Ready for ThinkCentre M70a G3 M70q M90q M90s G2

This 8GB DDR4 SODIMM is built for the Lenovo ThinkCentre M70a G3 M70q M90q M90s G2 families. It targets owners of those compact desktops who need a straight swap for the factory module. The JEDEC compliant stick runs at 3200MHz with CL22 latency and 1.2V power.

Fits the factory slot without extra parts

The 260 pin unbuffered non ECC design matches the original socket so no adapter or bracket is required. One rank 1Rx8 organisation keeps the electrical load light for the small form factor board. Installing it restores the memory channel to full width without changing any BIOS setting.

Replaces a long list of Lenovo part numbers

The module covers replacements such as 5M30Z71698 5M30Z71708 5M30Z71710 5M30Z71712 5M30Z71720 5M30Z71751 5M30Z71810 5M31K03078 and many others. Builders who need ECC registered DIMMs or a different pin count cannot use this kit.

商品問答

What sustained-use limit appears first with this DDR4 3200 CL22 module?

The CAS latency of CL22 at 3200 MT/s sets the timing boundary you hit under continuous load

How much heat or power does the 1.2 V 260-pin SODIMM produce when running all day?

It operates at the standard 1.2 V without a heat spreader, so thermal output stays within normal DDR4 SODIMM limits

Which Lenovo ThinkCentre models must I already own for this 8 GB upgrade to work?

It is validated for ThinkCentre M70a G3, M70q, M90q and M90s G2 systems
