DDR2 800 desktop memory kit

This 8 GB kit contains four 2 GB unbuffered non-ECC UDIMM modules rated for DDR2-800 operation. It is intended for older desktop platforms that still use DDR2 technology and have four available memory slots.

Green PCB unbuffered modules

The modules feature a green printed circuit board and standard UDIMM form factor for direct installation into desktop DIMM sockets. Unbuffered design means they connect straight to the memory controller without a register, which is the typical arrangement for consumer desktop boards of that era.

800 MT/s DDR2 speed rating

The kit runs at the DDR2-800 (PC2-6400) data rate, which is the single specification that determines whether your motherboard and chipset can use these modules at their rated frequency.

Questions about this item

What DDR2 speed and PC rating does this kit run at?

The four modules operate at DDR2-800 with a PC2-6400 rating, so the memory bus tops out at 800 MT/s and 6400 MB/s bandwidth per channel.

What physical slot type and module count are required?

Four standard 240-pin DDR2 UDIMM slots are needed; the kit supplies four 2 GB sticks that must occupy all slots for the full 8 GB capacity.

How are the sticks installed and what step is often missed?

Power off the PC, open the case, align each notch with the slot key, press firmly until both retention clips snap shut, then power on — skipping the power-off step is the common mistake.
