Desperate For OC Help

post #1 of 5
Thread Starter 
Please someone help a fellow Intel noob out and assist me to get my overclock stable or at the very least determine if my chip is just a dud. I have been trying relentlessly for a couple weeks to get my 2500K overclocked to 4.7 to no avail. As you can see by my sig I did have it stable at one point by running Prime 24 hours but one day all of a sudden computer shut down and I have been unable to get it stable ever since. Here's a rundows of my BIOS settings to start:

I disabled C1E, C-states, & Speedstep
I disabled Spread Spectrum
I enabled PLL Overvolt
Turbo is set to 200, 200; Core limit is 250
I am using a fixed voltage (I already tried offset) 1.385v
LLC is set to level 3
Everything else is set to auto

I'll just explain my most recent attempt. I recently ran Linx with AVX and passed 25 runs; I then proceeded to run Prime95 on blend but got a rounding error (0.5 expected less than 0.4) after 15.5 hours. I then restarted Prime and ran small fft for 8 hours and pass. I ran large fft for 13 hours overnight and pass. I then run blend once again and 3 hours in I get a BSOD with error code 124. That brings me to posting this thread. I really am beginning to believe I have a dud of a chip, it requires an insane amount of volts to hit clocks that others are getting with or near stock and I keep getting errors.

At this point I'm stumped, I am really not wanting to add anymore vcore because I am worried about setting it too high and also my temps start to get a little high for my liking. I am not sure about the other voltages so I just leave them on auto but have been reading about VTT but not sure if I should mess with that or not. I am just about ready to try and RMA this processor but it's very hard to prove a defect in a CPU. Perhaps my it's my generic DDR3-1333 cl9 RAM holding me back? I tried running memtest and when I check computer after awhile the screen looked all garbled (see pic below).

Anyone have any ideas? I'd appreciate any assistance. Thanks in advance!

My best suggestion is to find some compatible known good donor ram and run cpu torture test again. If your memory test is corrupting, then your ram is possibly the culprit. If you don't have access to known good ram, pull a stick (doesn't matter which one) and run just a memory diagnostic. if it passes, replace the stick that's still in your machine with the one you pulled and run memory diagnostic again. if that passes, then move on to cpu. Prime small fft's are good to diagnose cpu stability with little ram tested. Large ffts use a little more ram. blend uses even more ram. What got my attention is your first 15 hour run on blend. then your last 3 hour run on blend with bsod. both instances of failure were on test that uses significantly more ram.

Disregard the part about my RAM, it was a bad download and burn. I redownloaded and burned using a fresh disk and it worked and passed no issues.

I should clarify it was memtest that passed so I don't think it is a RAM related problem. I believe it is CPU or voltage issue.
