Can some one post vmod pictures for the DFI LANPARTY DK P45-T2RS. This babe will be at my home next weekend, so I need some vmod pics, if some one have it. Thanks in advance!
Any one please? I take picture for the mod :) so if any one can help please do it. For me vdrop mod is most important. :)
Thanks in advance mates. :up:

thx hiwa, I have been looking for this
Thanks mate ;)
awesome thank you
Another way, better if you have an economic soldering iron :D
Same trimmer as Zilla's said...for me work with less than 50k...around 30k for +0.150v

IMO, this "alternative" point marked on that Zilla's picture doesn't work, because it's not connected to FB pin!
My suggestions:

For Vcore mod, connect 200kohm or 100kohm VR between FB and GND.
For Vdroop mod, connect 50kohm or 20kohm VR between FB and VDIFF.
I'll do the mods ASAP and report back.
I hope it does, just had mine done on that spot :DQuote:

I don't know...in my mobo work well...
Good to hear mate, wil check mine out this weekend.
It most likely works because it seems there is just one resistor between the real direct connection to FB and the solder pad that circuitburner suggested. The resistor will probably just act as a limit for the max voltage. Which means it's probably not even bad, as it'll be harder to kill something by setting the resistance too low, i.e. the voltage too high. But as I don't know the value of the resistor (and even if it really is a resistor), I can only guess here.
celemine1Gig, You are probably right :)
I'll measure the resistance tomorrow and report back.
It measure 2.21kohm :)
It's a resistance, so i think you can skip it with the trimmer...for me was difficult to solder in the original point
Yes, that little resistor is ~2,22kohm, so the final resistance to GND is ~45,3kohm. But the spots on FB trace are good enough to solder ;)
AND the 2.22K resistor doesn't help much, as to preventing overvoltage, as a fixed resistance, like I wrote about in my other posting. ;) That means it's no real argument for or against using either point to solder to.Quote:

But that's just how I would do it, after accidently killing a i955x chipset through an opamps hiccup mode. :rolleyes:
Friend of mine wanted to do Vmods for that T2RS Plus. But due to his low experience, he managed to crap the board :mad:
http://ceemic.pri.ee/hardware/t2rs_p...apped/dfi2.jpg
He broke one ceramic-cap on one end (luckily the pin had still contact and it works) and one extreme little cap came off. It's approx. 0,75x1,50mm :shakes:
Also he broke FB trace, so I had to solder a wire directly to IC.
I somehow managed to solder the cap back and I did Vcore and Vdroop mods also :p:
http://ceemic.pri.ee/hardware/t2rs_p.../dfi_mod01.jpg
I used 100k VR for Vcore and 10k VR for Vdroop.
All works :)
Hehe nice save! :up:Quote:

nullface, what? Vcore and Vdroop mods? It depends on IC and layout. Even if the IC is the same (ISL6322 this case) then default resistances may vary due to different layout.
Do a macro-pic from that area and lets see ;)
Does this mod apply to LP DK P35-T2RS too?? Both use same controller, ISL 6322.
Thanks
gondezz, yes, but You have to check the def resistances.
