X800-X850 AGP/PCIx POSSIBLE EXTRA PIPE UNLOCKING

[dolf]

Owners of "not-modable" X800 and X850 cards AGP and PCIx I believe that Xmas has come for all of us. I consider that ATI's secret was solved (from me ).
W1zzard you say "no sir" when I proposed to get out of the box and to search for something simple.

The solution could be genius and meanwhile very simple but the simple things are not always genius.
I hope that you were not right saiyng that. Yes the solution is simple "like bean" and now I am 99.9% sure that I know how to do it

My suspicion about very sophisticated core protection gave a proof (laser cut is protection but the reason for doing this is different than just protection, all cores are the same after production and before testing and marking ). The transformation takes place later on but only with lase cut (one or two).

The problem with extra pipe unlocking on all "not modable" cards could be solved easy. Other issue is how the unlocked pipes will perform. But the second good thing is that the modification is 100% convertible. Every pipe squad (4 pipes) could be shut out at any time.

It becomes too late and I am going to sleep. Tomorrow I will explane how the mod can be done with examples and pictures.

Good night

This'll be interesting !




































Or not !

Very funny, if there isn't interest on my modest resurch of how to unlock the extra pipes on R420...........R480 cores I can keep the results for me . But I don't even have such "locked" card . Why am I loosing my time with this

[mizio57]

is very interesting

[W1zzard]

i'm listening to your ideas. trust me, people are interested. if you dont want to discuss this in public: w1zzard@techpowerup.com

[Don__1]

Of course we are interested.
It's just that we are so interested that we actually want to see how to do it as we don't know.
So, how do you do it ?

I can't wait until you tell us ur secret!! I'm almost desperated with my non-unlockable Sapphire X800Pro non-VIVO (GC20-memory). I've flashed a whole bunch of BIOSes, all without success.
I've used conductive pen to close the lasercut-separated "pins" on the die.
My GPU is a newer one:
215RAACGA12F
GG0967.1
0502AA

I'm very anxious to hear from your good news, Dolf.

Ok fresko you will be the first and also the honor will be for you. I presume that you have R420 X800PRO Non VIVO with 2.0ns ram. Don't worry it will "reveal" his pipes, trust me . But there are no guarantee that pipes will work properly and you have to be ready for that.
It will be necessary to connect the laser cut but not only. I will attach picture and you have to find out the place on the back of the card's PCB. It will be necessary to unsolder / solder very small resistor. If you can't do it find somebody who can.

Today I have sent all the materials (results of my study) concerning pipes to w1zzard and hope that he can prepare some modding guide soon.

Now you have everything needed.

Success and don't forget to post feedback.

i replied to your email dolf, but no reply from you so far

Yes this iwll be intersting to see, but its a shame it won't help me cause my pipes are defective lol.
