How far have you OC:ed your ATI Radeon 8500?

  1. I'm creating this thread in correlation to the news post I made on the homepage...

    If you are so kind as to post your results please also post what the default speed of your card is (i.e. 230/230, 250/250 or 275/275mhz)

    And also what brand and exact name it is of, i.e. mine is a "Built By ATI" Retail ATI Radeon 8500 64MB with a clock of 275/275mhz...

    And lastly what cooling you have for it (read further down for more details)

    The best method I have found to test the stability of my ATI card has been to only run the "Point Sprites" test in 3dmark2001 with "looping" and "disable title screens between tests" selected...

    A little background on what sort of cooling my ATI card gets, I have the case cover of but since I'm watercooling there are no fans directly circulating air onto my ATI card, I tried with first removing all PCI expansion cards this only made the card pass about five more tests for a toltal of ten (though it could also crash after just one...)

    When I put a big 120mm fan which blows ca 120cfm of air across the card it took about 30 minutes before the comp crashed...

    So all in all; I'm only using standard cooling, and there is no additional airflow inside my comp to help in the cooling of my ATI 8500...

    My ambient temp is around 21°C

    295/295, with no extra cooling. It lasts a good 4 hours before becoming unstable during intense gaming. Otherwise, it's always stable.

    High instensity RTCW sessions seem to heat it up a little too much for it's teeny fan to handle :D Those new 6037 drivers are pretty good. Not a HUGE improvement, but an improvement nonetheless. (couple more fps it seems in RTCW)


    ---I have the official ATi Radeon 8500. (only $140 at all Best Buy's for the time being).

    What do you guys mean when you say "going unstable"? The computer just freezes/crashes? I would like to overclock my vid card, but I read these warnings saying it could damage the hardware. That's something I don't need. I paid full retail price ($199, I think) for the card, and I don't feel like spending another bundle...

    ...How high can you overclock it and still be stable/safe?

    Unstable can either mean that you start seeing visual bugs on the screen, or that the game just crashes...

    If you overclock in small increments like +3 mhz each time and then when it becomes unstable back of 5mhz you should be safe...

    Since we aren't applying more voltage to the chip we shouldn't be able to kill it; unless it becomes very hot, which is why you should overclock in small increments...
  5. Christufa

    Christufa Newcomer, in training

    yep... 5mhz increments is the way to go. And as for unstable: I start to see white artifacts in game, and eventually about (give or take) 20 minutes after that, my screen just freezes. It usually takes about 15 minutes (blatant guess) before my R8500 core is cooled down enough again to go into a heavy RTCW/MOH-AA bout without crashing.

    Oh, and I have a compusa warranty on the card, so I have a backup plan if ever there's a problem.... I suggest any n00bie overclocker has a backup plan as well.

    btw per hanson, read ur email m8.

    ...so how much does the performance improve by?

    +1mhz = +10 fps ? :D

    I'm just curious if it's worth the trouble. :)
  7. Christufa

    Christufa Newcomer, in training

    in my experience, depends on the game.

    but +1mhz = +10 fps is wrong. Wayyy less than that. And heck, if you're getting great fps in games now, then there's no reason to overclock & risk ruining your vidcard.


    (I for one started doing it because R8500 still sucks for Unreal Tournament in the frame rate department imo)
  8. Whack0

    Whack0 Newcomer, in training Posts: 169

    Yes, i know. It was just a "blatant guess." :D
    Yes, same reason here. What's the frame rate you have now? Fortunately, the next Unreal Engine will run much better (supposedly).
  9. Christufa

    Christufa Newcomer, in training

    uhh.. it improves it a little bit. But UT is much more CPU based than graphics card based. (it was meant for fast CPUs so it could still run in software rendering mode I think).


    Oh, and yes... Unreal 2 will run MUCH better with it. (know this from personal experience, and from reading some anandtech article about the new Unreal Performance test, that's made to test all the newest video cards using the Unreal 2/UT2 engine)

    Build by ATI Radeon 8500 stable without extra cooling at 290/290. Had an increase of 200 marks in 2001 SE.

    Because my system crashed during 295/295 and 292/292, I kind of broke it. I couldn't see any webpage anymore and there were visual artefacts on my windows screen.

    I cannot state with certity what the cause was. My guess is the system crash (had the same problem once before), but it could be the new drivers or the overclocking.

    Well... some guys at madonion have gotten their radeon's up to 300/300 with extreme cooling, but as far as i've heard, it only lasts through the bench as it begins to build up temp so fast that even the water cooling can't cool it... so i'd say 290/290 should be ok for watercooling

    Radeon 8500

    I have the retail 275/275 card. I have overclocked to 290/290 using powerstrip with no issues using standard cooling on the card and three case fans. I was able to get a 3dmark2001 score of 8144 with the 6043 drivers with no overclocking and 8367 with overclocking.

    So how did you install the 6043 drivers? I read the threads at Rage3D and they say to...

    1. Uninstall the old driver
    2. Reboot
    3. Start RegCleaner, check Ati Technologies - Cbt, Cds, Desktop, (leave intact - if exist - MMC, Sushi Engine, HydraVision, Multimedia), click on 'Remove Selected'
    --another person said to remove all, including MMC, Sushi Engine, HydraVision, and Multimedia
    4. Reboot
    5. Cancel stupid MS HW Wizard and install 6043
    6. Reboot
    7. Enjoy!

    Some of the people there couldn't start Windows after the drivers.... I don't like the sound of that. But overall, they say it's the best drivers yet for the 8500.

    So how did you install the drivers?

    Ati is not a good driver developer, nvidia is though
  16. Christufa

    Christufa Newcomer, in training

    That's pretty much how I installed them. And they're LEAKED so they're not supposed to be easy to install. If you don't install it this way, not all of the OpenGL changes take effect (performance gains), and software from the old drivers will remain. If they were an easy executable, even more people would use these leaked drivers, so they just leave it as is (blatant guess :p).
  17. Christufa

    Christufa Newcomer, in training

    oh... forgot to add.

    They definitely sped up Open GL in a couple games that I play, but not the supposive 40% that's being told in the threads....

    prolly closer to 5% in RTCW.... not tested yet in MOH-AA though.

    man... what would it be like if ATI had released the R8500 with drivers like they have now.... they'd be in such good shape instead of trailing the GF3Ti500 in sales.
  18. Federelli

    Federelli Newcomer, in training Posts: 382

    haha it'd be nice to see a 40% performance increase when each driver is released, woudln't it?

    why are drivers such a pain to install and uninstall?

    Federelli Newcomer, in training Posts: 382

    in the butt? cuz companies don't gice too much about drivers being suuuper cool... they just make sure that one set of drivers is good enough to give them "propaganda"
  21. Whack0

    Whack0 Newcomer, in training Posts: 169

    So what did you do for step 3? Did you use RegCleaner to remove ONLY Cbt, Cds, and Desktop? Or did you remove ALL (Cbt, Cds, Desktop, MMC, Sushi Engine, HydraVision, Multimedia)?

    ...I'll blatantly guess "ALL"... :p

    oopsie

    Sorry bout the curses

    Anyway, seems to me even with official drivers it never completely uninstall itself. Not even Nvidia do a nice job on the uninstall, just surprising cause you'd think so many people have complained about this.

    On the "how to install the drivers" remove everything; It will be replaced by the new(er) drivers anyway...

    And about the 40% improvement; That can be true because there has been a bug in MOH:AA which caused that slow down on the "snow level" ...so perhaps they fixed that and used some "nice wording" ;)

    This is true Federelli, but it seems as though ATI might be picking up their slack. Plus, their cards seem to come with extra goodies and cost a little less. Nvidia needs to get on the ball with the GeForce 4's and get some serious performance out of them, else they'll really have ATI to deal with.

    I have a quick question regarding the overclocking of the Radeon (not sure how to word it, but here goes):

    Does overclocking the Radeon (or anything else for that matter) decrease the "lifetime" of the card? ...Will it go "bad" faster than not overclocking it? ....Does it wear the card out faster?

    ...Get what I'm asking?
