Any reason to push my i5 2500k OC past 4.5?

post #1 of 9
Thread Starter 
Hey guys,

I will be getting a 780 soon for gaming, which has made me consider OC'ing my CPU even more. Currently I'm at 4.5Ghz @1.360V, according to CPU-Z. After hours of gaming, I haven't seen any of my cores (#2 being the hottest) get past 70C. I am using a Hyper 212 EVO, and probably won't switch to water until my next CPU upgrade.

So for gaming, is oc'ing past 4.5 worth it? Is 4.7 going to have any significant increase of fps in games? 200mhz doesn't sound like much, but I hope I'm wrong! And if 4.9 is even achievable on air, is that worth it and should I go for it? Or should I go with 4.7 or stay at 4.5?

Thanks!

No you will not see any perfomance gain by going over 4,5ghz. Its not like your cpu will be bottleneck at this speed. So dont bother stressing your cpu with more vcore. Just put your 780 on and enjoy your gaming.

By the way, is 1.36v a bit high for 4.5? I could've sworn I set the vdroop lower, but I haven't checked CPU-Z in a while. Well it's stable and I get good temps so it doesn't matter, but I was shocked for a second.

Thanks smile.gif And I will try to get a good overclock on my 780, so it at least matches a Titan thumb.gif

Unless you do stuff that would really use the extra 200 mhz like encoding videos and stuff. But if you are only gaming mainly beside the usual web browsing I would not worry about it.

I do make an occasional video for Skyrim mods, but I thought the GPU does that?

No its mostly cpu and the memory subsystem like fraps. But with my 3570k at 4.5ghz I only get at most 50% cpu usage while playing and with the mods i use pulls between 1 to 125mbs loading stuff.

It is on the high side but if 1.36v is the vcore you need for 4.5ghz there is nothing you can do. Ofc you can try to lower it if you have not fine tuned it.

Thanks for the help guys smile.gif So even a 200-300 mhz difference wouldn't be more than 5 fps in games? Or help in video editing?

Doesn't hurt to see if you can get 4.7Ghz with 1.4v.

Give it a shot.thumb.gif
