Dolf, I see that you and I are looking at the same places!

I've also noticed that the higher cards have unstuffed resistor networks on the topside next to the BGA, and the lower end cards have these stuffed. Some of the higher cards also have different resistor settings(either VCC or GND) as you mentioned before.

I propose a high res picture of every different version of card so that we can group them and figure out if certain setups have certain terminations. I haven't had time this week to do much investigation.

I'm interested in the R480.

Do the cut traces on the BGA correspond to pads on the BGA grid itself? This may be what we are trying to figure out.

Svart, thanks for the interest in that issue but I have to admit that my original idea about resistor configuration has now changed. Something is "disconnected" within the core and all the measurements connected with the core shows that. On R480 it should be equal but without laser cuts on the front side. If you have interest to understand what is under "core ground" we can work on that.

Unfortunately I am receiving less and less information all the time (concerning R420) and soon I will be forced to give up from the battle;) .

Probably somebody will replace me and will infuse a "new blood" into the research and finally will bring promising result:respect: .

Very usefull information . 10x Dolf and Sean478 for the hard work ! You guys made findings which are not really going to unlock the locked GPU's , but to understand how they're really locked. I don't think that there's a chance to change 990 reg, thus to unlock back side GPU locked GPUs , from the front side of the wafer, but we can always :toast: !

thx :)

yah i don't think there are pins that go to those lasercuts ither but its worth a shot if one of us ever gets another core. :)

(im realy sorry i broke that core dude :( )

Guys in order to unlock your cores I need some help from the owners of the X800PRO or SE AGP. If somebody wants to help me, please see the attached file and conduct the simple measurements described. I will try to discover what is possible and eventually to invent method for unlocking from the core-front side because on the back the things are more complicated.
At minimum I need to know whether one of the resistors enclosed with red is directly connected (zero ohm on the multimeter) to already cutted bridge spot (shown below) and whether one of the resistors enclosed with yellow is not connected with the remaining three?

Preliminary thanks to all of you for the support:)

Thanks a lot for the readiness. I think that I am very close to the success but need prove :)
If you need some additional explanation please ask.
But I am interested in "short-circuit" connections between these 8 resistors. One side of them is connected to GND (you have to find for you which side and to mark it on paper for every resistor). My interest is mainly to find or not to find direct connection on the other resistor side (end) but not connected to GND between these 4 resistors. Each group is independent and should be treated separately. If some resistor is not connected in paralell to the others and you start to measure from him you will not find other direct connection but GND. Take care about that. Just move the multimeter probe to other resistor of the same group.

Please If you succeed to find some difference than "short-circuit" (direct connection) point which exactly resistors show that difference.

If you find such difference it will be easy to unlock the pipes!

Something more what exactly card do you have?

Hello guys. I have HIS RADEON X800GT (8 pipelines, PCI-E, non VIVO, R480 (in atitool R423...), 2ns GDDR3...)

There are some photos (it's my article but now after reading this topic i found that my article is unuseable and bullshit at all)

http://czechgamer.com/hardware/X800GT%20-%20zvy%9Ate%20si%20v%FDkon%21.html


I want to help you, and don't know if i can, but if you need some infos about thic card, try me, i will do my best. (but no multimeter and so on, i am noob but want to unlock that pips! THERE MUST BE SOME WAY?!!!) I hope this card can... :ohwell: (and sorry my english i am from czech republic blah blah...)

I have HIS X800GT IceQ II Turbo. In some reviews in the internet is says that my card has R423 core. but when i ask HIS about this 'core thing' they say that all of HIS X800GT armed with R480. one thing i know is, so far, standard HIS X800GT is equipped with R480 and so far, in reviews i read, IceQ version is equipped with R423. in this thread i've read that shappire X800GT can be unlocked to 12 pipes by shyska. It is possible for HIS X800GT card to be unlocked to 12 pipes too. if it's not, why this happen?Both card has same core....

I thing your GT will have R480, not 423 as its on shyskas picture. GT from HIS allways have R480 core. And that's my problem too :)

BTW X800SE is R423 - it's from older RADEON X800. If you have R480 on your GT, the BIOS will say you that you have R423 - X800SE, becouse GT have BIOS from older RADEON X800... when you flash your BIOS from card which have R480, it will tell you on WINS that you have R480. it's only BIOS thing. just look at your core on your card for yourself, you'll se R480...

Yes you're right, but in this case i talk about HIS X800GT IceQ II Turbo. it's true that all HIS X800GT have R480 core but when we talk about HIS X800GT IceQ it's different. So far i've never found about IceQ X800GT with R480. You can see it it in link below. But i always found X800GT vanilla with R480

Can you unlock the lost pipe in your X800GT card

Ooh, another X800 GT with an R480 core! You should definately take a look here: http://forums.techpowerup.com/showthread.php?t=6056 :) Also post your bios there, so I can do a mod on it to have an HIS X800 GT R480 bios there, too. BTW, I will be modding it to say it is a GTO, since there is no such thing as an R480 X800 GT in the inf file for the drivers, which is actually the reason why no X800 GT is identified as R480 in the bios.

So, anybody know how to get +4 extra pipelines with R480 on X800GT? I goooogled for 7 hours but... no success... ATi ATi pleeeease, pleeeease, how to unlock that pipelines?!:cry:

If you are absolutely sure that you have R480 be sure also that you will NOT have more pipes at all. If not sure remove the cooler and see. Your chance is to have R423. Sorry for the bad news but please read the above and do the fuse research and post your results ;) .

dolf are you still working on the R420?

If yes, i just got an X800 PRO AGP and i can do the measurements
for you.

Hallo Folks,

i´m from germany and found your Board with google. I found many Informations but just want ask some questions before ich try to modifi my Card.

I´ve got a Sapphire X800GT 256MB AGP. It comes with 2.0 RAM & 420 Core.

Is ist right that i did NOT have a Lasercut?



This ist wat ATITool show:


A picture from the core:


When i understand from this Thread everything right i just need to flash a new Bios-File and i have 12 Pipes open? I don´t need to connect the points in lasercut-area because they arén´t disconected?

You HAVE to connect the right bridge (left is not disconnected). After connection of the bridge do again the fuse research and post results. Flash PRO BIOS using MODIFIED flashrom and the command "flashrom -f -p 0 (zero not o) biosname.bin".

Thanks:
Must i use a special Version or just download latest (Flashrom 2.40) from here?

http://www.techpowerup.com/downloads/Utilities/BIOS_Flashing/ATI

and as Bios-File i can user all PRO Files for my card? For example from here:
http://www.techpowerup.com/bios/
this file:
Sapphire X800 Pro (AGP) 256 MB Apr 8th 2004 3:37 PM Jun 17th 2004 2:48 PM 475 / 450
Samsung 2.0

???

But, how can i tell the BIOS to use 12 or 16 Pipes? Sorry for crossposting in two Threads but i don´t want to kill my card.

For the start just connect laser cut, that will probably be enought to get you 12 pipes.

Use PRO BIOS in order to allow 12 pipes. Your original BIOS allows only 8. You have to use not normal but MODIFIED flashrom in order to override the number of the active pipes on BIOS level ;) .

Please post your PCB partnumber here. (Front top side of the PCB - for example PN 109-A26100-XX)

Modified flashrom can be found here: http://www.techpowerup.com/articles/overclocking/vidcard/100

You already know from where to get BIOS. (I supose that your PCB PN is 109-A26100-00 )

The number of the active pipes is writen in the BIOS and could be changed manualy in hexeditor.
