Memory Speed advise

[duoofdeath1]

Hello All,

Currently i have an ASUS A55BM-E motherboard, AMD A10-7700K CPU, and a XFX Radeon HD 6790. I don't have any memory picked out yet but understand that the mobo can handle up to 2400MHz (also understand I can install higher but it will be clocked down) but I read somewhere the CPU will only handle 2133MHz. So my question is, do i get 2133MHz or 2400MHz? Primarily looking to keep this cheap so looking at 8GB kits unless i can get a steal on a 16GB.

EDIT: or do i just say screw over-thinking it and get 1600MHz since that is what most of the people over on pcpartpicker.com seem to be using with this cpu?

EDIT EDIT: I think I am probably going to go with this kit unless somebody thinks it won't work or won't run at the 2400MHz.

Thanks for any and all insight

I'd go the 2133, the faster data rate will be very good for the iGPU, as well as regular system use

Actually i got a hold of G.Skill tech support and they recommended i get this kit because of the speed and lower cas latency.

He said "It requires advanced overclocking experience to reach DDR3-1866+, so a low latency DDR3-1866 may be best. "
