Overclocking will void the warranty on the CPU if it was to fail due to the overclock, but if it was a overclocked system by PCS there is two options.
Go into the bios and one of the screens should be a O.C Profile screen, usually PCS would have saved your overclock settings to one of the profiles so try loading the profile up.
Failing that I believe they may have been posted on your notes from testing/QC if not do a quick search of the forums i swear they got posted somewhere, but you best bet is to find the settings used on your machine specificly from the tech notes as these are known as stable on your machine.
If you can't find the details either give them a call in the morning or open a ticket to tech from your admin pages and someone will pick it up tomorrow and reply.

As mentioned in my last post it is probably best to contact PCS and clarify as the above settings may be stable and working on silkysean's machine but Killzoned may be slightly different for various reasons..
The settings may have been tweaked slightly per machine for stability reaons as even though the same components are used they may behave differently to being overclocked.
Thanks for the response, By any chance LFFPicard are yours Overclocked? As we have similar specs
