The MacBook Pro 2015 Retina (15-inch) features Intel Core i7-4770HQ or i7-4870HQ, 15.4″ Retina (2880×1800) display, and soldered DDR3L-1600MHz memory (16GB maximum). While RAM cannot be upgraded after purchase, the SSD is user-replaceable, making it the primary upgrade path. This guide covers complete MacBook Pro 2015 Retina (15-inch) compatibility for upgrades.
RAM Compatibility for MacBook Pro 2015 Retina (15-inch)
The MacBook Pro 2015 Retina (15-inch) uses soldered DDR3L-1600MHz memory that cannot be upgraded after purchase. You must choose your RAM configuration at the time of ordering.
Memory Type: DDR3L-1600MHz (soldered to motherboard)
Stock Configuration: 16GB
Maximum Capacity: 16GB
Upgradeable: No — RAM is permanently soldered
| Configuration | Memory | Total | Best For |
|---|---|---|---|
| Base config | 16GB DDR3L-1600MHz | 16GB | Productivity, moderate multitasking |
Since RAM is soldered, choosing the right amount at purchase is critical. For general productivity and web browsing, 16GB is adequate. For professional use, video editing, or running virtual machines, configure with the maximum available. There is no way to upgrade later, so err on the side of more RAM if your budget allows.

Maximum Capacity: 2TB (aftermarket adapter + NVMe)
Interface: M.2 2280, NVMe over PCIe Gen 3

| Recommended upgrade | 1TB replacement | 1TB | Most users, good balance of space and cost |
| Premium upgrade | 2TB replacement | 2TB | Large file collections, creative professionals |
For the best performance, the Samsung 990 Pro and WD Black SN850X are top picks for PCIe Gen 4 drives. To upgrade: power down, remove bottom panel, locate the M.2 slot, remove the retaining screw, slide out the old drive, insert the new one at 30 degrees, and secure with the screw.
