Antonio Putia Posted October 15, 2012 Share Posted October 15, 2012 Hi, I installed ML on GA-Z68X-UD3-B3 with i7 @ 3,4GHz. Everything works very well (audio, video, lan, sata etc...). And everyting seems fast (better then SL). The only thing is... It seems I have a low performance cpu. I run geek bench and gain a score of 5000 on integer and 9000 on floating point (see attachment). It seems strange because the same processor can gain over 10000 (I see it on other bench test on this forum and other ones). Now, I ask if it is possible to tune up the system (I mean cpu performance). Any idea? Thanks! PS: there is a very important difference between single-core and multi-core operation. And this seems strange... Link to comment Share on other sites More sharing options...
theconnactic Posted October 15, 2012 Share Posted October 15, 2012 Did you patch your dsdt? Which method did you use to install OSX? This is very strange indeed. My AMD Athlon II X2 dual core processor, running Snow Leopard 32-bit (with 64-bit userland), with only one memory stick (clocking 1033, appearing in the benchmarks as 533!) just got a score of 4408! Now i ran Geekbench for my Intel hack, I5 3570K, 8GB 1600mHz RAM. Got 11203, and it was backing up. It just occurs to me right now: isn't your CPU a Sandy Bridge one? I remember reading about an underclocking issue with Sandy Bridges, with them running as low as 1600 mHz. Of course, it was on Lion, i think ML offers better support for it plus Ivy Bridge support. Anyway, maybe this signals that your hardware isn't malfunctioning at all, is just some bug of the OS, and perhaps the same issue you're experiencing was already adressed.

eep357 Posted October 15, 2012 Share Posted October 15, 2012 First step, get rid of junk smbios and use one that better matches your hardware instead of MacPro 3,1 which had a core 2 quad based xeon cpu(s) Link to comment Share on other sites More sharing options...
Antonio Putia Posted October 15, 2012 Author Share Posted October 15, 2012 I simply used the classical guide for ML. That is: 1. Create installation USB pen drive with beast 2. Install ML 3. Download DSDT (same bios revision - F13) for my mainboard, renamed DSDT.aml and apply beast. Choose ALC889 with DSDT. Everything works good, but no good performance as for geek eep357, do you mean I have to try with different system definitions? Can I try to modify it using Beast, right?

Antonio Putia Posted October 15, 2012 Author Share Posted October 15, 2012 Hello Antonio Putia you use SSDT Options with i7 ? No, I didn't... Do you think I have to set it? Link to comment Share on other sites More sharing options...

Antonio Putia Posted October 15, 2012 Author Share Posted October 15, 2012 Yes Ok, I set as above and now I can reach over 12000! I set also iMac 12,2 Thanks! Link to comment Share on other sites More sharing options...

Classical guide to having problems post install, I know that guide didn't come from here. Glad you got it sorted out though 1 Link to comment Share on other sites More sharing options...
