I was told there is some way i can enable SSE if ui have a dual p2 setup...wellive got one going now...im using the beta 3.25 and -forceasm -advmethods ...and still...no sse

    ROFL! You heard wrong.:D

    SSE is just an extra set of instructions that's put into the CPUs "dictionary of codes". Having a dual P2 machine rather than a single CPU P2 machine changes nothing, the P2s still don't have SSE in their architecture.

    FA is correct. P2s have no optimizations FAH can use.

    what about p3 slot 1? Do they have sse? (im looking to change this dual 450mhz to a dual 600hmz...)
    mmonnin said that the 900mhz machine would serve me better...it must have been a miscommunication between the two of yus..he must have been referring to a regualr p3 900hmz, while i was referring to a dual p2 450mhz

    Is there a way to software emulate SSE?

    Well someone asked, or was it you, whether 2 P2s total at 900 would be better than another 1 CPU machine at 900 mhz. I said it would be better for a P3 at 900mhz cause P3s have SSE. At least ones at that speed do.

    As far as I know I dont think so SimGuy. SSE, SSE, 3dnow, ednow!, MMX and all the rest are codes directly on the CPU. Software programs can take advantage of SSE, 3dnow!, etc which will speed up processes like gromacs.

    WuG. Check 'Inhell's' site or look for a review of a Slot 1 P3.
