Should I try for 4.5?

post #1 of 10
Thread Starter 
Hello all, been browsing the site for a few months without posting but had a few quick questions. I am new to PC building/overclocking and just built my first PC about 2 months ago. Was wondering if it would be very beneficial to jump from 4.2 Ghz to 4.5

Here is my PC

i5 2500k @4.2 Ghz
Corsair H100
AsRock P67 Extreme4 Gen3 mobo
16GB G. skill ripjaws 1600
MSI HD 6870 Twin Frozr
Seasonic M12II 620w
Fractal Arc Midi

I do a lot of video editing and was curious how much of an improvement i would see in render times with the jump. Right now it is sitting at 4.2 Ghz with the voltage set to 1.29. To get that i has the mobo auto set the speed and i manually set the voltage and left everything else alone. idle temps are 27-33 range and load temps hover in the 46-52 range (load being 4 hours of rendering videos)

So would I see much of a reward and if so can i just use the auto set to 4.5 and manually change the voltage like i did with 4.2? thanks!

My only question is why stop at 4.5? I have both my roommate and fiances 2500k running 24/7 at 4.8 without too much of a voltage increase and with that h100 i do not think the heat would be an issue.

Edit:Add your rig so you dont have to write it down every time you want to refer to it

Try it and see. I always think that if people want to OC, it's go big or go home. thumb.gif

thanks for the replies guys, my big worry with going with too high of an overclock is my inexperience with overclocking. really dont want to screw up my CPU lol would i see a signifigant improvement of render times going from 4.2 to 4.5 or higher?

Do it, say you did it, and go back down. It doesn't make much of a difference in performance.

I also do a lot of video editing ( Edius 6.07 ) and have my 3820 OCed to 4.6. I did see better encoding times from stock to 4.3 and very little increase from 4.3 to 4.6. Do you use Intel Quicksync with your 2500K to encode H.264? I would OC it as high as possible keeping stability and temps in tact.

ok so i went with 4.6 Ghz and the vcore right now is 1.36 started off with 50 runs of intel burn test. after the 50 runs the max temps on the cores were 60, 70, 70 and 67. is this a substantial amount of time? also should i run prime 95 as well and for how long. are these temps about the norm for this OC. (also should mention in case it holds any bearing but i have the H100 set to the middle settting

I am assuming you did 50 runs on "standard" load? Even if it was just on standard 50 runs is plenty with IBT When I try to find a 24/7 stable overclock I go for 10 passes on Max RAM, and then 12 hours of Prime95 Blend. Then call it a day.

What is your ambient temperature of your room? those temps do seem slightly high.

Yes it was standard. its about 72 degrees farenheit (i think thats around 22-23 in celsius) ambient in the room. been running prime 95 for about 4 hours so far and the max temps on that are 57, 63, 62, and 62.

ok ran prime 95 for about 15 hours with no issues the highest temps reported were the ones above of 57, 63. 62 and 62. did some video editing and it maxed out in the high 50's. these ok temps?
