What is My GPU CLOCK SPEED

So about a year ago I bought a gainward GTX750Ti the card runs great no problems. But 1 day I decided on overclocking the card. I was going to use expert tool and Unigine valley to test the overclocking and temps. I booted up unigine valley and noticed that unigine valley said that the card's clock was on 1360Mhz but expertool said the card's clock was at 1228Mhz while running a benchmark. What is the card's true speed? Because if it's 1360Mhz it means it's already overclocked. Another question I have is if 72C degrees Celsius is normal while gaming because that's what the card runs at while playing planetside 2. Finally it would be very helpful if you could find the complete specs for the gainward GTX 750Ti which is the small one here's a link https://www.google.com/search?q=gtx+750+ti+gainward&client=opera&hs=dAD&biw=1920&bih=971&source=lnms&tbm=isch&sa=X&ved=0CAgQ_AUoAmoVChMIu5TzvMT0xwIVxewUCh3sYAS1#imgrc=7PARCDYanCBWwM%3A

I like Unigine Valley as a benchmark and stress test, but I don't believe it's clock speeds. Try GPU-Z to get a second opinion on your GPU's real clock speed. Remember there's a difference between Clock Speed and Boost Speed. Clock Speed is the default, and Boost is the maximum OC that the card will provide out of the box without manual adjustment. See here for more details:

So what is the real clock and memory speed that my gpu is running on while gaming?

At the bottom of GPU-Z, you'll see a box that says "Default Clock". That's your card's base speed as programmed at the factory. The Boost box *on the same line* represents the maximum speed that the card will upclock to. "GPU Clock" is probably the same as "Default Clock" UNLESS you've manually overclocked your card. GPU Clock shows the real base speed of your card. The Boost box on the same line is the maximum OC the card will achieve with whatever adjustments you've made.

EDIT: Posted after you put up the pic of GPU-Z. Looks like your base speed is 1085 Mhz, and you will upclock to 1163 MHz under load.

But isn't that a a slow core speed cause i've heard people with 750Ti's that have a core speed of 1300mhz while gaming and in terms of the memory why does it only show 1375Mhz there are sites which show that the 750Ti's memory runs at 5400mhz an example is this https://www.evga.com/Products/ProductList.aspx?type=0&family=GeForce+700+Series+Family&chipset=GTX+750+Ti

I've figured out my real speeds. Turns out the memory is running at 5500Mhz and the Core at 1163 as we saw before. Now since my card is already oc should I actually overclock since i'm getting like 72C degrees Celsius temps when playing games like battlefield. is it worth it?

So I have just overclocked my card and I run Unigine Valley before oc and after oc. I oced the card's core from 1163 to 1268 and the memory from 5500 to 5700. On the 1st test(no oc) I got 33.0 frames avg and temps were at about 72 Celsius and then I run the 2nd test and got 34.2 frames avg and temps were at about 74 Celcius. Why is the increase so small I was expecting something like 7-10 frames more

You applied about a 9% overclock. I would expect you to increase from about 33 fps to 35 fps with an overclock of that magnitude. So that seems about right. I usually find overclocking not to be worth the effort and risk, unless you've got a really stellar GPU/CPU (I miss my Q6600).

Just run the test again with 5800Mhz on the memory and 1280 on core clock and got avg fps of 35.2 this time. Anyway my temps are still pretty high at 75 Celsius. Got any tips on how to lower temps without getting extra fans or watercooling. I mean for a 750Ti I think 75 is a little too much it should be at something like 68 atleast, what do you think?

Well anyway you were extremely helpful and thank you very much. I'm planning to keep the overclock and clean the dust from my gpu because there is actually alot of dust in there I hope that drops my temps to 5 degrees celsius less.

I think NVidia officially start throttling GPUs at 70C (at least they did with the 6xx series.) I think the highest I've seen my factory overclocked GTX 670 is 72C. If I were you I'd back off a little bit on the overclock and shoot for 68-69C.

I opened my pc and noticed alot of dust on the card's heatsink it's 100% what's giving me these temps. I'm gonna get a can of air and clean it once I get one i'm also gonna put my pc off the ground on my desk, and anyways ambient temp in my room without air conditioning is like 32 Celsius
