Hmm.... I know it seems to be pretty quick in any computer I put the memory in. That PIII I had the ram in before ran REALLY well. Of course, it has two processors, but even after the second cpu broke, it still worked pretty good. I wouldn't be surprised if it handled memory better then DDR.
I see someone on ebay has 1gb of that stuff up for a bid of 215$, with 27 bids. I'm glad I didn't have to buy the stuff.
