Help me get a stable 4.5ghz OC on my 2600k please!

post #1 of 4
Thread Starter 
I'm relative new to OC and I've been reading tons of topics on this site about it so I decided to make one of my own and see if anyone may help me clear out any mistakes I might be doing.

My system is as follows:
i7 2600k cpu
Maximus Gene IV Z
Hyper 212+ cooler
Sapphire 6870 gpu
Antec EW 650w psu
2x Kingston 4gb 1600mhz

I'm trying to get a OC to 4.5ghz as I mention on the title. I prefer Offset mode over manual since it just makes more sense to me (as far as degradation of cpu goes). Even though I plan to game and render on this system, it is most likely it will sit at idle most time when doing stuff like browsing/skyping/listening to music/playing Blizzard games(those don't require much power). So with this in mind I want it OC'ed with Offset.

Doing some testing with prime 95 I was able to figure our my stock VID at 3.4ghz (with turbo off) is 1.236* at idle and 1.241* at load.

I've been attempting 4.5ghz with offset and both LLC on/off (off/0%, on/50%/75%/100%). C1 is enabled, c3 report and c6 report is disable and package c state limit is set to no limit always. Using T. Probe or Extreme Vcore PWM mode setting. Vcore Phase always at optimized. I haven't touch PLL voltage (auto). When trying offset mode at - 0.05v I get prime95 blend to run for an hour at 1.336v and get a BSOD 0x00000124. Then I tried -0.025 to get 1.361v and after an hour it BSOD'ed 0x00000124 again.

I feel going for higher seems too much, specially for a mild OC like 4.5ghz. Another user has gotten 4.5ghz offset with 1.28v! I know each processor is different, but i think a .1v difference (at this rate) is too much.


*VID I got from Core Temp, the other v's I got them from CPU-Z

Anyone has any suggestions?

my cpu requires 1.4v to be 100% rock solid stable at 4.5ghz, and requires 1.5v to hit 4.8
