"Elevated operating voltage" my foot.

We've already seen examples of this happening on non-OC'd server-style motherboards that perfectly adhere to the intel spec. This isn't like ASUS going 'hur dur 20% more voltage' and frying chips. If that's all it was it would be obvious.

Lowering voltage may help mitigate the problem, but it sure as shit isn't the cause.

It's worth noting that W680 boards are not a server board, they're a workstation board, and often times they're overclockable (or even overclocked by default). Wendell actually showed the other day that the ASUS W680 board was feeding 253W into a 35W (106W boost) 13700T CPU by default[1].

Supermicro and ASRock Rack do sell W680 as a server (because it took Intel a really long time to release C266), but while they're strictly to the spec, some boards are really not meant for K CPUs. For example, the Supermicro MBI-311A-1T2N is only certified for a non-TVB E/T CPUs, and trying to run the K CPU on these can result in the board plumbing 1.55V into the CPU during the single core load (where 1.4V would already be on the higher side)[2].

In this particular case, the "non-OC'd server-style motherboard" doesn't really mean anything (even more so in the context of this announcement).

They also admit a microcode algorithm produces incorrect requests for voltages, it doesn't sound like they're trying to shift the blame; ASUS doesn't write that microcode

Specifically I think the concerns are around idle voltage and overshoot at this point, which is indeed something configured by OEMs.

edit: BZ just put out a video talking about running Minecraft servers destroying CPUs reliably, topping out at 83C, normally in the 50s, running 3600 speeds. Which is a clear issue with low-thread loads.
