3.1GHz Opteron 165 -- The End :) - Page 3 - Overclock.net

I'm in at 3.1GHz

I can start to see the limits since the HT Link is now well over 1000MHz.

Prime is going!

Lyoko · 10-21-07

About 45mins in and everything is still looking good ^_^

Lyoko · 10-22-07

Ok. It's been 10 hours and it's stable

Time to go for 3.2GHz

Grats!!! such a fun chip (Opty 165)

enjoy it!

3.2GHz

Prime fails. Going to raise vcore a bit and if it fails, I'll back down.
Problem is, more voltage causes more heat which causes instability which leads to failed prime, but if I don't increase it I cant keep clocking. Last try.

Lyoko · 10-22-07

Ok. I just can't get 3.2 stable, so I'll try 3.15GHz

Nice man the best i can do on my opty 165

I was too lazy to get the new CPUZ :P

I guess the combination of less heat and raised PCI-E clock increased headroom to oc...! Thanks Duke!

For some the PCIe bump helps, but don't exceed 112! Considering the PCI @ 33 and the PCIe @ 100, every 3MHz increase on the PCe sould up the PCI 1MHz, so 112 would should result in a 37MHz PCI and be safe. Beyond 37 on the PCI could be problematic.

Less heat and what may be a balance in harmonics with the increased PCIe was a winner for you

I run 120 MHz on the PCIe bus

My efforts stop at 3.1GHz. I am more than satisfied with my performance, and I will be running 3DMark05 and 06 momentarily.
