Asus nFORCE2 A7N8X mem/cpu volt mod

Mega thanks to DDTUNG for this... obviously couldn't have done it w/o ya :) You own!

This is for the CPU. Connect to this pin and ground. This chip is between the cpu socket and the back ports.

This is for MEM. Connect to this pin and ground. This chip is on the top right of the mobo.

Thanks for taking the time and sharing to help everyone...

Could you recomend a fixed resister value... for each.... To get like 2.0vCore, and 3.0vMem?

I don't like using the VR's .... They can drift, or get moved.... Besides I'm aircooled so I can only go so high....

thanks, Royd

Erm, I dunno hehe -- I don't think I can check resistances while it's soldered on can I?

Could you make a photo of where to check the vmem.

No, You can't .... I guess I could play it safe... and start on the high side..

Wow I totally forgot, but then again I remembered... here ya go:

I'm a noob when it comes to vmods so please excuse my ignorance. What is a VR? Also, when you say "ground" do you mean, connect the other end to the chassis?

Thanks sys.

THT,

A VR is a Variable Resister... Or Pot... You can get them at Radio Shack... With the recommened Resistance.

And Yes, Ground is the Chassis.... I like using the Bare Metal Surface around the Holes for screwing the motherboard to the case. pick one closest to the VR....

BTW, Sys, Nice picture...

Royd

Excuse my daftness but does increasing or decreasing the resistor value give you more voltage?

I'd rather not try this the experimental way;)

Decrease resistance of VR => Voltages go up :)

So by doing this vmod, will the BIOS have more voltage options open or will the board just overvolt the CPU?

Thanks! :) I use the fan plug grounds myself. ;)

Well you can turn the VR to whatever voltage you want on the fly. It doesn't actually give you more options in the bios like "2.00" and you can just select it in the menu. What I do is I have set the "1.65" in the bios to 1.95. So When I put it @ 1.85 I get 2.15. Then If I want more voltage I'll just up it w/ the VR while in windows.

hey can sys can you link me to the data sheet for the Vmem regulator i cant find it

i found the one for the Vcore http://us.st.com/stonline/books/pdf/docs/8162.pdf

Nope I can't. DDTUNG can though ;) He found them somewhere... I tried looking but had no clue where to find em.

Sysfailur, do you have the whole code of your Vmem voltge regulator chip?

Must I checked is when the computer s on??
The red is to check the voltage right?? and where must I put the black of the multimeter??

I am a noob:)

sweet Sys, your the daddeh :D

The computer must be on, yes. Then take the red lead from the multimeter and put it on the pin, and the black lead on any ground in your computer ;) And you should put your multimeter on V (V for voltage) and on a scale of 20. If you set to 2 it won't work cus the voltage is over 2. ;)

sysfailur, first I must thank you for your great work :)

I did what you said but I dont get a voltage in bij multimeter
It only says 0.00V
Can I measure the voltage without doing the Vddr mod?? I didnt do the mod yet. But I think you can measure the Vddr without doing the mod. You will get the Vddr whats in the bios right??

You're welcome! You may want to check your mult, you may have it on the wrong V. There are two and you need it on the other ;) Or, just recheck to make sure you're connecting properly. You don't need the mod to be able to see the voltages ;)
