Hibernation.

Win7, Win10.

It's quite common for mining rigs to have "small" SSD, just enough for the OS and Claymore, so probably doable on a 64GB SSD even.

However, with swap file, page file, and setting VM to 16GB or more, (16GB is the minimum), it's easy to see some big chunks of disc space be consumed.

Worse still, if you have 16GB of RAM, with a default Win install, you're going to see some 12~16GB stolen by hibernation.

Considering one probably does not want a mining rig going to sleep or hibernating, tip of today would be to disable those, and then review your power settings, as those too can be hijacked by various apps etc,.

Open an admin command prompt

powercfg /h off


That's it, eliminates a potential cause of mining halt, and recovers a nice chunk of RAM you can then give to Claymore as VM if you need to.

Happy Mining
