155/84/46 for 2-1-1-1, and I assume that "DRAM Faster" = 1ws/0ws?
I get 155/76/56 for 3-1-1-1 and DRAM 0ws/0ws. Data on page 4 of this thread.
Did your system pass HIMEM with these settings? Will you be able to install Windows and run a game? It is fairly easy to get faster settings going in DOS.
Are you also using 12 ns for the TAG?
I might have some real 12 ns cache coming. At which time, I intend to try 10 ns fake, 12 ns fake, and 12 ns real with IBM 5x86c, Am5x86-150.
Have you tried 512K or 1024K double-banked? How much RAM are you using? Might want to try a single stick of 32 MB. I have a single stick of 50 ns FPM, 32 MB, but it hasn't made any difference over my 60 ns sticks.
AP43 contains a SiS 496, which has a slight memory read edge on the UMC UM8881 for the lowest wait state.
