Re:XpertVision Radeon HD 2600 PRO, and tweaked BIOS update? - 2007/12/05 22:12I've seen your snapshot with 3DMark06, GPU-Z, etc., and could see the enormous memory clocks you had reached. Nice,but I wonder about the 3DMark06 result. At these clock rates I would have been expected results between 4800 and maybe up to 5000 points. It seems to me, that this benchmark had run with default clock rates. Here are three results of other Radeon HD 2600 XT cards at the same resolution, 4737, 4665 and 4681 points.
If I remember rightly all these cards had a default clock rate of 800/1600MHz. What do you think about? Your 3DMark06 result is 4316 points. Have you ever been using Catalyst Control Overdrive just to compare? Furthermore I could see, that RivaTuner shows the wrong number of shader units. I know that.

Why you just don't look at SM 2.0 and/or SM 3.0 scores? And compare them. My CPU is AMD Sempron and I score about 3797 points at no overclocking. And default clocks of this cards are 800/1400MHz, not 800/1600MHz.

Re:XpertVision Radeon HD 2600 PRO, and tweaked BIOS update? - 2007/12/06 09:08By Unwinder's words, ATI has some kind of bug when setting core clock past 857MHz. AMDGPUClock works because its origin is ATI, and they made workaround for that bug. Great score on that Sempron, but you should exchange it with any Athlon X2. It means a lot for newer games, especially those with advanced AI and/or physics are very CPU intensive.

When it reaches 900MHz overclock in RivaTuner, real clock is maybe 20MHz, and if I keep rasing the RivaTuner slider to 950MHz, real clock goes up. Well I don't say anything anymore except that this sounds to me a problem with RivaTuner... And when you go too far you either get errors or the card just stops. And that is just how it is. If you think you know it all better then I think you have nothing more to look for here. I have tested many cards before and overclocked all of them and I can tell you either you get artifacts, which is really not so good for the card or it just freezes and you have to reboot.

Re:XpertVision Radeon HD 2600 PRO, and tweaked BIOS update? - 2007/12/08 08:33After all the testing. I got my card running stable on 708MHz on the GPU with 1.27V. I am not sure what I am doing wrong. I can go much higher clocks speed up to 839MHz but the card will freeze in about 30 min if I am playing Gears of War. When I downclock the card the time periods beween black screen slowly encreases. Now at 708MHz I haven't had a black screen yet. I am not sure what I can do to keep the card stable at higher clocks. My temperature according to ATITool is around 56-57°C under load when the card is clocked at 708MHz.
I suspect that there is other components on the card that are heating up and thats why I get the black screen. I have tried the 1.3V but I get artifacts and I am scared that if I push the voltage above 1.27V I will damage the chip. If someone has any idea please advice. Thank you for all the input in advance.

As I mentioned now enough times but you don't want to get it, you have a not so good GPU and that is just it. And the proof is there, as you provided. Since a lot of others can do easily 1.3V without any issues when overclocking yours is giving artifacts and those give permanent damage to the components. So once and for all you got a less good GPU and that is just it, nothing more and nothing less.

Re:XpertVision Radeon HD 2600 PRO, and tweaked BIOS update? - 2007/12/10 08:34Just a question for you guys using original XpertVison Radeon HD 2600 XT BIOS in XpertVision Radeon HD 2600 PRO cards, do you have any issues with functionality of outputs on the card? I ask this because Palit and/or XpertVision Radeon HD 2600 PRO has DVI, D-Sub and HDMI output connectors, while the XT has 2x DVI and S-Video output.

Re:XpertVision Radeon HD 2600 PRO, and tweaked BIOS update? - 2007/12/15 06:56What is the power requirement for the Radeon HD 2600 PRO? And is it possible that my power supply is to weak for the card. I am running 480 watt Termaltake and I have an AMD Athlon X2 4200+ dual core. Thank you.

Well the power requirements are very low as it only get's the power via the PCI Express bus so not extra molex that needs to give extra power and that is also somehow limiting the not so good Radeon HD 2600 PRO's cause with some extra power via the 6-pin molex from the power supply this would have made quite a difference, like on the GeForce 8600 series.
