The power is back on. The power company rep said, "A tree fell on the line." That was really convenient because they were able to run a new service to a home under construction nearby.
Sizzling is never good...unless it's bacon cooking.I have requested a trade-in for my OCZ ZX 1000W power supply from PC Power & Cooling. I am now running just two video cards of 5 on the mining rig. My order for a used 1000W power supply (to run the 5th video card) has been delayed by the weather. I plan to get the Turbo Master 1350W power supply. With the trade-in, it will cost $225. If I am lucky, the trade-in unit could be under warranty.
One of the beta testers, who is more knowledgeable about computers than me (has more test equipment), showed graphs of the WCG Beta work units causing voltage spikes and said the spiking loads could lead to power supply failures. I think my unit has been going bad for several weeks. When it made sizzling noises, the computer would lockup.
Luckily for some people, Nvidia's "older" RTX 30 series GPUs like the RTX 3090, 3080, 3070, and 3060 Ti will not receive the mining limiter. However, this might change soon, depending on Nvidia's plans.

The simple hack reportedly requires a clean driver install with Nvidia's latest GeForce 470.05 Beta driver — some report the need to flash the GeForce RTX 3060 graphics card with a hacked vBIOS, though in our testing that's not required. Nvidia apparently messed up something in this particular driver that renders its anti-mining algorithm completely useless.
