Overclocking and Encoding

[swaaye]

Has anyone ever experienced any sort of corruption of a encoded video due to overclocking? Not crashes, but perhaps mathematical errors during the encoding process.

I'm trying to diagnose a strange frame flickering that seems to occur on random scene changes on TV rips I'm working on. I can't pin down what's causing it. Overclocking is my next suspect though.

DVD -> XVid 1.1 thru Staxrip. Filters: TIVTC, Bicubicresize 0.75, autocrop.

I used to get random green pixels in my encodes if I had the speed set too high.

I encoded the same episode on my notebook's P-M 2.13GHz with the exact same settings. Looks fine. Will have to mess with the desktop at home and see what happens if I up the voltage more or slow it down 100MHz perhaps....

Did you use the exact same source? I had a myriad of problems with encodes before I realized it stemmed from problems during ripping the DVD.

No actually. I ripped the DVD again to my notebook. That's a good point and worth checking out.

get ocbible here OcBible] (http://www.octech.gr/forum/viewtopic.php?p=9033#9033)
and make some tests on your pc.
Download also super-pi mod and find if it passes 32M without problems.
then you can be sure that it can pass encodings easily.
for more stability test try prime(rock stable!!)!

if your oc with nv chips you can get some curruption. Intel chips or via chipsets do better. I cant say about the new nforce4 chips though
