Back on the 15.9.1 BETAs, and cores are back locked at 1040Mhz.
What a faff on ive had though, uninstalled Crimsons, but after they uninstalled, was just stuck on a black screen, tried the old enter a few times to restart, wouldn't have it, mouse just blinked 3 times as normal when restarting etc..., but it wouldn't, had to hard restart, start windows normal.
Crimsons were off, so installed 15.9.1s again, went in fine, but after the restart, windows just loaded up hung, had no mouse pointer, just my desktop, couldn't do anything, CTRL+ALT+DEL, nowt, hard restarted again, then after the spinning balls, went into a bloody CHKDSK, after that finished and it had restarted again, windows loaded to a black screen, so had to turn my monitor off/on to get the picture, where i was greeted with the Xfire detected box, and all working fine, phew.
Don't know, as i wouldn't be able to see the OSD without it, so wouldn't know if the cores were locked or anything.
EDIT: Just Tried Alan Wake again, cores lock to 1040 straight away.
