Yeah yeah, take the ****, I'm a mod and I can ban you :p

Going to see just how far I can push it.

Anyone else willing post some overclocking results for Socket F systems? Would be interesting to see how some of the cheaper Opterons do as well.

Don't think NUMA works in XP but Vista, not only the normal driver issues with Vista but I struggled to get all 4 cores working as well.

Got 4 1GB sticks, so I think it assigns 2GB to each socket, if it had NUMA each socket could access the RAM on the other, but as far as I'm aware XP doesn't support NUMA.

I'll post some pics in a bit.

Meh, off to a great start, stressing at 2.7GHz and it rebooted and killed my Windows install in the process :( .

Jokester
 
Nah, got it working fine at 2.8GHz at stock volts, don't know what happened when it took out my installation.

Jokester
 
Nah, checking it in CPU-Z and the 2 cores on the 2nd chip are definitely lagging behind the first two in terms tests done in prime.

I'll run some Super-Pi's that might highlight it better.

Checked the BIOS and everything is set to 1000MHz, ran Superpi on each processor and for the first one I get about 32s, on the second 42s :eek:

:o

Memory for some reason is running at 200MHz instead of 400MHz. Going to update it to the latest BIOS while I'm at it.

Edit: 3GHz :)
 
Sorted my RAM out, dropped the times to 28s and 36s so there's a definite speed difference between the chips so it does seem that the other chips HT is only running at 200MHz instead of 1000MHz.

You can run a quad + SLI on a lot less but if you're looking to get the best stable overclock you can get you can't skimp on the PSU.

This is the best PSU I've ever had for stability, the only downside to it is the noise it makes on load.

I've identified what it was that killed my Windows, was running the RAM at 200MHz instead of 400MHz.

Looks like prime stable at 3GHz on stock volts, but testing I did earlier this morning points to it only going to 3.1GHz on the board max volts (1.55V). Now doing extended testing.

At 3.05GHz, Kentsfield at 3.6GHz gets about 20-25% more in the CPU benchmark. Can get more out of it but not much.
