Hi, i have 2X1GB crucial ballistix tracer DDR2-8500 1066MHz...byt my problem is that when i see the speed in the BIOS the speed is to 800MHz and i can't up...CPU-Z show me that they are PC2-6400 800MHz....

My board is a K9A2 Platinum and the processor is Athlon 64 X2 6400+ 3.2GHz

Set the timings and voltage manually when overclocking your RAM. The motherboard can only detect JEDEC SPD timings and the fastest table is 800 MHz.
