>>bandwidth, but about the same latency with DDR - so i suppose i'm better off
>>buying SDRAM for my application. any opinions of the experts?

I recently bought two mainboards with 512 MB RAM each. One ECS K7S5A with SDRAM
(Ifinieon PC133 CL3) and an Asus A7V-333 with DDR RAM (Samsung 333 CL 2.5). On
the first one Crafty was faster. I have no idea why.

XP2000, K7S5A, SDRAM
Crafty v19.0
