Miner keep closing or crashing after some time!
Why there is no 64bit windows miner?
it doesn't really have added value. windows and your processor are fully backward compatible with 32-bit. There will not be any speed advantage
The new native sgminer3s.exe should take care of your crashes when you were using one of the old cross-compiled versions.
I use native sgminer3s and got crashes ( approx. twice a day ).
