lol?

Brian: I am going to transfer you over to the technical department and they will continue with the process.
Brian: Please hold.
we_kk_tor@hotmail.com: ok thx
Please wait while I transfer the chat to the best suited site operator.
You are now chatting with 'Dago'

and you really think he does lie for me, and states something he dont know anything about?

So I have my PLL set to 1.7, but is that a bad thing? Could undervolting it also somehow damage my hardware? I mean it seems to be just as stable at 1.7 as it was at 1.8.
post #153 of 185
the intel safe range for pll is 1.71-1.89, so set it to 1.71-1.72 if it give u better temps/stability

though I wonder the same thing, why would undervolting damage a hardware? Shouldnt it be better the lower volt it is, as long it is stable? If someone could explain why, Id be happy

what's everyone's VCCIO and PCH Voltage at? or anyone know the max for both? i found that raising both from stock to about 1.15 helped my stability a lot
post #155 of 185
Intel range says +/- 2-3% I think, but I dont know how safe intel is on the voltages, it maybe works @ 1.15v without any issues, though intel want to be safe so noone can blame them or something, I dont know

EDIT: I found this on a sandy bridge oc guide on xtremesystems.org

VCCIO: more commonly known at QPI/VTT voltage, this is the VTT voltage. Formally known as Processor Power for I/O it is the voltage for the integrated memory controller as well as the PCI-E controller. While Intel’s Maximum is 1.05 +/- 3% = 1.08v, you can go higher, much higher. I would recommend staying below 1.2v for 24/7 use

so it seems 1.15v is no problem @ all. I will try to raise that volt and see if I can lower my vcore a bit for 5/5.1ghz

EDIT 2: also found this for PCH volt

Even try increasing PCH voltage one notch, I found that increasing it a tiny bit may help BLCK in some instances. Make sure you don’t go over 1.1v for 24/7 use

Wow awesome, I needed that Vaio driver.

Thanks bro!

if its true that the p67 hardware bug was initially discovered by increasing pch voltage and simulating heavy load,lowering pch voltage may have the opposite effect-reducing stress.

i`ve lowered my pch voltage to 1.012 v,no data corruption and although all ports are filled,all drives are recognized.

Have a nice day.
That is NOT true.
The Intel spec does NOT say that that the Vcore is .025 to 1.52v.

All that it says is that the potential VID of a chip can be anywhere from .025 to 1.52. That does not mean that any chip ever will have a VID that low or that high.

People seem to grasp on to this number for some reason.


It is like saying that a tire that a company produces *could* have a recommended inflation of anywhere from 10 psi to 50 psi. That does not mean that your tire which has a recommended inflation of 30 psi is safe to inflate to 50.
