How much RAM do you have installed?

48Gb

 

Voted. Only have 16Gb.

 

Same.

 

16GB, will have 64GB once I get my hands on the trash can Mac Pro.

 

64gb in 4x 16gb chips. Will probably grab 32gb more as my needs escalate.

 

Since it's a picture thread

It looks like the vast majority of us will not miss the extra 4 DIMM slots

 

...assuming the 16GB DIMMs come way down in price, sure. My 48G is done with 6x8GB.

 

They're not to bad actually mine ran about $140 each.

 

64gb

 

Same amount as yours. But I got it $109 each

 

Not bad at all

I remember just a few years ago, a 1gb stick was over 100 for my mb

 

But I don't live in the states, I probably cold have trolled ebay until I found it cheaper but Jürgen always takes care of me so I'm good with the price.


What kind is it and where did you find it? Is it dual rank or quad rank?

No kiddin..

I think RAM has stopped it's downward spiral though for a while..

 

Kingston has 32GB DDR3L ECC DIMMs available, albeit 1333MHz CL9. They may or may not upgrade them to 1866MHz.

 

Normally....

64 GB. But in some occasions I go up to 96 GB....Never tested throughfully the 128 GB "magic limit"....

 

I have 48GB and its been a real treat to never, ever run out.

I bought the box stock with 16GB and quickly realized I needed more. I don't push the machine hard often, but when I am doing a few data intensive things at once, its nice to know it slices through it without any hiccups.

I'm likely to do the same on the new Mac Pro, unless I can get 64GB cheap enough that I can justify it.

 

And they run about $750 each

 

32GB (8x4GB). Only cost $275 before the $AUD tanked against the $US. Only utilized the full amount opening a 26GB image file from a Leica microscope in an XP virtual machine. Usually have about 22GB free most of the time.

 

32 as in 8*4

 

4GB - 2x1GB and 4x512MB. These are FB-DIMMs (somewhat obsolete, expensive), which is why my Mac Pro has so little RAM.

 

48GB... but it's overkill for me

 

That, too.

But actually, four DIMMs is the right thing to do if you look into the future.
The next step after DDR3-1866MHz is DDR3-2133MHz, and the new Mac Pro likely runs that already if you happen to find suitable modules. Afterwards, you run out of JEDEC specifications for DDR3 and get to Haswell-EP Xeons at some point, which should look something like this:


It comes with Quad-Channel DDR4, and that allows only for one DIMM per channel. DDR4 also won't set you back $750 for a single 32GB module.
