I don`t know is it normal. But I would not try to fix that

I know that with 3.2 that they had applied some ati clock reading fixes. Maybe there is still some bugs.

erocker · Mar 18, 2009, 08:04 PM

How did you get one to show 640 and the other 800? Is it random?

W1zzard · Mar 18, 2009, 08:05 PM

are those two 4830's ?

DarkMatter · Mar 18, 2009, 08:10 PM

LOL he got a 4830 with an actual 4850 inside??

Texture fill-rate is calculated from the number of clusters or is it readed from the card too?

Foen · Mar 18, 2009, 08:22 PM

its not random its one card the hole time switch them from pci port aswell the card stays at 800 shaders

alexp999 · Mar 18, 2009, 08:24 PM

What happens if they are not in crossfire, i.e if you plug the one reporting 800 shaders in, on its own?

going to test now !! back in 2 min

crtecha · Mar 18, 2009, 08:26 PM

im gonna die laughing if they are two different cards

alexp999 · Mar 18, 2009, 08:28 PM

If it comes back that the card on its own still reports that it has 800 shaders, then it could well be they got lucky and actually have a 4850.

Foen · Mar 18, 2009, 08:29 PM

back Still shows 800 shaders going to flash bios to the other card aswell

W1zzard · Mar 18, 2009, 08:33 PM

so you have two 4830 cards. one shows 640 shaders and the other shows 800 shaders?

always?

only when in crossfire?

all time

Foen · Mar 18, 2009, 08:39 PM

i have 2 XFX ATI HD4830 card 1 show up in GPUZ as 640 Shaders and on as 800 Shaders

W1zzard · Mar 18, 2009, 08:41 PM

then you got lucky and have an unlocked 4850 chip there. flashing the bios will not unlock shaders on other chips as far as i know, but give it a try

alexp999 · Mar 18, 2009, 09:07 PM

afaik, the BIOS actually reads the GPU for the shader count. MF's cottoned onto the fact we were flashing lower iteration cards to their full power and so now laser lock the actual GPU.

XFX obviously made a cock up at the factory and stuck a 4850 designated GPU on a 4830, to-be board.

Bucknuts77 · Apr 10, 2009, 03:37 PM

The shaders are laser cut from 4830's to have 640. So grats to you for the company mess up, lol
