System freezing under load, CPU isn't overheating

I just assembled my new computer with the listed specs.Currently it is stable while idle, however if I run an 8+MB test on superpi, the computer locks up; the screen freezes and all my usb items lose power - with no BSOD.When I first had the rig put together, I was trying to install WinXP 64-bit, and I experienced......

if it says 2.1v it needs 2.1v no more and no less.

the timings were all factory, and the voltage setting said 1.90xxx volts, and the realtime readout said 1.88xx something. I increased it a step to 1.95xx, and tried again, had a little success, but don't want to overdo the voltage. I ended up going to Fry's and buying myself some other ram, it's rated at 2volts and the setting was at 1.9 when i first put it it. It worked flawlessly. I'll be returning the ram I have to newegg :(

Go in your BIOS and set the RAM voltage and timings to specification. I bet its not gettin enough volts or the latencies are set wrong.

Methodically went through all 4 sticks of ram I had. One stick fails to let the computer boot. Two sticks will let it boot, but then cause the computer to freeze during memory tests in prime95. The last stick will boot, run the test, but gives FATAL ERRORS in rounding. what the hell is up with that?

I ran prime95 twice.  

The first time went 4 minutes without any problems, then I stopped it.

The second time, I got to 5 minutes and two of the worker threads had errors.

"FATAL ERROR: Rounding was .4936523438, expected less than 0.4"

It refers me to Stress.txt, which does not seem to exist. The output text files in the same directory as prime95 also refer me to Stress.txt. Searched my hard drive for it, nothing.

Also having trouble with my 10 year old floppy drive, it doesn't want to work. I've been running memory tests in XP.

 

I was just able to successfully complete an 8MB superpi test with the second stick of ram, but I'm still worried about the errors that showed up in the memory test.

I'm not using 64-bit. I'm using 32-bit.

Since you are using 64bit XP, my first concern would be if superpi is fully compatible.  It is 4 years old.  And 64XP is not exactly unsensitive to many 32 bit programs.  I assume you have not started overclocking yet.    If there is a problem, I would guess it is with software incompatibility, followed by the CPU itself, and perhaps the interaction at the FSB (if an Intel?) if your CPU is running at the motherboard's max FSB speed.

I trust you tested memory first with memtest, and the CPU with Prime95 or Sandra using bootable disks so you are not dependent upon XP's behavior?

24 errors so far in the second stick of ram, but the systemhas not frozen.

Could it be the motherboard? what's more likely? all my sticks of ram are messed up or my motherboard is malfunctioning?

I tried running a windows based memory test and the computer froze in a matter of seconds.

I replaced the stick and am re-running the test. Hopefully this will definitively show that the problem is the ram.
