Well, 17% boost using 8 DIMMs.
So forget leaving 4 vacant.
4GB DIMMs are expensive.
667MHz works fine, 4% slower but then you would have 8 DIMMs, looks like gain of 12%+.
And 667MHz are cheap but still highest quality. 8x2GB would run $160 @ Amazon.How To Install and Remove Memory Mac Pro2x2GB FBDIMM DDR2 667MHz @ $39
Hi and thank you for your reply buddy,
Im not technically very savvy however I was under the impression my machine already comes with 800MHz sticks, that is what I would have to install.
Furthermore, assuming I was **** bent on wanting to install 800MHz sticks would adding 4 x 4GB sticks to the current 2 x 1GB sticks work fine and likewise, would I install them as mentioned in my first post?
In total I have 2 slots vacant as i have 4 x 4GB + 2 x 1GB
My Mac Pro is an early 2008 with Intel Xeon
The hatter, your last point is which I was wanting a little more clarity on. Are you saying for example 16GB occupying 4 slots in the the form of 4 x 4GB sticks performs less than 16GB spread over 8 i.e. 8 x 2GB sticks
Furthermore, what if I did already have the 4GB sticks how would I carry out the aforementioned i.e. install 4 x 4GB sticks as well as the 2 x 1GB sticks that the machine already come with
Cheers and thank you so much for putting the effort in replying to me, I really do appreciate the help
Just mix as long as they are paired (adjoin slots)
As I did not link but said, Barefeats did the tests - back in first half 2008.
4x1GB + 4x2GB
2x4GB + 6x2GB
2x4GB + 4x2GB + 2x1GB
Given $40 for 2x2GB makes it more affordable and worth it. Spend the difference on a fast or large hard drive.
