Now I have my NOS1a there is no reason to play inside my DAC anymore, Peter has just nailed it haha  So feeling the need to play about today, I finally got round to changing the main clock on my audio PC's mobo. I did loads of research on this about a year ago and bought parts to make up a higher spec clock but just never got round to applying it. Well it went in today without any problems and the heart of my PC now beats on LifePo4 battery power. Carnot say much about sound quality yet as my little one was in bed when the system went back together, but I can say that sound quality at XX vol of -45db (normally play at -30db) sounded extremely good. Will post more when the vol can be wound up. Fingers crossed for good things. Regards, Nick. |

I've spent this morning listening to the Mobo clock. It's very interesting listening. Mid range and highs have never sounded so good here in fact for clarity detail and tone beautiful is the word I would use. There is a smoothness (in the sense of real instruments and voices) that was not possible to fine with settings before. It's difficult to imagine the sound is coming from a digital recording.
I think the NOS1a is instrumental in letting these changes shine through there is so little (any ?) digital sound to it, so changes upstream just pass through it. Nice....
So now for the steps backwards. Well this is about energy and slam and definition in the bass. I had managed to get a great sound going after a lot of work on settings and tweaks throughout my system. The mobo clock is holding back a little of this energy and slam and bass resolution. My toe is not tapping quite so much at the moment as before. BUT I've heard this balance in the bass before, it was when using the same type of module oscillator I've lashed up the mobo with when working on USB clocks some time ago. It's the same signature in the lows and there was a straight forward fix for that....
So summary not a 100% hit first time, but this was not expected with the clock module used. However a very very significant improvement in SQ, and enough to make it worth working on the bass, but might have to spend some cash on a better clock or mod a 24.5mz clock this is unused at the moment.
Final observation clock multiplier setting in bios has very little impact on sound now. That's possibly pointing at the general way the improved improved master clock may work in the system.
Nick.

Nick, could you post some pictures of your mobo clock? I'm very curious about that... although in the future I'd first like to add a good clock to a PCI usb board... Thanks!

Hi, Quick update. The lash up cheap module clock and LifePo4 battery are out of the PC now. It's been replaced by a spare dexa I modified to work with the motherboard. My little one is in bed again so I've been listening at -60db and it sounds really good, full sound and disconnected from the speakers  defiantly improved on the lash up clock even at these stupid volume levels. Bass so far as I can tell is better but need to turn up the wick to be sure it might be a couple of days before I can do this. Very frustrating..... I think I may have a way to produce clocks for USB, and Mobo with -95db phase noise at 10hz and femto second jitter levels, at significantly lower cost than the dexas. Need to buy some parts and have a play. Fralippo hi, sure will post some pics. Nick. |

Hi,
My opinion ?
This won't be of much use. There's a "million" re-clocks behind the master clock (think "clock tree") and they will determine the final jitter/skew etc. It shouldn't do a thing when the master is better, because it is about the proper timing and that things keep on running.
That's all.

There's a "million" re-clocks behind the master clock (think "clock tree")....
Peter hi, I agree with you there, I am also thinking "clock tree" and also about what this tree "drives". The base frequency for instance is multiplied upto 120 times to generate the cpu clock. If the trunk of this tree is not functioning well for audio, then it is sure that the "branches" are effected at some level. The impact cascades up the tree and is likely to be felt differently in different branches. What is known at the moment is that there is "influance", I simply report that subjectively there is a very large change in sound quality with each of the three clocks listened to so far. Setting aside for now if the change heard is better or worse, the mere fact that there is a big change shows that this clock through some linkage mechanisum is closley coupled to sound quality. We don't yet understand how and why, but it just is. The change is so large it should easy to work out if this a "no brainer" or an interesting diversion. I should get to listen at high volume levels tomorrow so I'll feed back more on sound qualty good bad or mixed however it turns out. Best regards, Nick. |

Hi, Well there has been chance to listen to the Mobo clock upgrade today at normal volume. It doesn’t take two bars of music to realise this upgrade is a forklift sized upgrade to sound quality in my system. The synergy of the modified PC with the NOS1a is just absolutely superb. Let’s not get too hooked on the hows and whys. I have plenty of thoughts about how the clock might be impacting the PC and music reproduction, but this definatly is not one to get too tied up on theory... it just works and how it works !!!  I will post more details of what has happened to sound quality with the Mobo clock upgrade. For now I can say with no doubts at all that the ASrock Extreme 4M mobo has become a device in a different league for playing music.  Nick. ps two more locations in on the Mobo are on the shortlist for treatment |

You f...  Of course I don't believe it until after 5 days of this of several hours you say the same. So that bring a bit of (weeks of) waiting with your children not being used so some SPL. Haha. That there's a difference I will believe upfront. And that it coincidentally can be better, too. For fun : now change the CPU speed and see what happens. Could be a warm surprise ... Btw, what is your net speed at this moment ? I mean, how it shows in TaskManager ? Peter |

My PC systm is running at a processor speed of 430mhz with max of 1.2gb. I'm in quiet time again so cannot try faster cpu just now, however when Itried high cpu clock ratios a couple of days ago sound was more consistent than before. Will give it a go. I'm expecting that faster cpu may be possible with good sound.
Thought a pic of the PC might be fun. Poor thing has its guts all over but the SOUND haha
Best,
Nick.
