Suggestions for overclocking

[Creideike]

I just installed an Opteron 165 and I can not get a clean POST with the two FSB settings that I have tried. I tried to first set my FSB to 266 with a 9X multiplier = 2394Mhz and I also tried 245 FSB.

On both of these setting I had HTT set to 3x, I had my RAM set to 333Mhz (should be the 5/6 divider), I disabled PEG-Link, had DDR voltage 1.75, and played with CPU voltage from 1.35-1.50 V (1.5 being highest MB will allow). With the FSB at 245 I was able to start booting Windows till it froze, and then when I restarted it told me I had a POST problem and needed to change BIOS settings (same thing I was getting with the FSB at 266). The current BIOS version I am running is 1016.

Does anyone have any suggestions? Is this a bad BIOS version? Has anyone had a similar experience with the Opteron 165 on an A8N-SLI Deluxe MB?

Thank you for any assistance or suggestion you may have.

Well I have some updated info if it helps anyone. I tried to OCing my system a few more time last nigh. This time I dropped my memory to 266 MHz, and I did not get a problem till Windows was loading, then right as my speakers gave a little thud noise to indicate windows had activate my sound card, widows froze. I then had to restart, but this time I was not getting any POST issues just the Windows lock up during start-up.

Could this be my sound card not being able to handle the increased BUS speed, and if so is there a way I can limit this speed? Also does increasing the CPU Frequency (aka FSB) raise the BUS speeds form my SATA drives and PCI-E graphics card?

Again any help is appreciated.

You are not going to get 266 on 2-2-2-5 settings. Loosing up the timings first and work your way back down.

Asus has bios version 1017 out right now, its in beta but it might help.

Thank you all for your help.

have you made sure the pci speed is locked at 33.33, that may be causing the sound card problems.

I did, I think it may be a memory issue since I am useing 4 512 sticks of RAM. At least pulling two sticks out will be the next thing I will try to get my overclocks higher.

Anyone know How do I find out the stepping of my Opteron 165 and how that relates to its OC potential? I never though that some retail CPUs of the same make, model and core could be better than others.
