Hi everyone

*looks around*, first time I've been in here!

I'm doing some video encoding work...lots of it actually and I need to up the encoding speed of some of my older PCs.

There are three machines with very similiar specs that I just need more processing power for encoding on the CPU, they aren't for gaming, just video encoding.

Can anyone tell me what I should do to get some extra power out of them?

Thanks! :)


These are the specs (ABC, LM & RM are just to identify each machine):

core 2 duos and quads are easy to overclock.

But first you need to make sure you have a good power supply (i.e a good make and not some rubbish that no one with any brains would use) a good aftermarket cooler and a case with good airflow.

This is how you overclock.

Go into the BIOS

Switch off EIST, C1E

Raise the FSB by 10MHz save and reboot, if you get into windows then go back into the BIOS and repeat. Once you have raised by 60MHz test the overclock by running OCCT for one hour whilst monitoring the temps with real temp or hardware monitor. You do not want to go over 60 degrees c.

Once testing is done repeat the above. If you happen to get a BSOD whilst trying to boot into windows you need to increase the vcore voltage.

Only ever increase the vcore to the next available voltage and try again, if no luck try again if you get luck stress test with occt for one hour again whilst monitoring the temps again.

Onve you get to a overclock you are happy with, stress test whilst monitoring the temps for at least 6 hours, again you do not want to go over 60 degrees c.

You may have to lower temps on your mobo southbridge and northbridge as with raising voltages the same rules apply for lowering voltages. Only ever increase the voltages or decrease the voltages by the next available setting.

Thanks very much for your reply! :)

They are all Corsair 450W VX PSUs.

Wow that sounds fairly easly but longwinded!

I'll give it a go and report back! :D

It can be long winded. Look on google for other peoples overclock results with your CPU. Use that to base you target on. If they have 3.6Ghz out of the CPU for example, it would be fairly safe to try 3Ghz with a small bump in voltage, test and if temps are fine and its stable, jump another 100Mhz. Once you are within 20% of their overclock drop down to smaller increments, booting each time.

Also remember, just because they got xGhz, does not mean you will.
 
Agree with Oliver. Best I ever got out of a 6750 was 3.4. The best core 2 duo imo was the E8400 go stepping which I have in my old system running at a constant 4GHz with only what I stated above plus a small increase to 1.218v for the vcore.
