It kind of works that way already. With 64GB of RAM the OS will use most of it to cache the disk. Very soon you will have most of the files you use in the cache and you will have the effect of a RAM drive. And the OS will of course save the changes to disk.

a RAM drive is a bit obsolete except if you are running on a very small computer that boot off a USB stick.

Oh dear. How long will it take El Capitan to go to sleep/shutdown with 64GBs!? My puny 8GB MacBook Pro is sometimes taking over a minute to go to sleep since installing EC. The times were way shorter with Yosemite (like 15-20secs or less after about 45secs with Mavericks). I'm guessing it's the hibernate thing, which I haven't tried turning off since installing EC (never could get it to stop writing the hibernate file or stop waking up when the power cord was plugged in/unplugged with Mavericks/Yosemite).
 
Stupid question- but having 64gb doesn't some how slow the machine down does it? Or, better question- are there any bad sides to 64gb of ram?

Very interesting to hear that. My 16GB iMac goes to sleep instantly with EL Captian. Did you do a true clean install? I did a complete erase and install and manually installed my apps. Not a hitch of slowness......except for iMovie that needs an upgrade from Apple.
 
Why is Apple RAM and SSD more expensive than the very same product from the manufacturer?

Because you're paying Apple to install it in their own machines directly from their factory. Otherwise known as labor costs. Oh you might say, "I can install Ram and SSD's by myself"? Well for every 1 person that can install Ram and Storage upgrades there are 10,000 more people that either don't know how or simply won't. For that reason Apple will charge more. Be real about it, if you were the head of a computer corporation that caters to a large consumer base with zero computer knowledge you would charge accordingly to profit your company as much as possible. It's business. If you feel otherwise you would be out of business very soon.

Why does Ford, Chevrolet, and all other car manufacturers not sell cars at their cost? Greedy manufacturers!

Come on man, at least provide an answer that makes sense rather than an ignorant quick reply. Always the quick answer around here, "Apple Is Greedy". What company isn't? If that's your only way of thinking then don't buy.

Wow OWC seems to like their RAM as well as Apple. $1200 for 64GB?

Seems they have some exclusive distribution agreement and are taking advantage.

a suitable 32GB kit from G.Skill (4x8GB DDR3-1866/2133 both skylake compatible -skylake is the same on PC as on Mac, so if it works on a PC based on skylake will work on a mac too-) cost 224$ on amazon, I will order it, when I need 64 GB sure OWC is not the only DDR3-1866-16GB supplier.

Those are slower chips and only 2 rather than 4.

The OWC offering is 4 x 16GB 1867MHZ PC3-14900.
64GB from Newegg is $760 compared to $1200 from OWC. Is $440 more worth it going from 1600mhz to 1866mhz?

You can't defend the outrageous pricing of OWC memory.

That is interesting. Yeah, cleaned it down to all zeros, then reinstalled everything from scratch. It was really good on Yosemite, but not now. I'll poke around some more. Maybe I'll put in another disk drive and do it all over, but try shutting down after each application install. It could be some incompatible application, but it sounds like it's just writing up a storm while it's going down and not just sitting there. Thanks!

I just double checked. It was about 10 full seconds from clicking the sleep button to hearing the computer click off. About the same as it was on Yosemite for me. Hopefully you can get this ironed out. :)
 
I'm really curious what uses someone could have for 64GB of ram on an All in one desktop :p

I can barely put a dent in 16gb of ram, except when running VMs

Apparently my sarcasm whooshed over you. I was mocking others that reflexively use that phrase thinking Apple should not be making a profit.
 
$1195 for 4x 16GB???? This must be a misprint. Surely no one is stupid enough to pay that much when you can go to new egg and buy a 16gb stick for about $100 bucks or so!!!
 
64 GB of RAM? Sheesh, it's about time! Now I can finally load up every single instance of PLAY and Kontakt and not have a hiccup... Eh, or just take the $1000 some odd dollars for the ram and purchase some PCs with the samples loaded up, each with 32 GB of RAM and SSDs and have it wired through ethernet via Vienna Ensemble Pro....Eh, or just buy some brats and a grill....option 3 sounds pretty good.

I'll never say no to more RAM when it comes to complex vector files or huge layered bitmapped PSDs.

64GB is good. It may seem like a lot, considering most PCs will run fine in 4GB (we have plenty of them at the office that do), but in Pro or server environments, 64GB is only slightly above average. We have 128GB in many of our servers, and some of our newer HP servers can accommodate over 1TB of RAM (although we haven't tried that yet). $1200 for 64GB is certainly excessive. Crucial has 16GB PC3-14900 SO-DIMMS for about $100 ea.

What is crazy-ass stupid is soldering on the RAM in the 21.5" iMac, and including 5400 RPM hard drives (in any model). I can't even begin to find the words to describe how freaking stupid that is. Stupid and pathetic.

The iMac isn't a server though. It's not used in the same way or intended for the same audience. There are so many ways they're totally different beasts. I don't see many iMac users having a lot of need for 64GB of RAM. If you have a real need for it, the architecture of the Mac Pro will be far better suited.
 
I always wonder why Windows people come to a Mac-enthusiast forum. If your "dark side" is so good then why be here? At times Windows people appear to be threatened by so many people that have cut Windows out of there life and have been enjoy the Mac experience. And they say Mac users have a cult. :rolleyes:

First of all... the "dark side" thing was a joke. Lighten up. The guy I replied to specifically mentioned Windows in his comment. I'm allowed to speak to that.

I love my iPhone and iPad... that's why I'm here. But I also love the powerful desktop Windows machines I can build, literally build, choosing the specific hardware I want.

If the Mac works for you, then fine. I honestly don't care what you use.

But there are some times when Macs don't work for you. He was complaining about Apple's odd hardware configurations. That should be a strike against the Mac experience, right? Go read his full original comment... he's clearly not too happy with some of Apple's decisions concerning hardware.

I simply gave him some perspective from another angle. Which, again, I'm allowed to do.

That is correct. I wasn't trying to insinuate that an iMac is a server, I was only using servers as an example of how 64GB isn't a whole bunch considering other possibilities. Most desktop PCs (of any brand) can't accommodate more than about 64GB, up to 128 in some cases, but in server land, it is simply amazing that the plunky x86 platform (in Xeon flavors) can push upwards of 1.5TB of RAM now (costs more than the server itself). :)
