Will an SSE3 install work on old SSE2 CPU?

[firebush05]

I bought a new AMD X2 (SSE3), but am RMA'ing it for lack of OC stability. The question is, should I install 10.4.6 (or 7) first using the SSE3 cpu before I switch back to my older AMD 3000+ (SSE2) CPU? From what I understand, the newer versions of OSX will run on SSE2 CPU's, but the install itself has a hard time with SSE2. Do I have this correct, or do I have everything backwards?

 

I really need to get an up to date version of OSX running on my old SSE2 CPU in order to get WiFi running. Please help me understand this. Will the newer versions run with SSE2? Will installing using an SSE3 CPU firs help?

 

Please help me... my wife is about to kill me without WiFi capable OSX. I've been trying to figure this out for months now.

 

Thanks.

From my understanding even if you put in SSE2, if your CPU supports SSE3 it will use it anyway. I'd say use SSE2 and hope for the best. Worst comes to worst, make a partition and install it in VMWare.

That's what I understand as well, but I've heard that people are having problems getting it to install with a SSE2 CPU. I'm wondering if I should quickly unpack my soon to be RMA'd SSE3 X2 CPU and install OSX to run on my old SSE2 CPU. Do you have a link for instructions installing with VMWare? I'd like to avoid that route if at all possible. This is what got me thinking of installing using an SSE3 cpu first. Guess I need to bite the bullet and try it. Just trying to avoid wasting my time if in the end it doesn't work.
