Hey I downloaded the Dell k4000m OC and flashed. I got board mismatch but still worked. Mine is HP. I cannot clock higher then 920 on core else my driver crashes. Temps are fine 66-71C. Also when I did clock to 900 it wouldn't go higher than 888 even on high gpu load. Thought it was memory but still driver crash. I have also noticed that it's a lil more laggy when dragging windows. I've seen on other forums that it can get up to 980-1000 and possibly higher. I have my original HP bios if you wanna just unlock that for me I'll buy you a few beers if you think that'll fix my issues lol.
