Best CPU for hqplayer

[kelvinwsy]

This is what bios options i hv.. What offset for AV512 do i try?

[kelvinwsy]

I will try offset at say 2 to start with keeping all else constant

[kelvinwsy]

Voltage Guardband Scale Factor fr Auto to say 2 ALSO

[kelvinwsy]

[kelvinwsy]

I will run Hqplayer for a while and monitor Temps!

I notice that the "AVX512 disable" is enabled.  Seems logical to conclude that AVX512 is off?

[kelvinwsy]

The default are 1.AUTO 2. Enable 3. Disable

[kelvinwsy]

Oh i shuld disable the disable

[kelvinwsy]

Done it Disable the default option of"Disable"

Playing Dsd256/asm7EC now.. No sound difference.. Let's see the temps after 1/2 hr.. 

My Aio and fan setup cools v well.. Lets see temps later

Funny confusing settings "AVX-512 Disable: enable/disable" :D

 

You'd likely want to disable the disable to try...

 

 

Leave offset at "Auto".

Shouldn't affect sound at all, all the math is the same, just CPU load figures may differ. If you get lower CPU load, but higher temps, it wouldn't be surprising. IOW, you can do more DSP work, but also get higher temps as result.

Tried to run DSD512 ASDM5EC at even 4.5 ghz ... Music Plays at correct speed by stutters every 3 seconds.. at 4.2 ghz 1st 4 corrs/ 4.1 ghz at other 4 cores 

Grandscake/Voltage  Set at AUTO

CPU temps shot up to 36-37 after 1 song

 

I then went the other way 4.0 ghz all cores AV512 in ON Mode Grandscale/Voltage on Auto

Plays very smoothly

 

I will try 5.0 ghz and AV512 on/auto/auto and see if DSD512/EC5 will play NEXT

[kelvinwsy]

I suggest that AV512 will allow lower CPU Clock speed for those who are looking at passive cooling .. If I still cannot run Dsd512/Ec5 or ec7 then this Av512 had No relevance for me.

Esp if at 5 ghz dsd 512/ec does not work then??

Itrelevant outcome?

[kelvinwsy]

At 4 ghz Av512 disable DISABLED DSD256/EC7 20 min Temps v LOW

 

Next is 5.0 ghz 

[kelvinwsy]

Hey it plays Stuttering only sbt 7 secs for just an instant!!  EC5

If i hv a Nvda GPU to iffliad the filters i think Ec5 will play smooth .. I cN still crank it up to 5.1 ghz??

Ec7 next

[kelvinwsy]

No EC7 stutters every 2 secs

No go

AVX-512 will mostly help filters, not as much modulators. So you likely notice biggest difference on filters like poly-sinc-gauss-xl(a) and poly-sinc-ext3. If clock speeds suffer, then modulators will suffer.

 

[kelvinwsy]

I am shutting back to 4.0 ghz all cores with Av512 now ON .. and do longer term rinning temp tests .. 

Bcos EC5 even at DSD512 dies not interest me

Unless someone wants me to try something else

[kelvinwsy]

@Miska U know best.. I will enable Av512 and see if i can run 3.9 ghz.. if so i think passive cooling case is next upgrade for me

[kelvinwsy]

3.9 ghz plays v smooth with DSD256/EC7 at xtr-lp filters

[Miska]

You should leave clocks at default with normal Turbo Boost and see how it goes with/without. Just "Load optimized defaults", select XMP profile and try with AVX-512 on/off.

 

If you need to limit clocks, that's confirmation that AVX-512 limits your achievable clock speeds and means that it doesn't provide as much performance improvement as it could.

 

[kelvinwsy]

Anyway 3.9 ghz SQ sounds thin?? Went back to 4.0 ghz

I can try it but XMP Enabled adds a slight hard edge to SQ. I run at 2400 ghz to sound best

I hv AO3 settings and dont want like "Load Optimized Settings" 

I may try it later

[kelvinwsy]

I remember now it was stuttering a bit at 4.1 ghz 1st 4 cores b4. With AV512 ON 3.9 ghz runs .. does that it shows executionof HQplayer instruction sets is now more 

efficient?

[Miska]

Generally, best performance is "Load optimized defaults" and then select XMP Profile 1 which runs the RAM at full official speed.

 

None of this should affect sound quality, just CPU load. I never noticed any sound quality differences, but for me the most important thing is to maximize amount of DSP operations I can do before running out of CPU/GPU power. That indeed defines sound quality results if it doesn't end up limiting what I can do in DSP.
