>That depends on your app and the working set size. When you say sims, do you mean circuit sims?

Yup. Mentor and Cadence stuff mostly and some custom stuff.

Supermicro says the they're working with Qimonda to provide PC6400 FB-DIMMs

Qimonda has some data on their PC-6400 stuff,

The 2GB DIMMs are in production but it's not clear what the timing specs are. I see 5-5-5 on the web page and 6-6-6 on the PDF download.

WinTec is selling Qimonda's stuff. They don't

800 MHz with 5-5-5 looks good but 800 MHz with 6-6-6 may not be all that helpfull vs 667 MHz at 5-5-5.

Sixteen 2GB DIMMs would cost $8000 for PC-6200 and about $2000 for PC-5300. So maybe PC-5300 it is.
