The conventional wisdom on buying a laptop says the average person doesn't need a bucketload of RAM. But if you're not the average person and you're hitting a performance wall with today's 8GB RAM modules, you've been out of luck.
Enter I'M Intelligent Memory, which claims its new 16GB modules will take your Broadwell U-based laptop or Mini NUC-style PC beyond what even Intel will approve.
I know, you don't believe me. I wasn't sure either when I'M Intelligent Memory contacted PCWorld to declare in triumph that it could take a laptop or NUC to 32GB of RAM. That's because Intel's official limit for RAM on its 5th-gen Broadwell CPUs is 16GB. Period. That's where I'M Intelligent Memory claims it worked its magic to get beyond that limit.
JEDEC, the industry body that sets RAM standards, dictates that SO-DIMM RAM modules must contain only 16 chips. That's made achieving high-capacity RAM modules very difficult with the density of memory wafers. Because of this limitation, modules have been stuck at 8GB for years.
I'M Intelligent Memory says to achieve the higher density it's using a unique stacking process, where it takes two 4-Gigabit chips and stacks them to make an 8-Gigabit chip. It then uses these modules to produce its 16GB modules, while others on the market are stuck at 8GB.
The sticky part in all of this is Intel's approval. Intel told PCWorld it would not validate a 32GB configuration for Broadwell, but it would provide white paper guidance. Company officials added that it "should" work technically. In other words, you're doing it at your own risk.
I'M Intelligent Memory officials, however, "guaranteed" it would work.
Not content to take the company at its word, I tested a couple of modules against the company's claims. Because the only laptops I have with Broadwell chips are Ultrabooks with soldered-down RAM, my only real option was to use Intel's new Broadwell-based NUC. The unit I used is the NUC5i5RYK with a Core i5 5250U inside of it.
As you'd expect, installing the modules is no different than for any other RAM except damn, 16GB a piece!
Once I put the modules in place, I also decided to hot-rod the NUC a little more by using Samsung's XP941 M.2 PCIe module in it. The SSD is rated at more than 1GB of read speed.
With the M.2 and RAM in place, I booted up and performed a clean install of Windows 8.1 Enterprise. I wanted to see whether the memory was stable enough to survive an OS install.
During my testing I experienced no issues. In fact, the entire experience was pretty boring. Certainly more boring than my attempts to get that Samsung XP941 to boot in the Dell XPS 13. That ended in utter failure, as Dell's current BIOS doesn't seem to support booting to PCIe devices.
