Hi [NAME].mknabster , I can confirmed the T5810 does support bifurcation natively.  It would recognize up to four NVME cards automatically.  I don't know about the adapter you are looking at but if you check some of my recent posts on the same topic, I provided some links to similar adapters and you can check the reviews on those and decide which one to get. You listed the slot numbering backward from the imprints on motherboard so it take a while for me to understand your current setup.  Here is my thought, if you are using PCIe gen 2 slot, it will reduce the speed in half.  Keep in mind that the NVME will produce lot of heat and if they are over 70 or 80 degree, it will throttle the transfer speed.  So, get the adapter with cooling features (heatsink, fan).  Good luck with your project.
Hi all, I'm looking to replace my spinning 1TB disk with 2x 1TB NVMe sticks i have accumulated from past laptops, and put it into my Precision 5810 to use purely for storage. I was planning on setting them up as RAID 0 with software RAID. I found a card on ebay that referenced something called PCIe bifurcation or splitting, and they said to make sure my motherboard supported x4x4x4x4 on my x16 slot. Here's a link to the one i'm looking at: [URL] As i look in my tower (i'm going form the bottom up as in this listing: [URL] i currently have PCI slot 1 for my sound card, PCIe slot 2 and 3 are free, slot 4 is covered by my graphics card in slot 5, and PCIe slot 6 has my NIC in it. I had read in other posts that the 5810 should work with these types of cards, but i wanted to verify which slot i should plug it into. I'm guessing my remaining PCIe 3.0 x16 slot would be perfect, but i hate that it's so close to the GPU, I would prefer it to be in this one: PCIe x16 slot (PCIe 2.0 wired as x4) though it doesn't sound like that would work properly. Am i right or wrong in my thinking? Any advice or thoughts would be appreciated. Thanks!
PCIe Slot Splitting in 5810?
