Okay, new BSOD appeared. I was playing WoW for mayby 20min and second after clicking "Exit Game" computer crashed.
I will upload the dump file so you can check it too.
This time it was BAD_POOL_CALLER.

I will also start testing my RAM now.

Nothing new in the dump. We will wait for the Memtest results.

Zero errors after 7 passes.

I also included my RAM settings to this post, if needed.

EDIT: Decided to go with lower settings just to be sure, so its running 9-9-9-24 now.
Thats becouse i think these RAM are specced to that speed, not 8-8-8-20.
Row Cycle Time is at 32 now. I would like someone to confirm if these are right for this RAM.

Zero errors with memtest86+, that's good.
Unfortunately it doesn't mean there are no RAM issues, now run Prime95 as mentioned below.

Looser timings won't hurt anything.

Go to BIOS and check the DRAM voltage, post it here.
Should be at least 1.5v. If it is still 1.55v it's ok, just leave it there.

The SPD tab from CPUZ is the manufacturers recommended settings at different DRAM Frequencies.
Your previously posted SPD, JEDEC #2 for 533 MHz is 7-7-7-20 and command rate 2T.

You can leave them at 8-8-8-20 if your happy with that, you won't see any difference in performance from 7-7-7-20.
If you want to change for testing, enter the first four timings, 7-7-7-20, manually and leave the rest in auto.
Make sure the Command rate stays at 2T.
Leave it in DC Mode: Unganged.

Run Prime95 torture test, this will test CPU and RAM. For at least one hour.

CPU - Stress Test with Prime95

When you open Prime95 click 'Options' tab > Torture Test > select 'Blend', fill in number of threads to run.
Be sure to watch the CPU temps with Core Temp.
Stop the test if the temps get to 60 deg C.

Let us know the results.

I just started Prime95 Blend test, but i dont think this will fail.
I have ran Blend for over hour before and it CPU didnt even get over 50*C thanks to my Mugen 2.
But if it fails, i will report here.

EDIT: I left my RAM settings to 9-9-9-24 just to be sure that it isnt causing this. Also i raised voltage from 1.55 to 1.625 (a friend of mine suggested to raise it a little).
Also i noticed something when i loosened the timings. Usually when i login to WoW, my FPS is VERY low for mayby 5 second, but now it didnt do that. Im not sure if thats permanent change or i was just lucky, i will test that more when Prime has stopped running.

After over hour of Prime, no errors/crashes.

Temps: CPU: 48*C
MoBo: 27*C

Also, is it safe to have RAM voltage up to 1,5625?
Re-checked the voltages and it was 1,562 and not 1,625 ^^.

Good news that Prime95 passed.

The RAM voltage should be alright for your system.

When you posted the NB voltage was this from the CPU/NB Voltage?
If this is not what you posted, check it and post it here.
You might have to set it to Manual to get a voltage reading.

Since the tests all passed, try to re-create the last BSoD from your game.

Yes, it was from CPU/NB Offset Voltage and it was on [Auto], but next to it reads 1.150 on gray, so i think its on 1.150V.
I have played some time now without any errors or crashes. Hopefully it was becouse of too tight timings/low voltage.
If i get a crash, i will post it here.

More good news, I hope it's going to be stable for you from now on.

If you get another crash post here.

The next step with the RAM would be some voltage adjustments for RAM and CPU/NB.
You have to be very careful with CPU/NB voltage.

Let us know how it's going, if you have no crashes in the next week drop us a post.
