780GTX running 347.25 Previous versions of AB allows me to set any core speed (1215 stable) but the newest version limits me to 1145 irrespective of the setting. Im WCed and currently not even hitting 40c ingame, priority is set to temp. Any ideas if its a driver issue or AB.
Hm I can OC the same 1215mhz, did you try newer 347.52 driver? Also try to lower vram OC a bit, sometimes certain drivers are more harsh on vram timings and fail at higher OC. Im running stock 1500mhz or it fails quick with any driver or MSI AB, max I can do it 100-130mhz on vram (12-14gb/s difference), so I've always kept it at stock and max out gpu OC.
@Tj, I could put any number into the AB Core Clock slider but the card wouldn't go over 1145. I used DDU to remove everything NV, I uninstalled AB as well. I then installed 347.09 and AB 4.1.0 and all is good. Sine then ive used the AB voltage softmod to use 1.4mV and flashed the Bios so no more fluctuating core speed during gaming. Running 100% stable at 1241mhz at under 50C VRAM at stock, never bother to OC it.
Ive modded it since. I cleared the issue by a complete uninstall of all NV drivers and AB. I use 347.09 which may have had something to do with it.
Im still on driver 347.09 and im still using MSI AB v4.00. No need to change as all works great as it is.
