I have an i5 6600k with a GTX 970 both installed in an Asus Z170-P D3. The GTX 970 is installed in the top grey PCIE x16 3.0 slot. My question is if I get an M.2 NVME SSD drive will it take up any of my lanes, dropping my GTX 970 to run at x8, or does Z170 or my i5 6600k have 4 PCIE lanes dedicated to to the M.2 drive?

Finally finished building my PC with the last touch. Just waiting for my other 16GB ram stick to arrive next week.

Hi, I'm a bit confused about how cpu and chipset pcie lanes works on a motherboard and how to address possible configurations for high performace system builds. I've read around but it seems to me like there is a lot of confusion on the argument. I understood that every cpu has a total number of pcie lanes available/supported and the motherboard manufactures decides how to handle them for different configurations. As far as I know the DMI act as a pcie bottleneck merging all the pcie lanes from the chipset to x4 lanes (please correct me if I'm wrong). So the question is, how do I know exaclty how the pcie slots are configured in a motherboard, wich slots are directly connected to the cpu and wich slots goes through the DMI? I've never seen something related to that in the manuals. Skylake-x processors has up to 44 pcie lanes with x299 chipset, and assuming that the x16 slots are directly connected to the cpu, can I use one of these to connect a firewire x1 expansion card (or a usb 3 expansion card, or thunderbolt 3) to connect my external audio interface directly to the cpu instead of using the regular i/o on the motherboard that is bottlenecked by the DMI? Is this something that make sense? thanks in advance patrick -
Hey, at first I bought an MSI b450 motherboard and a ryzen 5 2400g with intent to upgrade. I now have it paired up with a 1070 Ti and I'm waiting for 3rd gen ryzen. I have a 120gb sata ssd for my boot drive and a 1tb hdd for the other stuff but I've seen quite good deals on a 1tb intel 660p which is an NVMe drive but I don't know if I have enough dedicated pci-e lanes with this cpu ? I saw that my cpu has 12 pci-e lanes, 8 for gpu and 4 for NVMe drives but I have my gpu in a x16 slot, does it take up all my pci-e lanes and will my motherboard recognize the drive or should I get a new cpu first ? Thanks.

I red a lot about this and have not yet come to a final conclusion. My motherboard is a Gigabyte z270 k3, with a i5 7600k. I bought and addlink s70 pcie 3.0 x4 240gb nvme ssd. From what I know installing that drive wont change my gpu connection speed (16x) because the m2 port on my mobo is configured to use chipset lanes. I already have 2 hdd on raid 0 and 2 sata ssds for storage on the same motherboard. Will the performance of the rest of the drives or the connection of the gpu (msi r390 8gb right now might change it later) be affected in any way?

Hello, what is PCIE lanes supported by intel chipset? amd does it affect gaming performance? my b360 supports only 12 lanes, i have 9700 paired with 5700xt!

x299 boards have always been marketed as supporting up to 44 PCIe lanes, but the latest i9-10___X series processors have 48 PCIe lanes. It's great that legacy X299 boards now have a BIOS update to support the latest 10th gen processors (BIOS v 2002 for ASUS Prime Deluxe), however no one speaks to whether they will accommodate all 48 lanes... Can the motherboard take advantage of these extra lanes available on the CPU? Or is it hardwired to only support up to 44? Finally, if the extra 4 lanes cannot be utilized, does anyone have the expertise to know if this would affect iommu groupings for something such as unraid? If 4 CPU PCIe lanes are disabled/ignored, this should not cause any issues when carrying out hardware pass-through to virtual machines right? There's already plenty of documentation on manuals indicating the consequences of inserting a lower lane CPU into an X299 board (e.g. 28 or 16-lane CPU) which results in PCIe slots being disabled e.g. m.2/u.2 lane sharing with other physical PCIe slots. I believe the chipset lanes will remained unchanged at 24 or so, and I'm not interested in purchasing an expensive X299X MB, so I feel this information is worth knowing for HEDT enthusiasts! -
My parts arrive next week. i5-8500 and Gtx 1080 on A Gigabyte H310M S2H. Now I also ordered one of them pcie 4x USB 3.0 cards. Also, I'm dumb when it comes to lanes. I know to things so far - my CPU supports 16 lanes and that guy can run both 8 and 16. What does this mean for my rig? If some one could take the time to explain lanes effects to me, i would appreciateb that a lot! TY

Hey folks, i wondered if you could help me with a bit of trouble shooting. First, this is my rig: OS: Windows 10 Pro 64 bit CPU: Intel i9-7900X RAM: 32 GB DDR4 3600 MHz Corsair Dominator Platinum MB: ASUS TUF x299 Mark 1 GPU: Gigabyte GTX Titan X Drives: Samsung SSD 840 EVO 120 GB; Samsung SSD 840 EVO 1 TB; Samsung M.2 SSD 970 EVO 1 TB; WD HDD 2 TB PSU: BeQuiet Dark Power Pro 11 1200 Watts So here's the problem: Even though i switched out my motherboard, memory and CPU my second GTX Titan X is still running only at 8 PCIe 3.0 lanes instead of 16. My previous build was the i7-5930K, an MSI X99s Krait Edition Motherboard and Kingston Hyper X Fury 2133 MHz RAM. Both builds had more than enough PCIe 3.0 Lanes available and i remember when i first assembled the system both GPUs ran on 16x but i don't know when it stopped. So in summary i changed the Motherboard twice (once for testing), i switched the memory and CPU and switched the Slots for the GPUs and even tried the one that's causing problems in single mode in the same slot the other GPU runs on 16 lanes. I never reached 16 lanes on that card again. For some reason the two cards have different BIOSes but i don't think that this causes the problem. Thanks in advance for your help.

Hey guys, Quick question, I'm a bit confused about available PCIE lanes with a certain configuration: I want to run a i9 9900k, which has a maximum of 16 PCIE lanes on a Gigabyte Z390 Motherboard. I read somewhere that the chipset provides another few PCIE lanes? So say I use up the 16x PCIE lanes with my graphics card, will I be able to install 2x m.2 SSD's? Or do i have too few PCIE lanes? Thanks for the help in advance, I just need a bit of reassurance before actually ordering the parts.

I'm sure everyone here has seen the ads and Amazon listing for the i9-9900k processor, and maybe a few of you already have it. If so, you've probably noticed the claim that the new chip has "up to 40 platform PCIe lanes." I jumped at that because my blasted i7-7700T on a Z270 MB can't cope with dual M.2 SSDs AND a 1080 Ti. This results in an obvious bottleneck. The claim to 40 lanes had me excited because a mainstream processor would finally be able to cope with my workload...then I looked at Intel's site. On their listing as well as on their "Ark" product index site, the processor is said to only have 16 PCIe lanes. This obviously wouldn't be any better than my current processor (besides the boost in performance from overclocking, better Turbo Boost, newer platform, etc.) for coping with my workload. Does anyone have the real number of lanes, or can explain the difference in numbers? I don't want to drop $530 on a CPU before knowing whether or not this is gonna fix my problem.

~ Topic Introduction ~ Quite recently, I've been running into a few audio issues, and it's been bothering me. Probably doesn't help I use 2 sound systems for the same audio stream, but regardless. I've been interested in buying a PCIe x1 sound card to fix some of those issues, and have a bit more flexibility in general, like actually having a TOSLINK-in port. But the main thing I'm wondering about, is how many "lanes" am I using on my CPU currently? I'm not a computer genius, so I'm not sure. ~ Currently Installed Parts ~ I've been called 'strange' for the parts I use, but here's some of them, in which I would assume uses PCIe lanes. - MSI GeForce GTX 1070 Aero GB OC (PCIe 3.0 x16) - AverMedia Live Gamer Lite HD (PCIe 3.0 x1) - Samsung 960 EVO NVMe SSD (M.2) - Western Digital M.2 SATA SSD (M.2) - X299 Chipset From what I heard, Samsung's 960 EVO and PRO series NVMe SSD runs on a PCIe 3.0 x4 interface through the M.2 slot, if I'm not mistaken. I'd assume I use 21 PCIe lanes or something, but I can't tell for sure. Kind of feel like an idiot for thinking I use that much, but I honestly have no idea. ;w; ~ Comments ~ So I'm asking you, the community. How many PCIe lanes am I using? Because, again, I have no idea. Realizing I may or may not sound like an idiot for posting this, I felt like asking regardless. If anyone has an idea, or even know, please inform me. ~ Recap ~ Please don't approach me with a wall of text just because this post is related to a sound card, in 2018. >-< I'm mostly concerned about my PCIe lane usage, based off from what I currently use. Thanks in advance for those who understand. ^^;

I can't find anything on this so I wanted to know more a bout how PCIe lanes work. My cpu has 24 lanes supported, 4 are taken for other tasks so that leaves 20 open. x16 4.0 for the graphics card and x4 3.0 for a capture card. Is the 3.0 and 4.0 interface considered separate from each other? Or do they both take up the same lane? The motherboard I'm getting soon has a 4.0 and 3.0 m.2 slot and I wanted to get one but I as you would expect I don't want my graphics card to go down to x8 just for the m.2. How do all the parts interact with the different versions of PCIe if that is the case? Parts for ref: X570 Crosshair VIII Hero Mobo RTX 3080 Elgato 4k60 Any 4.0/3.0 m.2 that I find. Thanks!
-
Dual gpu card setup is x8, but if you disable one of the cards does the pcie x16 slot run full speed? reason is I am going to get the 30 series but I run hackintosh so I want l the 3080 series, and my Vega 56 both in it. And the only CPUs that run 100% no prob that I know is intel coffee lake. So please don’t tell me get a cpu with more pcie lanes the 9900k is as good as it gets for my usage.

First of all, my hardware specs: Asus ROG Maximus X Hero (WiFi/AC) 4x8GB HyperX Fury 2.400MHz i7-8700k (may be upgraded to 8086k) 960pro NVMe SSD (512GB) Optane 900p (280GB) MSI 1080ti Gaming X 11G Disclaimer: I'm somewhat unexperienced in regards to lanes, speeds, and bottlenecks. Please feel free to correct everything. AFIAK, for full bandwidth, both, the optane and 960pro need x4, the 1080ti needs at least x8 (x16, but x8 shouldn't be a bottleneck) and I think my Z370 also needs up to x4 for my SATA/USB3 devices. That's definitely more than the available 16 lanes with both the 8700k and 8086k. So my question is: would I experience any kind of bottleneck due to the lack of PCIe lanes, when everything is plugged in, and is ist worth upgrading to an i9? Mainly, I'm using this RIG for gaming and hosting "software"-servers like TS3/ARK/MC/etc., but I don't wanna "feel" any bottlenecks. So if upgrading to 28 or even 44 lanes would cause my system to boot like 2% faster, idc. But I definetely don't want stuttering in-game or server-lags because my NVMe drive has to few dedicated lanes. Thanks in advance for any advice.

Hi. I suppose to deal with my college assignment but someone asked me this question. What is HSIO lanes and how are they related to PCIe Lanes? So i explained to him everything i know about it but it wasn't clear enough for him to fully understand it because i ended up getting confused as well. Of course i already read everything from google but i still didn't fully understand it. So for example, Z270 has total of 24 Pcie Lanes and 30 Hsio lanes (Six of which is already consumed by permanently enabled 6 USB 3.0 *See picture below) Ok so from what i understand, If i already use 16 of total available 24 lanes for the Graphic card i ended up with only 8 available Pcie lanes right? So what if i decided to use only one USB (e.g USB 3.0 #7) from HSIO lanes 7-10 will it cut the number of my Pcie lanes into 7? Even though i only use One HSIO lanes? If so, What if i only use 1 Lan card in the HSIO lanes number 10? will it also cut my lanes into 7 or what? I am really confuse here help

my laptop allows for 2 m.2 ssds to be installed, however i believe it only has 4 pice lanes available, if i install 2 nvme m.2s will they both simply use 2 lanes each or will it not work at all? sorry this is the first time i will be installing an m.2 and im just trying to understand better beofre i sink over 250$ into something...

Hey guys i have a question that i wonder about since some tim but i cant figure anything out via googeling it. So i have a 1700X on a x370 mobo (Gigabyte x370 Gaming K5) and i want to buy a sound card for my 7.1 Sound system. Ryzen sys that it has 24 lanes in total. So when i throw in that x4 sound card in the top PCIe slot willt bring my GTX 1080ti down to x8 speed?? Thanks

Hi everyone. I want to build a new pc. I am pretty sure I know what I want but need two big questions I have answered. Here is a link to pcpartpicker for the build I have in mind. https://pcpartpicker.com/list/n2Tqq4 now my two questions are first since the i7 8700k has 16 lanes if I added a graphics card would my m.2 be bottlenecked or my graphics cards since it’s sharing the same 16lanes? Also can I stream to twitch without a graphics card if I’m capturing the gameplay from Xbox? I want to hold off on buying a graphics card until prices go down

Hi everyone, I have a Pentium g4560 CPU on an Asus Prime z270-a motherboard. I have a 1060 and a 1070 in full slots. I know for a fact that both are functional. However, when I open device manager, display interfaces, the 1060 doesn't show up. My miner isn't detecting the 1060 either. This could be a problem with PCIe lanes. The Pentium only has 16, and each GPU would theoretically take up 16, making 32 which is too much. However, the board is capable of using x8 instead of x16, so I am very confused why the 1060 isn't detected. Any help is appreciated! Thanks!

So my CPU (i7-4790k) gives 16 lanes and my mobo (ASRock H97M PRO4) offers 1 PCIe 3.0 x16, 1 PCIe 2.0 x16, 2 PCI. My 1080 ti takes up 16 lanes of the PCIe 3.0. Would adding a Thunderbolt 2 AIC which takes up PCIe 2.0 x4 effect the performance of my 1080 ti with its PCIe 3.0 x16? If so, how much of an impact would it have? What if it was Thunderbolt 3 AIC which uses PCIe 3.0 x4? I'm not sure which category this question belongs in, so apologies in advance if I placed it in the wrong one. -
Hey Peoples! I have an old gtx 780 from Zotac from a Friend (for free) and i just saw that there is something broken off (see picture) Can someone tell me what this is and will it harm my PC if i put it in? He gave it to me instead of throwing it away, i wanted to use it for mining. Thanks in advance Cheers

Alright so I thought I knew how pci lanes worked and it just keeps proving to me that I don't. I'm getting an 8700k on the Asus Prime Z370-A ATX LGA 1151 motherboard. The 8700k has 16 pci lanes, I know that, and I know that my graphics card will use 16. I had heard that the chipset can provide some but I have no idea how many this motherboard does. I looked online at the specs and it doesn't say how many lanes the specific board has. The intel website says the max number of lanes is 24, but does that mean that I'll have 24 lanes or what? So that, and then one last thing. I want to have the gpu, an m.2, and one additional pci x4/x1 card (specifically the elgato hd60 pro). Will that work with how the setup is or no?

Hi, I have a quick question. Amd Ryzen with am4 support 24 lanes. For exemple, GIGABYTE GA-AX370-Gaming (rev. 1.0) uses 16 lanes for pci-express x16 3.0 and shares 4 lanes between pci-express 2.0 x16 and pci-express x1 slot 2 and 3. From gigabyte description : The PCIEX4 slot shares bandwidth with the PCIEX1_2 and PCIEX1_3 slots. The PCIEX4 slot operates at up to x2 mode when the PCIEX1_2/PCIEX1_3 slot is populated. The PCIEX4 slot operates at up to x4 mode when both of the PCIEX1_2 and PCIEX1_3 slots are empty. And finally 4 lanes for the m.2. However, The pci-express x1 slot 1 doesn't shares any lanes with the slot 2 and 3. Does it shares his lanes with the m.2 slot ?

After hours of videos, guides, and forums, I am still confused about how pcie lanes from CPU's and mobos work so I was hoping someone can shed some more light for me. I currently have an i7 4790k which claims to have a max number of 16 lanes via up to 1x16, 2x8, 1x8+2x4. I am planning on getting ASRock z97 Extreme9 which has 4 PCIe 3.0 x16, 1 PCIe 2.0 x16, 1 mini-PCIe. So if I understood everything correctly, which I honestly don't think I did, my 1080 ti will use 1 PCIe 3.0 x16, leaving either 1 more PCIe 3.0 x16 or 2 PCIe 3.0 x8. The ti will also use up the x16 lanes from my cpu. I plan on using two NVMe m.2, the extreme9 only allows one nvme in pcie 3.0 x4 (also referred to as ultra m.2) and the other in pcie 2.0. To get around the 2.0 bottleneck I plan on using a PCIe 3.0 x4 Nvme - m.2 adapter instead, which uses up my last pcie 3.0 x4. (well technically they are both x8 but I don't think that is relevant). I also read somewhere that cpu lanes don't matter when it comes to storage. And then I plan on using some of the sata3 connections for more storage which should be fine since ssd's and hard drives don't require pcie lanes. Am I on the right track in understanding pcie lanes, and if not can someone help explain where I went wrong?
