8GB DDR4 UDIMM for Lenovo Legion

This 8GB DDR4 2666MHz CL19 UDIMM is built for Lenovo Legion C530-19ICB and C730-19ICO desktops. It runs at 1.2V with a 288-pin unbuffered non-ECC design. The module meets JEDEC PC4-21300 specifications for a direct fit.

Suits owners of listed Legion models only

It fits the two named Lenovo Legion systems that accept DDR4 2666MHz UDIMMs. Builders using laptops, small-form-factor boards, or servers requiring ECC or registered memory cannot use this module. Systems locked to lower maximum speeds or different pin counts are also incompatible.

2666MHz CL19 speed grade decides fit

The module operates at DDR4 2666MHz with CL19 latency at 1.2V. It will down-clock to 2133MHz or 2400MHz if the platform requires it. Verify that your motherboard supports this exact speed and timing combination before purchase.

Questions about this item

Will this 288-pin UDIMM fit the memory slots on my Lenovo Legion C530-19ICB?

Yes, the module is a 288-pin DDR4 UDIMM designed for the C530-19ICB and C730-19ICO desktop chassis.

What is the correct way to seat the module so the system recognises the full 8GB?

Align the notch with the slot key, press down firmly until both side clips click into place, then verify 2666MHz operation in BIOS.

Does the lack of a heat spreader mean I need to add cooling or replace the module sooner?

No, the 1.2V JEDEC-standard module runs within thermal limits without a spreader and is covered by a limited lifetime warranty.
