5 years since I posted in this thread.

The 4790k, that I posted in this thread, is still running at the same clocks and volts (4.8GHz|1.28 volts), with the original application of CLU.

Anyway, today, after so many years I tried it again out of boredom. I must have seen 9000 videos of people delidding with razors, and even a vid with someone delidding with the plastic package from his CPU, and another guy using a small plastic card. The idea was that you only need a tiny 2mm cut in one edge, and then use the card and do the rest. Sounds totally trivial, right?

Anyway, to make a long story short: I really tried today with a small exacto knife just to cut a small 2mm slit in the side. NO DICE. I tried several times and took my time, doing exactly what I must have seen a million times in videos. The black silicone is just so rock hard I wasn't able to even get into it, whatsoever. So I aborted that attempt too. I figure there is no other way than using a tool, fortunately you can now get these mini vice delid tools from China for €5 where people had success with. If I am bored again I might just get one of those, but not sure whether I care with such an old CPU. I was sooo convinced I get it right today...grrrrr....
It's much easier to knock it off with a vise. I've pushed 3 off without issue.

Or for peace of mind get one of those chinese knock off delid kits, or if you really want to then go the Rockit delid or Der8auer tools but the chinese knock offs work just as good for half the price.

I'm quite surprised that CLU stays good for so long yeah. My 7700k is on my original delid and CLU 2 years exactly now and still the exact same temps as when I first delidded and OCed to 5Ghz.

I'm thinking of cleaning my H115i rad a bit and going for a bit more of a "dangerous" overclock as I have some room left in the voltage before it really gets up there. Running 1.36v now but I know it will survive up to 1.45-1.46v for a while, even if it will probably degrade at that voltage, but yeah 7700k's are pretty cheap nowadays so.. let's see if I can make 5.2Ghz or something on all 8 threads.

It will pretty easily do even 5.3Ghz without HT enabled so I have high hopes 5.2Ghz will run on HT enabled . If my H115i can keep the temps low enough (<90c with AVX stressing) before saturating and getting too hot.

EDIT: Ok, holy mother of.. It needs a LOT of volts to even remotely run 5.2Ghz stable with HT enabled... So far it seems 1.488-1.496v will kind of do for Prime AVX and temps aren't even that bad yet (94c hottest core) but that is a bit too much voltage even for my suicidal liking. I mean, i ran a 2500K on 5.3Ghz 1.525v for over 2 years and that thing is still alive somehow so..

EDIT2: It hates multipliers over 50.. I'm using BCLK OC now for 50x102.5 for 5125Mhz core and 4715Mhz ring and 2733Mhz RAM and this works just fine on 1.448v load. Temps maxed at 86/88/80/76 in Prime 27.9 AVX Small. Probably going to run high 60's low 70's in games. Totally acceptable temperatures imo. It should live for at least another year or so at that voltage / temperature before degrading too much.

Hey guys I wondering, someone has lapping the die on 9th gen to remove the solder?
How much height reduce it? Do you use the stock IHS or 3th?

Rockitcool makes a 9th gen IHS. It’s only about $15

Removing the solder isn't the same as lapping the die.
Removing the solder doesn't exactly reduce the IHS height. To reduce the height you have to remove the Intel silicone adhesive and then relid (which is only a mm or so).
So you have to remove the original black adhesive (and preferably sand the edges of the IHS also)

Had the itch to de-lid something since I didn't have anymore Intel chips to de-lid I took a razor to my Athlon 64 x2 3800+ that kept running at 112c no matter what heatsink I used. 70c drop after de-lidding and using Noctua paste between the die and IHS.

Yea but you’re not ‘supposed’ to use a non conductive paste between die and ihs.

Right. That’s true, and I misunderstood his point. My point was that instead of lapping, you’re better off just buying a new IHS when someone else has already done it and is charging a nominal fee.

Frankly I think you lose a lot of the performance gains by relidding in the first place but that’s just my opinion.
