Possibly your 266 MHz DDRAM is CL2 but your 333 MHz DDRAM is CL3. Or perhaps it's the asynchronous operation of the memory, which may increase latency. The increased memory speed per se does not help, because bandwidth is limited by the 266MHz FSB. I would suggest that the memory controller is the issue here.

The 1% improvement probably comes again from synchronous operation. > Regards > Brian Beesley Daran G. _ Unsubscribe & list info -- http://www.ndatech.com/mersenne/signup.htm Mersenne Prime FAQ -- http://www.tasam.com/~lrwiman/FAQ-mers

Personally, I'm unable to contact the PrimeNet server. At first, I thought it was an issue with the firewall here at school, but once I authenticate to it, I can open another browser session (or even an entirely different program) and stay authenticated. I can also use any other program, e.g. instant messanging clients, without problems. Also, I had no issues last year when the firewall rules were in some ways, if anything, stricter. My hunch is that the server is having problems, and some accounts that would normally have contacted in the last few days and have been listed as still active were instead placed on the inactive list in the server stats.

Mersenne: Are We Losing Members?
On 23 August, we had 18021 accounts and 31701 machines, per the website. Today, 4 days later, we have 17916 accounts and 31511 machines. We lost over 100 members in 4 days, and almost 200 machines? What's up with that? We've also done only about half our usual throughput today.

Possibly your 266 MHz DDRAM is CL2 but your 333 MHz DDRAM is CL3. Also, I have two near-identical systems using 1.2GHz T'bird Athlons in Abit KT7A mobos, with CL2 PC133 memory. The only difference is that one of the CPUs is 200 MHz FSB the other is 266 MHz. Both are running the memory at 133 MHz (the BIOS on the KT7A lets you do this). The system speeds are within 1% of each other.
