Recently, 32GB modules are sold very cheaply on Japanese auction sites.Awesome, I was already wondering if it would work with all 12 slots filled with 32GB DIMMs
Any tips on sourcing them cheaply, though? I got a nasty bit of sticker shock when I looked them up...
I got an Xserve2008 the other day.
however no memory, so I got 8*HYNIX 2GB 2Rx8 PC2-5300F-555-11 and 4*SAMSUNG 2GB 2Rx8 PC2-5300G-555-11-80.
but it won't boot (LOM panel keeps blinking blue, so I think the memory might be not compatibl.)
I also owned a 2008 (XS2,1) before, but I forgot the memory specs. Please tell me the correct spec.
...
DDR2-6400F??
This is correct, but only for the 2009 models (Xserve3,1). Stcm went slightly off-topic by asking about the 2008 (Xserve2,1)You need 240-pin PC3-8500 (1066MHz) DDR3 ECC SDRAM for an Xserve. They may work with non-ECC memory or memory that is slower or faster than PC3-8500 (1066MHz).

I see. Thank you for your adviceGiven the lack of pcie lanes on the mxm slot I’m not sure you’d gain anything from something better than the wx4150 for mxm anyways.
+1 what Ludacrisvp said. Lack of Pcie Lanes on the MXM slot (only 2) heavily bottle neck even wx4150.
Have a read here where we compared my rx560 score to the xw4150mxm post #61 on this thread.
Keep in mind they should be almost identical in specification. Within 5%,
MXM to NVME adaptors exist? Now that would be very cool if they work for the xserve. Hope the experimentation goes well.
I Agree. I suppose the ultimate test would be to run a mxm wx 4150 on a full lane mxm/pcie adaptor.On one hand I do wonder if some more controlled testing with alternate vbios for the 4150 may have helped with those numbers but in any case I’m sure the lane count was quite restrictive to performance.
in theory this card should work, and if you’ve crossflashed to Mac Pro firmware or modded bootrom for NVME booting this should “just work”

I did look for mxm pcie adapters but all of the ones I could find were single lane pcie 1x for mining operations.I Agree. I suppose the ultimate test would be to run a mxm wx 4150 on a full lane mxm/pcie adaptor.
But, confident as you are, the bottleneck is the number of pcie lanes.
Yes, I've been running the last 144 mac pro firmware for a while with dual 6 cores.
That adaptor is a gem of a find. Thank you!
Ordered it immediately, will be a month at least before it arrives.
PCIe 2.0 x 2 Lanes should get us up to a theoretical 1000mb/s max. If the adaptor works well we could get near that speed.
Much faster than we can reach on SATA SSD. around 150mb/s.
I'm getting around 1500/1600mb/s. currently on my pcie nvme adaptor.
Using a kryoM.2 evo PCIe 3.0 x 4 Adapter and a Crucial P3 2TB. (Thats 4 lanes)
All that said i boot using my sata ssd's. That hits close to 150mb/s. So not worried if it boots or not.
Sata maybe slightly lower boot times, but, still feels snappy. I prefer to have working data and OS on different drives.
Amazing!!
Adaptor arrived and it works. Which is fun! Have not tested if it works as bootable drive. If anyone cares let me know i can probably test it.I did look for mxm pcie adapters but all of the ones I could find were single lane pcie 1x for mining operations.
let us know how it goes with the adapter.

Speed is around 400mbps. Way faster than sata, but, absolutely destroyed by the Kyro M.2 evo PCIE card I've been using.
here's some ATTO disk benchmark results for comparison.
(This is with the same Crucial P3 2TB.)
Massive performance difference.
I've also included the NVME express info from system information.
Just show up as "Generic SSD controller" Trim is enabled. Link Width: x2, Link Speed: 2.5 GT/s
Overall happy with the purchase. Would have liked to have seen about twice the speed. There are some jumpers to play with on the mxm card, nothing in the instructions about them. Maybe that will unlock some performance.
Another possibility m.2 to full pcie riser? Be great for some USB 3.0/3.1 Cards.
I am not sure about@startergo might you have thoughts on if that would work (attempting to set pci speed).
setpci
. That would be @joevt.I am still running mac pro 5.1 144 firmware. 12 cores won't post without itare you running Mac Pro 5,1 144 firmware or Xserve still?
if Mac Pro you should be able to boot natively from the NVME drive. If Xserve then you’d need to add the NVME driver.
Yes conceivably you could use an m.2 adapter riser card to run a full “normal” pcie card from it.
sounds like the MXM slot is running pcie 1.0 speeds with 2 lanes, Because a pcie 2.0 slot would say 5.0GT/s which is why you’re getting about 1/4 of the speeds. Still potentially better than many sata drives and possibly a better use case vs a GPU depending on what you’re using it for.
id wonder if one of those setpci tools could run the slot at 2.0 or if it really is just a 1.0 slot.
@startergo might you have thoughts on if that would work (attempting to set pci speed).
thanks for this, I had a quick read, installed the efi driver and added if to my OCLP created config.plist in opencore.

Has not changed link speed yet.
Will have another read and try again.
