Hello;

My specs are as follows:

MOBO /// Asus SABERTOOTH 990FX/GEN3 R2.0
MEM /// Corsair Dominator, 16GB Dual/Quad Channel DDR3 (4x4Gb) (CMP16GX3M4X1600C7)
CPU /// AMD FX 8350 4.0/4.2Ghz

Here they state: http://www.amd.com/en-us/products/processors/desktop/fx (UNDER FEATURES TAB)
"Supports up to DDR3-1866"

Then in these columns they say: http://support.amd.com/en-us/kb-articles/Pages/ddr3memoryfrequencyguide.aspx
--> halfway the page, in the column you can derive my memory will run at 1333Mhz when using 4 memory sticks in DUAL RANK MEMORY mode, and it'll run at 1600Mhz when using 4 sticks in SINGLE RANK MEMORY mode.

Can someone elaborate for me? My memory is designed to run at 1600Mhz. Right now it's running at 1333Mhz, if I crank it in BIOS my computer simply crashes when going into windows.

DUAL RANK? SINGLE RANK?... Does this mean dual channel? single channel? if so what's my best option here.

I do 3D Visual Design and I need memory speed, but at what cost? What's the difference between single/dual rank? How do I enable single ranking?

regards

For mainstream memory, "ranks" are basically sides: each side of a typical desktop DIMM has 8 chips, each one 8-bits wide for a total of 64 data bits. A single-rank DIMM has chips only on one side while a dual-rank DIMM has chips on both.

For server DIMMs, registered modules can have up to eight ranks per DIMM, which means up to four rows of eight ICs on each side; 64 chips total not counting the register chips themselves.

ok so basicly i'm still stuck at 1333Mhz with this corsair memory, even on a Asus SABERTOOTH 990FX/GEN3 R2.0 because the memory controller in the AMD cpu simply sucks... :(
