Opteron overclocking help

post #1 of 10
Thread Starter 
I'm pretty new to overclocking and building computers in general. I need some help figuring out what setting I should run my processor at. Right now it's at 2.02GHZ with 225mhz x 9. My question is how low should i drop the multiplier and raise the fsb speed for best setting and when will I know to stop pushing? Thanx in advance for your help and patience.

Depending on the stepping (cpu code on top of the cpu itself) you can push that 165 very far indeed, a lot of people love that cpu.

How far do you wish to go is the question? I think it could easily reach 2.8Ghz with a good cooling

I would love to get that high. As of right now I can't seem to figure out how run it any higher since when I try to raise the speed even up to 235 I can't even start up. Do I need to change anything else besides cpu speed and multiplier? What exactly does the PCIE speed have to do with it all? Thanx again.

I don't know anything about evga s939 mobos but I think that's your problem...

There is nothing to do with PCI-E speed, leave it as is...

there should be an option to lock the pci frequency, if there is lock it to 100mhz.

Here is a link to a useful guide.....

I used to own that board, so I can help you out. First of, at 235*9 your most likely being limited by your ram, go ahead and drop your ram down to a 166 divider. Then try booting. You should boot fine.

LOL, I just did that then logged back here to find you guys telling me to do that. I was just trying things so I thought I'd pull out that extra memory i put in last week. I'm up to 2.26ghz now and so far no problems. Why did taking that memory out work? Also thanx for the PCIE advice, cuz i was running it at 105mhz and 110 which might have been screwing things up too.

The on die memory controllers on the amd64 chips dont like addressing 4 sticks of ram at once. Thats why taking out the ram (combined with lowering the ram divider) helped out. You will be hitting the big 3.0 in no time!
