Is it working Pt2

[Zaphod]

My two dual core machines now show version 5.17 is this the sse2?

Installed sse2 on my Sempron 3000+ and it seems to have killed Seti.  Get the standard windows message;  Initial Release has encountered a problem and has closed.

Should I reinstall basic Boinc?

Also, have Celeron 664 machine, is there an enhanced for this machine?

and have Celeron 2.2G machine, same version?

Some Sempron's are actually Athlon XP's (Thoroughbread). I myself have a Sempron 2400+, that is actually an AthlonXP with 1667MHz stock speed.

The XP's only support SSE. So trying to run the SSE2 client on such a processor, will result in an error.

Try running a program called CPU-Z (find it via Google), it will tell you what capabilities your processor has.

It should be allright to just install the SSE version on top of the SSE2, restart BOINC, and it should work.

Core was a Barton,  sse (not sse2) is running.  Thanks

Need suggestions for  Celeron 664 machine and Celeron 2.2G machine

Celeron is such a bag of troubles.

There are at least 4 kinds of celerons.

Pentium III celerons which do SSE only.

Pentium 4 Celerons (early) do SSE2, but maybe SSE is faster.

Pentium 4 Celerons (middle) with full SSE.

And I believe even some Pentium M's that were made Celeron.

Celeron basically means..."Full Intel Chip which had some parts fail during testing on the wafer fabrication, and which were sold with parts turned off".   Less L2 cache means that there was a larger cache on the chip but there were errors in the remainder of the cache...etc.

And Celeron D which does SSE3 too  .. So there are several versions..

My Sempron 2800+ Socket 754 next to mee is even a SSE3 chip .. So there are several different versions even on the Amd side.

Don't forget the original P2 Celerons which do only MMX

Still, the CPU-Z route is the easiest to take. http://www.cpuid.org/cpuz.php.

Download and run it (no installation necessary) on all the computers first, and it will tell you what they support (SSE/SSE2/SSE3). Use the highest number SSE version supported.

HTH,
