Theoretically bananas bandwidth, but not terribly practical for gaming.
Intel’s new Core Ultra 200S chips, otherwise known as Arrow Lake, officially support DDR5-6400 RAM. But the memory specialists at G.SKILL and Kingston have been overclocking the twangers off some fancy new DDR5 DIMMs. The result? Speeds not far off twice as fast as both memory vendors have blasted through the DDR5-12000 barrier.
We’ll come back to how relevant any of this is in a moment. But for the record, G.SKILL is claiming 12,066MT/s while Kingston reckons it has done a tiny bit better at 12,108MT/s.
In part these figures are possible thanks to the use of the latest CU-DIMM memory tech. CU-DIMM memory sticks sport a dedicated clock driver. The idea is to reduce the CPU’s role in memory clock synchronization and in turn improve stability and enable higher memory frequencies.
Inevitably, there are numerous caveats to all this. For instance, Kingston’s result was not only achieved courtesy of liquid nitrogen cooling for the DDR5 sticks. It also entailed running the Core Ultra 7 265KF CPU with its E cores disabled and the P cores running at just 400MHz.
