Hi - first off I like to say this site has a great community.. learned alot here..

So recently I purchased the Asus sabertooth 990fx R2.0 and fx8350.

I am using previous parts from my previous pc:

RAM - 8GB Crucial 1333 and 4GB from my old ASUS CM1630 (4 sticks all together)
PSU - 700w
GPU - 7870
Hard drives - One is actually an IDE with an adpater to make it SATA.

When I first ran the PC, the memory light on the board stayed lit, I hit the MemOK! button to get it to work..

In the bios it only recognized 4GB of Ram, maybe 2GB, i cannot remember.. anyway i fiddled around and set some things to auto (thats it) and now its seeing all my RAM..

I go to install WIN7 and i get some error code, i google it, and users advise to try using only one stick of ram for the install..

So i remove ram and only use 1 stick of the crucial and what do you know.. win7 is installed.. So I add back all the RAM, BIOS sees it.

So i boot up and get BSOD, reboot, BSOD, etc..

I cleared the CMOS. still seeing BSOD

finally i remove the 4GB of the old CM1630 RAM and im up and running.. installed apps, played some COD, maxed it out, temps are good.. went to bed.. then i see this morning the uptime is 2hrs...

Now Im looking at buy RAM thats specifically on ASUS QVL.. is this board really that sensitive to memory that I should get exactly whats on the QVL? Anything else I can do to rule out memory issues?? It all just seems to point to memory at this point.. Im not overclocking or anything..


Also, in the bios.. its not seeing my primary HDD with win7 installed.. but it boots win7 just fine.


Thank in advance.
 
Solution
It would be jumping the GUN, start by running memtest on your current ram http://memtest.org/ then decide based on that. I was not surprised with issues and mixed two kits but one of them should work fine.

Yes, I did reset the CMOS with the 8GB kit.. I do not know if it BSOD when i went sleep.. but the uptime this AM def. tells me it rebooted.. im currently at work now.. when i left home the cpu was idling at 35C w/ an uptime of 2hrs..

I will def. be monitoring when i get home, check the uptime, etc.. Just wondering if ordering RAM on the QVL right now is jumping the gun.. ? Everything just points to memory right now.. had to hit MemOK! to get into bios from the beginning.. then the win7 install with only one stick, now semi stable with the 8GB kit (in the beige slots btw), i should have checked if WIN7 did a WIN UPDATE to see if it installed something and rebooted when i was sleeping.

The board is not that sensitive to memory, however if you have 4 sticks of RAM and they don't work when all of them are in, but do when only certain sticks are being used, that leads me to believe that those sticks just aren't playing nice with each other on that board. If you really want to guarantee that any RAM you get will work, then yes the QVL is the place for that. I have basically the same board (the GEN3 version) and I am running RAM that isn't on the QVL, and I have even overclocked it, and it will pass memtest for hours.

On a second note, have you tried running memtest on each stick individually?

no reboot for 10hrs.. added another stick. stable for 1h34m.. been playing cod for about 40m as well.. will continue to monitor.. if this is stable, im good with 10GB of RAM.. I dont wanna see that bsod on my pc anymore....

now i gotta deal with this win7 license issue.. they think my copy is counterfiet.. have the disc right here.
