overclocking athlon ii x4 620?

[dpk33]

so what do i leave the cpu/nb voltage at? and the dram voltage? and the northbridge voltage is at 1.2. is that alright?

 

[Vesku]

CPU-NB VDD VOltage @1.275, CPU-NB Voltage @1.329, and NB Voltage @1.221

That's the settings from the link to someone elses OC with the same motherboard, they considered those safe for 24/7.

ok at these settings, and 1.45 cpu volts, i can't get past 248 fsb without stability issues. does that mean that is the furthest this chip will go?

I'm sorry if this was menitoned before, but what are these exact values supposed to be:
CPU/NB Voltage
CPU VDDA Voltage
DRAM Voltage
HT Voltage
NB Voltage

 

[Vesku]

1.329 CPU/NB Voltage
1.4625 CPU VDD Voltage (can try up to 1.475ish)
1.5 (or whatever your RAM states) DRAM Voltage
Auto HT Voltage
1.21 NB Voltage
1.275 CPU-NB VDD

These are the settings reported stable with the same motherboard from: http://forums.overclockersclub.com/index.php?showtopic=173971

YMMV, OCing involves some unavoidable risk, don't touch electronic bits while the computer is plugged in, etc.

thx gg

lol

 

[dpk33]

there's no option for CPU-NB VDD. should i be worried?

 

[Vesku]

I'd double check for it in the bios listing of your motherboard manual, but if you can't find it oh well. Just take the highest stable FSB you can find within those voltages.

 

[dpk33]

the cpu vdda voltages only range from 2.50 to 2.80 in intervals of 0.1.

 

[Vesku]

Seems the MSI board was more conservative with the default settings for that chipset.

Final suggestions for your particular motherboard:

I suggest you go with whatever stable FSB you can get within those parameters.
