System-Specific SODIMM

This 4GB DDR3 SO-DIMM is built for the Lenovo Essential B570 notebook series. It uses a 204-pin interface and operates at 1.5V with CL7 timing. The unbuffered, non-ECC module suits owners who need a direct replacement or a single-slot capacity increase.

Upgrade considerations

The laptop accepts two modules with a 16GB ceiling, so this stick leaves the second slot free for future expansion. No heat spreader is fitted, keeping the profile low for tight chassis clearance. Compatibility is guaranteed for the listed series by the manufacturer.

Sustained operation

Major-brand DRAM chips and a limited lifetime warranty from the maker indicate stable performance during extended sessions. The CL7 7-7-7 timings at 1333MHz provide consistent latency without voltage increases. Buyers who want more storage or a dual-channel kit should look elsewhere.

Questions about this item

What is the maximum total memory the Lenovo B570 can accept with this 4GB module installed?

The Lenovo Essential B570 supports a maximum of 16GB across its two SODIMM sockets, so this 4GB stick leaves room for another module up to 12GB.

How much power does this DDR3 SODIMM draw at its rated 1.5V during continuous operation?

The module runs at the standard DDR3 voltage of 1.5V; actual power draw depends on workload and the notebook's memory controller, not on the stick alone.

Does the Lenovo B570 need a BIOS update or specific chipset revision before this CL7 1333MHz stick will be recognised?

Computer Memory Solutions guarantees compatibility with the Lenovo Essential B570 series as listed; no extra hardware is required beyond an available 204-pin SODIMM slot.
