Patriot Signature Line 32GB DDR4-3200 CL22 SO-DIMM Laptop Memory, 260-pin, 1.2V, Non-ECC Unbuffered

The Patriot Signature Line 32GB is a DDR4-3200 CL22 DDR4 SO-DIMM memory module for everyday laptops and notebooks that need a high-capacity standard module. It is a single 32GB module, so you can add it to a free slot or replace a smaller factory module.

Signature Line is Patriot's standard-spec line: DDR4-3200 with 22-22-22-52 timings at 1.2V, non-ECC and unbuffered, with nothing to enable. At DDR4-3200 each module moves up to 25.6 GB/s, and pairing it with a matching module doubles that in dual-channel.

Before you buy, three things decide whether a memory upgrade works: the memory generation (this is DDR4 — not DDR3 or DDR5), the form factor (SO-DIMM, the short 260-pin laptop module) and how much your system accepts per slot and in total. Speed and latency come after that: a faster module never hurts, because it steps down to whatever the platform runs, but it only helps if the system can use it. If you are replacing a module rather than adding one, note the capacity and speed of what is fitted now — Windows Task Manager (Performance, then Memory) shows the speed in use, the number of slots and how many are occupied.

• 1 × 32GB DDR4 SO-DIMM module
• Manufacturer packaging
• No tools, cables or software — none are needed; most laptops only require a small screwdriver to open the memory cover

• For dual-channel bandwidth, pair it with a second module of the same capacity and speed; on its own it runs in single-channel mode.
• The module runs at the lower of its rated speed and the speed your platform supports — on a DDR4-2400 or 2666 laptop it will simply run at 2400 or 2666.
• 32GB comfortably covers heavy multitasking, large spreadsheets, virtual machines and photo or video editing on a laptop.
• Mixing it with a different existing module usually works, but the system will fall back to the slowest speed and loosest timings of the two — a matched set avoids surprises.
• Fitting it is a five-minute job on most laptops with a memory cover; we can also install it for you at our Limassol store.
• Handle the module by its edges and touch a metal surface first; insert it at about 30 degrees, fully into the slot, then press down until the side clips lock.
• The operating system detects the new memory automatically — there are no drivers to install. The first start after a memory change can take a little longer while the system trains the memory.
• If the laptop has soldered memory plus one free slot, the module adds to the soldered memory; dual-channel then works best when the two capacities match.

• Desktop PCs with full-size DIMM slots — this is a 260-pin SO-DIMM and does not fit a desktop slot.
• DDR3, DDR3L or DDR5 laptops — the notch position is different and the module will not seat.
• Laptops, tablets and ultrabooks with fully soldered memory, including Apple silicon Macs.
• Servers and workstations that require ECC or registered (RDIMM) memory.
