Never Say Never Posted July 30, 2009 Share Posted July 30, 2009 Ok, so I've had my system up and running for a week now, and everything is stable. However, for some reason in the About this Mac or System Information, it says my RAM is 4Ghz 667MHz DDR2, when it is in fact 800MHz (PC2-6400). Does this mean that OSX is underclocking the RAM? or is About this Mac just reading this information incorrectly? In the BIOS and in Vista x64 my RAM is detected properly as 4ghz 800mhz, so I don't believe there is any problem with the RAM itself. Here are my system specs: OS: Mac OS X 10.5.7 and Windows Vista x64 Motherboard: GIGABYTE GA-G31M-ES2L CPU: Intel Pentium E6300 Wolfdale 2.8GHz Video Card: GIGABYTE GV-NX72G512E2 GeForce 7200GS 256MB 64-bit GDDR2 PCI Express x16 Video Card RAM: OCZ SLI-Ready Edition 4GB (2 x 2GB) 240-Pin DDR2 PC2 6400 SDRAM Hard Drive: 2 x Seagate ST3250310AS Barracuda 250gb SATA 7200rpm Any ideas??

Kasakka Posted July 30, 2009 Share Posted July 30, 2009 It's detected wrong, but that doesn't mean it can't be running at 667 MHz. Depends on your FSB and memory divider settings.

Never Say Never Posted July 30, 2009 Author Share Posted July 30, 2009 It's detected wrong, but that doesn't mean it can't be running at 667 MHz. Depends on your FSB and memory divider settings. Well assuming it's running properly in Vista would there be something in OSX that slows it down?

Beerkex'd Posted July 30, 2009 Share Posted July 30, 2009 It should be just cosmetic. You can fix it by using Chameleon 2.0 with a properly configured smbios.plist.
