My guess is that this program doesn't know how to measure RAM speed in actual Megabytes/second. The relative measure against other systems may have some validity, if the program was clever enough to make its test independent of the speed the RAM's running out of. Disable Fast RAM and see if the chip numbers come up the same. >Instr Cache is enabled, Burst mode >Data Cache is enabled, Write Allocation That's correct default setting. >--- Jim -- Dave Haynie Commodore-Amiga (Amiga 3000) "The Crew That Never Rests" {uunet|pyramid|rutgers}!cbmvax!daveh PLINK: hazy BIX: hazy "What works for me might work for you" -Jimmy Buffett
