Well no prgress on my part, didn't get the bypass mod to work :-/
I have tried to pencil R316 (lower resistance) to get lower DimmVoltage, but it doesn't work at all. Maybe it will work with removing this resistor and change it with higher one.Quote:

O/T
I found the VDIMM mod for this board:

Hell-Fire, can you confirm this? The guy says to remove resistor R316 and replace with a 1K VR set to 0 and increase for more voltage. Does the resistor have to be removed? Why not just solder the VR directly to the resistor? Also, does this board need the VTT mod like the NF7? Can someone post a pic w/ all the voltage measuring points for this board?
Dont be scared to remove it. You just have to heat it up a little, and take a plier to take it off during that you have the solder the end....
:rolleyes: :) :DQuote:
extrem is it ...
You coudl take the pad with it pretty easy doing it that way, just heat up one end and push the iiron towards the SMD resistor, it will start to lift, do this for both sides and it will pop off.Quote:

Some1 should try vtt, it should be pretty easy for this board, it will probably work similar to the mod on the abit A64 boards because it uses the same vreg, ill post more info later, if some1 could get a pic of the DIMM slots and above the dimm slots (top right of board) that would help out alot.

Sry for the double post in advance but i dont want to confuse ppl :P
Will somebody set vdimm to 2.8V and check the voltage on pin 7 of that winbond monitoring IC. It should be Vtt sense, just want to confirm it, and if i get a pic of the top right corner of the board we will have vtt :D

[EDIT] What do you guys think about this for the Vdd mod?

Why set to 2.8V? Where is that pin 7 on Winbond monitoring? I will measure that voltage...Quote:

Have you tried out that mod you showed us?? :D
No i dont have an AN7. :D
oh and u dont have to GND to that LM358, in fact a better ground would probably be easier and better.

Do you mean that Winbond monitoring chip that sits between CPU-Socket and memory slots? I will measure voltages, but must know more about your plan. I can't measure without any info... ;)Quote:

Pin 7 on this IC, and probe all the other pins too if u can :D

Measuring voltage of that winbond chip is impossible! It is to small... Sorry there is nothing to do for my part. :mad:

That's my board!!!!!
Hhehhhhheheh....
That's mod is usefull, but is good for stable voltages, but you can't rise Vdd....
This is my thread on an italian forum...

I have experience some Vdrop on Vcore at high frequency and this mod can stabilize it!
Cya and if you need information for capacitor ask me!
Can anyone measure the voltage i mark with blue color ;)
So if I do a Vdimm-mod on the AN7 3.3 V is the highest I will get?
Ridex that chip is not that small, all i need is pin 7 please try just clip ur black DMM lead to ur case and rest the red lead on pin 7, then boot up the comp and after u get a voltage (doesnt have to be exact but close) take the red lead off and youll be fine! :D I really need some1 to measure those voltages :/

Sorry, don't have anything to measure with right now, a friend has my multimeter...Quote:

CaTalyst.X: The Multimeter of my brother is really to big to get one small pin, sorry.
The following measurment i have done:

Well erm, my AN7 is running at 240FSB with CH-5, need more juice to get 250MHz as im at 3.2v already on the vDimm...however I found out something fairly interesting regarding vDimm volt modding today, the vDimm runs from the 3.3v rail on most motherboard, and this usually means the board will max out at about 3.2v naturally and will have problems going any higher, so would it not be easier modding the board to use the 5v rails rather than the 3.3v rail with some form of potentiometer in place to keep the board safe...I think this is something like what the OCZ memory booster does...worth a shot though
You could solder the +5V line straight to the source of the Mosfet, but thers no guarantees it wouldnt shoot 5V into ur PLL or SB. (not good)
-CaT
No but if you were to do a mod like that guy with the ASUS pentium board (cant remember the model) where he made the vDimm run off of a seperate 5v rail so ONLY the RAM got the 5v, he also then went on and chopped up an old motherboard and used it as a regulated power supply for the RAM or something. I know you've seen it Cat.X because you were posting in the thread the guy made (not sure of the forum though)
Would that not be possible here?
Has anyone had any luck with the chipset volt mod yet?
HEY MAN!!!
I can say to you all that you want about voltages on An7....
I really intersting about Vchipset Mod....
I hope that someone can help me to find the VDD MOD...
Cya!
Sorry for the failure of not showing any pictures. There was a harddisk crash on server. I don't know when it will be fixed. If you want this pictures to be shown here, then i can pm it to anyone who wants to host it.
