Hallo,
Nadat ik twee exemplaren van de Asus 9800 XT heb kunnen testen (overklokken
) vallen mij de resultaten nogal erg tegen. De core wil niet verder dan 415MHz, terwijl het geheugen bij mijn eerste exemplaar al op zijn standaardsnelheid artifacts geeft. De core wordt maximaal 65 graden en het geheugen 59 graden. Aan mijn voeding ligt het waarschijnlijk niet aangezien ik een Enermax 350W heb. Wat ik nogal opmerkelijk vond is dat sommige reviewers deze kaart redelijk tot goed konden overklokken, terwijl andere reviewers ongeveer dezelfde slechte resultaten krijgen als ik. Bijvoorbeeld:
Quote Nordic Hardware:
About the 9800 XT results:
Certainly the Radeon 9800 XT has 412 MHz as standard on its core but the fact is that OVERDRIVE is supposed to bring up the core to 432 MHz and from what we have understood that's where ATi draws the line for qualified chips. In that case we can say that GeXCube overclocks 0 % on the core and Sapphire is not so much better. The memory isn't anything nice to work with either when it comes to overclocking.
But our results, especially when it comes to the cards core, are not in conjunction with what we have seen in other reviews out on the world wide web. It seems to be something wrong with our testsystem. We have spoken with the manufacturers and ATi themselves. (since we have the same problems with ATi's reference card). The popular theory is that we have a too weak PSU. We have made more tests with a high quality 450w PSU and it didn't make any difference. Other bids have been the program we have used to overclock but here we have used four different programs (Rage3D Tweaker, PowerStrip, RiveTuner and ASUS SmartDoctor) without any luck with one or the other.
Another explanation people has tried to give us is that we have had OVERDRIVE activated, but that hasn't been the case in any of the tests and which would in any case cause graphical errors and stability issues.
Finally we re-installed Windows, drivers, tried exchanging hardware and everything else you can consider doing in that situation. Concluding: The problems was there no matter how much we tried.
That leaves us with the question: Is there something fundamentally wrong with our testsystem or does the cards just overclock really bad (in other words. are our cards of worse quality the usual ones)?
To be honest we don't really know what it can be. So don't consider our result as anything final when it comes to the three Radeon 9800 XT-cards core-overclocking. The other results we have ended up with seems to be right if comparing to other reviews.

Nou is mijn vraag: tot welke frequenties kunnen jullie je Asus 9800 XT overklokken?
