Is 1.5v safe for a 4400+?

[MR.B]

Is it? I think i'm going to have to have mine at 1.5v to get 2.8ghz.
I'm on water cooling so my temps are always low, never past 41c at 2.6ghz.

And when i set 1.5v in the BIOS it always reports for core voltage that its lower, like 1.46v or something. So i'm going to have to put it at about 1.55v so that it's at 1.5v. Is this normal for it to be lower than i set? (specs in sig)

Thanks

Ok i set it to 1.55v, and BIOS and software said it was 1.49v.
Then i increased the FSB to 11x246 (2.7ghz) and i run 3Dmark06, it was finally stable... BUT i got a lower score, not just a bit lower but 1K lower! so ran some other benchmarks and everything was a lot lower... wtf??

CPU temp was about 43c under load so it aint overheating.... could it be my motherboard chipset though because that gets up to 67c...

More likely that those temps are the other way around... what are you using to report the temps? 43c under load is nothing, almost idle temperature. 67c load for a CPU is more realistic if its air-cooled and overclocked.

Could the BIOS be pulling back on the overclock too? Doesn't it have that thermal thing built in? (I'm an Intel P4 man )

I have water cooling, thats why my CPU temp is that low dont have the chipset water cooled though. I think it was over heating because if i take the case side off and have air blowing in it, i score higher.
So i guess it's the chipset, or something on the motherbaord getting too hot..

I've got an A8Nsli-p & it will only push 1.50v through the CPU but reports this as being 1.55v.
With a load of fans & reserator it will do 2.75 but I prefer the quiet so run fanless at 2.6, idle 40c / load 55c.
The mobo temp which I think regulates the power to the CPU always runs hotter until the CPU passes 50c.
If you're running slower now you've upped the FSB then probably your RAM is running on a divider as in its not running at your FSB speed.
You'll get the best speed by running the RAM as fast as it can then adjusting the multiplyer to give a stable CPU speed. Lower RAM timmings maybe better than frequency though -mines running 1T which really improves everything. Then you need check your HT multiplyer. Best to be booting up at DDR400

I was on a 9/10 memory divider at 2.7ghz, but i also was before at 2.6ghz. My RAM cant do 1:1 timing at anything past 220FSB. As i just said above i think something on the board is getting too hot
I think i'll stay at 2.6ghz, it takes too much effort and voltage to run just 100mhz higher.
