hello, i just purchased a new system:
mobo: GA-EP45-DS4
CPU: Q9450
GPU: 9800GXT black edition
RAM: OCZ 4096MB, DDRII800, Kit Of 2, CL 4-4-4-15, Titanium (OCZ2T800C44GK)
PSU: OCZ 600w StealthXStream
well, i was trying to install a new OS. started with XP 32bit, it freezed (system running, but screen shows everything stopped..) at install when showing 34 minutes left..
when trying to install Vista 64bit, it freezed randomly.
I've searched all over the internet, but haven't really found a solution for my problem.. is it mainboard/RAM incompatibility? Should i buy a new RAM?
It is probably bad ram, it is more unusual for a mobo to be bad.
Run memtest with each stick in the first slot, then the second slot...etc. You are trying to find out if it is the mobo, or the ram.
However, since no ram seems to work, either the mobo is bad, and needs replacing, or the ram is not compatible.
The OCZ ram configurator does not seem to have been updated much, and does not have your mobo on it.
Corsair, Kingston, and Patriot have configurators, so you could check there to see what they have for supported ram.
What to do now?
If you can't identify which is bad, I think I would replace the ram with modules that the Corsair configurator suggests. Don't look for modules with low timings, since they will need higher voltage adjustments to run at that level. You want ram that runs out of the box at default SPD levels on your mobo.

Let me understand your configuration before we go chasing fixes. Are you running the cpu, memory, and mch settings at stock? The only reasonable non-stock item would be memory voltage. If the problem persists at stock then hardware problems are a good bet.
yea, everything is at stock (default mainboard settings) except memory - 2.1V (1.8 default) and 4,4,4,15 (5,5,5,18), i tried to change these values.. leave it unchanged etc.
I will return PC to reseller, so they will test it and install OS on it. I am trying to get this PC to work for 3 days, and i am really tired of this.
