Just installed Kalyway 10.5.1


My config:


Gigabyte GA-945GZM-S2 (Intel 945 chipset)

Gigabyte Nvidia 8600GT 512 mb

Intel Core2Duo E6550


That's what System profiler shows:


Название модели: Mac

Идентификатор модели: Mac Pro

Имя процессора: Intel Core 2 Duo

Скорость процессора: 1.68 Ghz

Количество процессоров: 1

Общее количество ядер: 2

Кэш L2: 4 МБ

Память: 2 ГБ

Частота шины: 960 МГц

Версия Boot ROM: Hack.int.0sh


Sorry for placing Russian information but I guess it's quite understandable


Xbench shows 104,83 and that's just a little more than my MAC Mini (93) with coreDuo.


Does someone has any idea about fixing it?

Your E6550 should be running at 2.33Ghz, not 1.68Ghz as reported.


Are you running your CPU at its rated 1333Mhz (333) FSB? From what I remember, that motherboard tops out at 1066 (266) FSB, which gives a maximum CPU speed of around that speed. (7x multiplier)

So the best for me is to change motherboard?


Yes, if you want to run your CPU at (or overclocked from) its rated frequency.



Ensure your new motherboard will do 1333 (333) FSB at least, and you are probably best sticking to an Intel chipset for compatibility with Leopard.
