Cheapest Corsair RAM ranked by price per GB

Corsair RAM: Vengeance, Dominator and the value picks

Corsair is the best-known memory brand in the UK and one of the largest sellers on Amazon.co.uk, which is why this page usually has the widest choice of any brand page. The 214 Corsair kits above are ranked by price per gigabyte, from £2.98/GB to £60.67/GB with a median of £14.63/GB; the cheapest kit right now is CORSAIR VENGEANCE LPX DDR4 RAM 16GB (2x8GB) Up to 3200MHz CL16 Intel X… at £47.68. Speeds run from 1,066 to 6,800MHz.

The Corsair ranges explained

• Vengeance LPX (DDR4): the low-profile workhorse at 2666 to 3600MHz, clears any cooler, and is normally the cheapest Corsair kit per gigabyte. Vengeance RGB Pro is the same idea with lighting.
• Vengeance and Vengeance RGB (DDR5): the mainstream DDR5 line at 5200 to 7200MT/s with XMP 3.0 and AMD EXPO versions; the plain Vengeance is compact, the RGB adds height.
• Dominator Platinum RGB and Dominator Titanium: the premium tier, hand-screened chips, tall heatspreaders and the highest rated speeds. You pay for the binning and the look; at the same speed and latency a Vengeance kit performs the same.
• Vengeance SO-DIMM and Mac Memory: laptop modules on the laptop page, and the Mac Memory kits qualified for 2017 to 2020 iMacs and the 2018 Mac mini on the Mac page.
• Value Select: plain green PCB modules for office machines and older DDR3 systems.

What to buy

For a DDR4 build, Vengeance LPX 2x8GB or 2x16GB at 3200 CL16 (or 3600 CL18 on Ryzen) is the standard recommendation and often the cheapest on the page. For AM5 or current Intel, Vengeance DDR5 6000 CL30 with the EXPO or XMP profile matching your CPU is the sweet spot; the 32GB and 64GB pages let you compare Corsair against other brands at the same size. Corsair does not make its own DRAM: the chips are Samsung, SK hynix or Micron, so the difference between Corsair and, say, Crucial or Kingston at the same spec is the heatspreader, the software (iCUE for RGB) and the lifetime warranty, not speed.

Corsair kits are very common in Amazon Warehouse returns, and memory is one of the safest used categories because it either passes a memory test or it does not. A Warehouse Vengeance kit with a price-drop badge in the table is frequently the best value Corsair on the page; check the product page's price history to confirm it is cheap by the year's standards and not just down from a 2026 spike.
