We're only a few weeks away from the official reveal of Alder Lake, so it should come as no surprise that more leaks have surfaced online. The latest case appears to show that Intel's 12th generation processors have a powerful memory controller that allows enthusiasts to push DDR5 memory above DDR4 already.
We recently saw an Alder Lake leak, but it was mostly related to the good performance of the Intel Core i9-12900K CPU versus the AMD Ryzen 9 5950X, which shows the current performance. King. The Core i9-12900K appears to be, at least in its early stages, the best desktop part from Team Blue Labs, but there are still plenty of unknowns to make a clear judgment about its capabilities. There is a lot of speculation about DDR5 and how it will affect the performance of Alder Lake in certain scenarios such as gaming. The new CPUs support DDR4 and DDR5, and most of the leaks we've seen so far from the Core i9-12900K have to do with DDR5 memory.
If there's a new leak from a Twitter user, the reputable REHWK CPUs and Alder Lake's powerful memory controller will be a boon for those who want more RAM. In the CPU-Z screenshot shared by Revealer, we also get more confirmation on the general specs of the Core i9-12900K, which is a 16-core, 24W 125W TDP without AVX-512 support. .

The D GIGABYTE appears to be paired with the Tach690 board. By default, DDR5-6200 runs according to JEDEC specifications at DDR5-4800 and 42-39-39-77-116 timings at 1.1V. In the XMP-6200 specification, the timing is set a little more to 38-38-38-76-125, but the operating voltage is reduced to 1.5 V for stable operation. Other than that, there is another specification for the XMP-6400 with easier timing and an operating voltage of 1.45V.
Honestly, an interesting feature introduced with Rocket Lake is Gear Modes, in which Intel responds to AMD's Infinity Fabric modes to overclock memory. Gear 1 lets you run the same memory controller and memory at the same frequency, while Gear 2 and Gear 4 let you run them on different frequencies. In the case of the Gear 2, the memory controller operates at half the memory frequency, and the second mode allows the memory controller to operate at a quarter of the memory frequency.
