Cut load times. Accelerate demanding applications. And spend less time waiting on your system and more time getting work done. Crucial ECC UDIMMs enable you to maximize the performance capability of your CPUs for a faster, more responsive system

Crucial ECC UDIMMs contain error correction code (ECC). ECC parity helps detect and correct single-bit Memory errors, which can cause sudden shutdowns, file corruption, or data loss. Help prevent costly downtimes with Crucial ECC UDIMMs, which ensure a higher level of data integrity

Crucial ECC UDIMMs are available in DDR to DDR4 memory technology, and select modules are also available in the very low profile (vlp) form factor. Measuring just 18.75mm tall, Crucial vlp ECC UDIMMs are 40% shorter than standard ECC UDIMMs and facilitate better airflow in space-constrained, systems such as micro servers, routers, and switches
