    Although Intel Corp.’s latest “Skylake” microprocessors officially support only DDR4 and DDR3L memory technologies, Asustek Computer claims that its Intel Z170-based motherboards with 240-pin DIMM slots will work with standard DDR3 memory modules with industry-standard voltages.

    DDR4 SDRAM memory has default voltage of 1.2V, but memory modules for overclockers with increased clock-rates feature 1.35V – 1.4V voltage. By contrast, standard DDR3 modules have 1.5V voltage, while DDR3 for overclockers sports 1.65V voltage. DDR3L standard specifies low voltage of 1.35V, which means that it should work with DDR3/DDR4 controllers without overvoltage of the latter. However, it looks like Intel’s “Skylake” chips can work with high-end DDR3 modules too.

    In a conversation with web-site, an Asustek representative said that the company’s Asus Z170-P D3, Z170M-E D3 that support DDR3 memory modules are fully-compatible with 1.5V and 1.65V DDR3 DIMMs. Previously it was believed that Intel’s “Skylake” processors only support DDR3L with 1.35V voltage, whereas support of industry-standard DDR3 is beyond specifications of the processor.

    According to Asustek, the two DDR3-supporting LGA1151 mainboards were launched because of the price disparity between DDR3 and DDR4 in a bid to address customers in budget, who do not want to buy new memory modules or pay extra for DDR4. However, such motherboards are not really popular.

    What about the other brands?
