It indicates the CPU isn't confirmed to handle more than 128GB of total stick capacity, and if it fails to do so it won't start up. There remains a possibility it might function.
The motherboard can accommodate a chip with 256GB storage. Various types of chips can fit into the same socket.
To achieve 256 GB on the motherboard, you need large memory modules, typically 64 GB if you have four slots. These modules rely on numerous small memory chips to reach that size, since the largest available RAM chips are around 16 gigabits (2 GB). To construct a 64 GB module, they would require 32 such tiny chips. Because of DDR4 chip design, they’re organized in sets of eight, which means memory controllers usually handle one set of eight and another of eight. This setup lets manufacturers create modules with capacities like 512 MB, 1 GB, or 2 GB chips, along with multiples of eight to form the sticks. Some processors can’t manage more than two sets of eight, so the CPU’s memory controller isn’t built for that. These high-capacity sticks also demand more power from the CPU, increasing its load and potentially causing higher energy use. Inside the chip, this extra demand can push it to consume around 0.25 watts per chip, totaling 2-3 watts per stick. Consequently, even if some CPUs support it, they might cap themselves at two sticks or require you to lower your RAM speed significantly to avoid errors. The motherboard itself faces challenges too, needing sufficient power to supply all the chips—each tiny chip uses about 0.25 watts, so eight to sixteen chips could draw 2-3 watts per stick, while using thirty-two chips might push it up to 5 watts per stick. A budget board might manage 15-20 watts overall, but premium boards can handle 50-100 watts or more.
I'm assembling a workstation tower and explored the 2066 socket options. I found the 10900kf Intel chip, which supports dual-channel memory and has 128GB RAM. I plan to install 256GB, aiming to avoid unnecessary costs or components. I want to confirm if this processor can effectively use the 256GB with 2399MHz RAM without wasting resources.
