Overclocking 4930K on a Gigabyte X79-UP4 with bios v.7

[spaceprowler]

Does anyone out there have this combo and have a stable OC of around 4.4-4.6ghz ? I have tried so many different ways to get this chip to at least 4.4ghz but I cannot go past 4.2ghz and that is with a lot of vCore.
I have 16gb of G.Skill 1866 ram @ 8-9-9-24 XMP profile. I have a Rosewill 1300w Gold PSU with 2x GTX-680's in SLI and a few SSD's in there. My CPU cooler is a Corsair H100i and even at 4.2ghz with 1.4v , my CPU never goes past 67c. I am doing something wrong in this new bios and settings and it is driving me nuts !!!
Anyone have stable OC out there with similar setup ????

I don't have an Ivybridge-E but I am just about to pull the trigger on a 4820K and x79 combo, in advance I have done a lot of research into overclocking them, a number of things came up which seemed commonplace across all these cpu's on the x79 platform, if my memory serves me correctly a number of users were advising not to run memory on it's XMP profile, might I suggest giving that a try first to see if it helps (put the timings on auto at first), if it does you can always tweak it afterwards.

How are you overclocking? Are you just touching the multiplier? I don't have an IVB-E chip, but my 3820 doesn't really like to go over 4.2Ghz without dumping more than 1.3v into it. Since the 3820 isn't fully unlocked, I tend to use a 125Mhz BCLK strap to achieve 4.5Ghz, but at that point I'm dumping 1.4v and anything north of that needs more voltage. Have you adjusted your VCCSA voltage along with your vcore? I try to keep it 0.2v lower than my core and my VTT is usually at a steady 1.2v but I usually only need that for 2333Mhz memory where 1.15v is fine for 2133 @ 9-11-10-28.

So I guess my question is, where is your VCCSA and VTT voltages at?

XMP is only a problem with 2400 MHz+, and with mixed kits, and some 8 GB DIMMs.

32 GB or less, 2133 MHz is best optimized as suggested by Aquinus.

I personally feel that 1866 memory divider is broken, too.

Did you try increasing the LLC a little and changing current allowance because that might be limiting you. Otherwise might just have a really bad chip or you need a newer BIOS.

I don't really think you should go too gung-ho on LLC. You really should adjust it for any Vdroop you may encounter that throws your OC off. Setting it too high can cause the VRMs to overshoot the voltage when load changes if you crank it too high with too high of a voltage. It's best to air on the side of caution with LLC imho. Too much Vdroop is safer for your CPU than an unstable overclock caused by it (while you're getting the overclock right, instability when you're doing something is never good) but voltage spikes are never a good thing, OC or not.

There could be a turbo current limit that might be impacting his OC, but I've never encountered it with my setup. Granted I don't have the same motherboard.

I tried that... even dropped my ram speed to 1600mhz and did all settings manually .... same result .... vdroops....loadline calibrations... power phases ..... even tried with higher blck of 105 instead of the base
of 100.... instant BSOD or freeze. Coming from my last setup a I7-980 on a Gigabyte X58-UD5 mobo on air I could get that chip to 4.4ghz on AIR. This bios is way different and most of the reviews
and settings for this board they were using the 3930K chip. This chip and board should do 4.4 easily but it is NOT !!!! LOL
And the voltage is pretty high tho I have read that even on ASUS boards this chip will require the xtra vcore, but 1.4v for 4.2ghz cannot be right !!!!

I have a similar chip, some chips are just that way. What you can try is custom turbo settings, with higher multi on less cores active.

I'd like to know what your stock voltage is.

Bios is new version....F7 .... and I did try changing LLC but no luck with that ! I am thinking it is just a weak board .... they say 80% of these chips will do 4.4 and the other 20% can hit 4.8-4.9ghz.
Just very difficult to find someone with an identical mobo and chip ! Like I said...most posts on this people are using the 3930k !

I did try ( in fact I am running it now with multi on 34 and turbo at 41 ) and it is running at 4.1ghz with 1.375v .
My stock voltage on default is .990 - 1.24v or so depending on load ( all settings on auto ).
Some say leave turbo on on Ivy Bridge E and some say disable it, usually I leave it disable and lust go with
blck & multi settings.

I believe I had it ( with failed results ) at VCC at 1.3v and VTT at 1.180.
I keep reading don't bother with BLCK strap tho I have ... and use multi x base clock of 100 and adjust voltages and vdroop and bump up just a couple other settings..... but just not happening !
4.2 runs beautiful and cool even with high vcore of 1.4v, after that.....gets unstable...mainly prime95, it usually will pass Intel Burn test and OCCT and AIDA64 stability tests.... 5 minutes of Prime and
I'm done !!!!!

drop vccsa to 0.95V or so if possible, it's more for memory, so if you don't need it that high.. don't.

0.990V for idle is rather high, sounds right for a poopy chip. Sorry about your luck.

See I really doubt that as the VRM is a 8 phase IR design it should OC just fine when using aircooling especially considering how low power a Ivy E chip is in comparison to any Sandy E chip.

My stock voltage on default is .990 - 1.24v or so depending on load ( all settings on auto ).

Your stock voltage is waaaay too high 1.3V is what most Ivy e chips need for more than 4.5Ghz so your chips is just really really bad.
