I just installed my 2.4c with hyperthreading. I was running this setup at 3.475 with a 1.8a and doing WU's in 2 hours. Now I'm running a 24c with hyperthreading at 3.485 and doing WU's in 2 hours 45 minutes. Any idea why its slower?
Are you completing 2 WU's in 2:45?

I didnt check for that. That would be nice.:D
Sounds about right. My 3.06@3403 is doing two units about every 2 hrs 50 mins, roughly 16-18 per day.

Im just going to have to get one of those 3.06 cpus.... I hear the albatron px845 pev just loves that cpu.....

That's a good board, but for hyperthreading you really would be better served with a dual channel ddr board.

TC I just dont know that Im sold on dual channel as of yet. I havent played with it on a intel base board yet. (shame on me) But I did just last week on my 8rda epox xp1700 rig. Given I didnt have the best ram in it ,,, it was a near waiste of time.... I lost 21 mhz fsb on my oc.... and truth be told,,, I couldnt tell a thing about it. But I dont think much of this amd build so who knows,,,, some think Ive missed the boat all together..... lololololol

Dual DDR is the way to go. You need good RAM to make sure you don't have interactions between the DIMM's.
...but that isn't really tough the way RAM prices are going lately. I've been really pleased with the Kingston HyperX products.
I've tried dual ddr on my a7n8x and it was a waste of time, but it's truly an impressive setup on the intel platform - the difference in scores via sandra is thousands of points higher.
Practical, with the P4 3.06GHz AND HT,I gained a REAL 30% MORE crunching time. HT works just FINE with SETI......... ;)

2.4's do not support hyperthreading??? only 3.06 and above....

yepp just saw that, the new 800mhz chips - did not know they were on shelves yet
2.4 / 2.6 and 3.0.

i'm all set and ready to build a version "C" HT enable Intel army as soon as they are on the retail channel (w/ reasonable price that is!)......:cool:

2.4 / 2.6 and 3.0. The 3.0C - that's what I plugged into my P4C800 this afternoon. Haven't had a chance to test it thoroughly yet, but it gets into windows okay at 3600 with 1.63 volts using the retail box hsf. It seemed a little flaky running Seti so I backed it off to 3450 so I could run my xms 3200 at full speed. So far with 2 work units done running a single client at a time it's averaging 1:46 and appears to be edging lower. I'm going to water cool it this weekend and perhaps that will allow me to run 3.5-3.6 stable, but I'll have to drop my ram down a notch. I can't complain though. Seems to be crunching about like a 533fsb chip would be at 4GHz+ The faster bus really makes a huge difference, and this canterwood board is a pleasure to work with.

I'm glad your enjoying your P4C800. Should I run my seti single client at a time for more WU's?
No you get more production per day running 2 clients as long as you have HT enabled. If you're going for the fastest benchmark time turn HT off and run 1 client.

OK thanks TC.
Are we talking about the same thing? The P 4'C' variant does not support hyperthreading.

The P4 "C" 2.4GHz , 2.6GHz , 2.8GHz , 3GHz and the upcoming 3.2GHz support Hyper Threading......All of the 200fsb CPU's do..... ;)
Seems to be some confusion here - the A was for 100fsb chips, B for 533, and now C for 800. All of the C desktop chips support HT. This "C" laptop chip is new to me.

a 2.4c i saw was $20 more then a 2.4 regular @ one place.
224$ was the price i beleive for the 2.4c 800mhz
to me that is afforadble and VERY temping!!!! to get a new board /cpu
