Help with vdimm & vcore mods for ASUS M2N-SLI Deluxe, please.

Hey guys!

I would love some help figuring out vdimm & vcore mods and reading points for this board, ASUS M2N-SLI Deluxe (nForce570 SLI, Socket AM2). I know that Shamino already did those for M2N32-SLI Deluxe (nForce590 SLI) but it doesn't seem to be the same :(

I have taken few shots of maiboard in question below. Max voltages at this moment are 2.5vdimm (BIOS) and ~1.65vcore (BIOS). I could use some vdimm of 2.7v+ :D

Thanks :toast:

Can you check the voltages at the 2 points I've marked please

holy jesus.

look at how close that cap is to the PCI-E lock ? are these morons really that fvk'n stupid holy crap.

i thought it was bad on my -e premium board
man no way..

Both points shows vdimm voltage in my M2N-E that has the same layout than M2N SLI. In mine it's 1,96 on the IC and 1,95volts in the inductance...

Any news ?

Can someone check the resistance between the pin I've marked and ground please.

There are 512ohms. ( with power off of course )

Thanks!

For the Vdimm mod, connect a 20k VR between that pin and ground. Decrease resistance to increase voltage.

Thank you very much, ill try it this afternoon or on friday, as soon as i can. :)

For the Vcore mod, can you check the resistance between the pin I've marked and ground please.

is it important how much W (or maybe current) can handle 20k VR? Or i can use any 20k VR that i can find?

max voltages in the BIOS are 2.5vdimm and 1.65vcore right? (like M2N-SLI Deluxe)

No, you can use any vr you can find. I use 20-25 turns VR. The vmod just manages voltages, not current ( this remains in to the mosfets i think ), so wattage isnt important.

Stock on my M2N-E is just crap. I can just adjust vdimm up to 1,95v and vcore up to 1,62-1,65. If i were able to get 2,5volts to de ram i wouldn do the vmod, yet. :D Anyway maybe something's wrong with my mobo or so that i can just adjust that voltages, i thought id have the same than m2n sli since they use the same pcb... I'd like to know if we can use m2n-sli bios, but i dont know anyone who can say something about that... :(

Regards!

Sorry persivore, late to the party but I will give you answers from my M2N-SLI Dx. BTW, thanks for help ^don.k's^ :)

Now, to the answers:

post #2 --> both are 2.52v (at 2.5vdimm set in BIOS)
post #5 --> 512ohm
post #9 --> 1530ohm

BTW, vcore can be measured at that choke's leg, on the last pic of my initial post. At 1.537v set in BIOS, I get 1.57v from DMM and also 1.57v from BIOS Hardware Monitor.

I will try vdimm mod next week, persivore! Thanks for that one :)

EDIT: I have just added a legend for vcore and vdimm measurements on this mobo.

http://www.clockmehigh.com/cooler/sc...ringpoints.jpg

Just did vdimm mod, and it just works perfect, i went up to 3,12v ( yeah, i was really scared when i saw it @multimeter lol ), and got this with my better pair of 8000UL:

http://img340.imageshack.us/img340/9818/5661av.th.jpg

Using 2,8volts.

Ill post pics tomorrow, as i thought, M2N-E and SLI are the same, in pcb and vmods too.

Regards! :toast:

^don.k's^ do u have same cold boot, and reset problems like bachus_anonym with his m2n-sli?

p.s. 3.xx vdimm for ddr2, uf wau :).

Yes, i cant reboot from windows without shuting down, and saving bios needs some restart, this mobo runs great once you get it running, but, it's hard to get it running lol

I'll keep testing with vdimm mod this afternoon when i get some free time, i'd like to hit 580 4-3-3 :p:

Regards!

For the Vcore mod, connect a 50k VR between the pin marked in post #9 and ground. Decrease resistance to increase voltage.
If the pin on the chip is too small to solder to, could someone post a high res picture of the chip so I can look for an alternative solder point.

Cool! Thanks! But you're right, those legs are quite tiny. Here's a close-up I managed to snap, without removing a heatsink. Kind of crappy due to bursting flash, but only this way I could get the traces to show up on a pic.

:toast:

EDIT: It looks like that soldering pad I marked might be the best choice for an alternative for Pin7, am I correct?

Tomorrow i'll be in the work, i hope i can find an alternative point for #8 pin. Also ill do pics of my mod, and more tests :D Ill keep this updated :)

Regards! :toast:

Im here again :p:

Vcore mod:

THIS DOESNT SEEM TO WORK! I HAVENT TESTED MYSELF! Sorry( just vcore mod )

This board is maybe the best one for AM2 when moded, layout is perfect, memory goes in 1&3, in other mobos is 1&2 (Abit, Epox..... not so good for cooling the memory), cooling of SouthBridge is perfect, location of sata, ide, flopy, power is perfect, the colour of board is beautiful, everything is perfect :). Damn DFI what are u waitnig for..... until Asus rocks, can't wait to get one, i can't get it it in my country jet. I hope that new BIOS will resolve cold boot and reset problems, and maybe some extra oc features or higher HTT. :toast:

Yes, once moded, i love this board :D Would be nice more voltage regulation but for the cheap it is, isnt bad at all...

Can anyone comment the chipset temperature, especially when overclocked? I've read several posts on asus forums where they said it gets too hot to touch. Thanks.

Hey, I've got a question, which RAM Do you use for your rig? I'm considering to buy a Asus M2N-E for my AM2 rig and a Corsair TWIN2X2048-6400C4 pair of sticks [800mhz, 1gb * 2 sticks] but im reallllly afraid of compatability issues... and I won't even be able to RMA it if it wont work, this is a one try thing........ can't affored to go wrong, so any advice would be appreciated, i'd like to stay within the 250$ budget range for RAM too.

-Jo.

So I finally got around to vdimm-modding my board. There's vcore-mod left to be done, but that will happen a bit later... Just wanted to drop by and add couple photos here:

I have only started testing it, but so far got some nice results with 2.70v :) Thanks again for help, guys :up:

Nice thread

I was wondering what should be the resistance values I should have to have my M2N-E (max 1.95v vdimm) offer UP to 2.3v :)

Thanks in advance :)

Well, you can use exactly the same 20k trimmer. In this very thread ^don.k's^ did this vmod on his M2N-E. Just preset it at 20k before soldering in and then reduce resistance to raise volts.

persivore's pictures disapier? Someone saved them maybe? if someone have save it, pliz attach it?

hi guys, can you please tell me to what you have connected the other wire from the resistor? i cant see it from the pictures.
And second note, i cannot boot with vdimm higher than 2.4V but its stable at 2.3V ad ddr2 520 (Corsair ddr2 667 2*1GB ram)
anyone with same problem?

Soldering pad on the top dosn't working, i will try pin7 later. For the M2N-E owners, the vcore spot doesn't exist, there is only 3 phase not 4 phase like on SLI version, the 4th choke doesn't exist so it can not be the measuring point. Use 3th choke.

I have not done vcore mod myself yet, but have you also looked at the 1st pic that ^don.k's^ added in post #22. The top soldering pad I marked on my pic was the one I was not sure about. I was waiting for someone to confirm that since ^don.k's^ marked the very very top one. Now,that I think about it, the soldering pad he marked is the correct one...

I tried and nothing happend:

http://img243.imageshack.us/img243/3017/badmodox6.jpg

hello
i was wondering if a 50k resistror wud work. so if i set the voltage to jus say 1.8v, the acctual voltage wud be sumthing like 1.95v depending on the type of resisitor used. can sum 1 confirm plz. THIS ONE: http://www.maplin.co.uk/Module.aspx?...50k%20&doy=2m9


or wud this one be better as its 22K and wud this work. http://www.maplin.co.uk/Module.aspx?...ia=22k&doy=2m9

and Wat bout this 25K: http://www.maplin.co.uk/Module.aspx?...ia=22k&doy=2m9
plz reply
thankz

hello
i was wondering if a 50k VR wud work. and if i set settings in the bios to 1.8v, wud the actual voltage be like 1.95v depending on the resistor i use.
wud this 50K work: http://www.maplin.co.uk/Module.aspx?...2201&criteria=

or this 25k: http://www.maplin.co.uk/Module.aspx?...6499&criteria=

or what about this 22k

http://www.maplin.co.uk/Module.aspx?...ia=22k&doy=2m9

which one s the best. i wud like to have a min of AT LEAST 1.9v becoz that is my rams rating

Here is correct spot for vcore mod:

http://img361.imageshack.us/img361/1413/vcoremodjm5.jpg

And the reading spot for vcore is also bad, the another leg of choke is the right one (Asus M2N-E)

Sorry, i didnt tested the vcore mod myself, i marked the points that were the same. I think my error was that i marked pin #8, now that attached pics of persivore has gone, i dont know exactly. My fault :slap:

i did the vdimm mod earlier today and it screwed thing up worse than before. i did everything as had been metioned in the thread and all i got was random crashes, any ideas

thanks

adam

hmmmm, vdrop is 0.04V in idle-load amp (if I set 1.75V vcore in load I will get ~1.71V, measured by voltmeter), any suggestion how to resolve this?

p.s. Power supply isn't responsable, 12.3V is knocked in case idle-load, for PS, idle load is the same (OCZ Power Stream).

did the vdimm mod quite a while ago with a bit of help from ^don.k's^ and i have just found my camera (moving house) so ive taken a pic of the finished product :) works great btw

http://img.photobucket.com/albums/v2...iG/voltmod.jpg

system specs are:

athlon X2 4200
2gig of supertalent pc6400 ram @ 4-3-4-8 800mhz 2.3v
powercolor x1900xt 512mb
and of course the asus M2N-E, bios flashed to 0304
Hiper type R 580w modular PSU
bunch of hard drives and a dvd burner

Hello folks... I'm trying to set up a 1gb stick from Advance Modules on a M2N-E but it won't even post, "long beep + short beeps", at first I thought was vga related but reading about the mobo I now think its the vdimm too low to boot. Unfortunately I don't have another stick around for testing...
I thought about just raising voltage a notch to see if it boots (supposedly the latest bios helps with memory stability), I just want to update the bios and see if it handles the memory at default (customer board, cant send it modded)
Would a "temporary mod" work? Is it possible to do it without soldering the chip leg? (remembering it would be only for a few minutes)
Last minute: what resistance necessary to get around 2.1-2.2V ?

i have the same question as nobre,
what resistance is recessary for 2,2v more or less?
Parkie, what resistance did you use for getting that 2.3V?

Hi, the Vcore point won't work here, don't know why.. Should i try it on the missing cap? :confused:

Vdimm works fine!

On the cap i can't measure anything too. Any ideas out there? I really need it, bcs. i have some strange Vcore "problems" with new 65nm Singlecores.

Thanks a lot in advance.

(If u need more pics, just say it)

the place for Vcore IS exatly vhere the pix shows it, i had that board and it was measurable at that point. Just place one leg to ground and anothe on the base of that coil, but be carefull to touch the coil, coz near the end its covered by some insulation crap...

Thx, but normally i know how to mesure. ;)

But i can't get anything from this leg, don't know why.. Vdimm mesuring works fine. Already tried to get the insulation off the leg, but there was none. :(

Will try it one more time, but i think it's pointless.

Try to measure the voltage at the backside of the board; some coils are really very good insulated...

I bet that will work ;)

Good idea, will try to get to the backside. :)

I just soldered a wire to the point the coil goes through the PCB. Just wanted to tell this in addition, but i think you thought of it already too :).

Check vcore on opposite leg of coil.

Tried it, but no way.. Anyhow, i already sold the board long time ago. ;)

Could someone help me with my Asus M2N E Sli? Sry for my english but im from Germany.


Cant´no one help me with my Board? Do you need Screens?

Can´t no one help me with my Board? I will overclock my CPu but that isnt possible because the vcore only gies to 1,3V.

This weekend I get to jump into an M2N32-Sli Deluxe motherboard with a Phenom II 955BE. I'm benching under DICE so cooling is not an issue. However I have been reading this thread and I have to admit I am a little lost.

Vcore & Vdimm - The Vcore mod & Vdimm mod seen here are the 2 measuring points to see the current voltages. If I connect my multimeter to those and a ground on the motherboard I can see a current view of voltages I am getting correct.

So once I see the current voltages I start the mod.
Vcore mod-
I connect a wire to a 50k VR then take another wire to a ground.

Vdimm mod-
I connect a wire to a 20k VR then take another wire to a ground.

Did I understand all of this correctly? I'm new to the vmod world so bare with me!

regards:up:

edit: I am speaking about an m2n32-sli deluxe, didn't notice the M2N lol. Is there a difference? If so... does anyone have a link that could get me on my way.

--found these, they may help! here , here

I don't understand you very well, i'll make the story short:

- You have 2 measure points, as you said, one multimeter wire(red one for positive voltages) to that point, another to ground. These measuring points aren't the ones where you have to solder the VR.

- Otherwise, there are two resistances ( maybe more ) which are related to the voltage control ( i assume the pointed resistance in the pic is for vcore mod ), the vmod points usually refer to the spot where you have to solder one wire end, then the VR and then to ground.

Again, i'm not sure about how you understood the vmod, but you have to do the mod with the power off, set the VR to the maximum value, and then, with the power on, and while you are looking at the voltages, turn the VR down, it may take a bit for the voltage to change, be careful.

I hope it helps, it sound a bit obvious to me but I don't really understand which are your questions.

I guess I need further help. I can't figure out my multimeter and everything. I have googled my specific mainboards (m2n32-sli deluxe) and my gpu (8600gt) and I know where to look, but I can't seem to figure this stuff out.

Where do I connect the multimeter to to view the current voltages, and what setting do I use? Also... I figured out how to actually vmod the chipset, other than I don't know where to look for grounds. Maybe I could get some examples or something.:up:

You gotta set the multimeter on continuous voltage, and the scale should be 2, as i said, red wire to measuring point and black wire to ground. There are ground points everywhere, the pc case itself is connected to ground, anyway, you should use a ground point near the vmod point, have you seen the pics i posted ? You can check ground points by setting the multimeter in the continuity mode ( the one where it beeps ), it will beep when you point with each wire to the same electrical point, i.e. one wire on the case, and the other over a ground point over the board, and it should beep, i hope you understand what i'm saying. It's easy to find ground spots, every IC has at least one, capacitors have one leg conected to ground...

There is something about the VR, it has 3 legs, i recommend you to "play" with it and the multimeter between those 3 legs, checking resistance and modifying it so you can understand how the VR works. Anyway i'll make you a short explanation. The two "edge" legs, have the whole resistance value, if you modify the resistance via the trimmer, it won't change if you measure between these 2 points, the point which changes is the central leg, if you set, one edge wire and the central wire, you will increase resistance turning the trim clockwise, if you connect the central leg and the opposite side of the VR, turning clockwise will decrease the resistance, this is an example, you have to check by yourself.

Once you have soldered 2 wires to the VR ( in central and side legs ), check the resistance between these wires, you have to set the resistance to the maximum value and check also that you can modify it correctly, when you have done this, you are ready to solder the VR to the vmod points.

ANYWAY, i don't recommend you to do the vmod until you are sure about how it works.

I was playing around with pencil modding the Vmem today on the 8600gt. I noticed the resistance was 526 before any pencil mods. Then I colored over it with a #2 pencil I found and the resistance decreased to the high 400 range. So basically what I concluded was the pencil mod lowered my resistance, IE greater voltage correct? - I understand things by doing them =D! If I am understanding this concept correct I believe I can work out the transistor mod.
