G.Skill Ripjaws M5 RGB F5-6000J3040F16GX2-RM5RK

True latency is CAS latency divided by half the transfer rate: 30 / (6000 / 2) x 1000 = 10ns. That is tighter than 54% of the desktop DDR5 kits we list. The full timings are 30-40-40-96. tRCD and tRP sit 10 clocks above the CAS latency, so compare full timings, not just CL, against other kits at this speed.

Any desktop board with DDR5 slots takes it, including AMD AM5 (600 and 800 series) and Intel 600, 700 and 800 series. DDR4 boards will not accept it; the key notch sits in a different spot. On AM5, 6000MT/s keeps the memory controller at a 1:1 ratio, which is why it is the go-to speed for Ryzen 7000 and 9000. It has an Intel XMP 3.0 profile only. Most AM5 boards can still load XMP, but kits with EXPO are validated for AMD. Out of the box it runs at the JEDEC default of 4800MT/s and 1.1V. Enable the XMP 3.0 profile in the BIOS to reach 6000MT/s.

It ships as two 16GB sticks, one per channel, the layout every consumer board runs best with. Plan capacity now: adding a second kit for four DDR5 sticks usually forces the memory down well below its rated speed. At 32GB you have room for gaming, streaming and editing without running short.

It has RGB lighting on a black heat spreader. At 41mm tall, check your air cooler's RAM clearance before buying. The memory chips are not disclosed. That only matters if you plan to tighten timings manually. Warranty: limited lifetime.

It scores 8.3 out of 10 on our DDR5 Speed Score, which weighs transfer rate and true latency against every other DDR5 kit we list. Do not compare it with DDR4 scores.
