Yes, get yourself a multimeter.Quote:

very good
what type of cap must i buy?
VR 100k is it a trimmer or a simple resistance?
VR = Variable resistor, trimmer, potentiometer.Quote:

i hope.:D
i must buy a molex sò i make a point of scanning for a tester!:)
Today, i buy a simple resistence to 100kohm.
But i don't find the caps:(
The resistor is a trimmer right?
Don't worry about the caps. It's more of a finesse mod.
no, resistor is not a trimmer but a simple resistor.

Well, a trimmer would have given you the precision to adjust the voltage on the fly. Adding the 100K resistor should give ~.05v increase from currant VID.
BTW, from my personal experience 100K trimmer works better for vMEM the the 200K. If you will check, the 200K trimmer will be tuned well below 100K to get vMEM above 2.0v
WOW, that's a lot of glue. :D
Whoa... :eek: Did you sneeze on the PCB by accident..?! :D
ok,Quote:

On memory there is a trimmer, when i have a tester, i change from 200 to 100!
I know that the simple resistence is fixed, so i have always 0.5+, but i can change vid by switch dip (from 1.20 to 1.50). I can have maximum of 1.55 right?
maybe i have find the caps, i destroy girlfriend's motherboard!!!:D
one question.
must i use tester when vga is on! or when vga is off?
good, i destoy a motherboard.
Now i find some type of caps:
6.3v 1500uF
6.3v 820uF
16v 1000uF
6.3 330uF
6.3 680uF
http://www.justoverclock.net/out.php/i5836_0001185.JPG
and
a red and grey caps with2.5v 551 821
http://www.justoverclock.net/out.php/i5837_0001184.JPG
what caps is right?
The 6.3v 820uF caps should do nicely.
You need to test card's voltage while the card is operating.
very good!!!!!
at thusday to monday i will stay to university. When i will come back, i finish the mod! e i do some extreme bech with SS!:D
one problem
How should I position the condensing
there's one place in particular? and how can I put it?
points are circled in red free
http://www.justoverclock.net/out.php/i5838_img.jpg
the last one
on the cap there is a gray strips are gray, this side is the ground, right?
You just need to put a cap or 2x on those GPUv points...I like to set them at an angle, and solder them in.. and yes, the side with the stripe is ground. Here is a better pic of some caps installed on a 4850...
http://i265.photobucket.com/albums/i...s/P1050880.jpg
Here's another pics of my caps. Again, I really like your switch for adjusting VID on the fly. Very nice.
http://i170.photobucket.com/albums/u...l/100_1234.jpg
ok
i put 2 caps in the 2 red circle of last my photo!
but there is only one different,
i find normal electrolytic caps:(, this 6.3v 820uF
http://www.justoverclock.net/out.php/t5856_0001187.JPG
you use only solid caps!
is there many different?
now i have only one type of solid cap, but it is 2.5V 551 821
http://www.justoverclock.net/out.php/t5855_0001188.JPG
Use the 2.5v caps :up:
I have swapped out caps a few times on my 8800GS...and havent been able to tell if some work better than others or not. Testing with max vcore and clocks though, yield another 30-50mhz for me with caps of any kind on my 2x output phases for GPUv...I think the 2.5v caps will work good as well.
@ Pizza- thought I'd come hang out on your thread over here :p
ok boys!
the red caps are on pcb motherboard, there is a way to remove?
Touch your iron to the points underneath the board to free the caps.
I use a mini-torch to get 'em out...the OEM solder is sometimes pretty hard to heat up...either way will work though.
Yes, the VR mod will give you greater precision on the amount of voltage you are giving the card. Sorry for the late response. How is your mod going?
Here's some update from those with other PCB designs.
Zotac VR mod points
Galaxy VR mod points
XFX VR mod confirmation coming soon.
@ Pizza..if the XFX9600GT uses the same IC controller as the 8800's...I have confirmed the mod. ID# on the IC is something like 'B9NJ' 'er something of this nature..dont have it in front of me atm..
Hi guys, I'm about to start my journey into a voltmod. I have full access to all the proper tools, and all the parts required. And a 4 probe digital oscilloscope. I'm learning electronics at my college and so we have a full blown lab with everything needed to do basic electronics and a little more.
This will be my first computer hardware voltage mod.
Anyone have some experience with BFG ?

I posted some pics, cause' I see everyone else doing this. I'm going to ask the experts if I need to take some better more zoomed in pics so they can double check where I need to do the volt mods too. Also, I took off the heatsink and applied some arctic silver ceramic instead of the default material. The etching on the ram surface was difficult to read but it's the 'better' samsung ram.
Currently I'm running 704/1773/1087 core/shader/mem with no artifacts in atitool. I also noticed that this is what they call the 'reference card' I should have no problems as there is lots of info about doing the mods.
With ref design you are going to have to do a VID mod.
Measure points:
http://www.techpowerup.com/articles/..._back_1024.jpg
I used the VID mod info from here:
reference designhttp://www.ur-hardware.com/guide/17-...20-9600gt-vmod
http://xtreview.com/addcomment-id-49...-volt-mod.html
Stock 1.15v VID (the two links above say that stock is 1.1v, but I've yet to see a 9600GT with 1.1v. All have been 1.15v.
http://i170.photobucket.com/albums/u...l/100_1222.jpg
The 1.30V VID worked great for me on air.
http://i170.photobucket.com/albums/u...l/100_1147.jpg
If you need help figuring out which VIDs to connect or disconnect to get your desired VID, just ask and I will be glad to help.
I also added a VR so I could tune the voltage as needed.

Hope this helps a little. Also, BFG uses Hynix memory chips on this card. Don't even bother to mod them has they will die a quick death.
~Pizza
thanks for your reply; PizzaMan I really appreciate it. Regarding the memory, I read on the DDR3 chip surface that they were manufactured by SAMSUNG. Does this still matter ?
Nice you got lucky. The BFG card I got was Hynix. You can run the Samsung at 2.1-2.2v.Quote:

You can use this pad with a 100K VR:
http://www.xtremesystems.org/forums/...4&d=1204010755
VR ajusted ~90k ohms will get you 2.2v
If you find that pad hard to hit with the tall resistor next to it you can use this other point labeled in this link or pencil the resistor next to it. http://www.ur-hardware.com/guide/17-...20-9600gt-vmod
I greet there is ready vMod vGpu and vMem?
It is possible for it fasten potentiometers boost and tension?

I apologize for my english.
As it is not perfect.
I like how you attached the potentiometers!Quote:

http://www.ur-hardware.com/guide/har...mod-guide.html
Employ potentiometers?
What about resistances?
Do these values will be good ?
100kΩ for vGPU between the marked point and ground.
200kΩ for vMEM between the marked point and ground.
I will achieve that tension.
Yes, those values will work.Quote:

What only 1.2v?
Make it Had that mum that in order to 1.6v?
It tension not gay cheerful 1.2v.
Do the VID mod and you can get past OCP.
http://xtreview.com/addcomment-id-49...-volt-mod.html
Will suffice they for me 1.45v?Quote:

This opinion sentence thinks too
Quote:
Increase in vcore voltage over 1.4 v, do not improve the clock frequencies.
Anything over 1.35v will depend greatly on cooling.
I have cooling SS.
So, there will not be with cooling problem.
I thank for assistance it very PizzaMan.
Can it be included at it v-mod OVP?
http://xtreview.com/addcomment-id-49...-volt-mod.html
As at tension during 1.3v 3DMArk06 and it falls on below tense me 830Mhz GPU 1v, and it does not start test.
Happens what?
Which VID voltage are you using? IF OCP is tripping and core voltage is defaulting to 1v then you need to use a higher VID.
I have made 1.3v.
There is at ok 820Mhz on GPU.
As it on during beginning of test put tension fall 830Mhz 1.0v.
What is there?
It walks about test here 3DMark06.
You are tripping OCP. Raise the VID to 1.35v and you should be able to push a little higher.
I use I it only v-moda http://xtreview.com/addcomment-id-49...-volt-mod.html
Unused with v-mod potentiometer.
What walks it so, about?
The potentiometer is not needed, but you can increase a little bit over VID voltage with it.
But it can employ potentiometer will be it and then, tension?
Because it falls on at over tension 830Mhz GPU 3DMark06.
And at 1.2v and there is just 1.3v.
Try the 1.35 or 1.4v VID.
Sorry if my answers aren't what you're looking for. I don't really understand what you are asking.
Is what for graphics v-mod Zotac?

small update, i broke my BFG9600GTOC pulled off a solder pad. yep, don't do soldering without your miniature-soldering kit kids. And also don't yank the wires to check if they are on tight after soldering. (LOL )
I've been searching all over for a vMem mod for this card. It's a Palit Sonic 9600GT 1GB. Here are some pictures of the card: http://postimage.org/gallery/1937g22c/ Can anyone help me? Thanks.
Is the IC in this pic the RT8802?Quote:

Hey, thanks for your help. It appears to be an "RT8105". http://postimage.org/image/xyxrf65ad/
Ok, you need to measure the resistance between FB(red) and ground(yellow). Once you know the resistance you'll need to use a VR roughly 20 times that resistance.

Thanks a lot, PizzaMan. When you're hungry or you need an electric mind and a steady, even hand, go on and call on the pizza maaaaan. :)
On another part of this thread, I saw you mention adding any solid cap. 2.5-6v with a uF rating of 800-1000, to increase stability at higher clocks. Do you know where on this board I'd need to solder those? Thanks for the slice -- of wisdom! ^ ^
Piggy back the legs of the existing caps that are on the board now. :up:
