GLOTRENDS LE8245F quad-port PCIe card with four RJ45 jacks, low-profile bracket

GLOTRENDS

GLOTRENDS LE8245F 4-port network card 2×2.5Gbps 2×1Gbps PCIe 2.0 x2

SKU CH-Y5ME-4MDRF MPN LE8245F

Adds four RJ45 Ethernet ports — two at 2.5Gbps and two at 1Gbps — via a PCIe 2.0 x2 slot using four RTL8125BG chips

Ports 2-port(1Gbps) + 2-port(2.5Gbps)

Struck-through versions exist but are not stocked here.

  • Four Ethernet ports on a single PCIe 2.0 x2 card
  • Two ports reach 2.5 Gbps while two run at 1 Gbps
  • 4 Gbps total downstream bandwidth across all four ports
  • Broad OS support including Windows, Linux, macOS and major hypervisors
  • Four RTL8125BG chips with LED indicators for link speed

Four-port mixed-speed NIC

The GLOTRENDS LE8245F adds four wired Ethernet connections through a single PCI Express 2.0 x2 slot. Two RJ45 ports operate at up to 2.5Gbps and two at up to 1Gbps, making it suited for servers, NAS appliances, soft routers and firewalls that need extra LAN interfaces. It uses four RTL8125BG controllers and is compatible with Windows, Linux, macOS and common virtualisation platforms such as VMware ESXi and Proxmox.

PCIe 2.0 x2 bandwidth ceiling

The x2 link provides 6.4Gbps of downstream bandwidth, so only two ports can run at 2.5Gbps simultaneously while the remaining two are limited to 1Gbps. The card negotiates speeds automatically and includes LED indicators that show green for 2.5Gbps links and yellow for 1Gbps links. Driver installation may be required on some operating systems or newer hypervisor releases to achieve full performance.

Capacity and headroom

The adapter comfortably handles typical multi-gigabit LAN workloads such as aggregated NAS traffic, virtual-machine networking and firewall throughput within the 6.4Gbps aggregate limit. It runs out of headroom when all four ports are pushed to 2.5Gbps at the same time, a scenario the PCIe 2.0 x2 interface cannot sustain. For that level of concurrent throughput a wider PCIe link or additional cards would be necessary.

Questions about this item

Should I use the two 2.5Gbps ports or the two 1Gbps ports for my fastest links?

Connect your highest-throughput devices to the two 2.5Gbps ports; the other two ports are limited to 1000Mbps because the PCIe 2.0 x2 link caps total bandwidth at 6.4Gbps.

Will I actually see 2.5Gbps throughput on each of the two fast ports at the same time?

Yes, both 2.5Gbps ports can run at 2500Mbps simultaneously; the 6.4Gbps PCIe 2.0 x2 ceiling allows two full 2.5Gbps streams plus the two 1Gbps ports.

My motherboard only has a PCIe 2.0 x4 slot — will that bottleneck the card?

The card uses a PCIe 2.0 x2 electrical interface, so a x4 slot provides more than enough bandwidth; the 6.4Gbps downstream limit is set by the x2 link, not the slot width.
