Could someone explain what does diff1 and diff4 mean please? I tried to google and got exactly zero (useful) results.
When I change the settings from actual to diff1, it looks like I get zero accepted shares in status tab, but the number in devices tab shows something.
Are you using bfgminer? And are you mining a scrypt coin? If so, bfgminer does not report a valid number for total miner diff1 shares. I'll be changing the way this is reported in the next version.
A diff4 share is equivalent to 4 diff1 shares. Your pool gives you work of a certain difficulty, which you must meet or exceed to have the share accepted. The higher your hashrate, usually the higher difficulty shares you get. But you get paid in diff1 equivalent shares, so a diff4 share should earn the same as four diff1 shares.
Where does CGwatcher add an entry to start on Windows start?
I seem to have 2 CGwatcher that tries to start at boot and can't find how to disable the older
I would suggest using System Configuration (Windows key + R, type in
msconfig and press Enter). Go to Startup tab, uncheck the old CGWatcher startup entry. The System Configuration shows combined startup entries (registry + startup folder).
If you want to remove the entry, I'd recommend using
Autoruns, which allows you to disable or delete startup entries. It provides a comprehensive list of all of the places an application can set itself to start automatically.
In the registry, CGWatcher creates an entry in HKCU\Software\Microsoft\Windows\CurrentVersion\Run for the current user, or HKLM\Software\Microsoft\Windows\CurrentVersion\Run for all users. You'll probably need to run CGWatcher as Administrator to save or remove the HKLM entry. Previous versions of CGWatcher would try to save to HKLM, and it would appear to work when in reality Windows actually creates a virtual registry and sticks it in some WoW3264Node key (I can't remember where exactly). If you're familiar with the registry and regedit, you could do a Find for CGWatcher.
