Mac Pro Cylinder memory upgrade

This 8GB DDR3 1866MHz ECC RDIMM module is built for the Apple Mac Pro Late 2013 (MacPro6,1). It runs at PC3-14900 speed with a registered design and 2Rx4 organisation. The part matches Apple order numbers ME253LL/A, MD878LL/A and MQGG2LL/A.

Replaces slower or smaller DDR3 modules

The jump is worth it when your cylinder Mac Pro shows memory pressure during multitasking or when you need ECC registered stability for workloads that demand error correction. Each module operates at 1.50V and uses major-brand chips tested to strict standards.

Suits owners of MacPro6,1 seeking ECC RDIMM capacity

Builders who need non-ECC UDIMM memory or a different pin count should look elsewhere. The module is validated for Xeon E5-1620v2, E5-1650v2, E5-1680v2 and E5-2697v2 processors installed in the 2013 cylinder chassis.

Questions sur cet article

Will this 240-pin RDIMM fit the Mac Pro Late 2013 memory slots?

Yes, the 240-pin RDIMM form factor is the exact module type used in the Mac Pro Cylinder (MacPro6,1).

What is the correct way to install this ECC registered module in the Mac Pro?

Power off the Mac, open the side panel, release the memory tray, and press the module straight down until the ejectors click. The step people miss is seating the module fully before locking the tray back.

Does this 1.50V DDR3 module need any firmware update or periodic replacement?

No firmware update is required; the module is tested for the supported Xeon CPUs. ECC registered DIMMs have no scheduled replacement — they stay in service until a memory error appears or capacity needs change.
