Insider REHWK, who previously shared the results of testing the Core i9-12900K in the synthetic test Cinebench R23, published new data related to the expected Alder Lake platform. This time, he provided screenshots of the CPU-Z program, which demonstrate the overclocking capabilities of DDR5 RAM.
In the images provided, it can be seen that the tests used DDR5-6200 memory from Gigabyte (presumably the Aorus brand). At the same time, the enthusiast overclocked the RAM frequency to 4004 MHz, that is, up to a data transfer rate of 8008 MT / s with timings CL50-50-50-125-150-2T. In other words, the effective memory mode was DDR5-8000. To achieve this speed, it was necessary to raise the memory voltage to 1.5 V.
The image also shows the DDR4-6200 overclocking profile supported by the modules with more efficient CL38-38-38-76-125-2T timings. The memory was tested as part of the Gigabyte Z690 Tachyon motherboard, designed specifically for manual overclocking enthusiasts. According to VideoCardz, this board has only two memory slots.
12th Gen Intel Core processors will officially support DDR4-3200 and DDR5-4800 RAM by default. With reference to their sources VideoCardz reports that DDR5 memory modules are already shipping to retailers. The start of their sales is expected simultaneously with the launch of the Alder Lake processors, that is, on November 4.
