Itt van angolul is :)
While we're not quite sure what part of the Catalyst 3.8 drivers are causing this, some part of the driver (whether it's the new VPU Recovery feature, HyperZ Enhancements or the ATI Overclocking software) is causing the core on BBA and OEM Radeon cards that are identified as ''RADEON 9800 XT'', ''RADEON 9800 PRO'' and ''RADEON 9800'' in Windows to have their GPU's overheat by as much as 15*C over normal during 3D graphics sessions. This has caused a number of fans on the Radeon 9800 XT series to fail, allowing the heat to completely destroy the card.
This news is especially important for individuals who performed the 9800 to 9800 Pro BIOS flash and did not include additional cooling on your card, as the GPU is already overclocked and producing more heat than normal.
As a safety precaution, I am strongly encouraging that anyone with any of the affected cards above roll their drivers back to the Omega Catalyst 3.7 drivers or the ATI Catalyst 3.7 drivers, as they are verified not to cause this overheating issue.
I did some testing with my Radeon 9800 NP BIOS-flashed to a 9800 Pro. The results are not encouraging.
Running looping 3DMark2003 for 30 minutes and utilizing a temperature probe on my GPU (regular cooling), the following temperatures were recorded:
Catalyst 3.8: 135 Fahrenheit
Catalyst 3.7: 117 Fahrenheit
The heatsink on my Sapphire Atlantis 9800 was so hot during the Catalyst 3.8 test that I burnt my hand when I accidently touched it.
2) The Catalyst 3.8's seem to have a bug in some systems that allows the driver to process the SECONDARY adapter settings when a game is started and tries to switch to the resolution and refresh rate specified in the program.
Normally, the card is limited by the INF file settings for the PRIMARY adapter, so that no resolution or refresh rate is attempted that is beyond the capability of the monitor hardware. But in the 3.8's, it seems to be processing the SECONDARY adapter settings first. In a system without a monitor plugged into the second adapter, there is no INF file limiting refresh rates and resolutions, so, the system is trying to force refresh rates and resolutions beyond what the monitor on the PRIMARY adapter is capable of.
So instead of having the monitor ''flicker'' once when it switches to the desired resolution/refresh, monitors are ''flickering'' between 4 and 8 times, with resolutions and refresh rates that are beyond the capability of the actual monitor. As a result, some monitors have been damaged, while others have blinked out and recovered. Some users monitors are under warranty and can be RMA'd, but for those who don't have a monitor under warranty, their monitor is damaged and they must buy a new one.Liƒє is too short. - http://www.lowcostdomain.eu

Mondjuk erre csak annyit tudok mondani, hogy az én 9100-asom lehetvékony bordával és mindenféle ventillátor nélkül (behalt és nem raktam rá másikat) 270/270-en vígan elzötyög, igaz a hírben leírt tesztelési módszerrel (kézrátétel) szintén tűzforró :) De még nem sült meg :D

igy újra átolvasva izé nem is tudom valami másodlagos INF fájlokrol beszél. Az elsödleges helyett használná azt, de ha csak 1 monitorod van akkor ugye nincsen másodlagos inf, s a saját legmagasabb frissitési frekit proáblja beállitani. remélem már jol forditottam.

Nagyon régi lehet az, az én 2000-es GABA (!) 15 colosom kiröhögött, amikor túl nagy refresht állítottam be... persze ha nekem vinné szét a cuccost, biztos hogy én is anyáznék éktelenül ;]
De ez a kártyasütögetős ez ismerős valahonnan... nem az egyik Detonator csinált ilyet valami 3D-s képernyővédők alatt, hogy nem pörgette fel rendesen a flóefikszet?And As It Is Such, So Also As Such Is It Unto You

Egy hír valóban megérdemelt volna a dolog, de azért én nem mutogatnék ujjal... mellesleg ATi tagadja, hogy az uj driverek bármi kárt okoznának:
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.

Nem lehet, hogy ez a hír is olyan, mint a lentebb említett Detonatoros FX-égetés? Csináljunk balhét, hogy rólunk beszéljenek... Egy forrás nem forrás szerintem -bármennyire hihetőnek tűnik. Valószínű, hogy nem egyetlen embernek van 9800-a, és hogy próbálta a 3DMarkot is... Nem? :)
