Hey, I am hoping to get an answer to my question. I have recently tried upgrading my RAM on my PC. I was running 8GB of DDR3 1066 before the attempted upgrade with no issues. The first RAM I installed to upgrade was 16GB (2 x 8GB) of DDR3 1600. The RAM would not let the computer boot up, not even into the bios. I tried booting with just one stick of 8GB of the same RAM which would result in the bios loading up, but once Windows 7 tried to load it would go immediately to a BSOD. Another interesting issue I found is that when I did run the 1 stick of 8GB DDR3 1600, if you looked into the BIOS at the speed of the RAM it was only reading DDR3-1333. Settings were set to automatic on all options and even if I tried to manually change the memory speed my highest option was DDR3-1333. Next thinking that the RAM was possibly faulty or there was some kind of incompatibility, I went down to 8GB (2 x 4GB) of DDR3 1333. This produced the exact same result regardless if I installed the RAM by itself or with my old RAM on the other two DIMM slots. In the specifications of my motherboard I have seen that it is supposed to support DDR3 2600+(OC)/2133(OC)/1866(OC)/1600/1333/1066 types of RAM. I will list my specs below for further information. I am under the assumption that the speeds of the RAM do not have to match as I was told by the store tech which I purchased the RAM from. The BIOS should adjust the higher speed RAM to match that of the other lower speed RAM am I correct? Any help is appreciated.
