Hi 8pack, just built a Asus x79 Deluxe mobo+4820k combo+TeamGroup 2133 ram and l must say its a very good combination, stable overclock at 4.6ghz 1.344v>CPU-Z ram at 2133mhz for 24/7 running with very good temps Custom H2o Cooled.

Your help needed to see if l'm on the right track, to find the offset voltage needed see example below -

4820k 3.9ghz at stock at 100% load say l need 1.232v[CPU-Z], them OC'd at 4.6ghz voltage need is 1.344v[CPU-Z].

Do l just take away stock voltage at 100% load>1.232v from OC'd voltage at 100% load>1.344v=offset voltage +/-.

1.344v - 1.232v=0.112v is your offset voltage.

So in this case offset would be +0.112v, Bios offset would be nearest setting.

As it worked out my offset voltage is +0.085v giving me 1.344v[CPU-Z] seems to be ok and stable, temps good.

Thanks,
Oldphart.
 
Thanks for that 8pack, just ran 3DMark Vantage benchmark -

i7 4820K:4.6GHz / SLI 670:1214/3030 > H2o Cooled.

Results - Puts me at 22 overall first run with slight overclock on GPU's just to see how she faired.:)

3DMark - 44812.6 / Graphics Score - 51245.3 / CPU Score - 32553.5

For Vantage and dual card you benefit from going dual channel on RAM. Helps CPU score.

Right thanks again, but more than happy with the score. I remember you saying 2133mhz is the sweet spot for x79.

Using TG Gold 2133 - 10-11-11-30-1T seems to be my best timings at 2133mhz for my ram using RealBench to test.

As 2400 was out of stock when ordering.

But the ram will OC to 2400 - 11-12-12-30-1t 1.650V and stable would l get any benefit at 2400?

Thanks,
Oldphart.
