CrashX Wrote:That really shouldn't matter much .. Yes Dual channel is alot faster but single channel should be more than enough for 720P playback ..

However as Haggy pointed out others HAVE solved problems by going dual channel with IGP solutions. Folks don't throw out these suggestions just for fun generally - really! Rolleyes

My config is:

What bitrate "720P"? Resolution is less of an issue than bitrate. You can run 1080 Apple Trailers and be fine but then try Killa' and crash. Both might be "1080" but wow what a difference bitrate makes. 720 is easier but say playing 1080 and putting it on a 720P screen for instance will likely take more CPU. You have to be concise...

My config is:

Amd athlon 3500+ (2.2 ghz single core if i'm correct)
1gb (2x512 mb crossair ddr [yes.. ddr1])
Gefore 6800GT AGP 128mb
1tb Sata-II wd disc (for media)
20gb Ide wd disc (for ubuntu + xbmc)

I never had ANY framedrops. I also didn't change much from the default ubuntu config.

Are you running any other applications? Maybe your hard-drive can't keep up with the datastream while running other applications like bittorrent for instance. But on a clean install XBMC should be running fine on most avarage systems in my findings....

Well I have thought about this to, but its not like the torrents are uploading very fast, and they are often not more then 2-4.

Can this really be ok, with only 45 MB left of the RAM?

This is linux - it actually USES available RAM unlike windows. Please look at output of 'free -tm' to actually see what is used and needed.

Is this ok? So you dont think my "lack" och RAM is what causing my drops?

Also, you mention that you are running bittorrent in the background. What client are you using? Because Azureus (now Vuze, I guess), for example, is a cpu hog. And since you're not using vdpau, you're completely reliant on the cpu to decode. Combine that with a (relatively) weak cpu, and that could be the source of your skips.

Or maybe it's something else entirely.

Im not running Torrents on the HTPC, only over the network, from my other PC. So using samba and saves on the HTPC.

There is a thread about memory type concerns. A non-concern. Just the way Linux managed memory. Search and you will find the thread I am talking about.

Thanks.

I run 2gig on two different systems and one of those is running bittorrent to the same drive XBMC reads from using Transmission on the same box. Zero issues with memory or video playback. As others have said - 2gig is plenty. You're using AEON, I'm using PM3 HD, only real big difference. <shrug>

Well Aeon, or Mediastream, I got the drops anyway.

You got 732MB available for apps. 676MB are i/o cache from the kernel which get freed if needed. As tslayer said: This is the way linux USES (write that in capitals) memory.

I usually only have 50MB of free physical ram while running XBMC. Linux caches fill up most of the available RAM, as stated before. It's a non-issue so don't worry about it. Might as well use that free RAM for something, so it's actually a desirable thing.

Code:
$ free -tm
