8GB DDR5 SODIMM for Precision 7670 7770

This 8GB DDR5 4800 CL40 module upgrades Dell Precision 7670 and 7770 workstations. It uses a 262-pin SODIMM form factor with 1Rx16 organisation and runs at 1.1V. The non-ECC unbuffered design suits professionals who need a straightforward capacity increase for multitasking and larger datasets.

JEDEC-standard 1.1V operation

The module follows JEDEC DDR5 specifications at 1.1V with CL40 latency. Low voltage keeps thermals modest inside the Precision chassis and draws minimal power during typical workloads. No heat spreader is fitted, so airflow from the system fans handles cooling silently.

Single-slot 262-pin upgrade

One SODIMM slot accepts this 8GB stick, leaving additional slots free for further expansion. Installation is a standard DIY step without tools. The part replaces Dell AB949333 and SNPMVK8PC/8G, so it fits the qualified platform without firmware changes.

Questions about this item

How do I install the 262-pin DDR5 SODIMM in a Precision 7670, and what step do people often miss?

Power off, unplug and remove the battery. Insert the module at an angle until the gold contacts disappear, then press down until both retention clips click. People often stop at the first click and leave one side loose.

What maintenance or replacement will the 8GB 1Rx16 DDR5 module need later?

No scheduled maintenance is required. The module has no heat spreader and runs at 1.1V, so it relies on system airflow. Replace it only if memory diagnostics report errors or you need more than 8GB capacity.

What limit appears first when the CL40 DDR5 4800 module runs under sustained load?

The CL40 latency at 4800 MT/s sets the throughput ceiling. In long workloads the memory controller will hit that bandwidth limit before thermal throttling occurs on this unbuffered 1.1V SODIMM.
