Intel’s newCore 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/swhile Kingston reckons it has donea 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.
But let’s pretend, just for a moment, that you could hit DDR5-12000 at full CPU clocks and without exotic cooling. How much difference would that actually make?
As it happens, Nick recently took a look atArrow Lake gaming performance using various memory speeds. He found that the jump from the official DDR5-6400 to DDR-8200 netted an increase from 103fps to 109fps in Cyberpunk 2077 at 1080p, so just over 5%.

Baldur’s Gate 3 shows even better results, with a 10% gain in average frame rates at 1080p going from DDR5-6400 to DDR-8200. However, Homeworld 3 and Total War: Warhammer III showed more modest gains, adding just one FPS and two FPS respectively.
What you make of those kinds of gains is subjective. On the one hand, you’re going to struggle to feel the benefit in the real world. On the other, 10% is a pretty hefty jump when you consider how modest the gaming performance gains have been from the latest CPUs from bothAMD with Zen 5andIntel’s Arrow Lake.

Best RAM for gaming: the latest and greatest
AMD’s newRyzen9000 chips are only slightly faster when it comes to gaming than theirRyzen 7000 predecessors, while Intel’s new Core Ultra 200S CPUs are actually a bit slower for games than theiroutgoing 14th Gen Raptor Lakeequivalents. So, any additional performance gains from fast memory are welcome.
That said, one can’t just assume that adding yet more memory frequency will result in proportionally higher frame rates. But you would expect at least a little more performance. So, DDR-12000 would likely help Arrow Lake look a little less disappointing in the gaming stakes.
Of course, it’s a thoroughly academic consideration given that there’s no practical way to actually game with memory running at 12,000MT/s. But it’s a big old number and it helps keeps things moving in the right direction. It’s just worth being realistic about the likely rewards before you spend hard on some fancy DDR5.
