4GB DDR4 2666MHz Desktop Module

This 4GB DDR4 module runs at 2666MHz with a CAS latency of CL19 and operates at the standard 1.20V. It is built as a direct compatible replacement for the HP 934253-800 part number in desktop systems.

Unbuffered DIMM Without Heat Spreader

The stick uses a 288-pin DIMM form factor and is unbuffered non-ECC memory. It carries major brand chips but has no heat spreader, so it fits tight spaces and works with standard CPU coolers without clearance issues.

DDR4 2666MHz Speed and Voltage Limits

The DDR4 interface tops out at the 2666MHz tested frequency and PC4-21300 bandwidth rating. The fixed 1.20V voltage and CL19 timing define the performance ceiling, so the module will not exceed these specifications in any system.

Questions about this item

What DDR4 standard and speed does the 934253-800 module run at?

It runs at DDR4 2666, rated as PC4-21300 with a tested frequency of 2666 MHz.

Which physical slot and pin count does this DIMM need?

It uses a standard 288-pin DDR4 DIMM slot on a desktop motherboard.

How is the module installed and what step is often missed?

Align the notch with the slot key, press down firmly until both side clips click; the step often missed is not pushing hard enough to fully seat both clips.
