The Digital Linear Voltage Regulator (DLVR) is a power supply device developed by Intel that was intended for use in 13th generation CPUs. The idea is to improve efficiency and would be used in Intel’s Raptor Lake CPUs. An ASUS employee confirmed that Intel DLVR will not be included in Raptor Lake, but may be included in future generations.
By matching the voltages to the motherboard’s power, Intel DLVR improves power efficiency. “Digital Linear Regulator Clamping Method and Apparatus” is the name of a patent originally found on Reddit. The Intel DLVR should function in conjunction with the motherboard’s main voltage regulator. The procedure had to be simplified while allowing for cost-effective power level control and improved heat dissipation. The result would be a 20% gain in improved efficiency and management.
The Intel DLVR patent demonstrated a voltage drop of 160 mV and as much as 25% reduction compared to normal approximations. Intel’s 13th Gen Raptor Lake CPUs were supposed to be the first to use the new DLVR architecture, but they were switched to bypass mode midway through development. ASUS has included this option on their latest ROG Z790/Z690 motherboards simply because they believe future CPUs will still support DLVR. The BIOS feature is called “CPU DLVR Bypass Mode Enable”, but it doesn’t seem to trigger any significant system improvements.
While the support was available, no desktop CPU can now take advantage of it, according to “Shamino,” an ASUS employee and the company’s overclocking expert. Two other board makers also confirmed that DLVR was on its way to the desktop market before being discontinued early in the Raptor Lake CPU development process. Before the technology moved to the desktop market, it was mostly usable only for mobile processors; so we can see it introduced first.
The specific architecture that will enable DLVR in the future is uncertain. Intel has yet to confirm whether it will be located at Meteor Lake. The 14th Gen Meteor Lake CPUs use the latest LGA 1851 socket, which will also be compatible with the 15th Gen Arrow Lake CPU range.
If the previously expected Raptor Lake Refresh occurs, the inaccessible procedure may occur sooner. It’s uncertain and we’ll have to wait for more material to be released to learn more about the future of Intel DLVR.
