Benchmarks and CPU-Z screenshots of an Intel Core i9-12900K running with overclocked DDR5 memory have been shared on Twitter by user REHWK.

A new screenshot from the CPU-Z software is displaying Gigabyte's own DDR5-6200 memory kit, overclocked to a speed of 8000 MT/s.

The system was built on a Gigabyte Z690 Tachyon motherboard, which is designed specifically for overclockers and enthusiasts like myself. It appears that Gigabyte will develop its own high-speed memory with an XMP-6200 profile and timings of 38-38-38-76-125 bits per clock cycle. To attain this speed, 1.5 V will be required, which is 400 mV greater than the voltage required by regular DDR4-4800 memory. You can see that the RAM has been overclocked to 4004 MHz, which is equivalent to 8008 MT/s. CL, tRDC, tRP, tRAS, and tRC have timings of 50-50-50-125-150. By default, the 12th Generation Core series will handle either DDR4-3200 or DDR5-4800 memory speeds.
