Targeted Lenovo upgrade

This 32GB kit uses two 16GB DDR4 DIMMs validated for Lenovo IdeaCentre 510 and T540 desktops. Unbuffered non-ECC modules run at 2666MHz with CL19 timing at the standard 1.2V. The matched pair fills both available slots so the system reaches its 32GB maximum without mixing speeds.

Drop-in installation

Each stick fits a standard 288-pin DDR4 slot and requires no heat spreader or extra clearance. Because the kit occupies both sockets, no further memory can be added unless modules are removed. All installed memory will operate at the slowest module or processor limit, so matching pairs keep performance consistent.

Steady throughput

Continuous workloads run at the rated 2666MHz without throttling because the modules use major-brand chips at JEDEC voltage. Rank organisation is 2Rx8, delivering stable bandwidth for multi-tasking and sustained data processing. Mixed configurations will drop to the lowest common speed, so this matched kit avoids that penalty.

Questions about this item

What is the maximum memory capacity supported by the Lenovo IdeaCentre 510 and T540 models listed?

The supported Lenovo IdeaCentre 510 and T540 models have a maximum memory capacity of 32GB across two DIMM sockets.

Does this DDR4-2666 CL19 kit generate more heat or noise than standard JEDEC modules?

No, these unbuffered non-ECC DIMMs run at the standard 1.20V with no heat spreader, so thermal output and silent operation match baseline DDR4 specifications.

Which CPU architecture or motherboard chipset is required to run this 2Rx8 DDR4-2666 kit at its rated speed?

The kit is validated for the Lenovo IdeaCentre 510-15ICK, 510A-15ARR, 510A-15ICB, 510A-15ICK, T540-15AMA-G and T540-15ICB G platforms.
