3930k overclock

Last response: in CPUs

I am looking to overclock my 3930k to 4GHz. I want to try and do this without raising the voltage above Intel's recommended 1.650 volts, (due to high price of processor, and I want it to last till Ivy Bridge-E releases.) I also want to be able to operate it 24/7 at this clock speed, so I'm not constantly changing things and mess up. Can anyone help me since I'm a Noob to OC'ing?

Specs:
3930k
H80 cooler
Asus Sabertooth x79
Kingston HyperX 1600MHz 2GBx8
Radeon 7850 1GHz
Samsung 830 Series 128GB
Hatachi 1TB 7200 RPM
Seagate 400GB 7200 RPM
Antec 750 watt PSU
Antec Twelve Hundred V3

I have taken my 3930k to 4.2 ghz on the stock voltage with my intel water cooler (about the equivalent of your h80, maybe a little lower), you should be able to do fine on 4ghz. Just crank it up (don't touch the voltage) and run intel stress test, if you can keep it running for say, 12 hours (best to do for 24hrs) you should be set! If you do crash or blue screen, take the voltage up a little and try again. but once again, I think you should be able to do fine without touching the voltage.

The turbo for the Intel® Core™ i7-3930K is already at 3.8GHz without any voltage increase I would think you could hit 4GHz very easy with that processor. Heck I would be shocked if you couldnt hit 4+GHz with the air cooler that we offer for that processor.

Intel's recommended 1.650 volts ?????

surely thats for the ram dont put 1.65v through the cpu

Whoops meant 1.350 volts, thanks for that :)

heres a guide to overclock it

main things dont go crazy with the voltage and keep an eye on the temperatures

as already said 4ghz should be simple

with an h80 i would think 4.4ghz to 4.6ghz should be a reasonable point to aim for

You should be able to hit 4Ghz quite easily just by bumping the turbo multiplier and leaving vcore on auto. I'm not sure if the Sabertooth has the ability to run all cores at the same max turbo bin like the Rampage IV Extreme does though. It should go somewhere aroud 1.3-1.32 volts on its own at most. Keep in mind that the 3930k has half again as many IA cores and cache, two and a half times as many PCIe lanes and twice as many memory lanes. This adds up to almost twice the power output as an equivalently clocked Sandybridge-2000 series processor.

At 4Ghz your CPU alone will be pulling over 200 watts under Intel burn test conditions and an H80 can have trouble cooling this. Do not be surprised if the IA cores hit 90 degrees and start throttling themselves, this is normal.

I was trying to be conservative and put mine at 4.2. Last night I did that and bumped up the overdrive in Catalyst Control Center, I swear my computer had a hissy fit on me.

I turned everything down, took off overdrive and have had the cpu at 4.2 since last night, working fine for now. Been checking it randomly though seems to be fine. The bios I have makes overclocking easy, but I am keeping it at this till I know it works fine.

Thanks for that extra assurance.

Hey there...I run mine at 4.6GHZ to be safe as far as sustained durability. But I have ran it at 5GHZ with the Core V @ 1.55...It was FAST AS SHIP!!! Anyways now it sits at 1.35 to 1.4 @ 4.6GHZ... My setup is as follows:

INTEL DX79SI MOTHERBOARD (AWESOME OVERCLOCKING ASSISTANT AND STABLE AS HELL)
3930K CPU
32 GB CORSAIR VENGENCE RAM--1600
128 CRUICAL M4 SSD @ 6GB PER SEC. TRANSFER
INTER LIQUID HEATSINK N RADIATOR
EVGA NVIDIA GTX 650

I run a 3930 at 4.4 with a pretty much standard heat sink. I have not touched the voltage at all but system is very stable.

Any one have a safe voltage suggestion without water cooling?

What should be my first, baby step increase?
