How these alternatives compare
Corsair Vengeance LPX 32GB DDR4 2666MHz C16
This option doubles your capacity to 32GB while keeping the same 2666MHz speed and CL16 latency. It uses a two-module configuration, which leaves two DIMM slots free for future upgrades. The height drops to 0.4 inches, making it even more compact than the original. You get the same low-profile aluminum heatspreader design, ensuring compatibility with large air coolers. The color is red, which may not match a black system. Choose this if you need more memory for video editing or virtualization without sacrificing the slim profile that fits tight cases.
G.SKILL Ripjaws 8GB DDR4 2400MHz SODIMM
This kit targets laptops rather than desktops. It uses SO-DIMM form factor, so it will not fit standard desktop motherboards. The capacity is only 8GB, which is half the size of the original kit. Speed is 2400MHz, which is slower than the 2666MHz standard. Latency remains CL16, maintaining tight timing for its speed class. It operates at 1.2V, matching modern power standards. Pick this only if you are upgrading a compatible laptop or mini PC. It is a budget-friendly single-module solution for portable systems needing a straightforward capacity boost.
Patriot Signature Line 16GB 2666MHz DDR4 RAM
This kit offers the same 16GB capacity and 2666MHz speed as the original but uses a two-module configuration instead of four. This leaves two motherboard slots empty for expansion. The height is 1.22 inches, which is taller than the original 0.8 inches. It may not fit under very large CPU coolers. It lacks the aluminum heatspreader found on the Corsair model, relying on standard PCB design. It is a solid choice for standard desktop builds where slot availability matters more than compact height. It provides dual-channel performance at a competitive specification level.
Timetec 16GB DDR4 2666MHz UDIMM
This single-module 16GB stick saves two motherboard slots compared to the four-module original kit. It runs at 2666MHz but has a higher CL19 latency, which is slightly slower than the CL16 timing of the Corsair kit. It operates at standard 1.2V and is non-ECC. The gold color is distinct from the black original. It is ideal if you need a single stick for capacity expansion while leaving slots open. The trade-off is higher latency and a different aesthetic. It is a practical option for users prioritizing slot availability over tight timings.
TEAMGROUP Elite 8GB DDR4 2666MHz UDIMM RAM
This is a single 8GB module, offering half the capacity of the original 16GB kit. It runs at 2666MHz with CL19 latency, which is looser than the original CL16. It is a standard UDIMM for desktops, not a low-profile kit. The height is 1.97 inches, which is taller than the original. It operates at 1.2V and is non-ECC. Choose this if you need a single stick for a basic upgrade or if you already have an 8GB stick installed. It is a budget-friendly entry point for desktop memory expansion without the complexity of a four-module kit.
Timetec 16GB DDR4 2666MHz SODIMM RAM
This is a 16GB single-module SO-DIMM, designed for laptops and mini PCs, not desktops. It runs at 2666MHz with CL19 latency, which is slower than the original desktop kit. It operates at 1.2V and is non-ECC. The black color matches the original aesthetic, but the form factor is incompatible with standard desktop motherboards. It is a direct alternative for users with compatible portable systems who need 16GB in a single stick. It provides a straightforward upgrade path for laptops without requiring a full kit replacement.
