X800 fuses data for unlocking

[manoloxxl]

Absolutely correct but don't forget to flash using modified flashrom (from here: http://www.techpowerup.com/articles/overclocking/vidcard/100). If you succeed with 12 pipes and your left bridge is originally disconnected you can go further for 16 pipes by connecting it also. The chance for 16 pipes is close to 0 but there is always some. Point 7 depends on you .

Must i flash a new Bios (PRO) or can i use my old?
You mean that it also will be possible to connect the 2 Points on the left and go to 16 Pipes?
But first i try to go up to 12

try if u like, at first with the old one.. should boot! maybe with only 8 pipes

if only 8 pipes flash the bios and see if u got 12 then..

It looks like dolf was correct in saying that your card would most likely have an R480 chip. BTW, did you take the heatsink off to look at the gpu or did you just decide to flash to that bios without checking first? If you didn't check first, well, it doesn't really matter now, since getting that performance boost confirms that it does indeed have an R480.

No I took the heatsink off and it said R480. It is the right bios, right? And there is not anything more I can do to get better performance?

I now get around 5100p in 3Dmark05 running at 600/590 with 3200+ @ 2500MHz.

Ok Folks. It´s done!

Here is a Screenshot from ATItool after i have connected the two points:

Then i flashed my old Bios. But nothing changed.

Then i have flashed the Sapphire X800 PRO Bios from this site. And now, great great great, just look:

20 = all 16 Pipes???? I didn´t testet anything yet, but now i will start 3dmark05 for testing. This is crazy.

The card is recognized as a X800 XT, don´t know why, but it´s look like it´s working?!

Thank You Thank You thank You!

@Manoloxxl
You still have 8 pipes

 

[manoloxxl]

I´ve tested with 3dmark05 but you´re right. It seems that there are just like bevore 8 pipes open. Same result (4200 points)

But why??? The ROM_FUSES changed

 

[Matthew]

fuse change because you have flashed with pro bios.
do you have connect the bridge using a pencil ?

 

[cLy_eVo]

stop trying so hard. spend your time using it rather than spending time tweaking it. i cant mod my gto to 16, but it still clock so well with just 12 pipe. i'm still paying much less than an x800pro for performance that are much superior than it. 5708 w/ 2ghz cpu

 

[manoloxxl]

I have used "silver color" and a little stick. Is it bad when i connect the lasercut with the 2 points oder must the connection be without the stripe from the lasercut.

I want the extra pipes

 

[Mr_Torch]

this is only for x800 series old cards dont have fuses

My card is an X700 Pro PCIe 256 Mb and it shows it has fuses, does this posibly mean that I can unlock some pipes? Currently only has 8 pipes.

Now you have to flash the BIOS with one with 12 pipes. The PCB part number is differentn than the normal PRO that's why it is better to use modded BIOS. Please send me (post it here) your original BIOS to mod it for 12 pipes.

Here is my file.

http://www.manoloxxl.de/treff/bastel/x800gt/sapphire_X800GT_R420_AGP_org.bin

Can you explain me how you mod the file? I want to help other guys in a german board wich are trying to unlook cards too.
You can also upload this file to the Bios-section if you want.

Tomorrow I will mod your BIOS and will try to explane you how to do it youself. Now I am using outsiders computer and have no suitable software installed on it. But you will need Hexeditor and RaBit 1.7 to do the mod.

ATI/Dell X800SE PCI-E

Just some info for those with 128MB (Hynix 2.8ns) PCI-E Radeon X800SE Cards. Most of these cards were sold in Dell systems as far as I know. Perhaps the info could also be interesting for those people who recently bought X800GT cards, but I don't know for sure.

My card is equipped with a R423 chip and has a single laser-cut. I first powered it up unmodded, so the laser-cut was untouched and the info shown by ATiTool was the following:

die_fuses: 0xEFF3EFFF
substrate_fuses: 0xFFFFF61D

I already had the suspicion that this card could perhaps be turned into a 128MB Radeon X800/Pro by enabling 4 extra pipelines. The problem I saw was that there was not a single BIOS for any PCI-E X800Pro/X800 12 pipeline card with Hynix 2.8ns RAM, let alone with only 128MB of it.
Then I thought, well there might not be a BIOS, but let's see what ATiTool shows when I reconnect the laser-cut bridge. Connected the bridge as planned, with some conductive silver lacquer et violà, 12 active pipelines without any extra BIOS flashing.

Fuse data after connecting the formerly cut bridge:

die_fuses: 0xEFF3EFFF
substrate_fuses: 0xFFFFF61F


Perhaps this could be of help for anyone with one of these cards out there.

Edit:
Just one thing to add. The thing about the ROM fuse data and it's ending must either be completely wrong or I am missing something. My card had it ending with a "2" when it was unmodded with only 8 active pipelines, but it's still ending with "2", although I have 12 active pipelines. There's definately something strange here.

 

[noneed4me2]

celemine1gig, try this prog out to make sure all pipes are ok High Dynamic Range based Torture test, just google Rthdribl. That is odd about the 2 though as i have read a ton of posts and insofar everybody else's numbers usualy indicated that the bios was locked, there was even a thread where someone (shadowflre,infrared,Dolf if you guys know the link I can't find it) lowered their pipes by modding the bios this way, and then back up again. Can you post 3dmark scores and any other benchmarks, I am curios as i have a family member wanting to get a Dell. Also the E's were thought to indicate which pipelines were disabled so now that you have 2 that would seem to show that 8 pipes were inactive. I had weird readings after flashing in ATITool and had unin/reinstall and that fixed it.

 

[infrared]

I'm not sure if this is related or not. It shows how to mod the pipes up to the 16.

http://www.techpowerup.com/articles/overclocking/vidcard/100

Seems you have to use a 'modified flashrom' (there's a link to it in the article) but this seems the only way to do it without physically bridging the lazer cut.

If anyone attempts the mod, be sure to tell us how it went!

This would be great. I just downloaded the tools and still waiting for my new bios. At time i´m at work so i can´t test anything yet.

 

[dolf]

The information about the number of active pipes hides in address 0x000070 and exactly represents CONFIG_ROM_FUSES value. In your case it is in 0x00007C with value 22 which means 2 quads blocked. 21 will mean 1 quad blocked and 20 - 0 quads blocked (16 pipes working).
I have compared SE BIOS and your GT and they are almost equal. Normal PRO BIOS should work for you also. Don't forget to use modified flashrom.

 

[manoloxxl]

Thank you. I will flash it in maybe 5 hours when im finished work.

I´ve tryed to find the entries. But maybe i´m blind. I´m using HEX_Editor MX but can´t find Row 0x00007B
My Rows begin with 0x000 and end with 0xDBF0.

Also i look in row 0x0000 at position 07 but there is only 00.

 

[dolf]

I've did a mistake the position is not 7B but 7A
I hope that this will help you :

 

[manoloxxl]

Allright, i found it. Thank you.

I compared the files and found 6 changes, why happend this?
Sorry for asking so much, i got no time to test the file so i want understand what to do.

sapphire x800gt spec

Hi all i have a sapphire x800gt i think the chip is a R423 and it has laser cut a the top of the Gpu.
is my card moddable to 12pp ? if yes with wich bios should i flash? thx !

here are my ati tool screens

 

[manoloxxl]

When i open the files from dolf with rabit i get the message that the bios is corrupt, is this because of the change?
Can i change in my moded bios the core-clock with rabbit?

to open dolf's bios have you used RaBiT-1.7?
