I know there are a few people on this list } using this mainboard, so I thought I would pass the info on. I have } not done a make world yet. All times are in seconds. Thanks a lot. This information is much appreciated! I've been thinking about buying a Tag RAM for some days, but I still need to find a local source. What is the exact chip type you bought (and what did you pay ? Seems they are soem $20 over here ...) Could you perhaps give "bytebench" a try ? I've done several tests with WT and WB without dirty tag RAM, and I'd be interested in numbers for WB with that chip added. I found the AMD 5x86 to be 150% of an DX2/66 (user and real time of a make world), and the tag RAM would make that 165% !
