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

[NapalmV5]

if its not your first time modding why bother with conductive ink..

you guys see what is being used to bridge.. 0 ohm resistors

on the front of the card.. how many vid diodes (D14 thru D21) your 285 has and which numbers are occupied ?

D14 D15 D19 ?? if so only bridge vacancies @ 1/2/3/4/11/12

[VoRtAn_MaDgE]

Did you check the edit in the post above ?

About your question is easy... if i'm stock cooling with bother making a hardmod if it's faster with conductive ink ?

Gonna remove the heatsink and see that.

if so only bridge vacancies @ 1/2/3/4/11/12

already tried, 1.2v load, mentioned 2posts above

[NapalmV5]

1. remove the cooler and lets be certain its d14 d15 d19

2. if you got d14 d15 d19 as all 285s based on this pcb do then your conductive inking is not successful

if you want to stick to conductive ink you got to redo your inking until it is successful

soldering+solder is much faster and ~100% effective

I agree with you 101% about the solder subject,already explained why i used liquid silver...same method that i used in the past with 8800gts.

I'm gonna remove the cooler and check the vids.

My vid area...

[NapalmV5]

you see why: only bridge vacancies @ 1/2/3/4/11/12 (d14/d15/d19)

if properly bridged you get the voltage in the right neighborhood always

if you want/need a bit more voltage.. plant a diode @ d18 + bridge 9 and 10 for total of 4 diodes/8 bridges

Yeah i see but...

Tried with solder and liquid silver...

1/2/3/4/11/12 - 1.19v
1/2/3/4/5/11/12 -1.20v

No matter if liquid silver/solder

Check conductivity in both cases and the resilts are the same...mod working but only 1.2v max

Gonna try the hard mod (vgpu/vmem/ocp)

Regards.

[NapalmV5]

heres the fix.. which im also gonna replace step 2 with

this little bastard is the reason why some of you are @ 1.2vgpu after bridging (resistor @ over 10k)
this little bastard is the reason why some of you are @ 1.3vgpu after bridging (resistor @ under 10k)
this little bastard is the reason why solid color screens still kick in after ocp mod



i dont need any confirmation but which one/couple of you would like to confirm this mod for others ?? thanks

first post revised/updated.. happy ocing your 285s

I'm not crazy so

Ok i'm gonna confirm that tomorrow, see if default value is 10k and pencil it down to 5k.

But with that resitor mod i'm gonna get more than 1.26v after step 1?

Thks.

I wish you my best from South America and a better 2010 for all, in this awesome thread, thanks to my mates cryptik, jor3lbr , napalmv5 , leeghoofd , OC Nub and so others for the big help always, let us 2010 brings us peace, love, and better and faster hardware , of course that can always be modded

This years has been special for me as 2010 will bring my first kiddo Valentino

here you are meet him

yes close to 1.35v

[VoRtAn_MaDgE]

yes close to 1.35v

Hmmm... maybe that's too much for 24/7 stock cooling.

Maybe better doing vgpu/ocp crotale way to regulate voltage below 1.3v

same here sergio.. wish you and your family a happy/healthy new year

looks like your kiddo is in good hands ^ angel holding him while he sleeps

so now its not ok ??

you think crotales vgpu is better ?? ok fine dont even bother with the mod ive posted above

itll screw up your 285 anyways

You miss understood me m8

What i meant to say is that having 1.35v stock cooling no matter the kind of mod i guess it's too much, don't you think ?

With the one posted by crotale we can regulate the volts as we want.

If i could get 1.25/1.26v like posted by you it would work like a charm...you can see that i tried that mod first not the other way

I'm gonna measure the resistor default and see the increment of voltage in small steps ... maybe possible

[NapalmV5]

oh i got you clear.. yesterday you got on my nerves with your inking.. but once you confirmed with solder i came up with a fix/mod.. now you just want to piss me off.. fine no problem

if all these steps cannot be regulated the way you want why bother with these mods then ??



to those of you that want to do step 2 you dont have to drop resistance down to 5k straight.. you can start @ 9k and lower from there

[andressergio]

same here sergio.. wish you and your family a happy/healthy new year

Thank you for your kind words napalmv5

Cheers

[VoRtAn_MaDgE]

Because everybody except me and Demo gets 1.25/1.26v load with your mod and that's the voltage i want 24/7 - Simple As That!

In my opinion above 1.3v is too much for stock 24/7 but as i said before i'm gonna test your way (the method you posted with my pic) and see if i can get that voltage.

Thks for the help.

andressergio

Best of luck in 2010 and be patient.... hopefully it will be full of health and very funny

[NapalmV5]

FYI every vmod ive posted is adjustable.. can be regulated to your liking.. can be regulated to your cooling

what dont you understand about my vmods ??

read this again if you have to about the new step 2 mod:

this little bastard is the reason why some of you are @ 1.2vgpu after bridging (resistor @ over 10k)
this little bastard is the reason why some of you are @ 1.3vgpu after bridging (resistor @ under 10k)

only if you attempt the mod youll understand why it works if you dont now

you want 1.25-6vgpu?? how many variations you want ??

after step 1 (1/2/3/4/11/12 bridged) you can adjust the resistor @ step 2 to 10k ohm and get that voltage

if the resistor is already @ 10k than lower (maybe 9.7k 9.5k?) resistance until 1.25-6vgpu is achieved

or

after step 1 (1/2/3/4/11/12 bridged) skip step 2 do step 3 @ 100-150 ohm resistor and get that voltage

simple as that!

and i can give you several more diff ways on how to achieve that voltage

Thank you mate

Btw im using 1,37 vgpu / 2,2 vmem for 24/7 idling at 1,17/2,16

Should be no harm if temps dont go extreme high

Cheers and have a nice nice 2010

With 30C outside summer here i used my portable AC to push 10C to the rad, room ambient was at 23,2, here are some results

Hey Guys

i need a vgpu mod and maybe ocp mod for my Inno3D GTX285. PCB is rev2 like the EVGA Vanilla. http://www.xtremesystems.org/forums/...&postcount=461

Found OCP here: http://www.xtremesystems.org/forums/...&postcount=498

But still looking for vGPU Mod :/

Would be great if you could help me with it

[Brama]

I have a couple of questions:

- on first picture (page 1 of this thread) of Napalm mods there is a 10 ohm resistor connected to ground labeled OCP mod, from same point of Crotale mod but he suggest a 15 kohm resistor. Why this difference?
I put a 15 kohm between Crotale point and ground but sometimes I have OCP triggering in, even at 1.29 V. Which resistor value do you suggest?


- I connected also the 150 ohm resistor of Napalm mod #3 to ground (mod #1 and #2 already done) but I have only 1.29 V. Can I lower or increase this resistor to get more volts, i.e. around 1.35?



Thanks in advance and bye.

sup mate happy new year

yes but crotale suggest a 100k vr, and tuned to 15k i got mine tuned to < 1k and if if go over 821 or raise vgpu on more than 1,4 i get same triggering, we where talking to napalm and not 2 cards are the same and maybe other thing triggering...

what i did as you can see on my clocks thats my gamming clocks, but benched on 4700mhz Q9650, i used GPUTOOL to find max core/shader/mem at my 24/7 4500mhz and that was awesome as those clocks are the perfect combo any variation i get lower scores and FPS...i did that at 1,36vgpu load and 2,2vmem load

you got to do step 2

heres the fix.. which im also gonna replace step 2 with

this little bastard is the reason why some of you are @ 1.2vgpu after bridging (resistor @ over 10k)
this little bastard is the reason why some of you are @ 1.3vgpu after bridging (resistor @ under 10k)
this little bastard is the reason why solid color screens still kick in after ocp mod

step #2
- this step is a must after step 1^ if only 1.2vgpu is achieved
- lower resistance (ex: by pencil) to 9K ohm at first then lower from there
- mod increments vgpu ~1.3-1.38

Is the connection 3 on SMD component a ground? If yes, I suppose I could connect a simple resistor of 15 K between point 2 and any ground nearby.

Do you agree?

ocp mod

i want to make sure you guys do the ocp mod properly if/when not following crotales guide

yellow encircled red point to ground


note: use fixed 10 or 100 or 1000 ohm resistor whatever you guys are comfortable with

i gained @ 10k ohm resistor/i gained @ 1k ohm resistor/use whatever fixed resistor you got between 10 ohm and 1000 ohm

sure you can try a 100 ohm resistor @ step 3
