Do you have to OC both GPU clocks together to get to higher results?

Hi, so is it mandatory to OC the core clock if you only want to OC the memory clock? For example, right now I have +61MHz to my core and +300MHz to my memory, do I have to increase the core clock if I want to reach somewhere say...+500MHz? Or can you only reach a certain amount of memory clock at a certain core clock? Also, do I absolutely have to increase the voltage if I want to get higher than where I am right now? I prefer to get to the highest possible without increasing the voltage, so far I haven't added any voltage and it is running stable at those clocks with zero problems. And yes I know that increasing the memory clock has little effect on fps and that core clock has more benefits, I'm just doing this for fun really. I don't know about OC as much as I know about GPU stuff, so that's why I'm asking. Temperature shouldn't be a problem for me, so don't worry about that part for OC'ing, my GPU never exceeds 55C and my CPU never exceeds 47C, my system specs is in my signature.

Also, I might be getting a second GPU in the future, is it necessary keep both GPUs at the same clocks? Or can they run at different clocks while playing games? Because most of the time I may not be using my second GPU, either because it's not necessary or SLI is causing issues within the game. I just would like to know if I can keep my first GPU OC'ed and keep my second one at stock(as a backup), would it cause any problems if you run two cards in SLI at different clocks?

Thanks in advance.

First off, yes you need the two GPUs in crossfire to be at the same clock.

About your OC question, generally you want to increase clock and memory together. You can increase them separate amounts but depending on the game, you may or may not see results. Certain games will respond to memory overclocks very well while others will like a higher core clock. Overclocking both at once ensures overall performance is better.

Instead of focusing on memory just do the core clock. Increasing the voltage a bit for more core clock wont hurt and you should waste your time on the memory for no reason.

In an sli config, the cards will run at the lowest clock speeds of the two It is advisable to get the same exact card.

I'm not looking to increase my performance, like I said, I'm simply doing this for fun and to ask the questions for straight answers. I'm already at 60 fps with GTA V and Battlefront at 4k ultra, so no point of going further with the core if the highest refresh rate for 4k is 60Hz.

Yeah there is no point.... If you want to do it for fun, increase the clocks w/ voltage so you get the experience then revert it.
