Windows 7
Slight RAM problem,

When I built my computer I originaly had 2x2gb of Corsair XMS3 DDR3 1600 RAM in my P7P55D Deluxe motherboard. Recently I decided that I desired to upgrade from 4gb to 8gb and purchased the exact same RAM again. When I got the new sticks I noticed that the version was different from the original ones I purchased and its serial number was also different. The latest pair I got are CMX4GX3M2A1600C8 and v2.5 while the older pair are CMX4GX3M2A1600C9 v8.5. The timings are also different if I recall.

I isntalled the RAM anyways and thats where some small issues began to appear. For isntance upon booting my computer the computer will state "Detecting drives please wait..." this lasts for at least 3-5 minutes then states "No Drives found" then proceeds to boot to Windows. All my programs operate as usual (although Shogun 2: Total War has been crashing mysteriously) and I don't encounter the issue again until I reboot my computer.

My question would be, is this caused by the RAM being the same but just different versions of each other? Or does the motherboard just not like having 8gbs of RAM? The memory is registered on My Computer as 8gb.

PS: I also had a BSOD the today while Alt-Tab'ing Civilization 5 and the error message was "Memory_Management".

Any aid regarding my issue would be appreciated.
