Hi ickymay, thanks again for your assistance.

I also noticed there was a new BIOS for my motherboard, I updated to the latest one Ver 3203 yesterday. I will keep watching, so far my system has been running for almost 48 hours without crashing / freezing. In the past I never went more than 3-4 days without a crash/freeze, so I will keep monitoring for a few more days and see what happens.

About my memory not being in the QVL, you are technically correct, although ASUS does list in the QVL the 8GB kit (2 x 4GB) version of the RAM I have, the 16GB kit I have is the exact same RAM but it has 4 sticks instead of just 2.

Is that still running with just a single stick ?

BTW we havent finished yet

No, I have been running with two sticks for almost 3 days now with no crashes/freezes.

so the new bios has maybe solved it ?

If it was me then my next step would be to download and install CPUID HW monitor

then downnload and run Prime95

then take a note of your voltages and temperatures for CPU and chipset at idle then run prime95 for 15 -20 minutes and see if if any of the cores generate errors ?

If they do plz post a screen shot of the error message here ?

I don't know for sure yet if the BIOS solved the issue, I am still not at the same RAM configuration I had when I had the last freeze, which was 4 sticks (16 GB of RAM). Today is going to be 5 days running with 2 sticks and so far no crashes / freezes.

Here is the sequence I have been following:

1. With previous BIOS (v 1101) and 4 RAM sticks (system froze after 3 days running).
2. With previous BIOS (v 1101) and 1 RAM stick, system ran for 6 days without freezing nor crashing, during this time I also let Prime 95 run for 24 hours with no errors reported.
3. With new BIOS (v 3203) and 2 RAM sticks, system has been running for almost 5 days now without freezing nor crashing, during this time I also ran Prime 95 for 24 hours with no errors reported.
4. Next step is going to be, to install all 4 RAM sticks now that I have the new BIOS (v 3203) and see what happens, I am also going to run Prime 95 for full 24 hours to see what happens.

And after I install all my RAM and if my system is still stable for a week or so, than I will continue adding back the rest of my hardware (GPU and hard drives) one at the time.

If your going to get errors with Prime95 its normally within the first ten minutes so 24 hours is rarely necessary or of any use unless your testing your cooling environment

make the jump to fitting all sticks of Ram and run Prime95 for twenty minutes and if no errors I would start putting components back in

Hi pichogve!

How's your system been doing since your last post?

I would be interested to know whether you solved the problem since I've got a very similar system (same CPU, same RAM, P8z68-deluxe motherboard, nVidia GPU) and apparently similar problems (BOSD, freeze), although I haven't thoroughly checked my minidump files yet.

My system is still having problems, I am at the point where I am thinking about buying new components (at least MB, video adapter and power supply).

The latest attempt I made to solve my problem was to change my RAM from DDR3 1600 to DDR3 1333 (still using all my 16 GB of RAM), and I also reconnected all my hardware components to my system (all the RAM and all my disk drives), after that my system was stable.

After running my system that way for about a week with no crashes I started reinstalling all my software and at one point I started seeing crashes again, so right now I have uninstalled all software I installed to find out which one is causing crashes. My next step is to start one piece of software at the time to find out which one is causing crashes.

So the common factor for producing crash/freeze is when you install 4 sticks of ram ?

If you can confirm this it would suggest that the Bios is not setting the correct timings and or voltages for the Ram when using four sticks ?

What happens is that with one stick of Ram can work perfectly then as you add another stick it alters the timing slightly and will produce an allowable error then with another stick timings change again and it will produce too many errors and you get a system freeze ?

If you can confirm its ok with one stick then freezes with 2 or more then you can sometimes get past this problem by manually bumping the voltage very slightly ?
