Correct voltage????

[Uncle Vinnie]

I just overclocked my Athlon x2 4600 from 2.6GHz to 2.7Ghz.
The voltage that I have setup on the bios is 1.45V, on Asus AiBooster it also shows 1.45V
However on CPU-Z it shows 1.376V.
What is the correct voltage that the CPU is using?????

When the CPU was running at 2.6GHz, idle: 32C, load: 50C
Now at 2.7GHZ, idle: 35C, load: 53C

This is of course with air cooling, I have the Thermaltake Blue Orb.
Am I pushing the Temp. a little to high on the CPU, or is it still safe???

Thanks

Setting it in bios allows a maximum to be supplied. The amount 'drawn' depends an a lot of things like how hard the cpu is working and wether or not you have 'cool-n-quiet' engaged.
Also a measurement within 5% of value is considered accurate. Therefore 1.45 - 5% = 1.3775, rounded up thats right on the money.

But how come when I set 1.45v vcore and in 100% load the vcore DECREASES not increases.

That could depend on a lot of factors, how much of your available power is being sucked up by the GPU, northbridge, memory, ETC. It's basically all up to your particular mobo and the parts you have combined it with. Another symptom is that your PSU may not realy be supplying enough power(amps) so when you up the vcore it's ok, but when you load the system they voltages drop because the PSU can't keep up with the demand.

Remember 20 amps to much only cost money, but 1 amp not enough and your rig don't run right.

I shouldn't worry about it too much. My Celeron cpu on a new system I'm working on reads a different Vcore in CPUz to the BIOS. I also find a drop of about 0.04V when applying full load!

However, I really don't care what the exact Vcore is. I just need to know how much extra I'm pumping into the little chip. The most important thing in OCing is that your Vcore is stable, mine fluctates by approx 0.01V under full load over 7-8hrs.

Hence I've OC'd my Celeron 331 from 2.66 to 4.2ghz. And that's on air cooling using only the stock HSF and TIM. Fully Prime95 stable overnight.
