Anyone have a link to these mods yet? I need more vcore for sure and I think 2v vdd or even 2.1v vdd might help a little also. I can't seem to find anything anywhere yet except for the vmem mod of Holts in the mod forum.

I don´t think you need vdd mod for this board i can do 272 fsb easy with 1.7-1.8 vdd...i dont think you need more than 1.9 v(if you dont want to run @ 280-> fsb)Quote:

You might be right there. I can't seem to get 240x10 stable since my cpu needs 2.1v for 2400mhz and I can't get anything over 250fsb prime stable either. I'm running prime at 9.5x 250 now with the 12/31 bios. My ch5 sticks either seem to be giving out or It's the vdd. My sticks won't run at 3.3v either. 3.2v is the max they will run . At 3.3 they error out almost instantly.
check page 16 of the dfi rev b thread for teh vcore and vdimm mods.
There is only a vdimm mod on that page. No vdd or vcore mod.
vcore is this:
Vcore reg is near the mosfets, on the agp slot and it's labelled HIP6301. Mod is pin7 to ground with 50k pot.
that's the one.:)Quote:

Thanks. Any pics?
Anobody seen SAE, he was about to try the vcore mod a couple of days ago.
I would like the hear the outcome of that, because i havn't seen anyone mentioning the OVP. And I seem to suffer from the same OVP issue as i did with my 8rda+. I can use 1,95 totaly fine, but as soon as I set it to 2,0 I get random reboots. Just like i did with the epox.
I would definatly like to get some more vcore, since I'm atm is vcore limited.
i did the volt mods (vcore and vsense)
Pomona grabber to 47kpot, then to ground. Grabber ends modded slightly so they clip and hold without touching the legs on either side.
you NEED to do the Vsense, or the board will crap on the overvolt at 2.1 and beyond.
enjoy, it was a piece of cake. this is the DFI, not the NF7, and it is on the test bench running 10x241 with stock AMD cooling, oh my.
b
still need to do the moffsets,
an old swiftech MC370 on the northbridge, swingout fan for the memory, thermaltake blue orb on the southbridge. notice the stock AMD unit for cooling, made the volt runs kinda hard because of the temps, but i got her almost ready to put in the Prommie.
BTW, the Southbridge did more for stability than the Northbridge. in fact, you could prbably just use the stock heatsink with a fan added and it would work about the same. overkill is on my menu, always, ya never know.

Could you perhaps make a small tutorial with pictures on how to do the vcore, vsense, and mosfet mod? :)
but, except for the pomona's, it is posted somewhere here on the forums already, how do you think I found out about it.;)
baldy
Cooling the 6 MOSFET's near the CPU immediately gained me 5 MHz stable FSB.
what did you use to cool them johnson
Heh - I have a bag of about 100 4-fin 'lil heatsinks I got through a link here at xtreme. Where is that link??? Can't find it. Like $0.25 per sink. Agggh!
i get mine at amdmb.com for $.55 each.

What pin is the Vsense mod,to ground?Quote:

i think those of us with the week 24 chipsets can utilize the extra Vdd. If youve got a newer chipset (your socket will have a plastic arm instead of a metal one) than you dont need more vdd. On newer rev chipsets, they dont need extra vdd to fly, but just like old nf7's, if youve got an older rev of the chipset, the vDD will certainly help
yes it will. i beleave the vdd mod is a 5k ohm pot from pin 3 of the tiny IC with 8legs under the agp slot.
same chip as the AN7 uses.
I think so, and pin6 should be the vagp mod.Quote:

How did you get the HSF on your SB? just used the adhesive and it worked?Quote:

What is the Vsense mod? I know vcore is pin7 to ground with 50k VR on HIP6301 chip. But the dude up there said you needed to do the Vsense, so how do you do that one? Thanks.
you only need that to overcome the ovp when going over 2.1v
Exactly, so how do you do it?
If anyone could just tell me the vsense mod...that'd be great. Please, thanks.
vsense (VSEN) is PIN 10 on the same chip (HIP6301). So instead to solder only -> : PIN 7->50 Kohm trimmer-> ground : , you repeat the process another time -> : PIN 10->50 Kohm trimmer-> ground :
. So you must to do 2 complete mods for the vcore. :) Check this also. http://forums.extremeoverclocking.co...c/21990-1.html ""If you are using an AMD rig and are going super high and the system cuts off on you, you will need to start lowering the resistance of the other resistor (@VSENSE ) to "fool" the over voltage protection. You will just have to fiddle with it since it's not an exact science. "" ;)
:cool:
Thanks a lot man, best explaination I could have asked for. :)
Happy to helped you. ;)
Erm... Vcore mod allowed me to use up to 2,25V w/out doing any ovp mod
:idea: Maybe I was lucky.
But now waiting for an rma. Hope I get a good board this time :)
P.S. Vdimm at 3,55V and Vcore at 2,17V never caused it to act as unstable as the nf7 did. Was able to bench and do other things in windows.
At least that's positive.
well i did the vdimm mod.. i did it righ this time.. no removed resistor! w00t!
it looks great.. i might test the board tonight and see what i can do with 3.7 vdimm. im gunna try to give viking a ruin for his money. i know my ram did 260 benchable at 3.3v before so i think 3.7v should give me just a little more ;)
(no this is not a suicide run,,, yet, that will be 3.9-4v:rolleyes: )
You must have been lucky SAE... ;)
And good job spork, good luck to you...and your ram. :P
Unfortunally the Vcore mod didn't work for me. I did it with the Vsense also but I only managed to get blue screens...
bummer.
I still have no clue how to do this. =\ I wana get over it so I can try for over 3ghz.

POMONA SMD grabber, hehe

People prefer Pots and VRs(Variable Resistors).Quote:

Also, there is no soldering required in this mod, correct?
I prefer Fixed resistors.
Yes you still need to solder.. Soldering will come to you one way or the other, sorry.
arg. if i was on my comp i would post pics of an smd grabber tip and in my hand. ohwell. they work well, use them on my epox.
you have to solder the wire to the grabber itself, its alot bigger and easier than the actual IC leg to solder.
any dummy with a soldering iron and half a brain cell can attach the wire to teh grabber.
No. You ll need one for each mod to attach to the chip's legs, these wires you solder to the pots. then you ll need wires to ground them... soldered to the pots too. You can put them under a mobo screw... that was it.Quote:

So, I need one Pomona Grabber for each mod (vcore and vsense) and I need one pot for each also?
oh. misunderstanding here... :D
I thought you asked if you should buy two additional grabbers fpr the pots and not the pots themselves ;)
My fault.
Rat shack should have what you need. Of course, now all they are interested in is selling cell phones but you might get lucky and find some locally rather than ordering online. My local shack has a few pots left last time I went but their stock is getting really low. Chances are though as soon as you attach the mod you will have instant instability. Only a few people have been able to run a voltage mod without making the board totally unstable. See my other post I started about the issue.
I'm ready to do the vcore and vsense mod on my DFI LanpartyB mobo. What's this in the above post about it making the mobo unstable?
What resistance do I set the 50k trimmers to on these mods? In other words, what do I set the 50k trimmer to using a multimeter BEFORE I install the mod? Any help much appreciated. Thanks;)
Well.....damn....thanks for the link. It looks like the Vmods are on hold until someone figures this out.
I could have had this mobo up and running days ago. I waited until I got some more trimmers off Ebay delivered as all I had were 10Ks.
Guess I will add the North bridge cooler, heatsinks on PLL, Mosfetts and chips and stick it in the MachII to see what it does stock. :(
PLL==Phase Lock Loop - it's the chip responsible for generating the clock signals, like FSB, PCI and AGP (among other) bus clock signals.
yeah where is this PPL?!
i would think that lil chip would be a smoker.
It certainly is, infact it is referred to as the "overclocking chip". It's about as wide as a mosfet, but atleast twice as long. Generally they are located near the CPU socket.

im getting ready to do Vdimm and Vcore, but i need to know where to get a read for Vcore. i tried to read it from pin7 on the HIP6301 chip, and thoguht i had it when my multimeter read 1.87 (set at 1.90) but it says that for 1.85 too, and at 1.95 it reads 1.80, and 2.0 reads 1.85. :confused:
btw, i didnt know the onboard voltages sensors were such crap. they always told me my DIMM was 3.20 or 3.24 but its actually 3.34 with the multimeter. perfectly stable too, even under load. i really do need to get a read on the Vcore though, so if anyone can let me know, id be glad.
no one?
