DDR5 memory modules and supporting platforms are not yet on the market, but DRAM manufacturers have begun an informal DDR5 overclocking race. Recently, ADATA’s XPG Overclocking Lab (XOCL) announced that it has successfully overclocked the company’s DDR5 memory modules to 8,118 MT/s. This is the first time that a memory module factory has demonstrated an overclocked DDR5 SDRAM stick.
In order to achieve record data transfer rates, Adata’s XPG Overclocking Lab (XOCL) uses pre-production 16GB DDR5 memory modules based on SK Hynix ICs, with an inventory data transfer rate of 4,800 MT/s and unknown Intel Z690-based The motherboard is equipped with an undisclosed Intel 12th-generation Core “Alder Lake” processor. The module can reach 8104 MT/s and 8188 MT/s in single channel mode, and the system remains stable enough to load Windows and CPU-Z software.
Adata did not disclose the cooling method it uses for the CPU and the voltage it sets for the DDR5 module to reach 8188 MT/s. All the content displayed by the company is CPU-Z screenshots.
Speaking of modules, it is important to note that we are indeed dealing with pre-production unbuffered DIMMs labeled AX5U5200C38 16G-BLA, so as the name suggests, this module should run under DDR5-5200 with CL38 CAS latency. At the same time, its SPD has a 1.35V XMP-6800 CL46 entrance, which may be ready to launch by Adata in the foreseeable future. In any case, the default data rate of most DDR5 modules to be released this year will be 4800 MT/s according to the JEDEC standard.
So far, leading memory chip manufacturers such as Micron, Samsung and SK Hynix have proven that their DDR5 memory chips can work at speeds of 7200 MT/s or even 8400 MT/s. These experiments were conducted using DRAM chips or device test equipment with stand-alone DDR5 DRAM controllers. Although these experiments revealed the potential of DRAM, they did not use real-world workloads to test memory ICs under real-world conditions.Memory module factory followed closely behind: Netac said it is developing DDR5-10000 The module is as early as April, and Adata says it has run successfully DDR5 speed is 12600 MT/s In the laboratory in August.
This time, Adata uses real (albeit pre-production) hardware to achieve very high data rates, and can even start Windows with the CPU-Z software. Of course, it will take some time for the company and its peers to release the actual DDR5-8200 memory module, but at least we know that even the current generation of modules can work at extremely fast speeds.
