sin0822 Posted January 4, 2012 Posted January 4, 2012 your other BIOSes lack internall PPL overvoltage? Quote
hokiealumnus Posted January 4, 2012 Posted January 4, 2012 Shamino said it is a useless option and has never helped. They put it in there so you can find out for yourself, but on or off it hasn't helped him. I haven't had the chance to try it, but I doubt my brick wall will move; heh. Quote
sin0822 Posted January 4, 2012 Posted January 4, 2012 ah ok. yea it didn't seem to help on the GB boards I have. I was told tho, it helps at 5GHZ+ a small bit, like raising your CPu PLL Voltage. Im go subzero when i get some time, maybe ill test it out. Quote
nedernakker Posted January 5, 2012 Posted January 5, 2012 only thing it did fot me was giving me the 'unstable due to unsuitable conditions error message' and no matter what clock gen filter I applied, my system wouldn't boot unfill I turned the PLL overvoltage option to disabled Quote
SoF Posted February 22, 2012 Posted February 22, 2012 (edited) maybe others of you can check that: booting high bclk will often end in "79" specially when it reboots after raising the multi. best way to work around it with fresh bios: load bios profile, save and reset set 125 strap / 125 bclk set final voltage and multiplier to 32 (as this will always boot), reset set 35x multi and reset now set 40x or higher and keep fingers crossed it will not reboot if it reboots 80-90% chance of 79... anyone else?

SoF Posted February 22, 2012 Posted February 22, 2012 I mean booting with 125 strap in general to be specific - doesn't matter if 125 or 128 bclk as far as my tests are going... Quote
Hiwa Posted February 22, 2012 Posted February 22, 2012 I mean booting with 125 strap in general to be specific - doesn't matter if 125 or 128 bclk as far as my tests are going... mm i don't have this problem i boot all the times 129 x 42 Quote
SoF Posted February 25, 2012 Posted February 25, 2012 got my 3960X (maybe C1 not sure) and don't have the problem anymore. but I benched with singlestage the first time this night and after ~6 hours the board did some crazy thing. while running 3DM06 at 1.6V it suddenly gave +0.15V for no reason and I ended up running the CPU Test with 1.75V it wanted to raise the voltage even further until I shut it down. Stock voltage after cmos clear was 1.45V... Needed some more reboots until it went back to normal...very strange...could bench another 2 hours afterwards with no issues. Then warming up, benching again, after 2 hours the same issue...it was early morning by then so I decided to leave it alone for a while... Quote
Crew Leeghoofd Posted February 25, 2012 Crew Posted February 25, 2012 dangerous stuff there SOF Quote
Massman Posted February 25, 2012 Author Posted February 25, 2012 Are you running the highest value of LLC ? Quote
SoF Posted February 25, 2012 Posted February 25, 2012 Are you running the highest value of LLC ? usually running medium or ultra high. got my 3820 today but seems to suck (40x126) and additionally my windows freezes all the time when I want to check GPUs... I think I will only check to get it back running, sell a card and wait for ivy Quote
subaruwrc Posted March 13, 2012 Posted March 13, 2012 is it possible to have a clock wall at 5330mhz on this board? I've tested to different chips on ln2 and both of them maxed out at the exact same frequency of 5337mhz 6c/12t which leads me to the idea maybe I mess something up in the bios settings. The 1st chip is a 3960X engineering sample which has the same FPO as Massman tested, and his cpu maxed out at the same clocks. The second one is a retail boxed 3930K C2 chip. So is it possible to "find " another 70 stable mhz to minimally statisfie my needs or just live with it to have 2 sb-e cpu-s with the exact same max frequencies? In offtopic the C2 chip is a piece of ....... stability wise, the ES was a lot more relaxed, and kept the setting throughout 4-5 hours straight, while the C2 b1tch had to be finetuned at every damn boot process, and froze a lot, even at settings which were stable for 2 hours ..............

Massman Posted March 13, 2012 Author Posted March 13, 2012 It's, imho, more likely that you just found two similarly clocking chips than your board having a clock wall. Quote
subaruwrc Posted March 13, 2012 Posted March 13, 2012 I thought so. I will try to squeeze out at least 20-30mhz more but not too many options. Vcore don't help. Maybe a good combination of vrm settings, and high pll voltage will result in 5330-5350mhz stable. The cpu's are not bad temp wise cause both of them can bench at -70 or lower and boot with streched imc at - 63c. To tell the truth the lack of raw cpu mhz is not the main and only problem, the worst part is that i got results similar to 5-5,1ghz cpu-s at 5.3 ish.. Quote
Massman Posted March 13, 2012 Author Posted March 13, 2012 Try to run at -20°C or so. Most of the chips I've tested cannot handle cold very well. Especially the IMC tends to dislike it. Quote
subaruwrc Posted March 13, 2012 Posted March 13, 2012 Yeah i had the same feeling, that it can run at -70 doesn't equal to It likes that temp so next time I will try to play at higher temps, but with -20c on the pot I think is a bit to high. It can be + temps under high loads no ? Had a 5.6ghz 2500k chip ( dead by now .. ) which was able to run down to -80-100 but liked -50 the most and gave me + 200mhz lol. hopefully sb-e will react the same. I just want to play safe and not burn the mobo. . Quote
