Yeah the cheapest RAM which is a commodity Apple probably paid even less.
And the Cheapest SSD available not even Samsung. It’s TLC and not even MLC based hard drive.

MacPro Must haves, HDMI 2.1 output
WiFi 6 built in
Next Gen DDR5 RAM
AMD ThreadRipper 32 Core CPU
PCI Express 4.0

APPLE will likely abandon the MacPro for The Next 3 years.

Apple RAM prices have always had a huge apple-tax for the same sticks of RAM. The RAM is going to likely be either Samsung, Micron/crucial or SK Hynix.

I wouldn't call this cheap RAM, but rather industry standard buffered ECC RDIMMS or LRDIMMS. The CAS latency is always going to be slower due to buffering rather than unbuffered UDIMM's on consumer and gaming systems. You won't be able to overclock the memory but you get much higher capacities of DRAM versus UDIMMS equivalents. Try finding 64GB or 128GB sticks of UDIMM's, 32GB sticks of UDIMMS just recently started trickling out in quantity and at much higher/faster speeds and prices.

Per this link, the ram is much cheaper (still quality), and yet Apple is putting their "apple tax" at a high markup on the sticks. Any truth to this?

Apple doesn't make their own RAM so they would putting a mark up on somebody's DRAM chips. The outrage seems to be overblown here. Dell HP workstation RAM is marked up too on their sites.

Crucial is a division of Micron . I think there is decent chance these DIMMs are USA built. ( so side step tariff drama if true ). Kind of funny if true since the Crucial system configuration thing on the site still doesn't have a Mac Pro 2019 entry.

It isn't like it is going to be hard to buy from the same source that Apple is.

does that mean I can mix and match Apple and non Apple compatible sticks in the 7,1?

Yes, you can mix apple BRANDED and non-apple branded sticks as long as they are of the same type RDIMM or LRDIMMS. You can't mix RDIMMS and LRDIMMS together. You'd have to look at the label on the delivered apple RAM to verify. Lower capacities 8gb/16gb are probably RDIMMS and LRDIMMS on the larger capacities, but you'll need to verify.

If the Mac Pro works like other workstations, if you populate all 12 DIMM slots, the memory speed will drop down from 2933 to 2666. The optimal speed is 1 DIMM per channel, and the Xeons have 6 channel memory.

MBP16,1 uses Micron (Crucial) and does not report Serial Number or Part Number in System Information. Would fully expect most machines released in the next 6 months to also use Micron as part of a volume deal.

Memory Slots:

ECC: Disabled
Upgradeable Memory: No

BANK 0/ChannelA-DIMM0:

Size: 32 GB
Type: DDR4
Speed: 2667 MHz
Status: OK
Manufacturer: Micron
Part Number: -
Serial Number: -

BANK 2/ChannelB-DIMM0:

Size: 32 GB
Type: DDR4
Speed: 2667 MHz
Status: OK
Manufacturer: Micron
Part Number: -
Serial Number: -

I was planning on using all slots. You are stating, that the ram speed will take a hit if I do so? Only use 6 slots for highest ram speeds?

Check the specs. It's common for memory to run fastest with one DIMM per channel, and a bit slower with two or three DIMMs per channel.

The slowdown, however, is almost zero for real applications - only synthetic memory bandwidth benchmarks will show any significant difference. (Real applications are usually optimized to best utilize cache, synthetic memory benchmarks are written to effectively disable cache.)

If you need the RAM, it will be far faster to fill all the slots and deal with the theoretical slightly slower speeds - rather than paging and other disk I/O to deal with the memory shortfall.

However, I'd definitely recommend using six slots of higher density memory over twelve slots of lower density memory.

You can get to 192 GiB with twelve 16 GiB DIMMs, or six 32 GiB DIMMs. If you go with twelve 16 GiB - when you realize that you need more you have to eWaste the 16 GiB DIMMs to put in 32 GiB DIMMs. I've you gone with six 32 GiB DIMMs, you have six empty slots to fill.

I don't know if it will or won't just sharing what I've seen on other *non-apple* systems. Though according to the documentation I see so far, maybe it'll all run at rated speeds.

I wouldn't worry too much about it, I'd rather have MORE ram than worry about ram speed.

The 16GB DIMMs Apple is selling in their 32GB kit appear to be SK hynix model HMA82GR7CJR4N-XN. (Edit: may be wrong)

Yo the cheapest RAM on the Market that’s like Rolls Royce using the cheapest leather on the market. They don’t even have heat spreaders or shields just a black pub

This topic is absolutely shameful.

Some of you spent months telling others that this machine isn't for them, and you need it to lower productivity time. Okay.

So you get Intel's rehashed for 5 years crap but you need it to render videos. Okay.

But now you got high latency ram and tlc ssds. So what is tlc? It means 3 bits per cell. What it also means is lower performance.

Adding bits to a single cell makes ssds cheaper, but it lowers shelf life and lower performance. TLC needs cache to stay competitive, and once it runs out, performance takes a sky dive. And it happens anytime you move large files. It's going to happen when you use final cut pro.

AFTER SPENDING ALL THIS TIME TELLING PEOPLE YOU NEED A $60,000 MACHINE TO LOWER PRODUCTIVITY TIME, YOU HAVE PROOF THAT APPLE WILL WASTE YOUR TIME DUE TO GETTING CHEAP PARTS INSTEAD OF SLC OR MLC AND YOU CHEER IT ON BECAUSE YOU CAN GIVE MORE MONEY TO APPLE!!!!!!

Just like we don't want 240Hz 1440p displays to do our real work we also don't want a bunch of RGB on our RAM, thanks.

This is server grade memory and has been designed into both the board and case with the thermals in mind, there is no need for heat spreaders.

You seem to be very confused about what this machine is, may I suggest razer.com could be more to your liking?

Follow your own advice

First of all the only reason you don't use 240hz is because of the amount of bandwidth needed for it. Professional work usually needs either 4k and/or color accuracy, and bandwidth is mostly pushed towards 10 bit color. One day you'll have 120hz and 240hz monitors.

Secondly, you can't just say 'it's server grade memory' and wave a magic wand and be done with it. Also rgb doesn't mean heat spreaders. Heat spreaders are for.. heat spreading, and were around for ages before rgb was added. The REASON why they didn't add heat spreaders was because DDR4 memory doesn't actually need them. No DDR4 modules need heat spreaders due to the low voltages used by ddr4 memory. Google it.

Seriously, some of you need to google things and quit listening to whatever website or Apple tells you. If you guys are 'professional'....

I believe he mentioned RGB because most RAM that ships with heat spreaders only have them for the looks, to appeal to the gaming community, same as RGB. Cool, I guess, but unnecessary.

I doubt anyone here doesn't know what RGB is.
