8 GB DDR5 module for HP OMEN 40L GT21

This single 8 GB DDR5 5200 UDIMM is built specifically for the HP OMEN 40L GT21 series including the 1000m 1005m 1355st 1455se and 2000t models. It targets owners of those desktops who need a straightforward capacity increase. The module follows JEDEC standard timings and voltage for broad compatibility within the supported platforms.

Unbuffered non ECC design

The stick uses a 1Rx8 unbuffered non ECC organisation and runs at 1.1 V without a heat spreader. Its plain 288 pin DDR5 edge connector fits the standard DIMM slots on the listed OMEN motherboards. The low profile bare PCB allows installation even when CPU coolers or chassis baffles sit close to the memory sockets.

DDR5 5200 CL42 speed grade decides fit

The module operates at DDR5 5200 PC5 41600 with a CAS latency of 42. That speed grade must match the memory controller capabilities of the target OMEN 40L GT21 systems for stable operation. Buyers whose HP OMEN desktop is not one of the five listed model numbers cannot rely on this module working correctly.

商品問答

What DDR5 speed and CAS latency does the OWC 8GB module run at?

The module runs at DDR5 5200 (PC5-41600) with CL42 latency at the standard 1.1 V JEDEC voltage.

Will this 288-pin UDIMM fit inside the HP OMEN 40L GT21 chassis?

Yes — it is a standard 288-pin unbuffered non-ECC UDIMM without a heat spreader, designed for the OMEN 40L GT21-1000m, 1005m, 1355st, 1455se and 2000t.

How do I install the module and what step do people often miss?

Power off, open the case, align the notch with the slot key, press firmly until both retention clips click; the step often missed is fully seating both clips so the module cannot tilt.
