Overclocking "Mr Glass"

Hello there

Some of you fine chaps and chapesses were kind and patient enough with me a while back when I was having some problems with my X99 based build. Thankfully I got my X99 Deluxe RMA'd and have a new one, and have started the process over again. I thought I would share my findings and quite probably seek your help again :D This processor seems a little bit fragile TBH and gets scared above 4.2-ish GHz, so I would like everyone to help encourage him to his best :) If you must be "overclocker-veteran-grumpy" then please add a lolcat or something to your grumble, to take the edge off lol

SPECS:

5820K
X99 DELUXE (BIOS 1103, latest one)
16GB CORSAIR Dominator Platinum 2666MHz (running at 2133 for now)
2 x 980GTX EVGA SC ACX 2.0
H105 cooler
A bunch of SP120 fans and one AF140 in an H440 case
1000W Superflower Leadex Platinum (Power reqs calculated at 770W with everything at 100% max)
Samsung 850 Pro SSD 512GB
WD Caviar Black 2TB

So I started off at 3.8GHz and a fairly high voltage of 1.28V. It was nice and stable in AIDA64 (I know, its not very challenging) and ROG Realbench. I am steering clear of Prime 95 and OCCT as frankly they scare the crap out of me and I have a suspicion it may have exacerbated my last board's problems (I didnt use linpack though, it was the other one and pushed my temps to mid-80's)

Then I pushed the multi up to 4.0GHz, again stable with above parameters.

Then I got cocky :) Multi to 43, voltage (VCore) to 1.28. AIDA was happy but Realbench just laughed. I decided to make just a 15 minute RB test my goal for now, so I tried:

VCore to 1.3V, not a lot of difference
VCCIN to 2V - alone, gave a couple of extra mins in RB but still blue screen
Cache Multi to 40 + Cache voltage to 1.28V, passed the 15 minute RB test. Small celebration.

Temps in RB are around 60 degrees.

Final settings for tonight:
VCore: 1.3V (yellow in BIOS)
VCCIN: 2.0V (purple in BIOS)
Cache Multi: 40
VCache: 1.28V (yellow in BIOS)

Ideally I don't like that VCCIN and would rather have not had to up the cache, though I have found a number of reviews that stated they needed similar values. So again, mine doesn't look like the best clocker out there, but it has passed a little hurdle tonight :) There's a ton of other settings that confuse the life of me in that Deluxe, so I think the next goal will be 45 minutes in RealBench!

I'm not an x99 expert but it seems to me that 1.3v vcore is at the upper end, I'd aim for keeping it at or below 1.28v, if you can run 4.2ghz with this it would be good. That extra 100 mhz won't matter anyway.

I run at 4.25GHz @ 1.26v for my core, ring is at 3.5GHz @ 1.32v, and my RAM is at 2666 cl14, 1.25v main and 0.625v termination voltage. It is impossible to get the uncore/ring above 3.6GHz without an OC socket, so don't be frustrated if can only get 3.5 out of it, as the voltage can only be properly raised by the $500 ASUS Rampage or whatever board. Base clock is set to 125MHz.

EDIT: Never mind, your board has the cool socket, you can probably get higher clocks, but I think much beyond 1.3v enters territory for high enough chip current when pushed hard enough to cause damage.
