[Request] Amptron M930LMR memory speed

[Repo Man]

Hello. This old P4 motherboard is a solid performer as is for what I'm using it for, but this would be nice if possible. It officially only supports 400 MHz FSB CPUs, but it will work with 533 ones. When you run a 400 MHz FSB CPU, you can set the memory for 166 MHz (100/166) but when you run a 533 it only allows you to use 133/133, which narrows the performance improvement of the 533 bus CPU over the 400 one. I tried the BIOS for the P4S5A, which is a nearly identical motherboard and the board will work with it and allow you to set the FSB/memory to 133/166, but there is a hardware difference which prevents it from recognizing the CPU; on every power up, you have to enter CMOS and manually set the multiplier and FSB.

I tried using AMIBCP, but I wasn't able to change this setting, so after that I'm out of my depth. Any help would be greatly appreciated.

Here is the P4S5A BIOS.
