Lenovo ThinkSystem 64GB DDR4 2933MT/s 2Rx4 RDIMM-A

At the top of its family, the Lenovo ThinkSystem 4ZC7A08744 provides 64GB per module as a 2Rx4 RDIMM-A. It runs DDR4 at 2933MT/s, 1.2V, with ECC, and its feature code is B7MW.

The listed systems are the Lenovo ThinkSystem SR635 and SR655. High-capacity modules let a single-socket server reach a large memory footprint while leaving slots free, which is useful for database caches and dense virtual machine hosts.

Compare the price per gigabyte against smaller modules when you plan the build: sometimes fewer large DIMMs cost less overall once the slot count is considered.

We can supply the 4ZC7A08744 refurbished with 1 year or 3 years of warranty, or used with a 90 day warranty. No new offer is listed. Tell us the quantity and we will reply with pricing and availability.
