Light ci7 3930K overclock ?

Gripen90 · 26 Jun 2014 at 02:40

I haven't been into the overclocking thing of CPU's for years (last time I OC'ed was a XP1800+ 1533@2560MHz), but now I thought I could be nice just to get a bit more "juice" out of the 3930K (to post pone the X99 purchase a bit), but I'm not looking for going to extremes.

My goal is something between 4.2~4.4GHz if that can be done fairly "easy" and with not too much hassle with settings. ?
I have seen videos on youtube for X79 overclocking but many are going way beyond what I am looking for.

I have though of these setting if that will do
CPU Core ratio = 43 (for 4300MHz)
CPU Voltage Offset = + 0.156
(normal is 1.100 so should hit 1.256v core)
I haven't thinking of touching any thing else. :rolleyes:

I had though of just using Asus AI Suite II software and run Auto Tuning, but I hear people say it's better doing even just a small OC via the BIOS.

I am using an Asus P9X79 Pro, 16GB 1600MHz CL8 Ram, Core i7 3930K C2 stepping, Arctic Freezer i30 CPU cooler.

You are on the right track.
up to 4.4 is easy.

Just increase multi to 4.3 and use a bit of positive offset.
Do it in the BIOS, I personally wouldn't bother with useless bloat such as AI suite.

Also
If your planning on running any heavy apps the i30 you have is not going to be good enough beyond 4.3

I tried multiplier 43 and tried voltage offset settings from 0.015 to 0.040 and Auto.
But I would get BSOD, freezes and more and now my windows won't start any more

You had the voltage too low.

Gripen90 · 26 Jun 2014 at 13:25

But the voltage i had it to was 1.40 ... shouldn't that be enough ?

I run OCCT and it reports error after a few seconds.

tried multiplier 43 and tried voltage offset settings from 0.015 to 0.040
that wouldn't give you 1.4v unless auto did.

Auto is off. I even tried to manually set 1.35v for 4.3ghz. But i only got Windows black screen.

Gripen90 · 26 Jun 2014 at 14:26

Screw it. Even at 4ghz. Voltage auto (gives 1.312v) it crashes.

Something else is wrong.
No CPU is that bad.

As a quick test reduce your memory speed to 1333 and try again.

I tried asus ai suite 2 fast oc. It also crashed and bsod at 4054mhz and 125mhz blck and 1334mhz ram settings.
I am screwing this and going stock again. I have tried ocing for 5 hrs now with no luck.

Only when running 1.425 vcore at 4 to 4.3GHz it seems stable.

I have tried lowering command timing 2t instead of 1t at cl8-8-8-24 timings at 1600mhz. Did not help.

I'm not sure OCCT is working properly. Even at stock speed it stopped the test saying core 1 had reached 176ºc...even though HWmonitor showed it no higher than 58ºc.

I guess my luck with OCing is over.

Gripen90 · 26 Jun 2014 at 17:56

Bahh I'm OC'ing my GFX's instead

Follow this guide.

Your Cpu can't be that bad.

Don't give up so easy, follow the guide, it is something simple your missing that is all, promise

Gripen90 · 26 Jun 2014 at 19:28

I have given up. It should not be that complicated when other i talked to just upped the multiplier and set voltage to auto and then nothing else...and theirs have been stable at 4.2ghz.
Mines not even at 4ghz and auto voltage.

My GPU oc on the other hand is succesfull.

Gripen90 · 26 Jun 2014 at 22:12

I have tried this so far.

1) multiplier 43, voltage offset + 0.040. OCCT gives core error and the pc bsod.

2) multiplier 43, voltage manual 1.350. Windows will not boot and crashes.

3) multiplier 43, voltage off set + 0.060v. OCCT runs but cpuz show the core voltage is 1.432v ... and the cpu is running hot in the 70ties.

4) multiplier 41, voltage offset + 0.030v, lowered ram command timing from 1 to 2t. OCCT reports core error.

5) multiplier 40. Voltage offset auto. Cpuz shows 1.312v core. Trying to run OCCT and getting bsod.

6) Tried running asus ai suite 2 Fast auto tuning. PC bsod at 4049mhz, 125blck, 1334mhz ram.

Right now I am back to stock settings... but OCCT is acting up. I reports core 1 hitting 176ºc and then stops the load testing - however hwmonitor shows it max hit 58ºc.

Starting to wonder if it's because I'm running 3 way SLi at pci-e 3.0 that puts stress on the cpu making it fail to OC ?

scotsdragon · 27 Jun 2014 at 00:57

Have you tried clocking on different strap I have mine oc'ed on the 125 strap its a lot more stable than multiplyer?

I tried 125blck strap and 32 multiplier and auto voltage... still BSOD's.

I'm giving up on it. This CPU isn't ment for low voltage. The previous owner had it at 4.9GHz at 1.52v stable on an asus x79 sabertooth - it's just a voltage hog this cpu.

I just OC'ed my 2 other 780 from 863Mhz to 941mhz instead to match my evga 780SC... that brought a little performance increase.

That explains why it is such a bad clocker.
Think yourself fortunate it is still running at stock.

CPU's degrade at high voltages, and the previous owner treated the CPU very badly.
