Vmod For Evga 650i Ultra Help

[Vatos_locos]

Hi every body i'am new here first of all exuse me for my spelling i'am not good at english and i'am from Greece

so let's get to the point

my system is :
Cpu : E4300 @ 3,5 Ghz stable @ 1,44 V
Mobo : EVGA 650i Ultra pic ---> Linky
Mem : Team Elite Stock Timmings @ 1000Mhz @ 2V

the problem is ta the Board looses 0,4 volt than the Bios Valeus and under load it drops more
and couse i can discribed it well couse my speling some pic's might help

so i need your help to mod the board Vcore and some Vmem (only 2,1 On bios )
i can do the mods easy i have the skills and i know how to solder couse of my work
so if anyone has any idia would be very usefull i havent yet idintify the compoments in the board couse i'am writing now with this pc so ask whatever you want

Can anyone Plz help me ?

I'm curious about this as well.
I have an eVGA 680i board and I haven't been able to find any information about volt-mods.

....And God knows, they need it.
These boards are great but suffer from a terrible vDroop.

[Envydia007]

how terrible?

[evoic]

If I set 1.5v in the BIOS, I can expect an actual voltage of 1.45v - 1.46v if I'm lucky.

Under load, it dips again, but far less.
Basically, a typical set-up would be:

1.525v for 3460Mhz
1.475v Actual
1.465v - 1.47v under load.

So if the board is being nasty - I set it at 1.525v and only get 1.465v under load.

That makes it pretty damn tough to get an awesome overclock when the voltage is dropping like that.

Luckily, I have a great E6420 that compensates for some of what I lose on the board itself.

Since the BIOS only allows you to go up to 1.6v, the most I could ever put to the chip would be about 1.54-1.55v's MAX.

.....Well, I guess that will extend the life of my chip in the long-run, so maybe eVGA is doing me a favor.

[Vatos_locos]

indeed they are great boards but look at this



the real voltage is 1.43 V the Voltage in Bios is set at 1,47
so it loose 0.04V and if you see the speedfan photo you can see a BIG Vdrop on load
so that keeps my E4300 from going up to 3,7Ghz althos i don;t have any idia of the Chipset Voltage the board has same settings to get it up to 1,50 but i don't know how to mesuere it it might be this the problem if the board looses and on the chipset i will never get more Mhz so thats i'am asking for help

[Tomasz25]

has anyone seen Vdimm mod for this motherboard, i'd like to get 2,3V becouse 2,1V in BIOS is to low for my RAM, Please help

[zorz]

@Vatos_locos:
I have the same problem vith my XFX board. It looks the same as eVGA and i need too the VDIMM MOD...

By the way, those are the made nVidia boards solding under XFX, eVGA, BFG name(brand)...!!!

[Vatos_locos]

yheap i know it i found the mods for the Nvidia 65i sli but it did't worked on my board eny idia ? i have seached all the internet but noone has worked with this board on Vmod's it'a a shame couse it's a good board and if someone coude make somethink it will clock more naw i can't get more than 1,54Volt on my cpu so i'am stuck @ 3,6 Ghz and i know my chip can do more but i still have the Drop

[Vatos_locos]

i think this is the controler that board uses (Nvidia 650i Ultra T1) eny help now ? i did pencil the first resistor on the fb leg with no results on the vcore

[Vatos_locos]

bump anyone ?

[Bei Fei]

I am also looking for vdroop & vdimm for EVGA 680i A1. Please if anyone knows the basics of soptting these mods I can help with this board. I have strong EE background.

[Vatos_locos]

Bei Fei take a look @ this http://www.vr-zone.com/?i=4215&s=18

[ineedaname]

Well the chip is the same one used in many asus boards like the striker extreme, p5b deluxe, p5k deluxe, p5ne sli and so on.

you can look for an example here:

Though the pencil mod should be ONE of these two marked resistors in the pic below.

I can't really tell from this picture. You'll have to take a better pic of the area shown in the pic. But on the other hand it shouldn't kill your board if you do decide to go with trial and error. Just erase it if you don't notice any vdroop difference. And of course don't make the marks too dark.

Oh and just to let you know its probably the brown one and not the greyish one.

[Vatos_locos]

ok i test the drop and somthing weard is going on but i think it is good for me

if i set the voltage 1,45 in bios i get 1,44 on idle BUT on load i have no drop but my voltage raised up so on load i have 1,45 WTF ?

ineedaname thank you so so so match it worked fire to me now

[bean_laden]

^did u pencil at told by ineedaname ?

[Vatos_locos]

yes i did i pencil the cap on the right on the image ineedaname show us 2-3 times with the pencil is ok then you i got 0.01V drop on idle but on load i have 0.000V drop weird ha ?
