^ sounds like vdiff is the only working mod and vid bridges dont make connection even though it looks like it makes dont mean it actually does

for those of you using silver ink:

anyone not getting 1.30v @ load from doing vid bridging and vdiff mod (step #1 and #2 @ guide) suggests a redo of the vid bridging mod until 1.3 is achieved

if you guys want accurate/actual results from these mods please dont use silver ink

i dont and i believe neither cryptik recommends it.. and do one step at a time that way you can move forward to the next step confidently

heres how i do it/done it..

- i cut a 2mm long lead from resistor/capacitor leftovers

- in one hand holding the tweezers holding the 2mm lead i place/hold it over the two points

- with the hot iron in the other hand i come over and kiss the 2mm lead just a smooch

thats it done!

and can easily be removed.. place tweezers over the bridge make sure you got a hold of it and just kiss it again with the hot iron and its gone

easy breezy :)

edit: since bridging # 2 is the most important one.. if you follow my bridging guide just do # 2.. if youre confident enough to go ahead with other bridging go right ahead.. but if not just do # 2

Yeah Im using an ink pen, which was packed in a box in my attic for 2 years :p: Im gonna pick up a new one, re-bridge 1 by 1 and see if that does it.

Ill have to try this if the ink doesnt work. Had no idea you could do that without solder.

Thanks again for all this info. NapalmV5, much appreciated! :up:

ya...u was right i also got this problem before i solder the bridge .
the conductive pen looks good but just dun work .
solder works like miracle.
i spend too much time on draw and cleaning and redo for ink pen.
i guess the solder spot was small ,even after solder can be easily redo without trace if RMA needed....
thkz 4 your hard work NapalmV5...
without these mods i won't buy my gtx285...it's sooo boring to own a unmodifiable card ....

I use Quick Grid repair compound from a rear window defogger. Worked like a charm, can remove with a q-tip..

And while I would recommend a solder point as well. My nervous hands made enough of a mess with the compound, i think i would have a molted blob of solder resombling a 285 if i tried it.... :(

does any one knows how to enable SLI with 280 & 285?

i figured out i need to flash, i'm aiming the 285 bios into 280

can anyone give some tips here?

evga: ssc vs ftw

pcb: 4808 vs 5008

cooling: stock vs stock

actual clocks: 756/1764/1512 vs 799/1692/1494

Those pcb number are looking more like week of manufacture of PCB's....4808 / 4908
Will be interesting to see if we get 0109 pcb soon :D

Have you got an FTW as well now ?

thinking about doing mod #1 to my 285...core craps out at 750 which seems awfully low. My 280 did 770 and could have gone higher if it wasn't for the shader, which I'm pretty sure is thanks to the evga voltage tuner. I have a request though, could someone post a picture of the vids bridged so I know what it's supposed to look like? I've never done anything with a silver ink pen and don't want to :banana::banana::banana::banana: something up. If someone could post a pic asap I could go to radio shack immediately and do this within the next few hours and then test clocks later on tonight. Thanks in advance!

am i reading this right?

lower clocked ftw bios has higher score???

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

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.

I redid the bridges today(this time with solder),removed the graphite off the resistor to start from scratch, and Im getting 1.21v with 2,4,12 bridged..............weird :p:

Removed and resoldered the bridges twice to make sure they were making good contact, and they looked good each time.

Gonna try again now, and maybe just bridge 2 alone to see what I get.

EDIT: Hmmm I just rebooted, and now Im getting 1.25v Core, 2.15v Mem :shrug: Is that what I should be at, or still a little low?

Yep, that's the voltages you should get doing stage 1. Penciling the resistance of the smd down (stage 2) should give you a little more than 1.3V loaded while doing stage 3 could make you max out at 1.39V.

Thanks! I shaded down to 297ohm, and am getting 1.28v core\1.15v mem. Ill see what kind of clocks I get with these voltages, and if I see a good gain from 1.23\2.11 Ill shade it down a little more.

Thanks again for all your hard work Napalm & CryptiK, much appreciated! :up:

now it sounds like bridging mod works but not vdiff

i had the same thing happened to me yesterday after ive recapped my ssc.. i repenciled vdiff resistor and even though resistance was down where it should be i got undr 1.3vgpu @ load

vdiff mod since its pencil it can get unstable.. just have to pencil till you get ~1.30vgpu @ load

guys dont make it too hard on yourselves.. if you solder bridge and your getting 1.24-1.26vgpu @ load you are done with step 1.. you dont have to resolder.. go to step 2

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 ?

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.

Does the FTW have the same VID layout as SSC from the factory ?
