[Geek3D-Test] FurMark, Catalyst 8.8 and HIS Radeon HD 4850: Torture Test PASSED!

Ok now that I have in my hands a HIS’s Radeon HD 4850, I played with this card and of course did the FurMark renaming experience with Catalyst 8.8 (see ATI Optimizes Catalyst 8.8 to be FurMark-Proof!). The difference of score in simply… incredible, better it’s shocking! Here is the score when I launch FurMark.exe: 2234 points

And now, the score when FurMark.exe is renamed in… ati.exe (why not?): 4383 points

This score is almost twice the first one. That explains now the odd result I get with FurMark in this post: ATI Catalyst 8.8 vs 8.7: OpenGL Performance Drop.

I launched in the same time the Catalyst Control Center in the Overdrive panel to check how frequencies vary:

In both tests, the frequencies were the same. ATI Catalyst 8.8 does not downclock the GPU frequency but makes the GPU running slower (what does it means???). Anyway, it seems obvious the Radeon HD 4800 series have some serious thermic problems. Maybe I could add a kind of GPU temperature limitation for Radeon HD 4800 series. If temperature exceeds 90 degrees on Radeon HD 4850 and HD 4870, FurMark will stop the rendering or will render one frame over two or three… But actually I think I’m not going to do that. FurMark is a torture test but it’s most of all a standard OpenGL application. I don’t use low level code or different rendering path for Radeon or GeForce. The same code is injected in both rendering pipeline. And then any OpenGL 2.0 compliant GPU should process this code if the surrounding graphics hardware (I mean memory modules, power MOSFETs properly cooled, etc.) is well designed and implemented by graphics cards makers. The proof, HIS’s Radeon HD 4850 PASSED all FurMark tests I did, with stock clocks as well as with overclocked clocks.

Now dear readers, let’s burn HIS’s Radeon HD 4850.

– Stock clocks: GPU=625MHz and Memory=993MHz

  • 94 degrees after 3 minutes in 640×480 no AA windowed mode: TEST PASSED!
  • 96 degrees after 3 minutes in 1024×768 no AA windowed mode: TEST PASSED!

– Basic Overclocking: GPU=660MHz and Memory=1005MHz

  • 96 degrees after 3 minutes in 1024×768 no AA windowed mode: TEST PASSED!

– Overclocking: GPU=680MHz and Memory=993MHz

  • 96 degrees after 3 minutes in 1024×768 no AA windowed mode: : TEST PASSED!

– Overclocking: GPU=680MHz and Memory=1100MHz

  • 97 degrees in 1024×768 no AA windowed mode. After 140 seconds, VPU Recover:

Yes the latest overclocking was a little bit extreme, but it shows HIS’s Radeon HD 4850 is a very good product and is already FurMark-Proof. No need hidden tweak in Catalyst to run FurMark. I think graphics cards that do not resist to FurMark torture tests are either bad quality products or have some bad cooled parts like the VRM (voltage regulator modules)…

ATI Optimizes Catalyst 8.8 to be FurMark-Proof!

Here is an incredible news to start the day: Expreview has found that ATI’s Catalyst 8.8 have been optimized to detect FurMark and downclock the frequencies of a Radeon HD 4850/4870 to avoid to burn the GPU.

So if you have a Radeon HD 4850 or Radeon HD 4870, just rename FurMark.exe in something.exe and you will see the difference!

Expreview has done the test with Quake Wars: Emeny Territory and has renamed etqw.exe to FurMark.exe and saw performance drop from 141.3FPS to 93.7FPS!

I have not a Radeon HD 4000 series but I think that I’m going to buy a Radeon HD 4850 today!

It’s a pain to develop a benchmark to make it running properly on most graphics hardwares and now I have to include in FurMark a Catalyst anit-cheat???? Thanks AMD/ATI….

Why AMD doesn’t contact me directly to find out the problem???


PowerColor Radeon HD 4870 Fails to Complete FurMark

Expreview has done some tests on the new Powercolor product, the Radeon HD 4870:

One of these tests is FurMark and the HD 4870 fails to complete one minute of FurMark’s stability test. Failure symptoms are VPU recovery message, red LED (on the PCB) that shines…

For one thing, BIOS limited fan speed too low, that results in a higher GPU temperature; For the other thing, it gets through 3DMark Vantage, but fails to complete FurMark test. We believe it’s the BIOS setting that causes these problems and asked PowerColor for a new BIOS, but the answer was not available yet.
