slaske6 Posted January 21, 2017 Posted January 21, 2017 1.152V in bios. this value is the same whether using offset or Default settings (Auto). :thumb: nice one Quote
I.nfraR.ed Posted January 21, 2017 Posted January 21, 2017 (edited) My L643G I wrote about earlier, but after delid and AIO cooling, Grizzly on both, CB155.0/4.5 1.189V (measured with DMM) 5.2/5.0 1.328V VID is 1.104 according to OCF board. On LN2 and Z170 OCF - what I tested, it might be able to get higher with same settings 6.0 1.6V -100 6.2 1.6V -120 Then below -130 the "fun" begins. It starts freezing under load, nothing seems to help. Full pot same 6.0GHz profile I saved freezes when I start a bench. Pushing VCC PLL and CPU PLL to 1.8+ helps a bit, but still freezes on higher frequencies, 6.2 no go, while it is ok on higher temps. I will try to get MOCF to test. 6.0 cache booted, didn't test if CB will pass, I wanted to check cores first. Second try today - same thing. Can boot 6.5 1.73V no problem, can also set to 6800 same volts in Win. Can't run anything even at 6.0 when full pot - instant freeze on CB15 and CB11.5, have to restart from button on OCF. Before going full pot I tested again the saved profile at -90 6.0 1.6V and it passes no problem. Re-applied grizzly on DIE and IHS before the session, temps were staying under 0 this time. No cracks, no nothing, but same behavior under full pot. Definitely need to try another mobo before rejecting this chip. Also tried with XMP mem, low cache, 2T on mem, 1.8 CPU PLL, up to 2V VCC PLL, VCCIO up to 1.4, VCSSA up to 1.4. Tried different bioses, tried higher vCore. Mobo is running without radiaor on MOSFETs and sensors in bios show negative temps (both around -10) when going full pot. PS: Maybe I should stick to AMD, lol. Intel hates me.

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.

Did u removed all the black glue that holds the ihs and cpu together? If yes,try to level the ihs up a little bit with dielectric tape or something.Maybe u pressed out all the TIM above the core thats why you have no thermal capacity at all. chip seems really nice btw.

zeropluszero Posted January 23, 2017 Posted January 23, 2017 Picking one up shortly, is 639 looking like the best of the bunch so far? Quote
speed.fastest Posted January 24, 2017 Posted January 24, 2017 Picking one up shortly, is 639 looking like the best of the bunch so far? Not always good, but seems all L639 scaling better on Cold than L643 (Its great on Air but not scaling good under cold). Quote
zeropluszero Posted January 24, 2017 Posted January 24, 2017 ok, got me a 639 so now just waiting on a board. Quote

Noooo man, dont tell me it ...Because my 3rd 7700K is L643... My test for simply OC I did with Windows 10, temp in my room 22C. HW setup: Maximus IX Apex, AIO cooler Silverstone TD02 SLim CPU and BIOS setup: manual voltage, CPU clock 5 GHz, HT on, Cache 4500 MHz, RAM 3600MHz, LLC5, no delid yet ES 7700K 1.287V CinebenchR15 5000 MHz 1.325 V, max Cinebench 5100 MHz 1.45V retail 7700K L641G639 1.168V Cinebench R15 5000 MHz 1.265V Cinebench 5100 MHz at 1.345V AIO Edited January 24, 2017 by flanker Quote
FireKillerGR Posted January 25, 2017 Posted January 25, 2017 (edited) Getting an 639F today as well Edited January 25, 2017 by FireKillerGR Quote
RULE Posted January 25, 2017 Posted January 25, 2017 5x 639f all junk...batch mean nothing as usual Quote
Rauf Posted January 25, 2017 Posted January 25, 2017 5x 639f all junk...batch mean nothing as usual Yes it does, no cpus after 639 scale on cold... (so far of course) Quote
RULE Posted January 25, 2017 Posted January 25, 2017 Might be but my 643 scale... Inviato dal mio SM-A300FU utilizzando Tapatalk Quote

DennyCorsa86 Posted January 25, 2017 Posted January 25, 2017 It arrived today , when i will exit from hospital i will try it and if i was fortunately Quote
RULE Posted January 25, 2017 Posted January 25, 2017 To how high? The ones I have tried max out at or below 6.7, with proper scaling based on air results they should do 6.8. Same here. But looks like not a matter of scaling with temp, seems the chip is too hot for -196c Inviato dal mio SM-A300FU utilizzando Tapatalk Quote
FireKillerGR Posted January 25, 2017 Posted January 25, 2017 L639F -> 5G 1.32v cine and 4000 divider seems like a pain for the chip. Going to be sold :3 Quote
xMec Posted January 26, 2017 Posted January 26, 2017 L643 it's also a strong batch, but not all cpu from that batch are good ofc.. My first 7700k L643G218 seems it stops at 6700mhz @ -196 but need to retry and tweak some voltages, well it's not a top notch cpu but it's a good starting point for me ^^ Quote

On single stage not delid can do 5.8 4c/4t 3D bench, but i'm -40 full load. It scale good on cold... 1 Quote

Yes it should scale good too with ln2. Only bad has cbb at ~ -130 with mocf and -142 with impact. Then fullpot easy. Inviato dal mio HTC One M9 utilizzando Tapatalk Quote
