ChanceCoats123 Posted June 5, 2013 Posted June 5, 2013 I think all of this stuff we've been seeing about 2V+ is due to bad CPU-Z. Use 1.64.2 from the CPUID Haswell Reviewer kit: http://www.cpuid.com/news/76-reviewer_kit_for_intel_haswell.html It says it contains 1.64.1 but the file actually has 1.64.2 in it. Hokiealumnus at OCF also confirmed that the ES chips could set voltages over 2v. The retails got locked farther down, but the screen shot from a month or so ago was actually reading correctly at 2.5v. Quote
l0ud_sil3nc3 Posted June 5, 2013 Posted June 5, 2013 Replacement chip is not so good, it needs about 1.34v for 5Ghz 32M. Quote
flanker Posted June 5, 2013 Posted June 5, 2013 its with your LN2 pot test (under zero temps?) or you set back some aircooler? Quote
l0ud_sil3nc3 Posted June 5, 2013 Posted June 5, 2013 its with your LN2 pot test (under zero temps?) or you set back some aircooler? -112c Quote
Crew Vivi Posted June 5, 2013 Crew Posted June 5, 2013 -112c why only -112, these cpu's have bugs? Quote
Crew Vivi Posted June 5, 2013 Crew Posted June 5, 2013 yes, but ussually around -130C yoh! im actually excited to run coldbugs again . no more ultra frost. then again with mem on ln2 will probly make frost anyway. But its gonna be fun to fight some CB again! now good pots and great pots can battle it out Quote
I.nfraR.ed Posted June 5, 2013 Posted June 5, 2013 All these have CB? And what about CBB? That would explain the lower frequencies, even if they scale with excessive volts. Quote
Crew Vivi Posted June 5, 2013 Crew Posted June 5, 2013 All these have CB? And what about CBB?That would explain the lower frequencies, even if they scale with excessive volts. yea it doesn't help that these cpu's are already warmer than ivy, now they have CB too. gonna be hard to get them to high clock. at -100 that cpu is probly -80 inside :< Quote
I.nfraR.ed Posted June 5, 2013 Posted June 5, 2013 (edited) Cores would be on the positive side of the temperature scale when loaded properly. No wonder they die with 2.2V @ -120C. Plus VRMs inside are not making it colder. Edited June 5, 2013 by I.nfraR.ed Quote
K404 Posted June 5, 2013 Posted June 5, 2013 Yea, best CB I saw at the OCN launch event was -140 pot base IIRC. SHOULD have been with GC-Extreme, but I dont know. Are we binning for 5GHz? Some of the chips we had were running wPrime at 4.9GHz, 1.25v, but 5GHz needed a BIG jump in voltage. I honestly think these chips are cooler than Ivy, from what i've tested so far. Quote
flanker Posted June 5, 2013 Posted June 5, 2013 I think, some problems will be fixed next year with Haswell refresh. Quote
xxbassplayerxx Posted June 5, 2013 Posted June 5, 2013 Thanks for the link, but I can for sure tell you I set 2.9v for input voltage and 2.2v for vcore and cpuz reads vcore exactly as that. All voltages were adjusted in the OS with TurboV. The M6E has never read vcore differently than what is set in the bios, at least in the all the bios's I have tested. I meant that I think some of the earlier scores we saw posted where it looks like 2V+ was used might have actually been using less voltage, it just looked that way because they used older CPU-Z. yea it doesn't help that these cpu's are already warmer than ivy, now they have CB too. gonna be hard to get them to high clock. at -100 that cpu is probly -80 inside :< We need someone to be brave and test a delid with extreme cooling.

rsnubje Posted June 5, 2013 Posted June 5, 2013 Well, I've got another batch you don't want... L312B364 - 4.9GHz Cinebench 11.5 stable... SS cooled. Quote
Calathea Posted June 5, 2013 Posted June 5, 2013 We're seeing some pretty extreme differences on these chips. Just today I saw a friend post on facebook 4770k Cinebench 11.5 @ 4,9 GHz aircooled. C0 ES though, no retail. I can't remember Ivy being this weird? Quote
rsnubje Posted June 5, 2013 Posted June 5, 2013 (edited) Most ES samples, especially the press ones, clock pretty decent. @flanker, tried from 1.45 till 1.6v, but didn't matter. This is an ES I tested earlier. Too bad it has bad VR. Edited June 5, 2013 by rsnubje Quote
Alex@ro Posted June 5, 2013 Posted June 5, 2013 (edited) l306b335 5 ghz not doable on air,dice -70 ran 5700 for 1m,5600 for 32 with 1.7,before pumping 2v ran into condensation issues on mems so the fucker escaped,will harakiri him asap Edited June 5, 2013 by Alex@ro Quote
nachtfalke Posted June 6, 2013 Posted June 6, 2013 4670k- L310B514-Malay boot 5 ghz/1.44-air http://valid.canardpc.com/show_oc.php?id=2824658 Quote
flanker Posted June 6, 2013 Posted June 6, 2013 4670K retail - L310B515 (wow only one number different) AIR (22 ambients, cooler Gelid Tranquillo): Superpi 32M 4732MHz 1.4V all cores , 1M 4770 , OCCT stable 4583 MHz 1.352V Quote
K404 Posted June 6, 2013 Posted June 6, 2013 L310B479 4750MHz/ 4GHz Uncore, 4C/4T, SPi32M @ 1.375v. Less = crash. Didn't feel like pumping in more Quote
nachtfalke Posted June 8, 2013 Posted June 8, 2013 4670k retail -L310B520/air spi32m-4755/all core-1.280v Quote
K404 Posted June 8, 2013 Posted June 8, 2013 Hey coolhand Please can you test higher MHz? 4.5GHz is still within the "very easy" zone Quote
coolhand411 Posted June 8, 2013 Posted June 8, 2013 (edited) sorry ..just got this darn thing ,will push once I get proper OS (can't install XP for some reason ),I think 4.6 @1.2v and 1:1 is not bad (h20) Edited June 8, 2013 by coolhand411 Quote
