System specs : Asrock z77 pro3, i5-3570k h60 cooler, 8gb g.skill ram @ 1333, corsair 600 psu. gtx 760.

Ok, so I've been playing with my overclock a bit and I've been getting a bsod occasionally and the code is usually either 124 or a, which from what I understand correlates to vcore, just from what I've read on another forum, which states that's usually what it is if your hardware is good, I've tested my hardware and from what I can tell it's all solid. Now, with my overclock I've got it at 4.5ghz with an offset of .025 with full load temps only reaching 58 degrees max c. My vcore at idle is 1.224, under full load in prime 95 the vcore drops to 1.160 and I believe this to be the cause of my occasional bsod. I have my load line calibration set to 100% and VTT increased to 1.085.

I know there is a term vdroop but i'm having trouble understanding it and understanding what I need to change to get my overclock stable. I've ran prime95 for 5-6 hours with no bsod but then I go to sleep wake up and bam bsod error code 124, or 0A. In my opinion my temps are great and the voltage I couldn't be happier with but the drop in voltage doesn't make sense to me along with the voltage drop. I understand the pro3 isn't the best for overclocking but I seem to be doing ok other than this bsod. Does anyone have an idea as to why this is happening, or what I need to change?

Ah ok, see how you go with the RAM settings manually set, if you still get the same issue then up the offset voltage a notch or two.
Hi,

Vdroop is in very simple terms the difference between your idle and load voltage. You can reduce the difference between the two with LLC however you already have it set to 100% so if your CPU needs more voltage under load then you'll just have to increase the offset voltage.
Have you manually set your memory perimeters (voltage, frequency and timings)?
Also do you get the BSOD's when the PC is under load or when idle?
It might actually be the change in freq. and voltage that is causing the instability, you could try using a fixed voltage and disabling the power saving features of the CPU (C1E, speedstep, C states ETC...) just as a test to see if that is the problem.
Anyway just some thoughts.

I have not set the voltage, freq, or timings, the stock voltage for my ram is 1.5, and timings are 9-9-9-24, freq at 667. I've disabled all powersaving options. Based on this it could be my ram causing instability?
 


Well it could be and people often forget or don't realize they need to set those values so thought I'd mention it.
Have you tried a fixed Vcore rather than offset?
