Asrock 970 pro3 and 2133 memory?
Im thinking about getting a, asrock 970 PRO3 with AMD FX-6300 Vishera 3.5GHz (4.1GHz Turbo) G.SKILL Sniper Series 8GB (2 x 4GB) 240-Pin DDR3 SDRAM DDR3 2133 XFX Core Edition FX-785A-CNL4 Radeon HD 7850 2GB 256-bit GDDR5 PCI Express 3.0 x16 CORSAIR CX Series CX750 750W .. Question is What will i have to do in bios to make sure the ram and cpu will operate correctly, If anything at all . i know that the mobo supports 2100, but will i have to change any settings to accommodate the higher speed or will it work at right speed by default ?
AMD FX CPUs much like the current generation Intel CPUs do not benefit much at all from RAM faster than DDR3 1600. You can use it but it will gain you nothing at all in gaming and about 1-2% in things like video rendering. If the RAM s very close in price to DDR3 1600 then by all means go for it but don't spend extra money there. All you will need to do is go in BIOS and set the RAM to it's rated speed and timings.
A system with a single HD 7850 only needs a recommended 450w power supply. Even running 2 in Crossfire only needs 600 watts. I would get a better power supply or put the money saved there in a better graphics card. The CX series is good but it's Corsair's budget line and I would not trust it with a high end graphics card or multi GPU system. If you want to stick with a single HD 7850 just get the CX 500. The 7850 or 7870 are about the highest end cards I would run on a CX series.
