    0:30*...but no TV-card

  • Samsad Parbeen

    But tell me if I will be able to run nvidia gt1030 2 GB or gt730 in 'PCI-E Gen-2' as it was stated in my mother board

  • ObsoletePowerCorrupts

    1:14 I wouldn't be so hasty to assume that will work fine. Irrespective of hte 8x vs 4x bandwidth, the card might do with that particular RAID card and motherboard but the DMA can have problems when plugging a business class HBA into a domestic motherboard. So for example, it can impact on how much RAM is recognised. The video also hasn't pointed out how performance is affected (in fact sometimes dictated) by shared bandwith with storage controllers. It is a pity because in the final point he touched on that the other way around.

  • Ali Abbas

    how to know which is my pci express is 2.0 or 3.0 how can i know please help

  • Arianna Racine

    Linus, PCI-E 6 pin and 8 pin power delivery as fast as possible. Understood its for providing extra power but what does it deliver parts to and is it only nessicary for graphics processing? In other words is it nessicary to deliver power to the card if its being used for crypto mining?

  • Ben Sama

    This is very clean for being so old

  • ItsDanzGravity

    I have PCI 2.0 x16 will it run MSI GTX 1050 areo itx 4gb?

  • David L

    So, my PC's MB is old; it is PCIE X1 .

  • Martynas Globys

    I have a main board called ASRock h110m-dvs. The main board has this text writen on it: PCI Express 3.0, but i only see pcie2 and pcie1 connections on my main board. So how do i use PCI Express 3.0.

  • Trolling Gaming

    so, i can put PCIe 3 graphics card in my PICe 2 slot? thats good to know.

  • Logan Pennington

    Thank you... I was like “HOW DO I KNOW IF THIS IS COMPATIBLE!?!!?!?” Practically dying of stress. And that’s why i subscribed.

  • Robby Almendrez

    Have a question, sad to say my board Asus P5G41T-M LX3 has a pci 2.0 slot and I'm planning to buy a pci 3.0 video card, will that work? Should my system still be stable?

  • ROYAL GAMER

    can i put 2.0 pcie express graphic in pcie 1.1 x4

  • thaik56

    So basically what I have to remember is:1X time 1.0 = 250MB per secondThe rest is just a matter of multiplying.Thanks for clearing that up!

  • colo capacco

    thanks, very clear as always! AS FAST AS POSSIBLE: AFAP

  • Chris James

    okie so i loked up my damn serial number of the motherboard i still cant find out if its a x2x4 or x16 gen 3 card i know its gen 3 but i dont know what x it is ughhhhh i got a x4 card in it now 1gb i want to get atleast a 3gb gpu or get a new pc period

    Does 2.0×16 PCIe GPU Compatible On 3.0×16 Port On GA H110M-S2 ? What Are The Disadvantages. ?

  • Derek Miao

    Well done; very clear.

  • Rafael Freitas

    Awesome! Quick, clear & well-spoken ! Maybe some visual resource when u talk about generations, x16 4.0 x4 and all of those terms would help you to gather even more people aroud your channel.

  • selva .s

    Can we install PCI express X16 3.0 card in PCI express X16 1???

  • Rio Sanchez

    Can you put a pcie 2.0 video card on a pcie 3.0?

    will a GTX970 work on my bunk Biostar A960G+ mobo Kappa

  • Feynstein 100

    While it was a good explanation, many many things were left out. I had to watch like, 10 other videos to understand the terms. I'm leaving this explanation for other people like me:Firstly, PCI stands for Peripheral Component Interconnect A peripheral is anything that isn't part of the core computing process i.e. secondary (eg keyboard, mouse, GPU, LAN). PCI is thus an interface for these accessories to connect to the motherboard. While PCI was first introduced in 1992, because its speed is inherently limited (because of how the technology works), it was replaced by the PCI express (abbr PCIe) in 2004. Basically, PCIe >>>>> PCI.Now for the numbers. There are 5 types of PCIe slots/cards. They are: 1x, 2x, 4x, 8x and 16x. The numbers on these correspond to the number of lanes on the slot/card. What's a lane? A lane, like that for vehicles, is a path for data to travel. So a 1x card/slot has just one lane while a 2x has 2, a 4x has 4 and so on. And as you can imagine, doubling the number of lanes doubles the data transfer speed. Which brings us to generations As of writing this comment, there are 4 generations of PCIe: 1.0, 2.0, 3.0 and 4.0. For our purposes, the only difference between the generations is that the data transfer rate in each lane doubles with each successive generation. In PCIe 1.0, each lane supports upto 250 MB/s-> So if you had a PCIe 1.0 4x card/slot, the data transfer rate would be 4*250 MB/s = 1 GB/s In PCIe 2.0, each lane supports upto 500 MB/s-> So if you had a PCIe 2.0 4x card/slot, the data transfer rate would be 4*500 MB/s = 2 GB/sIn PCIe 3.0, each lane supports upto 1 GB/sIn PCIe 4.0, each lane supports upto 2 GB/sHope this helps :)

  • Joseph Vida

    Thanks for explaining the different generations.I bought this adapter to put a pcie x16 graphics card in my HP A518X desktop.He doesn't state if it supports generation 1 x16 graphics cards or other type generation graphics cards.I didn't realize you have to worry about generations as well as pcie 1 or 2 3 slots. https://www.ebay.com/itm/32-Bit-PCI-To-PCI-e-Express-16x-Riser-Extender-Convert-PCI-E-cards-into-PCI-slot/180735257737?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2057872.m2749.l2649

  • Time Trend

    can pci express the 3.0 hold ddr6 gpu?

  • Sameplayer

    So if I put a PCI 3 GPU in a PCI2 slot I will run but not as good as it would in a pci3 slot
