Trouble unlcoking XFX 6800 XT pipelines and shader - Page 2

post #11 of 21
Thats why i still love AGP :d
You still can unlock your card. While pci blocks it.
Hope to have my xfx 6800xt soon Finnaly A better card then my ati9500.
And what i read its the best card for midle range price. Didnt wanted to pay much for an upgrade. Saving up for a new rig

I think so. I think the 6800GS is an overclocked 6800 vanilla, which means you should be able to unlock 4 pixel pipelines and 1 vertex ..thingy...what's it called?

Anyway, I just found out a guy is selling his 2 month old 6800XT (it's really rare in Indonesia). He said he could unlock it to 16pp/6vp but was scared of killing his card, but why would he sell it and buy a 7600gs? I'm going to check it tomorrow .

No pipelines to unlock on the 6800GS (PCIe version). At least not on mine.

From what i know you can overclock that card but you cannot unlock anything extra namely pipelines.
post #16 of 21
All I know is that most NV40 core based GPU can be unlocked to 6800GT level (although some pipelines may be laser cut or damaged).
This chart shows most of them (but no XT or NV41). According to it, the 6800GS AGP is NV40, so it's probably unlockable.

Edit: from Rivatuner.
Quote:
NV40 graphics processor's internal configuration is rather flexible and amount of active pixel and vertex units can be easily controlled by special GPU units configuration register. State of each pixel and vertex unit is mapped to the corresponding bit in the configuration register, logical 1 in this bit enables mapped unit, logical 0 - disables unit and prevents graphics processor from using it. This technique allows creating 16pp,6vp / 12pp,5vp / 8pp,4vp boards based on NV40 graphics processor core. So any NV40 graphics processor can be easily reprogrammed to use 1-4 pixel units (or 4-16 pixel pipelines) and 1-6 vertex units via masking the corresponding bits in the configuration register.
Quote:
First, you should look at the graphics processor's revision. If it is NV43 revision A4 or newer, then I've to dissappoint you - NVIDIA seem to progress with their hardware protections, so currently these chips are completely unmoddable. You won't be able to unlock hardware masked pipelines, as well as you will not be able to unlock professional capabilities on it. The same applies to all revisions of NV41, NV42, NV44 and NV47 graphics processors.
So 6800GS PCIe (nv42) is unmoddable. And anurevolution, I checked the Rivatuner FAQ, and it says that if the card is described as "NV41(A1,8pp,4vp)", then the mod wasn't successful. The custom settings are what Rivatuner is trying to force the GPU to. Here:
Quote:
Q: I have 6800 NU and right after installation RivaTuner displayed 12x1,5vp configuration on the main tab. In the NVStrap tab I saw that I have pixel unit 1 and vertex unit 3 disabled, so I ticked them and restarted PC. After reboot I still see 12pp,5vp on the main tab, however NVStrap tab shows 16pp,6vp configuration. What's going on?
A: NVStrap's status bar (displayed in the upper part of Custom graphics processor configuration panel) shows you default, current and target configurations. 16pp,6vp configuration you see is the target configuration, i.e. configuration you've asked the NVStrap to set after the next reboot. The value you should look at is the current configuration, showing which pixel and vertex units are actually currently enabled. Both context help and FAQ clearly state that the units can be hardware masked, so current and target configurations can be different due to your attempts to activate hardware masked units. So if you see differences in target and current configurations after reboot and see "disabled" state near the unit you tried to enable - it is protected by hardware mask. In this case you may either try to enable it using "Allow enabling hardware masked units" or forget about softmodding, if you don't want to risk with enabling a unit, which can be potentially damaged.
I guess this resolves the OP's issue...

i have same card and same problem as u.shows 12/5 in custom but when i open the program still says 8/4
post #18 of 21
I just spoke to 1 of the techs from xfx 2 days ago and he said the pipelines are lazer locked on my agp :swearing:
post #19 of 21
the only two cores from the nv4x line not laser cut are

NV40 and NV45

though finding an NV45 6800, 6800le, 6800GS, or 6800XT is hard, though most agp cards are NV40, because they are cheaper to make over all.

I flashed my 6800XT to a reg 6800 v2 bios and now I cant get the pipelines to show up right after restarting is there a way to know if they are unlocked or not?
