SDRacer48 Posted October 3, 2007 Share Posted October 3, 2007 Hi all, I am currently a triple booter of Windows, Linux, and Mac OS X (as you can see below in my signature). Well anyways, in Windows XP using CPU-Z, it reports that my Intel Pentium 4 Prescott Processor with HT enabled has up to SSE3 support. But in Ubuntu Linux in a terminal window, it shows that it only goes up to SSE2. For awhile now I have just assumed that it was only SSE2 and that my Mac OSx86 was running as fast as it could, because I did not have SSE3. So I was a bought to purchase a new P4 with the same specs, but SSE3 enabled, and I decided to check mine in Windows, and sure enough it said mine was already SSE3. So that means there is something holding up my OSx86. I have QE/CI enabled. So thats not it, I guess I may just need to do a clean install and try again. Has anyone else had this identification problem, and does anyone have any suggestions to why my OSx86 runs so slow. I want it to be fast enough to compete with windows for my everyday use. *The speed of my OSx86 is comprable to my recently sold Apple G3 600 Mhz iBook with 640mb of ram. That shouldn't be, should it? Link to comment https://www.insanelymac.com/forum/topic/65239-sse3-processor-in-windows/ Share on other sites More sharing options...
zurk Posted October 3, 2007 Share Posted October 3, 2007 just compare your machine by running xbench vs mine. mine has sse3. yours should be equivalent. if its not you need to reinstall.

bibendum Posted October 3, 2007 Share Posted October 3, 2007 With a processor similar to your own, I was seeing about 99 in XBench - so the equiv, essentially, of a dual 2Gig G5...

SDRacer48 Posted October 3, 2007 Author Share Posted October 3, 2007 The highest xbench i have ever gotten is a 42 and that is with the hard drive not included.

bibendum Posted October 3, 2007 Share Posted October 3, 2007 The setup I was using when I got the 99 was this: ASRock 775i945GZ MB, Pentium 4 Prescott 3.0GHz, and half a gig of DDR2 533 ram. The 99 was without the disk test. Patrick Link to comment https://www.insanelymac.com/forum/topic/65239-sse3-processor-in-windows/#findComment-461925 Share on other sites More sharing options...
SDRacer48 Posted October 3, 2007 Author Share Posted October 3, 2007 Ok, it sounds like my install is not right then. I have suspected that for the last 5 or so months. I guess I will try an install of XxX 10.4.10 on another hard drive once I find one. Want to make sure it will work before I completely dump my working, but slow setup right now.

SDRacer48 Posted October 3, 2007 Author Share Posted October 3, 2007 Hi all, To those of you who are using linux and you use the cat /proc/cpuinfo command in terminal to see if your processor supports SSE3, it will not show SSE3 (at least not for me), instead it shows PNI which is the same thing as SSE3. So you this may improve the speed of you system if you install it as SSE2 instead of SSE3. Hope this helps someone.
