two more questions: how is the 9800 mobility based on an x800 core... wasn't the 9800 mobility released first? also, does anyone have more results than what is listed on this thread?
Personal opinion, you won't frie your card unless it has the week specifided above 0446AA. Now i suggest you DO NOT try with a week 46 card, and i wouldnt bother with a 40 week or above, but it is still worth a try if your were as desperate as me to get the best from your GPU.
Well the MR9800 is based on the x800 core because ati had excess x800 in stock. Thus all they did take the x800 GPU core which is located under the heatsink of the GPU and make the most tiny laser cut on the chip. What did this cut do? All it does is change the no. of pixel pipelines (which does the job of producing the pixel you see on your monitor screen) and as a result decreased framerates.
To make it easier for you, imagine a circuit. You have the power supply and you have 2 light bulbs (go back to your school days). Now they r in parralel so if 1 bulb is off, the other will still be on (as long as the power supply is still active
). By connect the wire on the secondary circuit to the second bulb you have 2 bulbs active and they will both run at the same brightness just as it would be if the 1 light bulb only. So in essence, you get twice the light output.
Put this into context with the GPU and you re-connect where the cut was made, and 'hey-pressto' its like getting 2 light source - you'll be getting more graphics (in terms of FPS and pixel).
Now if you do go ahead with this i suggest you read up on the top post of this thread and check what week your card was. I have a week 21 and i went form 8 pixels to 16 pixels. i also got lucky and i doubled by shader pixels (they so exactly as stated - shade the individual pixels you see on your screen :P).
So what improvements did i see? well here are some results:
mobility 9700 -> 1798 (poor)
Mobility 9800 (8 pixels...etc) -> 3950 (not too bad)
Mobility 9800 hardmod (16 pixels...etc) -> 5150 (ok)
Counter-strike source graphics videotest (1280 x 1024) + (everything on highest nad maxed out except aa = trilionar and AF=0)
9700 -> 27fps
9800 (8) -> 73/74 fps
9800 (16) -> 95/96 fps
Quake 4 single player on highest settings (1280 x 1024) + (highest graphics levels, all advances to highest) = (sick graphics).
9700 -> absoloutly unplayable!!!
9800 -> pretty darn stuttery
9800 (16) -> Hey! this is pretty damn smooth!! holy Cra* lets use some AA and AF cos i can boost this thing!!!!
So as u can see. this hardmod rocks!!!
If you do go ahead with this i suggest u get all the equipents you need and really get to grips with the process of making this work (i.e. read this thread over 100 times and make a print out too). Ensure you know your laptop and how to open it without damaging it!!! go to dell and get their instalation tip guide. it will show you to open your laptop safely and it is actually really easy to follow. You cant really screw up (unless your a women
Good luck and if you need anything else, give me a shout!!!
