Holy smoke, are we running Yottabit Ethernet with this kinda speed now?

Seriously, this particular one doesn't seem to be small enough to fit inside a switch

Now I wonder if those Ultra-Fast capacitors were any good if they're powering something else.

Up Squared Board with Celeron N3350 looks quite interesting

$145 for 2GB of RAM and $169 for 4GB of RAM respectively

I could count 2 clocks on one side and 1 clock on the other

 

 

We could actually install two pieces of SOtM tX-USBexp thanks to one M.2 slot and one Mini PCIe slot, of course we'll need an adapter or a riser of some sort

 

http://www.hwtools.net/Adapter/PE4C V3.0.html

http://www.hwtools.net/Adapter/PE4C V4.1.html

 

That's pretty much the only reasonably priced option if we're going after something as small as 85.6 mm × 90 mm for the sake of very short clock cables, it's just somewhat tricky to figure out how to get both SOtM tX-USBexp cards positioned properly because of the constraints on space.

 

The specs claimed 5V @ 4A but we'll have to measure the actual power consumption in order to find out if LPS-1 were any good, of course some of us might consider sPS-500 / Paul Hynes / Vinnie Rossi MINI PURE-DC-4EVR etc. so that might not be such a big deal

Not sure if there were any Classic ThinkPad (with 7-row keyboards) fans here, apparently a group of enthusiasts in China were "upgrading" some old motherboards with Intel i5 or i7 processors as follows

Here are some articles and discussions

https://www.reddit.com/r/thinkpad/comments/5w4zpw/t70_specs_and_3rd_batch_x62_orders_available/

 

Then I checked prices and how many orders were required for each batch of production, they're asking 3999 RMB a piece (about $600) for 100 pieces of "ThinkPad X310" and 2999 RMB each (about $450) for 50 pieces of "ThinkPad X210" respectively.

Basically they're legit and the minimum number of orders seemed to be quite reasonable for such a niche product. Last time @romaz approached DFI in Taiwan and they're quoting $1,500 to get one piece of custom-made motherboard off the ground. Now we're talking about 40% of that ($600) @ 100 pieces or even 30% of that ($450) @ 50 pieces for an older model, not to mention that Celeron N3160 should be even cheaper than those i5 or i7 processors.

 

Do you guys think we'll ever reach that kinda number so that we could make our "dream" music server motherboards a reality? It will be designed exclusively for sCLK-EX so basically there will be no system clocks whatsoever. And then we could use LT3045 for all regulators that require less than 1.0A while the rest could be supplied by an external PSU separately. 4 lanes of PCIe x1 are connected to the CPU of each Celeron SoC and we could have up to 4 PCIe x1 slots available, that would match 4 taps from each sCLK-EX and 4 clocks from 4 pieces of tX-USBexp perfectly. Obviously we won't have on-board SATA and Ethernet etc. to minimize the size of the motherboard in order to shorten the length of clock cables as much as possible.

There's another interesting thread here

Now I wonder if there were anyone who actually modified the system clocks inside SATA BD drives and SLC SSDs by any chance? Do you think that SOtM is willing to work on stuff like this or not?

Someone in Japan actually modified the system clock of this SATA to USB adapter and that particular move turned out to be even more effective than any other tweaks

 

http://blog.jspcaudio.net/?eid=276

 

However, almost all HDD docks and enclosures etc. have DC inputs so basically all power regulators inside them pretty much suck. That's why we might wanna get something like this instead

SOtM SATA Filter II is still good to go, and then we could still supply power directly to that 15-pin SATA power connector without any power regulators whatsoever. Even the system clock could be modified by SOtM easily as it's located next to the USB connector.

It's been one of the most enjoying threads for me here with so many of us who are happy to share their findings, and we also had our 10th anniversary of CA last month. Now I'm so glad that everything is taken care of and many thanks to Chris for keeping everything under control.

So basically this accessory helps to avoid the DC converters and provide clean power directly to the HDD via the 15 pin SATA power. I am just making sure that I understood your point

 

Bingo. 15-pin SATA power connectors have separate pins for 3.3V / 5V / 12V respectively.

 

Almost all 3.5" HDDs and 5.25" optical drives require both 5V and 12V to operate. It's gonna be "nasty" if we're just feeding 12V to the DC inputs of HDD docks and enclosures etc. because something (usually a single regulator) must convert 12V to 5V accordingly.

 

The difference between both voltages is 7V and most likely we just don't wanna waste our time with a significant drop like that.

 

Anyways, most of us should be content with 2.5" drives and that's why we could simply go for ADSAU31R instead

 

http://www.addonics.com/products/adsau31r.php

 

That even allows us to try different SATA cables while we could feed 5V to SOtM SATA Filter II directly, though we still need clean power for that small 4P power connector since the system clock count on that unless it's replaced by sCLK-EX.

 

We could also pay $2.5 to get that PCI bracket and then it could be mounted onto a PCI slot opening.

Hi seeteeyou,

 

I'm powering a 3.5 inch hdd inside a Startech USB 3.1 gen 2 enclosure and my experience is different than you describe here.  The enclosure has a 12 volt input as you explain.  However the 5 volt power source for the drive appears to come from the USB vbus. Enhancing the quality of this vbus power actually enhances drive performance where I can measure variations from 165 to 212 mbs transfers rates. SQ improves as well.

 

Hi lmitche,

 

Many thanks for sharing you tips regarding vbus power since I didn't expect that would affect both USB DACs and HDDs, the most interesting part would be both quantitative and qualitative changes were observed. We learn something new every day.

 

Regarding the current of HDD docks and enclosures, now I realize the former ones are definitely good for both 2.5" and 3.5" drives but the latter ones might be a different story?

 

We need Type-C connectors on a server to reach 1.5A / 3A / 5A maximum current. Let's say we're talking about the legendary tX-USBexp here, we should be limited to 0.9A since Type-B connectors aren't really meant for anything that requires 1A or above. We could still get away with 3.5" HDDs because even 12TB ones would require only 0.4A from 5 volt power source

 

https://images.anandtech.com/doci/11842/wd_gold_12tb_bg.jpg

 

However, some "monster" drives such as this 2.5" SSD from Crucial would actually require 2A

 

https://www.vortez.net/articles_file/29793_crucial-bx100-1tb-bottom.jpg

 

1A for Samsung 850 EVO

 

https://images-na.ssl-images-amazon.com/images/I/91gOObm6rFL.jpg

 

0.5A for another one from China

 

https://ae01.alicdn.com/kf/HTB1CUvZKpXXXXa.XVXXq6xXFXXXG/F9-1TB-KingFast-2-5-SATA-SSD-For-Dell-HP-Thinkpad-Lenovo-ASUS-Acer-Sony-Toshiba.jpg

 

Fortunately we don't really need any 1TB SSDs since HDDs are so much cheaper while we're also getting a much higher capacity. However, the USB vbus of HDD docks alone (i.e. inevitably some power should be drawn from 12V DC input after going through a regulator) might not be good enough for some hungry 2.5" SSDs if a server weren't having USB Type-C.

 

I really was paying too much attention to 5.25" optical drives in the first place since I just kept thinking about how Addonics would manage to provide compatibility for both HDDs and optical drives in the first place. I checked a bunch of BD and DVD drives, so far 5 volt power source requirements seemed to be ranging anywhere from 0.8A to 2.0A

 

http://www.ixbt.com/optical/dvd-01-03/pioneer117-label.jpg

https://ssli.ebayimg.com/images/g/sNkAAOSwhQhY0y0a/s-l1600.jpg

 

Some USB DACs don't really need vbus at all when they're getting power from an internal PSU instead. However, sometimes they might wanna keep the connection alive by means of computer "handshake" and that won't happen if vbus weren't present. Maybe the performance of vbus still matters even if only computer "handshake" were involved? Now I wonder if similar cases were applicable for both USB DACs and HDDs.

[seeteeyou]

The whole is greater than the sum of its parts.

 

While improving an individual system clock might not be necessarily such a big deal (who knows?) when we're merely focusing on a single piece of component, IMHO it's still a good idea to consider how a mediocre system clock might end up being the weakest link that could potentially "ruin the day" for a server. As long as we've got something that's sticking out like a sore thumb, it's still somewhat tricky to estimate how much damage is done to the overall performance.

 

Maybe that's why in theory the performance of a built-in system clock wouldn't even make any differences for stuff like Ethernet devices, in practice we still have to figure out the opportunity cost of NOT replacing that with sCLK-EX. Some of us were dedicated enough to modify every single system clock with throughout the entire chain, it's considered a 100% sCLK-EX rig since they're leaving no stone unturned. As a result, we've gotta give credits to BOTH presence of superior system clocks AND absence of inferior ones.

 

Like what Roy mentioned before, this game should be all about minimizing the overall amount of noise (in terms of system clocks and power etc.) since it's gonna up the damage after going through so many components. Even the manufacturers of computer parts themselves might not be aware of how they're contributing to a complete system because plenty of them wouldn't really consider PCs to be toys for we audiophiles in the first place.

I am presently inclined to move completely to compact flash storage using a series of 512GB compact flash cards. It turns out the type 1 compact flash cards draw considerably less power than all SDXC cards (up to 10x less!) and thus far, I am finding a 32GB CF card to sound better (by a small but very noticeable margin) than any SD or microSD card that I have.

I have noticed some SDXC cards can draw as much as 0.6A and so a 64GB SDXC card potentially could draw nearly 10x more current than even a 512GB type 1 CF card! SD cards consume fewer watts than SSDs but because most SD cards are 3.3V devices (as opposed to 5V devices), the more power hungry SD cards (the very fastest ones) actually draw the same amount of current as an SSD. 

 

I just checked how far one could go in terms of stripping Windows way down, it's OK to get away with 4GB and 8GB for Windows 7 and Windows 10 respectively

 

 

Let's say we're comparing those ULTRA expensive SLC industrial flash memory cards, both CF and SDHC turned out to share very similar current values

For those of us who are willing to burn (somewhat) serious cash, we could take a look at the numbers of 8GB ones (i.e. good for stripped down Windows 10) that are 50 mA and 60 mA for read and write respectively

Since we're able to write-protect SD cards with ease, we could fit some of our favorite albums on 1GB / 2GB ones that would consuming ONLY 28 mA a piece

Of course we still need to pay attention to the difference between typical values and the maximum as shown in those datasheets linked above. Not to mention that we're talking about $35 for 1GB / $60 for 2GB / $127.5 for 8GB since all of them are industrial flash memory cards with SLC chips.

Intel Atom C3000 Series

Could hardwiring be fairly straightforward? Leaving one end of DC power cable(s) unterminated and then remove the DC power input on the motherboard like this

 

http://www.laptoprepair101.com/dc-power-jack-repair-guide/

 

Trace the pins on the motherboard and make sure that we're gonna do the right thing, then solder each and every wire of that DC cable directly to those corresponding pins on the motherboard afterwards. Of course we better practice with a direct cheap motherboard before we dive right in.

 

For those of us who would like to power RAM directly instead of going through those regulators, maybe we could pay SOtM to mod the right motherboard for us

 

http://www.tirnahifi.org/forum/viewtopic.php?f=15&t=3267

http://www.aktives-hoeren.de/viewtopic.php?f=30&t=6015

 

Of course we could also design our own motherboard or maybe a carrier board if there were a relatively large group of us who are interested, then we could simply pick XLR jacks for DC power inputs.

 

BTW, what if we simply swap that those 5.5-mm DC power input jacks with better ones with lower impedance?

Two more significant boosts to SQ

So I went with scenario 1 and worked on optimizing it. The first significant boost in SQ I got is when I removed the enclosure of the 2.5inch 2TB HDD which was powered by USB3.0 from the tX-USP-exp (LPS-1). I went with the recommendation of @seeteeyou and ordered the SATA to USB3.0 adapter from Addonics. This enabled me to power the HDD from a TP-Link power bank and obviously I switched off the Vbus power on the tX-USBexp. This was a great improvement, more than switching between any of the above 4 scenarios. Thank you @seeteeyou, I am grateful! this is the link if someone is interested.

For those of us who might be interested in a very different kinda trifecta, SOtM could modify three clocks in a row like this

1. One clock inside the 2.5" SATA drive
2. One clock inside the USB-to-SATA adapter
3. One clock inside tX-USBexp

Most likely we're gonna need something like Intel X25-E according to @romaz because of its low current draw, the clock is sitting between the SATA connectors and the SSD controller as shown below

There's another $80 evaluation board MIOE-DB2100 that's designed for a different model MIO-3260 with Celeron N2930

We could power MIO-2360 and the expansion board separately so that could be a bonus, not to mention that both of them don't come with 5.5-mm DC power connectors (i.e. high impedance) by default.

 

Now the question really is how much is a custom-made expansion board that's compliant with their specifications

Its a celeron j900 10W motherboard, theres a  DC input to the motherboard, one to the hard drive and one to the 'Pico' type dc - dc connector which seems to power the optical drive. Those are Mundorf Capacitors on the regulator board- very expensive, it apparently ran @ romaz set up pretty close, so it would be very interesting to hear @ austinpop's evaluation.

 

That's quite an impressive achievement without any sCLK-EX / Paul Hynes SR7 goodness whatsoever, maybe we could actually learn a thing or two from their magic sauce PSU?

So much would be lost in translation when machine translation could be a disaster of some sort.

Anyways, maybe at least part of the "magic" might be coming from those insane capacitors even though the output impedance might not be all that impressive when compared to the numbers we're getting from Paul Hynes.

 

Both Simon Tuned and Kenneth Lau didn't seem to provide any kinda numbers whatsoever, and then most likely we wouldn't expect anything from CHC as well.

 

Since Vinnie Rossi stopped making MINI PURE-DC-4EVR already, our PSUs of choice would be left with LPS-1 / Paul Hynes / SOtM etc. in addition to these FINEMET core transformers from Japan

I checked everything on Micron and Samsung etc. but pretty much all of them would exceed 1,000 mA. Of course our winner is compatible with Bay Trail (e.g. Celeron J1900 inside ZENith SE) as well as Braswell (e.g. Celeron N3060 / N3160 etc.) that could be found in many motherboards

But Zenith SE raised a curiosity what is the specification of it's linear power supply.

 

Does it surpasses the Paul Hynes SR7 performance!!!!!!!

 

ZENith SE should be limited to 100 units and they're down to last 10 or so already.

 

It's gonna be a stretch but one of us with ZENith SE plus either SR4 or SR7 might give this a try. Turn off ZENith SE and remove the cover. Disconnect the SATA power cable from the Samsung SSD inside ZENith SE and connect that to another SSD inside one of those spaghetti solutions. Turn ZENith back on and pray that nothing bad would happen. Now get back to the spaghetti solution and play a few familiar tracks. Then power everything off and then play the same tracks again with either SR4 or SR7 afterwards.

 

Granted we're still comparing a different DC power cable from SR4 / SR7 to SSD versus another cable from that CHC Triple-Linear LSU, though it's better than nothing.

 

Or someone in UK could also try that DC3 linear PSU from CHC for 30 days and see if that were really MUCH better than LPS-1 etc.

Awesome! That would a great service to give us a much better idea about where CHC would stand. Hopefully you're gonna swing for those Mundorf caps as well.

By powering the CPU with a dedicated linear power supply and given the USB controller is within the CPU provides excellent results without requiring dedicated USB boards. There are, of course, lots of other tweaks at the firmware level on the board, on Linux Kernel and on the software player as well as a very specific Linear PSU architecture to get these results. This has puzzled many reviewers, who were sceptical at first - how come this system without OCXO clocks, SATA filters, RAM Filters, etc, etc, etc can actually sound this good? It's all about the synergy between the board, the linear power supplies, the firmware and the software. Using this hardware combination is a conscious design option, not a matter of reducing costs. We have tested dozens of boards on the oscilloscope (higher and lower-powered) and we could have easily used similar ones at a third of the price.

 

The ethernet ports on the Zenith are no ordinary Ethernet ports you find on normal "consumer-grade" boards. The ethernet ports have 4 separate isolation transformers each to further isolate the connection (4 small grey boxes right before each ethernet port). We also do extensive anti-vibration treatment of the chassis, the LPSU and even the SSD, converting vibration into very small amounts of heat. This makes a very audible difference in sound quality.

 

https://devialetchat.com/showthread.php?tid=3853&pid=68044#pid68044

First, the architecture of the USB Controller makes a difference. Typical boards have a USB controller at the CPU level and another at the motherboard level. When we compared boards to use with the Zenith, boards with two-level controllers always shown higher levels of EMI on the USB line. The motherboard on the Zenith only has a single USB controller directly on the CPU and the CPU alone has it's own separate linear power supply. If you have ever heard the difference in sound quality between a Zen (which uses a single LPSU) against the Zenith (with 3 LPSU) you'd know right away there is a significant difference. This is what differentiates the Zen and the Zenith the most, more so than using SSDs.

 

Second, we've worked on reducing vibration on the electronics of the Zenith. Whilst the clocks on a Zenith are not OCXO 10ppb, this vibration control and the LPSU do make all clocks on the motherboard perform their best and there's no cabling to contend with as when using external boards. 

 

Third, don't dismiss the difference the software and firmware can make to the sound of the system. The memory playback alone on the Zenith makes a very audible difference.

According to Innuos Director Nuno Vitorino: “The SSD and CPU are the noisiest components so the system benefits a lot with them being separately powered as it helps them not to contaminate other components.”

 

He continues: “The larger transformer isn’t about reducing noise but essentially to reduce impedance on the PSU as it can fill up the capacitors quicker. This allows the PSU to provide faster transients to respond to power requirements from the different components. It’s also a much better shielded transformer and reduces high-frequency vibration.”

 

“The funny thing is that these kind of factors look like they’d make a lot more sense in an amplifier but we have no doubt in my mind that they’re a factor in a digital source too – just compare a Zenith to an SE and you’ll hear it right away.”

 

“Dr. Sean Jacobs is the genius here. He designed the PSU circuit exclusively for us and it is where math comes in. Too much [transformer] will not make much of an effect and you’ll be adding up just dead weight and adding cost. You need to evaluate the PSU circuit, measure the capacitance and then calculate how many VAs you need for the toroidal.”

 

Quote

We configure the SSD controller extensively to limit the amount of noise the SSD can do on the system, helped by the fact the SSD uses its own linear power supply as well as vibration treatment.”

 

In other words, it's really all about the meticulous details as well as the road less traveled if you will. Otherwise @romaz wouldn't be so impressed by its performance even though he's got his own custom server (slightly better than ZENith SE that is) already.

I am now using one 2gb memory module on the X10SBA. I am using crucial memory modules. 

I will look in the memory you recommend as lowest current draw. From my reading I got the info that Samsung memory modules were very energy efficient.

 

The ones from Micron should be a joke because the current draw seemed to be nothing to write home about. Samsung ain't too bad the and lowest numbers of M471B5674QH0 are kept under 500mA. SK Hynix should be fantastic and HMT425S6CFR6A would give us numbers that are belowe 400mA. I just kept looking but Crucial might not be willing to publish any numbers or something.

 

It ain't an exhaustive list by any means, just giving everyone a glance at what kinda DDR3L memory modules we could get on the market right now

And then we've got some "monsters" from a few companies, unfortunately they're just boasting "low power consumption" without bothering to back that claim up with a datasheet of some sort

There is also an important parameter to consider I think is the latency ?

 

It's more likely to be a big deal for gamers according to this post

Actually Roy was throttling the speed of both CPU and RAM to 800 MHz so they're synchronized to the same frequency. And then we could also tweak the PLL with ClockGen

Maybe we could dial something down a notch for the sake of lower power consumption?

 

BTW, someone is gonna share something to slim Windows 10 down with NTLite soon

And then there's also another one here

Windows 10 LTSB 1607 (32bit) NTliteTiny2 - 1.2 GB (no swap)

 

In that case, Windows 10 could be installed on SD cards with the lowest power consumption (28mA read / 55mA write) ever
