Amd tri channel true 2x16x crossfire 2133mhz memory

[darwahan]

please this is driving me nuts........

what is the fastest memory speed that amd cpus support?
(natively, not through overclock)

is there a motherboard that will run crossfire with both lanes at 16x?
(an amd motherboard, not an intel chipset board)

Is amd going to be implementing tri channel in their x6 cpu memory controlers?

1333Mhz

790FX. There will be an 890FX coming out fairly soon.

Not that I have heard.

890 chipset boards are already a reality and support 2133 according to the specs, but i thought the integrated memory controler only did 1600 max.

You asked what the fastest frequency the CPU supports....
From "AMD Phenom™ II Key Architectural Features" found here:
http://www.amd.com/us/products/desktop/processors/phenom-ii/Pages/phenom-ii-key-architectural-features.aspx

"Support for unregistered DIMMs up to PC2 8500(DDR2-1066MHz) and PC3 10600 (DDR3-1333MHz) – AM3"
Will it run memory at faster clocks? MAYBE, depending on the luck of the draw and such. All the board does is supply power. It's up to the integrated memory controller on the CPU to actually operate the DRAM.
Will you benefit from higher memory clocks? Not really.

You asked about x16. 890GX boards operate at x8/x8 speeds in crossfire. 890FX chipset will supply full bandwidth and are not out yet.
