I have an Asus M4A78T-E Motherboard

http://usa.asus.com/Motherboards/AMD_AM3/M4A78TE/#specifications

I'm currently running 4 GB of memory DDR3 PC8500 memory at 1333Mhz

http://www.newegg.com/Product/Produc...82E16820227346

I want to stick in another 8 GB, and I noticed that the DDR3 - 1333 memory is PC 10666,

For example:

http://www.microcenter.com/single_pr...uct_id=0364399

I'm trying to understand if there are any compatbility issues. The latency on the newer ram seems a little higher. The voltage matches at 1.5v.

Any issues?

Thanks,

The first one is PC3 8500 and it is at 1066 MT/s, no 1333. Generally there won't be any problems with mixing different speed modules, but personally I prefer to install the same type of RAM to my machine.
