Use PC Health menu to monitor the voltage.
The reading reported by the PC Health menu fully agrees with my Fluke dmm.

The picture says it all.
Have fun :D
pictures quality are very good :toast:
ok so given the mod's what has been achieved ?
if I recall...
about 1.6 volts is the limit on the VFSB before you seriously just blow up the chip?
2 volts for VMCH is about the limit there too?
been along time since I did these mods on a board (last board was the Abit AS8)
Thanks, this will help alot when I get my motherboard up and running. Just one question, where is the best place to ground? Is it ok to connect to a groundpin on the backside atx-connector?
edit: Also, it's kinda hard to find a 40k vr-pot so would it be ok with a 50kOhm one? Or just typo?
Everyday you need a 40k vrpot, a 50k pot will do as well ;) Just a little less fine tunning...Quote:

The best is to water cool the NB.
Another option (given it's no typo) would be to just use 2x 20K potis, connected in series, to give you a total resistance of 40K. ;)Quote:

Anyways, thanks for the answers.
Nice pic's , great mod, but any result's already? what wil be max fsb after the mod's?
Got the infinity here, but will it go 500 like the asus overhere?
i would be happy if he can make it till 475 :D
Err..Quote:

Awesome job stilt, did you allready passed 400fsb?
Tony mentioned a hardmod for the 1333 bootstrap.. i sure want to know more about that one.
So VMCH mod is to raise memory voltage?
And VFSB is to raise NB voltage?
Sorry so for the questions, people use all sorts of different abbrieviations..

vmch is for the northbridge (chipset) not for ddr2
You can pencil mod the nb voltage too, I already have 1.95 going through mine. Sorry I'm a bit new to the terms here.
So what does the Vfsb adjust then?
wheres the droop mods?
seems like no ones posting those anymore for these new boards, but they need it pretty badly...
Stilt your mod pictures are the best, crystal clear :toast:
I used the VFSB mod today, and set to 1.53v, nb is @ 1.95 (pencil mod), still no real progress, will now boot up a 380fsb, with E6600 Stepping 5 @ 1.4v. Even using 1.5 vcore will not allow any more fsb. I think the limit here is that I'm running 1900's in Crossfire and also Raid 0. This cpu is known to hit 3.85.
Has anyone else had good results??
regards
Raja
this board need a new bios with 1333 strap :stick:

http://myweb.tiscali.co.uk/glenweb/pics/3d0612673.jpg
nb is @ 1.95 with air cooling, vtt 1.53. I can set vcore from 1.4 all the way to 1.6, will not post over 380 fsb. Ram timings are manually set, and well within ram speed.
C1E function is disabled (speedstep)
Are there any other options you have disabled/enabled?
What is your nb voltage and temp with watercooling -perhaps that's where the difference lies..
regards
Raja
hiraju the nb is at 1.75 and never goes over 42 degrees, also the other voltage is at 1.35 cpu at 1.275 plus .2125, i have c1e enabled and also have ppm enabled whatever that is in the genie bios settings, i do have my ram at 2.35 volts as well, on a side note dfi have pulled the 0707 bios off the beta bios page now so maybe an update is on the way
dfi have just posted new bios 31/07 for dfi infinity 975 x , i have installed i think only difference is the cpu info and ram info is now correct in posting screen but still stuck 400fsb :( ,
http://us.dfi.com.tw/Support/Downloa...FLAG=B&SITE=US
will post this on a couple of the other threads regarding bios updates
Can someone please show us a vdroop mod for the vcore on this board? It may help with overclocking a little further...
Any news on a vdroop or vcore mod?
Which VCore controller chip does the board use?Quote:

Vmch Is not boing to blow up :D
You just need to use a PCI gfx card beound 1.98 or 2.05 I belive. :)
And DONT boot above 2.05 Just boot at 1.95 and Ajust in windows :)
This is only as I recall it, So maybe not 100 % acurate :p

It reads
primarion
px3538cdsg
cs0155.01
5105 KR
I found where the vcore measure is.

Can't get the full datasheet unfortunately. Primarion only has general information online. :( I can't help you ATM.

Have you tried to email them ?

I just sent a request for the full datasheet. We will see what happens.Quote:

I am a total volt mod noob. Where are the ground points on this mobo or the nearest to the VMCH solder point?Quote:
