XFX 680i LT motherboard...vcore mod need badly

[steelballzz]

hey guys

just received this board to prepare a benching session on a lanparty next weekend....
unfortunatelly was an LT and vcore is capped to 1,6....with drop 1,56

thats not enough for my chip on aircooling......imagine with dry ice....
so i ask for some help trying to figure out how to voltmod this nice board


i need vcore and vchipset.....vdrop would great too

i leave here some pics

ADP3189 is the same as what they use on the P5B if im not wrong... Check out the datasheets at Analog Devices, they list the grounds, etc.

Hi,

Probably can be the same vcore mod of eVGA 680i SLi, or not?



Help

^ Looks like the same mod. Is the board a reference model?

...and... green PCB??

[justin_c]

Just measure the resistance with a DMM and check if it is it. If it reports the same resistance as given on the Vr-zone site, then its it.

Yes..

both are the reference boards of nvidia..

green pcb is 680i LT
black pcb is 680i "normal"

green pcb is 680i LT

Ahh.. gotcha.

Forgot about the LT versions. I just thought they might have done the same thing they did with all the 8800 cards (first black, then green)

They ARE the exact same.....so keep on.....

thank you

we will take care of that today

Hi,

We tried the vcore mod right now but no difference on vcore value

[steelballzz]

we measured the resistance before the pencil mod...
we had 0,86
after the pencil mod we had 0,54....
aparently the mod worked but there was no change in vcore.....


we really need to get this board to give more vcore

any help would be great

The method to measure vcore was ...? bios or multimeter?
If not measure on the back of the mobo...on the coil.

[N3RO]

BIOS.. probably the vmod can result but the BIOS does't read any vcore above 1.60v

The measure point is not the same of eVGA 680i

[VoRtAn_MaDgE]

The measure point is not the same of eVGA 680i

Yeah i know.
Try this ...

between cpu socket and mosfets ramsinks...

Read front and back of the mobo.

[N3RO]

I'll try this tomorrow (today hehe)

I'm not with the board here

thanks vortan

[VoRtAn_MaDgE]

The two "R50" above cpu socket (back of mobo)...
Mosfets near too (front of mobo).
If reading fails check what underneath the mosfet ramsink above cpu soket

Good luck N3RO

Thanks,

I'll check this tomorrow.. Depois de visitar a alfandega para trazer as fatbody do steel

is there a vdroop mod?? pencil mod will be nice

[steelballzz]

is there a vdroop mod?? pencil mod will be nice

we couldnt put the vcore mod to work.....
i guess its not the same as the other board

didnt tested the droop
