It is not surprising you are having problems. Why didn't you do what is normally advised and stick to matching memory. Note also that the motherboard doesn't spec for the 1066 memory - "DDR3 2000(OC)/1800(OC)/1333 Support for up to 2000 MHz SLI-Ready Memory with EPP"
Cas Latency 8
Cas Latency 7
So I bought and build my new computer about a month ago and bought this DDR3 Memory for it:
I then recently bought this Memory to Add to it to have 4 GB of RAM:
When I went to add the Memory and turn the computer back on, but it would lock up on the memory test the BIOS does at boot. I rearange the Memory again thinking I had the wrong configuration, checked the Motherboard Manual and everything is in place correctly. A also used each set of memory indivitually and they work individually.
My only thought was that since they are different speeds and voltage they wouldnt work together. Should they work?
