Hardware instability

john6205 · 2006-11-21, 00:17

I had 2 problems, one with software and one with hardware...

Software problem solved. I needed a clean reinstall of windows to get Prime Torture Test Blend to run. Now that it is running, I am just barely unstable.

Rig: 3.4EE - 478, ASUS p4p800 deluxe, 6 HD, Nvidia 6800GT AGP videocard, Thermaltake 480W ps, 1G OCZ PC3200 ram (2X512). All other PCI cards are pulled.

I have run prime torture test blend numerous times from XP and from the LINUX A: drive boot disk suggested on another thread, and they both detect hardware errors anywhere from 1 hr to 8 hrs into the test under all of the scenarios I have tried.

My vcore is bumped to 1.6v
My memory is at 2.85v (MFG says 2.8 is correct)
My AGP is bumped to 1.6v (not sure why, suggested by a pal)

Heat on the Proc never gets above 47C, MB never above 41C.

I am still slightly unstable, with EVERY test returning the following message "rounding 0.5, expected 0.4".

I can restart the test immediately with no ill effects, but never stable...

HELP?

Still sounds like a bad power supply...

Do this at you own peril: In your BIOS-->exit-->Load setup defaults

Before you do, take notes on every setting in your BIOS

What a pain. Anyways...

Using Linux A: drive boot disk to test stability w/ mprime. All drives and PCI cards pulled. Only thing connected is mouse, keyboard, monitor, memory, 6800GT video card, CPU, PSU.

Reset BIOS to defaults. Fail test within 1 hr with "rounding error 0.5, expected less than 0.4"

Swapped Processors back AGAIN to 2.8C, failed with same results within 1 hr.

Pull 1 stick of memory, same results within 2 hrs.

Pull other stick of memory, same results within 5 hrs.

AGAIN STOCK SETTINGS FOR ALL THIS TESTING. To me, it's not the memory or the proc.

What's left? PSU or the motherboard I guess. The mouse, videocard, or the keyboard wouldn't do this??

SO, long story short, I ordered this PSU from newegg today:

Hopefully it will be OK for my machine to replace my Thermaltake 480W psu with that ANTEC 650W psu. An online watt calc. out there in the world said I need at least 550W to be safe. I hope I bought a good one.

New PS, same failure

Must be the MOBO or the memory, but I think I have eliminated the memory from the equation.

Time for a new MOBO??

HELP.

What are the identification codes on your memory chips?

Also, what are all of the BIOS settings for the memory?
