What is the highest core count CPU for the Dell R540?

The 2.00Ghz Gold 6138T 20-Core 125W is the highest core count processor we list for the Dell R540, at 20 cores. Higher core counts suit virtualization and container hosts where total thread count matters more than per-core speed.

What is the fastest processor for the Dell R540?

By clock speed, the 2.30Ghz Gold 5218 16-Core 125W tops the list for the Dell R540 at 3.9GHz. Fewer, faster cores generally win for databases and applications licensed per core.

What CPU socket does the Dell R540 use?

Processors for the Dell R540 use the LGA 3647 socket. A processor must match both the socket and the chassis generation to work, which is why this page lists only verified-compatible parts.

What TDP processors does the Dell R540 support?

Compatible processors for the Dell R540 range from 70W to 125W TDP. Higher TDP parts run hotter and may require specific heatsinks or fan configurations — contact our team if you are unsure what your chassis is configured for.

Can I buy the Dell R540 with these processors already installed?

Yes. Configure a Dell R540 to order and pick your processors, memory, storage and controllers in one build, and we will assemble, test and ship it configured. Every system carries a one year warranty, extendable to five.

Are used and refurbished processors reliable?

Server processors have no moving parts and are among the most durable components in a system. Every CPU we sell for the Dell R540 is tested before it ships and backed by the same one year warranty as our systems.
