Why not switch to another OS instead if you only have one rig you can use hiveos it's free for 1 rig but if you are using multiple rig go for simpleminer paid 2$ a month per rig.
Have you tried to use other miner? T-rex or phoenix?
I am currently using phoenix miner and I don't see the reason to change mining software. It is still working at stock speeds but i just can't figure out what was causing the crashes in the first place.
If it still works in the morning I'll try to move it back to 1850 on the memory and see what happens.
