sorry if this is a old question.
im thinking of upgrading my mobo from am2+ to am3
all the mobos are only suporting PC3-10600
But can you put in a PC3-12800 and do some FSB clocking and ram timing to set it to its original 1600mhz
Yep, you can use 1600 MHz RAM, it depends upon your CPU. The 4/6-core AMD CPUs will support the DDR3-1600 MHz. Use the AI OC Tuner -> DOCP and DRAM OC Profile to set the 1600 MHz. See 3-11~3-12 in the manual.
The difference between 1600 vs 2000 MHz RAM is not that much 1~2% assuming low CAS RAM, 1333 CAS 8 can perform same or better than many 1600 CAS 9. Also toy want tight CAS timings e.g. 1333 8-8-8, 1600 8-8-8/9-9-9, 1866 9-9-9, 2000 9-9-9.
thx so much m8 for the help well the cost for 2000mhz is only 20% to the 1600mhz so cost wise it dosent mather.
im running a AMD Quad 965 at 3,9ghz atm so im gonna upgrade my ram and my mobo, some problems has fallen ower my old asus, but it is 2 years old so its nice enought. yeah im gonna get some nice 1600mhz
