8GB DDR4 2400 SODIMM for ThinkPad

This 8GB DDR4 2400MHz SODIMM module is built to upgrade Lenovo ThinkPad E485, T580 and 13 2nd Gen laptops. It runs at 1.2V with CL17 timing and uses a 260-pin unbuffered non-ECC design. The single stick installs directly into an available slot. Computer Memory Solutions guarantees compatibility with the listed models.

Suits owners of the named ThinkPads needing more

Buyers with other laptop models or desktops should look elsewhere because this module is validated only for the three ThinkPad systems listed. It does not support ECC or registered configurations. The kit contains one stick, so systems requiring matched pairs will need a second identical module purchased separately.

260-pin DDR4 2400 SO-DIMM form factor decides fit

The 260-pin SO-DIMM keying and DDR4 2400 signalling determine whether the module seats and runs in your machine. Only the ThinkPad E485, T580 and 13 2nd Gen are confirmed compatible by the manufacturer. Verify your exact model before ordering.

Questions about this item

How do I install the 260-pin DDR4 SODIMM in my ThinkPad T580, and which step is often missed?

Power off, unplug, remove the base cover, insert the module at an angle until the gold contacts disappear, then press down until both side clips click; the step most people miss is pressing firmly enough to engage both clips.

What maintenance or replacement will the CM1024642400SO need later?

No scheduled maintenance is required; if a fault appears it is covered by the limited lifetime warranty from Computer Memory Solutions.

What limit appears first when the 2400 MHz CL17 memory runs under sustained load?

The CAS latency of 17 cycles at 1.2 V sets the timing boundary before thermal throttling becomes a factor.
