Hey all, i'm very new at GPU overclocking, been a CPU overclocker for a while but GPU overclocking is new to me.
 
So i'm using MSI afterburner, and was able to get the core clock up to 1450mhz (aided by GPU Boost 2.0), however when strest testing, it only stays there for around 15 seconds.  After that it downclocks permanently to 405mhz until I restart the PC with stock settings.
 
Why is it doing that?
 
Here are my settings:
 
Core Voltage = Stock
Power Limit = 100% (can't go any higher)
Core Clock = +100mhz
Memory Clock = Stock (going to overclock this later, until this core clock issue is fixed)
Fan = Auto (runs at around 42%-45%)
Temps = very safe, no more than 45C.
 
Specs:
 
I5-4690K
Asus Z97-A
Corsair Vengeance 8GB 2400mhz
EVGA GTX 750 TI FTW
SeaSonic G series 550W PSU
 
If you need pictures, just ask.

Hi I don't know where to post this so can anyone tell me what  OC Scanner X  driver  is please ?   thx ps I use my cards for crypto mining .

That means your overclock was unstable and the GPU downclocked and will stay downclocked until you reboot. Solution: lower the overclock. Given you actually hard locked the GPU instead of a driver reset, I'd drop your overclock significantly and test with actual games like BF4, Crysis 3 or something that is very graphics intensive...not to include your typical MMO's for example. Those or more CPU biased.

Thank you! I actually figured this out yesterday and you were right.  I went down to 85% core clock with a 300% memory clock and am stable there.  (using EVGA's OC programs now)
 
So why don't these cards OC that great?
