When running Linx or IBT the GigaFlops have to be close to the rating for your particular chip. If it isn't then, you're not stressing the Overclock correctly.
After I loosely followed this guide my GigaFlops increased dramatically and my core temps rocketed by 5°C Luckily, I had previously increased my vcore and my qpi voltage due to Prime 95 Bsod after 8hrs. I now feel that if Linx is run properly, it will tell you if you're overclock is stable within 99%, I would guess
I found these here on OCN and I feel that the above and these should be added to the guide.

BSOD codes:
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
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)
Thank you for those codes and what causes them. knowing what the rest of these are caused by will help Overclockers like me get past 4GHz

This is great! +1 to you bro. It would be nice to add to this, I wish I could offer some additions to this right now.

I've noticed with my overclocked settings that the voltage stays at or pretty close to 1.28, where as with stock it would fluctuate from 1.20-1.21 and pretty close to 1.0 when idle.

Obviously this is from setting the Vcore to 1.28 for my overclock. However is I set it to auto with the bclck at 160 the voltage goes as high as 1.4 which at this point is undesirable.

Is there any way around this? Is there a setting I can modify to get the voltage to idle when cpu power is not necessary? My settings are a couple of pages back (pg 110) but here's the main ones just for recap:

CPU Ratio: Auto
Turbo: Enabled
BCLK: 160
DRAM: 1282
QPI:5774

Voltages:
VCore:1.281
PLL: 1.84
QPI: 1.30
IOH:1.2
ICH:1.1
DRAM: 1.64

LLC: Enabled
CPU Diff amp: auto
CPU clock skew: 100ps
Anything spectrum: Disabled

CIE and C-State: Disabled
Virtual: Enabled
HT: Off
TM:Enabled

I would try raising your cpu VTT as you dont seem to have done anything with that. VTT is for the ram controller, and should be within .45v of Vdimm for best results


VTT is the same as QPI voltage correct? I did raise it as high as 1.32 but couldn't get a stable 1600 memory speed, I'm stuck with 1282 for the time being until i've had my system a few more weeks and decide to up the voltages a little bit.

I've noticed that most of the time if I get a 0x101 BSOD it shows up as 0x124 in blue screen viewer, anyone know why this is?

Please add PERSPOLIS's How to run linpack to the LinX section of your guide please.
https://www.overclock.net/intel-cpus/645392-how-run-linpack-stress-test-linx.html
Thanks to everyone for the reps, but all I was doing was repeating info that I found on the forums. I would like to credit the original authors, but I don't know who they are.

Disable the turbo and try it again and see if it goes to 1.4

nice guide. nothing is perfect but there is definitely a lot of good reference material here. I don't have the money for a great cooling system or a new case right now so i am trying to get a small boost without killing my system and you seem to have helped a lot.biggrin.gif

That's a negative. That board is an 1156 socket.
