i7 920 D0 @ 4.0 Stable With a Gigabyte UD5 And 12 GB Ram ????

Hi Guys I need some help

http://rapidshare.com/files/418884529/Core_i7_920_oc_4G_2008.12.12__ENG_.pdf ---> Is This Guide using good voltages ???

I used that guide Gigabyte UD5 to overclock the machine at 4GHZ
seems to be stable but as soon as i try to change my ram 8-8-8-24
to 1600 i cannot boot.

Any ideas or what is the best way to OC the i7 920 at 4 or 4.2 ??

I have a i7 920 D0 and i am using the H50 Corsair Cooler And Corsair Memory

Thanks for your help

Probably needs more VTT/QPI voltage...

Instead of trial and error OCing....you should consider a more methodical approach as outlined in my guide (linked in my sig). Take a little time and do it right

Hi pal thanks for your reply

I already read your guide ...
but its kind of confusing especially because
english its not my first language

i get lost here ....

" First overclock!
Go back into the BIOS and set the CPU Clock Ratio, the Uncore Clock Ratio, and the System Memory Multiplier (SPD). "

Anyway do you have anything more simple to understand ?

Thanks in advance for your help

Sorry, in the previous section I explained HOW to adjust those setting....but the part that's confusing you is where I'm telling the readers NOW perform the changes...

Does that make it more clear?

.............................................

Back to your question...what is the memory set to before you attempt the changes to DDR3-1600 8-8-8 ?

I followed that Guide step by step and it gives me a 4.0 stable
but i think the voltages are kind of high.......

The memory multiplayer was x6 and 8-8-8-20 I think The default..... one


I am reading your guide and trying to understand better
thanks again for taking your time and sharing your knowledge with all of us.

How fast were you able to run the memory in step #2 ?

I couldnt reach the step 2
While trying to " LOCK IN YOUR DESIRED QPI CLOCK RADIO"
i dont have x16,x18,x20 my QPI Clock i think starts in x36
anyway i used x36 and run the tests whit no problem no error
here are some pictures....

I think Gigabyte Has a Remote Overclocking Program
Cloud Overclock maybe i can setup that and you can give me a hand
if its that ok with you .....

Thanks in advance.

Right now i am using this setup since the machine is kind of similar but its no stable under the stress test maybe because i have 12 GB RAM.....

What do you think i have to tweek to make it stable and reach at least 4.0Ghz ???????





Thanks !!!!!

Change the timings back to 8-8-8-24-2T at DDR3-1600 (assuming these are the SPD timings at rated frequency; consider tightening timings after achieving a stable clock), DRAM voltage to 1.65V (again assuming this is the rated Vddq at 800MHz), CPU Vcore to 1.3-1.35V, CPU PLL to 1.80V, QPI/VTT Voltage to 1.40-1.45V, and PCI Express Frequency (MHz) to 104.

Found this template and i am using it right now... but i cant manage to make it stable

Tried with different QPI here are the results

1260 = Computer Restart No Blue Screen
1280 = Blue Screen Error 124
1300 = Blue Screen Error 124
1320 = Blue Screen Error 124
1340 = Computer Restarted No Blue Screen
1360 = Computer Restarted No Blue Screen
1380 = Windows Freezes In Logo

All of the these results are 2 o 3 seconds after running prime95.

If i changed the DRAM to 1.6 and sometimes i got Blue screens
with errors:

-0003B
-000D1
-000FC
-0001E

All with different QPI Values......

Do you have any advice to make my machine stable ?

By the way the memory its a Corsair 8-8-8-24 1.66v

Thanks in advance.

Bump Vcore, QPI/VTT Voltage, and PCI Express Frequency (MHz) to those values I suggested. And the settings in your last posted template are for 4.2GHz. Curious as to why you're attempting a 4.2GHz clock when you never got 4.0GHz stable?
