 ### About XMRigCC
 
 XMRigCC is a fork of [XMRig](https://github.com/xmrig/xmrig) which adds the ability to remote control your XMRig instances via a Webfrontend and REST api.
-This fork is based on XMRig (2.4.2) and adds a "Command and Control" (C&C) server, a daemon to reload XMRig on config changes and modifications in XMRig to send the current status to the C&C Server.

 The modified version can also handle commands like "update config", "start/stop mining" or "restart/shutdown" which can be send from the C&C-Server. 
 
 Full Windows/Linux compatible, and you can mix Linux and Windows miner on one XMRigCCServer.

+## Doublehash thread Mask (only for low power mode (av=2 and av=4))
+With this option you can limit doublehash to the given threads (mask). This can significantly improve your hashrate by using unused l3 cache. The default is to run av2/av4 mode on all threads.

Tasks heavily using a processor cache, such as video playback, can greatly degrade hashrate. Optimal number of threads depends on the size of the L3 cache of a processor, 1 thread requires 2 MB of cache.
