UEFI BIOS
The ASUS PRIME B760-PLUS D4 has a 128Mb American Megatrends Inc. UEFI flash ROM. It supports WOL, PME, and PXE. Aside from that, ASUS gives no further specifications. However, the implementation is essentially precisely the same as that of other ASUS motherboards and exactly what you would expect. It does lack some of the more extensive options found in the UEFI menus of the more expensive ROG motherboards.
BIOS version 0810 was used for all testing. However, screenshots were taken on version 0402 which is the initial version these boards came with. There is no difference between the versions in terms of options or settings.
ASUS has what is in my opinion, the best UEFI implementation bar none. Not necessarily from a technical perspective but from a design perspective. The interface is probably the most intuitive of all the UEFI menus I’ve used. Unlike ASUS’ competition, ASUS came to this design right out of the gate and only iterates on it occasionally. The other brands have often done radical redesigns over the years as their interfaces weren’t as well received. Some brands practically copy ASUS’ design outright only changing it enough to avoid legal trouble.
Like any other UEFI BIOS these days, ASUS’ boards usually default to an EZ-mode that distills the most commonly used settings and information displays into a single menu. Fan speeds, XMP memory settings, boot order, time and date, and RAID settings can be adjusted here. There are many wizards for walking you through these settings. However, the EZ mode only allows you to do so much as these controls are rudimentary at best. Though the wizards will allow for some flexibility here.
The ASUS PRIME B760-PLUS D4 does not have a sophisticated external clock generator or voltage controller. Even if it did, the VRMs are relatively basic. Meaning, while all the usual overclocking settings are present the granularity found on more expensive motherboards is lacking. You will not be able to finely adjust the voltages or clock speeds in the same smaller increments as you would on a higher-end motherboard. Given the state of overclocking these days, this is only going to affect a small subset of users that probably aren’t looking toward this level of the board in the first place. Even so, if you are on an extreme budget, you do have some overclocking capability here but it is limited.
You do get what you pay for with these types of things. That being said, the motherboard is still fully capable of memory overclocking. While it’s unlikely to break any records, it’s more than capable of pushing DDR4 RAM into the DDR4 4000MHz+ ranges with the right modules. Voltage adjustments for that are about as granular as they would need to be. You also have the usual myriad of timing settings that go well beyond what most people have the patience to configure.
Given the state of overclocking, what you would most likely do for extra performance is disable the Intel PLL limits. By default, you are limited to something like 241w and this motherboard defaults to that whereas Z790 boards default to an unlimited PLL. Though rarely does this make a huge amount of difference as we’ve done the testing and the results are usually similar, though they do on aggregate improve with an unlimited PLL provided you have sufficient cooling to handle the extra wattage. It does result in a temperature that’s a few degrees of the increased CPU temperature.
Despite its budget-oriented design, the fan control is the same as it is for any other ASUS board which is to say it’s quite excellent. It offers fine control over the fans by allowing any fan header to be manually configured or operated by various profiles. The BIOS also has the usual EZ Flash utility, Secure Erase tool, user profile system, and Armory Crate controls. The UEFI BIOS tools are one of the features that set ASUS apart from other brands.
