Still not stable

post #1 of 47
Thread Starter 
This is about the 3rd or 4th thread i've made claiming my overclock to FINALLY be stable, yet it's not........

I've reverted to manual voltage, and could run IBT until pigs grew wings, but there's something FFT length 1344 that gets my system everytime,

IBT can pass 50 runs no problem, cpu-z reports 1.31volts to do this,

prime95 fails on the 3rd or 4th custom test (fft 1344, ram 3gig)

i bumped up the voltage and im currently sat on 1.344volts hoping i dont get a hardware failure again, how can it be that a certain FFT requires at least 0.03volts more to be stable?

What do your other settings look like? I was also having stability problems at 4.5Ghz and lowering the PLL voltage from 1.8 to 1.74v fixed the problem. May be worth a shot.

default / auto, i've tried raising every single voltage one by one, and now that i've clearly overvolted for the 1344 FFT it's up to test 10 at the moment when before it didn't even reach 5, apparantly 1344 and 1792 are the hardest for sandybridge to pass, but why i need to bump the voltage 6 notches up seems a bit over the top ...

Those two tests are indeed very difficult for SB CPUs. The solution may actually be a decrease in voltage Lowering PLL voltage below stock has worked wonders for many people here that were stuck on a few Prime95 tests.

1.344v for 4.5Ghz is not great but it's not horrible either. You can most likely lower that with enough experimenting.

i'll give it a go, i did get up to test 17 at current voltage though so if all else fails i guess i'll just have to let my cpu burn for its ways and ramp up the voltage

edit: bsod at 2nd test, worse than before! i did get a 101 this time even though it's been 100% 124's before

As for overclocking your chip, the best advice I can give you is what I did in my BIOs to get my chip to run at 4.5 at 1.29..

-Internal CPU PLL Overvoltage = Enabled
-Real-Time Ratio Changes in OS = Enabled
-Intel Turbo Boost Tech. = Disabled
-CPU Enhancement Halt (C1E) = Disabled
-C3/C6 State Support = Disabled
-CPU Thermal Monitor = Disabled
-CPU EIST Function = Disabled
-Multi-Steps Load-Line = Level 6

-Vcore manually set at 1.295
-Downclocked 2133 RAM to 1866
-Manually set RAM voltage to 1.505 (Regularly at 1.500)

Before I did all this I had to run AT LEAST 1.43 Vcore to get my chip to run at 4.5Ghz, after doing all these tweaks, I got a little over 50% drop in my Vcore, making my temps a lot better, and a peace of mind for myself, and my chip.

the thing is it's just these 2 tests that it wont pass, i can run 1.31v fine through IBT and the rest of the prime tests, but with these 2 it needs to be really pumped up,

i basically have what settings you describe dustin, except the extreme LLC and PLL (i use sleep a lot), i've tried every setting the motherboard has but the only cure seems to be MOAR VOLTS,

it's just silly that 2 specific tests make the whole thing fail

Did you manually enter your ram timings? Many motherboards are unable to properly detect the exact timings when set to auto.

yes 9-9-9-24 at 1.5volts (rest auto, i assume,), ram's fine, passes memtest, i've tried 1.6v on the ram, ive tried downclocking them to 1333, i've tried the VCCIO volts to 1.15, i've tried power phases, spreadspectrum, pll voltage, LLC off / on, c1,c3,c6, speedstep, nothing works except a crap load more volts........

time to get a beer, this is gonna be a long night

my last hope is extreme LLC, but i'm doubtful
