bodiebill Posted August 18, 2019 Share Posted August 18, 2019 My setup is now with 3 PC's: (1) Windows Server 2019 which connects to my NAS music library (still unoptimized) => (2) Audiolinux with HQPlayer 4 embedded (still trial) => (3) Audiolinux or Euphony with NAA (also still trial) I also have Audirvana on (1) which sees the HQPe, so wondered: would it be possible to decrease the load on (2) by using Audirvana to upsample to, say, DSD128 or DSD256, to hopefully reduce stuttering playback of DSD256 with ASDM7EC? Of course I tried, and I have the impression that the stuttering is somewhat less, but it is still there. Did anyone here try something along those lines? Does it make any sense at all? audio system Link to comment

I cannot emphasize enough - do not use ethernet cables that have a shield connected to connector bodies at both ends. So typical STP/FTP cables are absolutely no-go for NAA. I use standard cheap CAT6 UTP cables (entire house is wired with CAT6 UTP). Glass fiber cable for Ethernet is also a good option I guess? audio system Link to comment
bodiebill Posted August 29, 2019 Share Posted August 29, 2019 I just got a license for HQP embedded, and am ready to build something to enable playback of DSD256 with EC. Something along the lines of: case Cooler Master Elite 110 mobo ASRock Z390 Phantom Gaming ITX cpu Intel Core i7-7900K (TDP 95W) cooling stock? memory 16GB RAM 2x8 PSU internal HDPlex 250W ATX PSU (accepts 19V) PSU external HDPlex 100W LPSU 19V + 12V Would this be a good idea? Will the HDPlex 100W LPSU be able to cope? (I am planning to use a separate 12V rail for the CPU.) audio system Link to comment
bodiebill Posted August 29, 2019 Share Posted August 29, 2019 Thanks! So my main concern before ordering is: Will the HDPlex 100W LPSU be able to cope with this 'gaming rig'? audio system Link to comment

That's the main concern. 100W sounds low, I think my PC wanted a 400W supply and I went 750W. Randy Thanks, that is a handy tool. It shows that I would need 239W. I would use this machine only as a server with HQP OS or AudioLinux with HQP embedded, sending the DSD256 files to a minimal fanless NAA PC in the audio room over fiber ethernet. Would a linear PSU make much difference in that case, SQ wise? audio system Link to comment

That's what I would use for both safety and SQ reasons. Thanks. I already have: (1) HDPlex 100W LPSU (2) HDPlex 200W LPSU (3) HDPlex 250W DC-ATX converter and hope to avoid having to buy a 4th HDPlex PSU... My current diskless i7-3770S 3.10GHz PC with AL and HQP embedded was for a long time powered with (1)'s 12V rail and that always seemed OK. Perhaps, for the new PC, I will try (2)'s 12V rail for the CPU and its 19V rail feeding into (3) for the rest, and see how it goes without CUDA. Or I could even try (2) for the CPU and (1) for the rest, so that both PSU's would share the load, effectively creating a 300W LPSU. audio system Link to comment
bodiebill Posted September 14, 2019 Share Posted September 14, 2019 I received an email from HDPlex's Larry over a week ago in which he told me to expect a new batch of the 400W ATX converter mid September, at least for Europe. You could drop him a line? audio system Link to comment

Running buster 10.1 with 4.11.2-36. No graphics card so no cuda offload Any tricks to get 7ec? Thinking about trying to overclock, I feel like its really close to working. Just in case: I assume you have turbo boost & hyperthreading enabled in BIOS? Here 7EC plays stutterless with the exact same CPU without overclocking or CUDA offload. audio system Link to comment
bodiebill Posted November 19, 2019 Share Posted November 19, 2019 I had the same: last week: when I changed from AL to HQP OS the fingerprint changed. Looking at ifconfig I assumed it is because HQP bridges my two Ethernet interfaces and AL does not. audio system Link to comment

It is likely something else. Ah, wonder what it could be then. My motherboard came with two stock NIC's to which I added an Intel card with two fiber NICs. Anything to do with that? audio system Link to comment

I guess the safest bet is just to go with I9-9900K Here I7-9700K with 16GB RAM and no BIOS tweaking, just turbo mode, works flawless with EC7 and DSD256.

bodiebill Posted December 21, 2019 Share Posted December 21, 2019 My setup: Audiolinux headless with HQPlayer embedded latest version ASRock Z390M-ITX/AC i7-7900K 1x Apacer DDR4 RAM 2666MHz 8GB (non-ECC) Since putting in the Apacer RAM I get occasional tiny dropouts when upsampling to DSD256 with ASDM7EC. I never had these before using hyperthreading and turbo mode without overclocking. I just reset the BIOS to the optimal settings and at first that seemed better, but now the occasional dropouts are back. I will try to put in a second RAM (8GB => 16GB) and see if that helps, but I expect not as 8GB should be sufficient for HQPlayer? Any advice? audio system Link to comment
bodiebill Posted December 22, 2019 Share Posted December 22, 2019 Doubling RAM 8GB => 16GB did not help. The dropouts even occur when upsampling to only DSD128. Also, they are unlike the dropouts I experienced with EC7 upsampling to DSD256 when my system was not yet powerful enough. As I upgraded to HQPlayer version 4.13 at the same time as I put in the Apacer RAM: could it be a problem with version 4.13? audio system Link to comment
bodiebill Posted December 22, 2019 Share Posted December 22, 2019 So i went back from AL + HQP 4.13 to Jussi's 4.12 image. Still tiny dropouts with ASDM7EC / DSD256 😐 So what now? Should I try to overclock? I have no experience with that. Can anyone advise how to do this for an ASRock Z390M-ITX/AC motherboard? audio system Link to comment
bodiebill Posted December 22, 2019 Share Posted December 22, 2019 Apologies if I am talking to myself, but it seems that subtle overclocking did the trick. The only setting I changed in the ASRock Z390M UEFI BIOS was going from Load-Line Calibration level 4 to level 3. This applies additional voltage to the CPU under load to provide more stability. Fingers crossed... audio system Link to comment

Using HQP OS is what fixed it for me. Just upgraded to the newer version, still working fine. Perhaps, but I am somewhat puzzled as the dropouts are tiny and only occur after 40 seconds or so. And they also occur with dsd128 and temperatures remain moderate (<60C). So I suspect it is something else. audio system Link to comment
bodiebill Posted December 24, 2019 Share Posted December 24, 2019 13 hours ago, Miska said: What kind of CAS latency does this memory have compared to earlier one? Both configurations with 4 memory modules? This CPU requires that it is running at high enough boost clocks for the relevant cores in order to perform ASDM7EC successfully. What kind of filter are you using? One module of Apacer DDR4 RAM 2666MHz 8GB. Also tried two modules but that did not remove the dropouts. I believe CAS latency is 19 and the Ballistix I used earlier has lower CL. Could that be it? Filter used is poly-sinc-ext2. I did get rid of the dropouts by going from Load-Line Calibration level 4 to level 3 in the BIOS (ASRock Z390M-ITX/AC). This applies more voltage. I did not increase the CPU frequency, so I am not sure whether one would consider my tweak as overclocking. audio system Link to comment
