Help flashing a 4850

Hiya,

This is on a 1GB Asus 4850.

I've burned my fingers playing with Catalyst after vowing to never install it again.

I've got artefacts all over the screen, even during post. I've tried using the Asus flash utility. That doesn't do anything. I've managed to uninstall Catalyst but whatever it's done to my card is stuck.

I've reinstalled Catalyst but it wont start as it won't recognise the card. Says the driver is incorrect (even though the driver is installed at the same time)...

I think I need to flash the 4850 bios unless anyone has another suggestion?

I have a USB stick with DOS on it which I've used to flash the motherboard bios with. I'm a bit concerned that I can't seem to find the actual bios to flash!

Any help out there?
 
Right, well now I'm royally ****ed.

I flashed the bios using atiflash and what I thought was the original bios for the card. Ended up with no video at all... :rolleyes:

I've tried flashing another bios "blind" but that's not worked either.
 
May I ask why you wanted to flash it in the first place? If the card is working fine, their is no need to flash it, plus who in hell flashes a gpu? Ok the 6950 to 6970 was an exception.

Catalyst is needed for amd cards, its basically the nvidia control panel for amd cards.

If you were looking to overclock the card, then use a program like MSI Afterburner.

Their isn't much need to mess around with the catalyst software unless you really need to change some things but for gaming, you don't need too.

You have artefacts then yes? It looks like you have messed around with some options you don't know how to work or don't even know what they are and they have screwed your gpu over.

Now you have flashed it. Did you make sure you flashed it to the "original" bios that was already installed? It would have just overwritten the bios you had on it and fixed any errors the card had.

Or did you flash it to the latest drivers?

If you ask me the card is dead and you need a replacement and you only have your self to blame.
 
I had to flash it as the changes catalyst had made (with little persuasion I might add, and I didn't go mad doing things I knew nothing about) this was no extreme overclocking, just some playful adjustment that worked fine for some weeks using ATI overdrive. Then today - writing an email - boom - red stripes and dots all over, which didn't go away on restart. Blue screen just before login, would only boot into safe mode, where catalyst doesn't work. Reinstalling drivers did nothing.

I found a link on the asus forums to what should have been the original bios for an EAH4850 1GB but it's killed it.

I don't agree with catalyst being needed. I've probably had it installed for a total of 2 months whilst I've had the card. I usually just standard drivers with no overclock. Every other time I'd installed it, it resulted in worse performance or blue screens.

I was playing around with it trying to reduce system temps. At first I'd fully (with overdrive) underclocked it, but then noticed performance issues, so upped cpu and ram clocks.

To be honest, I actually think the card was still underclocked when the artefacts appeared. Was running at a cool 38 degrees.

Oh well - been thinking about getting a 7850 anyway.
