Voltages for ClawHammer ?

[Zenoth]

Hey.

If I am not mistaken, the default voltage for a 130nm ClawHammer is 1.5v.

Well, right now mine is over-clocked at 2.4 Ghz, only a 200 Mhz bump. Currently, voltage is 1.525, and is Prime stable (ran torture test for 18 hours without problems).

I was wondering though ... since I paid that A64 CH 3500+ very cheap as an X2 4400+ replacement (my 4400+ was recently doomed by bent pins and decreased performance, I'm waiting for my new one to arrive at my local store), I could perhaps bump it to 2.6 Ghz.

Should I increase the voltage if I do so ?

Oh, and the FSB is 240 Mhz, with a 10x multiplier.

I guess I could try 248 x 10.5, to reach 2604 Mhz. But at which "safe" voltage ? I'm asking because I don't feel like waiting 18 hours and more, for another stability test. 1.550, 1.575 ? Only a few suggestions would give me ideas as to where I should try to set it at. And I've read the A8N-SLi Premium have problems with FSB's at 250 Mhz+, but I'm not sure about that.

Thanks.

Yes the default voltage is 1.5v. My best result with a Clawhammer 3500+ was to run the voltage down instead of up. Reason was that the cpu would go ballistically hot with any increase in voltage above 1.54. I figured this out the hard way because my conventional wisdom was always to raise voltage for higher OC. I was always erroring in Prime, etc.. because heat would take it out. Once I lowered the voltage the OC started coming up and the cpu ran alot cooler. Eventually you have to raise voltage though so it's a catch22. I landed at 1.48v @ 2.5 GHz @ 58C load. By far this was the hootest running cpu I ever saw and was glad to have only used it for a couple of days. With extreme cooling, 2.8 may be achievable....
