Freezing After Installing RAM

post #1 of 2
Thread Starter 
The other day I installed 8 more GB DDR3 into my computer. I couldn't buy the same memory because NewEgg has dc'd the product, but I was careful (I thought) in trying to make sure they matched. Both are PC3 12800 and have the same frequency (666MHz). However since I installed, I have been getting random system lock-ups, not blue screens, but everything just freezes. I did some research and discovered that the new memory differed in 2 aspects, on one the CAS Latency is 9, on the other it's 11. Also, the voltage differs, on one it is 1.5v, 1.65 on the other.

My motherboard has dual channel memory, everything is unlocked and tunable. My question is there any way I can install these RAM units, or tune them so that they get along together? I have ruled out everything else (I think) to be the cause of these freezes, and I can't reproduce them, except that in that when I try to to run Asus auto-clock, which used to run fine, it freezes up. Other than that it is random freezes.

Any advice would be greatly appreciated.

Note- I have already figured out I may need to take out the new RAM, RMA it to NewEgg, and get a 16GB set that will surely be compatible. I am trying to figure if there is anything I can do besides that. Thanks in advance.

Voltage won't matter and they are at the same speed as I understand it. So, what you'll need to do it match the timings. See which one has the looser timings and input those in the Bios so the timings are the same for both RAM.
