IntelBurnTest question

WingZero30 · 22 Jun 2010 at 22:10

Hi guys I am trying to test my [email protected] for stability. The Vcore is currently 1.36875V. I first ran Intel burn 'standard' test with 5 iterations and it failed on 2nd iteration as Vcore was 1.36250V. So I upped it by one notch to the current value of 1.36875V.
I ran the same test again and after 5 iterations it passed the test. Not satisfied I just increased the iterations to 10 and ran the same test again. This time on the 4th iteration it failed :confused:

.
I then decided to test my cpu with 'maximum' test and lo it passed after 22s.Lol. I was like what the heck is happening. Also the temperature readings on CoreTemp were fluctuating sometimes from 65C to 52C and viceversa. So guys what could be the problem; is it could be some sort of bug?

not sure if heat is the issue or just lack of vCore?

up the vCore and run 20 loops!

[edit]

[email protected] . . . is that 8x400 or 9x356?

Its 356MHzX9!

What memory are you using and what speed is it running with the FSB @ 356MHz?

3GB (3X1GB)Corsair DDR2 800Mhz Gaming memory currently running at 427MHz(DDR2-854Mhz). FSB: DRAM is 5:6

Also I have 5850

Have you tested the memory separately and in advance for stable operation above 400MHz (DDR2-800)?

Memtest86+

Not yet. Is the Memtest similar to running prime or orthos. So I should decrease the ram speed back to default and run memtest.What should I be looking for in the memtest?

I can't figure out how to make the bootable cd with memtest. I followed all the instructions for making it in magic iso from tutorials i'd found but it won't boot. Might be my dvd rw drives which are the same model and 2 years old so i've just ordered 2 more as replacements and we shall see if that makes a difference.

If it's unstable then the fails will be randomly unstable when it constantly passes 20 or more runs I'd say it's safe to run prime.
