IS7 Vmem mod?

**bito** · 07-02-2003, 07:41 AM

I know the mod. is the same as the IC7, but instead of R50, is it R567 i need to remove ??

I did the mod for a friend a few days ago....cant exactly remember the name of the resistor, but its in the same location as the r50; the top resistor to the right of the winbond chip.

HTH.

yes pls...post here or mail it to me.
Thanks

Well Pc ice ive done exaktly what u done,and i dont get it....I only get aprox 1.44v on this legs u showing...

**gabbax** · 07-21-2003, 01:17 AM

ok

**gabbax** · 07-21-2003, 01:30 AM

hmm,when u atached the vire to the "thing on the board,did u ONLY atached ONE vir? "vire on the "THING" and then to ground? il atached on the other side too....schould i atached that one directly to ground? insted...

**gabbax** · 07-21-2003, 01:40 AM

Hmmm, now il get it

u simply removed the Exicting diod and replaced with wire to the 350Ohms VR am i right...

**gabbax** · 07-21-2003, 01:47 AM

Man do i feel like looser or what

is it hard to remove it? just atached the "hot.pen" and grab it witha pincett? den put the cables on it

**gabbax** · 07-21-2003, 01:58 AM

Ahhh,thx man just remove it totaly...(Boring,iv just put my things together now)

.Il do this after lunch il put my 2kOhm VR to 350 and then

**gabbax** · 07-21-2003, 03:25 AM

Hmm well it didnt change annything for me

It is my processor who stops me to get anny further

.Well i hav a verry good Modd thx to PC ICE

man il sit down later and do some testings

**gabbax** · 07-21-2003, 06:59 AM

HEhe,well i can now run 285x12 Ratio:5:4 timings 2.5-7-3-3

**Ragnarok** · 07-23-2003, 04:43 AM

cheers, did the mod and it worked

though it was bit scary to remove the lil surface mount component (it's so damn small)

**Creative** · 07-23-2003, 07:32 AM

Yep the mod was done 100% successfull and im currently getting 2.78vdimm when set to 2.5 in bios and 3.15vdimm when set to 2.8 in bios.

We started at 300 ohms and then worked up and i think it was ~450 ohms when we settled for the above settings

VTT has dropped to 1.24 volts when vdimm is set to 2.90 (real) or below....but when it gets up to ~3.10vdimm (real) it rises to ~1.36

So it looks like the are related somehow.....

Kudos and many thanks to Ragnorok and his cousin for doing the mod for me while I looked on

Hi guys, where can i find the IC7 mod so I can do it on My IS7, I´m dont know xxxitz abou soldering, so I need an good guide that I can show it to a friend of mine, who by the way nowz xitzzz about computers

**Netto** · 07-30-2003, 12:44 PM

Huuu sorry heheh read it wrong,

What I need to buy:

Is it possible for you to take a Pic, of the entire mod, With the 1K VR, because I need to go buy one, and I don´t know the translation in portugue for a 1K VR, I need to see the little sucker

**Ragnarok** · 07-31-2003, 06:04 AM

1K ohm variável resistor (at least according to babelfish)

http://members.iinet.net.au/~zzhang/nf7smod.jpg

different board, but u can see a variable resistor next to the AGP slot

**Netto** · 07-31-2003, 06:23 AM

I would like to use a resistor like this pic, 330Ohms, can give me 3.1v? Or I need a Higher rated resistor?:

if I use de 1K OHM Variable Resistor Do i need to ground it?: Because I saw it has 3 legs, so I´m not quite sure where do solder de cables
I really preffer the resistor mod over the VR,

**Ragnarok** · 07-31-2003, 06:45 AM

u can use a fixed value resistor, prob need a 400 ohm to give u 3.1V

btw, one of the 2 soldering point is a ground...

Tks man, gonna look for some 400ohm resistors to do the mod, since I´ll be taking the mobo of the case, Ill put some cooling in the mosfets and put a zalman heatsink on NB

Thanks for the input, really helpfull

**Netto** · 07-31-2003, 07:11 AM

One last dought, if I use a resistor, do I have to ground it?: The Vr needs it?

**Ragnarok** · 07-31-2003, 07:07 PM

1 of the 2 soldering pads is a ground.....

**gingeralenz** · 07-31-2003, 09:28 PM

let us know how u get on and post what is your max voltage when using the 400ohm resistor.

**Netto** · 08-15-2003, 07:30 AM

Ive used a Trimpot, Can go all tha way uo to 3.2Vdimm, heres a pic
