3  Ultimate Audio Playback / Your thoughts about the Sound Quality / Re: Setting CPU core count with a twist on: January 24, 2020, 07:56:07 am
Peter, All,

I have come across some settings that have a really significant and generally posertive impact on sound quality. Might even be a candidate to look into / exploit in 2.11.

It relates to varing the number of active CPUs set in BIOS. Its well documented that the number of CPUs cores set active in BIOS can be used to tune sound, particually the case for 621 chipset montherboards.

The following simple additional step to core setting really supercharges the effect, certainly on a 621 motherboard which is what i'm using here at the moment.

There are two steps:

1) set the BIOS to a desired number of processors cores and tell XX/OS software that this has been done via reboots into XX un-minimised full OS mode. Nothing new at all in this step.

2) now add a futher processor core in BIOS setting but do NOT tell XX/OS sofware that this extra processor has been added by NOT doing the reboots into full OS mode.


To explain the the setting applied by the steps in a little more detail


Step 1)

Go into BIOS and set a number of active processors. The number of cores you select has to be at least 1 processor core less than the maximum for the CPU. So in my case with a 16 core 6130 cpu, for step 1) I can set the number of CPU cores  anywhere upto 15 for this first step. After setting the cores in BIOS, reboot XX / OS back to XX unminimised level so that the OS / XX recognizes the new number of cores that have been set by the BIOS. Now go back into XX minimised OS ready to play music as normal. All this is just the normal approach to changing the number of cores used be the PC for XX music playback.

Its a good idea to play some music now just to listen to how this sounds before the next step is applied just so that you can appreciate the change the step 2) brings.


Step 2)

This is the extra step. Now go back into BIOS and add one extra core to the number set in step 1). In my case with my 6130 set in step 1 to 15 cores I now set the core count to 16 in bios, save this and reboot. (The key here is just play immediately dont go through the reboots to tell XX and the OS of the change to add this extra core).

Now listen again.

Having applied this, in my system everything tightens up throughout the spectrum, highs are particually improved with real shimmer and sparkle. Speed and dynamics are excellent and the "realness" level of the music takes a nice step forwards. Its not a subtle change.

So far I have tried the setting with 15 cores in step 1) and 1 additional core added by step 2). I won't go into the detail of why but I suspect other combinations such as 10 cores step 1) and 1 core step 2) etc will also produce a similar effect, but as long as its just 1 additional core added in step 2) I think this should work.

It would be interesting to hear what people make of this way of setting cores.

Best regards,

Nick.

Curious as to what is happening here, after step 2 Windows sees all the cores again so nothing different as far as Windows is concerned (Windows always boots to what is set in bios). Maybe XX 2.10 runs differently I don't know.

Anyway my test will be to Unminimize OS & minimize it again without changing bios and hear if sound quality changes/gets worst.

Hi Peter

For me its nothing to do with format change, it happens with all tracks in the playlist are same format.

Hi Peter

I have this problem, the last track stops playing prematurely. This is with SFS=4. I have reduced to SFS=2 to cure the problem. But sound quality not so good. Any news on 2.11 to fix the problem.

Regards
Colin

Hello Zheng - Happy New Year indeed !

I solved this a few days ago. All you now have to do is wait for the new version. Wink

Btw, I think it is not commonly known by others which recognize the issue as "the last track in the playlist", that this happens at a "Format Change". So in the middle of the playlist it can happen just the same, if only a next track is of another Sampling Rate than the current one. The current one now will cut (and for how much depends on the SFS).

Kind regards,
Peter

Most of Kate Bushes albums are now available on Tidal. The ones I've downlaoded so far are MQA44 but presumably benefit from deblurring even though they don't unfold to higher bit rate, I haven't compared sound quality yet.

For non Tidal subscribers they have been available to buy for a while :-

Pictures showing now did not have to do Ctl-F5. Perhaps the browser auto refreshed.

Hi Peter

For example there are no pictures in any of the remote control tutorial pages.

I noticed that * needed in artist name yesterday. Previous Tidal download was a week ago and did not need * then.

10  Ultimate Audio Playback / XXHighEnd PC / Re: Phasure Mach III Audio PC with Linear Power Supply on: March 03, 2019, 05:28:27 pm
MachIII Ethernet Speed:-
With my old PC I used a router ethernet connected to Audio PC to get RDC remote control. The router would not connect via ethernet with MachIII. On Peters advice I solved this problem by using Music PC to make RDC connection to MachIII and another RDC connection via wifi with the router to remote control. This works fine and only one ethernet connection to Mach III needed this way.
Subsequently I found out why router would not connect to MachIII. MachIII will only ethernet connect to 1G/s capable devices and my router was 100K/s max. So if you can't make an ethernet connection with your MachIII this could be the reason.

Bitdefender quarantined ChangeWP.exe as malware.
Restored it and working now.

Thanks

12  Ultimate Audio Playback / XXHighEnd Support / XXHE Startup error on: December 18, 2018, 10:32:10 am
My copy of XXHE which connects to internet for Tidal downloads returns error message (see attached) during startup.

Tried a previous preset but get same error.

2.10 on up to date W10. 17134.471

Only change since it worked was update KB4471324 installed itself.

You don't need to convert FLAC to WAV.
XXHE will play FLAC, converting it automatically when you press PLAY.

Hi Peter

Its:- Custom Filter 352800 low (NOS)

It happens on peaks in music. Also on 0dB sine test tone, switch your amps off first if you try this.

Not particularly a problem, I posted this in case others are using 0dB & get cracks.

Colin

I got Crack Detect occurring recently but discovered my volume was 0dB in XXHE. Went back to my normal -3dB and no more Crack.
0dB with upsampling filters can cause Cracks, I think it was mentioned on the forum a while ago.
