I am the owner of laptop MSI GX 740 with Mobility HD 5870 and I have a little problem with drivers. Every driver I install works fine but I can't overclock card at all. Every time I try screen starts to flicker - I can overclock only on orignal driver but it is very old version (10.x or even older) and I can't use it on newer games (e.g BF4). Maybe there is a driver only for HD 5870 or you encountered this problem in past and managed to fix it?
Windows 7 Ultimate 64 bit
Thanks for any help,
