hwbot: amd competition
 

i guess all of you know of the AMD-competition.

i think it's a good opportunity to remove those old PC's down from the attic :).

I started OC'ing a Sempron +2400 without much succes. I use a Asus A7N8X-E Deluxe (without wifi-add-on). The sempron quits posting at 220 Mhz FSB and 1.750 Vcore.

(source: xbitlabs.com)

So if any of you guys know a hack how to overcome this problem, i guess i'm stuck with an OC of 210-220 Mhz FSB and memory (PC3200 - brand: Aqpi or the sort) running at 100% CL 6-3-3-2.5.

I can try switching CPU's (Athlon +1800 and +2000), but i guess i'll be hitting the FSB-wall rather quickly. (Or i can try using another MSI motherboard).

I had better hopes OC'ing my old K6-2 400. After some attempts fidling with the dip-switches (yeah, switches on the motherboard ;-)), i ended up with a multi 4.5 and FSB 112 Mhz. I use 133 Mhz ram, so no problem there. The problem upping the FSB is that i cannot lock the AGP-bus @66 Mhz. (Soyo SY-5EHM motherboard).

I lapped the CPU and cooler and applied Arctic Silver (best imo). The PC comes through post, but i didn't find a compatible keyboard and mouse :mad:

For the A7N8X, don't know if it uses same chips as: http://www.xtremesystems.org/forums/...ead.php?t=5167 ; vcore & vmem mod inside

anything I can help you with, I have collected lots of antique stuff...

i think it's the same board, but at the moment i don't have droop or the sort, it just won't go over 220 Mhz FSB. I don't have the required hardware to make Vmod's.

When i have some spare time i'll install other Athlon XP's instead of the sempron and the other S462 mobo.

I'll see if i can unlock the sempron's multiplier.

edit: since my mb has a nforce2 chipset, it is hardly possible to unlock the sempron. I'll have to search for my other s462 mb.

something to get you started, 3941pts, xp-m@2300MHz / 9800PRO

still struggling to boot the Sempron 2400... crappy cpu/memory combo. It fails at 220 FSB and memory at 100% speed.

i'm going to install my GeiL DDR's which are fairly good oc'ers (450-460 Mhz at 6-3-3-2.5) and take another run at it.

well my setup isn't completely hassle free either, I can run benchmarks fine the one moment while the day after the machine just refuses to get through POST.
generally speaking 220MHz fsb is the wall for many NF2 boards without mods, I use 8rdaVcore software to software tweak the FSB up to the desired speeds.

frack, my K6-2 fails @ installing winXP :(

luck is not on my side...

hehe, made my submission. Do any of you guys have a K6-III or K6II+ >500 Mhz?

I didn't get mine over 500 Mhz, i got thru post, but xp didn't run at these settings...

http://hwbot.org/submission/2178629_...0mhz_527_marks

nope, none of them are booting, the Pentiums are no problem however. The nf7 board is being a pain in the ***... or maybe broken too I dunno, memory errors all over the place even at 133MHz. All was going good, from one boot to another, just hopeless. Going to t(/f)ry one of stock bios, lucky me I keep most of my files stored somewhere local, they're pretty hard to find these days :)

edit: if you want you may always pick up the K6 cpu and try it yourself. It's stock 500MHz, does(/did) 600MHz no problem.

I think I have a K6/2 that did 600+, but need to check if it's still alive

http://hwbot.org/submission/622500_m..._45sec_990m s

could it be that it the K6-II/500 I have, is in fact yours? Sorry MIA :(

Ehr, possible I guess. I'll check the attic :p

submitted 3700 score for K7, 6th spot, overall we're 3rd now :|

Non working motherboard with 30+ Durons = fail.
Who is willing to test these ?

AMD K6-2 somewhere, but can't seem to find it :(

what do you mean with test? see if the cpu still works? you can try the current K7 board I have here but be quick I'll be building it inside a case somewhere next week.

@jerre
some tips: don't spend time overclocking the gpu, it won't do much certainly when using the K6 setup. No way to select a higher multiplier on that board? Can you get x5? I guess the best thing to do is focus on highest cpu clock, 2nd best thing is get a decent FSB frequency. If your bios doesn't allow for altering much memory settings maybe you can try wcpredit or something

regarding your K7 setup, I have the A7V8X-X which should be practically the some board as yours, but slower (Via chipset), does it also come with a 'extra volts' jumper near the cpu socket, at the top of the board? Maybe it is? I also have few unlocked cpu's, should work out quite well with your nf board, you won't reach first place but, who knows maybe close :)

i tweaked memory and cache settings: 8 marks more. @2.7Vcore i can post @504 mhz - 4.5x 112fsb - but winxp fails. I can also post 5x 100 fsb.No go fsb 124.

i can increase vcore, cpu remains cool with 2 fans.

I've read that the NF2 Chipset doesn't like unlocked CPU's. I have unlocked a Athlon +1800 but haven't tested it. It doesn't work: made all the bridges, only that works is the vcore-bridge. Multiplier crashes after only the slightest change (11.5x => 12x = no post.). FSB: from 133 to 141: unstable.

You can try some higher Vcore setting but I don't think it will change much. On K6 the chipset of the board can also have a measurable impact on system performance, Ali chipset is one of the most performant even without tweaking. Cache, you'r good with 1mb, many board only have 512mb. You're correct with the PCI/AGP lock, that's why most boards/setups have a problem running at over 112MHz, at 124MHz you'd probable risk data corruption but hey no problem if that is a benchmarking operating system. Only few boards have the 133/33 lock, not more than 5 boards, and from those who have such board the 133MHz option is non-bootable (as it is with me :p)

I don't know if they really dislike unlocked cpu's, haven't really heard of that, but what I do know is that most WR's are made with unlocked cpu's so I don't think they're really a pain in the *** for your mobo :) 10x220 gives you 2200MHz, yes try the unlocked maybe you'll get 2300~2500MHz out of it. If your board stops at 220MHz you don't really have other options unless you voltmod it :)

Scored about 5200pts with 148 opteron. For K8, we definitely need a dual core :-/

3800x2 here, only coldbug at 5°.

i got the info concerning the NF2 chipset and unlocked Sempron/XP from: http://www.ocinside.de/go_e.html?/ht...overclock.html
My sempron is year 04, week 49, so it is probably not unlockable on the Asus mb. I have an old MSI KT3 ultra, it is possible that it'll work on that mobo.

the KT3 is dead: it boots, but after 1 minute it reboots, i'm out of options in the K7 range...

I can lend my K7-cpu's: +1800, +2200 (both athlon), one +2400 Sempron

scored 3979 marks with the sempron.

goeie pie, ik ga proberen met de thuban onder LN2 om te zien hoever dat we geraken...

I was just thinking about settings up my 2500+, but I doubt I'll get over that 3900 score (it maxes out at about 2,3Ghz), altough my mem goes to 210Mhz@2-2-3-11

my sempron is clocked at 2220 Mhz (220 à 222 Fsb) instead of 1660 Mhz (166 FSB x 10 multi), so 2.3 Ghz is higher then my OC ;), my mem isx timed at 2.5-2-3-5. It fails at tighter settings.

Finally back internet (from work ;-) ).
If you want Albrecht, you can borrow my 1090T.

in that case you might even beat my 3990 score, 2400MHz but VIA chipset is a lot slower than NF2

scored 3996 :) but too low: place 5 is 4200'ish

Luc, heb jij die X2 nog?

Voor K8 kan ik met m'n 148 niet echt veel aanvangen ... need dual core :)

Ja, die heb ik nog.
is wel maar een 3800x2 maar doet toch 2700 mhz on air.

Ook nog bord ervoor?

Asus A8N SLI en A8N-32 SLI deluxe, hopelijk werkt één van de twee nog.
Wat moet er juist gebeuren, PCmark 04 ?

jup

Ok, zal zien wat ik kan doen.
Idem als PCmark05 ATi 5870 als GC ?

ja ik hoop voor jou dat de grammar test goe doorloopt, indien niet de affinity op 1 core zetten net eer ie begint

SSD en ram speed maken gene zak uit precies, tis puur CPU

Scored 4227, I'm roughly 40 points short but can't clock any higher, system is at edge of stability, cpu fails at anything higher than 2.4GHz due to the lack of vcore on this board compared to the A7V8X-X I own.

On a sidenote, did you know about bios mod for your bord?

Gave it a try, don't panic I used one of my own BIOS chips so there is always a way of going back in case the Flash goes wrong :p The new BIOS is nothing too special though, not the extra cpu volts I was looking for... You can now set chipset voltage up to 1.9V but some people report it doesn't really do anything. I can confirm that, the chipset not clocking higher than ~225MHz has not much to do with chipset voltage. Furthermore you can now also set VDIMM up to 2.9V instead of 2.8V. O well, better than nothing right :) When I return your board I'll swap in the original bios chip again ;)

Me and uberlord Massman scored a nice 18.7K yesterday with the 965BE at 6.1Ghz... but we still have issues to get test 3 optimised... no idea how the top 2 got them scores

Increased NB speeds : no gain
High ram clocks and tight timings : very little gain
GPU overclock : small gain
SSD vs HD : no gain

seems pure CPU power and correct 1 core affinity with test 3... we tested XP vs Win7 32bit/64bit... we favoured the 32Bit Win7 install...

lets hope Luc can do a nice score with the 3800X2 CPU...
