I call garbaldygook on the not tuned for Thubans, as the Octa FX's will have a 135watt TDP (thats 10 watts higher then the Thuban) at stock
not true at all, vdroop results in lower total wattage pulled, its healthier for your CPU.
Sow hat is so wrong with teh board i am not gettingit?
BTW some of you guys need education in voltage regulation, the MOSFETs have nothing to do with it, the PWM does and the tweaking for the PWM does. The PWm controls the output voltage no matter the condition of the MOSFETs.
You guys really need to see Intel, Vdroop is part of the spec, and almost 100mv in many cases(thats .1v) and that is becuase those CPus are really power hungry and need to be in good condition so the vdroop maintains this fact.
Here is why vdroop is there:
So wattage = power and power= current x voltage.
At idle you are pushing VERy little current rhough the CPU, so teh voltage can be higher, its really doesn't matter. But when you go under load, the current is increase in huge steps, in Intel platforms its 100A step. Do the math, voltage is dropped for an increase in current so that the CPu stays within TDP.
Ever think that is part of BD's spec? vdroop? its very common among high wattage CPUs. This board is tuned for BD not Thubans like i said before.
Now on Intel side we have somthing called LLC, load line calibration and its not very healthy for teh CPU and it does exactly what you guys are asking for, no vdroop.
BTw vdrop is part of every single voltage regulator on your board, its the difference from what you set to what you get. Vdroop is difference between idle and load.
If what i read is correct you guys are saying you set 1.5v and you get 1.54v idle and 1.47 load, then that is not natural, it should be more like 1.49v, if its raising that means GB has implemented some type of LLC for this platform, whether they care to tweak it or not for now, or whether they need to is not a question I can answer for you. What i can say that you should ONLY look at your load voltage, idle voltage means as much as idle temps, as in it doesn't mean scrap.
Remember font be scared of voltage be scared of current, becuase no matter how much you change voltage, current wont change.
FYI i do help GB better their products by doing a power user review. I haven't had time to touch this board becuase of llano launch but ill investigate it.
One thing to remember, b/c its not in the BIOS doesn;'t mean its not there.
Intel P67 boards released with 3 levels of LLC, now they have 10 through a BIOS update, and I have a BIOS with 33 possible LLC levels, of course consumer will never see 33 levels.Edited by Sin0822 - 6/29/11 at 3:56pm
