Q: RAM speed and usage on a PowerMac

I have noticed that my machine recognizes the two different RAM speed currently installed on the computer. The RAM that came with it is 30330 and the OC2 RAM I got, a faster 25330.

The question is, would the machine use the slowest (or a default) RAM latency based on what's on its bank or would it use the speed based on each memoy stick?

The question is to understand - is it worth it getting faster RAM for the machine (and maybe eliminating the two sticks that came with it) or is it just a confort level (getting better, faster RAM) and 30330 is just fine?


Also, is it ok to mix and match RAM brands? 2xSamsumg, 2xOC2, 2xKinston (paired) for example?

I'd say the difference will be marginal but you MAY be able to test if you are careful using Xbench.
Shut the machine down- do a ram test only or maybe the first couple of tests in the suite.
Do this twice ( don;t shut down in between ).

Then remove the slower ram and repeat under identical conditions.
I'd be interested too. Make sure you do double tests.
