Help me do my overclock (please bear with me)
 
I've read the info's & faqs on the board, but I couldn't get it completely linked to my mainboard - cpu - ram.

My System:
Athlon 2000+
256 MB Apacer PC-2700
MSI KT3 Ultra
GF4 Ti4200 64 MB

For the moment I didn't really dare push my GF4 Ti4200 to the limit, because I don't know how to find out where exactly is it's limit, so I bumped it up to 275/550 (stock 250/500).

Now the tricky part: BIOS settings

this is what MSI offers me (between brackets I'll put what it is now)

DRAM TIMING CONTROL
------------------------------

configure timing by: SPD/USER (SPD) (1)
SDRAM Frequency: SPD/FSB/FSB+33 MHz (FSB + 33)
SDRAM CAS#: 2,2.5,3 (auto because of (1) --> 2.5)
Row Precharge Time: 2T, 3T (auto because of (1))
RAS Pulse Width: 6T, 5T (auto because of (1))
RAS to CAS delay: 3T, 2T (auto because of (1))
Bank Interleave: Disabled, 2way, 4way (auto because of (1))
SDRAM Burst Length: 4QW, 8QW (8QW)
SDRAM 1T Command: Disabled, enabled (disabled)
Fast Command: normal, fast, ultra (ultra)

FREQUENCY/VOLTAGE CONTROL
----------------------------------------

Spread Spectrum: Disabled, ... (0.25%)
CPU FSB Clock: 100-220 MHz (135 MHz)
CPU Ratio: .... (Auto)
CPU Voltage: .... (Auto)
DDR Voltage: ... (Auto)
AGP Voltage: ... (Auto)

Some last notes:
a) my CPU is not unlocked
b) I have not much experience with this kinda thing, so please bear with me.
c) I have an Arctic Super Silent 2500 Cooler (yeah, lots of you think it sucks, but there's a big 80 MM blowhole right behind it) and 4 case fans (2 suckers in front, 1 blower in the back, 1 blower on top) and a 400 W PSU with one blower. Temps in windows range from 43C (absolute lowest) to about 49 - 50 C for CPU, case temps are at around 32-35 C.

Please help me make this a good overclock (first without unlocking). Thanks for you help!

You can find the optimal memory settings in the FAQ/INFO section. It's a very good guide written by Pilsy@icrontic, so read it. It will take only 5 minutes and solve your problem. :)

Resp. setting @ freq/volt ctrl:

- disabled
- 133FSB (standard), rise this untill you experience lockups
- auto (since you haven't unlocked your cpu)
- MAX 1.8vCore since you have sucky cooling. I suggest you keep it at 1.75vCore (auto)
- auto, try increasing it if you experience lockups at higher FSB
- auto

43 Idle, 50 Stressed, is it that bad? If I were to install a volcano 7+ would that be good? According to www.dansdata.com, this would be a very good solution, not to noisy on "medium" setting, however, I would like to know what 'not to noisy' means. (I don't like the fact of drilling holes in my mobo -PAL- and I don't want a tornado sound coming out of it - It's hard to sleep next to my pc allready)

EDIT:

also I can't find anything in the guide about:
- Row Precharge
- RAS Pulse Width
- RAS to CAS Delay
- SDRAM Burst Length

the other way I around, I don't know where to find "drive strength" in my bios.

What test do you like as CPU Burn in test?

UPDATE: I checked the CPU temp when doing a 10-loop Sisoft Sandra test (with MBM) it amounted to 51.

Does this have a grave impact on overclockability/temp? After all, it's merely some ram.

Also this is the 'not to noisy' Volcano 7+ (35dBa @ 4800 RPM)

Temps say absolutely nothing, stable overclocks do.

A v7+ cools well, but the fan is LOUD and you can't change it because of the unusual size (70mm).

Here's a guide helping you to decide which fan&HS to buy.

Most aggressive: 2T - 5T - 2T, 4Q

CpuBurn. :)
See the FAQ/INFO section for a donwloadlink.

Yes. Increasing FSB will not only increase the frequency at which your ram works, but also the PCI slots, AGP transfer speed, ...

I meant wether upping the DDR voltage will make a noticable difference in

a) temperature

b) FSB overclockability

I thought it wouldn't? ???

about the guide:

OC: Volcano 7(*) + papst NG (37dBa)

first, on the Papst.de site they say it's "only" 32 dBa
secondly: which is better a Volcano 7 with this fan, or a volcano 7+ with it's proprietary 70 mm fan? Does anybody have benches about this
thirdl & lastly: My current rig has 4x 29 dBa Casefans (AddA) and 1 Arctic Super silent 2500 (25 dBa) will it be much louder when changing this to Volcano 7(+)?

My MSI manual says that 8QW should be faster?

RichBa5tard 13th June 2002 09:12

Thanks for noticing the error, I meant the papst NH (37dB), not the NG.

You'll hear the difference between a ss2500 and a v7+ pretty well.


8Q is pr0lly faster. I didn't mention it cause I didn't knew your mb supports it.

Damn, I would like to test it before I buy it, because too noisy, is too noisy :(

RichBa5tard 13th June 2002 11:57

no such thing as a free lunch...

Quitest air heatsink&fan combo useful for OC: alpha 8045 + papst NH.

It will cost much though.

Could you give me a price guess, plus how it compares in raw power (so not in noise) to a Volcano 7 (+), Dan's Data says it still performs exceptionally well on medium speed and the noise is "only" 35 dBa then.

RichBa5tard 13th June 2002 16:10

Twice as expensive.

Thermaltake sound ratings are to be ignored, they sound A LOT louder than officially stated.

A papst NG 37dBa sounds much quieter than a Tt 31dBa fan... i know it sounds crazy but it is...
