AMD's CPUs have the same natively-supported DDR3 speeds.
i have overlooked going into this much depth in the past and due to it i am stuck with many annoyances on my current system.
i was unaware that amd was using an on-chip memory controller i thought it was on the mobo. but either way the only board out there with any pci-e 3.0 slots is the generation 3 sabertooth v2.0 which has yet to released to general public. which is why my statement of amd being behind the curve is fact not only in performance but with the proper abilities to run pci-e 3.0 vid-cards i am unsure if the new vishera bulldozers are built off pci-e revision 3.0 but whether they are or aren't being that there are no boards on the market readily available to amd with 3.0 ... All signs point clearly to make your new build Intel
please don't get me wrong i was not knocking intel in any way when i said i question the processor because it's memory controller stops native support after 1600. if i knew the amd's did the same when i was building my current machine i would have been asking the amd people all sorts of questions too
in retrospect if i had known that amd's do the same thing i probably wouldn't have bothered to ask any questions because i know i can run higher ram on my amd...without hurting the cpu although the system does become a bit unstable cus i'm not using certified for board mem
