GTX285 various mods.. which may work for GTX260/280/295 also

[andressergio]

As always, measure mod point to ground, multiply by 20 and use a VR of that value. Should cause minimal change when set to max resistance and soldered in place.

thanks mate !

[andressergio]

no need to do vmem mod unless you want to hit 3300+ lol

the vgpu mods alone increase vmem to 2.2 from 2.1

here you go.. 10k ohm = ~2.3v

Napalm i need your help...i soldereded a 20K vr from the point you marked and ground and tuned to 10K but no go no volts increments...just one leg to the small red poing near the 3smd's and the other to ground

Any help i aprecciatte mate

Cheers

Stock :
Idle : ~45
Gaming : ~65-75
Full Load : ~80-85

Trad GTX:
Idle : ~38
Gaming : ~50-55
Full Load : ~70

700/1500/1250 1.2 volt

Boulard83 - what did you stick the mosfet heatsink on with? You really want to make sure it doesn't come loose, the fets need good cooling especially when running above stock vgpu. Also you may want to get a decent heatsink on the shader, that little thing you have on there now wont be doing much for your shader temps or clocks.

[NapalmV5]

boulard83.. thats certainly better cooling than stock but you missed 4 spots to heatsink

even @ 10k to 20k ohm vmem gets increment.. make sure you got good ground

try resistor (ex: 1k ohm) between the vr and ground.. or just use resistor alone

i tried a 10k also soldered from another point mate and no go...no increment at all stays on 2,12 loaded...its perfect grounded and soldered to the point you marked me on the red circle

following this pic measuring before modding gives me 10k form the red circle to ground...

the vgpumod i did that was crotales only gives me 2,12 max load, i left vids 1/2/3/4/11 bridged

so i dont know what's happening, should i bridge more vids ?

I installed MORE heatsink that they recommand. I used every single sink they send with this kit on every chip i could.

I can lift the card with a single heatsink. I test each one individually and they are sticked NICELLY !

For the shader .. Thats what they recommand to use ... i agree it could be bigger but this card is 100% stable with these clock/volt. I tested 730/1550/1300 and its ok with 1.26v ( im not V modded ). But i prefer to run with 1.2v and 700/1500/1250. The card perform very well and temps are GREAT !

even without any vgpu mod/s when resistance is lowered @ vmem mod ^ vmem increments

id say ditch the vr and try a 10k resistor or at least a 20k resistor or smtg in between and youll see an increment.. i guarantee you

thanks napalm just for clarifying its just that point on the red circle and no more right ? that to ground nothing more...

[NapalmV5]

the yellow circle/red dot to ground no more no less

[andressergio]

the yellow circle/red dot to ground no more no less

i have only 2 vr's will see tomorrow if i have the chance to get just resistors but this is what i did

solder leg 3 to ground and leg 2 to the red point, that measured before soldering 20k, tried also with 10k, turned a lot and nothing both cases...just cant believe that it wont work like this

[NapalmV5]

try this:
solder leg 1 to leg 2 @ vr
set vr near 20k
solder uni leg to red point
solder leg 3 to ground

[andressergio]

try this:
solder leg 1 to leg 2 @ vr
set vr near 20k
solder uni leg to red point
solder leg 3 to ground

thanks napalm will try

[andressergio]

try this:
solder leg 1 to leg 2 @ vr
set vr near 20k
solder uni leg to red point
solder leg 3 to ground

OK Napalm i did all, even used other ground point, also re soldered the mod point (the red dot on yellow circle 2) 2 times...no go it just don work on more than 2,12 load

i think i will have to forget about it

btw whats smtg ? solder the mod point direct to ground ?

Cheers

[otogrim]

Has anyone tried this on a gtx280?

[NapalmV5]

the problem with 280 its volted by volterra crap.. runs hotter than hell and limits high clocks/mods

im sorry about it mate.. ma bad.. i apologize

if you want another go @ vmem mod try that vr here at this point


same point @ post #39
http://www.xtremesystems.org/Forums/...1&postcount=39

[andressergio]

10K : 2.25-2.29v
4.7K : 2.34-2.37v

this cards are really hard to kill idk what i was doign connecting that point to ground

thank you napalm here i go again

[andressergio]

IT WORKSSSSSSSS

Big Thanks Napalm !!!, i just started testing not giving so much volts but caps mod and vmem made me pass stress test on same volts that before didnt or artifacted, now runs smooth and 0 artifacts i have my eyes twisted on watching the LCD for them

here it goes

Q9650@ 4500 /1200 2x2GB
vgpu LOAD 1,36 (barely spikes to 1,37)
vmem LOAD 2,2
drivers 195.62
GTX285@ 810/1800/3096

Great job!

[andressergio]

Great job!

thanks mate

[andressergio]

Not the cleanest job i ever made but does the job very very well

much thanks to NapalmV5 and Cryptik for the help

[NapalmV5]

your welcome sergio nice results nice clean mods!

shouldve just shown you post #39 from the beginning.. again sorry for the first mod

lol those caps ^ now your 285 looks just like my ftw

no problem Napalm very nice mod...still over 821 kicks OCP...i got the OCP/OVP vr tuned to 40ohms still got those from time to time....for ex furmark

but 810/1800/3096 solid as a rock

Cheers and Thanks

Awesomeness

What a steady hand on that soldering iron Sergio! Clean & Precise the mods really works wonders for those Nvidias.
