CPU Failing Super Pi

[Stan_Lite]

Can you borrow CPU and memory from anyone to test - see whether it's the components or the board?

You say there are no options for changing memory and chipset voltages in your bios. Have you tried ctr+F1 whilst in the bios to see if there is an advanced bios - one of my cheapo boards requires this in order to change the memory settings (can't remember which board ).

Does it pass with your usual overclock?

OH YEH, and also..

If running dual superpi, you MUST run each from a seperate folder. If you run 2 from the same folder, one instantly errors out..

Lawrywild - Thanks, found the memory voltage option. I set the voltage to high and tried from two separate folders but it still gets errors.

BigStan - I don't know anyone with other components I could try. I do have some ram in a old pc. I will try that tomorrow. Pressing Ctrl+F1 doesn't bring up any new options.

Trojan698 - It sometimes fails when the cpu is at stock speeds, it used to be stable at 2.7ghz but it has been kept at stock for the last month.

How long was it overclocked for and what voltage were you using?

For 24/7 use I had it at stock voltage at 2.55ghz. This was only for about 2 months.
I did put it up to 2.7ghz with 1.55V but this was only for a few days and about 1 and a half months ago.
I bought the cpu in April, I doubt I had it long enough for the effects of overclocking to damage the cpu.

Just fixed it.

Went into the bios and enabled the flexibility option, this is meant to improve the compatibility with the ram. Now it's enabled it has passed super pi when at 2.4ghz.
Not sure why this fixed it as memtest showed no errors and i've been using the ram with the option disabled since I got the pc.

I'll try getting it back up to my normal overclock and see if it's stable, then run prime for a few hours.

Thanks for all the help

Knew i'td be your RAM.
