X299 VRM thermals have been a topic of interest in the lab lately, as we’ve continued to learn how to work with our new power testing tools and have fully revamped CPU thermal testing. The time will come eventually, but for now, we’ve worked with Buildzoid to run some calculations on VRM thermals with the Gigabyte X299 Gaming 9 motherboard. These numbers are based off of GN testing for this video, where we overclocked the CPU to 4.5~4.6GHz and checked for power consumption at the 8-pin headers (of which there are two).
The Gigabyte X299 Gaming 9 motherboard makes some interesting choices with its VRM components, ultimately balancing between “ridiculous overkill,” to quote Buildzoid, and merely adequacy. The board is one of the higher quality motherboards out there right now, and so is worth a watch on the PCB break-down:
Following our AMD Radeon Vega: Frontier Edition review and preceding tear-down, Buildzoid has now returned to analyze the AMD Vega: Frontier Edition PCB & VRM. This is a 12-phase design (doubled-up 6) that ultimately resembles something similar to a 290X Lightning, making it the hands-down best VRM we've seen on a reference card. Given that Vega: FE is $1000, that sort of makes sense -- but Buildzoid does pose some questions as to what's necessary and how much current is really going through the card.
When interviewing EVGA Extreme OC Engineer “Kingpin,” the term “dailies” came up – as in daily users, or “just gamers,” or generally people who don’t use LN2 to overclock their GPU. The GTX 1080 Ti Kingpin card is not a device built for “dailies,” but rather for extreme overclockers – people who are trying to break world records.
Cards like this – the Lightning would be included – do have a reason to exist. Criticism online sometimes calls such devices “pointless” for delivering the same overall out-of-box experience as nearly any other 1080 Ti, but those criticizing aren’t looking at it from the right perspective. A Kingpin, Lightning, or other XOC card is purchased to eliminate the need to perform hard mods to get a card up to speed. It’s usable out of the box as an XOC tool.
