Man Thank you for your videos. I hope your channel grows a lot more. Please Please Pretty please make such videos for motherboards and for older motherboards if you can as well man. You can be our go too channel for motherboard information.
Thanks! I really appreciate your comment and I’m glad you found the videos useful. I’m hoping to cover all X870(E) PCIe lanes and then all physical boards. There are definitely some boards in the last gen of chipsets, of the 150+, that are worth going over. I’m curious what boards are you interested in? Trying to find the middle ground between useful accurate info and boringly over technical.. I hope I can deliver!
@@Ronin-Wilde Yes I've been watching your content for a bit now and love the way you do these videos. Literally no one else does this and it's so so so helpful. Older boards too would be great!
Thanks for sticking around I appreciate it! I'd like to do the older flagship boards and popular models. I was thinking of doing a VRM and USB breakdown in a similar format. Is this something you'd be interested in seeing? PCIe lanes, VRM, USB... I've noticed there is a lot of confusion out there around these main topics.
@@Ronin-Wilde Oh yes USB and VRM overviews would be great too. You're the only one that I have ever found that actually answers the questions, lays it out easily and displays it visually. Super easy to understand.
Finally a video that explains the layout of the PCI lanes on this board, been looking for this for a long time! Great video, thank you! Just to be sure, if i leave M.2_2 and PCIE2 empty PCIE1 will have all 16 lanes Gen 5.0.And last question: SATA connections don't take up any lanes?
I am glad it was helpful :) "if i leave M.2_2 and PCIE2 empty PCIE1 will have all 16 lanes Gen 5.0" Yes, if you leave these empty the x16 slot will have all 16 lanes available. SATA is incorporated in to the chipset, it will not impact CPU lanes. Here is a little more context if you are curious. Specifically SATA: The chipset has integrated SATA and I/O controllers. These controllers don't use lanes as physical copper traces like your CPU lanes, their "lanes" are built in to the chipset and run at Gen 3.0 speeds. Their bandwidth is managed by the chipset and connect to the CPU with the 4 lane chipset uplink. If a board manufacturer wants to add more SATA ports above and beyond what's available for the chipset spec. They would use physical lanes at Gen 3.0 from the chipset, to an additional SATA controller on the board. An example that comes to mind is the Asrock X870E Nova, it uses one of the Gen 3.0 chipset lanes to connect a SATA controller with 2 additional ports. Hope that helps.
Not sure if I understood this correctly but pcie5 x8 = pcie4 x 16 lanes wise. So if I occupied the m.2_2 slot then my motherboard will drop to pcie5 x8, but my gpu will still runs in pcie4 x16? Thanks for the help!
This would be the case if your GPU was Gen 5.0 compatible, if you have a Gen 4.0 GPU, it currently runs at Gen 4.0 x16 when all 16 lanes are available. In your example, the x16 slot will run at Gen 5.0 x8 mode. Like you said, that is a Gen 4.0 x16 equivalent for theoretical speeds. Because your GPU is Gen 4.0 compatible it can't use the 8 lanes at Gen 5.0. It will use those 8 lanes at Gen 4.0. The actual equivalent ends up being Gen 3.0 x16. Hopefully I explained that alright, let me know if you have any questions.
@@Ronin-Wilde Thank you great explanation. Kinda sucks a $500 motherboard has this bifurcation issue unless you buy Asrock 😔 I have a 7900xtx and planning on upgrading to the rtx 5090 in the future so I guess I cant use all 4 nvme
No problem, I'm glad it made sense :) The board manufacturers don't explain lane switching very well. It's a feature you pay more for, it's the only way to get more Gen 5.0 CPU lanes. Running those lanes increases board cost. Most gaming, production and lighter use cases don't use near the bandwidth of a Gen 3.0 x16 slot. I won't go on and on, but there is still value in 600 series boards. 800 series reduced overall CPU lane connectivity on most boards with the addition of USB4.
I would like to ask, will using a USB4 port have any impact on the graphics card's PCIe lanes? The diagram shows that USB4 is in copper color (PCIe 4), but is it using PCIe 5.0 lanes? I am considering purchasing this motherboard, so I would appreciate clarification on this matter. Thank you!
USB4 is completely separate from the graphics card and will have no impact on the x16 slot. USB4 has max transfer rate of 40 Gbps shared between two type c ports. 4 Gen 4.0 lanes is 64 Gbps, MSI doesn't mention Gen 5.0 lanes for USB4 and it wouldn't be necessary. They use 4 Gen 5.0 lanes on the tomahawk and those lanes are used by an M.2 and USB4, so there it makes sense. Hope that helps clarify, let me know if you have any questions.
So if I had 2x Gen 4.0 SSD's the best two slots to use would be M.2_1 and M.2_3 or M.2_1 and M.2_4? I ask as want to confirm what also is probably best thermal wise and does the first PROM 21 Chipset communicate faster than the second?
If you don’t want the x16 slot to run in x8 mode. You would use M.2_1 and M.2_3 or M.2_4. There would be a slight increase in latency when using slots connected to the second prom 21 chip. The data transfers to the first chip then to the second and back again. The 4 lane Gen 4 uplink, has 8GB/s of bandwidth in both directions to the CPU. If you are transferring large files, the transfer rate will be impacted by any devices using the chipset. For loading programs and games there is usually an initial spike in data transfer and then the transfer rate lowers.
There is a x16 slot direct to the CPU and a x16 slot to the chipset. I don't think a hyper m.2 is worth buying for this board. How many drives were you hoping to run in it?
I don't have any experience with AI development. For boards that have 2 Gen 5.0 M.2's before lane switching, which also have lane switching Gen 5.0 x8/x8 for your GPU's. The boards below offer this. X670E may be the better option if you must have all devices at Gen 5.0. X870E eats up 4 Gen 5.0 CPU lanes with USB4, X670E have those lanes available for your 2nd M.2. I'll see if I missed any boards, but these 4 come to mind. Edit: it looks like the X670E Carbon and Proart Creator are the most readily available.

Could you explain to me what slot I need to plug my GPU into if I'm buying a 5080 card or 5090? As I understsnd that those are the first gen 5 GPUs. I only want to use 2 m2 slots for SSD , where should I put those? Thanks and I'll sub because you seem very knowledgeable on this.
Thanks I appreciate it. You can use the first PCIe x16 slot for a Gen 5 GPU. You can put your boot ssd in M2_1. If you want a second Gen 5 ssd it would go in M2_2. Using that slot will drop the x16 slot to 8 lanes. Otherwise you can use M2_3 at Gen 4 through the chipset. That slot does not share lanes with the x16 slot. It shares lanes with the chipset uplink to the CPU.
@@eevd350z x8 is plenty of bandwidth for most things, gaming, video editing, lighter uses. You have paid extra for lane switching, if you benefit from the second m.2 drive speed, I’d leave it.
@@Ronin-Wilde I removed it but didn’t see any significant performance. I’ll just upgrade to larger m.2 to maybe 8tb for storage in that slot. Thanks for the videos sir. Your videos are excellent!
