And they also come with a higher base voltage in comparison to the vanilla models using the same mods.Quote:

I started a new thread in the right section so the mods are easily accessible.
http://www.xtremesystems.org/forums/...d.php?t=220607
I will update that thread with the OCP as soon as I have fixed the image.
So, guys, yesterday I decided to put an end in a too-long-lasting process of stability searching. I added for testing Fur Bench and 06 3d mark. And, of couse, Warhead bench (for I still haven't installed original Crysis yet). The problem was: marks are running well, without mistakes, Warhead bench looped makes successfully about 30 cycles. But when starting running Warhead the game, crashes may happen in 1-2 hours: black screen and reboot.
I started with 756/1566/2916: fur bench forced system to reboot in 5 minutes; I set GPU 1 step lower - to 740, while shader domain and RAM were left without changes - successfully ran 30 minutes. Beign curious, I set Warhead-unstable value of shader - to 1584, and started furmark again - 10 minutes with no mistakes, after that a turn it off and switched to 3d mark 06. The frequencuies were 740/1584/2916; Fireflies forest ang Canyon flight looped to 15+15 cycles. Fireflies flew splendid, while flying ship droped system to reboot on the 13th run... After I set 740/1566/2916, Canyon flight ran 30 times with no mistakes.
So, hope, these are the final clock-values to my vanilla. Unfortunately, my sample appeared to be too poor overclocker :(
All hopes-only for Vmods
those of you hitting solid colors/other anomalities with my vmods..
check crotales ocp mod.. may be fix for
im hitting solid colors even on my unmodded ftw when pushed too far/great loads
i just 22ked my unmodded ftws ocp and as ive suspected.. ocp is a real mofo on the 285s especially @ air/even water.. though doesnt show its colors easy @ subzero temps
so whatever vgpu mod you guys go with.. several to go with.. if youre on air/water ocp mod is a must
thanks goes to crotale for the ocp mod
time to crank up vgpu
if you guys want higher mem.. ocp mod will take care of that too
ive gained 100mhz mem @ heavy load
you want lower temps? ocp mod will do that too
ive never been able to clock my ftw @ 1512 which would cause blank/black screens
here i am @ 1548 mem clock @ heavy load thanks to the ocp mod
overall 150+mhz mem gain @ heavy load @ stock air cooler
once again thanks crotale for the mod :toast:
Nice progress NapalmV5, keep pushing it!Quote:

So, if I make OCP mod it will fix the problem in step #3 with 150 ohm VR, because when I did it for 1.28v it was impossible to bench with my old settings (black screens) before step #3 and I've removed 150ohm vr.Quote:

Also Vantage, Win7 x64, @783/1800/1512 - 1.24 vcore http://img243.imageshack.us/img243/6...8001512oc2.jpg
GPU is under water with MCW60 and RAM sinks with 120mm fan.
Also if I make the mods of crotale, have I to remove your mods step #1 and #2?
What is the ultimate game/app for stability testing ( Furmark not included )
today ill do just that on the ssc + amp.. vgpu + ocpQuote:

step 2 not necessary and only do it if you can/want to replace the vdiff resistor.. pencil is very unstable
at the moment i do not know how any of the steps affects crotales vgpu mod
if you dont want to find out.. go straight to crotales mod
every game/bench has its own load.. best to load up your fav game and see how long it sustains your ocQuote:

ocp mod lowered temps by at least 5 C
With those clocks will the fan speed eventually ramp to 100% if left at auto ?Quote:

I'll try that out later as soon as I know what's stable for my CPU/RAM. Too bad I'd have to take out the card again (that means to remove the waterblock... dayum).
Im getting a graphical glitch in crysis warhead, its like the textures are all warped and garbled.. memory too high ?
http://img7.imageshack.us/img7/4083/glitchx.th.jpg
From my own testing this happens on this map ( the map where you need to goto a submarine ) and only i im doing alt-tabbing, and it fixes it self by moving the view around.
it could or your card is your heating or driver issueQuote:

Shifting to the most interesting - the results:
VGpu:
before: idle - 1.055v; Warhead benchmark - 1.166-1.168; Furmark - 1.168-1.170
after: idle - 1.068v; Warhead - 1.233-1.234; Furmark - 1.235-1.236
Vmem:
no changes: idle - 2.10; Warhead - 2.12-2.13; Furmark - 2.13-2.14
Clocks:
before: 740/1566/2916
after: 756/1674/2916
Shader domain appeared to be the most voltage-hungry. Current clocks please me much better, than vanilla.
Thanx, Napalm.
PS temperatures: +2/3 Celsius in Warhead; +6 in Furmark
I gained NOTHING from the OCP mod... memory, core or shader... I lowered the resistance to 15K... Do i need to lower further?
oh you`re not the only one my friend...
^ may i suggest fixed resistor @ ocp mod? ;) (10k resistor)
core/shader not so much but mem is the one mostly/greatly affected by the ocp mod
@ inzer890 your welcome :toast:
I tuned down to 11K and it was the same... I removed the OCP mod and did the vGPU mod and i'm getting GOOD results!!! Thank's crotale!!! :)Quote:

1 (maybe silly) question... If later on i want to sell my card do i need to solder again the resistor from the vGPU mod?
no just follow/do step 1 of my vmod guide
Why? The card don't work without the resistor?Quote:

Thanks! :) After all i am getting GREAT results from the OCP mod... In 3DMark 06 i was getting instant black screens with my current clocks 756c/1692s/1404m... Now they are GONE! :clap:Quote:

Im glad this tread still here , its a whole lot of great info found here and nowhere else ,keep up the good work guys.
chispy.
Hey guys, I have done The vGPU and OCP mods and I am getting great results (837core, 1836shader, 1404mem - benching. 826core, 1836shader, 1377mem - gaming). The question I have is this. With the OCP mod I used a 225K ohm VR and tuned it down to 100K ohm, I then tuned the VR down to 75Kohm and everything seems to be fine. Now I see you guys talking about 18K ohm and 15 K ohm, are you talking about the VR or the SMR your effecting on the board. It's just that if I can reduce my temps and maybe get a little more MHz out of my memory (like has been reported) it would be nice(my cards memory clocks like :banana::banana::banana::banana: compared to other 285's), I just don't want to fry my card. Just so you know my card reads 1.36v vGPU under load and it's water cooled. Thanks.
I was wondering if anyone knows if the Palit GTX285 2GB PCB is based on the nvidia reference design? I am thinking of getting one, modding and using a full-face waterblock, but if their custom PWM-fan heatsink design differs from Nvidia's reference holes, that that would be a problem with aftermarket cooling. Can anyone enlighten me?
http://www.techpowerup.com/86189/Pal...GB_Memory.html
Pretty interesting,i like it.
As soon as my new resistors arrive i 'll try some of the these mods....
It uses an accelero xtreme gtx280 cooler, it has the same mountingholes as the reference gtx285Quote:

Quick question.....is there a voltage difference between the vanilla GTX 285 and the SC edition? SC is actually cheaper right now @ the Egg, eVGA at least.
~Ibrahim~
No difference.Quote:

So, in your opinion, if I didn't mod the voltage myself: is $25 worth going from Superclocked to FTW, identical bundle, etc.? SC is clocked at 675/1548/2538 and FTW is 702/1584/2646.
I'm sure the SC can reach FTW speeds, but can the FTW reach even higher speeds? It's all guesswork, I know, I'm just wondering what you guys think I should do.
~Ibrahim~
Hallo everybody, I'm new here...
I made vmod N°1 (3 bridges) on my vanilla; now I can reach FTW clocks on my Asus, but memories give artifacts as temperature raises (at about 80° with stock cooler and 100% fan). Another question: if FTW differs just for jumpers, why can't get same voltages with modding?
Thank you everybody!
Just buy a vanilla GTX 285 , OC it with no v.mods , you will reach FTW speeds in no time most likely. The same vanilla can be v.moded with this simple mods posted here and it will anihilite the FTW overclocks ;) , save your money and get a vanilla , my best overclocker its a vanilla eVGA GTX 285 it does 904core 1800shaders and 1410memory on LN2 on 1.26v , on stock cooling it is stable up until 785/1684/1410 on water 810/1704/1410 , its your call and your desision.Quote:

Nice...
Well, I'll be honest, I'm probably not taking it any further than the stock cooling, lol and I'm too much of a pansy to kill eVGA's beautiful warranty to volt-mod it. Decisions, decisions.
Thanks for the opinions, though. I think I'll go for the SC, though. I'll OC the crap out of it and I have 4x120's in the side of the case; hopefully, some of it will help! :DThanks, again!
~Ibrahim~
nice tip... having 50 mhz more
Hello,
I just purchased the Gainward GTX 275 card, whose layout looks exactly like the bigger brother GTX285 in this shot:
http://xtreview.com/addcomment-id-80...e-GTX-285.html
The card uses a RT8841 chip on the front side, next to the digital audio input.
Any solder mods for this card type, or other overvolting solutions?
The chip is actually one for controlling the voltage of AMD and Intel CPUs, using Voltage ID pins...
http://ceemic.pri.ee/hardware/datasheets/RT8841.pdf
Very nice.Quote:

If you want to learn to volt mod, you could try picking up an old 7600GT/8600GT off Ebay, and try volt modding that via one of the guides here, or the guides over on Techpowerup's volt mod section.
Of course, feel free to post some more questions for us.
Ah right. I was wondering how a multi meter actually measures resistance. Does it run a current through it?
Where is the point to solder besides ground? I cannot see well in your explanation. Thanks.Quote:

@NapalmV5 and Cryptik , maybe you guys can help me , i killed one of my GTX 285 in the middle of an LN2 session , it was an eVGA vanilla with the bridging mods and 1.26v. I bought another eVGA Vanilla for replacement for my tri-sli runs and to try again go tri-sli under LN2 again BUT the new eVGA GTX 285 i received have a different PCB and i cannot find where they have move the bridges for this quick mod as its totally different PCB as my other 2 cards :shrug: , anyone have a volt mod for this new PCB of the GTX 285 eVGA brand ? If pictures needed let me know and i will post high resolution pics of this new PCB so we can work something out , it will be greatly appreciated any help on this matter :up:.
Angelo.
evga? 1gb? hmm.. yeh post pics.. is it similar to the 2gb pcb?
eVGA 1GB , i dont have any idea what the 2GB model PCB looks like :( sorry.
I will post pics asap :).
Thanks bro.

Any info on volt mod on this PCB bro ?Quote:

Step one I hit 1.26-28 depending on what im running for a load test, these cards out of the box were at 1.20 under load with furmark so they seemed a little higher from the factory. My 3rd 285 is a non reference EVGA 1gig and its only 1.16-18 load on the old fluke dmm. Anyways on my water chiller setup I was able to get my loads at 23-26celcius alowing 775 core and 3000mhz ram speeds. With added voltage my shaders now are able to run at 1650-1700+ instead of vanilla 1571mhz my temps are exactly the same also before volt mods and after.
102,302 on 3dmark03 with upper mods :D
Step 2 with pencil trick,
I shaded the resister down to 340 ohms on both cards, a mechanical does not work, find an old school pencil 2b. This worked beautiful for voltage at 1.312 on both cards exactly but when I tried to run any heavy overclock I hit OVP. I definitly could see a huge improvment in overclock after shading in though since the cards could run at 800+ but at certain points in 3dmark03 it would kick in OVP. I also tried to run my overclock on them that was 100% stable with only step 1 of the guides at 775core/1500ram and it would OVP on that also. Crotale and Napalm were saying in other voltage mod thread that even stock/water pushed hard will do it cause of unstable current while on the ln2 and dice they are more stable current from being froze. I cleaned off my pencil trace's and retested at step 1 mods 1.26-28 and regained my stability at 775mhz no OVP. When I get bored ill do OVP mod and rest of voltage mods, this along with water chiller and mcw60 blocks have made a awesome gamer/3dmark machine thanks Napalm and crotale!!!!!!!!!!!!
Also chispy
I have that exact card as you and ended up with one of the non reference evga 1gig 285 vanilla. Ive tried looking and comparing circuit layout but its not even the same as my other two. Just wanted you to know my BFG and my XFX vanilla's are old style revision if you want to get a matched set for your two.
So can I just double check... The right way to do this is to use silver conductive pen on 1/2/3/4 11/12 right?
And then 2b pencil on the other little resistor?
I don't wanna do any hard modding... Just the reversible ones for me :)
How do you measure what voltage you end up with? :)
Hi,
I am looking at buying a GTX 285 shortly, I noticed that EVGA appear to have updated their cards using a different PCB and memory (.7ns against 08ns IIRC). I have found a couple of different part numbers, would anyone know or can anyone confirm if these cards would be compatible with this modification?
01G-P3-1180-AR - Vanilla
01G-P3-1181-AR - SCC
After looking at the sticker on the back of chispy's card I am lead to believe that these two may not be compatible? I don't know the 'older' model numbers of the cards that have been modded...
Any help would be great - even if its a different brand such as Asus / XFX / BFG
Thanks
Yes they are compatible :yepp: , i had gone tru many GTX 285 (eVGA vanillas,BFG OC+,XFX XXX and all of them were compatible , even my new different PCB eVGA Vanilla plays well with my older cards , so it will work , no doubt about that. Good Luck.Quote:

Just wanted to say thanks to napalm, and the others who added their input, for the vmod guide. I got my gtx285 up to 775-1700-3000 as compared to a previous 725-1651-2950.
New problem has arisen for me though. I can't get my 3dm06 score to go any higher above the 725-1651-2950 clocks. Score actually drops if I go higher than that. Any iedeas?
it's a vanilla evga card with a koolance fc block on it. q9650 at 4.25 too
Guys, has anyone found any GTX 275 Pencil/Ink mods? I have my BFG running at 1.18v and it's stuck at 738/1476/1215 - any higher on the core/shaders and it just freezes, temps are good and no artifacts...
Its just pushing it too hard for the voltage, frame rates drop giving you a lower score. Give it some more voltage if you want to run it higher.Quote:

Yeah, stock EVGA vanilla vgpu is 1.16v
ta, know I hope sergio can measure his BFG card for me...
Figured it out, mostly. I ran vantage instead of '06 and it was flawless up to 775-1765-1400 (scored a 17407). Then I ran the furry donut for an hour and it was stable. Last, I ran crysis benchmark for 50 loops on very high with 8xaa, and it was fine.Quote:

as you can see
1/3/11 are bridged the rest no, should i bridge 2 and 4 ?

Ok boys i did the mod,
vid 2 leads me to 1,2vgpu / 2,11 mem loaded so i went to vid 4 and gave me
1,23vgpu loaded / 2,11 mem
i got now 1/2/3/4/11 bridged i dont know wich increases vmem
so far i went on W7x64 on Sacuary for this and played crysis very nice clocks
couldn pump much more on CPU as i have 25,7C in my room damn hot tomorrow i will do some benches under AC

I have now a Asus 285 TOP with the uP6208AM / VGK939 voltage controller like the one on this page: http://www.syndrome-oc.net/articles....page=4&lang=en I know that pin 9 is the one to use. Anybody has a clue what pot value should I use? Many thank's.
^ just how tight is OCP @ 285/uP6208..
ocp removed/vgpu @ 1.4-1.5 and the 285s could do ~900 core on air easy
ocp is just too tight on 285.. then again i guess that was the point/purpose
285 1gb/2gb ver1.1 OCP mod :toast:
dont thank me.. thanks goes to crotale for the ver1.0 ocp mod :up:
