arghhhh, this 1t malarky makes my system unstable.

Whats your ram? and the timings and voltages its set at?

meaz · 3 Jul 2006 at 16:47

my ram is geil value pc3200 @ 2.5-3-3-5 timings - it was clocked @ 235MHz when I had the crash and that was only 2585mhz or something. I only run it 24/7 at 2617MHz as I change it with easytune for the last few FSB. Vdimm @ 2.8v highest the mobo will allow.

thanks

I`ve been running it at 2907MHz 24/7 since last night and it hasnt crashed, makes folding@home a bit faster than at 2617MHz. It is safe running 1.55v for a long time? or is it likely to make my chip subject to electromigration where it will deteriate in quality and need more vcore to do the same speed as before?

1.55v is nothing. Plenty of headroom.

Definatly. id run up to 1.65 24/7 if it was <55C load.

cool thanks for the help. Its still not crashed at 2900 and its at 44c full folding load according so speedfan with a 33c case temp.

thats a damn fine chip you have mate, when you sell it eventually make sure its to someone with phase change, would love to see what that chip would do with sub zero temps!

I honestly wouldnt trust CPU-Z voltage readings. It actually more likely to be closer to what its actually set to in the bios. 45c load on 1.6v @ 3.1ghz is just wrong also, unless you're on water.

Weird this - seen a lot of people complain that CPU-Z isn't accurate with the voltage readout.

Yet since I upgraded mine to v1.35, it reports very accurately. hmm.

it crashed at 2.9ghz 1.55v so have upped it to 1.6 this is undervolted to 1.56v - 1.584v according to cpu-z latest build. I am thinking its the Geil Value PC3200 that doesn't like running at 240MHz 24/7 folding, folding needs total stability to run even more than seti@Home so the system would probably be prime stable at 1.55v just not folding stable. If it crashes again I will lower the voltage back to 1.55v and set the divider from 183 to 166 and hopefully that'll sort it out.

Yeah, youre on the right track methinks ... lower that mem divider all the way down and eliminate it as a source of problems.

Also, consider your power regulator could be overheating... have you had any cutouts or just 'general' instability while running F@H ?

just last night after a day of running folding it crashed, the screen just went blue no blue screen just the screen was blue. IVe never seen that happen before. Was a strange one, it could be the power regulaltors overheating as its only an nForce3 250gb cheap mobo.
