Overclocking i7-4930k Help

Just installed my 4930k today on an EVGA x79 Dark. Took the multiplier to x47 and the VCore to 1.5V. Enabled PLL Overvoltage and changed the PLL voltage to 1.6 and the VCore VDroop to "Intel SPEC" which means 100%

I get blue screens. All of the BSOD codes, as i slowly increased the VCore, were 0x0124 except one was 0x0C2.

I got up to 1.55v on the Vcore and I was like okay I give up, lowered the multipler to x46 and put the VCore @ 1.42v... more 0x0124 blue screens... slowly increased VCore until I got back up to 1.5V and now its not crashing after a few minutes of LinX and P95.

So is this a really bad chip or is there something in the settings that I'm missing/doing incorrectly? 1.5V just for 4.6GHz? I'm going to be running 20 runs of LinX all afternoon to test this clock..

Have you seen the reviews? PCPER couldn't get the 4930K passed 4.3GHz, OverclockersClub couldn't pass 4.44GHz, HardwareCanucks couldn't pass 4.55GHz etc.

While I am not saying it's impossible to pass 4.6, I presume you just got an "average" chip.

I have my 4930K sitting here on my desk, but I don't have a board to try it in and I won't until the RIVE BE comes out. Sorry mate

1.5v is very high for 22nm Intel parts. 1.4v load is about as far as SB-E can be taken, 24/7, on air or water and they were 32nm.

Most 4930ks aren't hitting more than 4.5GHz stable, and you probably shouldn't be using more than about 1.35v, 24/7.

Sounds about right voltage wise, even with these crazy volts my highest load core has only been 66C in a custom prime test. This chip is cool though, compared to Sandy-E.

I need around 1.45v for 4.5 on my 4930k in a Rampage IV, just like you nothing but x124 BSOD's otherwise.

Maybe try using straps to overclock, but I'm hoping in time we both will get a better bios. These chips did just launch after all.

Guess I'll keep it at 4.5GHz @ 1.4V. Thanks for the help.

Yep they seem to clock poorly, mine does 4.5Ghz 1.40v, 4.6Ghz not even at 1.46v.

Exact same BSODs as you.

I found that loosening RAM timings helped, i cannot do 2133Mhz 10-10-11-29-1T on the 4960X even with VCCSA at 1.2v. Whereas the 3960x took 1.1v VCCSA and wasnt even pushing it really.

Very weird. I thought ib-e brought a much improved Imc. My 3960x won't budge over 1600 @ 4.7 no matter what vssca/vtt I use.

My System:

CPU: 4930k
MB: Gigabyte ga x79 UP4
Air Cooling: Noctua nh d14 + Fractal Design Arc midi2 case
freq: 4.2 Ghz
Volts: 1.4V (no Offset) with a little Increase in PLL and VCCSA, no Memory-OC. Load Calibration is at "Turbo" (80%)
Temperature are max 78°C under IntelBurnTest and ~ 40°C on idle.

Iam not able to run my 4930k at 4.2Ghz under 1.4V
No POST whenever i go over 4.3GHZ (i tried only up to 1.45 Vcore)

My CPU doesnt seem to be a good one.

Well these settings are used as a starting settings for liquid nitrogen, after someone tested the CPU to know its engineering limits. Have you really started with these? And you still have your CPU?

4930k is a poor overclocker indeed. Oh well, I'm only waiting for an 8-core Haswell-E. Until then this is will do just fine

The funny thing is is that my 4930k @ stock clocks was putting out the same 3dm11 physics score as my 3770k was @ 4.9GHz

defenitely is a better CPU overrall man lol it cost twice as much... in the other hand... bro do some video recroding on youtube... learn how to setup the MSI afterburner to show the FP
and GPU usage please...

other than that... i envy u man... that a nice CPU!

Yeah I knew how to do it at one time but was a long time ago and I forgot.

Yes I'm well aware of the differences in the two CPU's, I was just putting it into perspective.

And thus, I finally got a *stable* clock on my 4930k @ 4.5GHz 1.4V I'll also run 14 hours of Prime95 over the weekend just to be sure.

Maybe you just have too high expectations?

I noticed the exact same thing when going from 3770k to 3930k.

after installing the 4930k, I can't run 3dmark anymore. I get a gui failed to run error.

If you can crank at 4.5 GHz at 1.4v, I'd say you got a decent 4930K. I certainly wouldn't run it higher than 1.4, and if it were MY chip I wouldn't exceed 1.35v. The smaller the junctions, the lower the voltage it takes to end up with electron migration, and that's always bad. With 22nm cores, I wouldn't be surprised to see long-term damage at 1.4v begin to settle in after a matter of weeks. Still too new to say for sure, but you're a Week 1 buyer and we need somebody to do the risky experimentation for us. =)

Gratz on the 4.5 ant 4930K!

The problem is your motherboard, i have a friend who has the same board and can only get 4.3ghz at around the same voltage as yourself. We tried the chip in my Rampage Extreme IV and got it too around 4.8Ghz on 1.45v. if you have read about there are plenty of people struggling with the UD4.

Ivy Bridge Architecture isn't as great overclocking as Sandy Bridge if you look at the 2700k v 3770k it was exactly the same as 3930k v 4930k it's a trade off lower clock speed but more speed clock for clock..

Just about right, except temperature is much better on Ivy Bridge e . For the week I owned a 3930k, at stock speeds with an Evo 212 cooler, the 4930 runs 7-10C cooler. Other than that it is exactly as you said.

Just overclocked my 4930k to 4.5Ghz with 1.25v(bios), booted fine on windows. Intel Burn Test did fail(didn't crash) on it (cpu-z showed 1.23v on load). Increased voltage to 1.27v in windows. Now it manages to complete IBT (cpu-z showing 1.25v on load). 80c peak temps in about ~28c airflow.

Going to test more and increase it up to 1.3v if needed, but going to leave it like this for now and check back when someone has optimized it : )

My settings:

Rampage IV Formula + Noctua NH-D14 + 2133Mhz 4x4GB ram

Used XMP profile
CPU ratio 45
CPU voltage 1.27-1.3v
CPU PLL 1.8v
CPU VCCSA and VTT CPU 1.1v
Disabled every powersaving feature I could find.
Disabled intel adaptive thermal monitor.
Disabled Anti Surge Support.

DIGI+:
CPU LLC - Medium
CPU Current Capability 120%-130% ... seems like if you put it to 130%, the phase control is locked to extreme.
VCCSA LLC - Regular
VCCSA Current Capability - 120%
DRAM-AB/CD Current Capability - 120%
DRAM-AB/CD Phase Control - Optimized
VRM Over Temperature Protection - Disabled
CPU Power Phase Control - Optimized. Did read something about having it manual when you use manual cpu voltage like I am.
CPU Power Duty Control - T.Probe

My batch number: 3326B662

Restarts done: 1. Crashes 0.

Update:
Raised CPU voltage to 1.29v (cpu-z 1.26-1.27v on load) to pass Prime95.
