The G.Skill Ripjaws S5 48GB (48GBx1) DDR5 5200MHz CL40 RAM is a single-module desktop memory upgrade built on the DDR5 standard. It is supplied as one 48GB DIMM rather than a matched kit, so it suits builders who want a large block of memory in a single channel, or who plan to add capacity while keeping a slot free for later expansion. Out of the box the module runs at the JEDEC default of 4800 MT/s at 1.10V. Enabling the Intel XMP 3.0 profile in a compatible BIOS steps it up to the tested 5200 MT/s speed, with rated timings of 40-40-40-83 (CL40) at 1.10V. Because mixing memory kits can cause instability, G.Skill recommends running modules from a single matched set. As an unbuffered, non-ECC UDIMM, this module targets mainstream desktop platforms rather than servers or workstations that need registered ECC memory. Typical use cases include heavy multitasking, content creation, photo and video editing, running virtual machines and everyday gaming, where 48GB of memory reduces reliance on disk paging. Verifiable specifications: Memory type DDR5; Capacity 48GB (1 x 48GB), single-channel module; Tested speed 5200 MT/s with XMP; Default SPD speed 4800 MT/s; Tested timings 40-40-40-83, CL40; Tested and default voltage 1.10V; Form factor unbuffered UDIMM; Error correction None (non-ECC); Intel XMP 3.0 ready; No fan or active cooling; Model F5-5200J4040A48GX1-RS5K; Warranty Limited Lifetime per G.Skill. Reaching the rated XMP speed depends on motherboard and CPU compatibility

| Additional | Do not mix memory kits. Memory kits are sold in matched kits that are designed to run together as a set. Mixing memory kits will result in stability issues or system failure. Memory kits that are "Intel XMP 3.0 Ready" only includes XMP, and memory kits that are "AMD EXPO Profile Ready" only includes EXPO. Prior to enabling XMP or EXPO, memory kits will boot at default BIOS settings with compatible hardware. For memory kits with XMP or EXPO, enable XMP/EXPO/DOCP/A-XMP profile in BIOS to reach the rated potential XMP or EXPO overclock speed of the memory kit, subject to the use of compatible hardware. Please refer to the "How to Enable XMP/EXPO" guide. Reaching the rated XMP/EXPO overclock speed and system stability will depend on the compatibility and capability of the motherboard and CPU used. Usage in any manner inconsistent with manufacturer specifications, warnings, designs, or recommendations will result in lower speeds, system instability, or damage to the system or its components. Memory module height can be found in the FAQ, under the question "How tall are the memory modules?"
