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

[Orangeblast]

only 70c with all those Volt mods?

[MisterMagoo]

Yep. Running stock speeds FTW bios.

[Orangeblast]

you didn't get any more gains from bridging all those connectors and doing the pencil mod?

[MisterMagoo]

I did, but I dont need to run that 247. I get 70 fps 1920x1200 8x AA in crysis wars. But for benching I run 760/1700/1480 for now. And I just did the bridging, not the pencil. I basically just made my cards FTW.

Also FTW speeds are 720/1620/1390.

[Orangeblast]

My SSCs both do 735/1656/2800

I really got to get off my butt and try these mods out...I'm sure i can achieve 800 or so on the core and at least 1750 or more on the shader.

The shader is only restricted by the temperature, so if put these 2 beats on water I should see some huge gains.

[MisterMagoo]

Temp never held my shader back. My first 285 vanilla does 775/1760/1550 easily. My new one isnt broken in yet but I can tell it is loosening up a bit.

the added voltage didnt really affect my temps either. I have read a few times about the higher temps holding back the OC on these. Not meaning that it is overheating, but just that the clocks respond better when the temps are cooler. I know my card didnt overclock any better with added voltage, and temps seemed to max at 73c when it would crash, where I have seen as high as 78c on stable OC with no issue.

I ordered a HR 03 GTX and Im trying to find the VRM heatsinks. Had some correspondence with thermalright, but if anyone knows an online retailer that carries them let me know..

[hehee]

vanilla 285
solder link 1/2/3/4/5/11...=1.22v
try to shade resistor ,but too hard to shade it to desire ohm value...
finally solder 500k vr...trying at 1.3v...warranty void....hehee

[NapalmV5]

i penciled the vdiff resistor down to 100 ohm with a #2 easily

its more than possible just gotta try diff pencils

the lowest resistance that works is 200 ohm any lower and protections kick in..

330 ohm or 200 ohm both same 1.33vcore @ load

vid pins are holding that back from any higher

unfortunately looks like even vids are limited to this voltage

i got a 330 ohm vdiff resistor on the amp on which i moved d19 to d18 and still 1.32-33vcore.. 2D @ 1.24

then i removed d18.. same voltage.. the only diff 2D voltage returned to normal 1.08v

[10acjed]

What would you recommend on leads, I managed to find 6B at office depot. Seems the HB are very common, all i see everywhere else..

I am just awaiting the HR 03 GTX with xtra VRM heatsinks to get in stock, Thermalright shipped them out to resellers this week... But I figure when I have it apart I want to shade it as well as possible and see if I can get any clock gains with cooler temps...

[nickless]

I also managed to reduce the resistance with some 21/2=HB pencil to 290 ohm. I've cleared everything and made the hall mod again, but it gives me only 1.24v again. It looks like 1.33v is a dream for may card without hard vmod

Guys, how come no one else is reporting any gains from this mod? Certainly this thread has been seen thousands of times and certainly some people have performed some of these mods as simple as they are.

Fo the record, I used a silver conductive pen last night on 2 and 4 and gained nothing on my vanilla eVGA 285. It was already a great overclocker, but it seems if these voltage mods were actual, they would produce better results.

Not sure why no one is really gaining anything worth noting. I admire the effort involved here and I'm not downplaying what's been accomplished, I guess I'm just wondering if it's even worth it if no one is gaining anything and it seems that the same 4-5 people are the only one's posting in this thread. Where are the others with their results?

[10acjed]

good question... and these mods do work in the sense that reading the voltage before and after the mods shows the exact change.

However the additional OC is yet to be seen. As well with the ongoing bios/software modding it seems these gpu's could care less about the added voltage, they just dont want to run any faster.

[NapalmV5]

after getting a pm about a recap gone wrong now this ^ *sigh*

goodness sake guys! i only recommend the back to be capped @ C561-4

i do not recommend recap of the panasonic 330uf spcaps and sanyo 220uf poscaps unless you know well what youre doing.. and i posted on how bad the card got after that recap.. took a number of recaps to get the hang of the gpu/mem

looks like ill have to revise/delete posts



what miracles do you guys expect from such low v increment ? i was already at 1.26vcore load.. now @ 1.33

fake voltage?? well i guess a 1.38vcore at which temp rise higher than at 1.26/1.33 is fake too..

1.38vcore via step #3 is too much for stock cooler/thermalright hr03/air

im looking and looking and i may just get more vcore via other means but i only got so much time i can spend on the 285 and im doing it all alone by myself with my very limited knowledge the only help came/comes from cryptic here @ thread.. whom i owe another thank you

What do you mean actual voltage? It is there no doubt...everyone has tested with a MM and showing the increase in voltage...how could you refute that?

I saw major gains on one of my cards. Also note that HEAT kills OC no matter what, there are people without the volt mod doing 800 on the core with water so....imagine what it would be with it.

If it was not for this thread I would have stepped up to 295 I am glad I didnt because I spank 295s all day long.

[SAE]

Upping the voltages using the crappy stock cooler ain't cutting it. When you're getting temps like 85-95°C under heavy load unmodded, what do you guys expect from upping the volts??? BBQ??? <- you should!

Cooling is evident for clocking the shader core, I might even state it's more important than increasing volts. You always should improve cooling first.
Just my

What I meant by actual voltage is that maybe it's possible those voltages are bring measured but not actually what the GPU is seeing. Maybe there's other components in the circuitry preventing the GPU from receiving the extra voltage from this mod.

My 285 has yet to break 73c under 100% fan load during loops of Crysis and will often run in the very low 60's for any other benchmark. If heat is the real issue we'll know tomorrow when my FC waterblock shows up, but I'm doubting that's the issue at this point. While I'm certain I'll gain just a slight amount from watercooling, I don't think any additional voltage from these mods are going to push it any further because my experience with this mod so far hasn't shown anything.

And what do you mean by spank 295's? If you're using two 285's you would, otherwise a 295 is still a faster than your overclocked single 285 by a considerable margin.

As stated above, my temps aren't exceeding 73c under the worst conditions and often remain in the low 60's for normal use gaming. Watercooling should bring that down to the high 30's or low 40's but I still doubt cooling is the issue with this volt mod simply because voltage can overcome heat to a certain point and I've seen ZERO results from this volt mod. I think there's something else holding it back that hasn't been realized yet. As stated by many others here, it's a bit strange that temps aren't going up at all with this volt mod either, which also leads me to believe the GPU isn't actually seeing the increased voltage.

We'll find out tomorrow though after I watercool my card. In the meantime I've removed the volt mods since they didn't do anything. I'll re-do them after I get my max OC numbers with a waterblock. If I'm wrong and the volt mods, I'll certainly come back and scream fantastic, but if they don't, I'll also report no gain.

NaplmV5, I apologize if I seemed ungrateful in that post. I am no way ungrateful for the effort you have put into this. And thank you for the hard work.

Same here and I've already stated once in this post that I appreciated the efforts that went into this thread. Negative results shouldn't be viewed as negativity but constructive criticsm to help find out why there aren't more positive results from this mod. I'm simply trying to say that maybe there's something else holding back this volt mod. Not sure how it got misconstrued any other way as I thought I was quite clear in my posts.

However, maybe it's just that these cards aren't really limited by voltage as I've noticed that even with eVGA's recently released voltage tuner for the 260, 280 and 295 that many people aren't gaining anything either.

Did you actually measure vgpu and vram after and before modding? Generally there are cards out there not benefiting from volt mods whatsoever... but you will definitely see gains from switching to watercooling. I wonder why your temps are this low considering all the peeps claiming overheating cards or temps in the high 80s to low 90s when pushing those cards.

BTW, there were infos from the German (European) Subsidiary that all (most?!) of the vanilla cards should be already factory-modded to 1.2Vgpu... Wonder if this is the truth.

No, I didn't measure the voltage before and after, but I'm 100% certain I did it correctly as I've got an extensive electronics bakground.

Well, I can't speak for anyone else, but as I stated earlier in this thread, if I leave my fan set to auto, the GPU temps will rise to 85-86c before the fan reaches full speed in an attempt to bring temps back down but usually once they've reached that high, the stock cooler is only able to bring temps back down to 82-83c as I believe it's programmed to run as slow as possible without exceeding 85c so it's quite possible the fan isn't even reaching 100%. However, if I set the fan speed manually to 100% before I start a 3D app, temps never exceed low 60's in most games and apps, and will only reach 73c in Crysis.

I'm sure I'll gain a little OC room from the watercooling alone, but I'm just questioning whether these volt mods have any actual affect on these cards, with or without watercooling.

your welcome

the response was towards Blkout

i got no control how you guys mod and all.. thats one.. mobo/psu is a big factor when it comes gpu vcore.. for ex. my giga ep45 extreme on which im testing the 285s.. the diff betweeen the default q9650s 3ghz and 4.5ghz oc is about .03 gpu vcore increase @ 4.5ghz.. the mobo ramps up the voltages all the voltages

psu v12 rail is also a factor

we are not all gonna get matching voltage some more some less

look man i dont need/want anyone to scream fantastic.. if it works for someone (MisterMagoo) great if it does not im sorry.. its out of my control.. only so much i can do/offer

if someone/anyone.. you want to scream no gain no problem just make sure your sure on that.. looks like your not..

if you got "extensive electronics bakground" then i should be applying your vmods to my 285

come on.. we need 1.4vcore+

~1.5 would be nice

[Blkout]

Sorry to offend. From here on, I won't post in this thread and I'll keep all mod and cooling results to myself. If everyone does the same, maybe we'll all learn nothing from each other. So much for constructive criticsm.

[dengyong]

NapalmV5....there are many here who appreciate your efforts, please continue.
