DDR Athlons and SETI?

[Rendus]

From what I remember of SETI, it loved the larger cache processors, but since those don't exist -edit: anymore, other than Xeons- I'd be led to beleive it'd eat memory bandwidth like candy. Has anyone gotten a chance to try S@H clients on a DDR Athlon system and compare it to a normal SDRAM system? How'd the DDR system fair?

I'm likely to get a DDR TBird system pretty soon (mmm.. credit) and think it'd be better equipped for SETI than RC5. (That and all the spaceheaters listed in my sig are all running RC5 🙂)

Seti definitely loves the memory bandwidth much more than RC5. But ive heard taht the newe client 3.0 is much less dependent on memory bandwidth(Please correct me if Im wrong). But all in all I think the DDR/Tbirds will kick ars in anyone of the projects. Especially since they have the highest KKeys/mhz in the distributed computing projects(except for the macs of course) man only if they could ramp up macs speed. That would be some serious firepower.

here you can find the first (and only) information about ddr and seti that I have been able to find.

The DDR memory will definately help SETI.
While testing different configs, PC133 ram was about 10% faster than PC100. CAS2 memory was also about 5% faster to.
So bump that DDR to 266 and you should see a healthy gain. Estimations have been around 10 over regular sdram.

From what I remember about that post was that reading somewhere else the reference board couldn't enable DMA on the drives and that was limiting performance.
