I have an AZZA PT-5IT socket 7 motherboard (not a super7). It has 512 KB pipeline burst write-back cache that can accept 256 MB SDRAM (DIMM) or 256 MB EDO RAM (SIMM). Of course, it can only cache up to 64 MB as there is no write-through option in the BIOS.
It uses the Intel 430TX chipset and has options for 50, 60, 66, 75 Mhz FSB and 1.5, 2.0, 2.5, 3.0, 3.5, and 4.0 multipliers. It supports a wide range of voltages, 2.1, 2.5, 2.8, 2.9, 3.2, 3.3, 3.5 V.
The two questions I have are,
1) Are there hidden FSB settings besides what I postd above? There are 4 other possible combinations for jumpers. An ~83 Mhz setting would be ideal.
2) The motherboard seems to work with both the K6-266 @ 266 Mhz and Cyrix MII-400GP @ 263 Mhz. Which of these two cpus is considered the best all around performer? The reason for questioni 1) is to try to get the Cyrix MII-400GP to run at its rated frequency of 285 Mhz. I attempted the 75 Mhz w/4x but the BIOS reported 66 Mhz and didn't POST.
3) Are there any architectural differences between the Cyrix MII-400GP and the Cyrix 6x86MX-266/or MII-266 that the BIOS might need to know about for optimal performance?
