so i have a radeon hd 7790 1gb @ 1075 MHz, and recently i have been playing bf4 beta. i tried to overclock my gpu to 1200MHz (which is the max) i turn up the fans to 75%, which is more than enough to keep it below 40 degreess C. i also put up the power draw to +20%. but for some reason my game will suddenly get this huge lag out of nowhere. someone told me it was because of the card not having enough power, but i have a 650Watt psu, which is more than enough for my system, plus, i put on the +20% power draw thing on in CCC. why is it doing this?
All cards OC differently. You should trying resetting the card to default settings and slowly bump the settings up until it becomes unstable, then revert back to the highest stable settings. Your particular card may just not be able to do 1.2Ghz
it has before though in games like skyrim so why shouldnt it now? plus i have to do a full restart if it doesnt work... so it may take a while to get just right...
I would assume it worked on Skyrim because that game may not be as graphically intense as some other games. What games are giving you trouble and what's the load on the GPU?
Also did you do any OCing to your GPU's memory?
the memory is always at the max clock, 1600. the only games giving me trouble were BF4 beta... thats it. but i dont really have many more graphically intense games. only skyrim, and MW3. i havent checked the load on the gpu. now that the beta is over i cant really check though
You're card will most likely not be able to run BF4 above Low settings in beta anyways. A lot of higher end cards were having issues performing worse than they probaly should have.
More importantly, bf4 is very cpu intensive, what CPU do you have? Chances are that it might be what's causing the problems.
i was actually able to run the game on all ultra and maintain a 60fps on an empty server. change textures to high, and leave the rest on ultra, and i can play on a 64 player server 60 fps.
btw i have a fx-6300 @ 3.8GHz
But since the beta is over it's too late to see if any of those suggestions would work. It's suggested a lot that these problems will be resolved by the time that game is officially released and your setup won't act up.
Since BF4 was the only game that was actually causing you problems, it's likely that there is nothing wrong with your card and it was just BF4.
