Memory

Memory modules for desktop PCs, laptops and servers, mostly DDR4 and DDR5, with older DDR3 and DDR2 for upgrades. Our range has over 3,800 products, including G.SKILL, Kingston, Corsair and Crucial modules as well as Dell, Lenovo and HP memory.

It suits anyone adding RAM to an existing computer, building a gaming PC or maintaining a server.

How to choose RAM

Module format. Laptops usually need SO-DIMM modules, while desktop PCs and servers use full-size DIMMs. Our range includes 288-pin and 240-pin DIMMs and several SO-DIMM types (260, 262, 204 and 200 pins), so check which format your device takes before ordering.

Memory standard. DDR3, DDR4 and DDR5 modules are not interchangeable and will not fit a slot built for another standard. Most of our range is DDR4 and DDR5, while DDR3, DDR3L and DDR2 help with older machines. DDR3L runs at a lower voltage, so choose it when the device maker asks for it.

Capacity and kits. 8 or 16 GB is enough for many users, while gaming, video editing and virtual machines call for 32 or 64 GB. Two-module kits such as 2 x 16 GB let the memory run in dual-channel mode, which usually speeds things up. Check how much memory your motherboard or laptop supports first.

Speed and latency. We stock modules from 800 to 5600 MHz, with 3200 and 2666 MHz among the common options. At the same speed, a lower CAS latency means a slightly quicker response, but the processor and motherboard also limit the real speed.

ECC support. ECC modules correct single-bit memory errors and are meant for servers and some workstations. Our range includes both ECC and standard modules, and ordinary desktop PCs usually do not support ECC, so check your processor and motherboard specifications.

Brands in our range

Also in our range: 2-POWER and CoreParts modules.

Frequently asked questions about RAM

How much RAM do I need?

8 or 16 GB is enough for many everyday tasks. Gaming and heavier work often call for 16 or 32 GB, and video editing or virtual machines may need 64 GB. The maximum capacity is set by your motherboard or laptop.

Can I put DDR4 memory in a DDR5 slot?

No. DDR4 and DDR5 modules have the notch in different positions, so they physically do not fit the other slot, and their electrical specifications differ. Check which standard your motherboard or laptop supports before buying.

Can I mix RAM modules of different brands or speeds?

Often yes, but the safest approach is to use identical modules, ideally from the same kit. If the speeds differ, the memory normally runs at the speed of the slowest module. Modules of the same capacity also help enable dual-channel mode.

What is the difference between DIMM and SO-DIMM?

DIMMs are longer modules for desktop PCs and servers, while SO-DIMMs are shorter and used in laptops and many mini PCs. The two formats cannot be swapped. Our range includes both types.
