Hi guys
Today i bought a new computer. The spec is
Athlon 2 X4 630
Biostar TA785G3-HD
Coolermaster 600w
Zion 2GB DDR3 1333

I installed amd's Toverclocker and its showing my RAM's maximum bandwidth as 686MHz. Is this normal or should i be getting 1333MHz?
Sorry if what i said is stupid. I really am new in this. I haven't overclocked this system.

I have attached the screenshot of Toverclocker..

The term DDR means Dual Data Rate.So your max is 686 X 2 = 1372.Hope this clears your doubt.

If you have a single module of 2GB, the speed is fine. for the RAM to work at 1333Mhz, you'll need to plug in 2 modules of exactly same specifications.

I dont think so.single or double module, the ram will work in 1333Mhz.But its shown as half the frequency as its DDR ram.Dual Data Rate.

I doubt the memory controller will see the dual channel architecture with 1x stick.
