Hi
my Soyo 025K2 seems only to run stable on nearly the slowest RAM settings.
I have 60ns FPM 72 pin memory and 256KB of 15ns cache (with ASTER TAG RAM). I've already tried other memory modules (60ns and 70ns), all of them only work reliably with the attached settings.
Any idea? Maybe an outdated, unstable BIOS? cheap memory (TI and SEC).
Speedsys results:
Memory Bandwith: 24.51MB/s
Data cache L1 (16KB) 55.83 MB/s
Data cache L2 (256KB) 30.56 MB/s
Memory throughput 17.40 MB/s
with faster settings the system isn't stable but I get the following results:
Memory Bandwith: 37.31MB/s
Data cache L1 (16KB) 73.54 MB/s
Data cache L2 (256KB) 50.81 MB/s
Memory throughput 30.91 MB/s
there is no faster stable setting than the one with the slow results (tried every setting).
when the system gets unstable it hangs eg when loading himem or it is booting from disk instead from floppy (lolled at that) or it hangs after pnp initialization of the SB16 ISA card. sometimes it finishes booting and i can start "edit.com" which then stays black with white text and freezes. if i try to start win 3.11 the splash screen shows up and then it crashes to dos.
it seems that this behaviour starts when I install the winbond VLB I/O controller. when I use a pure ISA I/O controller instead, the system is stable at the second-fastest memory settings.
