Doh!
I just realized I was running 12.4 version.
Updated to 12.5, so far so good.
@Valgar nicehash released new version of the miner with updated CM miners, check if it helps.
Thanks for the tip! I'll give it a go, also for some reason Windows had just decided that after 3 weeks of mining it would block the miner which is why I got disconnects, thanks for the help Claymore!
Edit: seems to be working much better now, my 280 which has stability issues before seems to be better too.
