G.SKILL Ripjaws S5 48GB ( 48GBx1 ) 5200MHz DDR5 RAM ( CL40 )

The G.Skill Ripjaws S5 48GB DDR5 desktop memory module (model F5-5200J4040A48GX1-RS5K) is a single-stick, 48GB DDR5 kit engineered for enthusiast-class desktop builds that demand generous capacity without RGB overhead. Running at a tested XMP speed of 5200 MT/s with primary timings of 40-40-40-83 and a tested voltage of 1.10V, it delivers a strong combination of bandwidth and stability straight from the BIOS once the Intel XMP 3.0 profile is enabled. Built around hand-screened DDR5 ICs that have passed G.Skill’s internal validation process, each Ripjaws S5 module is designed to strike a practical balance between outright performance, broad motherboard compatibility, and day-to-day stability. The minimalist matte-black aluminium heatspreader draws inspiration from classic racing-stripe aesthetics and keeps the thermal footprint modest. At just 33mm in height, the Ripjaws S5 fits comfortably in compact mid-tower and small-form-factor cases and leaves clearance for most tower CPU coolers. On the compatibility side, the module ships as an unbuffered, non-ECC DIMM — the standard configuration for consumer Intel Core platforms. Its default SPD speed is 4800 MT/s at 1.10V, so it will always boot safely even on motherboards that do not yet have an updated BIOS. Enabling XMP 3.0 in the BIOS unlocks the full 5200 MT/s rated speed, subject to your motherboard and CPU’s maximum supported frequency. The 48GB single-stick configuration is particularly valuable for users who want to leave a second DIMM slot free for a future upgrade to dual-channel, or for workloads — video editing, large virtual machines, data analysis — that benefit from a larger single-module capacity than the traditional 32GB ceiling.
