Just re-visititing this post...

In reviewing the data in spreadsheet format, it becomes obvious that the Main RAM Read Speeds are about the same...it is only the Write Speeds that are slower.

At 66MHz (15 nS) and with no caches enabled, the difference is 151 - 90 = 61 nS...or about 4 clocks.

What could introduce a 4 clock "delay" into the Write path only? BIOS wait states? Why would a mainboard designer want to do this?
