Are you still running at 12 x 254?

Yep. I figure it's safe-ish to bump up the multi?

Bump multi x.5,if that fails lower ref clock to 250 and try again.
How low did you get the cpu volts and still be stable?

Its completely safe to bump the Multiplier. Its not safe to run the FSB so stinking high The higher the FSB the hotter that chip is going to run because the more voltage it will need to be stable. Bring your FSB down to 222 and your multiplier to 15 if you want to run 3.33Ghz. You will have a 200% better chance of being stable. The lower your FSB the better the stability, hence why the higher multiplier Processors cost more.

Athalon II X4 620 89.99 Base Clock 200Mhz Multiplier 13 -2600Mhz
Athalon II X4 630 94.99 Base Clock 200Mhz Multiplier 14 -2800Mhz
Athalon II X4 635 97.99 Base Clock 200Mhz Multiplier 14.5 -2900Mhz
Athalon II X4 640 99.99 Base Clock 200Mhz Multiplier 15 -3000Mhz
Athalon II X4 645 104.99 Base Clock 200Mhz Multiplier 15.5 -3100Mhz

Its all the exact same chip, with the 635 and up being the C3 stepping revision, which is supposed to mean they will clock better, but it I have not see the real impact of such.

He's shooting for 3.8.
He's going to need all of that 250+ ref clock to get there:p

I see. In that case I have subbed this thread as we will need some major proof proof.gif. There are a bunch of 640 owners that cannot get stable past 3.6 without a terrible amount of voltage including myself and several others using the same board. I can boot into 3.8 but not long enough to shoot a CPU-z validation. I have shot and ran a few minets of prime on 3.75 but the Vcore was 1.57. Seems way to high for logic. But i will note that I only hit 52c during that attempt.


My best 8hour Stable Settings:
CPU FSB 240
CPU Mult: 15x
CPU Freq: 3600
CPU_NB Mult:8x
CPU_NB Freq: 1920
FSB:RAM Ratio: 1:3.33
RAM Freq: 1600
HT Mult: 8x
HT Freq: 1920
Voltages
CPU VDD: Auto (1.25)
CPU_NB VDD: Auto(1.25)
CPU Voltage: 1.53
CPU NB Voltage: Auto(1.2)
Dram Voltage: 1.65
NB Voltage: 1.31
HT Link: Auto (1.20)
