What is the typical safe voltage limit for CPU/NB on deneb C2 x3/x4

post #1 of 6
Thread Starter 
What is the typical safe voltage limit for CPU/NB on a deneb C2, in my case a x3 740 -> x4 40, which seems to OC very well so far.

Technically it's safe up to the same limit as CPU vcore: 1.55v. A lot of people run below 1.5 for various reasons though. You may or may not see scaling past 1.5, too.

1.5-1.55V, similar to the CPU.
But you will probably never have to go above 1.4V, NB really never requires as much voltage.

All the 45 nm ones, anyway. Thuban is generally thought of as slightly less tolerant of voltage than Deneb, too. Chew, or Tater Tot, maybe both of them, have said that some degradation can occur above 1.475v with Thuban, for example.
