Cpu vcore seems to be running at 1.30-1.35v in cpu-z and the system is stable. Motherboards is a Gigabyte EP45-DQ6 with bios F12 (latest non beta). Runs the cpu fine and it also shows SSE 4.1 and VT-x in cpu-z, so no need to mod any bios.
I am going to do some tweaking later today to fine tune the voltages etc and see what i can push this cpu to. But i was wondering what people consider to be a good vcore for a 4Ghz overclock or higher.
And maybe what you guys tweaked in your bios. Vcore, VTT, MCH to get the best overclock.
Good you have joined Quad 4Ghz club.
To see what`s the lowest Vcore for 4Ghz I`d suggest you check at 440FSB, as a motherboard may need more and more Vcore for just 5Mhz FSB.
Tweak the MCH.
My P5Q Deluxe/Premium in auto can run an E5450 at low Vcore. So some other cpus, while the X5450 needed around 1.300V or a little more if I remember right. But that depends on the motherboard too.
A good Vcore would be 1.250 - 1.275V, it would not make things warm in the PC case.
Anyway, you have a QUAD running better than a Q9650 at a fraction of its cost.
