Opteron 144 Overclocking

Hey Guys,

I've been playing around with the Opteron 144 that Zebo sent me. So far, the best I've been able to do is 2.8ghz (311HTT, 9x multiplier, 3x HT multiplier, DDR266 (DDR400 effectively)).

It seems as though my motherboard is holding me back from going higher. The chip is at a modest 1.475v right now and stable at 2.8ghz. I tried booting at 2.88ghz (320HTT) and it would not run Prime for more than 5 minutes (but it booted into Windows just fine).

So...I'm wondering if my motherboard is holding me back, and if there's anything I can do to work around the ~311HTT limitation.

I'm curious as to why I've been forced to use a 9x multiplier when the chip runs on an 11x multiplier by default...

thats what i use on my 148 @2899
The BIOS won't let me select an 11 multiplier...it only has "auto", then 9 and lower. :(

i have a DFI LPnf4
Perhaps.

It could have been the chip crapping out at that speed, but I doubt it.

Try a lower multiplier, 8, and increase the HTT to 320. If it still isn't stable, then you know it is the motherboard. If it is stable, then the bottleneck is your CPU.

I don't know what you're talking about with the multipliers; the 144 is a 1.8GHz default chip and has a 9x multiplier (200x9=1800)

it's a 9x chip... the 146 is the 10x chip, 148 11x... 2.8 on air on a 144 is a good oc... i only can get 2.8 out of my 146...

You cant get an 11x multi with the 144. That's the multi for the 148, and they're locked out above what your chip is stock. 2.8 is a good OC with that chip unless you're doing some exotic cooling. For reference, my 148 is at 2.86 at stock volts.

Ya it's a 9x multiplier; my bad. I think I'll just leave it at 2.8ghz. Zebo even said that he ran it at 2.8.
