I'm a novice to overclocking. I've built a system with i5 3570k and Asus P8Z77 -V deluxe. The basic i5 takes 2h 15m to encode a typical Bluray video.

I overclocked to 4.1Ghz and the same video was marginally slower. I had also installed RealTemp. Reverted to default and during encoding the i5 went up to 4.15GHz, so marginally faster than the fixed overclock.
Realised I have to go to 4.5 for noticeable increase in speed but not done it yet while waiting for hyper 212 EVO and second fan.
It's worth bearing in mind the maximum Turbo speed. Does this vary from processor to processor?
I put OC tuner on X.M.P. but will I have to put it on Manual and increase the voltages myself to OC to 4.5GHz?
Do you have to increase the Vcore every time you increase the multiplier?
Any help much appreciated.

You do have to manually increase the voltages yourself when overclocking that high.

Typically you will increase the core multiplyer, and also increase voltages to whatever temps you can afford (more volts = higher temp) and if it is stable, you start gradually reducing the vcore to slightly higher than what is stable (makes it more stable, but gets you so you don't have a higher vcore than what you need).

Now overclocking should in theory should make it faster, but if it was only slower by a few seconds, then this is easily margin of error. Also to my knowledge some video encoding is now done on the gpu rather than the cpu now, so check to see what your encoding program is actually using. If it is using the gpu, changes to the cpu speed won't really matter as much as overclocking the gpu would.

Ah yes, I didn't think about the GPU. I'm having problems with my graphics card (an AMD Radeon HD 7700 Series, 1GB) which keeps freezing, maybe 2 or 3 times an evening. It freezes for 5-10 seconds, then the screen goes blank for a similar period and then I get a message that "the display adapter has suffered a serious error but has recovered".

I updated to the latest driver but it's still the same. It's only 9 months old so I could send it back to Amazon I suppose. Not sure if that model is overclockable. If I exchanged it what would be a good choice to replace it with, at roughly the same level?
