what's a safe voltage to take this CPU to? i'm getting some reboots when oc'ed at 3.0ghz with 250mhz FSB running at default voltage (1.60? i'm not even sure).

could it also be a lack of power from the PSU? it's an Antec 380w that came with the Sonata. if it was overheat, i'd think that it freezes instead of reboots.

memory is Kingston HyperX PC4000, 2 sticks of 512 each.

want to be able to keep it at 3.0ghz.

Both the 3.0GHz (D1 stepping) and 3.2GHz default vcore is 1.550. When I took my 2.4C to 3.4GHz, I was at a vcore of 1.66 (according to Asus Probe - can't remember what I put it at in BIOS).

If raising your vcore doesn't help, look your RAM voltages. Your sticks may need some more juice.

Generally bumping the VCore on the O4C's doesn't help that much (unlike the older socket A Athlons).

I personally saw no increase in overclocking headroom even with my voltage up to 1.7V.

[quote="cigar3tte"]what's a safe voltage to take this CPU to?/quote]

I'd say 1.6 is safe. My 2.4C makes it to 3.2 on stock voltage but my 2.4B don't overclock to ANYTHING unless I up the volts. I'm running 1.6 on a 2.4B and it's mighty fine. It was 1.575 but that wasn't enough. I'd try not to blow past 1.6. If you *need* to it may not be worth it. Still... a clean 3GHz feels like sex. :P

What board are you using? I had also gotten some Kingston PC4000 memery and tried using it with my Asus P4P800 board. It didn't like anything above 225mhz fsb. I sent it back and got some OCZ PC3700EL stuff. I'm running at a 275mhz fsb with a VCore of 1.6.

Makes me happy to see OCZ getting more widespread love these days. When I first started playing with their enthusiast line, it was a challenge at Delphi getting people to realize their reputation for 'hit or miss' is no longer accurate.

I got to 3.12GHz @ stock voltage.

Increasing the voltage didn't help at all.
