Overclocking for video encoding

Hi,

I want to set my system up with the best overclock for video encoding in Adobe Premiere elements 3.0.

E6300 - DS3 v1.0 - PC-6400 Ballistix

Should I be just going for the highest possible CPU level (~3.5GHz is my best using 5-5-5-15) or would it be more benefit sticking with 4-4-4-12 timings and pushing those as far as I can go? Or as an alternative drop the multiplier to 6 and push for a max FSB?

Which is more important in video encoding? CPU or FSB or timings?
 
Your CPU and GFX are the 2 most used for video encoding.

Getting the most from your cpu will give faster results than with your memory. Just watch out for bottlenecks when doing this though.

As long as 3.5Ghz is stable, your on to a winner. I have my [email protected] and encode a 700mb avi in 12mins flat :)

What do you mean by bottlenecks?

Its a term used for a phenomenon where the performance or capacity of an entire system is severely limited by a single component i.e CPU, RAM or GFX.

Good old Wikipedia :D

For instance, you may be able to get 3.6Ghz on your CPU but your memory will not clock any higher than say 825Mhz, leaving your cpu to only go as high as 3Ghz.

I have an Asus P5N-E SLI that has the option to 'unlink' the CPU/RAM Speeds to I can cut out the bottleneck because I can clock them to their highest speeds individually.

A lot of Motherboards dont have that option so increases the chances of Bottlenecks.
 
Ah ok,

I think at 3.5Ghz on a E6300 is good going, so I doubt bottlenecks are in play

The restricting factor will be the 7x multiplier
 
3.5Ghz for an E6300 is an excellent overclock :)

You may be able to get those timings higher if you throw some more voltage through them.

What voltage are they currently at?

Depends on what voltage you currently have it at the moment.

To be safe, I would not go any higher than 1.5v but check the temps are not too high either.

No point in having a [email protected] with idle temps of 50c+.

Keep the voltage of the ram at 2.2v as again, your safe with that.
 
Increase it to 1.475v and see if you can hit 3.6Ghz.

If it boots, you still need to be sure its 100% stable by priming it with Orthos or Prime 05 for a good few hrs.

Just realised your getting FSB Speeds of 500+:eek:

I cant get past 460Mhz on mine :(
 
ok, got it up to 510 FSB and it runs all benchmarks (PCMarks, 3dMark06) fine, but lasts about 4 secs on a blend test on orthos at priority 1

Where now?
 
Up the vcore to 1.5v.

Check the temps and if you can, feel how hot the NB Heatsink is also and run orthos again.

The chances are that it will still fall over so you will need to lower it back down to what you had it stable.
