I recently installed MSI Afterburner so I can monitor the performance of my games and overclock, but I was just wondering what I could set the core clock to, I want to get the best performance out of my GPU but I don't want to fry the thing.
It is an AMD Radeon R7 200 series, if you need more info let me know.
Thanks!
An r7 200 series is not really an accurate description. Regardless. Push it in +25 increments. Both core and memory but in all honesty I don't think you're going to get much.
Just changing the clock speed without messing with volts is not really going to fry it, but you will experience graphical glitches if you boost the clock too much without increasing the voltage. Boost the core and memory in small increments until you start getting graphical problems and then dial it back a bit.
You can't fry your graphics card with MSI afterburner. At worst you might hurt it over time with heat if you max out the thermal limit and turn off the fan.
I recommend using MSI Kombustor to stability test your graphics card, use these settings:

You'll be able to see if you are getting any artifacts in the bottom right corner. Anything other than 0/0 means that you are getting artifacts.
Do as Taliyah said, increase the frequency by 25 mhz increments until you get artifacts then start reducing it by 5 mhz increments once you do, until you reach a setting that doesn't get any artifacts in a 15 minute test or so.
You should also max out the power limit and increase the fan speed, this will let you graphics card boost higher automatically. Cleaning the card's heatsink with compressed air can also help your performance.
I have changed the core and memory clock to 1264 (core) 1671 (memory) and its hasn't detected any artifacts but I have noticed that when I play GMOD for 20 seconds on a map then the screen glitches out and I have to turn of the computer, could MSI Kombustor not be detecting some artifacts?
Those are pretty high clocks for first gen GCN cards, it's not stable for sure. Can you at least get GPU-Z and check which exact card it is?
GPU overclocking can be a bit of a crapshoot because one game/benchmark can run perfectly while another one will push it over the edge and crash. It takes a while to test it in different scenarios before you can be 100% sure it's stable.
Yeah probably. you could run a benchmark like Unigine Valley and manually look for artifacts.
What should I copy and paste in GPU Z
Yeah 3Dmark is good
You don't copy paste anything, it's just a little program that shows you information about your gpu and also gives you useful sensor info. Just show a screenshot of this screen:

Oh, so it's a 260x: AMD Radeon R7 260X Specs | TechPowerUp GPU Database
That would explain the somewhat higher clocks, i already thought it was one of the rebranded 7000 series cards. Looks like your version already came somewhat overclocked out of the box as the default for this chip is 1100MHz. Like others have said, try dropping the core clock in small increment and testing until you find something stable. Then once you've found a good core clock, you can move onto memory, I wouldn't do both at the same time.
The Witcher 3 and Furmark are also really good at stability testing.
