I want to buy a new M.2. Samsung 950 Pro (256GB model). But my motherboard is a MSI GUARD-PRO ATX with 2 PCIe x16 slots. One being the video card obviously.
• CPU: Intel® Core™ i7-4790 3.60 GHz 8MB LGA1150
• HDD: (2) 3TB SATA-III 6.0Gb/s 64MB Cache 7200RPM
• SSD: 256GB ADATA SP600
• SSD: 512GB MX100
• HDD: 250 GB
• MEMORY: 16GB DDR3/1866MHz Dual Channel Memory (Corsair Vengeance)
• MOTHERBOARD: MSI GUARD-PRO ATX w/GbLAN, 2 PCIe x16, 4 PCIe x1, 3 PCI, 1 x M.2, 6x SATA 6Gb/s
• OS: Microsoft® Windows 8.1 (64-bit Edition)
o Soon to be Microsoft® Windows 10 (64-bit Edition)
• VIDEO CARD: AMD Radeon R9 270 2GB GDDR5 PCIe 3.0 x16
o Soon to be a GTX 980ti
The M.2. Samsung 950 Pro needs a PCI-e Gen 3 x4. I only have the 2.0 x16 which correct me if I am wrong I can get an adapter for. (To be honest I am not sure my Motherboard can run the x16 at x8 (I think it can run at X4) but even if it can I hear that it will effect my graphics card a bit. This might be a huge problem for me depending on the amount. Does anyone know if it affects your GPU and if so how much? And if the 950 Pro will be affected? So if I do plug it into my other x16 slot, will my GPU go down to x8 performance? I realize there's not huge performance drop between x8 and x16 for GPU, but am curious if that is the case or if I can get x4 on one slot and x16 on the other?
It will indeed reduce the video card to PCIe 3.0 x8 and I think its possible to make it a 2.0 x4 (as shown below from MSI website) would that slow my 950 Pro down and cause me to lose my 4 x1 slots bc I have an Ethernet card in one. The rest I don’t care.
• 1 x PCIe 3.0 x16 slot (PCI_E2, supports x16 speed)
• 1 x PCIe 2.0 x16 slot (PCI_E4, supports x4 speed)
• 4 x PCIe 2.0 x1 slots
Thank you for any help.
