ASUS A8R MVP Voltage Mod Shamino Jan 20th, 06, 09:32 AM #1

The ASUS A8R MVP is a great performing board with very high HTT overclocking capability. However, it is somewhat limited by its voltage options offered in its BIOS. For those who are looking for higher voltages on this board, we have the answer for you...

Excellent, I've had my eyes on that board.
My idea was to undervolt it and then use it as a HTPC, an undervolted Opteron vill run very cool I think.

Could one cut that connection completely and solder a higher valued resistor there for hitting those lower volts...like 1.0 - 1.1 volt?

Just what the doctor ordered...any chance of a chipset vmod? The board suffers as much from this as vcore.

In theory, yes.

Kudos for the mod.

Is your HTT bottlenecked?

its more of a ram issue as said in revierw
with a pair of uccc no 1T for me.
tccd is 1T GG. Results may differ but hopefully it's just a memory compaitiblity issue that can be solved through a new bios.

Hey guys,

I did the volt mod & it is working very well. I'm at 255x11 = 2805 mhz @ 1.6 volts & running well.
I posted pics of what I did on this forum below. Feel free to check it out & ask questions if you wish.

At the top of this page is my rig I designed & built. Scroll down for volt mod pics.

Any chance someone could figure out a Vdimm mod for this board? I already have the Vcore mod done to it, but my BH-5 needs the volts .

This is turning out to be a pretty nice board, very stable and has my Sandy at 3157 mhz so far.

I heard that u can solder at pin 7 at Ram slot to bring the vdimm to 3.2volt. As of how to do it, I have not idea. May be u can ask the expert here. I did not try any soldering at all to my ram slot before. Thus u better get the confirmation first before doing it.

A "Kyosen" mod for this board would be great as well. I have a OCZ Powerstream so I can pull up whatever I want on my 3.3v line.

I can take some detailed photo's of this board if any of the experts here need them...

A few ways about it. you can do a solder from a pin at the back of a capacitor to the 3.3v atx pin behind or a solder from a pin behind the dimm slots to the atx pin. i think the pin from back of cap should be easier so let u know when i get around to it
