Laptop specs

I use Ubunutu Studio for audio - Rosegarden, Hydrogen, AMSynth, Alsamodular synth, audacity, time machine, zynaddsynth etc - on an 8 year old laptop. I am having overheating problems and want to upgrade to a new machine. Any advice for minimum specs to be looking outfor. E.g. is a 7200rpm hard drive necessary? Should I go for dual core? Trying to spend around £300. Thanks

IIRC there's much better temperature control in recent releases. Alas, it screws up other things on my system, so I disabled it and have to avoid using power-hungry apps for very long. :( Also, what CPU is in your laptop ?

Trying to spend around £300. Thanks I upgraded my Dell XPS M1210 laptop to a 7200RPM drive and resolved my xruns problems. You can get them (the laptop) for under $500 on eBay. They have the Ricoh firewire chipset which used to be troublesome for the FFADO firewire driver. However, under Fedora/CCRMA I've had zero problems. YMMV. -Scott _______________________________________________ Linux-audio-user mailing list Linux-audio-user@... http://lists.linuxaudio.org/mailman/listinfo/linux-audio-user |

7200RPM is absolutely necessary to be rid of that bottleneck, first and foremost. A 5400RPM imposes a practical limit to the minimum size of the buffer, and from experience this can be as big as 256 (meaning anything lower you get xruns regardless of how good your audio interface is). WD has a 320GB 7200 mobile disk going for around 100 bucks. Secondly, the CPU. This is important because the lower the latency, the harder the CPU works. As such, if the headroom is not big enough, you find that even a little bit more CPU usage deals a heavy blow. I'd recommend at least a 1.8GHz Core 2 Duo, which is pretty standard these days.
Overheating is an inherent hardware problem that comes with age. I bet your battery capacity has decreased as well. And a 7200RPM disk will output more heat, so get a flatbed cooler if the laptop's underside design isn't good enough to compensate.

Might also find it worthwhile to open the laptop up and see about cleaning anything that might be obstructing airflow. Just in case stuff has built up over the years. -- David gnome@... authenticity, honesty, community _______________________________________________ Linux-audio-user mailing list Linux-audio-user@... http://lists.linuxaudio.org/mailman/listinfo/linux-audio-user |

* And don't forget to report back the result so we can conclude it as true :) * Yes, SATA only. So beware.
* Especially dust! If you can get those air pressure cans, they do the job mighty well. If not, battery-powered vacuum. But wait, how would you upgrade your CPU? If the processor in this laptop, like most others, comes as a "module" whereby the CPU and GPU are soldered on, it's definitely going to take more than 300 and may just warrant a new purchase in the end.

Reporting back the results of my attempts to achieve low latency on an older Celeron laptop with a 5400RPM hard drive. > * And don't forget to report back the result so we can conclude it as > true :) Any buffer size smaller than 1024 causes xruns. With my UCA202 USB sound card, that makes 64msec latency the lowest I can get right now.
