NVMe Blade too slow in CMP?

[Roadmap123]

My Config:

cMP 4,1 -> 5,1 equipped with Samsung 970 pro on Kryo m.2 Adapter on Slot 4.

Nothing unusal, runs also with injected 138.0.0.0 fine, but I saw a lot of benchmarks with speeds over 2GB/s, mine is quite slower, see here:

I also don't see any misconfiguration:

Anyone an idea?? Thanks!!

Mac Pro 5,1 only has PCIe 2.0, top at 1500MB/s. Yours is the expected throughput.

To get more than this you need a PCIe x16 adaptor with a PCIe switch that converts PCIe 2.0 x16 into PCIe 3.0 x4, around $400 for HighPoint SSD7101A, more for Amfeltec Squid.

Hey @tsialex,

you again

Thanks for explanation. So all those guys showing their benchmarks on YT are using a 400 Bucks Card to retain this Speed

Another Question: I see in those Videos Boot-Times in some seconds.

My cMP takes about 60 Seconds to boot up 10.14.
I've got a 4TB HDD onto Bay1 and a Sonnet Tempo SSD Plus onto Slot 3. And the kryo m2/970Pro on Slot4. Could searching the boot drive for a while be the issue? And how to do better there?!

Forget fast boot time with a Mac Pro, even the MP6,1 one is slow to boot comparing with a recent MacBook Pro or nice PCs.

Mac Pro checks all the hardware with POST. Even if you strip the Mac Pro to the bare minimum, it will be slow to do the POST.

Think Mac Pro as a workstation/server, where reliability is more important than fast boot times.

fwiw, I boot in ~33 seconds; 14 seconds to the chime, 32-34 until I see the login window. I have two DT-120 cards, a velocity duo and a Vega64, W3690 and 24GB. No HDD or CD/DVD. Running 10.14.1.

You still get the chime? I haven't heard mine for a while (though I don't reboot that often). I'm on Mojave.

If you don’t have the chime, it’s a signal that something is wrong with the 1st and 2nd streams of your NVRAM volume. All correctly working Mac Pros with 140.0.0.0.0 and Mojave have the chime.

Go into System Preferences > Sound > Output (Tab) > Internal Speakers (Built-In) and make sure there is an output volume set (turn it up high). This has been muted on several machines I've seen recently and think may have accidentally happened during an update or reset.

That fixed it! Thankfully it was so easy. I've always used Windows in BIOS mode, so hopefully NVRAM corruption is unlikely.
