Maximum save vcore for 3800 x2 overclock on air?

Maximum safe vcore for 3800 x2 overclock on air?

As per the title... my rather rubbish (OC-wise) new 3800 X2 seems to need quite a bit extra on the vcore front to overclock. I've got 2350MHz on 1.475 vcore, but 2400 won't happen on 1.5 volts -dare I go any higher using an AC Freezer 64?

Depends on temperatures. I'd say 1.55 if it isnt too hot.

Well, at 1.5 vcore my load temps at 2400MHz were about 42 degrees, I've got excellent airflow across the AC 64 thanks to the CM Stacker (120mm in, 120mm out straight across the CPU socket).

How hot is too hot?

Try to keep it below 50.

OK, thanks for the info. I've never pushed the vcore before, although I've overclocked every CPU I've owned. 2.4GHz out of this one would make me happy, basically a bargain 4600...

I think I'm heading to the limit, as the jump from 2350 to 2400 seems to want quite a bit, shame really as others have done much better on less volts, just my luck!

I had my X2 3800 at 1.61V for a quick burn in. I also ran a 3000+ at 1.65V for a year with no issues. It's a lot about how good your cooling is and what your temps are at. You take a risk with volts that high so be warned. There's a good chance your PC will reboot/lock up before any permanent damage is done but it's not always the case.

You can look here for ideas and to see what other people have done. Personally, I wouldn't go past 1.55 on air.

I found with my first one that once it hit a certain point, it needed quite a lot more volts for a little extra speed.

Mine hit 2750 at stock volts but needed 1.5 to hit 2850 and 1.55 to hit 2950. I tried it up as far as 1.7V but couldn't hit the magical 3000 on air. It runs stable at 2800 at 1.475V.

Personally, I would be wary of anything over 1.55 long term.

Not pushed my second one yet due to crap, cheapo mobo but Ultra D ordered

No more than 1.65v for AMD dual core. < From AMD.

ACENESS !


Im going to go see if i can get my 4400 Stable @ 2.8 Ghz now


EDIT : I have been using 1.5 volts max, because people were saying 1.6 volts could kill the chip, but with sufficient cooling i can't see it being a problem

1.65 volts! Blimey, I'll see hpow I go...

Quick question - my BIOS is set to 1.475 vcore, reporting 1.44, CPU-Z reporting 1.44, which is correct?
