View Full Version : Flicker problem is BACK with 5900u flashed to 5950

I was a sufferer of the notorious 5900u flicker problem. Ever since driver 45.33, my problem has not appeared again.

However.

I flashed my BFG 5900u to a BFG 5950. Everything went perfectly, and I can overclock significantly more. But the flicker problem that existed before has come back. I notice it most significantly in Battlefield 1942, and Unreal 2. I dont notice it very much at all in Far Cry, or Star Wars: kotor. (DX8 vs. DX9?)

This problem does not seem to be related to the driver version, as I have tried 53.03, 56.55, 56.56 and I even reverted to the 45.33 and they all displayed the flicker.

I'm wondering if nvidia only applied the flicker fix in the driver to the 5900u, and now that it thinks that I have a 5950 that the fix is not applied any longer.

Any suggestions (other than obviously flashing back to the 5900) would be much appreciated!

I did not notice this problem with the Asus 5900u I flashed to a 5950.
But all the Asus cards run hotter than most other 5900's.

Just an update.

Flashing back to the 5900u standard bios FIXED this problem.

It's not exactly the solution I want. It's probably the driver that doesn't make the proper adjustments to the 5950. The only other option is that the boosted voltage from the 5950 BIOS causes this problem.

Anyway to force FORCEWARE to find a 5950 as a 5900? I'm guessing this will give me the benefits of the flashed bios, AND the flicker fix.

Thanks!

I forced the driver to the 5900 in device manager (which worked), but the Nvidia Display properties still finds it as a 5950.

Flicker still there.

Same problem here, BFGtech 5900Ultra flashed into BFGtech 5950Ultra.

Seems like the temperature is back down to the 5900U + flickering drivers level..

I saw that there were a few different BFG5950 BIOS's out there.

Perhaps a newer one might make a difference.

Have you ever considered the notion that perhaps your card is trying to tell you that it opposes being BIOS flashed? You might want it to work, but sometimes it just doesn't. The 5900 in and of itself is a good card, be happy with what you have.

If we were all "happy with what we have," I'd guess that 80% of the posts at nVnews would be gone.

We all push our systems to the max, and figure out problems as we go.

It's fun.

And I think I'm dealing with a software issue, not a hardware issue.

I have a bios flashed BFG Asylum Fx5900u@Evga380u5950u bios running at 530/1000 and I don't and have never experienced any of the flicker problems. Even before the bios flash and before the Flicker fix driver. Maybe it's because I'm using an 18" Samsung LCD on digital. :confused: Although I don't remember having flicker on my CRT Display either.

Anyways, I'd also recommend just using the regular Fx5900u bios and overclock it to 5950u speeds. You won't be able to overclock as much, but atleast you won't have the flicker problems.

I have the same vid card BFG 5900 to BFG 5950U flashed. Works great with no problems. I even posted on one of the threas here the BIOS I used to flash with. I haven't tired TV-out yet though. I think I will do that now.

The 5900 will not get there with out BIOS flash. I tired it before I flahsed BIOS and my card would barely OC at all.

Obviously you missed the entire point of my post. Perhaps your card has reached its limits and flashing its BIOS pushed it too far. Not everyone will have success in trying to get something for nothing. If your card works fine without the BIOS flash but messes up with it, what makes you think it's a software issue?

The original flicker problem was a software issue.

This problem is identical (with the same card) so I think it's related to the driver.

Hey, if I cant fix it, I'm happy to go back to the 5900 (which I have) but if people have ideas, I'm all ears.

goofjb,

Any flicker?

Did you experience flicker with this card before the 45.33 drivers?
