BFL Monarchs: Getting Hands-On and Inside Talk

Nah, this one’s legit from a guy I talked to. I’ll run it for a bit before taking it apart. Wondering about the thermal paste I’ll need.

Gotta get baselines first. Need to track temps on the chips and FET drivers, plus check the clock rates with a scope. Thursday’s the day!

It’s here! 700gh sticker looks sweet, solid build. I can’t power it up just yet since I have to head out, but I’ll fire it up later.

Got it running! Using bfgminer 4.5.0, and it’s hashing fine. Both plugs and a Corsair 500 PSU are powering it up. The board's back is at 119f, temps around 105 overall. Hash speed is at 660gh, not bad at all. It’s making this high-pitched squeak from the power supply wonder if it’s the chokes.

Now for the fun part: here’s the output from chiliflash.
