Re: Strong Artefacts - Questionable SNR and high BER

Thanks both,

Setting "Performance" governor for cpupower did not work and I think that was because of boost was still enabled. I have disabled the following in the bios and it now works!:
AMD Powernow
AMD CPB
CPU C1E
CPU C6

Thank you for the hints.

Re: TVHeadend + xbmc strong artifacts

For me I find putting the CPU under stress actually fixes the problem. I don't understand how this fixes the problem for me but try: "stress -c 1" TBS, Any idea where the problem might be? Could it be the "Relaxed Ordering Bit" PCI setting? Disabling CPU frequency changes does no...

TBS,

Any idea where the problem might be? Disabling CPU frequency changes does not help.

Re: Strong Artefacts - Questionable SNR and high BER

Are TBS planning to investigate this at all? It affects quite a few motherboards. I've tried my 6985 on 2 mnotherboards and it does not work properly on either. The same boards work fine with a mixture of other cards in cluding another TV tuner. Can TBS swap my 6985 for a 6984?

Re: Strong Artefacts - Questionable SNR and high BER

Just wanted to add my experiences to this thread. I tried initially with a Tyan S5512 but this could not detect the 6985 at all, then bought an Asus KCMR-D12 which detects the card fine but I had severe artifacting for HD and regular artfacting for SD when using just one tuner. Then applied the patc...
