I recently picked up the Leadtek board which uses the Sis 735 chip(set) This chipset allows 1/5 and 1/6 pci/agp dividers which should allow extremely high FBS overclocking without overclocking the PCI/AGP bus.
After a paticulary frustrating setup where both a TV tuner card and an IDE RAID controller card simply would not work with the board and the included "Speed Gear" FBS overclocking utility won't install to W2K/XP, I was able to see how this board overclocks using the limited FBS available in the BIOS. Using an unlocked AXIA 1.2GHz and some decent Nayna? -7 2t memory the motherboard croaks somewhere between 138 and 144MHz FBS. By croaking, I mean no post and a dying bleeping noise from the pc speaker. Strangly enough, one can run the fastest memory settings at 138/138 but even the slowest settings won't allow posting at the next step up which is 144MHz. So much for using those 1/5 or 1/6 dividers. Speaking of memory settings, there's lots of arcane options that I'm sure some engineers would not understand the ramifications of, they are not explaned in the manual and should have been linked by a slow, med, fast switch in my opinion. The designers must not of had access to W2K or XP because the boards BIOS does not properly support those OS's ACPI which means resource problems if you install the OS in the (default) ACPI mode. I haven't tried the board with Win98. There might be less problems with add on devices/drivers and the Speed Gear would allow more control with overclocking.
Leadtek needs to stick to copying Nvidia reference video cards and leave motherboard design and production to the big boys.
Just my 2c - M.
