With its Core Ultra 200S range of processors, Intel became the first CPU manufacturer to support CUDIMMs (Clocked Unbuffered Dual Inline Memory Modules). Essentially just standard RAM sticks, each one sports a tiny module called a client clock driver (CKD for short) that boosts the signal to ensure it remains stable at very high clock speeds.
The first round of CUDIMMs, such as Corsair's Vengeance DDR5-8400 set, went down the performance route, but there is an alternate use of the CKD. Rather than keeping things nice and clean at high speeds, it can do the same for when a DIMM is loaded to the hilt with memory chips.
