Hi! I have a M4A79XTD EVO motherboard, a AMD Phenom II X4 945 CPU, and I'm running Windows 7 64bit.
I've been using G.Skill Ripjaws memory sticks for 5 years (2x 2GB): DDR3-1600 PC3-12800 CL 9-9-9-24 1.5v. And of my DIMM slots, I've had them sitting in DIMM_A1 and DIMM_B1 (My slots go A2, B2, A1, B1, and only now have I learned you should put both in matching slots, but with just 2 sticks I haven't had to).
I decided I should get 4GB more Ram, and ordered the exact same sticks I already had. And plopped them right into DIMM A2 and B2, only to see all my start up programs crash instantly on boot up, and no web browsers would function. If I'm lucky I can navigate through my folders before hitting a BSOD.
When I check the bios it tells me I have 8GB usable memory. And when I check in my Control panel > System and Security > System.. It actually says I have 12GB, but 8 usable. I tinkered around in the bios a bit but nothing fixed the issue. I took my 2 old sticks of RAM out, and put the 2 new sticks in DIMM B1 and A1, and my computer worked just fine, like it did before I bought the RAM. I've run memtest86+ on each individual stick, and they all seem to be working.
Then, when I used the program CPU-Z, I checked my memory slots and did notice a slight difference between the old and new sticks:
The Timings Table between the new and old pair are different. So I put the old sticks in DIMM B1/B2 and new in A1/A2. It helped a bit, my computer doesn't instantly start crashing programs. But it's still unstable. Browsers such as Chrome are very quick to crash. Games are crashing after moments of running, and I will still get BSOD, but less frequently.
Curiously, right now as I type this, 3 of my 4 sticks are in. 2 of the new, 1 of the old, in DIMM_A2/B2/B1. When I use 6GB it works fine, regardless of the sticks of RAM I use, or which DIMM slots they're in, as long as the matching RAM are in matching DIMMS (so the single old stick can be in A2 or A1).
In MSCONFIG's boot tab / Advanced options, Maximum memory is unchecked. My bios are up to date and currently in their default settings, and I have no idea what to do. Any help would be greatly appreciated!
