HELP my A64 system is unstable.

[anthrax]

I have recently setup my Athlon 64 System but it crashes in 3D Mark 2001 and Call of Duty.

Athlon 64 3500+ (2530 MHz (230 x 11) (1.6 V)
Cooler Master Hyper 6 Heat Sink
Gigabyte K8NSNXP-939 (232 HTT x 11)
2 X DDR 2700 (Running at only 150MHz) in dual channel.
Winfast A400GT (390/1050)
SPI-350W PSU

Super PI 8M runs fine.
3D Mark 2001 Crashes to desktop or reboots.

Any suggestion of possible causes?

possibly your 3dMark needs a patch if its an older build..

Hmm, My 3Dmark2001 is build 340. Thats the final version of it. ALso, I doubt a faulty 3d mark program will cause the system the reboot.

I know you said Super Pi 8M ran fine, but try running Memtest 86 just in case. Similar thing happened to me with one of my older computers.

Kind Regards,

Hmm, Thanks, the memory could be the issue. .I am using a 1 generic DDR 2700 as well a 1 Kingston DDR2700 module there..


Could it by any chance be a Power issue?

 

[Randawl]

Always a chance of it being a power issue, but it's typically more difficult to troubleshoot unless you have a spare lying around. If no errors are found with your memory, then maybe you should give it a shot.

350W might be cutting it a little close for your rig. If you wanted an excuse to get a beefier PSU, here's your chance Looks like you already know to buy name-brand, so I won't chant my PSU mantras at you. You might want to try bumping your memory voltages too. For PC2700, 2.7 volts sounds like enough to rule out simple voltage starvation on the RAM as the problem.

check your ram timings, make sure they aren't very aggressive. This could also be a vcore setting issue, as you are overclocking your 3500. See if cranking it up .5 helps. Also, get to ddr 400 ASAP. You have a dual channel mobo - the finishing touches on athlon 64 but you are bottlenecking yourself with slow ram. I'm not 100 percent sure about this, but if your FSB is only 150, then multiplied by the default 4x HT multiplier you're only at 600 mhz HT.

Also, how are you getting a cpu clock of 230 and a multiplier of 11 with an fsb of only 150? Perhaps I don't know about athlon64 overclocking at all.
