[SOLVED] Wrong memory speeds

[sugarskull]

Hello!
I got corsair vengeance ddr3 (2x4gb) 1600mhz memory kit (MOBO: Asrock 970 pro3 & CPU: AMD fx-6300). In bios it shows possible frequencies but there is no 1600mhz, only 880, 1172, 1466, 1760, 2052, 2346, 2640. Which one should I pick or how do I get correct speeds appear in bios. Sticks are in A1 and B1 slots as recommended in the manual.

I chose 1760mhz in bios as it's closets to the 1600mhz. In CPU-Z it shows 880mhz for my RAM frequency and in Windows 800mhz.

those numbers are wonky.
I would go with the closest to the actual speed.
those numbers are not listed on the product page, it may be a glitch in the BIOS programming.

each step in the memory freqs you listed from the BIOS jump in irregular increments, first 80 above normal, then 106 above normal, then 133Mhz above normal versus the actual listed speeds which are all evenly grouped, each jumping by 266Mhz with the oddball 1800, but evenly distributed.
