Just got mine going today, running an ASUS A7N8X DLX board, XP 2800+, 512 of PC2100 (getting swapped for PC3200 tomorrow), and Win98 SE (ya,ya, hey, I don't like NTFS, and still like stability). I've found it lends itself well to the overclocking crowd (better than the t-cores anyway), without unlocking the CPU, I was able to achieve a very stable 2.257GHz (aggressive settings in BOIS), more is possible with unlocking the multiplier and running full bandwidth on the memory (I had to bring mine down from 166MHz to 137MHz due to the PC2100). I had a few problems taking the CPU bus over 182MHz but 180MHz seems stabil, (not bad considering 137MHz was about as far as I could take my MP2400+, and 139MHz on my XP2100 thorughbred core CPU's. I'm sure there's moer to be had outta these Bartons, but I like just being able to RIP DVD's faster than real-time at the highest quality settings. If you're going to run WIN98 SE, MAKE SURE you install ActiveX8.1 BEFORE you install the drivers, otherwise you'll have trouble all over the place!
Happy trails
