i7 860, These voltages safe?

post #1 of 30
Thread Starter 
Are these safe for 24/7 use at 3.8 with HT? First time overclocking the i7 860 and found these settings from a user on here from a week or so ago.

BCLK: 200
Multi: 20
Vcore: 1.35v
VTT: 1.35v
Ram: 1.60v (set to your rams specs)
PCH: 1.05v
PLL: 1.80v
PCIE: 104
QPI: 4.270 GT/s
MCH Strap: 1600 Mhz
CPU PWM Frequency : 849 Khz
VTT PWM Frequency: 634Khz

they all look good, but why is you pcie frequency at 104 lol

EDIT: you might have to adjust some of those, i just noticed you said they were someone else's settings. your chip may like more or even less voltage so it would be hard to tell without trying. my cpu is a voltage whore.
the only voltages i would adjust is the vcore and the ram voltage and maybe the pll and northbridge if it's not stable. set you fsb, multiplier, and ram and leave everything elso on auto.

I followed the guide and thats what it said. Should I just leave it at 100?

I know I have to adjust them to get it stable, was just seeing if those were safe to start off at.

What exactly are the max safe voltages and temp that the 860 can take?

Also, I know this is the cpu section I'm in, but is the EVGA P55 SLI the same as the EVGA p55 on the bio download? I can't find the sli version in the list.

Thanks! All updated. Anyone know where I can find the max cpu voltages though?

Leave the PCIe alone. It's not worth the risk and should be completely unnecessary for only a 200 BCLK.

Absolute max values:
vtt: 1.21v
vcore: 1.55v
vdimm: 1.65v

However, I believe the figures intel provide are under the assumption you are running with 1.5v memory. Higher voltage memory (1.6v in your case) will require higher vtt, voltage differential and all that technical gobbledegook

If your 1.35v is with LLC off it's perfectly safe 24/7.
