Desktop Memory
Desktop Memory covers unbuffered DIMMs for towers, small-form-factor PCs and workstations that don't use registered memory. Most current listings are DDR5: Kingston FURY Beast and FURY RGB kits rated from DDR5-5200 to DDR5-6000, Kingston ValueRAM and Samsung DDR5-5600 modules, and Lenovo, HP and Dell part numbers for business desktops. DDR4-3200 modules for desktops from the last several years are listed alongside DDR2 sticks for much older machines.

Upgrading desktop memory
DDR4 or DDR5
Both are 288-pin modules, but the key notch sits in a different place, so each fits only a board built for its generation. The motherboard or system manual names which one you have.
Rated speed profiles
Enthusiast kits like FURY Beast reach their rated speed through an XMP (Intel) or EXPO (AMD) profile enabled in the BIOS. Without it, they run at the standard JEDEC speed.
Kits and channels
Modules in a kit are matched to run together. Install them in the paired slots the motherboard manual marks for dual-channel operation.
OEM part numbers
HP, Dell and Lenovo memory carries the part number listed in that system's parts list, which is the simplest route for business desktops.

Frequently asked questions
What do the numbers in a desktop memory listing mean?
In "DDR5-5600 UDIMM 1Rx8 CL46", 5600 is the data rate in megatransfers per second, UDIMM means unbuffered, 1Rx8 means one rank built from 8-bit-wide chips, and CL46 is the CAS latency in clock cycles.
Is DDR5's on-die ECC the same as ECC memory?
No. On-die ECC corrects errors inside each DRAM chip and is built into every DDR5 module. Full ECC modules add extra chips that protect data on its way to the memory controller, and need a platform that supports ECC.
Can I add one new module to the memory I already have?
Usually, if it's the same generation and type. All modules then run at the speed and timings of the slowest one, and matching the existing module's capacity keeps both channels evenly loaded.
