What happened to the rest of the posts?
I think @CaseySJ removed them as we are going pretty much off topic. There are other threads for discussing those things.

Hi,
I'm about to mount a Gigabyte TITAN RIDGE add on card on my ASUS WS SAGE/10G and I'm wondering if this guide is the right one to flash my card? Should I use Raspberry Pi 4 or a flash programmer? Tx a lot
Yes, that is correct. The Raspberry Pi 3B or 4 (even the older Model 2) is suitable because they provide 3.3V outputs on the MISO (master in, slave out) and MOSI (master out, slave in) pins. The CH341A USB programmer sets them too high (5V).

Which posts?

My guess is that
1. Hamzab replies to your post quoting only the title (The end of Hackintosh as we know it)
2. Gandem doesn't like Hamzab's reply that only quotes the title. So asks Hamzab why he didn't include rest of the post(Reasonings and forecasts) in the quote.
3. Poddles replies,

Edit: Guessed wrong.

Also wondering if having 2 M.2 drives results in a decrease of bandwidth for each drive regardless of whether the other is in use. If so, I think I'd need to find a way of disabling in BIOS
I built a system like this as a transition to windows with a FW800 card for RME FF800, the first m2 is winboot, the 2nd m2 is storage and a there's an ssd for mac boot and a SATA pci card for more drives. Bandwidth and CPU power seem totally rocking. There's dual boot notes at the beginning of this thread. Hopefully you'll have better luck then me with USB freezes in osx- they seem to effect some systems and not others and its a puzzle why. Windows is rock solid. I formatted most of my storage as exfat and this might have been a bit of mistake because if you have to reset a USB frozen osx it can temporarily corrupt the drives. Windows will remount them, OSX might not. Basically I'm making the full transition to windows sooner then anticipated and will go with NTFS for all my internal drives and the paragon NTFS to access them in OSX if need be and an a HFS+ ssd with my last round of OSX projects on it. The main function of the mac drive for me is to open previous work. I'm also using paragon HFS+ on the win side and recently had a couple HFS+ drives get wonky (read errors- Mac disk utilities can't fix). This happened with the addition of a new sata PCI (first one didnt work properly) card so I'm not sure whats to blame. Luckily I have great backups but from my month or so experience dual booting is not looking good as a viable long term solution. Maybe others who dual boot can chime in on what drive formats they use. I've learned a lot and I'm glad to have the ability to open old mac based projects but its been a lot more complicated then I thought it would be.

Both M.2 slots are connected by four lanes to the chipset, which in turn has four lanes to the CPU. Unless you're hammering both SSDs simultaneously (which is unlikely if you've got separate OS installs on each) then you won't see any noticeable performance degradation.

If you had external SSDs and a 10GbE NIC connected to your Thunderbolt 3 ports (also connected to chipset) processing a heavy workload and were also working your M.2 SSD hard, then you'd probably notice a difference.

Even so, it's not something I would fret about. If you really want to not worry about PCI-E lanes, you really should be buying an HEDT platform like Intel X-series or Threadripper.

But then we'd find windows writing files on the osx partition, unless you put win first, and install it first. That is my understanding at least. Interestingly I am also using a fireface, this is why I picked the designare z390 with integrated Bluetooth 3. I also have a motu PCIe424 and one worry of mine is running 2x M2 ssd's through PCH and the associated bandwidth restriction to my PCI cards - 3 x PCIEx1 cards

M2 drives, PCI lanes and SATA ports.

Hi there. So, I am planning a dual boot Hack along the lines of this build and had a question about M2 drives. I've been delving through the gigabyte forums but everyone seems to have a different opinion. If I run Win in the top M2 and OSX in the bottom (both PCI SSD's) I lose SATA ports 0, 4 and 5. This I can handle. With PCIx4 set to PCH the GPU still has the full 16 lanes but I'm trying to figure out what I have left for PCI cards. Is it just 4 lanes shared across the x8, x4, two x1's and the M2's. As the M2's are each different OS they'll only be running one at a time so not so much of a bandwidth issue but I wonder if there are still knock ons to do with addressing.

Basically I need to be confident that I can get away with 2x PCI M2's, Fenvi wifi, MOTU PCIe424 (connected to 2 x 24IO boards), Genenric Firewire 400/800 card connected to Fireface 400. They're all x1 cards and the MOTU won't be running at the same time as the fireface. If the TB3 > 2 > 1 conversion works I can scrap the generic firewire card. Don't want to bank on that though. In terms of what will be operational at any given time I think 3 lanes to the active M2 would allow full speed operation but that leaves 1 lane shared across audio, FW and wifi/bluetooth. Having written all this down it doesn't seem like a lot, I've crammed a lot more into a board before but NVME is new to me and I don't want to shoot myself in the foot before I begin.

Many thanks,

Jim
Good questions:
  • The three long slots are physically x16, x8, and x4.
  • But there are only 16 PCIe lanes from those slots to the CPU.
  • So the 3 long slots operate like this:
    • If only Slot 1 is used, it operates in x16
    • If only Slot 2 is used, it operates in x8
    • If Slots 1 and 2 are used, each operates in x8 (for total of 16 lanes)
    • If Slots 1, 2, and 3 are all used, they operate in x8, x4, x4 (for total of 16 lanes; see screenshot below)
    • But if Slot 3 is routed to PCH via BIOS (PCIE x4 Switch below), then the 3 slots operate in x8, x8, x4 (16 lanes from CPU, 4 lanes from PCH)
  • The x1 slots are routed to PCH.
  • The two M.2 slots are always running at x4 each, also routed to PCH.
