M4A77TD PRO RAM OVER CLOCKING

post #1 of 4
Thread Starter 
I have a M4A77TD PRO Motherboard with an AMD Phenom II X4 965 black processor and 16GB Corsair Vengeance 1866oc memory.
I am trying to get the board to acknowledge the 1866 speed of the ram. the most I see in the bios is 1600. I am new to overclocking and would like to get my ram working at 1866. can any one help me with this. there are no other overclocks on my system at this time.

thank you

Phenom II processors do not have a memory multiplier available for native DDR3-1866, unfortunately.

In order to get there, you'll have to overclock the base clock (from 200Mhz to at least 233Mhz) and adjust your other multipliers (CPU multi, NB multi, etc) so that they run at the speeds you want (stock or whatever). Additional CPU-NB frequency overclocking will be needed to fully leverage the performance and augment stability.

 

An alternative to achieving similar bandwidth levels, if it concerns you, would be to lower your timings at DDR3-1600.

 

FX processors have native DDR3-1866 support.

Thank you very much

Alternatively, the memory could be kept at 1600, and the timings could be tightened, lowered.
