+3.3 = vdimm mod #2

[STEvil]

Step 1: Identify VDIMM mosfet
Step 2: Identify output leg by adjusting VDIMM
Step 3: Solder wire from input (usually backside or middle leg) to output leg.

DONE

Does this work better than 3.3 = VDIMM? I dont know since I dont have a board to sacrifice in testing atm, but i'll test once i've got time if someone doesnt beat me to it..

:D


CAUTION: MAKE SURE YOUR VDIMM MOSFET IS POWERED BY THE +3.3 RAIL SO AS TO NOT SEND +5v THROUGH YOUR RAM!!!!!

Disclaimer: I'm not forcing you to do this :D

Compatability: Any board that uses +3.3 for VDIMM supply should work unless the board also has OVP (though this may bypass that on some boards).

This is a very interesting idea STE.

From now on, you must give me all your good ideas, so I can use them as my own. :hehe:

Who is gonna step up and try this?

[STEvil]

I already do lol!! :D

[blinky]

good idea, it doesnt freak out when u bypass the mosfet??

[GomerPyle]

STEvil do you have any pictures?

Would like to try this on a Asus A8V...But not sure about how, could you help if you got some closeup pictures?

[zillaoc]

so are you runing a 10k pot between your 3.3 v atx header line direct to your output leg on the mosfet???

[STEvil]

Blinky - Depends on the board, but this is basically the same as the original 3.3 = vdimm mod..

GomerPyle - I havent even tried the mod on a board yet.. none of mine use the 3.3 rail for vdimm supply.

Zilloac - Where does a 10k pot come into the equation?

:)
this mod should work too...

1)
but the "high" resistance of tracers are still there and dropping vdimm a bit.
hipro5's mod cleared this.

2)
on some boards, the dimm-vrm is as multistage circuit designed.

[xtremetheme]

Well im no expert on this, but arent you bypassing alot of caps and circuits from the normal way to the dimms that should filter spikes or such. Or is the 3.3V that comes directly from the PSU "clear" enough to be fed directly?

All this wire soldering on the same FET. You gonna get a fried mobo.

[STEvil]

my geforce 256 is still going fine.. 3.38v core and 4.0v ram ;)

Did what I described here to it just for kicks.

[Malves]

Kewl! I hope I am wrong.:)

[STEvil]

Well, been that his is the same as the original +3.3 = vdimm mod except for attachment locations.. yeah.

[STEvil]

bump - i'll have my Shuttle AN35N back for testing in a couple weeks or so hopefully... ;)
