Intel's 9th-gen CPUs will support 128GB of DDR4 RAM

Intel unveiled the flagship Core i9-9900K, i7-9700K, and i5-9600K, along with its new Z390 chipset, last week. Now, the company has confirmed to Anandtech that one of the benefits of these CPUs is their ability to support 128GB of RAM. An update will arrive “in a few months’ time” that will enable the increase in system memory capacity.

Adding 128GB of RAM to a consumer system with four memory slots is made possible through support for double height double capacity 32GB DDR4 modules, as well as the new 16Gb DDR4 chips from Samsung.

“The new 9th Gen Intel Core processors memory controller is capable of supporting DDR4 16Gb die density DIMMs which will allow the processors to support a total system memory capacity of up to 128GB when populating both motherboard memory channels with 2 DIMMs per Channel (2DPC) using these DIMMs. As DDR4 16Gb die density DIMMs have only recently become available, we are now validating them, targeting an update in a few months’ time,” said Intel, in a statement.

Considering that you can spend over $550 on 64GB of DDR4-2666 RAM right now, expect 4x32GB kit prices to be pretty eye-watering—probably over the $1200 mark. For most people, 128GB is massive overkill, but it will likely be welcomed by professionals who don’t want to go down the full workstation route, and those looking for bragging rights.

Ultimately, users of small form-factor PCs may benefit most from the double height memory modules, as they will allow 64GB (2x32GB) to be packed into small volume systems. We saw the first signs of this back in May, when Samsung announced it had started mass production of the world’s first 32GB DDR4 SoDIMMs designed for gaming laptops.

Interesting that Intel is only in the process of validating now... Since Samsung has had it available since March (if they began mass-production then, they certainly could have shipped a few over to Intel had they been asked), it makes you think this was a late decision by Intel... perhaps to offset the inevitable benchmarks that will show that AMD is a far better value.

Intel marketing: "But we're going to have 128GB of RAM in our systems!"

Consumer: "Great! When?"

Intel Marketing: "Not until AMD releases another CPU that also has it.... you weren't supposed to ask questions!!!!"

PC companies will still limit their mid-range desktops and laptops to a certain amount. Maybe 32GB max. Otherwise, people will have the incentive to keep their computers longer and not buy new.

Tell me about it! Is there any non server system that supports 128 GB for 9700 & 9900Ks? I guess NOT.
