Maximum safe QPI/VTT i7 2600K?

post #1 of 3
Thread Starter 
Hey guys I have been having some problems getting my system stable and I want to increase my QPI/VTT this time to get a little more juice into the DDR3 controller. Given the fact that i am using a 1600mhz DDR3 module, I was wondering for an i7 SB :

1. What is the maximum voltage i can safely go for QPI/VTT?

2. What is the recommended QPI/VTT for 24/7 stability use?

I have no intention of overclocking my RAM and I just want to get my system stable and BSOD free. tongue.gif
Thanks in advance!

Try not to go over 1.24v period.. for some reason my chip behaved differently with high vccio on my M4E (seems to degrade imc somewhat fast) vs on my older ud4 where i had vtt/qpi set to 1.16-1.18 for 24/7 and my chip didn't budge in terms of stability or anything (never really showed signs of degradation of imc)

For 24/7.. try to get it as low as possible.. you aren't really going to need more than stock for most memory configurations.. but bellow or at 1.14v is ideal (past this point, usually there isn't much scaling anyways unless you are working with hypers or something comparable)

Some of my chips stop booting and black screen if vccio reaches above 1.24.. some bellow that... i had one i remember putting 1.3v in.. (it died, but probably not just because of the high vccio.. i had a high everything)

Ahh alright thanks for the tip. But I heard that such a high VCCIO is only applied to the first gen lynnfield systems right? Odd that it should burn out or degrade in such a way because some other OCers i know don't seem to encounter this kind of problem.
