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

[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.

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.

At 300ohm I got 1.28v load with Furmark, but other less intesive apps. around 1.25v. I wanted to try and get 1.28v when running something other than Furmark, so I brought it down to 200ohm.........no difference. Not sure why some of us are having issues with this, but its a little strange.

Only time will tell, we are the guinea pigs

well Now I'm around 290-300 ohms...still no difference.

Looks like I really need to revisit the bridging.

1/2/3/4/5/11 are bridged right now...

should I do 12 and get rid of 5? From what I was told in this thread, doing 5 or 12 will give the same results....it doesn't matter doing 5 or 12....any results that prove otherwise?

EDIT: Can someone post a picture of their bridging work? I'm also curious to see how the conductive ink was used...

EDIT: Redid my conductive ink...I got rid of 5 and did 12 instead....so now I'm at: 1/2/3/4/11/12 with my resistor at 290 omhs. I'll test when the ink dries.

EDIT: Okay, getting better results now...Got rid of bridge 5 and bridged 12....now using 1/2/3/4/11/12 and I'm getting 1.26 on load...about 1.263 to 1.268 The only thing I can think of is to better the bridge connections...i'm using conductive ink....i'll try an improve the connection with the ink, may later switch over to solder and a tiny lead. I still have yet to see 1.28

[NapalmV5]

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?

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.

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?

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

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...

theres no other step just step 1 -> step 2

if your not getting higher voltage from lower vdiff resistance.. you have to redo your penciling

pencil modding is unstable.. even if you get lower resistance doesnt mean you get higher voltage

vdiff mod is not working

you gotta pencil/repencil till you get an increase in vpgu

ive guinea piged vdiff thoroughly

btw nice clocks

you guys are fine.. if you do worry than why would you even want to oc ?
