    Sounds like golden chip, the best i have seen on facebook is 5ghz 1.14v

    My CPU, L639F Batch, vid 1.168v (On Asus), not delidded, try to find max clock that i can validate to CPU-Z. Vcore 1.475v (LLC Lv6, stable at 1.475v). Cooler Custom Water 3x120 Ambient about 26-28 Cel

  • Cache seems typical to Skylake or even worse,among the cpu's i tested for 5000 cache lowest ones were with 1.30-1.31,4800 worked ok for 1.23-4 tough. Best cpu ever i touched would not crush when set 5

Anyone know how many individual chips are pulled from a wafer and how they go about batching and serializing chips? I believe I read, they used to designate a, b, and c for placement on wafer, from center to edge.

1.284 vid

1.255v 5G 45uncore Cinebench R15 pass without delid on H100

1.25 5G 45uncore Cinebench R15 fail, bsod on page fault

 

47x uncore passes at 1.26v

Your chip looking okay, but is your vid right? Because it maybe one of the highest vid on Kaby Lake i've ever seen until now.

I think vid just reads high on Gigabyte.

 

Asrock reads lowest of any vendor, followed by Asus. Have no idea where MSI fits in to the puzzle. . .

 

Just looked at my 7350k and it's vid is 1.08 on MOCF, check the rest of the cpu's and post in a bit.

thats what bios says at stock

friend here has a chip thats 1.32vid, similar volts for 5g

 

I think, you wrote voltage for turbo state. Try update BIOS, after load optimized settings and saved it and back to BIOS (check if your vcore voltage is set to "manual")

Sure Asrock reads lowest? For SKL Asus always was at least one step lower for me, and I had a 7600k that was above 1,2v vid on mocf - well, this one did not enter 5g at 1,4v os and might fail specs :D

 

With Skylake I am not 100% sure but on Kaby I am almost certain the lowest reading vid's will be on the MOCF. I still think it's best to just test with R15 lowest volts 5-5.3Ghz pre delid on any board.

 

Here's what a 1.08v vid 7350k does on antique relic MOCF :D

 

R15 5.2 / 4.5

R15 5 / 4.5

passed 1.195v but froze opening cpuz go figure lol

 

best 5 / 4.5 R15

Looks good, I only did raw check on my i3, vid is same but needs more for 5g, I slacked :D - interesting that es shows 4,1 ghz max

 

Same vid on MOCF?

 

This cpu can run 5.3 / 4.5 threaded as long as memory is 4000 or lower, 4133 divider seems to max it out at 5.2 maybe a bit more noticed this as well. Also this IMC is crazy on this chip, in fact it's the best imc in house lol All air cooled as well so on cold should fly!

hmm good question not sure off the top of my head but for the above 1.35v

Vid 1.152 ,test on z170 M8e at 16 degrees ambient with corsair h100i,full avx,cache 4500,ram 3200,Llc 5 .

 

5 ghz@1.23v , 5.1 ghz@1.28v & 5.2 ghz @1.34v

Incredible. That chip needed 1.25v llc6 for 5g r15 on hero alpha. Non avx (26.6) 5.1 was 1.344v llc6. Not quite sure how it's so low on m8e....n1.

Didn't test lowest on prime :D.
