The voltage increases to stress cpu (Prime95, IntelBurnTest, etc)

post #1 of 6
Thread Starter 
Hi all, I have a question.

I acquired to leave stable my OC to 3.90ghz (1.425v in BIOS), but it happens when I'm stressing the processor with IntelBurnTest or Prime95, the CPU-Z and HWiNFO64 tells me that the maximum peak processor voltage is 1.520v ... I wonder if this is good and if I could fix it.


The LLC I have it on 0%, so it is disabled, no?

My CPU is Phenom II 965 C3

Greetings.

you should set that at least to 50% or 75% to prevent the huge Voltage spike.

But it is assumed that the LLC does is increase the voltage under load, not?

I'm going mad, grrrr mad.gif

No. LLC is recommended. CTRL+F it in the guides. There's a very good post by a user here who has an avatar with a Skeleton in front of a computer with a pirate hat with a red sash. He had very detailed posts (pulling from anandtech's post i believe) which explained LLC.

didn't bookmark it but you do need a 60-80% LLC setting. For me it's normal high extreme or whatever. I followed sin0822's guide on ivy.

I do not understand ... in the link you've put me, comes this:



And the picture shows that if put LLC, I increase the voltage.

If enable LLC, I is stable even for a second ... : S that happens, I need 1.520v in BIOS to be stable or what?

If i put 1.425v in BIOS, CPU-Z in idle says 1.408v or less... this is vdrop, right?

Edit: Because of 'Vdrop', I just put in the BIOS 1.450v, with activated LLC (53%) and full load with IBT does not exceed 1.416v ... This means I can go further increasing vcore in BIOS, and what counts is what CPU-Z voltage tells me???

The vcore tell me the same vcore in idle and full load, 1.416v max.
