DFI voltage table

Got bored today so i made this CPU voltage table:

Hope its useful to someone :)

EDIT: Made some corrections to the table

good job

Thanks a lot, usefull contribution.

One of the problems is that even with the math done, the voltages reported in BIOS are not in line with the table. It seems that the higher multipliers do not always produce higher voltages. For instance in my testing 1.400x126(1.764), 1.325x133(1.762), 1.300x136(1.768), 155x113(1.752) all result in the same 1.72v reported by BIOS and everything from 1.648 to 1.680 reported in CPUZ. It is good from the start, but it might be advisable to stick with multipliers of 123% and lower.

Ive noticed that using lower voltages and high % seems to have a limit of 1.4V e.g 1.150 and 126% gives just under 1.4V

thx realy usefull table

Good job...looking for something like this. Too lazy to make my own :clap:

WOW, great work.. That must of taken some time.. Very useful for sure... How did you keep from getting all those different numbers mixed up while typing that, LOL?

yea, that's true but the table is here not 2 tell u the exact voltage but +/-.

:D Here the same - 12 x 279 with 1,500 x 123% ist 1,77 in Smartguardian, 1,776 in CPU-Z and 1,792 in CBI so I think it is somethin' between 1,77 and 1,78 real but normally it should be 1,845.

But I recognised the board is undervolting even no special vid is used so maybe this comes from the undervolting issue.......... :confused:

:toast:

Yea DFI is undervolting but it holds the volts stable.

has anyone noticed that the volts go up considerably when you stress the cpu? For example I get 1.62v @ idle and 1.7-1.73v @ load

:D Can not confirm - got always extrem stable volts at all loads - maybe Your PSU is too weak ?

^^, it should b ur PSU, I had/have very stable volts on MSI K8N Neo 2 & DFI NF4

I had the same issue with my msi neo2, when i stressed the cpu the voltage raised, but at the DFi NF4 it is rock stable maks 0.01 volts variation... now thats awsome :banana:

Even though some of these settings don't physically translate into usage, the table serves as a good base for any new user. Great job.

Putting in use Excel,

I didn't use excel, i laboured over many hours to create this ;)

Great work. Now, can someone mod the bios so that you can just enter the final voltage without having to adjust the other values? That would be the simplest and most convenient approach.

no, a weak psu would drop the voltage even more under load. both my dfi nf3-ut and msi k8n neo plat. do this... probably something to do with the efficiency of the PWM circuit with varying load.

Still could be something with the PSU possiblly. I've got a cheap PSU that has the 12v rail go way up under load. Like idle is 12.6v and load is 13v or 13.1v sometimes.

nice table :)

Great work and thanks :) ive been looking for a way of getting 1.73v for AGES but too lazy to work it out myself :rofl:

Thanks :up:

With a multimeter?

great post this is just what i was looking for after wiping out cmos.. thanks for taking the time to make this for us.
