konrad236 Posted February 16, 2009 Share Posted February 16, 2009 I have an Asus P5B motherboard, and I am running OSX(not sure if that matters) and I would like to add some Ram my friend gave me to the system. I currently have 2Gb of OCZ DDR2 800Mhz ram in there.(The fancy gold ones with the little ports for liquid cooling) The Ram my friend gave me is 2 non-matching 512 Ram sticks, both are DDR2 667Mhz, and both were labled by the store "Major DDR2 PC-5300 667MHz 512Mb. I was wondering, if I install this ram, will my OCZ ram be underclocked to 667Mhz? And if I install it, how should I put the ram in? Should I have the 2 800Mhz chips together, and the two 667Mhz chips together? thanks -Konrad Link to comment https://www.insanelymac.com/forum/topic/153362-mixing-ram-on-asus-p5b/ Share on other sites More sharing options...

My DDR2 PC-5300 667MHz can be overclocked to 398x2MHz. But CPU is overheated in this case, so I use 333bus clock. The RAM located at 1,3 yellow for 667, and 2,4 red for 800 to make dual channel support Link to comment https://www.insanelymac.com/forum/topic/153362-mixing-ram-on-asus-p5b/#findComment-1082263 Share on other sites More sharing options...

This is what is being read by OS X. My color coding in my motherboard is different, and I may have not put them in the right place, but my 800Mhz ram is being clocked at 667Mhz. -thanks Link to comment https://www.insanelymac.com/forum/topic/153362-mixing-ram-on-asus-p5b/#findComment-1083561 Share on other sites More sharing options...
