My system is a Mac Mini 3.1 (late 2009)

OSC = Maverick 10.9.2 (13C64)

HI BDAqua


Thanks for your suggestions.


I have already installed "Trim enabler" with no help. I did remove this program and installed the "chameleon".


This did not fix the issue as it is still:

Hi Again


I have now updated the Samsung 840 EVO firmware to newest version.

This did NOT help on the speed..

This concluded following:

installing and enable Trim via Chameleon and updating Samsung SSD 840 EVO firmware to lastest version EXT0BB6Q, does not increase nagotiation speed from 1.5Gbit to 3Gbit.


:-(


Does anybody have a fix for this issue?

Hi again..


A bit more info: I have seen the speed go up to 3Gbit, maybe 1 out of 10 boot ups..

If i then reboot the Mac mini then then speeds goes down again to 1.5Gbit and i cant reproduce the scenario for getting the 3Gbit.


This was seen with both with and without "Trim enabler and Chamaleon installed" and before and after update of Samsung SSD 840 EVO firmware.

well I have seen the same issue for MACBOOK pro infollowing thread

https://discussions.apple.com/thread/2053097?answerId=9689928022#9689928022


Here was the fix installing the EFI and SMC 1.7 Firmware.


For Mac Mini 3.1 the EFI and SMC firmware only goes up to ver 1.3..

http://support.apple.com/kb/HT1237?viewlocale=en_US


Anyway i will check the EFI version and update if needed..
