Sandy Bridge BSOD

Processor is overclocked to 4.5ghz @ 1.35v and GPU is overclocked as well. Recently installed a new soundcard and 2 new hard drives and put them in a mirrored volume using Windows disk management. Since then been getting this bsod about once a day.

Here is a picture with the error codes

Hello,

What is the make/model of your PSU?

I suggest you reset the overclock for the time being, let's see what happens.

Corsair HX1000, i didnt want to but i think i will need to take some time and reset everything back to stock to find the issue.

Have you run any stress tests on your overclock? You must do this.

A BSOD of 124 usually means you need to increase/decrease (usually the former) either your VTT (aka QPI or IMC) voltage or your CPU core voltage. To find out which, run PRIME95 with small FFT for > 3 hours. Since the small FFT can can run within of your processor cache and won't use RAM, if it fails it is your core voltage. if it fails increase Vcore until it passes, then run blend test and teak VTT/QPI/IMC voltage until it passes.

I find this BSOD almost always indicates a need to twea VTT/QPI/IMC voltage.

Here are general guidelines for overclocking BSOD:


BSOD codes for overclocking
0x101 = increase vcore
0x124 = increase/decrease vcore or QPI/VTT...have to test to see which one it is
0x0A = unstable RAM/IMC, increase QPI first, if that doesn't work increase vcore
0x1E = increase vcore
0x3B = increase vcore
0xD1 = QPI/VTT, increase/decrease as necessary
0x9C = QPI/VTT most likely, but increasing vcore has helped in some instances
0x50 = RAM timings/Frequency or uncore multi unstable, increase RAM voltage or adjust QPI/VTT, or lower uncore if you're higher than 2x
0x116 = Low IOH (NB) voltage, GPU issue (most common when running multi-GPU/overclocking GPU)

Sorry about this Geno, but that list is highly inaccurate; we've seen it before. See here: BSOD & ntkrnlmp.exe - Tech Support Forum

Since the BSODs started after a sound card and hard drives were added, it seems the problem is probably related either to a power problem or the devices itself. It won't hurt to run a stress test though.

I will try prime95 and memtest and get back to you guys. Thanks

It might not describe the type of BSOD correctly, but I found it is usually spot on on the cause when the BSOD is due to overclocking. If you are pushing overclocking, you'll hit about every one of those BSOD I listed. The descriptions in the thread you pointed to are useless in determining what to do when you get a BSOD from overclocking. If the OP has not tested the stability of his overclock, then the addition of the hard disks could be just a coincidence. 4.5 GHz is a large overclock, even for a Sandybridge and may neve have been stable.

With a BSOD on a heavily overclocked system the first thing to rule out is instability due to overclocking.

When you run the blend, run it custom using about 4GB of memory and a large max fft size (say 10000 or bigger. That will give the memory a good exercise. Also., make sure you have "check rounding errors" checked in the advance tab of PRIME95.

A quick alternative is to back off on your overclock to see if the problem goes away.
