check ur QPI multiplier 1st maybe ??? 

OK guys, I have a problem in using bclk 200MHz.

I can get my 197MHz x 20, Vcore 1.27 Bios (1.31 CPU-z), 1.31 VTT and 1.65Vdimm pass Linx 20 runs no problem.

But yesterday I tried 200MHz x20,x19 and x18 but couldn't get it to past limx for more than 50 seconds.
I pumped the Vcore until 1.32v but got nothing, then I push the VTT to 1.37 (Vdimm 1.68 constant) but no improvement whatsoever.

The thing is, no matter what settings I use, if it involves 200MHz bclk then my screen will freeze after running Linx for 30-50 seconds.

I tried one of the bro Cstkl settings but it improves nothing.
Again, the screen freezed on my initial run for the first test. It's the same all over again~

Everything done on my DK in diagnostic mode.
i7 920 D0 with megashadow Push/pull, 6GB Dominator 1600MHz cl7 ver2.2, DFI DK, HD5870, Acbel M8 750w.

Err. I'm kinda confused here. What do you mean by that. Enlighten me please~

geng use more ram

trust me..
if u run in diagnostic mode with nothing on .. u can linx around 5518

this is like freaking hard..
i can pass like 5400 etc for 100 runs
but will hang on this sometimes on 3 run lol..

and normally tweaking minor and ram settings etc..

Try this:-

Enable "Load-line Calibration" thingy IF avail. in BIOS
Set IOH & ICH to 1.2V for both
QPI Voltage to 1.32V raise again IF fail by 1 stage, or just shoot for 1.35V..   
VDimm just need around 1.64V

can u show us ur CPU-Z ? just capture the memory and cpu portions. 

I'm sorry but can you explain to me the logic of pushing the IOH and ICH voltage? Thanks~

until now on 4 different boards
i never hard to raise ioh voltage until 215
even on sli, crossfire etc

turn off temp protection on cpu.
burn mark.
clear.
good luck. 

If it overheats to be dead, probably there would be irremovable marks that can invalidate warranty right? Not a good idea 

Bah, bad idea. I'll just live with the faithful i7 920. It is so tough that it can take any abuse.

@gengstapo

nice clock there,what rams are you using..?

try and push your rams too..

are you on wc..?

Hi all,
I'm new to OC here. Had read few forum about OC'ing i7 and thinking of doing it this weekend. Below are my desktop's components

i7 930 (CPU cooler - VX w/ a 12cm cm fan)
P6X58D-E (BIOS ver 0303)
Corsair (3X2) - CMX6GX3M3C 1600 C7
Casing - CM II 690 Adv

first of all, I would like to know are my cpu's cores temp normal. Everything on stock and not inside AC room.

realtemp reading (w/ HT)
low              high
44                45
39                40
43                44
41                42

I did tried to disable the HT but I just can see the difference of 1c for all the cores compare to w/ HT.      is that normal ???
Need some advise here 

The core temps look quite normal at idle state.
They're relaxing when idle ~0% proc usage be it w/ or w/o HT
Once load u will see a huge difference.
