Hey all,
I've been working today on increasing my overclock on my rig, and I ran Prime95 Torture Test, planning on doing a 24 hour stability test. However, it seems to have crashed after 1 hour, 20 minutes with a hardware error. Since it was able to run for that period of time, it seems that I have not hit the limit of my chip(Athlon 64 2800+, Newcastle, CG revision). When I appear to hit a limit, it seems to crash Prime95 immediately (When I rise over 2.5Ghz), indeed, it was still running under 50 C. However, my overclock is rather high, at 9x275 (I'm running 5:4 mem divider, and 1.525 VCore in bios, reads 1.600V in CPU-Z). I would really like to be able to maintain this overclock. I have a few ideas as what may be wrong, but would appreciate guidance.
I am positive the problem is not my memory (Corsair XMS-PC3200 OC@ DDR 450 2.5-3-3-7), as it has run at DDR470 stable, and I was running the CPU intensive test. I suspect that my power supply may be the problem (420W, came with Raidmax case) the rails have good voltages according to monitoring software, but I think the -12V rail may be overvolting (-13.02V). This rail has been this high since I got the case.
If it is in fact the PSU that is causing me issues, what would be a good powersupply to purchase? If I can sell my current graphics card (9800 Pro EZ), I will upgrade to a BFG 6800 Ultra OC or 6800 GT OC, so I may need the PSU upgrade regardless in a few months.
Thanks for any help,
Jaimie
