Miska Posted May 22, 2016 Share Posted May 22, 2016 I think Miska told us there is no sense to experiment with RAMs... Using RAMdisk means having the stuff loaded in RAM at least twice. If it helps - good, but I don't know why... Using RAMdisk increases memory pressure, so you need to have more RAM to avoid swap. I have swap disabled on my machines (except on OS X where I don't know where/how to control that). Signalyst - Developer of HQPlayer Pulse & Fidelity - Software Defined Amplifiers Link to comment

Jud Posted May 22, 2016 Share Posted May 22, 2016 What is 'swap'? Disk space used to supplement RAM. Much slower than RAM, which I assume is why Miska has disabled it.

ColtMrFire Posted May 22, 2016 Share Posted May 22, 2016 Disk space used to supplement RAM. Much slower than RAM, which I assume is why Miska has disabled it. Interesting... Based on this information, I just reduced the size of the RAMDisk drive where I had my music stored, because I noticed RAM was using 92% in task manager. It now only uses about 43% and I swear the sound quality jumped a couple notches again! Link to comment
ColtMrFire Posted May 22, 2016 Share Posted May 22, 2016 I'm not the most computer savvy. I have 8gb of RAM on my laptop/music server. Does anyone know how I would go about upgrading? Let's say I want 16bg total, does that mean I add 8gb, or do I need to take out the RAM that is already in there, and replace it with a 16gb? Link to comment

No. Edit: Or at least Miska says using a RAMDisk doesn't help as far as he can tell. If you want to buy and install more RAM to experiment, have at it.

EuroDriver Posted May 22, 2016 Share Posted May 22, 2016 I'll do some research. Would adding RAM help SQ with HQPlayer? Especially in conjuction with RAMDisk? Using Ramdisk can help in some circumstances, but can hurt in others. The reality is that RAM is a source of noise, it does get refreshed all the time, so the general trend is the less you use, the better. Closely related to RAM noise, is noise which OS activity is generating. Here careful building of the OS delivers considerable sound quality dividends.

They're Ubuntu with different interfaces and different choices for suites of apps, but much of the same "plumbing."

ColtMrFire Posted May 23, 2016 Share Posted May 23, 2016 I just tried running HQPlayer with just the laptop's battery as a power source (until I get better power options) but it starts skipping horribly. What could be the issue here? Link to comment
