Increase vCore 1st, followed by vQPI (VTT) and vDIMM.
Google for BIOS settings

for i7, you need higher vcore for 20x multiplier. you can try 21x multiplier to get lower stable voltage.

I think u can directly contact intel for the warranty claim. where did u get it from? just send it back to the shop

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.

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..

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

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..?

Thanks for the input.
So those temp are normal. I have ran prime95 blend test for 10 minutes and the temp were WOW 

realtemp w/ HT (full load)

72
70
70
69

I think 75C is the CPU threshold right? 
Just want to know is it save for me to OC to 3.2 first on this weekend ? due to the heat 

tailo kevin i wanna ask somethin.
why my 930 idle temperature are about 56c?
im just use stock cooler and using tx2.
edi turn off ht
fyi when i assemble my rig i ter drop my proc about 15 cm high and back of the proc kene lantai
is that cause this prob?
using giga x58aud3r mobo and pls recommend me bios setting for this mobo for 4.0ghz speed.

ur dram timing should be 9-9-9-24-88-1T
and run LinX to the max memory in normal mode or full amount in diagnostic mode
max memory settings, click "All" button or pick the last memory size option from the drop down menu, the "All" option is highly recommended
20 runs should last about 1 hour
for diagnostic mode, go to START menu > Run (or hotkey win logo + R) > type msconfig > diagnostic startup

Slower QPI mode could help in achieving higher BCLK, easier.
