Today I have tried to overclock my MSI GTX 750Ti to get a bit more performance and get the feel for the overclocking, I spend about 2 hours, running valley benchmark and playing around with the core clock and memory clock until either the benchmark/drivers crashed, or I noticed any white dots or something wrong with the picture. I have managed to get from stock:
Core clock: 1176Mhz
Memory clock: 2700Mhz
to
Core clock: 1421Mhz
Memory clock: 2945Mhz
I have also changed the fan curve because the card was getting above 70 and I never had it go above 60 on stock clocks. The memory clock is smooth, it stays at 2945 all the time, but the core clock jumps from 1408 to 1421 all the time, not sure if that's normal, I haven't touched the core voltage because I heard that you can damage the GPU if you put too much than needed and I'm not 100% sure what it actually does. my question is, will I see any performance gain with this overclock and is it worth it for the extra temptures and tare? And could I go any higher and do I really need to adjust the core voltage? If I do, I'll do a bit more research on it and I'll try to adjust it.

The GTX 750Ti is a high performance/price ratio, compared to higher cards it is quite weak, but it is good for a low budget card. With the overclock you gathered, it is quite impressive, I didn't know a 750Ti could get such a decent overclock. Yes, it will lower the lifespan, but no doubt, the 750Ti will only be around for budget gamers for a short while longer, before something like the 950 is needed at minimum.

You could go higher by raising the core voltage, but it isn't needed with the overclock you gathered.

I'm currently doing computer engineering at college and I needed a small budget PC that I could transport it between my house and college which I ended up with a Dell Optiplex 960 SFF because the case is litterly just a big bigger than a normal laptop screen. I only need the GPU to last for 2 years because that how long my course is and after that I will most likely to sell it. I have managed to get the memory clock to 3002Mhz without any issues but the temptures started to raise and raise and it got up to 82C which at that point I had to stop because it wouden't stop raising (most likely due to the small form factor case, if it was a normal ATX case with good cooling, it wouden't reach that high), the card is a lot more capable than my overclock if someone has good cooling, but is the core clock jumping from 1408 to 1421 and back to 1408 normal? I runned the benchmaek for 10 minutes and it was doing that for 10 minutes straight. I only really need the card for 2 years so I'm willing to really push it since the 750Ti's normally live for 6-7 years on stock clocks.

Yeah, I believe the clock speeds jumping around is normal. But yeah, the card is made to stand around 80c, so that isn't an issue. As long as it stays below 70c I wouldn't worry too much. Anyway, the card will last you the 2 years, if it was for gaming then it most likely wouldn't, but for general use and engineering then it shouldn't matter as much.

Everything is fine, although as you said, better cooling means a higher overclock, but that won't make too much of a difference, maybe a 1-2% performance increase at max?

The issue is the really small case, I borrowed my friends thermal camera and when my CPU is under load (Xeon X3323) the fans would push the hot air, straight into the fans of 750ti and I could see that the hot air from the CPU, cycled 6 times thru the 750ti before it finally exited the case. I have a HP pavilion p6 series as my gaming PC and the PCI slot is above the CPU, so the GTX 980 I got inside it, never had this issue. Which is why I was thinking to water cool the 750ti because I power the small form factor with EVGA 430W 80 silver, and the PSU is so big, that it has to be screwed to the side panel, out the case, so the top half inside the case is empty from the previous slim stock PSU that was in there, so I would have room to fit all the water cooling stuff, but nobody makes water blocks for 750ti because they don't normally reach high temps so there is no way to water cool it unless someone has the whole PC water cooled and they want to add the 750ti to their loop, I haven't yet measured the stock heatsink so I'm not sure of there are generic heatsinks.

After playing a game for half an hour on stock clock and overlocked clocks, these are the results:
Stock clock:
GPU Tempture:
Min: 54C Max: 61C
FPS:
Min: 43 Max: 49
Overclocked (I did get a crash in first 5 minutes so I downclocked memory & core by 2Mhz and did not get any more crashes after that):
GPU Tempture
Min: 60C Max: 72C
FPS:
Min: 49 Max: 62

Litterly my minimum fps when overclocked was the maxmium on stock clocks, I am more than happy with the results, the temptures are a bit higher but nothing to be worried about. I though that it's going to be very small noticeable diffrence, but I could tell that the game was running a lot smoother when overclocked, the card is a lot more capable than my clocks, but for me, it's enough and propably in the future I will overclock it to the max just for self-learning but for now it's fine for me.

Just proves that you have a very good, lucky GTX 750Ti, it is some great FPS increase on that overclock, and with it being stable without increasing the core voltage is even better. Nice job! :)
