Title: Which Optimized App for Win7x64 / Phenom II X4 955
Post by: MonsieurPoot on 13 Jan 2010, 06:15:08 am: Hey all...

I have just recently begun crunching SETI-WUs again and have used the Unified Installer for x64-Win to install the optimized SETI App from this site.
Now I know what it says during the installation process, but I kinda want to double-check anyway:

Running Win7x64 on a Phenom II X4 System, is it faster to install the generic x64-App with SSE3-Support or should I use the 32bit App for SSE3-AMD CPUs, as it is recommended during install?

Additionally I wonder, if there will be a newer optimized version soon (if that makes any sense), as the Phenom II seems to support SSE4A, accoring to CPU-Z:
"Instructions sets: MMX (+), 3DNow! (+), SSE, SSE2, SSE3, SSE4A, x86-64, AMD-V"

Thanks!

but you always can download benchmarking tool and test on your own hardware what works faster to you.
No plans for using new instruction sets yet.

Post by: MonsieurPoot on 14 Jan 2010, 05:07:39 am: Probably silly to tell you all (as you will know), but I am really impressed by the results I am getting.
WUs that take my machine around 7200 seconds to complete took my respective wingmen (who were partially running pretty fast computers) anywhere between 18000 and 23000 seconds!
I wish there were optimized apps for other projects I am crunching as well.
