X800-X850 AGP/PCIx POSSIBLE EXTRA PIPE UNLOCKING

[ChAce]

lol but when i unzip it it doesnot have an extension ;o

edit :
tried changing it to .com and .exe but it didnt work

lol, you put it on the floppy and use dos commands to use it, your computer will understand you "little asshole"

Hi.

Ive been watching this thread closely for a week or so, and my hope is still there that we can make this work. So, I figured i could contribute a little to your research. I attatched the info ATItool gives.

I have done the following "mods" to my card.

I connected the "lasercut" with conductive paint, after that i flashed bios with various 16pipe pcie bios versions. But I didnt have any luck unlocking pipes. My x800pro vivo (built by ati) pci-e is still in 12pipe mode. At the moment my bios is the original i got with the card, and the screenie is taken with that bios installed (if that matters).

Cheers, and good work you guys do! Thumbs up!

acording to that pic it looks like you are out of luck dude :/

Klootzakje, sorry for the misunderstanding but it is clear that firewall stops all the executables I have forgot that. Download the flashrom16 from here: http://www.techpowerup.com/articles/overclocking/vidcard/100

Success

 

[klootzakje]

thanks will do it tonight again, now i'm going to work

 

[klootzakje]

here i flashed a x850 pro bios onto it and the 3e2 changed to 3e0

i also flashed a x850 xt bios onto it

but offcourse still 8 pipelines

 

[W1zzard]

yep rom fuses can be freely changed by changing the bios, but they seem to have no effect if die/substrate fuses are in effect

 

[dolf]

Klootzakje, even failed in opening the 3 quad (12 pipes) it gaves more information about the cause and way of locking. At present you can't have 12 pipes but I still have a hope and new idea but we have to be patient. It is more radical than resistor config. and I need time and info in order to prove/disprove it.

In order to have 12 pipes I presume that is necessary to obtain "f" in the last place in CONFIG_SUBSTRATE_FUSES 0xFFFFFF9D (your). It have to be 0xFFFFFFxF

For 16 pipes on SE is not reasonable to tnink but on PRO is very nice idea. To have 16 pipes it is necessary to have "F" on 5th position in CONFIG_DIE_FUSES 0xFFFF9FFF (your). It should be 0xffffFfff.
If we find how to unlock doesn't matter which quad (3 or 4) we will unlock the remaining because the mechanism of lockind is the same.

Thanks for the great job done

 

[klootzakje]

how can i/we help ? i don't mind trying hardmods or making more detailled pics, if you say which piece(s) of the card you pictures of

 

[dolf]

Guys thanks a lot in advance for the support. When the time comes I will again turn to you for help. But first I have to play with my own card and when I am ready will ask you for just measurings. I will need (I have to collect) data base to compare with. Arm yoursef with multimeter and patience because I need some time .

Powercolor x800gt tried a x800xl bios still 8 pipes

Something of interest?:

seen that post like days ago... but most x800gt's don't have the 423 core....

 

[dolf]

Shyska, could you please perform the ATITool research for fuse lock. More information you can find here: http://forums.techpowerup.com/showthread.php?t=5367 and post your results with 12 pipes.

Thanks

 

[dolf]

Fresko, unfortunately I couldn't find any diferences within the provided BIOSes. The "problem" is on the hardware level and is not so connected with the resistor configuration as I believed. But it directs me in other direction and soon i will need again your help with just measurements as a beggining. We will see is it possible to do something more in order to unlock the last quad.

In connection with the above please read time to time this thread.

 

[fresko995]

it's ok Dolf. - one other thought i had about the hard-fuseing of the pipelines: when comparing the upper-sides (surface) of all the X800-GPUs against eachother, are there any differences among those very small "resistors" there (if they are "resistors"?)? I assume the only other difference is the dots with or without the lasercut, which we all know since the beginning of modding X800Pro's.

If there aren't any important differences, then the secret of unlocking the pipelines is very likely on the PCB, as you already assumed before. but HOW did they lock the pipelines?
maybe not only by configuring some resistors but also by performing some other modifications on other areas of the PCB (front-side, back-side).

if I could set my card aside I would even lend you my X800Pro in order to find the solution for the community

 

[dolf]

Fresko, don't hurry on I will make some research on my card but it is XT and all the measurements have to be compared with PRO. Fortunately you have one laser cut which is good for comparison. When I am ready all of you will receive step by step "measuring" requirement which can show something interesting. You will be load up to conduct these measurements and to find possible differences and finally to return the information to me (I prefer to keep it private for now. That's why please provide me your mail and I will be very greatful).
Cross fingers and light up candle to find (invent) method for reverseing of the fusing if it is possible at all.

POWERCOLOR X850PRO Pics

I've attached pics of the soldered jumpers and the ATI Theatre chipset along with the front side showing the jack that indicates VIVO.

Can this Powercolor X850PRO's 12 pipes be increased to 16 pipes with ONLY a bios update, or does this card also require soldering to get the extra 4 pipes?

 

[dolf]

Run the ATITool pipe research and post your results here or/and on the http://forums.techpowerup.com/showthread.php?t=5367 and you will have your answer
You could use the link for information what and how to do.

Hi!

I have the same card as klootzakje. A Club3D X800RX (actually its a X800GT).

When I switched to Zalman cooling I made some Pics of the core:

Maybe important for a Hard Mod?

Also I did Scrennshots of AtiTool, here with original Bios (although Frequency Modded):

and here with flashed X850XT Bios (to bad only 8 Pipes, but I think thats whats all about here ):

Tell me how can I help. Im not afraid of HardModding too.

CU

 

[dolf]

Thanks for the reply. The time for R480 will come soon and every information will be important and also courage to do some hardmod. At present I will play with R420 because I have such card but it is just beggining .

 

[dolf]

Fresko Hi again,
I am ready with my "measuring request". It was difficult for me to start but for you it will be easily (max. one hour).
My X800XT is dismantled for a week already and will remain in this condition until I receive your results.

Please inform me when you have that and if you have questions .

 

[MeridiusZN]

Great thread! Great idea! I have X800SE AGP but i havent heart so far anybody can unlock it. With my OC 580/1130 i would be pleased if somebody manages to do that. Do you still think PCB is the key.... not the core? That there is the hitch in it? BTW sorry for my English...i am from the Czech Republic.

 

[dolf]

Great, Meridius for the concern. I change my opinion about PCB but based on the experiment. Now I am working on the core locking and very soon your support will be necessary. I hope that you can work with multimeter because I will need some results (measurements) from SE core.

Stay on line with this issue and pray for us .

So....of course...i can set to work. I have simple multimetr...but it is still multimetr ))

I hope its digital...
