Hexatope Posted June 21, 2020 Share Posted June 21, 2020 Hello all! Some backstory; I've tinkered around with ubuntu builds of linux here and there, tried running SL (Firestorm viewer) on it a few times over the years but never decided to seriously start using it as a primary OS until about a few weeks ago. I have a few other systems so I've been using ZorinOS 15.2 (based on Ubuntu 18.04) and I've been enjoying it quite a lot. I have two desktop rigs, one's all AMD (R5 3600 / 16GB DDR4-3200 / Vega 64, using RADV/Kisak-Mesa 20.1.1) and the other is Intel/Nvidia (3570K, 16GB DDR3-1333, GTX 980 Ti, on Nvidia 440.82 Open Source drivers). I was using the AMD rig for Windows and the Intel one for linux and noticed that Intel was using approximately twice the amount of RAM (as reported by the System Monitor application under memory) when logged into another account in the same area. I initially thought this was an issue with linux, but after trying Zorin on the AMD machine it doesn't have this issue, using up half the memory as the intel/nvidia. Earlier today I set up a 3rd desktop to test performance for a friend looking for some upgrades for his wife's computer, (Fx8350, 8GB DDR3, GTX 960) and noticed that it was also using twice the amount of RAM as my main AMD system. Curiously, I dug out an old Radeon HD 6950 just to see if it would still have this problem on that card. In the area I was in, consumption on the FX rig went from around 3GB of ram down to around 900MB or so. (Performance also suffered but that's to be expected with Terascale cards and OpenGL, not to mention the open source Caiman drivers.) Can anyone advise me on if there's a setting I should change, maybe on the nvidia settings, or could someone test on their machine with other generations of Nvidia GPUs to see if they experience the same? I currently only have the two Maxwell cards, 960 2GB and 980 Ti 6GB, and I'm curious to see if Pascal or Turing have the same problem. Any help would be greatly appreciated, I tried searching around but haven't seen anyone post about this. Thanks in advance! Link to comment Share on other sites More sharing options...
