Computer Memory Solutions CM1024642666DIMM 8GB DDR4 2666MHz CL19 2Rx8 1.2V memory upgrade

SKU CH-CJFS-R1P30

An 8 GB DDR4-2666 DIMM built for Dell OptiPlex XE3 SFF and XPS 8930 desktops

  • Capacity8GB
  • Type288-Pin DDR4 SDRAM
  • SpeedDDR4 2666 (PC4 21300)
  • CAS LatencyCL19
  • Timing19-19-19
  • Voltage1.20V
  • 8GB capacity expands system memory for Dell OptiPlex XE3 SFF and XPS 8930
  • DDR4 2666MHz speed matches PC4-21300 specification for responsive performance
  • CL19 CAS latency with 19-19-19 timing delivers stable operation
  • 2V low voltage reduces power draw without heat spreader
  • 288-pin unbuffered non-ECC DIMM fits four available sockets up to 64GB

Compatible Dell Desktop Upgrade

This 8GB DDR4 module is built for Dell OptiPlex XE3 Small Form Factor and XPS 8930 Desktop systems. It targets owners of those specific machines who need a straightforward capacity increase without compatibility guesswork.

Single Stick For Four Slot Boards

The DIMM uses the standard 288-pin DDR4 interface and runs at 1.2V unbuffered, so it drops into any of the four memory sockets on the supported platforms. Adding one stick leaves three slots open for future expansion up to the 64GB system maximum.

Steady Operation At CL19

Rated at 2666MHz with 19-19-19 timings and a 2Rx8 organisation, the module delivers consistent throughput during extended workloads. All installed memory will operate at the slowest module or processor limit, so matching pairs are recommended for peak bandwidth.

Questions about this item

Will the CL19 timing limit bandwidth when the XPS 8930 runs memory-intensive workloads for hours?

The module operates at DDR4 2666 with CL19 19-19-19 timings; sustained throughput is capped by that latency figure and the CPU's memory controller.

Does the unbuffered 1.2 V design add noticeable heat or fan noise inside a Dell OptiPlex XE3 SFF during all-day operation?

At 1.20 V with no heat spreader the sticks run cool; the SFF chassis fans typically stay at idle speed even under continuous load.

Must the OptiPlex XE3 SFF or XPS 8930 already have a 64-bit OS installed for this 8 GB DIMM to be recognised?

Yes — a 64-bit operating system is required to address more than 4 GB, so the full 8 GB capacity will only be usable with one already present.
