Thanks for your suggestions.
I think I have got to the bottom of the problem - My RAM was not liking the default Voltage assigned by the BIOS.
I upped it to 2.2 Volts (which is implied within the SPD when running dual channel) and lo and behold, the board now seems stable on the DVI port.
It's been playing Shooter (HD-DVD) for two hours now and not so much as a blip.
This is encouraging, as I've owned this board for two weeks and I was beginning to get disheartened by this problem. My previous rig was based on the previous Nvidia chipset, namely the NF77. This was running an intel CPU, and was quite simply a crap chipset. It was 7150 graphics core, which compares poorly compared to the 8200.
The main drawbacks with the 7150 that the 8200 solves are:
1. no purevideo support.
2. HDCP does not work properly as the key is stored in the BIOS not in hardware.
3. No DX10 support.
4. Single channel memory only
5. Network card did not work unless ram clocked back to DDR2-667
So as you might guess, my Geforce 7150 HTPC was far from perfect. I ended up adding a cheap 20 pound HD2400 to finish it off.
My plan was to create a super low power Blu-Ray/HD-DVD machine that sucked less than 60 watts total, with no discrete GPU.
The 7150 machine did work in the end, but needed an intel core2 duo E8400 at 60 watts TDP to do the video decode smoothly. It also needed AnyDVD to workaround the HDCP issue.
The 8200 is so much better, now that the Purevideo HD engine is offloading the Video decoding, I need a less powerful CPU to do the remaining work.
Like most people on this forum, I chose the 4850e. It's nothing special in itself, basically the same as a 4800+ in terms of performance.
What is special is that it runs at 45 watts and although the intel chips may have best bang for clockrate, the 4850e definitiely leads the way in terms of bang for power.
So in summary I do think this 8200/730i platform is great. My first HTPC with no discrete GPU! And the Blu-Ray/HD-DVD use case is fully covered.
The only real downside of the Asus 8200 implementation I have found is not with the Mobo itself, but more to do with AMD's current CPU lineup.
The 4850e is rightly the CPU of choice for the 8200, however, this chip is only AM2 and therefore cannot leverage the faster HT link of AM2+
Anyone know if AMD plan to come out with a 45 watt 4 core Phenom, running on AM2+..
Or am I dreaming on that one?
