Purchased the x520-da2 NIC card. Works well and able to set up VLANs.

These things have been amazing in my home lab upgrade. They popped right into my VMware box and were detected without any need for manual driver updates. Each of my VM boxes are not getting 20gbs aggregated... It's been such a game changer for my lab.

Needed an Intel NIC for my TrueNAS. This has been great and will be even better once I upgrade to 10gb switches.

Installed in my PC and booted up. The light on the NIC flashed and indicated it was connected to 10G but Windows showed "no internet connection". Moved to my onboard NIC (2.5Gb) and it was fine. Went back to the 10G and it worked for a while, and well. Rebooted my PC and now it refuses to detect the NIC. Tried installing generic Intel drivers, the ioplex drivers, and letting windows detect it, nothing is working. Reseated the card, rebooted, still nothing. It just doesn't get properly detected by Windows. I knew the price felt too good to be true.

Cheaper than a network switch so decided to use this to bridge two home PCs together. Worked great after installing drivers.For installing drivers, what worked for me was downloading the X540-10G-2T-X8 (JLX540-AT2) chip package from the QR code on the back of the network card.This takes you to an intel site where you should download "Intel® Ethernet Adapter Complete Driver Pack" after clicking "Show All". Unzip the downloaded file and go to your windows Device Manager. Here you will see some unidentified devices. Right-click each of them and click on "Update Driver".Next, select the option to look for drivers locally. Then, point it to the extracted intel drivers folder. Windows will automatically look for the correct drivers recursively. I had to do this process for both network interfaces on the card.And viola, it works perfect.

I was a bit worried about operating system compatibility, because the product desription doesn't explicitly list Windows 11 as being supported. I was prepared for manual driver installation, but I was pleasantly surprised that Windows recognized the card and automatically installed/configured the software for it. The network card works and perfoms as expected.I am using this network card in a generic PC with an MSI MPG Z490 motherboard (MS-7C79), running Windows 11 Pro Ver.10.0.22631. I'm using 10Gtek 10GBase-SR LC transceivers and LC OM3 fiber cables.

My use case is a personal development network with two high end desktop workstations, one with AMD Ryzen 9 and the other with Intel i7. Both are running Ubuntu Linux 22.04.2 PRO and I am using a Mikrotik CRS306-4S-1N switch. Both Desktop systems have dual 10G NICs and cable into the switch with 6COM 6C-SFP-10G-T SFP+ 10G RJ45 Adapters and CAT8 cabling.As soon as everything was plugged in the systems came right up and everything was fast and sweet.Don't forget to plug in the backhaul cable from the switch to your in-house network feed otherwise no DHCP and the 10G connections don't com up.Highly recommended. This is plug and play and the most practical sense. Installation time was about an hour and that include putting boards in two machines, running cables, attaching adapters and installing switch. "Settings/Network/Ethernet/Wired/enp11s0f0 showed connected at 10000 Mb/s immediately.My one extra thought though is that the dual channel boards are only a little bit more, and by the time you bother to open up the box and install a board, you might as well think of the future, IMHO.

Got this for my Proxmox machine; It works fine with a Windows 2019 VM but TrueNAS Scale and Ubuntu VMs not so much – they get a valid IP via dhcp but no network connectivity so I think there are issues with Linux drivers or kernel. I just ordered a SolarFlare SFN6122F which TrueNAS reports works (see TrueNAS resources: 10 Gig Networking Primer), if it does, then I’ll be returning this.‘lspci -vvxnn’ below:Ethernet controller [0200]: Intel Corporation 82599ES 10-Gigabit SFI/SFP+ Network Connection [8086:10fb] (rev 01) Subsystem: Beijing Sinead Technology Co., Ltd. 82599ES 10-Gigabit SFI/SFP+ Network Connection [1dcf:030a] Control: I/O+ Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B- DisINTx+ Status: Cap+ 66MHz- UDF- FastB2B- ParErr- DEVSEL=fast >TAbort- SERR- Latency: 0, Cache Line Size: 64 bytes Interrupt: pin A routed to IRQ 16 IOMMU group: 5 Region 0: Memory at 84180000 (32-bit, non-prefetchable) [size=512K] Region 2: I/O ports at 3020 [size=32] Region 3: Memory at 84204000 (32-bit, non-prefetchable) [size=16K] Expansion ROM at 84100000 [disabled] [size=512K] Capabilities: [40] Power Management version 3 Flags: PMEClk- DSI+ D1- D2- AuxCurrent=0mA PME(D0+,D1-,D2-,D3hot+,D3cold-) Status: D0 NoSoftRst- PME-Enable- DSel=0 DScale=1 PME- Capabilities: [50] MSI: Enable- Count=1/1 Maskable+ 64bit+ Address: 0000000000000000 Data: 0000 Masking: 00000000 Pending: 00000000 Capabilities: [70] MSI-X: Enable+ Count=64 Masked- Vector table: BAR=3 offset=00000000 PBA: BAR=3 offset=00002000 Capabilities: [a0] Express (v2) Endpoint, MSI 00 DevCap: MaxPayload 512 bytes, PhantFunc 0, Latency L0s ExtTag- AttnBtn- AttnInd- PwrInd- RBE+ FLReset+ SlotPowerLimit 0W DevCtl: CorrErr+ NonFatalErr+ FatalErr+ UnsupReq+ RlxdOrd+ ExtTag- PhantFunc- AuxPwr- NoSnoop+ FLReset- MaxPayload 256 bytes, MaxReadReq 512 bytes DevSta: CorrErr+ NonFatalErr- FatalErr- UnsupReq+ AuxPwr- TransPend- LnkCap: Port #0, Speed 5GT/s, Width x8, ASPM L0s, Exit Latency L0s unlimited ClockPM- Surprise- LLActRep- BwNot- ASPMOptComp- LnkCtl: ASPM Disabled; RCB 64 bytes, Disabled- CommClk+ ExtSynch- ClockPM- AutWidDis- BWInt- AutBWInt- LnkSta: Speed 5GT/s, Width x4 (downgraded) TrErr- Train- SlotClk+ DLActive- BWMgmt- ABWMgmt- DevCap2: Completion Timeout: Range ABCD, TimeoutDis+ NROPrPrP- LTR- 10BitTagComp- 10BitTagReq- OBFF Not Supported, ExtFmt- EETLPPrefix- EmergencyPowerReduction Not Supported, EmergencyPowerReductionInit- FRS- TPHComp- ExtTPHComp- AtomicOpsCap: 32bit- 64bit- 128bitCAS- DevCtl2: Completion Timeout: 50us to 50ms, TimeoutDis- LTR- 10BitTagReq- OBFF Disabled, AtomicOpsCtl: ReqEn- LnkCtl2: Target Link Speed: 5GT/s, EnterCompliance- SpeedDis- Transmit Margin: Normal Operating Range, EnterModifiedCompliance- ComplianceSOS- Compliance Preset/De-emphasis: -6dB de-emphasis, 0dB preshoot LnkSta2: Current De-emphasis Level: -6dB, EqualizationComplete- EqualizationPhase1- EqualizationPhase2- EqualizationPhase3- LinkEqualizationRequest- Retimer- 2Retimers- CrosslinkRes: unsupported Capabilities: [e0] Vital Product Data Unknown small resource type 06, will not decode more.

l'ho installata su pfsense per collegarlo ad uno switch mikrotik in 10G. Il sistema l'ha visto senza nessun problema e le performance sono ottime. La consiglio per la sua facilità d'uso e per il prezzo.

To be fair I was a really disappointed when this card turned up. Considering how much it cost the heat sink was quite loose and wobbled about. I tried to straighten it up but it kept reverting back to its wonky state. There's a couple of plastic pegs on opposite corners of the heatsink, held in place with springs, but it looks like one of the springs was weaker than the other one and compressed fully causing the issue. Perhaps my card was faulty but this sort of thing should be picked up in QA.The card seemed to work and was detected fine after installing the Intel drivers from their website. This also leveraged the extra functionality provided by this card's chipset such as VLANs, Link Aggregation etc. so it clearly works and appears to be a genuine Intel chip.However, the heatsink got incredibly hot after only a few minutes use. I just didn't have much confidence in the heatsink doing a good job of dissipating heat, or in the plastic pins holding it on top of a chip that clearly gets really hot.If you are looking for a Dual port 10GbE RJ45 card I think there are better quality options out there.Pros:- Appears to be a genuine Intel chip- Works with Intel drivers to leverage advanced functionality such as VLANs, Link Aggregation etc.- Comes with low profile bracketCons:- Expensive- Really poor build quality on the heatsink and installation- Runs very hot

Arrived within estimate and product as described.For those interested, these seem to ship with SFP vendor locking disabled, so non-Intel SFP should work.

Worked perfectly how I needed didn't even need a driver
