I just redid my last week after 6 months and it was still as wet as the day I put it on.

Just started a friend's computer that's running a 4770k I delidded, currently running 29c at idle (havent installed all the stressing stuff yet) and a VID of 0.72v, are we looking at a winner?

Hi there,

anyone tried the hair dryer method with success? Or ist vice and hammer still the better way to go?

And can sombody tell me, if the CLU should be applied to both the die and the inside of the ihs or is only on the die enough?

Thank you!

Some people have delidded with hair dryer combined with hammer and vice. You can get better contact by putting CLU on die and inside of the IHS.

Don't check VID, check Vcore. Cpu-z 1.64.0 (newer is broken on many boards) and hwinfo64 are good but make sure to check vcore not vid, especially for load voltage

29c is hotter than me idle, but two things: Firstly, it's >heavily< dependant on room temperatures etc.. secondly, you're at ~0.72v idle which means you're idling, but not using c6/c7 state. You probably have integrated graphics on too - Manually enabling those idle states as well as disabling iGPU if you're not using it will cut some watts and degrees.

Both of those things you said are basically not indicative at all of CPU quality - everyone has them. If you want to check CPU quality and do basic stability testing, i would highly reccomend:

Use all voltages Manual/Override, not adaptive or offset.

Manual 33x for Uncore/ring/cache, not default. Use 1.15v for it - you can overclock it after you have your max stable core overclock and everything works fine. If you leave this at default, on many motherboards it turbo's and uses for example ~40x with 1.25v if you have overclocked your core multiplier. This adds variables and can be confusing or worse, cause instability if something weird happens with it, and you don't want to deal with that until you're at 45 or 47x whatever core and you want to overclock uncore after. 47x/40x is better than 46x/46x in most applications, too - it's really a secondary concern, unless you have some niche where it is important - even so, you'd probably still want to overclock this way.

Set 1.8vrin
set VRIN llc max to stabilize that ~1.8
set 1.23vcore (IVR increases this to ~1.25v under load)
set core multiplier to etc.. 42, 44, download this - http://download1346.mediafire.com/pf1y1esf6qhg/2laifu8xqi6vz2g/x264+Stability+Test.7z

^With those voltages, you can change only the core multiplier. Your CPU might be stable at anything from ~41x-~48x core, most likely 43 or 44. This is a solid profile where basically nothing can go wrong and you can narrow down on what works with a little testing, and then work from there. If it doesn't work, don't change any voltages - just lower the core multi til it does, then work up after everything is verified stable and working, nice and slowly thumb.gif

I mostly do/recommend this because there's some weird stuff with Haswell. Throwing way too much vcore can make you unstable, for example. Changing multiple variables with Uncore, Core and IMC can all make you unstable, they all throw the same BSOD codes and it's quite confusing - as it is now, the best OC practice is to narrow things down so that the only ways you can be unstable are vcore and vrin, then play with them so that you can guess constructively what is causing you to bluescreen, as opposed to randomly changing stuff and hoping for the best~

If any issues/questions, the haswell overclocking thread with statistics here on OCN has lots of info and people to help with troubleshooting. This turned far more ranty than i intended wheee.gif

As a final note, the goal of x264 isn't to crash you as hard/fast as possible. It also won't give you anywhere near absolute worst case synthetic tests in terms of temperatures - it should be good enough for you to make an OC that never shows any signs of instability for whatever criteria of work/gameplay that you want, however

Please add me to the club. I wasn't really looking for more OC headroom... I just wanted to quiet things down. Running at stock, my desktop gets rather noisy when I encode video (hits the CPU really hard). For practice, I first performed a delid on my HTPC Celeron CPU, since I would like it to run cooler too in order to keep fan noise down. Since it went smoothly, I went ahead and knocked the lid off my i7-4770k. Details for both below.
Haswell Celeron G1820 Delid (Click to show)

I think I may be the first person in the world to delid this chip. OCN exclusive LOL.

Here it is after smacking it with a hammer:


One peculiar point of interest with the Haswell Celeron, there are actually some delicate points under the IHS adhesive that aren't there on the i5 and i7 Haswells. I think the vice-and-hammer method is the only safe way to delid one of these chips. I don't know if the Pentium or i3 chips have this too:






Anyway, after applying CLU to the underside and using RTV silicon to put it all back together, everything is working fine. I didn't take a screenshot of Realtemp before the delid, so you'll just have to take my word for it that the hottest core would hit 53°C running Prime95 with large FFT. Here it is after while running Prime95 large FFT (stock cooler):



It didn't even break 40°C! HA!!

There's hundreds of pictures of 4770k delids so I'll just throw mine up without narration:

Prime95 After:
