So... I can do 4.6ghz at 1.32v on my 3770k... and I was trying to get to 4.8ghz with 1.40v and was not able to do it at all. It totally escaped my mind to check temperatures. I'm using a water set up, and I knew that temperatures would be bad... but not as bad as I am seeing right now.

Perhaps reseat and all that good stuff.

Nice thumb.gif My temps are a lot lower than they were before so I'm really happy with where they're at now, and would like to improve them but I'm not sure how much more I'll gain. I'm out of the Liquid Ultra so unfortunately I can't reseat my IHS for now. I'm pretty sure I had the right amount of coverage for the liquid ultra on both the die and IHS based on how it looked compared to the YouTube video.

delidding can really help increase the GHz headroom via lower temps...my chip always had the speed, but delidding and a strong custom w-c loop (have you considered that?) opened a whole new range...here are some quick temps for 5.0, 5.1, 5.2 and 5.3 GHz for the CPU Queen bench (related thread is here: http://www.overclock.net/t/1360912/thinking-of-overclocking-cross-platform-results-for-a-3770k-stock-turbo-3-9-ghz-to-5-3-ghz )
Warning: Spoiler! (Click to show)



Nice temps and overclock you have there thumb.gif I've considered going down the route of a custom water loop and if I was folding or regularly doing a lot of processor intensive stuff where an extra 200-300MHz would be beneficial then it would be worth the expense. I've been overclocking my PC really just to see how far I can push it rather than for any real practical purpose. Having said that I'll probably end up water cooling it at some point because I'll run out of things to play around with on air biggrin.gif I'm trying to shoot for a 4.5GHz 24/7 overclock keeping the temperatures in the low 70s. Ambient can be another 10C higher here at the peak of summer so it will leave me a buffer. Currently running a Prime 95 stability test at the moment and I've had to push VCore up to 1.275 already, although I'm getting a droop down to 1.26V according to CPU-Z.

-...4.5 should easily be possible at that voltage for your chip...with the right cooling, even with ambient temps in the mid-30ies, 4.8 is also not totally unrealistic..

...each chip will have it's own 'wall' it hits at a given speed...with some 3770K's it can set in around 4.4, others don't hit it until 5 or 5.1 and a few select chips don't see it far beyond that...but that wall is there, requiring a much steeper vCore increase for the next 100 MHz step.

...up until recently, I ran a 'closed-loop' Thermaltake Water 2 Extreme 240mm unit which I highly recommend for those folks interested in water-cooling but not yet looking at a custom loop. Other good closed loop ones would be the related KrakenX60 and the new Swiftech.

In my case, the closed loop was good enough for a nice, cool 4.9 daily (ambient usually is 22 C), with 5 a possibility though temps would slip into the high 80ies (pre-delid). Once delidded, I saw a combined 20.5 c drop from the delid and CL-U on the IHS- and going to a powerful CPU custom loop saved another 5-10 C (not done final testing yet as I should lap my IHS given its curvature)...with that overall temp drop, all my speed settings tr vCore had to be redone biggrin.gif ...because on average, I could lower vCore by 0.05v due to the massive combined temp savings...that's IvyBridge for you...VERY temp sensitive mad.gif

Intel(R) IPP JPEG encoder 7.0.1041 - Jul 19 2011;

- re stability testing, I would recommend Intel's actual stability and stress testing software Embedded in Intel's XTU (Extreme Tuning Utility)...more here: http://www.overclock.net/t/1313179/official-delidded-ivy-bridge-club/13050#post_19431442 .

I find it to be tougher, ie on memory test (which of course is also a CPU test in its own right), than Prime95 - XTU will heat up my system (post delid, custom loop) by 5 to 7 C MORE than Prime95...I'm running 32GB of TridentX and the CPU's IMC (memory controller) has its hands full with that during stress testing...and if you really want to / need to, you can set it to run up to 30 days... Intel's XTU is what the pro's are using in commercial builds and serious /pro-overclocking, per referenced post.

- ...look forward to follow your progress...by the sounds of it, you have more than reasonable speed targets in mind while also thinking about ambient temps during the hot season... smile.gif

Ladies and gents, a FULL guide and explanation of delidding a IB CPU, by me:

I think I need a new BIOS chip for my Extreme6 after searching for people with my same problems on google, that seems to be the fix.

1. My CPU multi is capped at 38
2. RAM is capped at 1600MHz
3. iGPU and anything related to it has been removed from BIOS.

Very crippling ailment to say the least. I don't want to send it to ASrock if I don't have to so I'm going to order a new BIOS chip to see if that's the fix.

You got dell'd
post #13386 of 33682
you mean the original delidded thread on Hard Forum.. Yeah that one went down like a lead balloon. But then I found this one on OCN. Not sure which was started first, may have to look at the original post and claim copyright and damages on val smile.gif I kid..
post #13387 of 33682
I started that one then realized you can't just upload pictures from your C drive... You have to go through the internet?? I had no idea how nor did I want to learn.. Thats when I decided OCN rocks.

I believe it is not all that bad. The problem seems to be that the thermal conductivity of most pastes cant keep up with the heat generated by the small die. That's why CLP/CLU does so well as it has 5-10 times the thermal conductivity of other pastes. People have used mx4 and as5 on die and still fall short of CLP.

Also the amount of rubber sealant they use creates a gap between the die and the IHS. This is the primary problem.
