    I'd like to use tripple channel memory with both dual CPUs, can I use 3x16GB sticks or 6x8GB sticks is better?

    Thank you.

    6x8GB for sure. Ram is cheap nowadays, so check for a deal on a 6x16GB setup.

    You're welcome. By the way - thanks for the time and effort you've put into macs fan control app! While the mac version is superb, the windows version - stable/beta, has a weird issue which causes the fans' rpm to drop to 0, causing the SMC sensors to report a glitch with the fans on the next boot into macos. The glitch can only be reset by disconnecting the power cable.

    Didn't know about this and would be happy if you could help me to reproduce the problem! Preferably as a github issue.
    I've just bought a cMP 5,1 today (on ebay) specially for an extensive testing.

    I'll reinstall the app and activate the debugging option next time I run windows then share the logs on github - thanks again and congrats on your recent purchase!
