Default Could I have damaged my 920? (VTT Vdimm delta more than 0.5)

I recently got my i7 920 and immediately jumped into OC'ing without looking online first. Bad idea I know, but I kept all voltage pretty much at default (or normal on my Gigabyte EX58). Problem is, I know my memory is rated at 1.65 and so I went ahead and increased the voltage on my memory without increasing VTT (I think it defaults at 1.1). So I was running with a difference of more than 0.5V between the two.

Could there have been any damage done? I'm reading this guide that tells me to keep the voltage between the two within 0.5 to avoid damaging the CPU.

I doubt there will be any appreciable damage unless you ran with a greater than .5v delta for quite a while.

Test it. If it's stable and still OCs as well as it always has, it's not damaged.

Stock is 1.2v, not 1.1, so even with vdroop, it would not have been more than the allowable delta. Thats the whole idea behind 1.65v being the max vdimm at stock vtt, why would intel specify voltages that would damage the chip?
