right guys Im running my i5 2500k at 4.8ghz per core...


I ran prime blend and all cores were working at the 20 hour point except core 3 which failed at 15 hours.

Is this stable or shall I bump the voltages by one and test again

or am I being too anal about it??? and just consider it stable...
 
You're being too anal.

Fire up your PC and go about your day to day business. Gaming, editing, whatever. If it crashes you need more volts, if it doesn't you're golden.

Running a power virus was never a great way to ensure stability any way.
 
Agreed - its hard to confirm stability without testing day to day tasks. From my experiences I have been fine with Prime95 but received crashes while gaming, etc
 
just try and catch any bsod codes that crop up and adjust if need be

101 bsod is not enough cpu v

124 bsod is not enough cpu/vtt (imc voltage)

it will usually be those two errors or irql not equal which again is usually imc voltage or dram voltage related
 
The is the "most common" list of BSOD error codes.

0x101 = increase vcore
0x124 = increase/decrease QPI/VTT first, if not increase/decrease vcore
on i7 45nm, usually means too little VVT/QPI for the speed of Uncore
on i7 32nm SB, usually means too little vCore
0x0A = unstable RAM/IMC, increase QPI first, if that doesn't work increase vcore
0x1A = Memory management error. It usually means a bad stick of Ram. Test with Memtest or whatever you prefer. Try raising your Ram voltage
0x1E = increase vcore
0x3B = increase vcore
0x3D = increase vcore
0xD1 = QPI/VTT, increase/decrease as necessary, can also be unstable Ram, raise Ram voltage
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)
0x7E = Corrupted OS file, possibly from overclocking. Run sfc /scannow and chkdsk /r

BSOD Codes for SandyBridge
0x124 = add/remove vcore or QPI/VTT voltage (usually Vcore, once it was QPI/VTT)
0x101 = add more vcore
0x50 = RAM timings/Frequency add DDR3 voltage or add QPI/VTT
0x1E = add more vcore
0x3B = add more vcore
0xD1 = add QPI/VTT voltage
“0x9C = QPI/VTT most likely, but increasing vcore has helped in some instances”
0X109 = add DDR3 voltage
0x0A = add QPI/VTT voltage

cheers lads for the advise and bsod codes they come in handy...

its solid as a rock now 21H prime stable at 4.8GHZ

I overclocked 200mhz from 4.6ghz (as my components ie cpu are out of warranty I want to run it to the wall don't care if it explodes now gives me an excuse to get something better) because I got a new GTX 970 so nothing bottlenecks it lol im too anal

aye but im like that just like to get that wee extra out... I test/bench/stability more than I enjoy my PC gaming etc sometimes...

I tried to push for 5ghz but it just wouldn't go no matter how much vcore I threw at it... I lost my nerve before the CPU did lol

Oh well the 5ghz club will have to wait
