Hello, 

In the bios it says 1333MHz. In CPU-Z it says 686. I have an FX 4100 @ 3.6GHz, my mobo is M5A97 Evo. 

I can't find anywhere at all about where it says how much RAM is supported, etc for either of the products as the websites are crap. I changed the RAM freq. in the BIOS settings to 1866, then I got a blue screen. 

I am stupid. Please help

JamieWright19: I have no idea what that means.


Double Data Rate... i.e. the DDR part of what is probably DDR2-1866, refers to the clock rate being doubled from the base rate. 
I'm not sure I have the appropriate knowledge to explain it correctly, that's where Wikipedia comes in. :)

Ultimately, it will actually be running at the full 1866MHz, but CPU-Z will report half, because that's what it is seeing.

Although, it's probably more like DDR3, considering the rated speed is 1866MHz, yet it's reporting 686MHz. Still, the same principle applies.
