i5 2500k overclocking proving to be a nightmare :(

post #1 of 99
Thread Starter 
Hi all,
I recently built a new gaming system
i5 2500k
darkrock advanced cooler
corsair 600t white case
corsair force 3 ssd
seagate barracuda HDD
Corsair HX750w PSU
MSI 560 Ti HAWK GPU
Gigabyte z68xp-ud3p MoBo

it's proving to be a nightmare to get a stable OC especially the desired 4.5Ghz i've tried lowering CPU PLL to 1.7, raising the VTT, load line calibration level 4 seems to be the only one that even remotely matches my bios setting on load. i've gone all the way up to around 1.36vcore with 1.12 VTT 1.7 PLL i really don't think i should need more than 1.36vcore for a stable 4.5ghz overclock. i'm even happy with 4.4 but no luck frown.gif

the only thing i haven't tried enabling/changing is internal PLL voltage setting so should i do this?
currently testing stable with default settings with just a 40x on the multiplier but that gives me 1.31 vcore which is silly for a mere 4ghz overclock

generally just wanna get your advice on the situation since this is my first overclock and you guys will know what you're doing far more than i do

thanks in advance

Leave everything on auto except the Vcore, 45X multi and change Vcore to 1.30v

I have corsair vengence white 1600mhz at 1.35v

One other thing i saw a post which confused me. do i change the clock ratio or do i change each turbo to 45??

cheers

isn't the voltage of the vengeance is supposed to be around 1.5v?

Vcore around 1.5v? Only if you wanna melt ur CPU m8.

All I did for my 2600k which is technically tougher to OC with HT and 16Gb of RAM, is lower timings to 1333Mhz for RAM, and up the multipliers to 45, upped Vcore to 1.34v and ran stability tests. Never touched PLL and the other functions.

yes all vengence kits are 1.5 except the white LP edition which is guaranteed to run 1600mhz 9-9-9-24 at 1.35v

this is what i have currently set based on some reading i did today.

clock ratio 33 (default)
turbo enabled with each multiplier set to 43
core current limit 200
cpu power limit 100 amps
C1 enabled
C3 disabled
EIST enabled
LLC level 4
Vcore 1.32
VTT 1.12
CPU PLL 1.71

alright, the only thing i can think of is leaving everything alone and only change the multiplier to 45 and the vcore. I have mine stable at 4.5ghz with 1.34v without changing anything, except for setting load line calibration to very high.
