Trying to correct CPU Speed on BIOS Rev. 2

[Abhorson]

I use a 2.53Ghz Xeon processor which, after upgrading the BIOS of my P55A-UD4P, registered @ 2.00GHZ. I changed a few multipliers in order to get my RAM up to 1600 (G.Skill issue) and my Processor up to 2.56 GHZ. I was wondering if by upping the settings it would add any additional stress to the processor and memory, even though they aren't much above their actual defaults? It's at a x15 multiplier, is that bad? If not, should I consider going any higher?

That isn't necessarily bad... It probably misidentified the CPU so used an incorrect multiplier - Similar to when my Q9450 wasn't officially supported on a 680i so booted with a 6x rather than a 8x multiplier. As long as it is stable, it doesn't make a difference. The same clock speed will roughly give off the same heat, if the QPI and NB is running at a constant speed. You can push higher if you want to, but I would look for tutorials first as it can be risky and damage components if you push them too hard, generally by raising voltages too high.
