This platform is definitely more interesting toplay around with on terms of overclocking but certain aspects of overclocking itself can make things so complicated. A slight increase or decrease could mean instability. It's definitely sensitive to some voltage changes, more so than others. As someone stated adding a little vcore helps with increasing memory overclocking stability and messing around with vcca is kinda weird imho. I have had 4.5/4.6 stable for quite sometime now. Now I'm messing around with the cache(uncore) overclocking. It's amazing how much boost is there from overclocking the cache.

Totally agree with you, haven't had this much fun since my golden 3960X back in February 2012 :D

My 5960X might not be Golden but from what I can see it's not to bad compared to others and pared with my new G.Skill 3200 MHz CL16 memory it's quite fun to play with. Wish I only knew how to clock and tune memory and timings. I think my results are OK but I've got no clue to what is connected to what in the timings here, just winging it :confused: :rolleyes:

Actually you have a golden sample cause almost everyone I read about could only attain 4.5@a vcore of 1.4.
Are you under water?
Are you comfortable with that voltage?
@4.5-4.7 what voltages did you use to maintain stability?

Yes I'm using a very high-end water-cooling and I'm comfortable with these voltages, vcore are just a tad over Intel's max on their white paper.
4.7 GHz needs 1.31V, 4.6 GHz needs 1.28V and 4.5 GHz only needs 1.26V all stable in XTU, Realbench, FS etc. and several hours on BF4 . I don't do any other test with AVX than XTU and only the benchmark

I use Adaptive Vcore and changes Windows Power Setting to my needs. Balanced for browsing and light work which gives me a low vcore as the CPU downclocks and High Performance for gaming and ofc. benchmarks. :)

What are your temps like?
What is Intels max?
Are you running stock bios? Have you tried using the Asus software to OC? I find it actually does a great job.
My processor (5930K) requires similar voltages as yours to operate at those speeds. I think you should add valley to your testing as it is probably the best overall long term gaming stability tester in my book.
I find that having my pump running on low settings yield about 10-15(62-67c) more degrees in stress testing(valley), which is totally awesome in my book. These CPUs run so much cooler than the z87/97 counterparts.
Low rpm fans and 2 360 rads work well, my pc have never been this quiet. I do think though that my 290s are adding quite a bit of heat to my loop but everything is well below threshold levels so I'm happy.

First of all I'm not at all concerned about noise from this rig as I run a few in the same room. My temps are, well how can I say this, where I want them to be as my loop or loops if I've got GPU's on water too.
I use a Lian Li PC343-Extended version that takes two 360x60 mm and three 280x60 mm radiators without modding, I'm running with only two of each atm with CPU only in the loop. But I also got an Hailea water cooler which are adjustable, for 24/7 it's set at 22 C and it then kicks in whenever water temps goes up to 23.1 C to bring it down to 21.9 C.
So CPU temp at these settings never goes above 65 C under normal use like gaming and browsing.

Another thing I'm quite a fan of is QDC's as they let me change things around easy and fast without draining anything, when I get my 980 Classified with water-block it'll take me about half an hour to set it up with a dual loop.

I wanted a water chiller but don't know if it's really worth it. I love the qdcs, every portion of my loop that requires maintenance has em'...couldn't make water cooling any easier. I'll never build another loop without qdcs.

Let me put it this way, the water chiller is the single most satisfying water cooling component I've ever bought. It kept my SR-2 rig running WCG at 4.35 GHz during two summers and it now lets me push this 5960X to 4.9 GHz 1.45 vcore in benchmarks with water temp at 15 C (if I want it'll take it down to 4 C but I'm concerned about condensation at that temp)

And I totally agree on the QDC's, the only way to do good water cooling with interchangeable components no fuzz or leak-testing.
 
Testing Micron single side 4X4gb (Crucial Ballistix 2400) for max freq with tights primary and secondary settings and voltages sweet spots. Not too bad for 2400 retail non binning kit

I having problem finding what is stable I can run realbench for hours also Aida64 but i start up Linx or Prime95 for 2 minutes and ill get a reboot or a BSOD, What are people using to test a stable overclock becasue i'm starting to pull my hair out trying to find what speed i can get out of this thing, My good old x79 was so much more simple. Also the good old tick if she boots into windows with 1.3v testing 4.4Ghz and up to test if you have a good chip no longer works .

This was discussed a page or two back, follow the link to this post:
Personally, I would use RealBench for these CPUs and HCI MemTest for the RAM. Judging by what Raja has said, on these platforms, it is almost a necessity to test each individual component by itself, and not in a test that stresses multiples at once, like P95.
Keep in mind this is all hearsay, for I don't have the money for one of these glorious X99 platforms yet :(

Just World Community Grid distributed computing over here, as I have no time to bench. My BIOS usually catches really bad settings, and rarely does my PC BSOD or randomly reboot nowadays. I have found recently as I have been honing things in that it is possible for Windows to run fine but I get a few random program crashes, like yesterday/today, so I bumped my VCORE up to 1.29 from my last post/screenshot and testing now. The chip definitely seems to need high VCORE for memory overclocks, with stock memory settings I can get away with 1.25v VCORE at 4.3GHz.

Yer i know but using realbench my system is stable on 1.26v when i need 1.29v using Linx so just makes me think.
 
A lot of people are saying if real bench is stable then your system is stable for 99% of things a normal users uses it for.

So here we go 4.4Ghz on 1.23v i ran real bench for 4 hours over night not one problem i could even go lower i think on the voltage.

Also i tried 4.5Ghz on 1.25v which wasnt stable i could go higher on the voltage i think ill need around 1.26-1.27v for 4.5Ghz but its only 100mhz and ill rather the lower voltage.

@ Live OR Die
I believe you can go much lower on that OC, I'm at 1.19 vcore at 4.5 GHz
 
My chip won't do 4.5ghz on 1.2v ill try and see tonight , idle temps will be lower on adaptive or offset voltage.

It's almost summer time over here so temps will be higher, but those temps where also when using the high performance profile in windows so no down clocking also.

So after running my 4.4Ghz overclock on 1.23v i got a BSOD in BF4 lol even after running realbench for 4 hours, So i went back to my old tool LinX and going off how stable my system was using LinX for 4.4Ghz i needed 1.27+ voltage on the core, Becasue it nearing summer i didnt want to go over 1.25v so i back it down to 4.3Ghz which i got stable using LinX on 1.22v which i'm happy with for now, After 2 hours testing highest temp was 78c.

Got my memory up to 3200Mhz on 1.35v 15.18.18.36 which i didnt think it would handle seeing its only a 2800Mhz kit.

I have searched and couldn't find anything of the sort onto the topic at hand, so I wanna start by saying my stat is not validated only because I forgot to do so. CPU-Z screen shot necessary.

Do the following:
OC @what vcore
CPU
Mobo
Mem:Speed as well
HDD/SSD
Liquid cooling or Air? Type?

Mine:4.6 GHZ @1.28 auto-tuned, think I'm going to try and lower vcore to see if auto is being generous.
CPU-Intel 5820k
Mobo-Asus x99 Deluxe
Mem-G.Skill ddr4 4x4 2133-cl15-15-15-35
SSD-Samsung 240gb Evo
Liquid- custom made

I'll edit this post and post my CPU-Z when I get home.

OC: 4.6GHz * 8 cores @ 1.455V
CPU:5960x
Mobo: Asus R5E
Ram: Adata XPG Z1 4GB*2 @2800MHz cl16-16-16-39
SSD: Samsung 840 PRO 512GB
Cooling: Corsair H100i
 
New toy in the house to keep my CPU even cooler, LD V2

u got a really nice processor, man.
mine can only oc 4.4ghz when the core voltage is 1.4V :'(

You could go higher with an SS unit as the V2

I saw evap temps on the screen, but I am curious of DTS temps. I figure you're pulling about 275W or moer with that clock, so those evap temps are pretty good, IMHO. ONce I finish my certification I can buy gasses and will have my own unit up and running...can't be soon enough.
 
As long as I've got this SS unit here why not test what's the lowest vcore needed to boot 4.7 GHz which turned out to be 1.19 vcore set in bios with LLC set to level 1.
