Does overclocking increase performance?

Hi there, since i'm stuck with my current PC for a while i taught i'd try to overclock my processor. I overclocked my graphics card but all i got was 2 fps extra, it wasn't worth it, so i reverted to stock. I don't really want to increase my gaming performance since i can run most games max at 30fps (locked), i just want to increase my video editing performance. Since i record my gameplay the videos are huge and i have to edit it with cyberlink powerdirector, but it just moves really slow.. Would overclocking my CPU fix this? If so, are there any good overclocking software besides AMD Overdrive? (It doesn't work) It's an AMD Athlon X2 245 btw. Thanks to anyone who can help :)

I run Powerdirector to edit my HD driving videos and found that (upgrading) the GPU made the most difference.

OC that CPU might shave a couple seconds off a 30 minute video. (Not worth it IMO)

I have used Powerdirector with 3 different CPU's, one OC, and two different GPU's. The single core was crazy slow with movie rendering. The tripple core got me down to reasonable render times. Upgrading my GPU from a 210 to a 560 made a quantum leap in render speed. Upgrading to a 6 core @ 2.7Ghz bumped the speed a little more ( but not a whole lot) and overclocking the 6-core to 3.4 gave another small bump in render speed.

In my experience, the GPU is doing the heavy-lifting with powerdirector.

What GPU are you using and have you enabled hardware acceleration?

OC was able to increase the ability for video editing, but need to see the software used, vegas / adobe premire / Power director / ect, every software has a different acceleration, there is a CPU and GPU are some even do both

- sony vegas pro 11 will use GPU video editing software has GPU-accelerated
- Vegas 9 uses only the CPu for rendering.
- Premiere Pro uses the GPU for some effects the video preview
- After Effect use GPU
- Power director 7-8-9 use CPU (90%) and if ran with richvideo hasGPU-accelerated
- Edius use CPU
all that from my experience using powerdircetor 7/8/9, Magix video pro, after effects :D

@Z1NONLY I didn't know that, i always taught that the CPU was used for video editing (i7, bulldozer), thanks for the info! My graphics card is an ATI Radeon HD 5770, i'm guessing this is good enough for video editing right?

@henydiah I also didn't know that, thanks for the info! :D  I use powerdirector 10, guessing this one is also CPU hungry?

yep Power director need high clock CPU and stable and cool temperature because will ran 90% hot hot :D

Your CPU, an Athlon II X2 245, is extremely weak for these tasks. Do you have any funds for a CPU upgrade? As long as your mobo is not limited to 65W CPUs, only $60 (with the $10 off promo code) will get you another core and another 300MHz: http://www.newegg.com/Product/Product.aspx?Item=N82E168... and $90 (plus a $15-$20 cooler) will get you 2 more cores, 300MHz, and L3 cache: http://www.newegg.com/Product/Product.aspx?Item=N82E168...

Not sure on this, but I think Power director uses "CUDA" hardware acceleration and may not take advantage of an AMD GPU as well as a "CUDA enabled" NVIDIA card.

(I'm running a GTX560 ATM)

With the GTX560, my X3 Athlon was going to 100% when rendering. (Probably holding back the card some) With my X6, I render between 70 and 90% CPU usage, depending on the effects and format I'm using.

try render DV 60 minutes + effect to AVI and see your CPU usage and your GPU will stay

@henydiah So if i overclock the core clock, memory etc would it have some performance increase? I don't have to worry about temperatures, i don't have a water cooler but i got some new case fans and they are in the right places so i don't overheat.

@jtt283 Nope i'm all dry on cash. I just purchased a new phone, some speakers and a new monitor (about $600 USD in total).
I'm a student so i don't work, this was just money i saved from lunch, birthdays etc so i don't think i could purchase one for a while..

@Z1NONLY Well what if i install CUDA would that work? :p 
Or is CUDA designed specifically for Nvidia cards?

of course your time will be short than before ... but i would worry if you don't have good cooler cpu :non:  .. and fan case just help air flow, it's different with cpu cooler

Well i have a stock cooling fan, but i have about 3 fans in my case, so it never overheats. Ever since i got them, my graphics card used to go up to 70+ degrees on full load, now it's around 48-50, and i have one of these facing my cpu as well (the guy said it's sure to keep it cooler). So would this be enough?

@amuffin shocker :p

I don't recall anything about richvideo with my PD9. However, going from the 210 to the 560 (GPU) is the biggest jump in render speed I have seen, so PD is using the GPU for sure.

With the 210, my 3-core wasn't being taxed that much and my render times were -going from memory here- double real time? With the 560, all 3 cores would go to 100% and my render times fell to about 120% of real time.

When I upgraded to the 6-core, my render times slid to about real time. The OC from 2.7 to 3.4 has me consistently under real time but only by about a single-digit percentage.

This is all comparing the same basic "effects". I generally just flip, enhance, and chop the ends of the time line.

@henydiah I never overclocked the CPU. The clock speed is 803.75 MHz and the bus speed is 200 MHz.

@Z1NONLY In PD10 richvideo's active as default so i'm assuming it might have been in PD9 also. I want to do the same things as you, basically crop and edit them together, literally thats all i want to do.. Movie maker worked great (lame i know :p  ) but i started using PD because i heard the quality is better, i'm still waiting to see that happen... :|

Sooo, since it's GPU accelerated OCing my processor won't make that much of a difference? If it's at least 5 seconds less loading time after i trim a video thats good enough for me..

Yeah, CUDA would be the direction I'd go in for video editing . Adobe to keep support costs down detects the FGPU used and de-activate sit if it's not on their very short list of tested cards....you can unlock it tho.

Unlock it using instructions here

Butt ,a gain, you'll need a nVidia card

But my graphics card is an ATI, i don't think that link would work for me :/ 
And i had a GTS 250 but i sold it, since the 5770 was about 5 fps faster, i regret it now -_-

Well like in my OP, whats the best OCing software? My motherboard is a Biostar mcp6pb m2+ and i don't think it can overclock through bios..

For GPU
Msi Afterburner

For CPU
BIOS, don't use software!

I'll keep my gpu stock, but i did a minor fan increase in Catalyst.

I don't think i can do it in bios, it's very complicated and i have a feeling i'm gonna kill something. Last time i tried my PC stopped working, i don't want to go down that line again :(  Whats so bad about OCing through software?
