Compatible HP Slimline upgrade

This 8GB DDR4 module is built for the HP Slimline 270-p027cb, 270-p036 and 270-p043w desktops. It uses a 288-pin UDIMM form factor and runs at 1.2V without ECC or buffering. The CL17 latency and 2400MHz speed match the JEDEC standard for a warranty-safe installation.

Steady multitasking behaviour

Under sustained workloads the unbuffered design keeps latency predictable at CL17 while the 1.2V operation limits thermal buildup. Backward compatibility with 2133MHz systems allows the module to clock down without instability. The dual-rank 2Rx8 organisation helps maintain throughput when several applications share the memory bus.

Replaces factory 4GB or 8GB sticks

Swapping a single 4GB DIMM for this 8GB unit doubles capacity for larger files and more concurrent browser tabs. The jump is worthwhile when the system currently hits the memory ceiling during everyday multitasking. It is not for users who need ECC protection or registered DIMMs for server workloads.

Questions about this item

Does the 1.2V DDR4 module run hot or noisy inside the HP Slimline 270-p027cb?

The unbuffered 8 GB stick operates at standard 1.2 V with no heat spreader, so it adds negligible heat and makes no noise during all-day use.

What must the HP Slimline 270-p036 already have for this 288-pin UDIMM to work?

The desktop needs a free DDR4 DIMM slot that accepts 288-pin unbuffered non-ECC memory at 2400 MHz or 2133 MHz.

Will this CL17 2400 MHz kit downclock reliably beside existing 2133 MHz RAM in the 270-p043w?

Yes, the module is backward compatible with 2133 MHz systems and will run at the lower speed alongside older sticks.
