Since I'm having trouble finding any resellers stocking the Shuttle AK32E recommended earlier, another good option is the
MSI KT2 Combo-L (MS-6764) which seem to be in abundant supply. Newegg, among a few others, show them in stock. Same specs as the AK32E, largely.
My KT7 Raid hasn't died but I would like to dump it for a board with fewer issues. Is there a board with a different chipset (ie not a Via) that could put my SDRAM to use?
The aforementioned MSI board uses the very solid KT266A/VT8235 chipset. They don't come with fewer issues.
The problem here is RAID. I don't know of any XP-ready boards based on chipsets 'newer' than the KT133A that feature on-board RAID and SDRAM slots. So its either an older KT133A w/RAID, a newer KT266A without RAID (use add-in RAID card), or SIS735 without RAID (use add-in RAID card) like the ECS K7S5A Pro.
On a related note, I see that
ASRock has a whole line of Pentium4 400/533MHz boards based on i845, SIS645/651, and VIA P4X chipsets that feature both SDRAM + DDR-RAM slots. A few models are certified up to P4 3.06GHz and support HT.
As does ECS (almost assuredly the same boards used by ASRock):
P4VXASD2+ V5.X
P4IBASD V3.X
P4S5A/DX+
P4S5A V5.1
P4S5MG/651+
Nifty, in case anyone was interested.
