The short answer is yes. Keep in mind though that delidding voids your warranty. This is basically a little spiel to demonstrate the effectiveness of delidding a Kaby chip and relidding with liquid metal. I've done quite a few(dozens) of these now, its pretty much the first thing I do to a chip, before even trying it at stock usually. I admit to having been a doubting Thomas at some point, it was my opinion that all brand name TIM was pretty much equal. I stand by that opinion for IHS<->heatsink, but when delidding, the first time I used liquid metal was the end of using anything else under the IHS. It is just that good. I'd attempted to make a video of the entire delidding process. I was quite proud of myself, kept it logical and managed to not say ummm too many times. It took 40 minutes to convert a stock, very hot 7700K into a delidded beast, fitted and overclocked. Then I discovered my DSLR only takes 20 minute videos.. oops !! So a video will have to wait for the next chip I do. Nobody wants to see half a video.. Before and after delidding, I ran a few benches on the same gear to compare apples with apples. The bench consists of an Asus Z170i Pro Gaming, a single stick of Trident Z (8GB @ XMP 3733), a Silverstone 750W bronze PSU, a cheap SSD running Win 10 Pro, and a 120mm AIO (Corsair H60) with one fan at default speeds. I've also put a 120mm Fractal case fan over the board for the ram and VRM's, since there is no airflow on an open bench. I've used a little 2GB Asus fanless GT710 for the GPU, just to avoid using the IGP more than any other reason. If you are interested, the monitor is a 15" 12v/3w TV, which I've cut the wall wart off and wired the original connector to a molex. Its running off the PSU.... Everything else is wireless, so the only cord that needs to leave the case is the power cord for the PSU. The worlds chunkiest laptop This chip belongs to Juzz86. He just wants a 5GHz daily gamer, but the chip is way too hot for that, without delidding. All of the screenshots are 15 minutes of XTU stress test, with no AVX offset. Ambient is 19.3°c for all runs (heated room). I've used Thermal Grizzly Kryonaut between IHS and water block, and Thermal Grizzly Conductonaut for the delid, between the CPU die and IHS. Metal contacts under the IHS were protected using Liquid Electrical Tape. The IHS was reattached with a thin smear of ordinary bathroom silicon on each edge (after first removing the original adhesive). So for reference, on this particular board, with this cooler, etc.. I began by running the stock chip at 5GHz, looking for the lowest volts it would pass XTU for 15 minutes with. That turned out to be a disappointing 1.3v, and temps are way too high for that voltage. 50/45 @ 1.3v Max temps across all cores = 69-74°c I thought I would push it along a little, and see how high I could make it go without it exploding. I experimented with multiple voltages, this is the best I could do to get these speeds. I did get about 8 minutes into a 5.3GHz run until the test failed, at 1.5v and with temps in the 90's on all cores. At no point did the CPU throttle though. 51/45 @ 1.35v Max temps across all cores = 74-79°c 52/45 @ 1.42v Max temps across all cores = 79-88°c OK, so we have a reference set. Now, delidded. Still with all factors identical, apart from the delidding. I started with the 5GHz/1.3v run as before. Delidded - 50/45 @ 1.3v Max temps across all cores = 56-61°c (vs 69-74°c without delidding) Delidded - 51/45 @ 1.35v Max temps across all cores = 60-70°c (vs 74-79°c without delidding) Delidded - 52/45 @ 1.42v Max temps across all cores = 67-72°c (vs 79-88°c without delidding) So now to try for 53x, which although I could get running, would not pass 15 minutes of XTU and was hitting temps in the 90's across all cores without delidding... so I don't have a result for the stock chip at all. Note that I was pushing 1.5v into that effort too, XTU just crashed instantly the stress test started with any lower volts than that. Delidded - 53/45 @ 1.48v Max temps across all cores = 69-81°c I did try 54x, also @ 1.48v, but it crashed 11 minutes into the 15 minute stress test. Temps were ~75-85°. no throttling. I believe that if I were to stick the chip into my good rig, with a better mobo and moarad, I could have got the temps down another 5° and easily made 54x. I may even try later... The Z170i Pro Gaming isn't a bad board, but its a weakling compared to my Z270i Strix, and of course a custom 280mm loop with a Raystorm Pro is going to cool better than a H60. Remember, all of these benches are done with a pissy little 120mm H60 with fan and pump speeds running at default. Another thing to note here: With the stock chip, I spent some time getting the best volts/overclock. With the delidded chip, I simply duplicated everything. Justin will discover that he can get these clocks at lower volts as well, I just didn't try as I wanted to compare apples to apples. My personal opinion for some time is that efficiency on Kaby suffers once you get much past about 65°c. If you can keep temps under that, then major performance gains can be had. To prove the point.. I did start playing with the voltages @ 50x, as Justin wants a 5GHz daily, so those are the important numbers. Keep in mind that stock, the chip would not pass XTU at less than 1.3v. That's because temps across all cores ranged from 69-74°c IMHO. Get the temps to below 65° and the miracle begins to happen... Delidded 50/45 @ 1.28v Max temps across all cores = 54-61°c Delidded 50/45 @ 1.26v Max temps across all cores = 50-59°c Delidded 50/45 @ 1.24v Max temps across all cores = 51-58°c Delidded 50/45 @ 1.22v Max temps across all cores = 50-53°c I tried again at 1.20v but the test failed about 5 minutes in, so I bumped it back up to 1.21v. Delidded 50/45 @ 1.21v Max temps across all cores = 48-54°c Compare this with the original best I could do with the stock chip. 1.3v with temps of 69-74°c OF COURSE, RESULTS WILL VARY ACCORDING TO YOUR INDIVIDUAL CHIP, BUT A 15-20°C IMPROVEMENT IS A REASONABLE EXPECTATION FROM MOST CHIPS. I hope this post has been useful to someone I particularly hope Juzz86 is impressed Some video. In the absence of another 7700K to delid right now, I've gone a bit silly and delidded a Celeron G3930. Please forgive my calling the bloody thing a Pentium several times in the video. Also, for some reason I called TIM Thermal Insulation Material when of course I meant to say Thermal Interface Material. Insulation would be undesirable You may notice my delid tool is somewhat scarred, its done a bit of work. As it wears, the front of the silicon lifts higher.. watch carefully as the vice is closed. This never used to happen.. I usually just hold it down with my thumb on the bench vise, but I need both hands with the portable vise. Keeping it flat is necessary, it might be time for me to invest in another tool. I'm actually thinking that might be a reason for the underwhelming noise when it popped. This is simply the delid process. I'll do this in several parts, for easier uploading and downloading, and because I'm lazy The crap on my hands is what happens when liquid nitrogen contacts skin.. Since I thought the 'crack' was a bit underwhelming, I managed to snatch a chunk of the original failed video, and the noise the 7700K made when it let go... Applying the liquid metal. Relidding. OK, its a Celeron and won't overclock. I can however hit it with the big hammer which is Prime 95. I did so, and after one hour of small FFT's on Prime 95 @ Ambient 19.3°c, one core maxed out at 30° and the other maxed out at 31°. I wish I'd done a 'Before' test now... You can find a screenshot of this in post #43. .
