Just want to let you know my testing on using some old used Xeon to play around hqp DSD512 with poly_sinc_xtr_mp. The test run with new instsalled Win10 Pro with no optimizers yet, to a winsvr 2016 NUC NAA and T+A DAC8 DSD. 1) Xeon e5-2670 C1 (8C16T) + X79 + DDR1333 ECC 4G x4 2s okay, non-2s not ok 2) Xeon e5-2660 v2 (10C20T) + X79 + DDR1333 ECC 4G x4 2s okay, non-2s not ok 3) Xeon e5-2683 v3 (14C28T) + X99 + DDR2133 8G x2 non-2s ok Set #3 would be a cheap alternative which cost about 35% of new TR set. Hi salaryman, on #3, are you able to provide details on how you achieved non-2s on this hardware? On a similar system (xeon e5-2683v3, MSI X99A SLI Plus, 2x4G G.Skill DDR4-2133, debian stretch 9-5,) I'm not getting anywhere near DSD512 with a non-2s filter. Cheers Link to comment

AudioXP Posted October 29, 2018 Share Posted October 29, 2018 Thanks, salaryman, for your quick answer. @Miska, I'm running the latest HQPe (4.6.1). Tried on both Ubuntu 18.04 and debian 9-5. Results were similar, in that I'm far away from full load on all/any cores. Link to comment
AudioXP Posted October 29, 2018 Share Posted October 29, 2018 I'd be happy if it works within rate families (have auto rate family box checked). Will re-run some tests to produce "top"/"htop" screenshots which I can post. Cheers! Link to comment
AudioXP Posted October 29, 2018 Share Posted October 29, 2018 Also got another 2 4G memory modules coming in, to use all 4 memory channels. Don't expect that will give a big boost, though. Link to comment

Anyone with such a machine and using convolution and matrix please report I have this running DSD256, with convolution, without matrix. Runs all filters except closedform16M. CPU load around 50% average per core. Max temp approx 65 degr C. Edit - my CPU is a 9700K.... Le Concombre Masqué 1 Link to comment
