i had my ram in slots 1-2 - errors on test 6 of memtest and in prime95
i tested the sticks individualy - no errors
i tested the sticks in slots 3-4 in dual channel - errors on test 6 of memtest

this is what i got on memtest (OCZ version and reg version)

failing address
0003c7a5af8
0003c8a5af8

good - ffffffff
bad - fff7ffff
err-bits 000080000

basically it only seems to happen when i have the ram in dual channel. i have used 2.5-3-3-7 at 2t and 2.5-3-3-8 2t and got the same errors...

Round off errors are usually from overclocking, and or heat (I run prime 24/7 on a ~dozen machines). Your CPU load temps seem a bit warm for a stock 3000+ I get ~48c on a Winchester at 2.6, full load Prime95.


Check and see what the rated RAM voltage is too, the BIOS defaults to 2.6. Most performance RAM is rated for 2.8

You can also try turning off the "aggressive timing" in the BIOS.

The first thing many will say is to upgrade your MB to the latest bios, then try relaxed timings.

A64 chips don't run very well at those fancy 2225 timings. I have to run at 2336. People who OC to the extreme run at 2.5, 3, 3, 7 or even 2.5, 3, 3, 10.

what slots are your ram in on the motherboard, I know with that board if you do not have it in the right dimms then you will get errors and crashs in dual DDR mode.

My Athlon runs perfectly fine at 2.5-2-2-10 1T

I think what you meant is that timings aren't too important to the A64, not that they don't run well with those timings.

Edit: It's also 100% stable at 2-2-2-5 1T "Aggressive timings" when I run at stock speeds.

Is your CPU a 90nm? I know a lot of peeps had to update the BIOS to a 1.4 or something in order for the CPU to work properly...

Try dopiing the HT down to 4 or 3. I'll bet that will solve the problem.
