Hey, Fellow Crunchers!

I am new to the lunatics.at site. I know that I have a lot to learn, so I have questions to ask. Thank you in advance for your help!

I have previously used Crunch3r's apps, and am ready to use the ones on this site. However, I am unsure of which one to use.

From what I can gather, my AMD Athlon XP 2500+ would work with the SSE app in the lunatics.at Downloads section. Is that correct?

Also, how is the SSE app working out? I have tried to analyze the different tests people have run and posted here and at the setiathome site. From looking at the test runs, I'm not quite sure whether the SSE app makes an appreciable difference in performance.

Please tell me what you think! I really appreciate it.

John

Hi There,
   It's been really quiet here for the last two weeks or so, So I'll try to answer as best I can, although I am sure someone can correct me or enhance on it for you. 

If you are comparing the Chicken SSE 2.4 versus Crunch3r's SSE 2.4V they will be basically the same,  they are from the same sources, though I beleive Cruncher's is newer and *maybe* a couple of percent faster.  Also if running Vista you'd need the Crunch3r's 2.4V As I understand it (Hence the 'V')

Having said all that, I own neither Windows Vista nor an AMD CPU, so there may be more to it.

On the Other hand if you are comparing the SSE versus stock there is a fair performance difference (AMD not sure though), but not as much as there used to be because a lot of the work from the guys here filtered through to the stock application. (A good thing :D)

OK, fairly new here too though not to SETI@Home.
Vista Home Premium here, AMD Athalon 64X2
4600+ with 4 gigs of RAM. What is the best
optimized app for me to run ?

Crunch3r's page has the Vista compatible builds. For 64 bit Vista, you'd want "2.4V Windows x64 SSE2 EM64T & AMD64", for 32 bit Vista "2.4V Windows x32 SSE2 AMD".

Some addition.
If no improvement was made in 2.4V after initial release, on AMD chip you will go better with 32-bit SSE2 opt app both under 32 and 64 bit OS. It's not true for Intel, but for AMD it's so. And 64-bit os will runs 32-bit faster than 32-bit os does (Win2003 server and WinXp at least, not going to setup Vista :P )
