The SMP client shouldn't be used with that processor because it is only a single core processor and the smp client is designed for multiple cores. The benchmark machine for folding on a single-core folding client is a 2.8GHz P4 (with SSE turned off). It should produce around 110 PPD. Since your processor supports SSE and is slightly faster it should do somewhat better but still it just is not a very capable processor compared to modern chips.

Are you freakin' serious? Well, at least everything is making sense now. Sucks that I've been thinking I'm running a dual core for these past five years, haha.

Quick question: Why is it then, that when I boot up FAH, it says that it detects two cores? Just wondering.

5 years with a P4?!

He could have a Pentium D550 3.4Ghz dual core processor. The processor number and cores correspond with his expectations. GPU-Z would confirm that he has this Prescott version. My 2.8Ghz Pentium D dual core was earning about 1000 PPD but only after I obtained a Passkey.

Hardware configuration: Several dozen Core2duos and i3s at a Mental Health organization. About six i5 at home, including a GTX 1050ti GPU that does half the total points.

The Pentium 4 550 was introduced in 2004 so it is fairly old in dog years.

It draws 115 watts so it will be fairly expensive to fold on.
It is a single core with Hyper threading, so expect about a 15% boost over pure single core.
It has a 1 meg cache, so a more modern CPU may run F@H much faster (if the entire program fits in cache, it never slows down for main memory.

Please do not revive 6 year old topics. The information is not relevant to the currently available client software, and pretty much not to any current folding.

P.S. If you read the previous posts in this topic, the original poster did check and he did post that he had a Pentium 4 550, not a Pentium D.
