Building a DIY Music Server


Nenon

Recommended Posts

Hi , 

 

I am now putting together a server with the supermicro X10sdv-f motherboard. It has a Xeon with 8 cores .

My mobo is drawing 3 to 4 A @12V .

There is no accessory powered by the mobo except an optane m2card. 

 

I am now powering it with a 12v Sean Jacobs psu .

However since I have been told that I will get better sound quality if I use the atx connector , I want to buy an hdplex dc to atx converter .

Eventhough I do not need high power , Is there any interest to use the 800 over the 400 or 200 ? ( powered by a 19v Sean Jacobs psu )

Thank for your reply . From your perspective sq is the same for 800 or 400 .

 I will be powering the cpu through the atx plug  as there is no 12v  cpu specific plug on my mobo .

Does efficiency of dc-dc conversion is different between 800 and 400 ?

In that case, make sure you have a good beefed up power supply for the 19v rail and much greater than 5A. With 19v @5A rail, I couldn't boot. If you are not upsampling, you "might" be bottle-necked at boot as it requires a ton of power to initialize. Once this is past, the normal operation should be a breeze. I have DIY'ed LPS using SJ regs and have gained and measured a ton of data recently. 200w Hdplex is probably not a good idea for 8-core but depending on which CPU you are using I would at least go 400w. The 800w is preferrable for powering high-power CPU.

 

 

sorry, I can comment the dc-dc conversion efficiency between the two since I haven't used them to power the CPU. For low wattage application, I don't hear any audible differences between the two as I was saying earlier. Maybe you can check with Larry on this. 

The CPU I am using is a Xeon d 1541 . Right now I have no problem booting from the Sean Jacobs 12v @5A using of course the 12v plug on the mobo.This dépends also of the amount of ram you are using I am using 8 giga rdimm apacer industrial.

You can also do some set up in the bios to have a slower boot that will take a little bit longer .

If it is ok with [email protected] , I think it will probably be right at [email protected] with the dc Atx converter 

But I agree that a more powerful psu should be better , however there is no Sean Jacobs psu above 5A . I have found the Sean Jacobs to be extremely good in term of sq and I want to stay with them.

 

For dc-dc efficiency it’s is in the range of 94 to 96 % for both the 400 and 800

Check with him. He has one but does not advertise it. This thread might be of interest to you if you have missed it:

Thank’s , I will definitely ask him as I am currently involved with him buying dc3 and DC4 reg modules 

 

I have one question which puzzled me . On the beginning of this thread you are detailing the construction of a server that you built using three dc3 reg to supply the dc atx for this board . 
I am surprised to see that there is no boost modules for these dc3reg . 
The dc3reg by itself is capable of only 1.5A power which is quite low you need the boost module to go to 5A .

Thank for your feedback . 
 

Also about using separate reg modules to power the atx compared to using a dc to dc hdplex converter . 
I have read that for some mobo the timing to power up the different voltage could be critical and the mobo will not start if that was not correct.

Did you ever experienced difficulty using discrete reg to power the atx connector of the mobo ?

Buffalo bs gs 2016 . There are many report of the sq impact of using pf ultra ocxo clock on this switch .

Did anyone tried the same modification with their less expensive ocxo clock ?

Just so everyone is aware - I am now officially affiliated with Sean Jacobs.

 

Per the forum rules:

1. My signature clearly displays that.

2. I will not promote his products but can answer any questions you have.

 

That is actually good news for the DIY community here, because:

a) I am not doing any of that to pay my bills. Any work I do with Sean is planned to be invested back in my hobby!

b) I will have access to as many of his DC4 rails as I need for my personal experiments. And that is very exciting news.

So what can I do with some extra cash for my DIY experiments and a number of DC4 rails available? Hmmm, I can think of A LOT OF THINGS! And I hope I have the time to do all of them. 

 

You can expect me to continue to share any successful DIY experiments as I always have. I understand if you take my words with a grain of salt from now on. And you should! But my only goal and agenda remains to advance the level of my system.

Congratulations for this partnership.

And thank’s for all the good things you share with the community.

Just out of curiosity, did you use that size for all wires and are those single leads? (meaning; do you have more leads running parallel for the same voltage)?

 

I just used single wire . 
The tdp for this cpu is 45w .... therefore I do not think it will ever draw 12A of current . Typically I measured 1 to 3 A .

You'll need to store the data somewhere, I don't envision going the server client route if I can help it...I hear what you are saying, I listened to a couple of SATA cables and PSUs and was amazed how much that affects SQ

 

Storing all content in RAM is a bit hard, streaming means investing in more hardware as I also listened to the effects of network cables routers etc...choices...

A 2,5” hdd on usb is better than ssd on sata  .

thought the Optane supposedly sounds better due to lower noise than SSD running the OS, I already have 64GB RAM installed and Daphile fits easily in a tiny portion of it as it is.

I am also using an optane 32 go card with the Daphie os on it , a nice sq bump compared to running from a usb stick .

Have you ever tried to put music files on the optane drive and running from there ?

am comparing the two, and with somewhat surprising, well baffling rather,  results. 

All fairly quick comparisons (30 sec or so, with not more than 5-10 sec between them), done using the same track by the late Johnny Cash, 'unearthed' track 14 (alternate take) of 'down there by the train'

Thank’s for these very interesting results .

 

If I understand well you did get the best sound quality with music files streamed from the optane drive , correct ? 
If yes it means it is even better than music buffered and then streamed from ram ! 

Ideally then instead of buffering to ram it will be nice if we could buffer to the optane drive . 
 

Can I ask how did you managed to transfer music files to the optane drive ?

Once the drive is mounted/installed using the Daphile file manager it's a matter of copy pasting folders or files to the free partition of the Optane drive, and sitting back amazed seeing how fast the file moves (actually faster than noticeable). The Optane drive has three partitions, one is free (12 or so Gb out of the 14.x that is available on a 16Gb).

Thank’s for this info . 
I will try it tomorrow and report results .

I did managed to copy some music files on the optane drive as you said it is very easy . 
i will do the listening tomorrow.

If it is clearly a sound quality improvement we may be could ask the developer Kimmo to put that as an option .

Either buffer to ram or music internal drive ! 
Great

I am in bed :-) .... but my system is running because I am burning in some mundorf cabling ( by the way this is also a true sq lift ! ) .

 

If several of us are asking Kimmo , he may do it !

I need to get me some Mundorf wire, I am a big Neotech fan but I hate the insulation used on it....Jupiter wire is also nice.

I was also in neotech copper ( heavy gauge ) , the mundorf is really a big sq lift over the neotech.

I wonder if that SSD noise through the SATA cable is EMI due to the high speed data or is it electrical noise creeping into the MB (or both), do you know Nenon?

 

My best SQ is when I simply unplug the external PSU for the SSD, I could live with an 'OCD switch' for serious listening of a few tracks/albums from Optane...that is how big the difference is for me. No way I am coughing up the dough for 2TB or so local storage in Obscene, eeerr Optane.

 

 

A while ago I did some test using Daphile . I had an internal music ssd on sata and the same music library on an external hdd usb connected .

I was buffering in ram the same piece of music coming from the ssd and from the hdd .

The sound quality was different and always worse from the ssd !
