unstable 4.2????

post #1 of 12
Thread Starter 
ok, OC'd my 2500k to 4.2 thinking that it would be an easy OC to reach, and that its plenty enough to game on...i dont beat it to benchmarks so i dont need 9.7 gigglehertz.

ran prime 95 torture, blend, small and large FFTs...all stable and my temps never break 47-48.
gamed like crazy with metro and mafia 2, no problems at all, temps of course barely rise.

decided to test with OCCT linpack and linx....both error out relatively fast. OCCT lasts for 5-6 minutes before stopping and linx makes it 2-3 runs before stopping. i am at a loss now....i thought all was gravy but i guess not?

i am OCing on a biostar board, so things like LLC i dont know how to properly set, because it uses voltages instead of "high" like other boards....any help is greatly, greatly appreciated....

this is my first OC, so tell me what i dont know skrate up.

give it a touch more voltage and see what happens. a .02V offset should be goof in LLC

ok, going to have to wait a few more minutes to do that....my wife decided to upload a video on my PC instead of hers...so, gay.

so, try upping the LLC voltage .02 and see if that is stable?
can you explain to me what the LLC voltages should be around based on what the vcore is?

LLC voltage is voltage to add if your CPU voltage drops

ok, then my understanding was correct.
also, my current vcore is set @ 1.29, so theoretically shouldn't that be enough?

are there any other settings i need to look at?

could the linx fails after 5-6 runs be memory related?
i down-volted my xms3 from 1.65v to 1.5v and kept the stock timings/speed @ 999-24/1/1600mhz

yeah, that is looking like what the issue is, playing with settings right now.
upped the voltage to 1.55 and made it 11 runs in linx before bsod.
as of right now, is 1.6 dram safe for sandy? i have heard that people run 1.6-1.65 with zero issues.

1.65 will work fine. The reason someone would want speedy memory with lower voltages is for more overclock headroom. You wouldn't be able to run your memory much faster or lower the timings much because you're already at 1.65.

If your memory ran at 1.5 at 1600Mhz, you would have more room there. Since you're not into benchmarking your memory will be just fine. Just set it to the voltage Corsair calls for.
