GTX 750Ti 4GB problem

[oto.ulrich]

Hey guys, so I've recently got a not too much used GTX 750 Ti 4GB OC from a friend, it runs just fine but whenever I use a GPU detection software it shows me only 2GB of VRAM instead of 4GB. Also GTA5 showed me only 2GB when I looked in the settings. I'm not really good at these things, can someone help me? Is it a software or a hardware problem?
Thanks
Oto

post your voltage, post your CPUz screenshot too.

I removed all the OC I had, now I have everything on auto. for the CPUz wait

OK while it's not the best cooler it's not the worst - I'd say your temps are still too high. If it's making good contact with the CPU and a small amount of thermal paste was used, you are getting way too high of a temperature reading.

so, make sure the cooler is mounted correctly, make sure it has good airflow through the case (if it runs WAY cooler with the side panel off the case, you aren't getting enough fresh air in there).

Typically I'd expect to see that CPU at 3.2 ish with little to no voltage bump. Every chip is different of course.

Ok I'll take a look inside the case.

So I was inside the case, got to know that 1 of the 4 fan pins wasn't in place correctly and I replaced the thermal paste. Now I'm getting 35°C idle temperatures

that's better, now before you try and OC it again, stress test it and see what the peak temps are like. That way you have a comparison.

Lol thank you soooo much man, now I'm running GTA 5 (as a stress test) at 55°C!

alright, happy gaming, keep your temps in check and you'll be playing for a long time.
