Thanks Peter and Alain. It seems that with my motherboard it is impossible to avoid the fans.

A lttle late reply but relevant for those why might be tempted to try.

Simply put I was trying to use the bios settings to lower and fix the voltages on the Mobo components (cpu, memory, chipset). This resulted in a lower average power consumption and a change in sound.

Now the only consistent result I got was a computer that hangs on one of the future (windows 7) boots or freezes during normal operation. Resetting the voltage to auto fixes the boot/freeze problem. Not a very unnerving problem but this also makes it an unworkable tweak.

I'm not diving into it any further.

cheers, Coen

Hi there,

I saw this PSU tweak popping up in another thread and I already planned to share some notes. This didn't happen until now because I I lacked time and energy and I find it hard to form a consistent opinion.

Following a resolution I made with myself to once experiment with a Linear supply I decided in April to order a HDplex supply and matching 250Watt ATX converter. A sort of hybrid solution that at least in theory could bring some benefits. Expedition was fast and the whole lot looks like a well designed piece of kit and was able to fire up my Audio PC containing two harddisks (see signature).

Like I expected the power consumption at the powerstrip is significantly higher with the LPS, rising from 50Watts to 70Watts with my Win7 setup and 9e. Oddly the XX version 1.168 uses even 10 Watts MORE with (seemingly) identical settings. Consequently these extra 20/30Watts heat up the case.
At a "warm" day (20+ degrees in the room) I found it uncomfortably hot with 1.168 and also SQ seemed to suffer. The transformer started to make a noises (humming). Fortunately my 9e setup did not overheat or overload the box. My conclusion is that your setup should be limited to a 35-40 Watts power draw from the PC.

At the first audition I liked the midrange clarity and increased contrast to use a visual metaphor. Also there was a more natural flow to the music. However highs seemed a touch rough and the lows a little bloated and ill-defined. On closer inspection of my setting some had changed over time and I started to reset all to the settings in my signature. This gave quite a good sound that was different on a few aspects form what I remembered from the ATX switching supply.

In the past few weeks I have been changing settings, SATA connections and other stuff to make it work to my taste. The surface the PSU is placed upon really matters as do the SATA connections. Lately the latter seems less relevant because of the Diskless XXHE PC developments. I think it sounds quite nice now, but feel it has more potential and there are a few more experiments to conduct.

Interestingly at a time I reconnected the Seasonic out of frustration again. The sound was a tad smoother overall with a rough edge on the highs. It obviously lacked dynamics and flow that makes sound sound alive with the lPS. Still the LF and HF lack some focus and definition with the HDPLEX LPSU in comparison with the switcher. So this box is no perfect solution yet but a different balance that is more to my liking, at present.

These are a few observations and opinions on the effect on SQ at my side. For now I prefer the LPS over the Seasonic, but I'm also performing maintenance on my speakers and power amp that affect the sound and balance. I will reconduct comparisons between the SMPS and LPS when the rest of the system is stable again.

Please share your thoughts, questions and experiences on this route to "perfect sound".

cheers, Coen

Old Install also has blue title bar.
I had to go back to 09z-9b to get the red Title bar, but when entering setup I got the mentioned errors about values 02 and 04 again and after that I could again not go to playlist area.  Aftaer quitting and restarting XXHE 09z-9b the title bar is now also blue here....

I do not like the way of using creditcard again and again to get my software to work....is there another way?


ps. as reply to your earlier question. No i did not do anything with user accounts or something. Just playing music with XXHE or watching movies with Jriver is what this pc is used for...

The old install, if you still have that ?

Otherwise Paypal. If that's for 1.186a I will return the money (2.xx not). OK ?

Title Bar...If you mean the text in upper left corner sying XXHighEnd....etc  this text is blue.

I do not use XTweaks.

After renaming NoXtweaks I can enter settings with no errors :-)
But suspect I am now in demo mode still...how to activate again...

If the answer is "No, I don't use that or I better not in this situation" ... then :

In your XXFolder there's a NoXtweaks.tss file. Rename that to NoXtweaks.tst and I think all will be working normally.

What remains is why this suddenly happens.

Did you perhaps make a new user account or something ?

Hi Juan,

Having a Sabertooth X79 (I got mine in 2012), I can't lower the CPU clock below 1.3ghz, no matter what I try. At some point, the PC refuses to start. I can see the power light fluctuate as if it was attempting to start, but then it shuts...

Jan - No, you will be in Demo. Just watch the Title Bar (undoubtedly Blue).

Do you actually use XTweaks ?
(when the first radio button "No XTweaks" is active, you don't - if you can reach the Settings at this moment)

Normally the CPU is cooled "silently" with heat pipes. However, our PC does it with a very low rev and large double fan cooler (19dBA max = inaudible).

The CU frequency as how I (and others) have it at 430MHz is from the ASRock MoBo which by accident or bug combination (with the OS) allows that under Windows 8 (Windows 10 no change).
