My supply of EDO/FPM is limited and I would prefer to use the faster SDRAM but this motherboard will not recognize more than 32MB. I have tested several 64MB and 128MB modules on multiple BIOS releases: the original, Rom.by patched (from this thread) and Unicore 2.2 (from RetroWeb).

Is the 64 recognized as 16 and the 128 as 32? You may have this issue:
