Hey All,

I am just getting started in Overclocking my PC.

i5 2500K
GA-Z68xp-UD3p
Noctua D14 Fan
Corsair Dominator 8Gb

I followed an online guide with much the same hardware as i have, and currently got it sitting at 4.5Ghz and its nice and stable.

Idles at around 36c
Load at 68-70c Using Prime 95

Where my concerns lie, is when looking at CPU-Z it shows my Vcore at 1.392v when Speedstep is working and 1.404v when its working at max.

Looking at others overclocks, it would appear my vcore is pretty high. I have brought it down to where it will remain stable. Any lower and BSOD.

other settings are:

CPU PLL Overvoltage - Enabled
Turbo Boost - Disabled
Multi-Steps Load Line - Level 5
CPU Vcore 1.385
QPI/VTT 1.270
CPU PLL 1.810
DRAM Voltage - 1.510

Where my system is stable at 4.5Ghz, should i be concerned by the VCore, or just leave it run as it is?

Many thanks
 
Sandybridge maximum safe voltages

Core Voltage - Not recommended too exceed 1.38v, doing so could kill the CPU, we therefor recommend a range of 1.325-1.350v if overclocking.
Memory Voltage - Intel recommend 1.50v plus/minus 5% which means upto 1.58v is the safe recommended limit. In our testing we have found 1.65v has caused no issues.
BCLK Base Clock - This is strictly a NO, anyone using base clock overclocking could/will cause damange to CPU/Mainboard. (Set manually to 100)
PLL Voltage - Do not exceed 1.9v!!

I suggest you take a read of this:

That does seem a little high.
 
Thanks for the reply, I had read that, but also read the update which states it is now safe to use anything upto 1.425v.

So, from my readings i am within limits, but right on them..
 
Cheers,

I am reading about Vdrop and VDroop and Multi Line Steps, VTT QPI etc, but not much really makes sense, hence just using someone elses settings.

As said i am content that its running fine, but why my Vcore is so high compared with the majority is what really baffles me!!

Chip from a batch not as good as others?
