this is my first time overclocking at all and i read up on it and all that and got started, but encountered problems getting past 4.5 stable.
first things first, the rig
case - NZXT Phantom (orginal) with all fan spots full except the 200mm side fan and the front 140mm front fan (front is where i have my kracken so theres a fan but not much airflow)
mobo - gigabyte g1 sniper 3
cpu - i5 3570k with a NZXT Kracken X40 cooling it
ram 2x 8gb team xtreem 2400
psu - corsair HX850 (think i need a bigger one after messing with overclocking lol)
graphics - 2x evga GTX 660 ti (fastest cards they make)
512 gb ssd
ok so i started my setting vcore loadline to turbo and putting memory on XMP to get my ram running at 2400mhz @ 1.65v, then i started with the cpu since i got the others set, first i did 4.2ghz @ 1.25v and seemed stable after running 20 min tests with prime 95 and occt and my hottest core avg about 57c with a max of 64c (occt temp moniter for both tests) then i ramped it to 4.5ghz @ 1.25v and it seemed stable after the 2 quick 20 min test with almost no change in temp readings, i stopped using prime 95 after this because occt tests were working the cpu more. before i continue let me say that my basic understanding of overclocking IB is that the temp is going to set the limits and that much over 1.3v and the heat starts going up rapidly, and that all 3570k chips are a lil different due to imperfections in the manufacturing process. so i then proceeded going up to 4.7ghz @ 1.3v, booted but crashed running occt, went to 1.35v and the same, went to 1.4v and the same, (thought upping volts would solve the crashes), then i went to 4.8 @1.35, booted and crashed during occt, then tried 4.9 ghz at 1.35v / 1.375v / 1.4v / 1.425v, those all booted and crashed either in the occt or locked up before that.
After i hit 4.7ghz and couldnt get it stable i was more jsut messing around to check temps. wat i found interesting is that using occt running 4.7 / 4.9ghz @ 1.4vs is that before it crashed my temps were really low at full load like low 60s avg,
i thought that with IB you would reach the temp threshold well before anything else and that increasing volts increased heat exponentially, i read that much over 1.375 and temps got real hot but i was at 1.4v and still running really low temps.
currently im at 4.5ghz @ 1.25v while i type this and everything appears to be working fine but i want to get over that as it looks like my kracken can easily handle cooling much higher volts, but i cant get anything stable over that, is there any way i can get it faster or am i doing something wrong?
ps i tried typing this up at 4.7ghz @ 1.3v and my browser randomly closed a few times and i noticed 2 of my fans were cutting on and off, but everything is fine at 4.5 ghz @ 1.25v... could it be my power supply not being able to handle the volt increases? also might be why i was running so cold at 1.4v i didnt think to check and see wat my volts were at in occt before it crashed.
thanks for any help
