Hey guys, i just got my rig a few days back, and I'm planning to overclock it to around 4.2GHz, maybe more. Can anyone help with what i have to do? Sorry, I'm a novice but I can learn fast.
My specs are:
CPU- Intel i5 3570K
MOBO- ASUS P8Z77-V
RAM- G.Skill 4GB DDR3 1600 F3128004GBXL
GFX- ASUS ENGTX560 DC
PSU- Antec HCG 620
COOLER- SINGLE PUSH FAN Cooler Master Hyper 212 EVO
CASE- Antec DF-85

go into the overclocking section of your bios, raise the multiplier until the clock speed hits 4200MHz, and raise the voltage until its stable, you may want speedfan, or HWmonitor to watch your temps (you dont wanna go much above 70C on the cpu)

and use prime95 to test for stability, use the small ftt setting

Will changing any voltages other than the Vcore improve stability? Also what is the max voltage that I can safey set the Vcore to?

i would say don't go above 1.325V, and yes, a higher Vcore is more stable, but if its stable at a certain voltage, don't put more into it as it will create unnecessary heat

Well I've overclocked my CPU to 4.0Ghz, with automatic offset voltage. It's been stable for few hours on Prime95 Small FFT. The VID is at 1.2360V according to Coretemp, and the voltage reading is 1.168V according to CPU-Z (means my offset is lowering the voltage right?) But one thing i noticed, when I'm Prime95-ing, the Voltage goes to 1.168V, but when I'm not doing anything, the Voltage goes up to 1.22V. Is this normal? Could someone explain to me how to insert JPEG's? I honestly don't have a clue :pt1cable:

You should raise llc(load line calibration) to lvl 3 or 4(asus is high or ultra high) it will reduce the gap between bios Voltage and Cpu-z reading and also put asus phase control to optimized.
I would try with a negatiive offset "-" 0.05 v and decrease rinse and repeat it until you get the lowest voltage and stable with intel burn test at maximum for 5 run when your set test it again but for 30 run with core temp to monitor heat and cpu-z for voltage.

Well, I listened to you about the LLC, I raised the LLC to Lvl 3 using AISuite 2, but I've found that on load now, the voltage goes up to 1.21V. When I set the LLC to regular, the voltage goes to 1.168V on load. When overclocking, don'y you have to try and get the highest clock with the lowest voltage? Oh and I set the phase control to optimized, but I didnt change the offset value, I left that at automatic.

EDIT: I've set the multiplier to 43x in the bios with a BCLK of 100MHz so I'm at 4.3GHz, when I ran Prime95 (Small FFT) afterwards, my voltage shot up to 1.32v and temps went up to about 68Celsius. However, using TurboV EVO, I managed to lower the CPU voltage reading in CPU-Z to 1.168v without BSOD's, so is that good? Temps on load are now: 54, 54, 55, 59 (degrees Celsius). So does anyone think it would be safe for me to clock the CPU higher? up to 4.5GHz?
