The utimate mr9800 pipe unlocking guide

post #1 of 31
Thread Starter 
*Before you start it is VERY IMPORTANT to check the week the card was made*

1. Consult the Dell Inspiron 9100/XPS documenation on how to open your computer and remove the graphics card
http://docs.us.dell.com/support/edoc...0/sm/video.htm
2. Remove the 4 screws to take the heatskink off. (you will need a Torx 8 screwdriver)

3. On the core (the big square chip in the middle of the graphics card) there are some numbers and letters that look like 0435AA. 04 means 2004. 35 means 35th week.


If your card was made before the 40th week, you have good chances that the mod will work (but also a possibility you will fry your card). If your card was made after the 40th week the mod will probably not work and you have good chances you will fry your card (two dead cards reported).


Here are some results from a previous thread

??????? *** dead card ***

(please post a reply to add your card to the database)

NO BIOS FLASHING IS NEEDED
You can install the graphics card drivers again if you want after the mod, but I don't think it is needed.

4. Use a small flat screwdriver and scrape the two right hand dots until they are shiny
5. Join the two right hand dots with a conductive pen.(make sure the two dots are completely covered)
It should look somehing like this


6. Wait about 10 minutes for the conductive paint to harden.
7. Put the heatsink back on and assemble your laptop back together.
8. Wait about 8 hours
9. PRAY!!!
10. Turn on your computer crossing your fingers and run ati tray tools. Go to Hardware>System Information. Check how many pipes it reports.

If you want to remove the conductive paint use 99% pure acetone.(You can buy it from your local chemist)

I will personally take fully responsibility for any damage caused my these mods. And will also give you 1 Gazilion Dollars in compensation. And a top model girlfriend of your choice.

Hey guys, does it matter what kind of conductive pen I get? Will some pens conduct electrical current better than others? Is that why some mods fail and some mods don't? Thanks.

i'll create a separate thread...sorry guys =)

Hi all, Thought i'd give this mod a try and ATI Tray Tool now reports 12 active pipes. The info from the GPU: 0439AA

Runs fine, no artifacts. Running latest dell 9800 driver and i think the sticker on the video card stated that the bios was A00.

I havent overclocked the GFX yet. May do if i get the heat sorted.

However i noticed i now suffer lockups in games. I think its something to do with the extra pipes being open adding more heat.

Now the mod worked how do i fix the heat problem? Help would be great.

Regards,

Xy.

You guys are crazay! How many pipes does the MR9800 originally come with? If the performance difference is big enough I may want to try the mod.
post #16 of 31
i wonder if this mod would be more successful if an actual resister was used instead of just allowing all of the current through? none of the other bridges are resistor-less, probably a reason for that?

The 9800 comes with 8 pipes originally.

I have 2 questions

1. Like Speedyturtle was asking, how much of a performance boost is this.

2. As to be greedy, at this point is it safe to overclock a little more?

Whats the difference between the 9600 and the 9800? I have a laptop w/ a 9600... wondering if this could work as well, or if there is something similar to this.
post #19 of 31
completely different cards. the mr9600 is basically a mobil 9600xt. The mr9800 is a mobil/agp X800 with reduced pipes active. This is why the mr9800 can have this done. It's core was a 16 pipe core, with 8 pipes unconnected.

other differences would be 4pipes vs 8, 2 pixel shaders vs 4. and clock speeds, but the speeds are not relevant to comparing performance of these
