Dell Precision T7600/T7610 upgrade

This OWC 8GB DDR3L 1600 CL11 ECC Registered RDIMM is built for Dell Precision T7600 and T7610 workstations. It delivers 8GB of PC3L-12800 memory at 1.35V with a 1Rx4 rank configuration. The module uses 240-pin DDR3L technology and includes error-correcting code for data integrity. It is designed for registered memory slots only and will not work in standard desktop computers.

Replaces Dell A7134886 A7545680 RKR5J

This module replaces Dell part numbers A7134886, A7545680, RKR5J and SNPRKR5JC/8G with a direct-fit upgrade. The jump is worth it when your workstation needs more capacity for virtualisation, large datasets or extended uptime. ECC registered memory cannot be mixed with unbuffered modules, so all slots must use the same registered type. Buyers who need non-ECC or unbuffered memory for consumer platforms should look elsewhere.

Registered ECC slot requirement

Installation requires available 240-pin DDR3L registered DIMM slots on a compatible Dell Precision motherboard. The 1.35V DDR3L voltage matches the platform specification and frees headroom compared to higher-voltage DDR3 modules. No heat spreader is fitted, so airflow in the memory bay must be adequate. Systems that only accept unbuffered memory or a different DDR generation cannot use this module.

Questions about this item

Will this 240-pin DDR3L RDIMM fit the memory slots in a Dell Precision T7600 or T7610?

Yes. The module is a 240-pin DDR3L ECC registered DIMM built to the 1.35 V JEDEC standard and is listed as compatible with both the T7600 and T7610 workstations.

What is the correct way to install this registered ECC module, and what common mistake should I avoid?

Power down the workstation, open the chassis, align the notch on the 240-pin edge connector with the slot key, and press firmly until the retention clips lock. Do not mix this registered DIMM with any unbuffered memory; the system will not boot if the two types are combined.

When will this DDR3L 1600 module need to be replaced or serviced?

The memory itself has no moving parts and requires no scheduled maintenance. Replace it only if a diagnostic tool reports correctable or uncorrectable ECC errors, or if you upgrade the workstation to a platform that no longer supports DDR3L registered DIMMs.
