Dell G5 5090 8GB DDR4 Module

This 288-pin UDIMM adds 8GB of DDR4 memory to a Dell G5 5090 desktop. It operates at 2666MHz with a CL19 latency and runs at the standard 1.2V. The unbuffered, non-ECC design matches the original system specification for a straightforward upgrade.

Suits owners of the Dell G5 5090 needing a single

Builders assembling a different platform or requiring ECC registered modules should look elsewhere. Systems that need higher density per slot or multi-kit configurations are not addressed by this single module.

JEDEC PC4-21300 2666MHz speed rating

The module conforms to the JEDEC standard at 2666MHz and is backward compatible with 2400MHz and 2133MHz bus speeds. This rating determines whether the memory will run at the intended frequency in the Dell G5 5090.

Questions about this item

What motherboard slot does this 288-pin UDIMM require?

It fits a standard desktop DDR4 DIMM slot with 288 pins; the Dell G5 5090 has four such slots.

Will it run at 2666MHz if my current sticks are 2400MHz?

The module is backward compatible with 2133MHz and 2400MHz, so it will operate at the speed of the slowest installed memory.

How do I verify the CL19 timing is active after install?

Open Task Manager or CPU-Z and confirm the memory runs at 2666MHz with a CAS latency of 19.
