Hello. I would like to have one overall retro motherboard for Pentium 4 socket 478 CPUs, and I was thinking about choosing i865PE chipset, mainly because of "masked" PAT, dualchannel, Sata, integrated USB 2.0.
I was thinking, that it will support Prescott CPUs as well, so I was expecting it will for sure take also all previous one, including Willamette.
But then, I've come accross this review of motherboard DFI Infitinity 865PE, where is mentioned, you can set FSB only from 200 to 400 (not, it is meant basic clock, so it means actualy 4x more FSB, so from 800 to 1600) So does it mean, I cannot set FSB to 533 or 400?

"Genie BIOS Setting screen is where users can adjust the Bus speed anywhere from 200MHz to 400MHz in 1MHz increments, although 400MHz seems rather unrealistic at this point."
I've remembered from long ago, on some other i865PE motherboard, that FSB range was from 100-300, so I was telling myself, it is ok, it will take 400, 533 and also 800 Mhz CPUs. But this seems, as it is not case on all motherboards with this chipset?
PS:
I've found the review of motherboard, that I've remembered it has 100-300 FSB. It was Abit IS7

"As it is, we have FSB manipulation from 100 - 300 FSB in 1MHz increments. We appreciate that you can manually key in whichever FSB you require. "
I wonder about downclocking mainly because, I want to take highest 800 Mhz FSB Pentium 4, and downclock it to 533 / 400 Mhz FSB version, so I don't have to have 3 CPUs for benchmarks, but only one.
