. i.e. the monitor shut off and the computer wouldn't respond to the reset button or power switch. I unplugged it and plugged it back in but although the lights are on the computer, the monitor won't light up.

Help?!

Comment from Unregistered @ 2003/12/16
well I did a quick search and found out about resetting the bios by using the cmos pins to clear the memory or something like that. Anyway it booted right up and I have taken the "Wuss" route for the moment and am just running my 1.4 at 1.46666666. I might get back to the process of overclocking but for the moment I'll probably just fantasize about my dream system rather than about pushing a few more mhz of power out of this old donkey.

1.4G AMD's aren't quite the OC fellows. Last of the line, and producing up to date the most heat of any AMD CPU...
unless you got some exotic cooling, you'd better not piush it. (they also didn't have thermal control yet)

Comment from kristos @ 2004/01/25
I'm somewhat confused with all the voltage settings in the bios:

ok cpu voltage is pritty obvious but then;
Vmem = Vdimm = DDR SDRAM voltage ?
what's chipset voltage for?

Also, when upping the FSB, it says in the article that when my comp freezes or gets a bluescreen, I have to up the memory voltage but when I'm trying to get the tightest ram timings, I'm supposed to set te memory voltage to max? Why even bother? Why not set te memory voltage to max right away and see what fsb you can reach with it, then try tighten the ram timings...

And another question: Do I just mix my testing results in the order that was described in the article or is there no specific order and do I just bench to see what multiplier*FSB//timings gets me the best score?
(With "in order" I mean first multi*FSB then timings or first timings, then multi*FSB?)
Comment from kristos @ 2004/01/25
Oh crap, another thing I forgot to ask but I couldn't edit anymore (I'll register right after this )

Jmke: you said you set *Video Memory Cache Mode = disabled
that's the same as video ram cacheable = disabled ...right?

My guess is yes offcourse but I'm not 100% so I'd rather ask

PS: Anyone know a good site that explains bios settings really wel cuz' most manuals suck to say the very least and the manufacturers site's are usually no great help eather :/

It's to get a better understanding off the less obvious bios settings, what they do and what the best setting is performance wise.
Settings like in the background of this pic (under memory timings):

yep, that's the DDR voltage
the chipset voltage obviously controls ... the chipset voltage

(c) Howstuffworks.com
Chipsets
Chipsets provide the support for the processor chip on the motherboard. The chipset is the heart of the computer since it controls and determines how fast and which type of processor, memory, and slots are used


when you seem to hit a wall in raising the FSB, and nothing works to raise the FSB (the CPU can't cope with the speed, higher vmem, looser timings) it's your chipset that can't keep up with the high FSB

that's the wrong way, sorry. there's nothing really wrong with raising the voltage from start, but start with the tightest timings. when you're raising the FSB and you can't get higher, then you have to loosen the timings to get higher. if you set your timings and voltage to the maximum right away, you don't know if it's your memory who's actually stopping you from raising the FSB because the voltage and timings are already at the maximum

most people prefer tight timings, so they start with tight timings. when their FSB is about at the limit with the highest timings, they loosen the timings to see if the FSB gets higher and to see if the FSB gain with looser timings is faster

And what about when I can't get a higher multiplier, does upping the chipset voltage help to obtain higher mulitplier? Or does this ONLY work when you can't get FSB higher and upping your ram voltage doesn't help?

Well, it said in the article: to find your tightest timings; raise the memory voltage to max. So I figured: If you get stuck, it's either timings holding you back in reaching higher FSB or it's the proc (,mobo?) that just can't take higher FSB's, but it's not because of the voltage because it's already at max.

Other than that it's just like you said, testing to see what FSB//RAM timings works best

raising the chipset voltage only helps when the chipset can't go any higher, and you really can't know if it's your memory, CPU (!) or mainboard stopping you from raising the FSB

e.g. most nforce┬▓ boards need a higher chipset (vdd) voltage to work above 210~220mhz FSB

Comment from kristos @ 2004/01/28
When I try to reach my highest multiplier (166*XX; 177*XX;etc.), do I keep my memory on a 1:1 divider, do I keep it on it's standard Mhz (pc3200 @ 400Mhz), or does it make no difference at all in my quest for highest OC on multiplier?
Comment from TeuS @ 2004/01/28
1:1 is usually the best choice
Comment from jmke @ 2004/01/28
.. for performance is your memory is capable of the increased speeds
Comment from kristos @ 2004/01/29
if I set the ram on a 1:1 divider it'll be running at lower then specified Mhz
That shouldn't be a problem.

The guide is good but not specific enough can you clarify a couple of things for me?

1. You say about finding the max mhz which sounds easy enough however at which point should we stop raising the voltage? 1.9? i sure as heck aint raising the voltage on my 2600+ 333 t/bred to its maximum. So where should i stop ?

Also i noticed something really strange. I downloaded 3dmark 2001se and did the tests after each multiplier increase. Was doing great until i got to 13.5 and then it seemed as if the fps in the program wasnt picking up correctly and at the end the score was like only 6000 compared to teh 13385 when multiplier was at 13? what causes this

I have 1 gig dual ddr ram pc2700 cheapo stuff. and a radeon 9800 pro. My systsem is watercooled however the cpu temp reads 47 when multiplier is at 14 this good or bad?
