speed.fastest

Hi, how this after 43 minutes still no points & front pages?

Thanks Suzuki, Hideo

Strong result! Yesterday try 3 chip limited to 6775mhz, it looks like need venom to go above that.

Yes it is, but it seems all of that CPU is same limit at R15, 6775MHz, maybe limited by pot

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've had PSC that cant boot above 2400 8-12-8 1T or 2400 8-11-8 2T. Voltage around 1.85-1.93v. Put fan on the mem can help stability on high voltage. The kit is gskill eco 1600 7-8-7 1.35v green pcb.

Not always good, but seems all L639 scaling better on Cold than L643 (Its great on Air but not scaling good under cold).

Can i post Kaby result here? speed.fastest`s SuperPi - 32M score: 5min 54sec 125ms with a Core i7 7700K

WR of the Year so far, so perfect.

Strong! Does Venom make the difference?

Is the OS tweak? Very good job & CPU, well done

If you want to bin many kit better take 3200 c14 or 3600 c16/15. If not binning take 4133 or 4266.

Your CPU looking good, just had thermal limit, if your CPU is soldered i think it will fly under load. Unfortunately CPU core temp cant detect under 0 so we cant check delta temp between core & pot.

Awesome memory clock!

Great Score! Very nice

Whats your best b-die do at 3866 1.35v? This is G.SKILL 16GB 3600 16-16-16-36 1.35v XMP Mine 3866 17-17-17-37 1.35v (1.344v real) 3866 16-16-16-36 1.35v (1.344v real) error at 41.1% HCI Memtest

It works, but you need install Asmedia USB 3.0 driver to make it works. BTW the new BIOS (3201) exposed my Maximus VIII Gene capabilities, before this its not possible.

I agree with SI, start benching straight at full pot is better, even if only 1.6v vcore, less cracking possibilities. Almost all Skylake/Kaby Lake can run fullpot. Even if you do to many go up and down temp hotter than -135C you have possibilities to crack.

Yeah there are chip that hot and scale with cold, and cold chip that dont scale with cold, depend on CPU leakages. We definitely need much better TIM because it seems now high density die with same or more heat

Awesome Job! What this cpu did under ambient?

I agree with this, some batch is just not scaling under cold, but it seems you hitting thermal limit. Want solder indium?

Do you try max CPU Clock? If it good maybe your CPU is very hot, need higher thermal conductivity TIM to make it pass under load. Try change TIM again then heat up the pot to 70 Celcius, but dont start the system! (It may cause dead CPU). Then try again under cold. Heating the pot make it harder to crack the TIM under heavy CPU load in my experience. And dont forget start benching on -135 Celcius or Colder. I hope it fixed your problem.

Some CPU scale poorly under cold, but before that did you check CB R15 core temp load at 6-6.2GHz? Maybe hit positive and can you run fullpot? For me always start doing heavy benchmark on Skylake (i know its different) at -135 Celcius to reduces cracking TIM possibilities, cracking possibilities higher on -100 to -135 Celcius.

VTT is default at half of VDIMM, VTT only affecting memory stability (B Die might be need specific VTT for Ultimate Stability, every kit is different!), for more uncore you need more vcore or colder temp.
