IntelBurnTest - The new stress-testing program

[Amurtigress]

Very interesting. Thanks for sharing this. So...changing the PCI-E frequency will change a strap? I'm not very knowlegable about this frequency. I will definataly give this a try though. I am still searching for the answer as to why I am BurnTest and Prime stable at 400 MHz but become Prime unstable with only a small increase in FSB to 425 MHz. (This is only 25 MHz above default on the FSB). No one else seems to have had any solid advice regarding the IBT/Prime discrepancy that several others have been experiencing as well.

It is just a guess that it could be an internal clock divider or something else the BIOS does when going away from the default clock. I wish I knew more about the internals, myself.

<edit> Erm, I just saw mikeyakame's post on this... </edit>

My first 7:20h run was done at FSB 433, last night I cranked my Q9300 up to FSB 460 with no voltage changes, and it ran stable for 7:30h again. At around 470 my board bails out with a FSB wall, but I knew about it before I bought it.

Currently running my Q9300 at 3455 MHz, and happily stable!

I'm looking forward to your results. Frankly, having such a CPU and hitting a wall at 425 is nasty. But the X38 chipset is known to not overclock well on 45 nm Quads. Hence my change to the P5Q3 board....I had the Maximus Formula myself. It crapped out at 436.
