While 8GB DIMMs will work in a Mac Pro, they are a different type of memory to that which Apple sells and supports.
Got a tip for us?

Diglloyd's got some screenshots from OWC, too:

Excited now.

Ordered! Now to return my 16 gig kit.
I was really hoping for this since I use up ram like its nothing. Doing a ton of renders today ate up my 8 gigs like it was nothing :'(

Yes, In fact I normally receive shipments next day from them to my location in the Caribbean.
What eats 8GB RAM 😱
wow, your island must have an airport or a facility on that island
but that doesn't mean 8GB DIMMs will work worst. the reason why apple doesn't sell and support 8GB DIMMs has nothing to do with technical issues, i'm afraid...
APPLE!!!!
why didn't they test the 8gb sticks? this seems crazy to me, surly it would only benefit them to advertise that you can put up to 24gb RAM in to the 3.33?

Buying 16GB RAM is about 50% more expensive than if you buy it from OWC, imagine what they'd change for 32GB.

They don't care. Advertising it won't sell more systems, the people who need that much can work it out.
They would need a disclaimer saying they won't work along side the other memory they offer and that using 4 will drop memory speed to 1066MHz. That isn't Apple's style. Especially if they aren't going to sell it. The other thing as I mentioned before is that it is not supported on the platform by Intel, Apple don't stray away from Intel's spec, nor do most manufacturers.

using 3 modules shows a ~ 15% memory bandwidth gain over 4 modules, so the configurations with a * at right ar the optimal ones. Whether real-world tasks are affected by this small difference remains to be tested, but in past testing I never measured more then 3% hit from using 4 modules instead of 3.

The Xeons have integrated memory controllers, Apple can't do anything about it. If it exists, it works. The Xeons just need ECC RAM, which couldn't be manufactured in 8GB/Stick.
The reason Apple doesn't offer it, is because they rip you off with their memory prices, and it would get obvious if they charge you $7000 extra for a 64GB BTO option, which would cost $2850 at OWC, while keeping the 6GB which are also worth $200 or so.
Apple BTO is a bad thing, buy stock and upgrade hard drives/SSD/memory(/Sometimes even CPU) yourself.
Btw. using ECC RAM is BS anyways, as long as you are not located anyways near radiation (MRI/X-Ray) or cosmic rays.
NewEgg has 8GB ECC sticks for $290 rather then the $370 OWC charges you.
This is not PowerMac anymore, MacPros take every RAM out there due to the memory controller inside the CPU.

2x8gb
I ordered the Hexacore last week (still waiting for it to ship)...
Was going to get 3 or 4 x 4gb but now leaning towards using 8gb ram for future expandability. Dont really want to drop a grand on memory though.
All this talk of triple channels seems overly confusing.
Can i use just 2x8gb (not really sold that way on OWC) and add a third latter if it seems necessary? Aam I better off getting the 4gb ram for now?
Thanks for your help.

How does Crucial compare with OWC?
Oh, and why does Crucial not have any x3 8GB kits. They only offer kits of 2x8, and 2x4. Why no 3 stick kits for maximum performance (triple chan)?
Thanks

Well, the cheapest RAM which should be available worldwide is Kingston ValueRAM DIMM 8GB PC3-10667R reg ECC CL9 (DDR3-1333) (KVR1333D3D4R9S/8G).
Search at your local "Lowest Price"-website for it.
It's RAM, it has lifetime warranty, it's fine.
Because you don't need dual/triple channel kits anymore, you can even mix DDR3-1333 ECC over different brands as long as they have the same specs these days. A couple of years ago, as you needed the exact same DIMMs for Dual Channel, these kits were more expensive then two same-model bare DIMMs, because they assured to be the exact identical DIMMs. They are just a leftover of those days, today you can just get any DDR3-1333 ECC CL9 and mix them, they still work in triple channel.
If you ever had a PowerMac G4, you'd just get the cheapest RAM with lifetime warranty for you MacPro. Every tried to find low-density PC133 these days?
Im waiting on Transintl pricing. Actually going to call them in a bit to find out, and perhaps change my order for the 50th time lol
I was hoping for a 24gb kit from crucial. How are Crucial compared to OWC in quality and performance?

Your eyes just don't work right.
As for the comparison: It's RAM, it has lifetime warranty, it's fine.
Sorry, I was looking under the Apple 6 core section on Crucial's site which doesn't offer 3x8. I didn't realize you could buy any ram on the site if it was not listed under the specific computer model.
So, why is Crucial so much more expensive than OWC, and does that RAM yous showed include the thermal sensor that the Mac Pro requires?

OWC are just selling to Mac Pro users really, they may make very little profit on memory in order to build brand awareness and hope you buy other more profitable things from them. Crucial are the retail brand for Micron which is one of the big 3 memory manufacturers, they are moving in many more markets and their brand is much stronger. I doubt many people know of OWC outside the Mac community.
