UPDATE 09/03/13
I thought to update people on a few things:
1. Definitely nothing wrong with my CPU
2. 100% motherboard related in terms of the 2 DIMM slots no longer working
3. My MAX temps so far are 68c - despite me showing 82c previously. I have no idea what has changed, as my mount is exactly the same on my Antec 920. But if we take my 68c max temp now and compare it to my old 92c max temp, that gives me a difference of 24c in temperatures - which is insanely good.
4. I realised one of my cores is much cooler than the other 3 cores. For some reason Core 0 is around 8c cooler. I'm not complaining and I'm actually happy with it being COOLER than HOTTER

Here's a screenshot of my Core Temp after quite a few hours of folding a week ago:


5. I'm happy with my CPU de-lidding - Although I would have preferred not incurring any scratches on my PCB on the I7 - as long as it hasn't caused any harm, then there's no problem.
6. If anyone wants to re-seal the CPU, it can be done (as others have reported) via Black Silicone RTV glue. I wouldn't suggest re-sealing it personally as you are then re-increasing the gap between the IHS and die and more so causing yourself limited flexibility in the future

7. Here's a video GUIDE and explanation on how to de-lid your Ivy Bridge CPU's!
UPDATE 12/02/13
It is NOT CPU related, but Z77 board related!
Thus my CPU De-lidding went PERFECTLY fine (let's hope nothing more comes of it!)

Start of thread:

First of all for all information on de-lidding please refer to these threads:
[Official] Delidded Ivy Bridge Club -> useful for information and club joining
Short and Direct Delid Guide for Ivy Bridge -> useful for knowing where to cut

Secondly I would like to thank Swag and Valguar for not only their brilliant help and friendship, but also their help they have provided me and many other users for de-lidding.

Finally I would like to say that my de-lidding was NOT successful. At least not fully. I seem to have damaged the side of my PCB, where the IMC would appear to lead to.
I did many checks, as you'll see throughout the thread, but end of the day only RAM slots 3 and 4 work - meaning single channel RAM.

My goal and reason behind de-lidding was simple:
-Better temps
-Temps wanting to be lower due to me getting into folding

I first started my journey trying to de-lid an old Pentium 4 that I bought for only £1.90.
I actually wasn't successful - for one simple reason: The IHS and Die are SOLDERED on.

So here's pictures, pretty much chronologically, showing my progress on my I7:

First of all the blade is quite important - if you look at the blade I had during my Pentium 4 de-lid attempt, it was quite thick. I bought myself some nice blades on eBay - that are very thin indeed!




I also highly suggest getting Latex gloves and an anti-static wrist band!

Removing the CPU from the socket and looking at MX-2 application on the IHS (line method):




De-lidding the I7 for the first time








I suggest using a credit card to get rid of the black glue, both on the PCB and IHS - but then to clean it properly, to use something like the Arctic Clean with a cotton bud.

MX-2 on the die


So after all of that, I got a RAM error: At first: slot 2+3 wouldn't work. Slot 1 and 4 would work. Then I removed the CPU put paper, and slot 1, 3, 4 worked without any cooler on it. I put my Antec cooler on it and slot 3, and 4 only worked. Ever since then I haven't been able to get slots 1 and 2 to work:

So after my first attempt, I decided to get a little creative with the help of a few suggestions. I tried paper, paper + thermal paste, thermal paste (on PCB), double paper + thermal paste. These were all on that right hand side, in case it was getting heavy pressure from the IHS to PCB.














I was also told to check my ASUS Z77 motherboard pins. I did so, and took pictures - nothing wrong was found there.









Anyway, after all of this, I decided to just open it up one last time, and finally apply the famous CLU

CLU application





Again, extremely small damage on the PCB as you can see - but made all the difference with the RAM...I can only run slots 3 and 4. Pins on the board are perfectly fine. No paper is used in-between the IHS and PCB. Tried different combinations of RAM and also different mounts (no cooler full pressure vs no cooler with half pressue vs cooler vs cooler at half tightness)

Cleaning the IHS & PCB & Die:

I used Arctic Clean - absolutely excellent. I highly suggest it, as it is not only cheap, but also gets rid of CLU that even managed to find itself on my desk. Without the Arctic Clean, I wouldn't have been able to get rid of some CLU residue on my desk and PCB (by the die)!







CLU on and looking sexy!

CLU application is extremely easy, but you have to have A LOT OF PATIENCE. It took me a good 20 minutes to do both the under of the IHS and the die. What happened for me: I couldn't get the CLU to come out at a slow and controlled pace - more so when i tried dabbing the syringe on the die, it wouldn't "drop" - so I took my brush, dabbed it into the CLU syrings, and had CLU on the brush instead.
Barely anything was on the brush. I dabbed it once for the die, and dabbed it twice for the under of the IHS. It took a good while applying it on the IHS - but once it gets a "little warm" then it spreads with greater ease!













Final application of the CPU on the socket with MX-2 on the IHS itself (small dot method used)







IBT pictures:


More Temperature Pics
So here we go some more temperature pics - [email protected] for around 5hrs run-time de-lidded:







As you can see it depends what you are doing and how you are comparing.
De-lidding is fun and worth it to some extent, but be warned about damaging your CPU.

I hope this post will help someone is a few respects:
1. You CAN screw up your CPU with the SLIGHTEST scratch. My friend after seeing it, couldn't believe how small and HOW FAR it was from the die - caused the issue. We both asked ourselves (could it be the board that has shorted out on two slots? I'll have to try, but highly doubt that)
2. Temperatures were 20c better - you can judge how good or bad that is. Personally 20c is enough for the fans not to RAMP up to max 100% load. Meaning I can fold and go to bed in even MORE silence. CLU is a 10c improvement over MX-2, however I'm lead to believe over time MX-2 will = Stock paste. The stock paste IS NOT BAD, just the distance between IHS and die is what makes it bad. In fact if we got rid of the glue, and just had die on IHS with any paste, you would see an improvement. Maybe only by a few Celsius, but still something.
3. Using the dot or line method is recommended for the IHS - I also HIGHLY suggest using something like MX-2 over CLU ON THE IHS - if you ever want those markings to stay in tact.
4. Use CLU on the die and under the IHS - VERY SMALL AMOUNT - you shouldn't even go through more than 1/10th of what's given. If you have used any more - then that's way too much.
5. Take your time, have patience, realise the costs and benefit of de-lidding. I did it out of curiosity and got EXTREMELY unlucky, as the MOST important part of the PCB (right side is the IMC) got scratched. If it was the bottom (iGPU) or a little more on the outer edge, then it wouldn't have mattered.
6. Make sure you are wearing Latex gloves and/or an anti-static wrist band. It is quite safe to deal with the CPU, but better be safe than sorry.
7. De-lid on a SOFT surface - I used my mouse mat - but when placing down the CPU on somewhere, make sure it is a non-static place -> my desk made out of wood and/or on a latex glove.

I have found this experience very interesting and intriguing. Now I know the benefits and costs of de-lidding, first hand.

Sorry to hear the imc is damaged, but congratulations on your otherwise successful delid! Thankyou for posting this, going to make sure i get at least one more chip to practice on. I think i have one its a p4 2ghz SL5YR.
Which of these scratches, if they are scratches, do you think is the culprit?


+rep for sharing your experience in detail

Thanks for the rep bro!
The culprit is the top two ones. The corner one doesn't matter at all, as it is where the grounding of the chip occurs. By doesn't matter, I mean: doesn't lead to the imc. The right side of the die is imc related.
If I was literally 1mm to the right of those scratches I would have been fine...Just my typical bad luck

Glad you got to have the experience of delidding and see what it is all about and the great temp gains! It is a blast to do and the results are great. Sorry about the loss of functionality on the chip though. There is risk and not all of the chips make it. That's part of it and I know how it feels when it does not work perfectly.

My first 3770k got a scratch too when I delidded the first time, and it was not just a loss of functioanlty - it was dead. But I knew I was going to delid the replacement chip as soon as I got it anyway. So glad I did and I love the mod and the great temps. It really unleashed the Ivy for what it can do once that temp issues is fixed and well worth the risk in my opinion.

You will make your on choice, of course, but at least you got to do it once to see what it is all about!

bro those scratches may not be the problem. ı had mentioned that i had a similar problem like yours unlikely my pcb is scratch free.

I know buddy. But I checked the pins, and did the paper method suggested. What do you think might be the problem?
If I can't get hold of my friends i5, I'll be getting a cheap socket 1155 to test, for my motherboard...I would not be surprised if it is Asus related....lol

could you check the cpu pcb how bad it is bent ? you know you can't remove ihs without bending pcb. if it's so bent you have to make it flat like it used to. my all delidded chips were bent .i tried to make it flat by hand.but you cant put enough pressure to make it flat so it'll be a hard job. if you make it flat then we'll understand that it is %100 not bent pin problem

100% sure it isn't bent - as on the table it was lying flat. The pics of the CLU should show that.

I just realised something - I'm going to be ordering an i3 3225 for my mum's PC build.
I'll test to see if it works.
I don't need to disturb anyone's rig for that

Slow and steady did the job.
I was slowly wiggling it back and forth (almost in a rocking motion).
Just be extremely careful REMOVING your blade whilst it is inserted between the PCB and IS -> that's how I scratched mine!

Cheers for the rep too dude!
Do share your results here and in the de-lidding club, if you decide to do it

Some might be shocked as to what I'm going to type right now (copy and paste of what I wrote in the de-lidding club):

OK....I'm just going to say holy molly...

I'm on my Mum's PC build...I have to re-install windows (the pain), however....I have the following in her PC:
-De-lidded I7 with supposedly ripped IMC
-Stock Intel cooler with stock paste
-i7 with stock clocks and voltages
-16GB ram

Yes you read the last bit quite right - 16GB. All channels work - regardless of what speed they are running at right now (even though I think it is on XMP -> 1600MHZ) -> I'm currently typing this from her PC...
Which might mean three things:
1. I'm extremely lucky/unlucky
2. ASUS might get an RMA request for my Z77 for 2 fried RAM slots
3. My de-lidded i7 is 100% fine....

See it to believe it?
I know it is early days - but my PC would NOT boot with more than 8GB, and more so dual channel - yet on my mum's rig it has no problems (no errors no nothing)
If you cant see this - right click, open in new tab, and be shocked (if you have followed my case that is)



I will have to wait for my i3 to come in, before making any sort of decision, in order to be 100% sure.

I still don't think that Asus board fried 2 dimm slots. Your new chip will work okay i bet. Could you test your i7 on asus board with stock cooler ? sometimes mounting pressure may give such a result
