24-core Xeon Gold 6542Y for dual-socket servers

The Intel Xeon Gold 6542Y is a 24-core, 48-thread server processor built on a 10 nm process. It runs at a 2.9 GHz base frequency and reaches a 4.1 GHz max turbo frequency. The chip provides 60 MB of L3 cache and a 250 W thermal design power for sustained multi-threaded workloads in dual-socket platforms.

Suited for memory-intensive dual-socket deployments

This processor supports up to 4 TB of memory across eight channels at 5200 MHz, making it suitable for virtualisation hosts, database nodes and compute clusters that need high memory bandwidth. Buyers who need single-socket operation or lower power envelopes should look at other SKUs, as this part is designed for 2S scalability and a 250 W TDP.

80 PCIe 5.0 lanes and 60 MB cache headroom

The 80 lanes of PCI Express 5.0 give ample connectivity for high-speed storage arrays, GPU accelerators and networking adapters without bottlenecks. The 60 MB L3 cache absorbs large working sets in memory-heavy applications. Workloads that exceed 4 TB of system memory or require more than two sockets will need a different processor tier.

Questions about this item

What motherboard socket do I need for the LGA 4677 processor?

You need a server motherboard with an LGA 4677 socket; the processor will not fit any other socket type.

Will the 5.0 PCI Express lanes work with my existing 4.0 expansion cards?

Yes, the 80 PCIe 5.0 lanes are backward compatible, so your 4.0 cards will operate at their rated speed.

How can I confirm the 24 cores and 48 threads are active after installation?

Check the operating system task manager or run lscpu to verify 24 cores and 48 threads are reported.
