Issues with Palit GTX570 - 2011/11/14 16:08
Hello,
been fighting with my card for the last few days.As usual , when i get NVIDIA card , which wasn't the case in the last 2 years, i come to mvktech to get the latest version of nibitor. Ok so far so good. I chose my voltage and frequency safely based on the other posts. So i started 1.088v at 830/2000. Everything seemed fine until , 30 minutes of gameplay. The card suddenly started artifacting.I went to try some Furmark with safety disabled and it was fine . No artifacts whatsoever. Got back to my game and 5 minutes later artifacts again. Decided its the cooling, modified the fan to 100% and started playing. Again artifacts after a few minutes. This time i continued to play and interesting thing is , when i switched maps the artifacts were gone for sometime, then appear, then gone, then appear and so on.So i started tweaking, reinstalling drivers and so on.Nothing helped still the same issue. I moved around the net and found about the powermanagement option in drivers. So i pushed to performance mode, and this time it was better i was getting some occasional freezes for several seconds from time to time. These are now gone.Unfortunately the artifacts are sitll there. Testing with Furmark, or other tools will sometime start with artifacts, then stopping and starting it removes them and it can be allday stable after that.However , while playing this is not the case. I traced this to the voltage modes change on the card. Seems like , when it goes to 3d low power mode it pushes some artifacts.Then it goes back to performance and all is fine for a few min. i have checked on Afterburner and it is indeed showing decrease in load on the GPU from time to time. This leads me to believe my issue is coming from there. So my question is. Is there a way to disable the lower mode. I guess it should be something like changing the right clocks , but i have only the info for the 3d performance. I can see some of the boxes that need to be changed, but i wan't to ask , which one exactly i need to change in order to set high frequency for the lower 3d mode.My assumption is that the card is not performing as expected, because of the drivers and the OS. I am using Server 2008 R2 and i guess Nvidia drivers are not performing as they should on this OS, hence i am forced to tweak the lower mode to the same frequency and voltage as the performance mode in order for the card to perform normally. Also saw a topic that the card has almost the same behavior under XP X64, however the guy was using rendering software instead of gaming, not that it matters.

NiBiTor v6.06
Memory however is a no go anymore, so i have to stay stock there . Anything past 1930 and i am all over the place.I guess there is some difference in the timings, but anyway. I have settled with 880/1900 at 1.1v .Now i have another small problem which is maybe related to the 2D clocks. So i will be happy for suggestions here. I have set the voltage to 0.863 on the 2D , because i want some powersaving during idle, PC is idle 80+% of the time.However , when i watch a flash, or some movie and decide to FF ,or REW the driver will sometimes recover. So my guess is, either the voltage for 2D is too low, or the voltage gap between performance 3D and 2D is too high. We are talking over 2 volts. With voltage set to 0.863 the current sometimes drops as low as 8-9A, which is very good for power saving. Also i didn't notice any other issues except this. My question is, if the card is going directly from 2D to 3D performance on request, or is it moving past lower 3D first. If its the second there may be a solution otherwise i will have to raise the 2D for stability.
