8 GB DDR4 DIMM for Lenovo IdeaCentre

This 8 GB DDR4-2666 module is built as a direct-fit upgrade for select Lenovo IdeaCentre 510 and T540 desktops. It uses a standard 288-pin unbuffered layout running at 1.2 V with CL19 timing. The single stick adds capacity without requiring configuration changes.

Replaces slower or smaller DDR4 sticks

If the system currently runs at a lower DDR4 speed or has only 4 GB installed, this module raises the ceiling to the platform’s supported 2666 MT/s rate. The upgrade is worth it when the board has a free slot or when replacing a mismatched stick that forces the whole kit down to a slower common speed.

Suits owners of the listed IdeaCentre models

Buyers with compatible Lenovo IdeaCentre 510-15ICK, 510A-15ARR, 510A-15ICB, 510A-15ICK, T540-15AMA-G or T540-15ICB G desktops can install this module with confidence. Builders needing ECC, registered DIMMs, higher capacities per stick, or memory for a different platform should look elsewhere.

Questions about this item

Will the 288-pin DDR4 DIMM fit the two memory slots in my Lenovo IdeaCentre 510 or T540?

Yes, the module uses the standard 288-pin DDR4 DIMM form factor that matches the two slots in those IdeaCentre models.

Do I need to install the stick in a specific slot or pair it with another module for the system to recognise the 8 GB at 2666 MHz?

Insert the DIMM into either slot; the system will run at 2666 MHz, but adding a second identical stick enables dual-channel mode for higher bandwidth.

Is there any heat spreader or fan header I must maintain on this 1.2 V unbuffered module over its lifetime?

No, the stick has no heat spreader and draws only 1.2 V, so it requires no active cooling or periodic maintenance beyond keeping the slot dust-free.
