X800Pro,, 16 pipelines

[TyphooN]

are you sure? maybe thats why opp cant get his to work lol, but i thought u can have 16 pipe pro =/

[Hallowed]

Lol... they wont work at all without being flashed to the XT BIOS. The drivers will detect the device ID and run @ 12-pipe as soon as the driver is initialized. The pipes will be active, but the driver thinks "12" as soon as it sees the X800 pro devID.

You have X800 pro
You flash X800 pro, and immediately remove it when done.
You mod X800 pro
You reinstall 16-pipe X800 pro as an X800XT and you get into windows.
If you remembered to install 4.5 betas, it will work great.

[TyphooN]

ok, if you say so. i thought that flashing to xt was optional, and it isnt about the device id, even after the flash the device id remains the same. look on OC_UK, and you will see this, I still think it is optional after reading the OC_UK forum, but I will flash because it helps the mem overclock, cant wait to get a sapphire and i hope it works for me lol

i have try it on two Powercolor Cards, and the mod doesnt work.

[TyphooN]

as far as i know the only successes are on sapphire, none on ATi or powercolors.. but nobody has reported trying it on visiontek xtacy.. i wish someone would since its cheaper than sapphire.

[scrible88]

are the sapphires more expensive?

If so they might be charging the premium for "modability" lmfao

[Goldlocke]

no, Sapphires are most of the time the cheapest cards here in EU.

[TyphooN]

at best buy u can get bba for $400 free shipping, visiontek xtacy is $415 on pw with shipping, cheapest sapphire is $425 with shipping, and that is a local shop to me(the cheapest sapphire on pricewatch), so i guess ill just buy it from there.. unless i find out that the xtacy is moddable. i guess it might be a good thing to buy from a local shop, maybe i can try a couple cards and take back those that dont mod lol.

No, of course not.

Hallowed, have you tried the mod and experienced all that your saying? When you flash the card the device id doesnt change, its not the same as with other normal flashes ie 9800/9700. Whether you flash to Xt or stay with a Pro bios the deviceid is still 4a49 and the card is recognized as a Pro. The bios wont completely flash some parts seem 'protected'somehow.

I am running the card as a Pro but with the XT bios right now and the 16 pipelines are still showing fine. If this is the case and the mod is successful then there is probably no need for a bios flash at all, the drivers dont make one bit of difference.

I have read from other forums of other successes (although not many!) all with sapphire cards and even if you have a sapphire it doesnt seem 100% as Oppainter found out. I was thinking at first that he may have not joined the 2 points correctly somehow (although with his modding experience it seems unlikely), but now im thinking the 4 pipelines he is trying to re-enable are damaged in some way and when the drivers load the pc crashes. It may be that some Sapphire cards have totally broken pipelines which wont enable whatever you do, some have part damaged pipelines like Oppainters and a even less have the pipelines that are not damaged at and are all just disabled. Im no technical guru so I cannot say if this is definately the case. I have read that only 'clone?' cards are capable of the mod but this is hearsay though the grapevine which doesnt count for much......

I have read so many threads (not on here mind, apart from Hallowed) with people dishing out advice who havent even tried the mod themselves!! A lot of people seem to be finding it hard to believe its even true, hopefully the results Oppainter had prove it a little bit.

If any of you are really interested in the details on the top of the core I can get them when I get home from work tonight and post them on here, it might help to identify which cards may work although I myself cant tell the difference between one and another

[andyddr]

Chris_UK I`d like to know any numbers you can dish out like core date stamp or anything else on the PCB. Also how important do you think it is that you went all the way down to the copper on the PCB between the points? I`ve heard of a laser cut bridge between the points. Is there if fact one?

[BioBlade]

tomorrrow my x800 from powercolor is coming to my hands

on of the first in holland ,,

i want to try the mod , do you guys think ik could work >?

There is a laser cut between the 2 points, at least there was on my card. It is important I went down to the copper, because until I did that it didnt work

I have just borrowed the digicam from work, I will whip the card out tonight and take some definitive pictures of the working mod on my card, also get some pics of the core and whats printed on it. Bioblade, I wouldnt bother to try to be honest because it doesnt seem to work on any other models of card, unless you have a brainwave and try something new.....

[Boogotop]

hey Chris_UK....my mod look good for ya???

brilliant idea. thx!
When we look back to AthlonXP unlocking getting down to the copper layer meant shortening to the ground.
(If we assume that the copper layer on a FCPGA package like AthlonXP and X800 VPU corresponds to GND.) But why would that do the trick here? When u shorted an AXP mod to GND it was a no go.
Why does it help on the X800 VPU?

[Chris_UK]

as promised, heres the pics of the mod working on my card :



as you can see in my excitement I didnt even bother to clean it properly, theres a few bits of stray conductive paint lying about

[Chris_UK]

details on core :

[EmineM]

did you scratch a bit and then put conductive paint over it?

[Goldlocke]

thank you Chris. plz comment on my thoughts about grounding above.

edit: lol, hi eminem.

[andyddr]

Okay I have`nt got a clue what those numbers mean but if anyone else with a non modding X800PRO can tell us if there is a difference? Not that it makes any difference but what are those two dots on the T of ATI?

[Goldlocke]

I think there is only one way to confirm that we need to get down to the copper layer between the dots:

Chris remove the paint with acetone and draw a "U" line around the laser cut. Without touching it. If it works in that case, well, we dont need to scratch so deep.
Ofcourse I know that is a big request. It could be that the mod will never work again. So, just risk it in a moment of bravery!

@ Sapphire: Make your cards finally available here in AT!!!! damn it.

It could but the chances are far better that it won't.

Just make sure you know that your warranty is void if you try it which means you will not be RMA'ing it if the card dies, even it your mod didn't cause the problem.

The cards are incredibly fast anyway. Look at my scores on air with a regular X800Pro. If that's not fast enough for you then the XT probably won't be either.

The copper in the laser hole is not ground, it is part of the trace that used to connect the two pads. Connecting to it just gives you a better connection between the pads.

[Joe_the_tulip]

after reading all those posts I'm kind of confused now:

what do I have to do, for getting a x800pro working?

scratch the two points down till I see copper and connect them via silver conductive paint by just painting a line between them.

is that enough?

This is a good guide for the complete process. Chris has okay`d it so it must be good :smileysex
