A7N8X SB/NB mod

[Teus]

I'd like to see a few things cleared up. what's the difference between the following mods?

and

a) does the first mod only raise the voltage of the NB?
b) is the second mod the best (though hardest) way to raise the voltage of both the NB and SB voltage?

I can't do the effort to scroll through all the threads, that would cost me hours of work. anybody here can clear things up? :shrug:

The first link you posted is the best way to do the mod in my opinion m8.

To be honest, I am not sure as whether or not the vdd mod will increase both NB and SB voltage or not. The important voltage increases are felt in the NB chipset however as increased voltage here will most likely (but not always) yield a higher stable fsb.

If you do the mod, you will need better cooling than the stock heatsink in my opinion. If you decide to use the stock, then add a 40mm fan above it and take off teh NB hs and scrap the crap from the factory off and apply a better paste.

The reason I dont think any added voltage to the SB helps is because the SB runs things like USB, Sound, etc etc.

These pins are very small my friend, so ya better have good soldering skills or use smd grabbers or ya could kill the board.

I would love to find a southbridge Vdd mod for NF7-S, it seems that's the only thing holding me from 242+ Mhz

thanks hellfire for the info. I don't think I'll do the second mod because it's explained poorly +I don't think the SB mod is really important. I've bought an Asus board because I've heard they're very reliable and stable. I'm not aiming for the highest FSB's, I just have the most fun when I'm modding my board and keep finding stuff to cool it better :)

the NB will be watercooled and I'll put heatsinks everywhere

that's why I bought this board: get a recent board with more tweaking features, a faster chipset with more possibilities and a higher FSB then my KR7A-R. who cares about that thousend more 3dMarks I achieve, as long as I've got a nice and stable rig I can keep messing/tweaking/modding with for weeks/months :toast:

Then you will like your A7N8X my friend.

I have enjoyed modding it and squeezing it to death..lol.

Mine has been a rock so far, unless I push it a little to hard obviously. But no stability issues under normal use and up to 215 fsb.

My 2500+ will do close to 2.6GHz on air, so I like the setup for what it is.

thanks :thumbsup:

Calantak sent the board in RMA, so I'm still waiting until he gets it back from germany... We're already waiting 11 days!

The difference between the mod is that the nForcers way pin 7 is used en the MaximumOc way pin 11. The difference between the mods is described @ nForcersHQ. I think both mods are raising the NB as well as the SB, since the modifications are done on the same IC. The mod is called the southbridge mod, because the location to solder is near the southbridge.

The reason why you could mod on pin 7 (nForcers way) best is because when you are using pin 11 the wire you're soldering also functions like an antenna.

All this is discribed at nForcersHQ in the thread mentioned in the start post.

I have done the mod the nForcers way, and it's working perfect for me. I'm able to run 240 x 9.5 (10 and 10.5 multies aren't working)

thanks. but I'll do the pin11 mod I think, the pin7 mod is explained poorly and it's much more work

Regardless of which way you go with your vmod on the NB/SB...I definitely wouldn't use the method where you are "not" soldering to the IC but to that little uber tiny block.

But, those danged pins on the IC are uber tiny in their own right. Can ya say "SMD Grabber" boys and girls?
