6800NU AGP
Compare it with the reference design.
Sorry for the bad pic, but I think you can see that the layout of the caps for example is very different.
Do you want any other pic? check www.asus.com

:banana:
i need the back of the card ;)
OK I'll get it out of my pc and put it under the scanner :D , digicam sucks.
Ohk guys i did an evga nvidia ref pcb vmods to 6800NU last night. I did the vmem/vgpu and i should have pics up pretty soon :D

Sorry for the bad quality.
I will take a look this night ;) can you give me the IC's reference on the bottom left of the board and the little one with 8 legs near the molex ?
i admit there is an other design :banana:
to get the Asus V9999GE to 494/1290 I had to watercool the videocard, and volt mod the core. thats all.Quote:

to volt mod a Asus V9999GE, just use the 6800 Ultra volt mods from VR zone.
The little 8 legged near the molex im almost 100% sure controls vgpu. If we could get whats written on that chip it woudl help us greatly :D

PFFFFF, just put the card back in and the screen just freeses when the windows logo apears artifacting like hell, did this a few times but the same all the time.
I took the card out, removed some dust and greas (from manufactoring ?) and now it work like a charm again.

Lucky me :D
If you doe the vgu mod, will that take away the stress of the mofsets and other stuff on the card ? Just upping the voltage by bios higher than 1.3v isn't a good idea because the chips to regulate the voltage and the mofsets doesn't like that on Asus 6800NU and other cards.
The most important thing for me is a vmem mod and a cap-mod for the mem, maybe a vgpu is nice too but upping the vgpu from 1.2v (1.23 in smartdoctor) to 1.3V (1.38 in smartdoctor) by bios didn't gain me much, so I think the voltage gets unstable above 1.2v also because it's overvolting at 1.3V.
I can't verify it, but ...
I think isl 6522 is used for memory voltage regulating, try to mod it by adding a VR between leg '5' and ground. Because i can't mesure anything on your board, i can't say "use a VR of XXX Ohms" but using a 100 kOhm must be sure enough ;)
to figure out where are voltages reading points and cap mod soldering points use this datasheet and try to trace back vout on your board ;)

You are correct, the vmem mod can be made by soldering a 20K VR set at max between legs 5 and 7 of ISL6522CB :) As for vGPU, the RT9202 Definately controls it. Solder a VR from leg 6 to leg 3 (GND) of RT9202, lower resistance for more volts. I will post a picture and VR values in a few minutes.

Ohk guys, just follow this pic. It has everything you need to vmod ASUS V9999 :)

BTW Del gro, not to step on any toes here, and u did a GREAT job diagraming these pics, but there is a better solder point for vgpu. As shown in this pic:
http://img48.exs.cx/img48/103/5badeu...91220235pp.jpg
That point is connected to an SMT resistor on the board. The pad pointed out in your diagram is hard to tin and solder to for n00bs compared to an SMT w/ solder already on it. Just pointing out an alternate solder point :P

thats nothing like modding a Asus V9999GE, unless they drastically changed recently.Quote:

the mods are exactly like a 6800 Ultras.
these look like a 6800 NU.
Sry i screwed up the model #

you think it's hard to done soldering job for vgpu ? cause i admit it for vmem ( the soldering area is really really really really small ) but it's an hole for vGPU so i was thinking it was easy to achieveQuote:

Maybe this mod can be placed in the 6800 vmod thread in the startpost :)
If I post a pic of the caps layout can you show me how to do the capmod for the mem and gpu?
I'm really a n00b in electronics and I don't wanna screw up anything :p:
i think it will be really difficult for caps : /
if you can have a really nice pic of your board, there isn't any problem to put it at the beginning of the thread, but actually .. it's not really clean :lol: try to found a a digicam ;)
Ok I will, but would a few random placed caps help any?
Maybe between the point for vmodding also put some caps?
There are so many people waiting for the Asus vmod, I'll ask to place this pic in the topicstart of the thread untill I have a better picture.
the caps must be placed between Gnd and vout, not vmodding points
Gnd = ?
vout = the point where the core and memvoltage is 100% converted, right?
I'm a n00b, please be kind to me :D
i will be evil with you !! :D lol
Gnd is ground, and vout is where you can mesure 'true' voltage for GPU or memory, this is why voltage reading point can be capacitor's legs ... but sometime, other spots to read voltages are preferred ;)
Ok thanks but what should be the point to solder the ground ?, this is my last question.
this is my preferred gnd point, cause it is easy to solder on them :
