Gato Posted April 14, 2020 Share Posted April 14, 2020 Hello, With: iMac/Roon->PC machine(i7-7700K, JCAT NET Card FEMTO) / HQPlayer(v 4.3.3) Upsampling to DSD512->USB(SOtM tX-USBexp PCI express USB 3.0 with sCLK-48.0)->ISO REGEN / UltraCap LPS 1-2->T+A DAC8DSD. Since a few month (november - december 2019?), I have the following situation: When I power up the systems and begin to play music everything sound very good but after 2 to 3 hours of listening I can hear random "pop" noise coming out of the speakers. The sound is always good but those random "pop noise" are becoming more and more frequent (first every 3 to 4 minutes and then every 30 to 60 seconds). If I power down the systems wait about 1 or 2 minutes and power them up and play music, those random "pop noise" are still audible. If I power down the systems and come back, for example, the next day and I power on the systems and begin to play music everything sound very good (no "pop" noise) but after 2 to 3 hours of listening I can hear random "pop" noise coming out of the speakers. The sound is always good but those random "pop noise" are becoming more and more frequent. ... And so on. But today after entering in the random "pop noise" phase and without power down the systems, in HQPlayer settings, if I go with "...Upsampling DSD256...", there is no more unpleasant "pop" noise for about 1 to 2 hours of listening and then a "pop* may occur mainly in the 10 first seconds of a track and so on for the next tracks but those "pop" are no more systematic or frequent as before. Any idea / explanation?

I would first try with the motherboard's integrated USB ports (Intel controller) and without REGEN, so just plain standard USB port directly to the DAC. This in order to rule out pops caused by lost or corrupted USB packets. You should always keep this grayed. Also remember to keep HQPlayer volume set to max -3 dBFS and keep eye on the Limited counter that it stays zero (meaning that volume knob doesn't turn red ever). Hello, Oh Yes, indeed, without the ISO Regen, no more "pop noise" at all at this point in time. Now, I will also continu to verify the rest of the hardware used. To be noted, on my system, when upsampling to DSD512, if Multicore DSP is grayed, there is a lot of stuttering. So in this case, for this system, unchecked is OK. Thank you very much for your help!

Please check that you have "High Performance" power profile selected in Control Panel -> Power. Are you using any "system optimizers" (AO, Fidelizer, etc)? The PC in question is a "Windows Server 2019 Standard Core: RAMDISK Network booted using also AudiophileOptimizer and Fidelizer.

Gato Posted April 16, 2020 Share Posted April 16, 2020 5 hours ago, Miska said: Please try without AO and Fidelizer, those could be the source of such stuttering problem. To be noted: my initial issue was due to the "UltraCap LPS 1.2" used to energize the ISO Regen. Using ISO Regen without UltraCap LPS 1.2 eliminates the "pop" problem. Uptone has been contacted about that. For the rest: Upsampling to DSD512 with Multicore DSP Grayed: Without Fidelizer but with AO: Same stuttering Without Fidelizer nor AO: Stuttering but a bit different (light) and with one more kind of noise like a very light frying "crcrcr".

Gato Posted April 17, 2020 Share Posted April 17, 2020 21 hours ago, Miska said: OK, this is wrong. I would recommend to use the "Load optimized defaults" in BIOS to load the default settings and leave it at that. Turbo Boost, Hyper-Threading and Speed-Step/Speed Shift must be enabled. You could as well leave all the C-states enabled, but this doesn't affect performance, only power consumption. With "Fidelizer + AO", Without "Load optimized defaults" in BIOS, But with Turbo Boost, Hyper-Threading, Speed-Step/Speed Shift and all the C-states enabled, no more stuttering when Upsampling to DSD512 with Multicore DSP Grayed. To be noted: I have also "Package c state limit" set to "C8", do you agree with this one? PS: For the rest, ISO REGEN with UltraCap LPS-1.2 switch up to “ON”, there is no "pop noise" anymore.

You could as well leave all the C-states enabled, but this doesn't affect performance, only power consumption. Two more points about that: With "Fidelizer + AO", Without "Load optimized defaults" in BIOS, but with Turbo Boost, Hyper-Threading, Speed-Step/Speed Shift and all the C-states enabled, no more stuttering when Upsampling to DSD512 with Multicore DSP Grayed. BUT with all off that now, when upsampling to poly-sinc-ext2/ASDM7EC/48k x 256 with Multicore DSP Grayed, the sound drop every approximatively 40 sec for one sec. So to successfully Upsample to DSD256 via poly-sinc-ext2/ASDM7EC/48k x 256 with Multicore DSP Grayed, the following do the thing: With "Fidelizer + AO", Without "Load optimized defaults" in BIOS, with Turbo Boost enabled, Hyper-Threading Disabled, Speed-Step/Speed Shift Disabled and all the C-states disabled, no more Drop.
