P3 TF time
 
I have a potential opportunity to install Prime95 on 50+ PCs. They are all P3s in the vicinity of 800-1000 MHz. They'll be on about 8 hours per day Monday through Friday, so I was wondering if anyone had such a P3 running trial factoring so I would know about how long a TF would take on these PCs.

My 450MHz P3 takes around 10 days to do a current factoring exponent...

My 533MHz P3 takes 8.5-9 days to do a current TF

Oh goody, more computers. That will definately get you to the first few TF positions. As for hard numbers, I don't have any although, I got a hold of about 20 PIII's once ranging from 500-1000 Mhz and the account I put it under rose quickly on the TPR stats, sadly lost them after only a few weeks. Good luck!

My P3 M 1.2G can do a TF in about 3.5 days running 24x7

Thanks for all your responses. The provided data indicates a P3 900 should take about 108 hours to do a TF (assuming I've got the math right...). These computers belong to my middle school, so they won't be on all year, but I've estimated that for the 180 days they are active they will produce 210 CPU years worth of work in total. :shock: Note to self: install Prime95 ASAP!! :grin:

On a Celeron 1 Ghz it takes 4.25 days (102 hours) to do a current (23 million ) TF.

Frak. Someone else trying to knock me out of 100'th (again, I just got back there) on the TF rankings.

You’re in luck. PrimeCruncher is already 55th in TF. Your top one hundred spot is safe for now...

For a while I was stuck in the mid 60s. Then I got the PCs at my dad's office and my friend's house involved. Since then we've had a pretty steady climb. +11 in the last 3 months according to the TPR reports. QuintLeo, if you want to have ANY chance of staying in the Top 100 factorers, you're going to have to do better than 4.135 CPU years per 90 days. If you really want to stay on the list you should get that up to at least 6, preferably more.

My few 2.4 P4's spit that out per WEEK, if they didn't suck at factoring I might switch them over....
