View Full Version : anybody seen a mod guide for the nvidia 6800go?
I've spent hours looking on google (maybe I'm not using the right keywords)
my card (which is a mobile card for my laptop) dosen't want to go any higher than 385mhz without artifacting horribly and I need just a little bit more voltage to bump it up a bit more so I can obtain 5000 3d 05 marks.
I really don't wan't to try and figure it out on my own cauze I usually have bad luck when I do things like that and we are talking about a $300 card here... I just don't want to be poking around and fry the darn thing just trying to figure out how to do it :( plus there's the little problem with poking around looking for voltages when the heat spreader covers up the entire card.
obviously i'm a little inexperience at voltmodding but I think I got a nuff experience in electronics to pull it off. i've allready skimmed the vmodding stickies... now I gotta go back and read em throughly.

i did a little google search and came up empty handed. i dont see much that would help, although it is pretty sweet you're trying it. I dunno where you could find one, if anyone else has even done it.
uhmmmm normally laptop components run burning hot, i highly recomend you stop thinking about volt modding one right this instant

I have that card and it actually runs pretty cool. Usually around low 40sC at idle and low 60sC under load. That's overclocked 70+mhz on the core, and almost 200mhz on the memory. This is with the stock thermal pad too.
You can use a program called I9KfanGUI to run your gpu fan 100% while playing games if heat is a problem.

Wonder if some of those bios tweaks work the same as they do on the regular 6800 series.

you can always upgrade cooling, thats part of the OCing process. you wouldnt vmod a card in your pc with stock cooling would ya? unless of course it is low power low heat output stuff that comes with higher quality cooling componnts caus its in a restrictive environment to begin with.

Yeah the common thing is to replace the pad with AS5, you can't really do much better than the heatpipe cooler on the notebook that it comes with though. Well, making it fit in the case anyway.
I allready got the cooling taken care of... It's really interesting to see that everybody always freaks out about laptop overclocking yet my laptop runs cooler and faster than most desktop systems... I kinda know what I'm getting into...
If I manage to vmod the card in some way I am going to buy the 6800 ultra heatsink which has 2 heatpipes instead of 1...
so...
anybody heard or seen anything?
I'm starting to turn my attention toward the 7800 GT GO as it would be compatable with my laptop with some very heavy modding...
i would have to...
Get the 130w power brick for my lappie
get a 7800 GT go
get the inspiron XPS 2 northbridge heatsync (the 9300 heatsync is in the way of the heatpipe)
file the palmrest on the bottom to make way for addational heatpipe
Flash my bios the xps170 bios (currently impossible due to dell flash util checks which lappy you have but somebody on notebook forums claims to have cracked it)
flash the graphics card bios to allow overclocking.
it's just a little bit of work for no gaurentee of sucuess huh...

you can do tons to improve lappy cooling, if you have the money and drive. can have custom heatpipes made, and cn mill up some nice sexay copper heatsinks. could even have a copper plate made to replace the aluminum in a stock lappy. I've thought about making a whole bottom plastic replica in aluminum or copper, that would be awesome, but i dont think i can find any stock that big. and then it would be some massive milling, probably just do it on CNC, so i can run the prog and watch, instead of sittin there for 12 hours turnin knobs. if i could find stock for a reasonable price, i think it would be great bling factor for my lappy.
or you could do like i did on my old compaq, cut through the plastic to make room for an active HSF, i had a vantec copper vid card cooler in mine cooling the chipset. just had to have its feet up all the time, so it would get air.
goin really hardcore could be.... raise the hinges on it, make a raised latch thing, and raise the KB a little to get air through and have heatsink fins in there. can do a whole lot if you're creative :-D
alot of them are a little extreme tho.
I just found a way to mod the bios to give the extra voltages I need to hit 5000 3dmarks... if my mod fails and I kill the card then I will mod a 7800 go into my lappie and if that fails then I'm screwed...
the mod has failed but i did not kill the card... The card dosent respond to extra voltage at all... the card has been returned to normal voltage and my dreams of 5000 05 marks have been shattered... *sniff*
