This is a LGA1366 CPU, the use of ram depends on which kind of motherboard you are running right now -
1. Server board, no matter one-way or 2-way (two piece of E5507 running on the board, it could run with either ECC or ECC+Reg DDR-3 ram max support upto DDR3-1333.
2. Normal desktop X58 motherboard, could only use normal DDR3-1333 (unbuffered) or ECC ram.
No matter which of the above you are using, it can support 1333Mhz, just make sure which type of ram you are using right now, the model number marked on ram would show which type of ram you are using cause you can't mix it up, for example -
PC3-6400U (end with U = DESKTOP RAM)
PC3-6400E (end with E = ECC RAM)
PC3-6400R (end with R = ECC+REG)
PC3-8500 = DDR3-1066
PC3-10600 = DDR3-1333
PC3-12800 = DDR3-1600
the worst could be only run on 800Mhz restricted by the CPU ram controller.
I experienced X5560 use on X58 cound only run maximum on 1333Mhz even I plug on DDR3-1600 & DDR3-1866 ram but it's workable, and in the offical website of Intel it also show maximum support DDR3-1333.
