Hi, is there any way to know the distance between pcie slots before buying the mobo? cant find such info on both msi and gigabyte official sites. Trying to figure out if i install my Asrock AMD rx 7800xt challenger oc on new mobo (trying to choice one) how many pcie slots gets wasted.

Hey guys, I've just upgraded my GTX1080 to a new AMD 7900XT GPU. The new GPU blocks access to the bottom most PCIex16 slot, which previously housed my capture card. (I'm trying to avoid doing the obvious things like getting an ATX size board, or selling the capture card and going for an external one.) Here are the relevant details about my system. Motherboard: Asus TUF B550m plus (this is an mATX size board) GPU: 7900XT GPU Capture card: Elgato 4k60 Pro Case: Corsair 220T Anyways, I managed to get the 7900XT installed in the top PCIex16 slot on my board (lets call it PCIex16_1). However, my problem is that this new GPU is so thick that it blocks my secondary PCIEx16 slot (PCIex16_2). I was using PCIex16_2 with my Elgato 4k60 Pro capture card before, and now no longer can fit both simultaneously. SO I had the bright idea to just move the GPU down to PCIEx16_2. And move the capture card up to PCIEx16_1; everything seems to be running fine so far. Can someone help me understand what kind of performance hit I may take with the GPU in PCIex16_2? I know PCIex16_1 is 4.0 while PCIex16_2 is 3.0, but isn't 3.0 already enough bandwidth if I have enough lanes? Thanks!

Afternoon folks, I’m having some issues with my ~6 year old pc. I was performing a fresh install of Ubuntu, which this pc has handled before fine with all the same hardware as what’s in it now, but this time I was having trouble installing, with errors making reference to PCIe. Initially I tried removing all the ram, as I’ve had problems with faulty sticks before with this pc, but after testing different combinations, no progress was made. Then I took out my wifi card, and then the install went fine. Went to reinstall it after the os was installed, but the status led never lit up. Tried in different PCIe slots, no change. Went to local hardware shop and bought another cheap wifi card, assuming that my old one had just failed on me, but after installing that, no status light on that either, and not showing up on the os. Reset the CMOS, no change either. Also have unplugged and replugged all motherboard power connectors to the psu. Any other troubleshooting steps I could take? note: one thing I tried was changing the hdmi cable from my gpu to the motherboard to use the integrated graphics on my cpu. System wouldn’t post after this, gave 5 beeps from the pc speaker… this has worked before. Moved back to the gpu and it posts fine. mobo is Gigabyte Z370P-D3, if that helps

Hey guys a short story of what is going on, I am a small time youtuber very small time and I built my first PC back in may of 2023. while checking the pc I used my capture card in all 3 ports to make sure they worked since I didn't have a graphics card yet and I noticed that the third slot controlled by the chipset wasn't working there is power to the capture card as I can see my Xbox on the tv but the pc cannot see the device in device manager or any software. Fast forward to November and I finally have a 6700 xt graphics card. I start to use it in the primary slot but the third slot where I need to use the capture card since it requires a x4 slot is showing the same issue. ASRock tech support recommended updating the Bios which I was unable to do so they replaced the entire motherboard. Now: I have the new motherboard but I am seeing all the exact same issues. Third PCIE slot doesn't work. Cant update board bios, cant run updates for my Chipset or my graphics card either. Any time I try to run an update it gets stuck in a load screen. Any help would be much appreciated, first new PC and first PC Build. CPU: Ryzen 9 7900X OS: Windows 11 Motherboard: ASRock B650E PG RIPTIDE WIFI Ram: G.Skill Trident Z5 Neo RGB 32 GB (2 x 16 GB) DDR5-6000 CL30 Memory C Drive: Samsung 970 Evo Plus 500 GB M.2-2280 D Drive: Samsung 970 Evo Plus 500 GB M.2-2280 E Drive: Western Digital Blue 6 TB 3.5" 5400 RPM

A few months ago I bought a Supermicro tower server. I have been using 4 (+1 boot) SATA SSD drives and running TrueNAS Scale on it. Just now I switched out the SATA cabels that were connected directly to the motherboard to an HBA. And now the server won't turn on. And I don't mean it wont POST or BOOT. It won't even power on. When I disconnect the HBA and the PCIE riser, it POSTS fine. Even if I only connect the riser by itself with nothing at the other end of it, same issue. I tried two different risers and same thing happens. The HBA is a Broadcom 9300-16i, but since the problem happens even without it connected I don't think it's an issue. Is it just some BIOS setting I am missing? Is my motherboard faulty? Here are the specs: Mainboard: Supermicro X9DRW-IF CPU: 2 x Intel Xeon 2680 V2 RAM: 16 x 16 GB DDR3 1333 MHz ECC PSU: 500 W (Bronze)

Budget (including currency): $1,000 Country: USA Games, programs or workloads that it will be used for: ? Probably F1 2023 Other details (existing parts lists, whether any peripherals are needed, what you're upgrading from, when you're going to buy, what resolution and refresh rate you want to play at, etc): https://pcpartpicker.com/list/sdTTDZ My question is about the "14 total / 10 usable" Native PCIe lanes here: https://www.amd.com/en/product/14086 I am ready to spring for an 8500G. Assume my 8500G choice is locked. What is a good motherboard that has 2 x USB4 to take advantage of those pins coming from the CPU, and as much PCIe expansion as possible? Assume I'll keep the motherboard for 15+ years. Eventually I'll get some faster AM5 CPU to put in it. The ASUS ROG X670E crosshair hero almost seems like a good choice. (The manual is here) Explanation: The ROG X670E strix has 1 DisplayPort 1.4 output on the rear I/O but no USB4. The ROG crosshair has 2 x USB4 display outputs from the CPU. And the 8500G has 2 x USB4 ports. But I'm still nervous I missed something that's going to bite me later. What will be the limitations on PCIe slots? If the CPU had a full 16 lanes for the x16 the manual then talks about bifurcation on p. vii "specifications summary" -- The second PCIe 5.0 x16 slot works only in x8 mode: "(support x16 or x8/x8 mode)" And "When PCIE 5.0 M.2 card is installed on PCIEX16_2, PCIEX16_1 will run x8 only." Some of that is pretty normal for X670E motherboards based on [1]. What I'm wondering is what happens when the APU only has 10 usable PCIe lanes? Will the second x16 stop working at all - same for the slots M.2_1 and M.2_2 which each use x4 of PCIe 5.0, they prob will just not work at all. So I have to use M.2_3 and M.2_4 which are PCIe 4.0 x4 - that doesn't seem so bad. I do see that pcpartpicker flags the 5800G CPU as being so new I'll need to flash the motherboard BIOS before I can install it. That's the $650 ASUS board that I'm looking at. Now, I hear you, you'll cringe at spending that much on the motherboard. Motherboards have gotten pricey lately, so I'm looking to buy an excellent one and to really peer into its guts. I mean, I looked at the ASRock X670E Taichi Carrara for $623 and it has the same warning, "support x16 or x8/x8 modes*" and probably has the same gotcha if M2_1 is used. Gigabyte seems to have discontinued the X670E Aero D, and the AORUS Master limits its USB-C to DisplayPort 1.4. MSI has the same DisplayPort 1.4 limitation. Anyone already have the ROG crosshair or ASRock Taichi Carrara? [1] https://www.techpowerup.com/review/asus-rog-crosshair-x670e-hero/

Thanks to a friend that gifted me this piece of add-in card during the Festive season, I now find myself wondering which 4TB PCIE SSD I should go for in order to replace my 2x3TB Toshiba P300. I'm looking at the Samsung 990 Pro since: I already have a 980 (yes, it's the non-Pro, I didn't omit the Pro), and knows it's performance characteristics. I also have 2 more 870 EVO 4TB, so pretty much Samsung ecosystem. I can walk to multiple local shops and purchase one. TLC-based and has DRAM cache Except ONE issue, it cost $500-$550, after currency conversion and tax from US$. The two 3TB drives I'll be replacing are my Workspace/Documents/Downloads and Game Records, and yes, I know the add-in card splits PCIE 3.0 x4 into PCIE 3.0 x1, but in the future (5-7 years--already 3 years, based on my upgrade cycle), I can get the 'full' potential of the 4TB PCIE SSDs. Plus, it's still PCIE 3.0 x1, still faster than SATA. Here are the 4TB I can: Go down and purchase Doesn't have heatsink Below $420 They are: Adata XPG S70 Blade Adata Legend 960 Lexar NM790 (Not looking at this, since it's HBM/DRAM-) Crucial P3/+ (Not looking at this, QLC and HBM/DRAM-) Are those two comparable to 990 Pro? I'm discourage of looking at NewEgg or A to Z (Amazon), because the waiting time is two weeks---big OOF.

Booting the pc with the adapter plugged in just gives me a near blank frozen screen and the cpu heara up, booting without the adapter is fine tho. I updated the bios to the latest version. Anyone have any suggestions? 20240126_201658.jpg

Morning all, there's a used Samsung PM1725B locally, trouble is the card is designed for PCIE x8 and my motherboard (gigabyte b550 ud ac) has open slots that are physically x16 but wired for x4 or x1, what issues will occur running this card in those slots? Also ive heard tell that any cards will run in a slot with fewer lanes than what a card is wired for as long as there is not a physical limit but i couldnt find a solid source on this.

Hey Guys, I've never been more at a loss for a PC issue than I am now. For context I run a side Hussle building PC's and fixing them. I'm not at the level of some of out forum members but to date never had a PC build come back or an Issue I've not been able to fix Eventually. My PC Specs are - Ryzen 7 3700X - RTX 3070TI - 32Gb DDR4 RAM - B450 Tomahawk MAX- C: M.2 on Mobo........ 1 M.2 on PCI Adapter and 1 HDD. For many months I've been having Blue Screen Crashes with various error code but most pointing to a Windows Install Issue. Occasional one being GPU issue. I decided to reinstall Windows 10. The installer failed to install 2 times. So I decided to try Windows 11 (I had "upgraded" to windows 11 when it came out and hated it so went back. I hoped the things I hated had been ironed out). The Windows 11 Install failed also. I eventually got Windows 11 Installed but my issues just shifted towards GPU Problems. Crashes but not blue screen most alluding to GPU Memory issues. I've googled fixes and reinstalled drivers all to no avail. Just before I wrote this was the strangest example I've seen. All 3 of my monitors got no signal, all my lights on the Mobo went off (Ram Mobo GPU lights) I thought it'd just crashed but I could still talk to my mates on Discord. It did it twice in the space of 2 Mins. Both times just coming back on like nothing happened. I don't expect with this limited information to get a instant fix but is there any troubleshooting steps you guys can think of to help me narrow this down as the "5 ways to fix gpu error" articles and my own experience has proven useless. Thank you in Advance

I'm planning out a pretty alright gaming, productivity, and DIY Machine Learning machine to use for the next 5-10 years. To this end I'm planning to run a 7950x with dual 3080TIs I purchase second hand (very affordable around me!), but to leverage them fully for my ML purposes I think I need two PCIe3 x16 slots. The motherboard I was considering is the AsRock x670E Steel Legend. Going off the manual [link] though, this motherboard has one PCIe5 x16 slot, and then another PCIe3 x4 slot lower down the board. Is this correct? Would the CPU direct more lanes to the second GPU, or limit it's bandwidth? I don't really understand how PCIe works to be honest. If this motherboard isn't feasible for what I want to do, are there any other relatively affordable (300-500 CAD) x670 or B650 motherboards that would work for what I'm describing? The market is so overwhelming right now and I have such a particular feature set in mind that I'm a little swamped and any help is appreciated. EDIT 1: I just found the MSI MAG x670E Tomahawk Wifi, which falls right in the middle of my budget range at $420 CAD, and also seems to support dual PCIe4 x16, which would be perfect. Is this board actually as good looking as it seems? Does anyone have experience with it?

Hi. Has anyone else tried non graphics PCIe cards in an eGPU enclosure? I did see in one of the LTT M1 Mac reviews that showed a 10G ethernet card working within a Razer Core X on a new M1 chip. Perhaps this is something that could be explored in an LTT to show other ways of gaining connectivity (obviously with some performance penalty due to running Thunderbolt and not having it directly in a PCIe slot). Even with a supposed performance penalty I was able to run 4 seperate 4K at 60Hz display outputs with hardware playback from a video projection program called Madmapper from an MSI RX580 in the Razer Core X connected to a 2018 Macbook Pro running an i5 with no stuttering or crashes for over 4 hours in a sub optimal test conditions. Cards that would be of interest that could be used in the Razer Core X would be the Avid HDX DSP card, Blackmagic Design DeckLink 4K60 Quad HDMI Recorder Capture Card, Dante PCIe-R Soundcard and Universal Audio Octo "Core" UAD-2 PCIe DSP Accelerator. These can only currently be used with a Mac Pro due to them being PCIe which is less than ideal for quite a number of reasons least of which being price and the form factor (portability to have a mobile streaming/audio recording setup (as in it can fit in two Pelican cases) ). Could this be a way get PCIe cards to work without having to have physical PCIe slot in a computer and could this mean that proprietary cards could still run on newer computers and provide some form of backwards compatibility? (obviously these would need drivers to work and will Apple being a**holes about what drivers can be used on MacOS (talking about AMD RX6000 series) this may be an even bigger issue. But from those cards I listed above they all have MacOS compatible drivers which currently run but with a direct PCIe connection TIA for any thoughts or info

I bought a Acer Predator gm7000 2tb but it’s read speed is normal but its write speed is very slow and it is at pcie 3.0 and pcie 4.0 is supported and I did put it in a pcie 4.0 slot on my motherboard .

Hello! I am looking to buy an AMD Ryzen 7 5800X, along with an AORUS Elite B550m Motherboard. While both of these parts support PCIe gen 4.0, my graphics card (ASUS Dual GTX 1660 Super) only supports up to PCIe gen 3.0. I need guidance on how to avoid compatibility issues or if other components would suit my current graphics card better. I imagine I can change the BIOS settings to run at PCIe gen 3.0, however I have never done that myself so I don’t feel comfortable going into it blind. I live in Hungary and my budget is around 500USD. Thank you for your replies in advance! Regards, Butterdog420

I'm looking at nvme drives for my computer but I'm confused on the pcie lane usage. My motherbord NZXT N7 b650e has 3 nvme slots they are pcie 5.0 x4 mode, pcie 4.0 x4 mode, and pcie 4.0 x2 mode. The first 2 slots are connected to the cpu and the 3rd is the chip set. I want to use the first 2 slots for speed. From my understanding there is only 20 lanes available to the cpu. My question is would I be able to use both nvme slots to the cpu without negatively affecting my gpu or stealing lanes from it. GPU navidia 3080FE CPU ryzen 9 7900x Motherboard n7 b650e Attached is my motherboard owners manual 1683790896-motherboards_n7-b650e_digital-manual_230419_v5.pdf

Hello all, I'm a bit confused regarding the Pcie-lanes my motherboard has. Specs: R5 2600x Asus prime b450 plus Rtx 3070 I just bought recently a new nvme m.2 ssd and I want to transfer some data from my old one to the new one (eventually i would use both at the same time). I would buy a pcie to m.2 adaptercard and place it in my 2nd pcie 2.0 x16 slot. My problem is I DON'T want that my pcie3.0 x16 gets downgraded to x8 and the pcie 2.0 runs in x8. (In bios I have the bifurcation option, It's on auto tho). So i looked the specs up in the manual but I'm a bit confused about it, I hope u can help my with clarification . 1. Does the 2nd pcie x16 only run @4 or it could run faster (like if I would use a x16 adapter card instead of a x4). Or is it only a x16 slot with wiring only for x4? 2. I know that the 2nd pcie get the lanes from the chipset but if it would run in x8 mode would it take it from the cpu? Thanks people! Have a nice evening/day

So recently I have been having issues with my motherboard and I unplugged my GPU and I don’t know if scratching is normal on pcie slots, please help because I’ve noticed the same thing on my ram

Hy all, I don't know if im just boosted or overlooking something. Specs.: Asus prime b450 plus R5 2600x Rtx 3070 zotac Nvme m.2 Samsung evo 970 I just discovered today that my Gpu only running with 8Gt/s max in a Pcie 3.0 x16 slot. Does anyone a idea why is that I don't get the 16Gt/s? The picture was taken under load. Thanks!

Hello guys I have probably the most dumb problem. I have c850 nzxt psu and it has modular cables and I attach my pcie cable to the psu. Now I bought gpu rgb extension cable and for some dumb reason female connector is not pcie it is eps(cpu), but end of it have male pcie connector. So I don't know what to do. Should i buy adapter to pcie to eps so i can connect this two, which means I would have Psu->pcie->pcie to eps adapter->eps to pcie extension cable->pcie to 12gpu.

Situation : ryzen 7 5800x3d slightly damaged on the corner , all pins fine , cpu works perfectly through benchmarks but gpu doesnt work in the first pcie slot on the mobo but does work in other slot . Could the cpu be the culprit of the non functional main pcie slot , or is the slot just busted . Im asking this cuz im looking to buy this cpu(just the cpu) from someone and he says he doesnt know if the cpu is causing the pcie slot problem or if its just the mobo . I appreciate all feedback , thanks in advance

Hello together, i just bought and installed the MSI MPG B550 GAMING PLUS Motherboard in my PC. With a Ryzen 9 3900x. (btw i use arch ) As i like to use Gpu Passthrough I put the fist GPU (rx580) in the fist slot and my second GPU(rtx2070s) in the second. Both gpu's work fine in the fist slot but in the second neither of them works. So I updated the bios in hope it will work after the update but it didn't . So here's my question. Is the second PCIE slot broken? Or is it just disablet in the bios? I would like to know because then I could still replace it with a new one. Does any one had the same issue ? Thank you very much for your replies. veerteex

Hello, I am planning to buy a Biostar B550MXC PRO motherboard and want to use it with R5 5600x processor. the motherboard has PCIE 3.0 x16 slot (running at 1x mode). If I use a GPU in that slot can get video output? I will us the pc as Truenas server . The PCIE x16 (running at 16x mode) will be used for pcie to nvme expansion card. Thanks in advance

I've got a NAS I built three years ago back when I was still young and dumb. It has a motherboard with just a single PCIEe slot. I use the NAS for media storage and run a Plex Media Server off of it. The OS is TrueNAS Core and I have been loving the experience. So much so that I also upgraded all of my networking to 10gig. I added a 10gig PCIE card to the NAS and off i was. Now that the networking has improved I tend to store higher quality media on the server. Since then, my Plex experience has been rough because my poor Intel Core i5 can't handle all the transcoding. So I want to add a GPU of some sorts. Still on the fence which GPU to get because transcoding is kind of in flux with the AV1 revolution. I'm not looking to buy a new card though, so RX7000 and RTX4000 are out of the question. Any budget suggestions are welcome My real issue is that I obviously only have one PCIe slot. I think it's PCIe gen 3 even. Does anyone know a way to convert the single slot to dual slots? I was thinking of maybe some kind of riser but I can't really find what I'm looking for. Thanks!

Hi all! Recently, I purchased two NVMe drives, but the M.2_1 slot, which is powered by the CPU, does not recognize either drive. However, the M.2_2 slot recognizes both drives without any problems. Here are my specs (Have linked the relevant Items for Ease of investigation) Motherboard: MSI B550 PRO VDH WiFi CPU: AMD Ryzen 7 5700G GPU: AMD Radeon RX 570 RAM: 16GB (2x8GB) DDR4-3200 CL16 NVMe 1: Addlink S70 Lite 512GB (Currently is being used as the boot drive in the M.2_2 slot) NVMe 2: Samsung 980 1TB What i've tried so far BIOS Reset Boot without the GPU Tried manually setting the PCIe Gen in bios Switched from UEFI to CSM and back multiple times Switched from AHCI to RAID and back multiple times I contacted the store, and they told me that the M.2_1 slot is Gen 4 only. However, after checking the motherboard and CPU specifications, I found that the M.2_1 slot should technically run as a Gen 3 slot. Any Advice/Help is Greatly appreciated Thank You!

Here is the thing...I upgraded my PC several months ago. Mainly added water-cooling kit for my Gigabyte 3090 Turbo (it's too noisy). Then I found it is (physically) not compatible with my motherboard, ROG Z690-I WIFI. So I bought a PCI-E riser for my GPU. After that, the nightmare comes, my PC will crash in heavy load such as gaming. It will directly power off sometimes (sudden black screen, all RGB lights off) and in other cases it will just freeze (screen content paused, RGB light effects paused and no response to mouce and keyboard actions). I can't guarantee it will happen everytime, but it happens frequently. When I tried to troubleshoot, I found that there were tons of WHEA code 17 Errors in my system logs as shown in the pic. The details are same: A corrected hardware error has occurred. Component: PCI Express Root Port Error Source: Advanced Error Reporting (PCI Express) Primary Bus:Device:Function: 0x0:0x6:0x0 Secondary Bus:Device:Function: 0x0:0x0:0x0 Primary Device Name:PCI\VEN_8086&DEV_464D&SUBSYS_86941043&REV_02 Secondary Device Name: Then I tried to manually set my PCI-E Speed to "Gen 3" in my BIOS, the errors were all gone. And I haven't encountered crashs anymore. I think it could be this PCI-E riser's problem, product page: https://www.amazon.com/ASUS-ROG-Flexible-Extender-Extension/dp/B082G52H1L. Note: I bought this riser on Taobao and the seller said there are two versions, one for PCI-E Gen3 and one for Gen4, I chose Gen4 version. When I search this riser for this link I didn't get any official info for Gen4 version. All of the information indicates that it's a Gen3 riser. Could this be the problem? Did ROG have this product, maybe not for retail? I found a bro who had the same issue, links: https://rog-forum.asus.com/t5/previous-forum/rog-strix-z690a-gaming-wifi-whea-17-errors/m-p/879502 If anyone need more information, please let me know.
