why does it require 4 lanes on PCI gen 3? according to PCI gen 3 specs, 1 lane gives 1Gigabyte (so that's 5Gbits up / 5Gbits down) and 2 lanes should be enough to give the full 10Gbits
Chat GPT answer : The number of lanes in a PCI Express (PCIe) connection is determined by the bandwidth requirements of the devices connected to it. While it's true that, according to the PCI Express 3.0 specifications, one lane can theoretically support a data rate of 1 GT/s (gigatransfer per second) in each direction, providing a total of 8 Gb/s (gigabits per second) in full-duplex mode, there are several factors to consider. Firstly, the specified data rates are theoretical maximums, and real-world performance may be lower due to factors such as protocol overhead, encoding, and other signaling considerations. Secondly, devices that use PCIe lanes often require a certain level of bandwidth to operate optimally. For example, a device that requires 10 Gb/s of effective bandwidth might use a x4 connection to ensure it has sufficient throughput. This accounts for protocol overhead and variations in real-world performance. Additionally, some devices or applications may benefit from the additional bandwidth provided by more lanes. For example, high-performance graphics cards, storage devices, or network adapters may require more than x1 or x2 lanes to achieve their maximum performance. While it's technically possible to use fewer lanes for certain applications, designers often opt for a higher number of lanes to ensure compatibility with a broader range of devices and to future-proof their systems against increasing bandwidth requirements. In summary, the choice of the number of lanes in a PCIe connection is influenced by the specific requirements of the connected devices and the desire to provide sufficient bandwidth for optimal performance.
So what is the transfert rate for upload. On the 25.g bcus of realtex chip is limited to 1 gyg on upload but 2.5 ob download. Is this better or the same? Thanks
@@GadgetsOfTM Thanks for the reply. I had a x520 with dac sfp+ adapters through a 2.5g switch with 2 sfp+ port with a 10gb rj45 connection coming from the router and transfer was max speed of connection 1600kps upload and download. put a tplink 2.5 gyg card max upload 1 gyg but download at 1.6. Saw other comments with same results elsewhere.
Twiejk? Great info buddy!
Tanks for this good video .. this will work Dell Power Edge T350 Server ?
As lolng as it features PCIe in x4 format, yes it will as drivers will work in Server versions.
mine keeps disconnecting at night? I did the update online with no CD is that why?
Prevent the adapter from entering power saving mode. That is most likely the problem.
@@GadgetsOfTM done thanks

That would be a great question for the developer. What we can tell you is that our experience with this NIC has been great.

No bottlenecks there.

Are network card good for multiplayer game like reducing its ping latency?
Latency will most likely not be affected by using higher data rate cards. Unless of course bandwidth is saturated at 1 Gbps
Is it compatible in the qnap TS853A?
We have not been able to test it in NAS, but having support for linux drivers is a matter of installing those drivers.
