Radeon 9200 volt mod! *pics inside*

[TMM]

ok heres how you do it

We saw turbo do it, but his card is butchered version, and has a differnt power circuit to two 9200's i tested my version of the mod on

My card is a Powercolor Radeon 9200TD (256mb).

Warning, volt mods are dangerous, proceed with caution.

ok, firstly, cheers to BigZ for helping me work this out.

Here is the top of the card, the circled area is where we are working (ignore the blue arrow to the chip on the top right, its irrelevent )


Then solder two legs of a female fan plug, to this chip (the blue highlighted legs )


Now here is the back of the card, the circled area is where we are going to work next. (ignore the blue arrow pointing at a chip, its irrelevant)


Now plug in the card and boot up, locate these two points on the card. measure accross them with a DMM, you should get 1.6v~


Power down. now place a 20k resister in the fan header you soldered on. boot up again and measure. you should have about .03v more.

heres what i got:
no resistor = 1.63v
20k = 1.66v
10k = 1.71v
5k = 1.8v

you may get problems over 1.8v, becuase you will be pushing the limits of the power circuit on your card.

with no mods, i could only get 315mhz core, now with 1.8v on the core, i can run 3dmark2k1 at 360mhz core.

happy modding

very very cool! what speeds can you get artifact-free using ATITool at stock and modded volts?

[CanadianBronco]

Gr8 job!


I noticed were are accumulating a few V modder around here now thats great!

at stock voltage (and stock cooler), ati tool maxes it at 290core/460mem.
I can bench without artifacts at 315/460 on 3dmark2k1

now with the core at 1.8v, and Zalman ZM80C cooling, ati tool maxes it at 340core/460mem.
I can bench without artifacts at 360/460 on 3dmark2k1


i was going to find out the memory mod too, but i can't be stuffed anymore since im getting a 9800pro in a few days, lol.

sounds very nice to me! HOOAH!

thanks.. just what I was looking for. Anyone who know how to remove that heatsink... It's glued or something

[CaTalyst.X]

Heat it up with a hairdryer and pull it off. If that doesnt work throw it in the freezer for a few hours, thats how i got ma 9700P Stock sink off. GL!

yep i had that 9200, gone now (9800 pro) but heat it up with a hair dryer till it is hot to the touch and the get a flat head screwdriver and wiggle is fron side to side pops off in bout 10 seconds then but the evil part it getting the thermal pad off

[CaTalyst.X]

Its easy getting the thermal pad off. Just cover the core in hot glue, then peel it off. Do that about 6 times and ur good to go.

ok, thanks. anyone who know how to do a mem voltmod on a 9200 card?

[CaTalyst.X]

The memory cannot be modded as it is not controlled by a regulator, but rather by a series of resistors. Sry bro :P

[Master_PH]

ok, thanks anyway

[Master_PH]

Hi, i did the voltmod just 1hour ago and it works perfectly

[CaTalyst.X]

Cool bro, glad to hear you did it yourself! .........And that it works :P

[Master_PH]

can you change the vcore while running your pc without hurting your card?

[CaTalyst.X]

Yes. WHEE 10char
