Hoss331 - i tried my ram on the divider below - so they ran at 931mhz or something with fsb at 458 - cpu@ 4.124ghz - this was fine - only thing was - my linx Gflops output was far less because my ram was like nearly 130mhz slower per stick.!! so i recon i'll loosen some timings to get them running at 1100mhz.
