Im getting BSOD's now
0x000000000E1 what does that mean?
where do I start with PLL, VTT, and IOH voltages?

That's a memory-related BSOD. You are still running it at stock timings, speed, and voltage, right? If so, increase IOH voltage and retest. Again, you're looking for a change and not necessarily for a complete fix with one small voltage increase. If it lasts longer before BSOD, then you're on the right track.

Okay, ill try that, VTT = QPI/DRAM core Voltage right?
which is my true vcore? CPU-Z says: 1.288V and BIOS I set it to: 1.3V
CPU @ 4GHz

Okay, QPI/RAM core voltage(VTT) should be 0.5V from Vcore? when I enable XMP on the Memory it sets my Vdimm to 1.65 ,which is right, and VVT to 1.4V, intel recommends 1.35V to be safe

does that mean I need to set VTT to 1.4V as stock? and then Vcore to 1.35 because its a 0.5V difference

because with 1.35V vCore, I can OC the CPU to 4.2Ghz stable,
temps touch 80C normally stays 78C in prime95

Ill set IOH to 1.2 and then try test from there.

Lastly,
I've got cas9 RAM can I overclock it to cas8?

I payed for Dominator 2000 cas8 RAM, but got 1866 cas9 RAM, because shop was out of stock, is it worth getting the 2000 cas8 over my current RAM?


My end goal is to run the CPU @ 4Ghz and RAM @ 1600+ cas9 or cas8

Just I got a BSOD with IOH on 1.2V and ICH on 1.2
I set PLL to 1.88
Vcore: 1.3 (1.288V) CPUID
VTT/uncore: 1.35V
should I mess with PCIE voltage?

what should I increase? what BSOD's errors do I look out for?

Also, how would I know if a GPU overclock is stable? I should I leave a GPU overclock for know?

those SB chips look sweet, wonder what they'll cost here in SA, prolly much more than in US
overclocking them isnt as fun I see.

Most common if you haven't messed with timings will be 101 for too little vcore a d 124 for inappropriate vtt. Too little or too much. If you're looking at 1.35vtt / 1.4vtt you should be okay.

WOW, I just turned off Hyper threading, because it doesnt impact game performance

and I'm just amazed at the temps, Im running 1.32V @ 4.1Ghz prime95 stable and temps are high 60's hitting 71 max + ambient here is 26C, today was 36C! I cooked

I could prolly go 1.35V 4.2Ghz, thats the highest ill go with volts for now. altough the shop had it @ 1.4V ;/ new inspiration to start OC'ing again

I did some of my own testing on Call of duty Black Op:


RAM - 1750Mhz
CPU - 4Ghz [HT On]
vcore: 1.3V in BIOS 1.288 CPUID

Black ops FPS: 90 FPS [I picked I specific location on the map cracked that stresses the the hardware] normally see 125Fps solid


RAM - 1790Mhz [ a bit higher]
CPU - 4.09GHZ [HT off]
Vcore: 1.3V bios 1.288 CPUID

Black ops FPS: 95 FPS

bottomline: HT off for gaming, get the extra Mhz in CPU and RAM to get a few extra FPS, same conclusion as the previcous link I gave
