<div class="gmail_quote"><div>16x PCIe 1.0 should be plenty fast enough.</div><div><br></div><div>I did see some comments in one of the other threads mentioned above that suggested that heat may be an issue. Apparently the cards will clock down when they get hot. Because you seemed to suggest at one point that the issue appeared resolved, then came back after an hour of use, you might just check to see how hot the card is getting.<br>

Used to be an AMD x2 and I upgraded it to a full blown Intel Xeon server (Supermicro X9SRA). I am using the same GT 430 graphics card as I had in the old machine. I used to be able to use the High Quality Nvidia VDPAU without any problems. I had smooth video no matter what the broadcast with Adv 2x with a Adv 1x fallback (never tried 1080p). However, now when I try to use any VDPAU even without deinterlacing filters the video is a lot of push-pull/slow-go to the point of being annoying. It's especially noticeable when there's a smooth pan happening in the video or if someone is walking across the screen. I'm currently doing all the decoding on the Xeon processor instead of using VDPAU because of this. I still need to try realtime threads...</div>
<div><br></div></div></blockquote></div>The GPU specs say it's maximum temperature is 98 C... I'm sure the thermal protection kicks in a few degrees under that. A quick google search says "like 90C"... but that's just a user complaining about the card.<div>
<br></div><div>I would start by forcing as much cool air onto the card as possible and see if the problem goes away. A 12" desk fan on high will usually do it. If it works, then you need to do something about your airflow in your case.</div>
