zeropluszero Posted October 14, 2014 Share Posted October 14, 2014 how high are you guys going on vccin on ambient cooling? Quote Link to comment Share on other sites More sharing options...
Guest Sinebrychof Posted October 14, 2014 Share Posted October 14, 2014 http://i.imgur.com/MaT5lol.jpg  On water, 1.458 vcore set in bios, 2.16v vccin. I find higher vccin much more stable than low. Quote Link to comment Share on other sites More sharing options...
TASOS Posted October 14, 2014 Share Posted October 14, 2014 how high are you guys going on vccin on ambient cooling? Â I believe 2.1volt is enough for short tests and quick benchmarking. Quote Link to comment Share on other sites More sharing options...
Guest TheMadDutchDude Posted October 14, 2014 Share Posted October 14, 2014 I didn't need above 1.95v for 5.3GHz but my chip wanted at least 2.2v for 5.4GHz. Â Experiment, try it out and see how you get on. Quote Link to comment Share on other sites More sharing options...
zeropluszero Posted October 14, 2014 Share Posted October 14, 2014 Fair enough. I'll give it a bit more vccin. I really want to see this chip do 5g haha Quote Link to comment Share on other sites More sharing options...
Guest Sinebrychof Posted October 15, 2014 Share Posted October 15, 2014 I use 2.16v vccin 24/7. I find lower vccin, 1.85-2.05 a lot more unstable. Quote Link to comment Share on other sites More sharing options...
stasio Posted October 16, 2014 Share Posted October 16, 2014 ^1.60-1.70V vccin ? Quote Link to comment Share on other sites More sharing options...
MaJ0r Posted October 16, 2014 Share Posted October 16, 2014 I use 2.16v vccin 24/7. I find lower vccin, 1.85-2.05 a lot more unstable. Â Fcuk, my best Hasfail could do 7GHz validation on LN2 with Vccin = 2.2V Is it such a big difference between Hasfails and DCs or you guys are crazy with such big amount of volts? )) Quote Link to comment Share on other sites More sharing options...
slaske6 Posted October 16, 2014 Share Posted October 16, 2014 i only use 2.3-2.4 vcin for 6500 mhz 2d and 6400 3d . and never tryed higher Quote Link to comment Share on other sites More sharing options...
superV Posted October 16, 2014 Share Posted October 16, 2014 It's the same chip, sorry about that. The VID is 1.036v and my phase is at -45c (ish) on idle. The CPU doesn't run hot and raises the phase by about 5 - 6c during long loads.  I've constructed my den in the garage and I will be benching tomorrow to try to see if it will go any further. I reckon it will hit 5.5GHz on <1.6 volts but I need to try to get it to boot into 7. I will probably end up re-installing to see if that's the issue or not.  did u try direct die cooling with the phase? just wondering since my cpu is delidded. what gain can be with direct die cooling?

Guest TheMadDutchDude Posted October 16, 2014 Share Posted October 16, 2014 Subzero and direct die cooling just murders these chips. From what I've read and heard, delidded chips cannot be frozen. They just die. I'm guessing it's because the FVIR gets slightly damp and shorts, causing instant death. Even resealed chips just don't survive.

Guest TheMadDutchDude Posted October 16, 2014 Share Posted October 16, 2014 I think you'd have to insulate it very well. The risk is all yours if you freeze it though. Quote Link to comment Share on other sites More sharing options...

Alex@ro Posted October 17, 2014 Share Posted October 17, 2014 i freeezed both a 3570K with liquid metal underneath the ihs(big mistake if i think now) and both a 4770K with gelid gc-extreme under the ihs.Both times no problems at all,the 4770K did better than stock paste! It was under dice though -64 temp of pot... Quote Link to comment Share on other sites More sharing options...

Farjam Posted October 17, 2014 Share Posted October 17, 2014 (edited) Another weird chip that loves low vccin... 4790K L421B995 i use hwinfo to monitore all of voltages  5ghz vcore=1.19v vccin=1.62v(set in bios) http://www.8pic.ir/images/s9e13dvu8c1hvjl2mqfj.jpg  5.1ghz vcore=1.275v vccin=1.65v(set in bios) http://www.8pic.ir/images/hljr2j2yv6aczitcxcu3.jpg  5.2ghz vcore=1.339v vccin= 1.72v(set in bios) http://www.8pic.ir/images/krd8oykza5kkizc6eyb9.jpg  again higher vccin , i mean 1.8+ makes max clock for sp32 only 5ghz and no boot higher than that... i have to play with vccin between 1.6v- 1.75v i think it's a bad sign to not scale with vccin higher than 1.8+ ... all of those chips like it that i have benched so far had bad CB... between -76 to -105 Edited October 17, 2014 by Farjam Quote Link to comment Share on other sites More sharing options...
Alex@ro Posted October 17, 2014 Share Posted October 17, 2014 Hope to find a connection,4690K@L422B791,can do 5 ghz 1.23 windows xp 32M,either 1.65 or 1.9V or 2.1V,same clock,no improvement. 1 Quote Link to comment Share on other sites More sharing options...
Farjam Posted October 17, 2014 Share Posted October 17, 2014 my 4690k@L422B787 was a little like yours, but it needs 1.34v for 5ghz vcore if i remember correctly, and no difference between 1.65 vccin to 1.9v (but sometimes higher than 1.8v gives me bsodes during win startup if i use asrock z87 oc formula) and the cb.... it was -76 !!!!!! http://hwbot.org/submission/2647417 Quote Link to comment Share on other sites More sharing options...

fat4l Posted October 19, 2014 Share Posted October 19, 2014 (edited) So guys, i've finally tweaked my cpu... Â 4800mhz_1.30V/cpu + 4600mhz_1.31v/cache (1.95V vccin under load) Â Super stable, aida64 stability test 7hours. occt:cpu_large data set = 1hour stable occt:linpack = 1hour stable Cinebench loop,xtu bench, aida64 benches, pc and 3d marks..etc.. All this with 70-85C max(delided cpu). No crashes/freezes whatsoever... Â Now, the problem is 4900Mhz. Cant get it stable even with 1.4V. Thats 0.1V increase but only 100mhz gain.. Tried vccin 2.02 under load and didnt help.... Can run aida64 stability test for hours, can do XTU for hours too, can do cinebench loops, wprime 1024M etc... But in occt:cpu it crashes to bsod in 5 mins. Â Any ideas ? What might help, or should i "idgaf" about occt lol ? Is aida64 nuff? Â Â Batch L425... Â Â Â Also, how did u find out that ur cpu need "lower" vccin ? like..1.7v lol Edited October 19, 2014 by fat4l Quote Link to comment Share on other sites More sharing options...

Guest Sinebrychof Posted October 19, 2014 Share Posted October 19, 2014 My 4790k is delidded and worked fine under ln2. My first horrible mistake was that I used liquid pro and it freezes at so cold temps, I had very weird low cold bug first with it, -147 and I knew it couldnt be right. I switched to gc extreme and now cold bug was -137 but cpu isnt a killer. I'm sure delidding doesn't aid clocks on ln2 at all, atleast when looking back when people first tried that on ivy on this forum. So many ruined chips. I covered the pcb around die with vaseline though. Â What I got then was 5.8 cinebench 1.62 vcore and 2.5-2.65 input? and 6.1 32m. Not really happy.

Achill3uS Posted October 21, 2014 Share Posted October 21, 2014 (edited) its quite frustrating that batch doesnt even matter anymore, about these pentiums... i did not bench long time ago, when i fist saw the results about these bastards, i felt like WANT ONE but now... need to find a good one it seems not an easy job, its completely about luck, what VID you will get.  Tried 2 boards, ASUS and GBT Z97 too... same results...  3418C011 VID 1.056v 4.8G 32M 1.40v pass 4.9G 32M no matter what vcore/vccin no go  3418B986 should be a good batch for everyone VID 1.056v 4.8G 32M 1.35 pass 4.9G 32M no matter what vcore/vccin no go max valid 5.1G  i think they doesnt deserve the chance of cold...
