**Official** Core i7 860/870 overclocking thread

One thing I find interesting is XMP profiles.

I am expecting a barrage of "Don't use XMP you FOOL, that's for NOOBS!", right about now.

Just here me out.

I have no problem with using XMP. I would like to gain a bit more understanding of what exactly the XMP profile changes.

I found this page at Intel's site:

http://www.intel.com/Consumer/Game/extreme-memory.htm

If you open one of the PDF's on the right of that page it lists some memory kits that are "Intel" supported.

Ok, so Intel supports XMP, and my Corsair Dominator GT's are XMP equipped and Intel badged.

When I enable XMP Profile, my VTT is raised to 1.35V. There is no problem with stability. I have run 20 passes LinX and Prime95 was stable on blend for 12+ hours.

So, if Intel will badge and support XMP memory kits, clearly 1.21V VTT can be surpassed and is supported.

What do you think?

I will be posting here and EVGA forums soon with my latest OC results. Nothing amazing, and I might need some insight from some of you.

It has to be higher. My G.Skills can't do 2200 unless I up my VTT to 1.36V.

I'm surprised that the maximum "safe" Vcore is 1.55V - not complaining though.
