I rubbed the contacts of the video card with an eraser, took out the CPU and moved the brush over the socket. returned - it became x16 instead of x2
3 month agoIt happened on my 8700k, it turned out that when I pulled the processor out of the socket and pryed the PCB of the processor with a screwdriver, I accidentally bent it down slightly, but this apparently turned out to be enough, one of the TX legs of the PCI Express lines (PEG_TX P to be more precise), which run just below, judging by pinout 1151v2. I found this out only after a thorough inspection of the socket legs and after polishing the processor and PCI Express contacts on the video card, which did not help. Now I have fixed it, the LED near the top PCI-Express slot is now red as before (x16 mode), and not white (x8 and below), which is good)
6 months agoThank you! the legs were not bent, I scrubbed the socket with a dry toothbrush, it became X16, and before that it was X8. I have an AM4 socket.
6 months agoChel, thank you. The socket leg was indeed bent. VK worked in X2 mode... Now x16! VK has become much more stable.
6 months agoOn my GTX 690 PCIe x16 3.0 everything is ok, today I installed the GTX 1080 Ti, it is defined in GPU-Z as PCIe x16 2.0, and it says right there that the video adapter supports 2.0 and is currently using 2.0, a video card that is several generations newer and in 2.0? What is this lol? can anyone tell me?....
7 months agodude, you're a god. I have the same problem - the video card began to noticeably slow down and freeze, I looked for the reason for a long time, but I couldn’t find it, I was just about to change the card and then I accidentally noticed in the gpu-z that the pisiai costs x1. but this turned out to be not enough, because in endless topics on the forums I advise any simple trick, such as switching the card, cleaning the contacts, resetting the computer, reinstalling the driver, etc. and of course this doesn’t help at all. I will check my percentage, I hope I will find a solution.
ps: by the way, on one of the forums someone casually mentioned that the pee lines go directly to the percent and there a part may be “pinched” or something like that. those. indirectly indicates exactly the problem with the processor.
helped!!! one foot is in trouble (how come I don’t know... at first everything seemed to be intact, but when I turned on the flashlight I saw that one was shiny, when I touched it with a toothpick it turned out to have fallen off (
7 months agoIt was the same bullshit. mother (MSI Z170 PC Mate). Already in the BIOS it showed that the video card works on x8, I tried it on different cards. I took it off and sure enough, one leg was jammed. Then I remembered that when I was assembling the computer, even after the purchase I noticed that there was a problem with the legs. I bought everything new from an online store, I didn’t send it back under warranty, I just trimmed it with a needle as best I could. I assembled it, everything started up and worked. At this point I happily forgot about the dented legs. And only three years later, when I bought a used video card and tested it, I noticed that it works on x8. I scoured the Internet about this topic. In short, after re-aligning the legs under a magnifying glass, and making sure that everything sticks out as it should), I assembled the computer and everything worked as expected on x16. Well, that’s how it is, a new mother with bruised legs...
9 months agoThere was also a similar problem, VK showed either x4 or x8 but not x16, in the end it turned out that the cooler was too tight, the cooler is a noctua-14s tower, I loosened 2 fastening screws a couple of turns and voila everything worked as it should. So if none of the advice helps you, try relaxing the cooler, especially if it’s a tower cooler.
10 months agoDisclaimer for the screensaver - degenerate!
11 months agoI generally write x1. At first everything was as it should be, it wrote x16, then there was some kind of glitch with the firewood, they started crashing and a message popped up: supposedly the driver was not found and was installed again (something like that), and immediately switched to x8 mode. Then I couldn’t boot for a long time; before loading the desktop, the monitor turned off and it said cable not found. Now it starts up, but works in x1 mode. Card gtx 650. Mother on 775 socket, but from the top line.
Moreover, this card works great on another computer. Tell me, what could be the reason?
Perc: xeon 5450, bios flashed
It shows me in the window 8-3.0 / 8-1.1 when I load 8-3.0 it turns out that the card works in this mode? I don't fuck around. The processor costs Pentium G4600 lga 1151 socket and video card RX 460 sapfire 4 Gb. On the mainland there is an x16 slot, maybe I don’t understand.
1 year agoThank you, it helped, there was no bent leg, I just cleaned the contacts on the processor and PCIe from x1 became x16 as it should be.
1 year agoImbalance911 THANK YOU SO MUCH!!! The video card worked in x1 mode instead of x16, I shoot the percentage and there is actually one leg bent, and not like yours, but generally 180 degrees. I would give 500 likes, but........
1 year agoThank you!!! I have amd. In my case, the legs on the processor were not bent. I removed the processor and installed it, everything worked as it should... Guys, when you install the motherboard, do not hold it by the cooler. And if you have a heavy tower cooler, and the fan is already old and vibrates, then it might not have squeezed out many percent from the socket. Thanks to the author, I didn’t know where to look, I checked everything....
Defining one of the main interfacesPCI Express, whose full technical name is "Peripheral Component Interconnect Express" but often abbreviated as PCIe or PCI-E, is a standard connection type for internal devices such as video cards, sound cards, wifi adapters and other peripheral devices on a personal computer.
Typically, this high-speed port refers to the actual one on the motherboard that accepts traditional PCIe-based expansion cards and expansion card types.
Old video card with AGP interface PCI Express has virtually replaced PCI, both of which have replaced the oldest widely used connection type, called ISA. Although PCs can contain a variety of expansion slots, PCI Express is considered the standard internal interface for the fastest slot. Today, many personal computer motherboards are manufactured only with PCI Express connectors.
Like older standards like PCI and AGP, the Express-based device physically goes into a high-speed connector on the motherboard.
The interface of this connector provides high-speed communication between the device and, as well as other equipment.
Although not very common, there is also an external version of the high-speed port, unsurprisingly called External PCI Express, but often shortened to PCIe. ePCIe devices that are external require a special cable to connect any external PCIe device to the PC through a PCIe port, usually located on the back of the PC, supplied either by the motherboard or a dedicated internal PCIe card.
With the demand for faster, more realistic video games and video editing tools, graphics cards were the first types of computer peripherals to take advantage of the benefits offered directly by PCIe.
While graphics cards are still the most common type of PCIe card, you'll find other devices that connect to the motherboard, processor, and RAM much faster. It is also increasingly common to make PCIe connections instead of conventional PCI. For example, many high-end sound cards now use a high-speed port, as well as an increasing number of wired and wireless network interface cards.
Hard drive controller cards may be the most useful for PCI-E after the video card. Connecting a high-speed to this high-speed interface allows you to read and then write the disc much faster. Some PCIe hard drive controllers even include an integrated SSD, greatly changing how storage devices are traditionally connected inside a PC.Of course, with PCIe being replaced by PCI and AGP entirely on newer motherboards, almost every type of internal expansion card based on older interfaces is being rebuilt to be able to use the PCI Express bus. This includes things like expansion cards, Bluetooth cards, etc.
Showing the various controllers on the motherboard Express x1 ... Express 3.0 ... Express x16. What does "x" mean? How do you know if your PC supports it? If there is a PCI Express x1 card, and there is only an Express x16 slot, does it work compatible? If not, what are your options?
It's often not entirely clear when you buy an expansion card for your computer, such as a new graphics card, which of the various PCIe technologies works better with your PC than the other. However, as complex as it is, it looks quite simple once you understand two important pieces of information about a high-speed port: the part describing the physical size and the part describing the technology version, as described below.
As the title suggests, the number after the x indicates the physical size of the PCI-E card or slot, with x16 being the largest and x1 the smallest.
Here's how the different sizes are formed:
Regardless of the size of the high-speed port or card, the key notch, that small space in the card or slot, is always located at pin 11. That is, the length of pin 11 continues to increase as we move from PCIe x1 to PCIe x16. This allows you to flexibly use cards of one size with slots of another.
PCIe cards fit in any high-performance port slot on the motherboard that is at least as large. For example, a PCIe x1 card will fit into any PCIe x4, PCIe x8, or PCIe x16 slot. The PCIe x8 card will fit into any PCIe x8 or PCIe x16 slot. PCIe cards that are larger than a PCIe slot can fit into the smaller slot, but only if that PCI-E slot is open (i.e. does not have a plug at the end of the slot).
Radeon PCI-Express x16 graphics card In general, a larger Express card or slot will support more performance, assuming the two cards or slots you're comparing support the same version of PCIe.
Any number after PCIe that you find on a device or motherboard indicates the latest version number of the PCI Express specification being used.
Here's how the different versions of the PCI Express controller compare:
All versions of the high-speed port are backwards and forwards compatible, meaning no matter what version your PCIe card or motherboard supports, they should work together at least at a minimum level. As you can see, major updates to the port standard dramatically increase throughput each time, greatly increasing the potential of what the associated hardware can do.
The version's improvements also include bug fixes, added features, and improved power management, but the increase in bandwidth is the most important change to note from version to version.
As you read in the sizes and versions sections above, uses almost any configuration you can imagine. If it's physically fit, it probably works...that's great. However, it's important to know that to increase bandwidth (which usually equates to maximum performance), you need to select the highest PCIe version supported by your motherboard and select the largest size of a given port that will fit.
For example, a graphics card with a 3.0 x16 high-speed port will give you maximum performance, but only if the motherboard supports the 3.0 high-speed port and has a free x16 high-speed port. If the motherboard model uses PCIe 2.0 exclusively, the card will only run at the supported speed (for example, 64 Gbps in an x16 slot).
Most motherboards and personal computers released in 2013 or later likely support Express v3.0. If you are unsure, check your motherboard or PC manual. If you can't find any definitive information about the PCI version your motherboard can use, I recommend buying the largest and latest version of PCIe card, if it fits, of course.
VR virtual reality glasses Video game developers are always looking for games that become increasingly more realistic, but can only do this if they can transfer more data from their game programs to a VR headset or PC screen, and this requires faster interfaces. Because of this, PCI Express will not continue to dominate its laurels. PCI Express 3.0 is amazingly fast, but the world is striving for incredibly fast transfers.
PCI Express 5.0, due to be completed by 2019, will use 31,504 gigabits per second of bandwidth per lane (3,938 megabytes per second), twice as much as the high-speed slot version 4.0 offers. There are a number of other interface standards other than PCIe that the tech industry is looking at, but since they will require major hardware changes, PCIe looks set to remain the leader for some, a long time as the fastest ever.
The PCI Express standard is one of the foundations of modern computers. PCI Express slots have long occupied a strong place on any desktop computer motherboard, displacing other standards, such as PCI. But even the PCI Express standard has its own variations and connection patterns that differ from each other. On new motherboards, starting around 2010, you can see a whole scattering of ports on one motherboard, designated as PCIE or PCI-E, which may differ in the number of lines: one x1 or several x2, x4, x8, x12, x16 and x32.
So, let's find out why there is such confusion among the seemingly simple PCI Express peripheral port. And what is the purpose of each PCI Express x2, x4, x8, x12, x16 and x32 standard?
Back in the 2000s, when the transition took place from the aging PCI standard (extension - interconnection of peripheral components) to PCI Express, the latter had one huge advantage: instead of a serial bus, which was PCI, a point-to-point access bus was used. This meant that each individual PCI port and the cards installed in it could take full advantage of the maximum bandwidth without interfering with each other, as happened with a PCI connection. In those days, the number of peripheral devices inserted into expansion cards was abundant. Network cards, audio cards, TV tuners, and so on - all required a sufficient amount of PC resources. But unlike the PCI standard, which used a common bus for data transfer with multiple devices connected in parallel, PCI Express, when considered in general, is a packet network with a star topology.
PCI Express x16, PCI Express x1 and PCI on one board
In layman's terms, imagine your desktop PC as a small store with one or two salespeople. The old PCI standard was like a grocery store: everyone waited in the same line to be served, experiencing speed issues with the limitation of one salesperson behind the counter. PCI-E is more like a hypermarket: each customer follows his own individual route for groceries, and at the checkout, several cashiers take the order at once.
Obviously, a hypermarket is several times faster than a regular store in terms of speed of service, due to the fact that the store cannot afford the capacity of more than one salesperson with one cash register.
Also with dedicated data lanes for each expansion card or built-in motherboard components.
Now, to extend our store and hypermarket metaphor, imagine that each department of the hypermarket has its own cashiers reserved just for them. This is where the idea of multiple data lanes comes into play.
PCI-E has gone through many changes since its inception. These days, new motherboards typically use version 3 of the standard, with the faster version 4 becoming more common, with version 5 expected in 2019. But different versions use the same physical connections, and these connections can be made in four main sizes: x1, x4, x8 and x16. (x32 ports exist, but are extremely rare on regular computer motherboards).
The different physical sizes of PCI-Express ports make it possible to clearly divide them by the number of simultaneous connections to the motherboard: the larger the port is physically, the more maximum connections it can transmit to the card or vice versa. These connections are also called lines. One line can be thought of as a track consisting of two signal pairs: one for sending data and the other for receiving.
Different versions of the PCI-E standard allow different speeds on each lane. But generally speaking, the more lanes there are on a single PCI-E port, the faster data can flow between the peripheral and the rest of the computer.
Returning to our metaphor: if we are talking about one seller in a store, then the x1 strip will be this only seller serving one client. A store with 4 cashiers already has 4 lines x4. And so on, you can assign cashiers by the number of lines, multiplying by 2.
Various PCI Express cards
For the PCI Express 3.0 version, the overall maximum data transfer speed is 8 GT/s. In reality, the speed for the PCI-E 3 version is slightly less than one gigabyte per second per lane.
Thus, a device using the PCI-E x1 port, for example, a low-power sound card or Wi-Fi antenna, will be able to transfer data at a maximum speed of 1 Gbps.
A card that physically fits into a larger slot - x4 or x8, for example, a USB 3.0 expansion card will be able to transfer data four or eight times faster, respectively.
The transfer speed of PCI-E x16 ports is theoretically limited to a maximum bandwidth of about 15 Gbps. This is more than enough in 2017 for all modern graphics cards developed by NVIDIA and AMD.
Most discrete graphics cards use a PCI-E x16 slot
The PCI Express 4.0 protocol allows the use of 16 GT/s, and PCI Express 5.0 will use 32 GT/s.
But currently there are no components that could use this number of lanes with maximum throughput. Modern high-end graphics cards usually use x16 PCI Express 3.0. It makes no sense to use the same lanes for a network card that will only use one lane on the x16 port, since the Ethernet port is only capable of transferring data up to one gigabit per second (which is about one-eighth the throughput of one PCI-E lane - remember: eight bits in one byte).
There are PCI-E SSDs on the market that support the x4 port, but they look set to be replaced by the rapidly evolving new M.2 standard. for SSDs that can also use the PCI-E bus. High-end network cards and enthusiast hardware such as RAID controllers use a combination of x4 and x8 formats.
This is one of the most confusing problems with PCI-E: a port can be made in the x16 form factor, but not have enough lanes to carry data through, for example, just x4. This is because even though PCI-E can carry an unlimited number of individual connections, there is still a practical limit to the chipset's bandwidth capacity. Cheaper motherboards with lower-end chipsets may only have one x8 slot, even if that slot can physically accommodate an x16 form factor card.
Additionally, motherboards aimed at gamers include up to four full PCI-E slots with x16 and the same number of lanes for maximum bandwidth.
Obviously this can cause problems. If the motherboard has two x16 slots, but one of them only has x4 lanes, then adding a new graphics card will reduce the performance of the first by as much as 75%. This is, of course, only a theoretical result. The architecture of motherboards is such that you will not see a sharp drop in performance.
The correct configuration of two graphics video cards should use exactly two x16 slots if you want maximum comfort from a tandem of two video cards. The manual at the office will help you find out how many lines a particular slot has on your motherboard. manufacturer's website.
Sometimes manufacturers even mark the number of lines on the motherboard PCB next to the slot
You need to know that a shorter x1 or x4 card can physically fit into a longer x8 or x16 slot. The pin configuration of the electrical contacts makes this possible. Naturally, if the card is physically larger than the slot, then you won’t be able to insert it.
Therefore, remember, when purchasing expansion cards or upgrading current ones, you must always remember both the size of the PCI Express slot and the number of lanes required.
