I'm gonna have to delid my skylake so it doesn't feel so inadequate now! Thanks a lot Rich, it's all your fault.

I was hoping I wouldn't need to do it, but glad i did. Without delid, the 7700k's performance is poor from an OC perspective / expectation - delid unlocks the full potential. I have never delided a processor before, but it was dead simple - I just bought the tool and followed their video guide to delid and relid. I was hoping for a 20 degree drop, but happy with 30!

Prime is absolute crap, ive had an overclock for long time, using it for everything, benchmarking, gaming, and any other kind of stuff...tried prime and it failed instantly...

But i dont care about prime stability since ive never had a blue screen before using this prime crap..

So dont worry about prime stability..

If you aren't prime stable, you aren't stable. By definition.

I'm curious, did you use super glue when relidding like Rockit Cool shows in their video?

I bought the delid and relid kit, but I admit i'm a little hesitant to use super glue in case it needs to be redone in the future or if I dont get the CLU spread completely even the first try.

I did use super glue to relid (remember to let the glue set for a couple of hours, use in the corners). I used the same super glue and tape as recommended.

The tool is very precise, so if you're careful and diligent you shouldn't have any issues. It's so simple. The relidding tool also pushes down on the IHS to ensure a good contact.

Edit: I used a credit card to remove the black seal. Also remember to point the gold arrow on the processor in line with the arrow on the tool for correct orientation.

Hi,
Fantastic findings RichUK, could you run Geekbench 4 on your latest 5.1 delided achievement ?
The 5Ghz (is it ?) GB you posted at 5879 single core seems disapointing

Geekbench at 5.3Ghz: https://browser.geekbench.com/v4/cpu/1357306

Am I summing this up correctly? You had a "stock" stable overclock at 4.7, impressive enough in its own right, delidded at got a whooping 26 degrees average temp drop and are now honing in on a stable 5.0?
26 degrees yields about 300MHz?
Unless it throttles at stock-stock I dont see intel 'fumbling' with the TIM again..
(they should have named this one "The read Devils Canyon" and given it solder though.)

~60°C CoreTemp @ 5GHz but this CPU is also delidded, before delidding ~96-98°C with watercooling @ 5GHz

It's good to see the temps aren't an isolated case and this is becoming a trend.

What batch number is yours? It should be the long alpha / numeric at the bottom of the heat spreader? Be interesting to see if a different batch also has the same issue as mine, as this will then be more indicative of what to expect come official release.

Also, for my sake, can you run a 5ghz Geekbench with everything else absolutely stock and set memory timings to 15-17-17-35 2T and post screenshots? I can then do a direct comparison to understand if it is my memory?

Also, what board are you running? I need to run a fan over my VRMs as they get too hot when running at 5ghz and throttle back to 4.2ghz every couple of seconds, so I'll likely get an Asus Z270 TUF when they're released.

Cheers.

i got 2 7700K

L643G202 runs 5GHz with 1.312v
L643G213 runs 5GHz with 1.264v

Board is a ASRock Z170 OC Formula with Bios P7.30

i try Geekbench in a few minutes.

There also appears to be a new BIOS for my board (I noticed you weren't using v7 on your asrock), so might give that a try and hopefully get better memory speeds / timings.

Not bad... seems that the top scores that aren't fake or corrupted are using DDR4 at very high speed... possibly in the mid to high 4000s.

Yeah, memory speed seems to make a sizable difference in Geekbench.

I'll try the AVX blender run a bit later.

So in summary was Tom's results correct? You gain around 300Mhz over the i7-6700K with sane voltages applied? 6 - 7% increase or so?
