3DMark2001 screws up with 300+MHz FSB

[nCrusader]

Grrr :mad:

I find it strange, the processor can run SuperPi and Sandra benchies without any problems at 303MHz FSB. I can complete all the tests in 3DMark2001 @ 300MHz FSB but when the last test is finished and I get's back into windows, the programs screws up and forces me to close it. (I don't know how the message looks like in english).
Works perfect @ <299MHz FSB. (I use ic7-g)

A known issue? Anything I can do to prevent this?

Thanks for any input!

Hmm, back off memory speed with divider from 5:4 to 3:2 and see that helps.

Does it do it in the same place every time? can you run that test seperate and have it complete?

[nCrusader]

I'm already running with 3:2 ratio.

I've only tested running thru all the game tests in standard order and when nature is finished it happens. Will try to run each separate, didn't think about that.

[Ravilj]

what motherboard are you using?

nevermind the fsb issue, the 3:2 divider really kills ram bandwith. any chance of grabbing some pc4200 ram for 1:1 action?

You should look @ his sig, which says:
"2.4C @ 303FSB (3:2 ratio) SuperPi : 38s. Soon to be crushed by some Mushkin memory power..."

Well well, isn't 240 tight faster than 300 3-4-4-8?

[Jrocket]

Im not sure about that. Tight timings help alot, but a 60mhz difference might be enough to make up for that. Anyways, the pc3700eb is the best option right now! Fairly tight timings with pc4xxx type overclocked speeds!

[Ravilj]

At best, volt mod the board to get some more volts running through your mushkin and get it as high as you can running 5:4.

Bout the motherboard, if you have an Asus P4P800/P4C800 I'd suggest upping the AGP VDDQ voltage to 1.7v. That sorted all my stability issues out at +295FSB. now can run 3dmark at 308FSB (the slow down in windows is a problem but dont nothing to combat that yet).

Bah, can't belive nobody has said this yet, If you're going above 300mhz fsb, you need to up the agp mhz as well usually. If you're not doing that already you should try it. Agp voltage helps as well as Ravilj said.

yes but its VERY marginally faster, most people consider them equal. however pc4200 is cheaper and does not need a mod to do 300fsb either. I am going pc4200 when I get my a64, maybe there will be even better ram like pc4400 or pc4800(ddr600) thatll overclock to like 320-330fsb :slobber:

Since the RAM speed is not derived the same as the NF2 and P4 systems, that RAM is a very bad choice for A64 systems.

It doesn't matter if you can't get your RAM to do 300. Just use a ratio to let it run as fast as you can at the tightest timings. It will be faster than any 4000+ you put in there. And no PC4200 is not cheaper.

I use the Abit IC7-G

I have voltmoded the motherboard and when I get some time over I'll activate it and hope for 300FSB 5:4.

I've managed to run thru 3DMark @ 300FSB, as long as I don't runt all the test in the normal order, i works.

lalPOOO, Agp voltage is 1.65 if I recall right. How do you mean by increasing agp mhz? not run with fixed?

Thanks all.

[lalPOOO]

Well I doubt any of the dividers will allow you 'decent' agp/pci speeds at 300mhz FSB so try increasing it locked about 4 or so increments.

[macci]

Useing 1/8 AGP/PCI divider should work fine at 300FSB if your HDD can take 37.5MHz PCI clock.

I'm using a Western Digital 120GB SATA at the moment.. I have a seagte cuda4 somewhere.. hmm
