henry Posted August 16, 2007 Share Posted August 16, 2007 hi, i have a hp dv5237cl laptop that has intel centrino duo 1.8GHz cpu. i checked system profiler and it indicates the processor has SSE2 support but not SSE3. i know i installed sse3 during installation. why it's not showing it in the profiler? is it going to affect system performance a lot? i'm running Jas OSx 10.4.7. thanks.

Mousse-T Posted August 16, 2007 Share Posted August 16, 2007 Hello, type this in the terminal : sysctl -a | grep machdep.cpu.features ! Or try look for "Colonels System Profiler Patch" Good luck !

henry Posted August 17, 2007 Author Share Posted August 17, 2007 thanks Mousse-t for your reply. i tried sysctl -a | grep machdep.cpu.features, and here's the output from the terminal: kern.exec: unknown type returned machdep.cpu.features: FPU VME DE PSE TSC MSR PAE MCE CX8 APIC SEP MTRR PGE MCA CMOV PAT CLFSH DS ACPI MMX FXSR SSE SSE2 SS HTT TM EST again, i don't see SSE3 in the listing. i also went to the system profiler patch page. i don't think it's a problem with my system profiler though, i would guess it's a problem with the system itself. any more ideas?

Mousse-T Posted August 17, 2007 Share Posted August 17, 2007 Go and get an Knoppix or Ubuntu Linux Boot CD/DVD. (LIVE CD!) Boot via the CD and type in the terminal -> cat /proc/cpuinfo So, maybe your CPU doesn't support the multimedia commans SSE3 :-( Link to comment https://www.insanelymac.com/forum/topic/60397-sse3-support/#findComment-429629 Share on other sites More sharing options...
henry Posted August 17, 2007 Author Share Posted August 17, 2007 i checked it in vista, using cpu-z, and here's a detailed tech spec: Processor(s) Number of processors 1 Number of cores 2 per processor Number of threads 2 (max 2) per processor Name Intel Core Duo T2400 Code Name Yonah Specification Genuine Intel® CPU T2400 @ 1.83GHz Package Socket 479 mPGA Family/Model/Stepping 6.E.8 Extended Family/Model 6.E Core Stepping C0 Technology 65 nm Core Speed 1828.7 MHz Multiplier x Bus speed 11.0 x 166.2 MHz Rated Bus speed 665.0 MHz Stock frequency 1833 MHz Instruction sets MMX, SSE, SSE2, SSE3 L1 Data cache 2 x 32 KBytes, 8-way set associative, 64-byte line size L1 Instruction cache 2 x 32 KBytes, 8-way set associative, 64-byte line size L2 cache 2048 KBytes, 8-way set associative, 64-byte line size so i'm sure my cpu has SSE3 support.
