Same place as p4p800...Quote:

but... how it works ?
you can try make the wires longer and connect it together after post is complete. :D
(but try this not with running win, memtest86 is saver if crashed or unstable...)
... i mean, the ovp is also "away-modable"... should.. :D
p4c800, i think is like the p4p800, whats the big difference between board to board.. ;)
I made the question cuzz the "normal" vdimm mod on these two boards are the same but in different places on the pcb of the board...
Definitely the same method like the one posted before on the p4p800 pic????
Same place on p4c800?
THKS IN ADVANCE!
Maybe i'm getting confused i dunno but doing that mod on a p4c800 aren't we going to put extra 3,3v on the mem's, i'm saying that cuzz i don't see no one saying that is we need disable the circuit that feeds the mem's on this board...any info on this question would be great...
Thks m8's!
I think I have a theory on the Asus A8V socket 939 OVP. It may also be the chipset voltage that is raised along the vdimm.....!?
Some time ago I modded a Chaintech VNF3-250 and the chipset voltage went from 1.74V to 1.9xV when raising the voltage to vdimm to around 3.24V.....Could that not be a reason for the lock ups in win with more than 3.15V?
Could well be... but i dont remember any other users of the VNF3-250 reporting that same occurence?
Used the PIN4 and PIN8 to mod the vdimm. Well did not see it myself before, only by a coinsident (bad english). Only problem for me now is where to measure chipset voltage on the Asus A8V?
May some of you experts be able to help if I post a closeup of the mobo?
So I only have to solder 1 wire on the back of my motherboard from the points shown in your p4p800 picture, from atx 3.3v to the vdimm point you show? I guess I should remove the "normal" vdimm mod I did in the past. Should I worry about the old vdimm mosfet or just leave it alone? Will the vdimm reading be from the same mosfet as before or do I read it from the socket? I think I may do this tomorrow.
I think u'll only get the VIO voltage, In my K8NPRO it's like that, only the VIO voltage feeds the mems.Quote:

hey VoRtAn_MaDgE, can you post an pic with the interesting area ? ;)
TyphooN, you want mod a p4p800 ?
only connect like the pic, thats all.
no removing... dimm-mod too..., the measuring-point you used is the same as bevor.
the fat red wire is needed, the longer smaller one is not needed, but helps a little little bit.
conclusion: only two solder points. :D
... of what ???Quote:

Alright, that just makes it easier for me(not removing the old mod). So basically the vdimm will be the same or slightly lower as 3.3v correct? I won't need near as high a rail as I am using now(3.62 to keep 3.3 stable).
if your 3,3v actually 3,62v so the vdimm come close to 3,62v and 3,60v under mem-load, memtest86 #5
the success is depending of thikness of wire. use a fat as possible (massive wire).
Alright, I think I have some thick wires, from an old psu. Thanks for your help =]
I did this mod last night. It works awsome. I just wish I could turn down my 3.3v some more, the lowest I can get it to is 3.5, and I do not need that much vdimm for how fast I am running it. I hope it isn't bad for the ram.
BH-5 will take it with ease as long as you have some kind of fan blowing at them.
Crank up the fsb :D
I have thermaltake copper ramsinks on them, I don't see how I can have a fan blowing on them. I can't really push the crap out of my ram right now till I get a 3.0c or a 3.2c, but when I do I'll rape my ram lol.
hi,
here the mod for AOpen i855GMEm-LFS.
simply again, like the old scheme... sold the red wire to the points.. thats all.
vtt raising automatically. :)

Does the 3.3v mod work on a DFI Infinity?
I think the Infinity draws its vdimm from the 5v rail doesnt ? So doing this mod then increasing the 3.3v rail wont make any difference right?
Nope, just vmod with a resistor...
I have a few questions.
How are you guys gettings 3.6 and above with your psu's, I have an antec with the pots that I can adjust but I can't get more that 3.33.
I did the mod on my MSI neo 2 and it works awesome...but I need more voltage, I am stuck at 250 fsb right now with 2,2,2,5 1:1 timings.
Did we ever figure out how to use the 5 volt rail? because my bh-5 is screaming for some 3.6+ volts
Thanks
Bryan
I think people have avoided doing the +5 for vmem on the boards because people have been saying high +3.3 or high vdimm kills A64.
The shuttle an5x used +5 for vdimm and i'm sure there are a couple others that do too which havent killed any cpu's yet without a vdimm mod... so somethings not quite right here. If I had a board and CPU to potentially blow up i'd glady test the +5v to vdimm mosfet on the LP-UT (requires cut trace) to see if it works.
When you do this mod, you are completely bypassing the motherboard circuits that provide the vdimm, making them irrelevant.Quote:

I modded my 4PCA3+ tonight and am at 285 FSB and climbing... :toast:
Man if I knew it was that easy would have dont it along time ago!
I need to do the PSU mod now to get my vdim above 3.26.... :cool:
I don't mean that this mod is a good idea on all boards, I mean that this mod will supply 3.3v directly to the ram on all boards.Quote:
