ObscureParadox Posted December 12, 2014 Posted December 12, 2014 Hmm, these Vietnam ones are looking a little bit better at least. Not god awful anyway. Quote
Achill3uS Posted December 12, 2014 Posted December 12, 2014 (edited) got new cpu today, strange vid 1.263v ?? after battery out full cmos it starts at 1.363v more strange, maybe bios bug 4790k L423B494  but it seems nice air chip 5G 32M at 1.28vcore / 1.85vccin tried low vccin like 1.65-1.75 but ive got bsod, so it seems to like 1.8v+ ln2 test soon, fingercross   on XP i can go lower vcore...

The latest Bios is supposed to fix it, so upgrade & it should be fine. Quote

Achill3uS Posted December 13, 2014 Posted December 13, 2014 (edited) hasfail again  4790k L423B494  crap cpu on ln2, -93 CBB / -106 CB max clock 6.3GHz at even 1.90vcore/2.40vccin   another sandbag, enough for today  4670k L402B455 5GHz air 1.45v 32M 6.2G valid 1.80v LN2 -123cbb Edited December 13, 2014 by Achill3uS Quote
subaruwrc Posted December 13, 2014 Posted December 13, 2014 4790k X438B021SuperPi32m max 6,2 @ 1,55-1,65v LN2 Cinebench R15 5,9 @ 1,45v LN2 6,3 no way  even with more vcore like 1.7-1.8v ? why so low voltage ? Quote
sergmann Posted December 14, 2014 Posted December 14, 2014 For that more Volt? CPU is not bad, CB -130 but dont scale with more Volt. Quote
Farjam Posted December 14, 2014 Posted December 14, 2014 For that more Volt?CPU is not bad, CB -130 but dont scale with more Volt.  like this chip : http://www.8pic.ir/images/idb8yopxqy1f0zak4f1l.jpg  Vccin 2.09v it hates higher Vcore and Vccin LoL L421B995 Quote
rtsurfer Posted December 15, 2014 Posted December 15, 2014 like this chip :http://www.8pic.ir/images/idb8yopxqy1f0zak4f1l.jpg  Vccin 2.09v it hates higher Vcore and Vccin LoL L421B995  Is that Vcore for real.?? Quote
rtsurfer Posted December 15, 2014 Posted December 15, 2014 Damn. And I thought this guy had a good CPU  http://hwbot.org/submission/2694680_frenlynhn_cinebench_r15_core_i7_4790k_1223_cb  Although I Sincerely doubt he is on Air, but whatever. Quote
Achill3uS Posted December 19, 2014 Posted December 19, 2014 did someone try to delid one of these low volt air and ln2 sucker chips and test it over again? Farjam maybe? its quite funny that my L423B 4790k is about 100C hot under linx at only 1.17v 4.6G on advanced aircooling, airconditioned room too bad i cannot afford to kill a 400 euro chip, but would be interesting to test it recently... maybe its just the bad thermal conduction causing the subzero problems with these new chips, otherwise i really dont understand why so many haswells fail and did not scale well with cold like others do with no reason according to aircooling pretests... its kinda annoying...

t8y Posted December 27, 2014 Posted December 27, 2014 (edited) 3420B747 Costa Rica VID 1.039  4.8ghz 2c2t spi 1m winXP (OS was setup for 1m, cbf changing maxmem) 1.35v / VCCIN 1.94 5G impossibru ambient  probably wont bother testing it with LN2 need a good ambient one of these really and already have one that does about the same/better, but with a stronger IMC Edited December 27, 2014 by t8y Quote
subaruwrc Posted December 28, 2014 Posted December 28, 2014 I removed the ihs from 2 cpu-s with different benefits. 1st was a L417B973 malay chip which did 6.1 max valid on stock configuration under ln2. Didn't bother to check air results with that one. Then I removed the ihs and changed the paste underneath with gelid gc extreme. Benefit is 200mhz, 6.3 valid and 6.1 superpi 32 but thats the max. Another chip is a 3419 costa rica which got delided and the ihs polished in addition because it was concave but the benefit is a short 100mhz in max validation. previous 6.1 is now 6.2 with 1.825v 2.4v vcin,no voltage scaling above this. I got a little mad and tried the chip with on die ln2 cooling but the results were far worse as the chip did only 5.9ghz max validation with the ihs removed. Chip is alive but useless. I hoped to gain at least 300mhz cause it was a hot chip and got bad ihs but no luck. Anyway it did 1.54v superpi 32m at 5ghz on air. 5170mhz 1 core valid with 1.55v and 5.2ghz with 2 cores with 1.54v after changing TIM. Quote
subaruwrc Posted December 29, 2014 Posted December 29, 2014 (edited) I bought 2 other G3258 chips today. Both banana.. L421B829 #0644 VID 1.116v 4.1ghz 1.2v cinebench 15 ok - 4.2ghz fail L421B829 #1630 VID 1.092v 4.2ghz 1.2v cinebench 15 ok - 4.3ghz fail 4.5ghz cb15 needs 1.4v Edited January 5, 2015 by subaruwrc Quote
ObscureParadox Posted December 30, 2014 Posted December 30, 2014 (edited) Just got one in today with a batch number which isn't on here yet. 4790K L414C937 will be testing soon. Â VID : 1.072v Edited December 30, 2014 by ObscureParadox Quote
Achill3uS Posted December 30, 2014 Posted December 30, 2014 another garbage 4790K batch: L423B697 4.5ghz 1.20v linx stable 5ghz even 1.35v no boot very hot chip 1.20v 100C load Quote
subaruwrc Posted December 31, 2014 Posted December 31, 2014 another garbage 4790Kbatch: L423B697 4.5ghz 1.20v linx stable 5ghz even 1.35v no boot very hot chip 1.20v 100C load  if its very hot at even 1.2v im not surprised it is not willing to boot at 1.35v try better cooling or delid it Quote

Administrators websmile Posted January 10, 2015 Administrators Posted January 10, 2015 @subaruwc - did you test on win7 or 8? The chip does much worse than mine on air, I am really surprised it runs that high on LN2 Quote
subaruwrc Posted January 10, 2015 Posted January 10, 2015 @subaruwc - did you test on win7 or 8? The chip does much worse than mine on air, I am really surprised it runs that high on LN2 Â I did the air pretest on w7 because i didnt know it has such a great impact on max cpu-z. this chip should be 5.2 with 1.4-1.45 on xp.
