Posted July 5, 2021 Hi, so Ryzen 7 5800x and a strix x570-f motherboard. Please help me here. Can I use the full x16 4.0 slot for the gpu and the x4 4.0 m.2 slot AND the second 4x 4.0 m.2 slot + 4 sata 6gb/s devices without running into any of this stuff sharing lanes? Cpu lanes should be 16x gpu, 4x m.2 slot and 4x down to the chipset. If the second m.2 slot alone needs 4x 4.0 pcie lanes already.. then this doesn't really work, right? Or does it? My head is exploding xD And does anyone know if direct storage will need the ssd to be installed into the slot with the cpu lanes? Just curious. Edit. HurrDurr just found out that taking a closer look into the manual is indeed - quite helpfull https://dlcdnets.asus.com/pub/ASUS/mb/SocketAM4/ROG_STRIX_X570-F_GAMING/E15827_ROG_STRIX_X570-F_GAMING_UM_v2_WEB.pdf Pcie operating mode: Chapter 1, site 1-7. Says that it should be fine. Nothing to be found on the sata ports tho. I thought that could cause a problem. Link to comment Share on other sites More sharing options...

Posted July 5, 2021 Yeah. The key is bandwidth. Yes, a lot of what you mentioned is going to be sharing the 4 lanes going into the chipset, but you're not going to be saturating those lanes in most cases. For example, the 4 SATA drives is barely a blip on a single PCIe 4.0 lane.

I thought that could cause a problem. Small bandwidth sharing between the second m.2 drive (because of chipset bandwidth) but it would not be noticably affecting performance I WILL find your ITX build thread, and I WILL recommend the SIlverstone Sugo SG13B Primary PC: i7 8086k - EVGA Z370 Classified K - G.Skill Trident Z RGB - WD SN750 - Jedi Order Titan Xp - Hyper 212 Black (with RGB Riing flair) - EVGA G3 650W - dual booting Windows 10 and Linux - Black and green theme, Razer brainwashed me.

Posted July 5, 2021 Author Alright thanks for the info! So if there is some sharing happening, I will move the system ssd into the bottom slot and be prepared to get a gen 4 m.2 ssd whenever direct storage comes around.
