Huge amount of BSOD need help please!! Using WinDbg debugging tools.

Good information.

There are two BIOS updates listed at Asus P5Q3 Deluxe.
Both mention - 'Enhance the compatibility with certain memory'.
If your comfortable with updating the BIOS, upgrade to 2105.

Manually set your DRAM frequency to 666MHz.
Manually set your first four RAM timings to 7-7-7-20, leave the rest on 'Auto'.
You can leave the "Command Rate' at 2T.

Leave the DRAM and NB voltages where they are for now.

Test with memtest86+ for a full 7 passes, best to run overnight.
If memtest86+ passes then run Prime95 torture test.
CPU - Stress Test with Prime95
First open Real Temp to monitor CPU temperatures, don't go over 77.4°C.
Open Prime95 and stop the test if it is running, in Advanced tab select 'Round off checking', in the Options tab select 'Torture Test...', in the window that opens select 'Blend', after 'Number of torture test threads to run' enter 2, then click OK to start the test.
For checking CPU/RAM stability 2 hours should be adequate.

Intel® Core™2 Duo Processor E8500

Let us know the results.

That's good news, got to keep the dust cleaned up.

Do you have the stock Intel CPU cooler?

In RealTemp, click the settings button, then select the ATI box under 'other settings'.
Tell us the GPU temps.

Also let us know the memtest86+ test results.

That is definitely RAM issues.
When you're OC'ing, you adjust your settings, test for stability.
If it's not stable then you need to adjust settings, if still not stable, you need to return everything to stock settings and start over.

Let's try a couple setting adjustments before returning everything to stock settings.

Are the RAM settings still at:

Manually set your DRAM frequency to 666MHz.
Manually set your first four RAM timings to 7-7-7-20, leave the rest on 'Auto'.
You can leave the "Command Rate' at 2T.

Are your DRAM and NB voltages still at:

DRAM voltages: 1.80V
North bridge voltages: 1.26V

Your CPUZ SPD tab says DRAM should be 1.50v, so 1.80v should be more than enough.
Bump the NB voltage to 1.350v.

Run memtest86+ again.

Your welcome.

RAM can be very fickle and is known to throw intermittent errors, which are very hard to trace.

Let us know the results.

The memtest stopped after 5hours showing 6pass errors: 1101056 "unexpected interrupt - halting".
Wonder if its both RAM thats defected or just one of them, is it true that OCZ have lifetime warranty on theirs RAM? Cuz I remember when buying the RAM, on the package it says something like "lifetime warranty"(but yah can't find the receipt).
Last question do you recommend to use RAM that's by different brand at the same time? example 1 slot with OCZ RAM and the other one maybe from Kingston.
Gonna send my current one to OCZ for RMA, is these RAM compatible with my current one? if yes which one of them do you recommend? http://www.webhallen.com/sok/?title=...h_box_select=0
(my current one OCZ DDR3 PC3-12800 4gb(2x2gb) Plat ENHANCED BANDWIDTH)
Once again thank you alot for your help! All the instructions were really clearly and easy to follow! ^^

You're welcome.

Time to RMA the RAM.
The receipt should not be necessary, just contact them.

It is always best to get RAM from the same manufacturer and with the same frequency and timings, the same RAM kit is preferable.

This is your compatible RAM link.
P5Q3 Deluxe/WiFi-AP @n Memory/Device Support

It's best to get RAM that is listed on that site.

I would stay away from OCZ RAM as they have stopped making/selling it.

There are many others to choose from.
I've always had good luck with Corsair.
