Ram after CPU upgrade

[Pjotr28]

Hi,

A W3680 is on it's way to put in my 2009 Mac Pro. In the research I read that the W3680 will recognize 1333 mhz ram. At the moment the Mac Pro has 12gb 1066 mhz ram. Will I notice a big difference between the two? And when I upgrade the ram to say 16gb can I mix 1066 with 1333?

And at last is 16gb enough for major FCP X editing and bit of Motion and After Effects?

Thanks.

Your processor swap does not change the memory requirements. Leave RAM at 1066 MHz. 16 GB is OK.

Yeah 16GB is just enough... Assuming FCP is all you run the it's for sure enough. I always seem to have other (needed) things going at the same time which often makes 16GB kind of a bare minimum.

But RAM is so cheap right now that as long as you're increasing the amount anyway, why not hit the 32GB mark - which really is enough.

The more the better I know. But can I swap two 2gb 1066mhz for two 8gb and leave two 4gb in? Gives me 24gb

Yeah you can do that.

If me I would sell the 4GB modules and get 3 8GB modules instead tho - doesn't your machine like RAM is groups of three? It's about a 2% increase in speed with less fragmentation (err, bank addressing...) issues IIRC.

Right? you have one processor - 4 cores? Or is it a dual?

He would have a single proc hence the W3680. As for ram, get more than 16gb. I am constantly paging out using the programs you use, Well mostly Adobe stuff, Premier, AE, PS. I would suggest at least 24gb.

Yeah it's a single processor 4.1 2.66ghz. I'll have a look at the 8gb. Not the ones at the Apple store € 305 a piece

Of course not. Buy used server RAM off EBay for 1/3 the price.

Just make sure there's a 2 week return policy and spend the 1st 24hrs running 4 instances of Rember.
