How should you compare Corsair kits?
Corsair is the biggest brand in our UK data, so the list is long, and the names can blur. The line is in the kit title: Vengeance, with RGB and LPX versions, and Dominator, which includes Titanium and Platinum models. Ignore the line name and read three things: the type (DDR5 or DDR4), the speed and CL, and the price per GB.
For a new AMD AM5 build, the target is the same as for any brand: a 32GB DDR5 kit at 6000 MT/s and CL30, switched on with EXPO. The cheapest Corsair 32GB DDR5 desktop kit this week is £419.99 at Overclockers UK. See 32GB RAM prices for the same size across all brands.
Does the heatsink or RGB change anything?
Not the memory speed. What the kit looks like and how tall it is are separate from the numbers on the label, so check the module height against your CPU cooler before you order, and do not pay extra for lighting you do not want.
If the price per GB column shows a Dominator kit well above a Vengeance kit of the same speed and latency, the difference is design and brand line, not performance on the label.
XMP, EXPO and your board
Corsair kit titles often say XMP (Intel) or EXPO (AMD). Both are overclocking profiles that you switch on in the BIOS, and both vendors treat overclocking as outside the official spec. Without the profile, a fast kit runs at a slower default. Prices here include VAT, and delivery is extra.
DDR5 and DDR4 Corsair kits look alike. Your motherboard takes one type only, so check the manual before you order.
