2600K, some advice on short/long duration power limits, and vrm fixed freq's

post #1 of 3

Okay, so currently, I can attain 4.6ghz on my 2600k that is 50 pass IBT stable, as well as 16 hour prime stable at 95 percent memory used. My gear is in my sig, here are the wave tops:

to hit 4.6 ghz-
-cpu at offset -.005
-load v-core in IBT- 1.376
-temps- high of 75 in IBT, 71 in prime
-Ram- gskill sniper 1.25v 1600mhz (overclocked to 1866 and 1.35v 10-10-10-25)
-VCCIO over volted to 1.14 to keep the 1866 memory O.C. stable
-LLC on extreme (whatever the second highest was I cant rememeber)
-c3/c6 disabled
-CPU current capability 130%
-PLL over voltage disabled

I just cant pass 4.6 for the life of me. I was testing at 4.8 earlier, and got to 49 passes of IBT (of the 50 I set it for) and it failed. Maybe a fluke? The offset for that required +.030. I figured, okay, it gave me a bsod 101, so Ill go to +.035 offset, but it failed much much quicker.

I'm wondering what kind of difference the VRM fixed freq makes on stability/temps etc....currently I have it at 350, but it can go as high as 500.
Also, what difference does the short/long duration power make? Currently, they are both 250.

At anything past 4.6 ghz, I must enable internal PLL over voltage. in order to get it to POST or be worth anything in windows.

Any thoughts? Let me know if I left out any pertinent details. Thanks.

Just attempted 4.8 on even higher offset, +.040, and a BSOD. none the less, inconsistent results so Im sure the solution cant be more vcore, since sometimes it makes it many runs on IBT, sometimes it BSODs. Load vcore was 1.426 in IBT. This is getting to the upper end of what I would like to have, so I may just back off now and keep her at 4.5ghz @ 1.344 under load to keep longevity.

Bump...anyone help me get over this wall? Would spread spectrum being on auto be holding me back? Which is better for high overclocks?
