*Due to AMD CPU limitation, DDR2 1066 is supported by AM2+ CPU for one DIMM per channel only.

Ive got a 7750 and Ive got 8g ram, 4x2g. It says 1066mhz but it wont work. whay is that?
ANSWER - The AM2+ can ONLY handle 1066 if one bank of memory is used. .
If both banks are used then 1066 will not work. It will show and work as 800mhz. IF that person took the 2nd dimm bank out, then the one remaining pair would function as 1066.
Does that make any sense?? lol. im bad at this.

On the post screen it now said 1066 Ganged. I have mine set to ganged because I read somewhere that the quad core will handle 8 GB better in 8 single channel modes rather than 4 dual channels.
