Seti@Home and Celeron P4 memory config

  • Thread starter Thread starter
  • Start date Start date

Why is there such a huge difference in the performance of the Celeron P4 CPU w/SDRam and w/DDR Ram?

[edit] Spelling fixed [/edit]
 
The P4 architecture is VERY dependant on memory bandwidth, and the Celeron (castrated P4 Willamette) even more so.

SDRAM is castrating it even more, not providing nearly as much memory bandwidth as is needed. DDR provides much more memory bandwidth, which is what the P4 architecture requires.

Also, Seti@home loves high memory bandwidth and memory speeds, due to all the data and the calculations it does 🙂


Confused
 
Same problem here. I have a 1.2ghz athlon fed by PC100 SDRAM :disgust: and it is pretty slow. I have thought about buying a ddr mb for it but I need to quit spending money on my current rig and save up for a new one.
 
Even Athlons benefit from DDR. I've got a 1ghz T-Bird, 100mhz FSB and MrFluffy has a 1ghz T-Bird, 133mhz FSB, but he uses PC2100 and I use PC133 RAM. Between the RAM and the FSB, he cracks a full hour quicker than I do.
