Anyone with a 48xx and Vista 64?

[Eggman]

Same problem as everyone else - cant run a game or benchtest for more than 10mins usually without it black screening or bsod and then rebooting. I have only one monitor and a 4870 x2 at stock.

what is the best driver at the moment for stability

 

[d3sbo]

i trust every one has got occt or prime95 on large fft stable
a lot of my problems came down ot memory but memtest86 would not pick it up

Has this "Stopped responding" error been fixed yet? This has reared its ugly head to me now again. I have re-installed Vista x64 twice. This does not happen at all with an 8800GTS I have. It happens on both my x64 machines. I have tried 8.6, 8.8 and the 8.9 betas, no difference. Both machines are stable and have never BSOD'd before or had this error. The only variable is the graphics cards.

AMD fobbed me off saying that it is my system, which I refuse to believe if it runs fine with a 8800GTS and a HD2600 Pro I have lying around and it survives any stress testing I throw at it.

Are there any solutions? If not, looks like I might get a GTX 280 instead if it is not fixed int he 8.9 final this week whenever it is released. Not happy, the ATi I remember had solid drivers. I cannot use my system for more than 1 hour without this stupid error, and if it happens ingame it BSODs on the driver.

I know how you feel, i re-installed Vista x64 four times! you're going through all i went through... and still no fix, but this has been around since Vista release so dont hold your breath waiting for a new driver release to fix it.

It's disgusting how ATI will not admit they have a problem, when many hundreds of people on there OWN forums have this issue, not to mention on countless other forums. Thats what pi**es me off most.
Even Nvidia admitted they had a problem in early Vista days with there 8800 drivers.

In the end i sold my X2 and got a 280, no problems even with it highly OC'ed and with the latest BETA drivers performance has increased. For me even NV's BETA drivers are 100% stable and have less bugs than ATI's finals.

I have seeminly fixed it now, a BIOS update seemed to resolve it and now it seems fine.

I was reluctant to change to a GTX 280 as these 4850s are faster in most situations I play in.

Glad it is resolved now. Hopefully the 8.9s won't ruin it.

I have gone through nearly every post in this thread and I really do feel the frustration of those owners of the 48x0 cards experiencing problems.

What I have noted with my Sapphire 4870...

To give me the best stability and experience I ensured I had an adequate PSU.

OCZ Xsteam 800W delivering 62 Amps.

Removed CCC and now just use the 8.8 drivers.

Dumped the BIOS from the card and then modified it to fix the loud fan spin up bug during boot. Also I changed the Tmin and Tmax fan settings in the BIOS to cool the card more effectively. Then I flashed it back to the card.

With the above I only needed to use ATT for overclocking and hotkey support.

I have noted an 'issue' with the erratic behaviour of Powerplay and it being way too sensitive on switching from 500mhz to 750mhz when in 2D...

however, as I assign an hotkey to an overclocking GPU of 760mhz, I apply the hotkey and then another hotkey to reduce it back to normal 2D speed of 500mhz and I then get the following when using 2D apps...

(notice the GPU speed fluctuation top graph)

..absolutely no switching whatsoever.

I have used XP32, Vista 64 and XP 64 (I currently use XP 64 all of the time now).

I have tried dual TFT's under the above OS's and found no problems at all, but only since I applied the above settings etc... However my time with two TFT's was limited until my wifes PC was up and going again.

I have reported my observations with the erratic PP to AMD/ATI and suggest that the people here, if you have not done this already do the same...

In an effort to help catch potential issues, I would kindly ask everyone to report ALL issues you're experiencing via the Catalyst Crew Feedback Program. This program was implemented to help catch potential issues with newly released drivers so that we can quickly report back to software engineering. This is the only official mechanism for AMD/ATI to track driver issues.

Good luck with your problems

Glad you sorted it & its not the first time that its been a mobo Bios issue which many would not even think about unless they see it mentioned and as the saying goes, " don't upgrade the Bios unless you have a problem" & lucky that you remembered that you were not on the latest bios which ATI would not know about in your correspondence with them.

I see in another thread that an OS timed harddrive spinning up on an Asus mobo was crashing the ATI gfx driver, who would have thought.

In both these cases its impossible to lay the blame at anyone as there is noway that ATI can test even one gfx card on every capable mobo with every bios revision with every CPU with every harddrive with every memory & PSU type on every OS and as time has gone on i have seen problems fixed because of all of the mentioned above that has been a cause at some point & most of the time.

On some forums its mandatory to have the mobo,bios,OS+SP,ram+type+amount+timings,harddrives+ raids,PSU in a sig or in a user info menu it can sometimes cut down allot of time in finding a solution for an individuals problem.
I would like OcUK to implement the user info menu option with option to view FULL details specs.

It takes more than 2 to tango on a computer & its a miracle that it works at all on a non closed system.

Oh and of course the ATI drivers need to mature.
