I'm a little stumped on why my pcie card isn't running at 4x width. I have installed a pcie 3.0 4x adapter and run pcitools to enable 2.0 and 5 GT/s on slot 2 but no matter what I do my 3,1 only shows a link width of 2x. I'm running High Sierra installed using dosdude1's patch and I'm booting from the nvme. My SSD should be getting 1550/800mb but I'm only getting 650/750 read/write. Any ideas on what I can do to enable link width of 4x?
The SSD is an Inland Professional 256gb (1550/800mb)
PCIe card is a Micro Connectors PCIE-M20803HS (M Key)

Option 3 should be the best throughput, wouldn't it...? x16, x1, x1, x8.
I guess the question is can the board be triggered into that mode with a x8 switch card rather than a kicker GPU?
Misunderstood their wonderful transitions.

I think that is only for Mac Pro till 3.1, where the lanes are configurable.
What can I say, I'm a dreamer. I missed that fixed/dynamic part and had thought all these boards had dynamic lanes, but hadn't even used anything but a GPU in mine.

Not quite true. The PCIe lanes are not configurable in the cMP 3,1, but they are the the cMP 1,1 and 2,1.

thanks I didn't noticed that I will fix that picture, ASAPMight want to blurr your packing list, G-Blue
the problem is that I'm using windows because I'm waiting for web drivers
but I will login to my Mojave drive and fix the picture
I'm also waiting for high point SSD7102 drivers and app for mac os
can only make a raid volume using disk utility because I don't have high point app for mac os
but the app also needs the drivers without the kext driver the app won't recognized the cards
that's why I'm running windows for now
I do hate windows for many reasons
but i discovered a new reason, windows has a 2 gb speed limit in copy paste operations that mac os doesn't have
so my 21 GBPS reading and 19 GBPS writing speed are totally useless on windows

You can't blame Microsoft for a failure to use tools to blur an image. The tools exist on Windows, your ignorance of them is not MSFT's fault.
I already fixed the picture using windows
I have used windows all my life until windows 8 came out
then I stopped liking windows and when w10 came out then I started hating windows
I'm only using it now because I need to do some work that I can't do in Mojave because I don't have web drivers for Mojave and I have a NVidia card because I don't like AMD
it was actually very simple to do it from windows
but I'm use to using mac preview app
but I didn't had to login to my Mojave drive either
you misunderstood the comment and twisted around
is not ignorance like you mentioned
the app was updated so is different, is not the same way it used to be
and I haven't use that app in a long time
but even that Microsoft made changes to the app, I was able to find the option and figure out how to do it quick
thanks

We've all been in awkward situations, G-Blue . . .
. . . there's no shame in not knowing everything, nor is there shame in not knowing just a few things.
A man I know once shared with me:
"Ignorance is doing something once; Stupidity is doing it twice."
I look forward to your experience in how you drive these two x16 cards to new heights . . . hopefully in the HighPoint Thread

Hi Lou,
Regarding your setup, 3 questions:
1) Can I mix a SM951 AHCI 512GB as a system boot drive and a 1TB 970 PRO NVMe as a data/storage drive in the same I/O Crest card? I see below that you mention they can be mixed, but not sure if this works as a non-RAID, boot/storage combination.
2) What speeds can I expect from each independent drive if placed in: A) Slot 3 (x4), B) Slot 2 (x16)?
3) Is the I/O Crest SI_PEX40129 the correct model number? I've included Amazon link below.

Many thanks in advance!

1. Yes. Don't know about RAID. Assume you can.
2. I've run mine only in slot 2. AJA speed is:
SM951 AHCI In PX1 in slot 4 is:
3. Yes that is the correct card. I bought mine from Alibaba in China.

Hi Lou,
As seen in your submitted Aja benchmark, do you "Feel" a real-world difference when you compare your two boot SSD's ?
How big is the speed difference in your everyday application? Can you recognize it, - like oh, now I am finally back on Mojave with the fast SSD when you boot up. I am curious about your experience.
The Crest card for me was mainly for saving a full slot, not so much about speed. At the moment I even boot Mojave from my old HyperXPredtor 941 AHCI 960 with about 870 - 920 MB/sec. Not the fastest, - but I don't want to block my Vega64 fan.
My SM951 AHCI, of course, is faster but a lot smaller and the 970EVO 2TB is on order an has not arrived yet. For me, somehow it feels that Mojave really runs a lot faster than High Sierra with the AHCI blades, - don't ask me why.

^^^^I'm still on HS because of my Nvidia GPU
Do I notice a real world difference between the SM951 and the 970 Pro. Not really though some large Excel spread sheets open faster, as do some JPEGs in PS. It should be noted that boot time is longer with the NVMe over the AHCI.

Thanks much for the details and benchmarks!
[doublepost=1547417888][/doublepost]Same reason here, to free up a PCIe slot more so than higher throughput. Game changer to have 2 independent M.2 cards in 1 PCIe slot!
What "pcitools" let you enable PCIe 2.0 and 5GT/s on slot 2 with an x4 card?
EDIT: I've figured out how to use pciutils to enable 2.0 and 5GT/s in the x16 slot, but every time I shut down/restart I have to perform the process all over again. Is there any way to make this change permanent?

Given cheap PCIe adapters don't include PLX switches etc, I understand that when using a PCIe 4x SSD, the maximum bandwidth will be 1500MB/s in a cMP. Could anyone let me know the following:
- Should one just buy the cheapest PCIe adapter, since there are ~no active components? Does anyone have any suggestions for proven models?
- Is there a boot delay with NVMe? If so, how long?
- Is there a boot delay with AHCI PCIe M.2 devices?
- Although the peak bandwidth with large files won't exceed 1500MB/s, presumably the best SSDs are still faster than older / cheaper ones for 4K reads (which are more relevant anyway)? Would you recommend the modern default choice of a WD Black / Samsung 970 EVO, or could bargains be found with older, secondhand NVMe drives? Has anyone upgraded from one to the other?
- I've read mixed things about using a PCIe drive as a boot drive, whether Mac or PC. Many seem to say the difference isn't noticeable from SATA (even SATA II) in practice; others notice a big difference. Would using one make launching, say, Adobe CC or MS Office apps any faster? I'm currently using an 850 EVO in a SATA II bay.
If I got an NVMe drive, I'd keep using the 850 for stuff like my photo library, and for Bootcamp.

Angelbird Wings PX1 is great. Includes the heatsink, tools, and included directions are actually useful and easy to follow for a change. Using it with EVO 970 right now. MANY of the cheaper adapters do not include heatsink, which ultimately raises their price. Just double-check whichever you choose.
Depends on the Adobe CC app. I've noticed faster AE CC 2019, PPro CC 2019, and Media Encoder CC 2019 starts, but those apps use a lot of plugins. Audition CC 2019 opens almost instantly. Other apps (like Photoshop CC 2019 and Illustrator CC 2019) are negligible start difference compared to previous setup (SATA SSD via PCIe adapter for system drive).
Keep ALL ADOBE LIBRARIES on a different drive and you'll speed up start times.
IMO.. This is a much better option than the Anglebird for $129. It should be compatible with the 4,1/5,1.
This card has PCIe 2.0 switch, no? So same 1500MB/s limit.
It's better to buy the IOCrest one from Alibaba for around $180.
I was comparing it to the $99 Anglebird Wings. For $30 more, you get 2 M.2 slots that can run at 1550 MB/s in PCIe slot 3 or 4.
