Please uninstall cat 3.8 from your machines pronto as I was reading at overclockers.comthat cat 3.8 is making monitors drop like flies. I noticed my monitor was doing this crazy flickering stuff and it's fixed since I went to 3.7, apparently mine was just about to die. But from what I've read some 183 monitors have suddenly died to due to 3.8.

Cheers and hope no one has to go through this b.s.

RESPONSE TO ALLEGED MONITOR FAILURE ISSUE

We have spent a great deal of time trying to reproduce this problem and analyzing our driver code. There is nothing in our driver code that has changed since CAT 3.7 to CAT 3.8 that could possibly cause this behaviour. We believe that our drivers are not causing these alleged problems.

We do not currently believe these stories are valid. We have already confirmed that of the nearly 100 OEM customer programs have asked for and received this driver, we have received no reports on any such problem from the OEMs. We have also run comprehensive QA tests on the driver before releasing it and have had no cases of failed monitors.

Since we announced CATALYST 3.8 on October 8th, we have recorded hundreds of thousands of downloads, and thus far there have been absolutely no reports whatsoever to ATI's Customer Support department to report monitors failing.

RESPONSE TO ALLEGED HARDWARE OVERHEATING ISSUE

We have spent a great deal of time analyzing the temperatures due to the CATALYST 3.8 drivers. We do not under any circumstance see anything near a 10 degree Celsius increase in temperature (but we don't overclock our test cards either). We do see a slight increase in temperature in certain cases (3Dmark2003 Nature Scene for example). However any temperature increase is well within our safety range. Investigation continues and we are trying to determine why this change in temperature exits. At this point we are reproducing individual driver packages with code being checked in and measuring the temperature. However nothing shows the alleged increase in temperature. One independent website even tried to reproduce this issue, and found no measurable difference in temperature between CATALYST 3.7 and 3.8.

TECHNICAL REBUTTAL OF MONITOR FAILURE ALLEGATIONS

There have been many posts in the forums discussing this issue, it seems it is a common theory, picked up from one place and keep being circulated. One such theory suggests the following:

"Instead of reading the refresh rates from the PRIMARY display INF files, it is reading the SECONDARY display INF refresh rates."

In XP and 2K, we don't have access to monitor INF information in our driver component that manages display capability. We have never used this monitor information for any purpose. We rely on EDID data or user override information to determine monitor capability. Even though the OS may use the monitor information to expose high refresh rate based on monitor INF content, the driver always restricts the actual refresh rate going to the monitor based on EDID or the user override. In essence, the user may be able to select from OS controlled monitor page (in advanced property pages) a high refresh rate but internally driver will restrict the refresh rate going to the monitor based on EDID information or user override information. If user set the override information incorrectly then incompatible signals would be sent to the monitor.

In 9x, we can access monitor INF information but due to issues with how OS maps the INF to a monitor, we had disabled reading the monitor INF via registry. Unless someone deliberately changes the registry setting for this in 9x, they would not run into any monitor INF related issues.

ive had no problems with flickers or anything with my monitor... but performance drops like mad =\

Theres no way they can prove that theyre not the ones causing this... 180 monitors suddenly being fried? theyre just trying to not have to be the ones to replace those monitors

180 monitors? Anyone have evidence of this?

I've read a heck of a lot of posts about this, and I haven't seen anyways near that many people saying they have been effected.

I got the 3.8's about 2 minutes after they were posted and have had no problems at all.

ya i have seen a lot of posts as well but i have only seen one person who actually made the claim that the drivers fried his monitor, and it sounded like an old monitor anyway so it may well have just been the things time to go. ohh, on a side note i reacently saw a guy who claimed the 5950 fried two of his lcds in a row.

Rubbish.

I asked for his sources and he couldn't give me an validity about specs, temps, hardware, and programs used on those "180" computers.

Total BS

I have 6 customers plus myself that are running 97/9800s with the 3.8s with no problems.

I'm running just dandy on the 3.7s, no reason to install the 3.8s. I've only got a 9600 Pro, so its not like I get OverDrive

People forget driver updates fix bugs as well ;) ,anyway I`ve been using 3.8s since the release date and have had no problems at all,I`m using DVI mode on my LCD and from what I read it does seem to be only a CRT problem(not seen any LCD problems).

im thinking its something to do with certain cards, i tried cat 3.8 on a 9700 pro and it did the moniter shutting off and losing signal , then i took the card out put in my bakup card (G4 MX420) and unistalled all the drivers and used the drivers off of the ati cd. then i realized that my 9700pro was bad. to make a long story short. i took back the 9700 pro and got a replacment 9700 pro installed it with cat 3.8 and i have no problems.

It could be the cards, or even the overclocks.

I had a weird problem using the omega leaked dell 3.85's I run a 9500 Pro and when I loaded CS the refresh rate would jump to 160hz according to the monitor I was running it at 1024x768. While I know my monitor is nice I know it does NOT support that high of a refresh rate at that res. It only supports up to 120hz so I quickly closed CS to make sure it wouldn't damage it permanently. I switched back to regular cat 3.7's and have had zero problems like that. Not sure if it is the same thing happening to these alledged monitor failures but I just thought I would add some info.

if the monitor reports the refresh rate, that is because it is supported. if it wasnt supported your monitor would have shut off as all recent monitors have an auto-protect feature.

That it what I thought but according to windows, reforce and the manual my monitor can only get to 120hz at 1024x768. The monitor said that it had a "new profile" or something and was out putting 160hz on the diagnostic screen. So I donno about you but im pretty sure something was wrong especially if it THINKS it can do that much.

Great, now I'm having vision of me jumping out of bed and running into the computer room only to see that beautiful Nature scene in 3DMARK2001SE...on fire!

I've been using the Omegadrivers (based on 3.8) and only have good things to say if that helps anybody?

What diagnostic screen are you refering to?

Do you have a 121+KHz monitor? You need approximately that much to get 160Hz in 1024x768.

Well, maybe I was wrong about running 3.8s. I checked my driver information, and it has a date of a couple days after 3.7 was released. However, my control panel is definately 3.8. I had a really hard time getting the 3.7s installed in the first place, so its possible the 3.8 install looked normal, but didn't do a thing except put the control panel on.

Maybe someone can help me with this...when I uninstall all my drivers, Windows will only load the ones on the cd that came with my card. If I try to run downloaded ones, it gives me an error saying INF file not found and won't install anything. I got 3.7 installed by doing the cd first, and then installing 3.7 on top of that. I think my cd version is 3.5

If I try to manually tell windows where to find the driver, it gives me a list of all the radeon cards, all except 9800 se which is what I am using, so I can't do it that way.

Not like I am too anxious to go to 3.8, but it would be nice to figure out what is wrong so I can install 3.9 in peace when it comes out.
