FSB to bandwidth on the DS4:



380FSB 5920/5931
390FSB 6071/6099
400FSB 6218/ 6249
410FSB
420FSB 6492/6519
430FSB
440FSB 6792/6825
450FSB
460FSB 7117/7133
470FSB
480FSB RAM goes weird... 43/43
490FSB
500FSB 353/354

The tests were ran using SiSoft SANDRA and RAM was 1:1 to FSB. Timings were nothing special, just to make sure I didnt run out of space or need to jack up the voltage.

BIOS is F5F.

Can someone in the know confirm or deny that the strap is based on the FSB: RAM Multiplier, not the FSB?
