This is more complicated once you see the relation with XTweaks in XXHighEnd. I guess you do, but just saying ...

with lower speeds the sound gets softer in a way I dont like

Do you mean with CPU underclocking or Ram?

I've tried underclocking Ram and felt it wasn't as good soundwise. This was with the CPU already underclocked. I currently run Ram per default speed.

I've been playing with Xxhighend settings lately so haven't tried Bios settings. I try not to play with too many sound balls in the air so to speak!!!!

CPU. there was a similar effect with RAM underclock only worse, which you also noticed... I wonder where the benefits of higher RAM speeds end, if we should be using the fastest RAM we can get our hands on.

There might be something to undervolting or overvolting RAM, since the last post ive switched to 100mV undervolt instead and this sounds interesting too ... it takes a while to figure out if these small differences are improvements or not, or if a more musical/lush/vibrant sound isnt adding some form of distortion.

If its available to you another setting with some potential could be ''PCH Core'' voltage, which apparently feeds the chipset which handles all the USB, SATA, PCIe communications. It was possible to drop it from 1.0V to its minimum 0.8V, all is stable and AFAICT sound quality has improved slightly.

Thanks for the support on this

I hope this general PC testing is ok to post here, if someone will even find it useful

Its a great idea its an area that needs more work. When I updated Bios last year, it put all settings back to default.

Took me a month to realise. This time I went further and it did make a bigger difference. But I've wondered if I did lose something with lower clock speed as you suggest.

I havn't played with voltages. Online there's heaps on overclocking using voltages for gaming but nothing with regards to music. Keep the good work up.

CPU underclock had more clear benefits than RAM underclock, these benefits were easier to appreciate when other areas of the PC were improved but with lower speeds the sound gets softer in a way I dont like, I think there is an overlap of benefits and negatives, smoother, more natural but lower clock speed reduces energy or ...speed
of the music.

After some more tweaking I think voltage plays a very big part in how the CPU affects sound.
With simple underclocking there must be some undervolting happening too, with minimum 800MHz CPU underclock and ''auto'' setting for core voltage in BIOS, the core voltage reduces to around 0.9V from 1.1V @ 3.5GHz. Only with a fixed core voltage can you hear the actual effect of clock speed on sound.
With manual control it can be set much lower to 0.7V at a maximum 1600MHz, which sounds more vibrant and at least as smooth as 0.9V at 800MHz. I have yet to compare clock speeds at a fixed voltage or the minimum core voltage 0.6V.

The RAM voltage also has a big influence on sound but its very sensitive and not as clear cut, for some reason only slightly overvolting sounded like an improvement, a 50-100mV increase to default 1.2V.

I hope this general PC testing is ok to post here, if someone will even find it useful (other MoBo manufacturers BIOS may do things differently to Asus).

Peter,

In addition to the difference in HF content, there is something about the consensus configuration where the "attack" on notes: piano, drums particularly seems more accurate.  Notable listening to Keith Jarrett on piano.  One album worth using for tests is the incredible "Birds Requiem" by Dhafer Youssef

Btw, Ramesh, it seems evident that the lower dynamics (but this is mere higher frequency stuff) cause the depth to deminish. I am just observing after I read your post ...
Quite similar to adding F-M highs to your Orelo MKII speaker (adds spaciousness).

Regards,
Peter

Robert, I suppose this is the same problem as the Q1 x xQ1 being too high together with the low SFS. This means
a. lower the Q1 x xQ1;
b. I must solve the same problem (somehow).

I suppose this is related to processor speed as well (timing). But not sure ! Just wait until I solved it (hopefully).

Thank you for sharing !!
Peter
