Just got in our first retail 7700K for overclocking testing and delidding this week when our Delid tool comes in from Overclockers UK.

I'm seeing a lot of scuttlebutt about people delidding this new CPU, guessing the TIM Intel used wasn't up to snuff? I've seen people "report" as much as a 10° difference once delidded.
 
Please kyle if you are gona test it with games do in a realworld scenario against older generation of CPUs, let's say GTX 1080 or even TX Pascal (because why not?;)) at 1920x1080 resolution in modern gaming....

It would be good for most readers here, specially those that are rocking a good old first gen quad/hexa i7s//Xeons and are in the fence on upgrades, an inter-generational gaming test with lot of chips, it doesn't have to be an IPC review, but instead what can offer every chip with the highest possible overclock, (this is specially useful for those Sandy Bridge users at 4.9ghz+ chips)

Think of it, it could produce A LOT of view and clicks for a very long time ;).. this is something that a lot of users here have been waiting and wanting for a lot of time..

i completly agree still havent found to much of a reason to upgrade half my computers from westmere xeon at 4.4+ or my sandys at around 5. honestly the newest hardware i rock is my 2670's. i even have a 5820k lying around that i havent had the reason to throw into anything.

From my reading the TIM used is just fine, the issue seems to come from there being to much space between the die and the IHS, when people remove it and reset it or direct cool, that problem is fixed.

I will be doing two delids here soon myself.

Oh man I wish I had that kinda play money. As is, I'm biting the bullet to replace the PSU on my main rig.
 
Wish Intel sell delided version of their CPU for those who wants it. Or make the lid part of the installation process where one would install like a heatsink. Of course, the mounting would be all builtin into the motherboard socket mounting mechanism. That way you can choose your own thermal paste and coolers can be designed for both situations.
 
mmm
I've come to wonder if the temp difference has to do with the gap between the DIE and the IHS

as in the glue Intel uses under the IHS

The real question is what to do after it's deliddied? Relid or run without...
Click to expand...

relid would be best for most

you would have to make a custom fit for coolers to make contact
few people did


thinking back I could've not glued it back on top but let it stay "loose" on top

the clamps hold extremely tight on the IHS once you put the cpu in

Looking forward to it

If you plan to delid once to remove the headspreader glue and keep the original TIM then delid another replacing the original TIM, would help to solve this mystery. I wish I thought of this when I did it.

Good, I already have some extra LU on hand and didn't want to have to order something else to test out. Does look to be cheaper however.

I have another vendor on the way in, as well as some Noctua NT-H1.
 
OK, been curing in the OCUK Delid Die Mate now for 24 hours approximately. The whole process was easy but it is a bit of a cumbersome tool to use. This tool I have is NOT spec'ed for Kaby Lake, so I had to take the Dremel to it to use it to RE-Lid the processor. Tool works fine stock for DE-Lid on Kaby Lake. The folks at OCUK did tell me a new one was on the way for them to sell. Block is Delrin so it is easy to work with the Dremel.

My Christmas color Kaby Lake. Now that I say that I should have painted the substrate black so it would be [H].

I took excellent 720P video of it with my pro cam. I shot 38 minutes of video during the entire process. This camera is OLD, but still excellent glass. I could not get a FireWire card to place nice with the camera last night. I spent three hours trying to get the video off the tape. I sold the camera on ebay two days ago and had to ship today, so my hands are tied now. New camera will be here Monday. If anyone in north Dallas can pull video off a mini-DV tape, give me a shout.
 
So i've seen some fancy shit having to do with gpus where people take off all the left over glue, tape up the top of the cpu to cover exposed transistors (more prevalent on gpus), but i assume the contact points on the kaby lake is the same idea.
The tape they've used us super 88 or 33+ or something. It's fancy electrical tape. It also helps prevent accidentally getting the conductive liquid metal tim on the parts you don't want it to be accidentally.
Then they apply the tim to the chip.
GPUs don't come with a heat spreader, but i've seen some people just lay it on top without securing it.

Then again i read somewhere that someone had an air pocket between the heat spreader and the cpu and it popped or something. Not quite sure.

Also that delidder costs like 50$. For a one time use item, that's fairly expensive. What does it actually do though?

It locks the CPU into the block when you bolt it together holding it in place by the CPU substrate. But it does not hold the IHS with clamping force, but it does limit z height, and gives the IHS room to slide in one direction. You then use a screw which pushes a block against IHS "sideways" until it breaks the adhesive. Mine made quite a POP! I was a bit worried.
 
Delidding the CPU is essentially just that. You are taking the heatsink ( lid ) off of the CPU. Once properly removed you must wipe off the old inferior Thermal Interface Material (TIM) installed by Intel and reapply new, more awesome TIM. Before new TIM is added, it is absolutely recommended that one polishes both of the interfacing surfaces to reduce porousness and maximize surface contact. This allows for better Thermal Conductivity between the hot surface of the CPU and the heatsink, giving you what is hopefully a lower operating temperature while slightly raising your thresholds for overclocking.

it bassicalyl a minivice with a form that fits a cpu. and i think they are only around 35$

50€ on sale, since they moved out the supply I guess
as kaby doesn't fit on the "gluing back together" side

was 80€ originally I think

while it is a vice per se
it's more like a mold that holds the cpu in place
and another moving part, the more vice like thing, slides the IHS off

then you can turn the lid around and glue the IHS back on
except it doesn't fit for kaby


the mini vice is an American product
and costs 35$ me thinks

Thanks guys. So they basically become mobile versions. Those new cores are tiny. So run without the lid? Or are there certain tolerances on the heatsink mounting that prevent that? I haven't mucked around with hardware on this level in years, I just build and go these days. :) Last custom thing I did was to modify the bios on my asus n61 laptop to accept an i7 cpu in place of the i5, and upgrade the heatsink to the 3 pipe version from the model that had the i7. Just some simple hex editing. :)
 
I feel it is a bit sad that Intel performance increases are so meager that enthusiasts start to de-lid out of desperation.
