Is my 2500K just a dog?

post #1 of 33
Thread Starter 


It won't boot to windows on anything less than that at 4.4 GHz. 4.0 GHz requires 1.20 VCore.

I'm running an AsRock P67 Pro 3, same UFEI BIOS as the extreme version.

When increasing the multiplier, windows bluescreens with an error code of MACHINE_CHECK_EXCEPTION Stop Code: 00000000x9C. I increase vCore, up until it goes away. It seems stable then, each time this happened (when increasing multipliers), as soon as I had a vCore that could get into windows it was stable for 25 IBT runs, and ~2hours of Prime, at which point I just stopped them.

Here's the settings I'm using in my BIOS.








Is my chip just a slow dog, or am I doing something wrong? I see some many people hitting 4.5+ on under 1.25 vCore.

PPL Overvolt enabled.

All power saving options (C1E, C3, C6), enabled. Set short and long duration to 200, Core Current limit to 300. Leave voltages on Auto unless your ram needs more juice. Vcore @ 1.4, multi to 46-48

No all chips are different I am at 4.5GHz and it requires a wopping 1.355v to get stable. I seen another guy with same speed as me and he required 1.37v to get his stable.

Also if it was vCore bsod I think it would be 0x000000124 might want to search around for error codes could be something else.

Correct me if im wrong but options like ce1 and other power modes should be disabled.

is your dram voltage stable? on my motherboard i have to set it to 1.55v so that it is at 1.53, if i set 1.5v it drops to 1.46. Also enable C6 and C3 and internal PLL overvoltage. I hit 4ghz with 1.05v on my 2500k.
Also why not just overclock the turbo and not the main?

Sig has my voltage settings.

On your MSI, sure

Yeah all boards/CPU's are different. I'm able to get 4.5Ghz with only 1.3v.

As far as the power saving features; I think there is some truth to leaving them enabled for some, but AFAIK, I don't have them enabled. I'm not at home so I can rightly check, but I'm pretty sure I wanted my OC to stay on all the time, so I turned off all power-saving stuff.

so is overclocking the turbo (which is only 2 cores when it kicks in) better than the main? I'm planning to do a sandy bridge build later this month.

What the heck is PPL overvoltage?
Do you mean PLL overvoltage? or is PPL something new?
