Hi, anyone wanting to OC or improve it see below -
201/27/2 OC BIOS X58A UD5 REV2.0 / 4.0GHz 4.2GHz Note use this as a rough guide.
BSOD codes for overclocking
0x101 = increase vcore
0x124 = increase/decrease vcore or QPI/VTT...have to test to see which one it is <----- Almost always QPI...
0x0A = unstable RAM/IMC, increase QPI first, if that doesn't work increase vcore
0x1E = increase vcore
0x3B = increase vcore
0x3D = 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
0x109 = Not enough or too Much memory voltage
0x116 = Low IOH (NB) voltage, GPU issue (most common when running multi-
GPU/overclocking GPU)
System Freeze = Usually increase V-core and test for improvement.

A quick guide of how to enable Dynamic Vcore:
1. you need to know voltage needed for your OC under 100% load
2. you need to know your cpu's default voltage (can differ between identical cpu models!)
To find out both get CPU-Z. Load into windows and start CPU-Z, ie > start Linx, when the CPU is at 100% load check CPU-Z voltage. That's your load voltage.
Then go into the bios, set cpu vcore to normal. Lower your multi so you get around 2.8ghz speed at full load (imitating default speed). Boot into Windows
and load your CPU 100% again, check CPU-Z while doing that to find out what is your normal voltage!
Now you're almost done, go into the bios again, set/leave cpu vcore at "normal", go into advanced voltage settings and set dynamic vcore at number closest
to number derived from (VCORE_UNDER_LOAD_OC - VCORE_UNDER_LOAD_DEFAULT)
