Std Speed,
Question is why did the gits who sold me the kit in the first place use the slower memory? Cost I supose
Personally I would never build a machine with underclocked RAM. I would go back to the place you bought it and show them that they sold you a machine with the wrong RAM (not the proper RAM for the speed anyway) and see if they will swap it out for PC-3200. It cannot hurt to try.
Take Care,
Richard
