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

[Orangeblast]

the FTW is just a better binned card...its then flashed with a BIOS that reflects the higher clocks of the FTW. The volt mod remains the same from the factory as the SSC cards.

Is this confirmed Orangeblast....have you got one to compare ?

[Orangeblast]

Hah, wish I had one, so I can't confirm this...its only what I hear....and knowing how the industry works with these products. I was in it not too long ago.

[G4h4o8s6T]

ok.. youre on the right track now.. its not so much the resistance now.. you got the necessary resistance.. it has to do with how well the pencil works on the resistor.. just pencil over a bit more till the resistance works better

your welcome and hope you get some extra mhz out of it


btw voltages @ load or bootup ?

Yeah its workin great, Im using a 2HB pencil so took me a good while to get down to 297ohm. Im gonna shade it down a little more regardless of what clocks I get now, probably to around 1.32v max.

At bootup I think it was at 1.23v, idle 1.08, and load 1.28v.

ohhhh....i think it finally make sense now...so you would be bridging the top and bottom portions like you would do for a pencil mod. for some reason i was thinking that when you guys said bridge #2, #4, #11, or whatever, you meant connecting for instance, 2 and 4 together with a trail of silver ink. that's why it seemed so wierd. so it should look like this, right >>

edit: what do you mean by "hot iron"?

edit 2: in my image, i think it's the middle part that's raised instead of the outside, i dunno how these things look close up.

Yeah all your doing is drawing a line between the two points, like shown in NapalmV5s guide........

[NapalmV5]

am i reading this right?

lower clocked ftw bios has higher score???

man o man

That's really weird... I actually thought Napalm messed up something with his writings and those pics.

When you push the shader clocks too high the score goes down in most benchmarks.

You've got to find the right balance to get the highest scores.

yap that's true

thats not ssc bios vs ssc @ ftw bios.. ftw is my 3rd 285.. so thats ssc vs ftw

clock for clock: both same performance.. though the ftw can clock/sustain higher core

[NapalmV5]

if above 1.26vcore @ load i can assure you vdiff mod is working

without vdiff the max allowed is 1.26v

yeh vdiff mod = 1.32-1.33v max

[MurderCityDevil]

success! picked up a conductive ink pen at, of all places, awful microcenter (neither radioshack or even fry's even knew what I was talking about), and bridged 2/4/12 on my vanilla 285. Checking idle/load volts before resulted in voltages that seemed too high on stock - idle was 1.1-1.19 and load was 1.21. Bridging the first time resulted in a load temp of only 1.23. I figured there was poor contact so I redid it, and now, crazily enough, my load voltage is 1.28! vmem is 2.20. this is without any penciling mods. Is it possible that some cards just have higher voltages for some reason? Either way, 1.28 is very respectable without lowering any resistance. Thanks to napalmv5 and cryptik and everyone else who contributed! On to test my max clocks

edit: forgot to add, this was all done after flashing to a ftw bios. perhaps that's the reason I got such high results?

[Orangeblast]

Well, tonight I'm going to go ahead an get this a try...

I'll show some results and stuff. If you don't hear from me, something bad happened. lol


EDIT: Okay, made the mod to just 1 of my SSC cards. 1/2/3/4/5/11 are now bridged, however to my dismay, I'm only getting around 1.228 volts...which is a bit far from the expected 1.26

I hard modded it with solder and a tiny lead...

I noticed that some people did bridging on 1/2/3/4/11/12 ...is this what I should have done? Any when I solder it, should I run solder straight across to bridge it and get rid of my tiny lead?

Even with 1/2/3/4/5/11 i think you should still be getting around 1.25v. Doing 12 instead of 5 seems to be recommended by NapalmV5, but gives the same results.

I just bridged with solder, but using a lead as well shouldnt be a problem. It could be one of your bridges isnt making contact, so maybe try using your DMM and test the resistance between the bridges to see if you get a reading.

edit: forgot to add, this was all done after flashing to a ftw bios. perhaps that's the reason I got such high results?

I doubt it, just because its been found softmodding through bios/software is a no go with the 285. Can you check the resistance to make its the same as ours at stock?

So I was playing around with clocks yesterday, and was wondering why I could run Furmark at 19x12 for 10min, but would black screen immediately when starting up RHDRIBL(defaults 640x480), and get artifacts while watching movies in WMP.

Heres what I figured out with my load voltages.........

WMP- 1.24v/2.13v

RTHDRIBL- 1.25v\2.13v

TF2- 1.26v\2.14-5v

Crysis- 1.26-7v\2.14v

FEAR2- 1.27\2.15v

Furmark- 1.28v\2.16v

So has anyone else noticed this, and is it normal? Not that big of a deal, just tune the resistance down to get the desired voltage while gaming, but kinda annoying when your stability testing.

Okay, well I was able to get the resistor down to 340 ohms...both of my SSCs.....and I went ahead and got rid of the leads and used conductive ink..so hopefully I get the full Voltage and hopefully get a boost.

I haven't tested this new setup yet, but from last night during my first test I did see a slight boost from 735/1656/2800 to 745/1656/2850...nice boost, temps were still good as well.

Once I get my Koolance water blocks, I should be seeing some great gains.

[Fosco]

Have tested FTW bios on Vanilla now.. It worked fine in Vantage with def FTW clocks. Have never been able to run vantage at that shaderclock before (1620 on FTW) , But Crysis warhead keeps chrashing on me.

Yeah you'll def. see some good gains, these cards shine with some volts on water. Haven't tested thoroughly but went from 756/1584 stock volts to 810/1836 1.28v

Okay I am having the same issues as some of you guys in that I have gone through all the steps and am getting only 1.26v under load. I have a XFX Black Edition and started out by using conductive ink for step 1, 2b pensil for step 2 and a 500ohm VR tuned down to 150ohm for step 3. After reading all the posts I removed the conductive ink for step 1 end replaced 2, 4 and 12 with tinned wire (thin wire). Another issue is that the SMR from step 2 starts out at 1.07kohms, that seems much higher then what it should be. Given that however I was able to pencil it down to 330ohm with my 2b. And i'm still only at 1.26v under load! What am I doing wrong? Please help!!

Yup, this is EXACTLY what I'm experiencing as well. I've got the resistor down to 340 ohms......I've done the bridging on 4/5 along with the already 1/2/3/11 bridges.

I'm only getting 1.26 volts during furmark testing....

I can also confirm that I too am getting different voltages depending on what application I'm running....

During Vantage testing, I get around 1.24....during Furmark testing I get 1.26....
Wonder why its not consistent.

Any suggestions for us guy running in to the anomalies?

[KingK76]

This question is for NapalmV5. I have followed your modding adventures with the GTX 285 in various forums and you have done many mods to your card (s?). My question is, have you tried your 3 step vmod method on a fresh card (one that you have done no other mods on)? The reason I ask is perhaps you have unlocked something along the way to allow you to hit 1.36v that is in tandem with the 3 steps you have shown all of us. Please don't take that the wrong way as I appreciate greatly the work you have done. Thank you.

Yea, its strange, almost seems like we missed a step or a step wasn't mentioned. I dunno......

[Orangeblast]

if above 1.26vcore @ load i can assure you vdiff mod is working

without vdiff the max allowed is 1.26v

yeh vdiff mod = 1.32-1.33v max

I just saw this post....I'm only getting a max of 1.26V....and you mention that "without vdiff the max allowed is 1.26v"

so......what is the vdiff...I must be missing something here...

EDIT: nevermind, vdiff mod is the shading of the resistor..I'll try to get it lower. as explained by Napalm, don't go lower than 200ohms, currently I'm at 340...I'll try to get it down to 300 and retest to see if it makes a difference. If I hit 1.27 then I know I'm on to something.

I also pass Furmark @810/1836/1512 with 1.24 vcore, but I can't pass 3D06. I thought that Furmark is most stress test for video cards, but it turn out it isn't
Here is Vantage, Win7 x64, @783/1800/1512 - 1.24 vcore

If you read my post above on load voltages you'll see why it passes Furmark, but not 3D06. If you haven't measured load voltages while running different apps, then I suggest doing so, cause your most likely getting less volts at load when running 06 than other intensive apps., like Furmark.

EDIT: I measured load voltages while running different apps:

Furmark 1.6.0 - 1.23-1.24v
Crysis - 1.23v
Crysis WH - 1.23v
Stalker CS - 1.23v
FEAR2 - 1.23v
FarCry 2 - 1.22-1.23v
Vantage - 1.23v
3D06 - 1.22-1.23v

[Demo]

How much is tha max safe temp for 24/7 stock cooler use if i perform the ink mod that gives 1.26(core) and 2.15(ram) ?

Aside from Warhead, Furmark , 3dmark05/06 what other stability testing tools/methods should i consider?

I have a similar question - anyone know what the max safe voltage is for the 285? I would assume its less than what the voltage tuner gave for the 280 (1.3v) since a 55nm core is more sensitive to voltage?

Is running 1.25 idle and 1.28 load 24/7 going to reduce the life of the card, or is this within limits? I may just go ahead and do the pencil mod to try and get 800 core.

This is very common
every app has its high and low volt reading areas.some cards are more spikey then others too.
in genral when doing a volt mod make sure to read volts thuogh the whole benchmark app you use as to make sure your not hitting any ovp/ocp which would lead to blackscreens.

[Fosco]

im gonna do that if/when @ vapochill

step #1
- simple way to increase vcore from 1.15v reference

1.26vcore @ load

Does this give more vdimm to ?

[Orangeblast]

Does this give more vdimm to ?

Its suppose to...bug...even after rebridging 4/5 it still didn't make a difference.

the best I can do is 1.26 during furmark testing

I have some koolance blocks coming soon so hopefully...my clocks get better.
