CAS# latency, RAS# to CAS# and RAS# precharge is available on the bios, so i can change it by myself, but what about tRAS and tRC ?

It looks almost good, but your tRAS (the one with the typo in the BIOS... "RAS Precharge Dealy" biggrin.gif) should be set to 15 rather than 13.

So far I've done everything you said:
Changed the vcore to 1.29V, but in CPU-Z I can see no difference 0_o (Still 1.23V) ***?
Added more voltage to the RAM (2.0V)
FSB : DRAM = 1:1
Removed the generic memory stick
Changed RAM timings to 5-5-5-15

And so far I've got few blue screens, crashes in OCCT and a head ache..

You have more suggestions?

Setting the CPU voltage in BIOS to 1.29 is not the actual vcore usage by the cpu. This is the Vcore droop people talk about, this is ok. All this means is at load your cpu is using enough voltage.

I am guessing that your cpu is probably stable - to some extent - as you can load programs. Blue screens usually mean memory instability if it is consistent, as opposed to an unstable cpu core having a random fit.

Down load Memtest86+ and boot it using the USB boot drive method or a floppy (cd can work too) http://www.bootdisk.com/pendrive.htm

You need to check Memory voltage to make sure it is at the required setting, no higher no lower. So if it says 2.1 voltage needed place it at that. Also try increasing North Bridge voltage to 1.3.

Your other option is to place memory into AUTO, but check its frequency to make sure it is at default ie: 800 / 1066

EDIT::

This is your RAM? http://www.gskill.com/products.php?index=63 Voltage should be 1.8 (2.0 could damage it). I would just leave it in Auto and set the frequency to 800 and let the BIOS do the rest.

I already have memtest on a cd, when exactly I should check the memory? cuz w/o OC memory have no issues. -yeah that's my ram.


OK, I found the cd and run one test, (CPU @ 2.99Ghz which unstable) no errors at all:
http://i52.tinypic.com/15gyp74.jpg
So the ram is fine, and no blue screens so far (after I've set 5-5-5-15).
But the OCCT still crash.
north bridge is 1.29V
and the ram 1.8V


PRIME95 gives me this error:
Quote:
FATAL ERROR: Rounding was 0.5, expected less than 0.4
maybe it mean something valuable.
