Re: 3570K stock voltages?
That sounds ok to me. Stock voltage varies slightly for each motherboard (AFAIK).
Are you running it at stock speeds? i.e. no overclock?
If so, I would change it to 'FIXED mode' and set the voltage to 1.200V. Then run a quick stress test (i.e. Prime 95) to check that its stable.
You might be able to drop the voltage to around 1.100V (stress test to check), which will lower your power usage, but (based on the results with my 3770k) anything lower than 1.100V makes little or no difference to power usage or temps.
Re: 3570K stock voltages?
Thanks for the reply... It seems the voltage doesn't drop when idle in 'FIXED Mode' :undecided. I'm not doing any overclocking (H67 chipset).
Re: 3570K stock voltages?
Well over at Anandtech they showed that you can run at stock on 0.9v and that this does help with temperatures and presumably power.

You may get different results of course.

Is the CPU voltage already set/coded in the motherboards bios, or does it retrieve this info from the actual CPU?
Re: 3570K stock voltages?
I think the MB makes a best guess at what the CPU needs, although obviously it will play safe, very safe in some cases.
When I added a mild overclock to my CPU the MB decided to add extra voltage which it just didn't need.
Re: 3570K stock voltages?
As far as I'm aware, different chips will have slightly different stock voltages, all within the VID of the chip.
Here's a relatively simple explanation: (also the first link I found :P)

Intel changed the solder for Ivy Bridge, which (apparently) changed the thermal characteristics of the CPU. Rumor has it that it is either due to the brittle nature of the new Tri-gate transistor, or to make Haswell (the next generation of Intel Core CPUs) look better on release.
