Which hardware on a nMP base model goes obsolete first?

Not the "faaaar future" - but yesterday.

Memory is tight on my 128 GiB Dell T1650 (same CPU and chipset as the MP6,1 hex core).

I'm looking for proof that 32 GiB LRDIMM modules work on this system, so that I can bump to 256 GiB.

You fall into the special needs category

All this talk of faster SSDs in the nMP is silly. Honestly who cares if there's only one drive in the machine. You shouldn't be using your boot drive for anything other than boot and apps and maybe your home folder and mail etc...

Any assets, project files, scratch, whatever goes on other disks. SSDs are plenty fast enough for OS. How much snappier do you need Safari?

What they NEED to do is make the damn thing larger and put in a second CPU and more separate drives.

Perhaps, but from the beginning the topic of using 32 GiB LRDIMMs in the MP6,1 has been active ( https://forums.macrumors.com/threads/1698707/ ).

LR-DIMMs are not supported on E5-16XXv2 Xeon CPUs or E5-2687Wv2, so they should not work in your system regardless of your chipset or BIOS/EFI.

32GB HyperCloud DIMMs might work. Look for IBM part number 46W0767. They do boot in late 2013 Mac Pro and they run at 1333 MHz, unlike regular R-DIMMs which would run at 800 MHz with my 12-core CPU. I don't recommend them for the late 2013 Mac Pro though. More info in https://forums.macrumors.com/posts/20777838/.

Good point - I was thinking about the denser R-DIMMs, but typed LR-DIMM.

Incremental?

I've seen some of the results of the SM951... 1400-1500MB/s is very good... about 11-19% improvement over the 1TB in the nMP which hits 1260MB/s in my nMP (and I've been enjoying that performance for over a year already). I'm sure a refresh to the nMP will bring the 951 and PCIe 3 so it should get even better. Whether that offers anything more than an incremental improvement in any real-world benchmark or task remains to be seen.

You should check what part you have. Barefeats has now verified a 40-50% speed increase in the new drives. If you were really near 1260MB/s you may have a special drive.

In the nMP SSD speed depends on capacity. The 1TB drives are faster than the lower capacity drives.

You should go read the test.

On my phone ATM but will check it out. I benched mine at 1260MB/s large sequential reads or writes (don't remember which) with QuickBench. I'll look it up.

EDIT: I see Barefeets is testing a 512GB drive... as I said, the 1TB drives are faster than the others.

Here's my drive...
