PCIe 1 to 4 Riser Card, Pcie Splitter 1 to 4 PCI Riser Card, 4 Risers into 1 PCI Card, PCIe Multiplier Risers 1X to External 4 PCI-e USB3.0 Adapter for ETH Miner GPU Crypto Bitcoin Ethereum Mining Rig

Product Information

Picture shown is riser with 2-slots PCIe X8 which can be configured up to 3-slots independent expansions( 3-slots PCIe, 2-slots PCIe + 1-slot PCI/PCIX or 1-slot PCIe + 2-slots PCI-X independent). The top riser slot sit to the board slot6 which aligns to the horizontal three-slots cutout of the 2U chassis, the middle and bottom slots are connected with various lengths of ribbon cable to reach different position of board slots.

PCI-E 6 Pin to Dual 8(6+2) Pin Splitter Power Cable, 6 Pin

I have a single PCIe 3 x16 slot currently occupied by an LSI 9311-8i HBA. The HBA takes 8 lanes, and I'd like to see whether I can somehow have a splitter card (if that's something that exists, or if that's the correct name for it) that can occupy a full PCIe x16 slot, but expose two additional x8 slots. One of the smaller slots should accept the HBA, while the other one - maybe a PCIe x8 to two M.2 NVMe slots adapter? So that I can use a couple of NVMe SSDs for ZIL/SLOG or a dedicated pool for Git repos.

Before deciding to add more PCIe slots to your computer, you should consider the purpose of your computer and what devices you plan to use with the additional slots.

you're missing the problem of the actual splitter needing to support sli which it will definitely not

The scariest thing about Apple’s announcement

With splitters from m.2 to x4 PCIe then x4 to x16 PCIe splitter, I'm curious if with some BIOS tweak or DifferentSLIAuto will allow for enough bandwidth for the system to run SLI. But like I said above NVIDIA requires x8 for SLI You can't just add bandwidth. The max you will get out of any devices connected to an M.2 port is 4x. That's the PHYSICAL limit of that port at the moment. The first option is expensive and may not be viable if you already have a running system. Motherboards typically come with a fixed number of PCIe slots, which cannot be changed outside of getting a new board. you effectively have to add another pci-e controller to the machine and the controller has to support sli.

split a 8pin PCIe into 2 8pin PCIe? - [H]ard|Forum is it safe to split a 8pin PCIe into 2 8pin PCIe? - [H]ard|Forum

I think where most people get into trouble is when they start using SATA power cables to power either risers or GPU's directly, especially if they do more than 2 connections per SATA "string". On the other hand, if the four connected devices have a lower bandwidth demand than 1 GB/s, they should work fine. Some common mistakes to avoid include not properly grounding yourself before handling hardware, using too much force when installing PCIe cards, not properly securing PCIe cards in their slots, and not properly connecting power cables to the new hardware.I’m thinking switching the splitter to a full size PCIE-16 will fix the problem but haven’t tried it yet.

How to Add More PCIe Slots? - PC Guide 101

Take the splitter above, for instance. So here, basically, an x4 host card splits into 4 x PCIe x16 slots. If each splitter is occupied, each connected device will be subject to the overall bandwidth provided by the x4 host slot. This splitter connects to x1 slot on the board and then splits into four x1 slots for further expansion. So basically, the idea here is that the amount of bandwidth the cards occupy on the splitters should not be greater than the bandwidth provided by the primary x1 host slot connected to the motherboard. I've seen products that allow people to split the pci slots into their seperate channels. They appear to be purely mechanical devices. The wires aren't the problem, it's the pins. SATA is rated for 1.5a per pin, so 3 x 12v = 54w (PCIe max slot power is 75w). Per pin amperage for a 4-pin Molex is 8.5a, so you can get 102w from it's +12v pin. I've seen both 11a and 13a for PCIe pins so 3x 12v = 396-468wThank you all for your recommendations. Indeed, simply replacing the motherboard would be the cheapest solution for this use case. However: Having more PCIe slots means getting the opportunity to install more expansion cards for various uses. However, there are only two ways to increase the amount of PCIe slots you have: You might be able to get around it with differentsliauto, but there is no guarantee that will continue to work.. Z370N-Wifi from Gigabyte supports Bifurcation. so with a Riser and DifferentSLIAuto it seems possible The Flexible x4 PCI Express 4-Way Splitter was designed to expand your modern motherboard (ATX, mini ATX, etc.) with a limited number of PCI Express connectors. It allows you to connect up to four x1 / x4 / x16 PCI Express boards to your motherboard’s x4/x8/x16 PCI Express connector.
