What are you talking about? Nobody mentioned VCCIO but you.

And I've been running between 1.15v - 1.20v VCCIO since I built my rig. No issues yet.

There is nothing about issue. It's trade off to have lower v-core by increasing VCCIO voltage.

I think that happens to depend on the chip. VCCIO for me, only increases my RAM stability (more noteably my IMC stability). Especially when using higher vDIMM.

if I can get 4.6Ghz on 1.3v, I think I can get 5ghz on less than 1.5v

Mine is a Costa Rica, and it won't do 5GHz with less than 1.50v stable. 4.8GHz requires 1.43v to run stable. 4.9 takes about 1.46-1.47v.
same voltages as my 2500k here. 1.51 to get linx stable at 5ghz. 1.495 to be 24/7 casual usage stable.

Your sig says 4.5GHz, 1.30v though.

And you'd honestly be very surprised at how hard it is to break into 4.7-5.0GHz stable with low voltage.

mine at 5.0ghz with ht enable and rams at 1866 at cas 8. it needs 1.44 in the bios and load it goes to 1.465. temps never hits over 63c. it idles at 27c. my io voltage is at 1.15 volts and drams voltage is at 1.65. i think it depends on certain chips and somewhat of the motherboard. my msi gd80 board needs to be at 1.48 volts to be at the same setting.

after posting t his it occured to me that i never tried bumping vccio past 1.1v.
rebooted, 1.15 vccio, 1.495 gets me linx stable and max temps 2-3c lower. I'll take it!

Getting a Costa Rico chip doesn't guarantee a good chip. Having a batch that someone was able to get to 5ghz at x voltage does not guarantee a good chip. SB is not like the past chips where batches almost always guaranteed good numbers. I have had two 2500k's and three 2600k's and some would do 5ghz at 1.41v and some would not. It's somewhat random on what their capable of doing and what their max multi is. I also found that a couple of the ones that would do 5ghz at 1.4+ voltage stopped being able to get 5ghz after awhile without adding more voltage. As far as adding more VCCIO to get a chip stable should mean that your ram was not stable even if it appeared stable at first. There are a few good guides on what the various voltages effect and it usually a combination of voltages that will get 5ghz stable because you have various factors. A chip might not have a good memory controller that holds it back until you increase VCCIO which then makes it stable. At the same time, sometimes a chip will not like too much voltage and will appear to be unstable even though you are adding a lot of voltage to it. You have to fine tune it and getting above 4.8Ghz usually means a lot of tweaking. I am not saying that there are not some chips out there that will do 5ghz with low voltages, just that a batch number, where it was made or a particular voltage does not guarantee a 5ghz overclock. This is why you will see folks binning chips and selling the same batch numbers at various overclocks and various voltages.

Mine needs 1.42v load for 4.8GHz, I switched it up a bit trying to get a bit more out of it last night.

I'm running 102.3 fsb x47, which gives me 2182Mhz on the ram @ 8-10-9-24 1T.

I also plan to skip over to Ivy if it pans out early next year.
