I'm thinking about buying this CPU
AMD Phenom II X2 555 Black Edition Callisto 3.2GHz 2 x 512KB L2 Cache 6MB L3 Cache Socket AM3 80W Dual-Core Desktop Processor - C3 Revision HDZ555WFGMBOX
And this Mobo
MSI 890FXA-GD70 AM3 AMD 890FX SATA 6Gb/s USB 3.0 ATX AMD
And this RAM
OCZ Flex EX 8GB (2 x 4GB) 240-Pin DDR3 SDRAM DDR3 2133 (PC3 17000)
My first concern is the RAM, will it be compatible with my Mobo/CPU? I've heard that 2133 RAM is only compatible with the i7 CPU's and that it's not compatible with AMD?
Secondly, I would appreciate any assistance, guidance, or links as to help explain how to unlock this particular CPU into a Quad.
Thank you for taking the time to read and reply : o)
