I have some Kingston HyperX PC8500 1066 4GB 2x2GB set of ram. I have got it post 1066 no problem and have tweaked the timings to get some pretty impressive results for some DDR2. But, its still showing up as PC6400 in Sandra and everything else. Doesnt this represent the bandwidth? How on earth do you unlock it? All my hardware I own says it supports PC8500 1066. I have read some GSKILL guys say theres post it as PC8500. Is this a Kingston thing?

CPU Type QuadCore AMD Phenom II X4 Black Edition 940, 3400 MHz (17 x 200)

It is likely that your RAM is DDR2 800 (PC6400), that can successfully be OCed to 1066 at the voltage and latencies recommended by Kingston. It sounds like Kingston didn't rename the profile on your sticks to show PC8500.

I'm having the exact same issue.. I recently purchased a Kingston HyperX pc2 8500 2 gig kit and both chips identify as pc2 6400.. and like yours these oc to 1066 no problem.. I was gonna complain to the company i bought the memory from but I didnt think it would be worth my time..

You don't need to complain as there's no such thing as DDR2-1066. As treefrog07 said, it's DDR2-800 that's sort of certified to work when overclocked. If they work at the advertised speed and required voltage, then there's nothing wrong.

Well I know that isnt a 100% correct.. Ive seen memory that identifies itself as pc2 8500.. in fact ive seen pc2 8900 as well a 533mhz and a 555mhz dual channel So I know there is such thing..

Because the correct profile was enabled in the BIOS. That still doesn't change the fact that DDR2-800 chips are used and you can verify that using CPU-Z.
