The HP DDR4 8GB DIMMMHz is a desktop memory module for HP desktop PCs and compatible systems running DDR4-2400 platforms. It provides an upgrade option for older HP EliteDesk and ProDesk models that do not support the higher DDR4-2666 speed.
HP DDR4 8GB DIMM — Desktop Memory for DDR4-2400 Platforms
This DIMM is rated at 2400MHz, correct for 7th and 8th Gen HP desktop platforms that support DDR4-2400. Installing a DDR4-2666 module in a DDR4-2400 platform results in the module running at 2400MHz. the reverse—installing this 2400MHz module in a 2666MHz platform—also results in the module running at 2400MHz (the lower supported speed). For maximum platform performance, matching the DIMM speed to the platform’s native DDR4 specification is recommended. Genuine HP memory ensures compatibility with HP’s desktop qualification testing.

Memory Upgrades for Older HP Desktops in South Africa
South African businesses with HP EliteDesk 800 G3/G4 or ProDesk 400 G4/G5 at 8GB will find this 2400MHz DIMM the correct upgrade to extend device life. Upgrading from 8GB to 16GB on an office productivity PC improves multitasking and reduces the need to replace the device solely due to memory pressure. Genuine HP DIMMs at the correct speed specification are the recommended approach for these upgrades. Browse desktop memory in the Memory &. Storage >. RAM section at Briggi Tech.
DDR4-2400 vs DDR4-2666 Compatibility
DDR4 modules are generally backward-compatible: a 2666MHz DIMM in a 2400MHz platform runs at 2400MHz. The difference in real-world office application performance between 2400MHz and 2666MHz is minimal. Purchasing the correct speed for the target platform avoids potential JEDEC timing issues on older HP BIOS versions.
HP also offers an 8GB DDR4-2666 DIMM variant for desktop platforms that support the higher speed. For HP desktops from the 8th Gen Intel Core era onwards that natively support DDR4-2666, the 2666MHz DIMM is the correct specification. The 2400MHz DIMM reviewed here is the correct choice specifically for 7th Gen and earlier platforms where DDR4-2400 is the platform-native speed.
