truenas with new intel p5800x optane

That's posted in April and therefore someone did manage to purchase P5800X somewhere, and then these guys in Hamburg should be "claiming" to have a whopping 21 units of 800GB P5800X in stock

How and where on Earth did they find so many drives if that "magical" number were true? Even Intel couldn't provide any straight answers back in January

 

P5800X how to actually buy it?

In addition to SSDs, there's also Optane DC Persistent Memory with MUCH better performance but they do require 2nd / 3rd Gen Xeon Scalable processors with specific motherboards

One thing I'd like to know, on motherboards that have separate EPS +12 volt and ATX +12 volt connections do you have to disconnect the +12 v connection at the output of the ATX power supply if you want to power the CPU separate from the motherboard? Sorry if that's a newb question. I guess I'm a newb.

Depends on the motherboard design. In most of the Supermicro server motherboards and also Asus C621, you would have to - they are just wired in parallel. Most, if not all, gaming motherboards, they are independent rails for a reason and it would not boot if you don't connect the EPS since there is no power to CPU.

Thanks.  I have an Asus ROG motherboard so I guess that means I don't have to cut it.  Great. If not it would mean a lot of fiddling with connecting and disconnecting that ATX 12 volt power while experimenting with different schemes.

this one is 805. The 211 is the one I have been lurking around and would probably be my next SET :-)

aha, the top cap fell of the picture ;-)

 

Nice Graphite anodes! I'm into mesh tubes lately, with a monster build around a PL519 in G2 Triode ongoing for quite a while now.. 400H chokes etc...should be finished when the other monster project is done, my Trionor front loaded open baffle speakers,

Got my Taiko DC-ATX today here in Brexit UK after spending 2 days in Customs and arrived with a large rip to the box, what did they expect to find inside?

Big improvement in every sense over my HDPlex 800W, mostly clarity and lack of grain and distortion, warmer and more natural througout the frequency range. No brightness basically more transparent to the source after only a few hours warmup. Cymbals are cleaner, voices more natural, you can distinguish the differing deep bass notes.

Using it to power the dual sage C621 board, with an unregulated power supply, Mundorf Caps including silver in oil bypass caps. 2 chokes and 600 Watt torroidy audio grade @ 36V ( the metal cased supreme didnt fit my case).

I might change the transformer and rectifier bridge when @Nenon releases the specs but won't touch the caps, they sound good after 200 hours but mine took 9 months to lose a slight mechanical edge and let the music  flow.

Only niggle is lack of PCIE output so I just powered the 2 CPU inputs on the board, its a great upgrade.


Very Nice but we do want pictures. 😇

Hi asking for some very basic help.

 

I have got my Taiko ATX however not sure how to connect the SATA power lead. My SATA lead has a 6 pin connector (as used on the HDPLX 800) but the Taiko SATA out has four pins??

Thanks Nenon

 

I need a cable like this?

 

sata.jpg.a75ad65e809b27694e67d0c385d7f267.jpg

 

I am not a fan of SATA drives, and haven't looked at them in a while, but generally speaking the SATA connector provides 3 voltages (3.3V, 5V, and 12V) and different drives use different voltages. Some spinning hard drives use the 12V for the spinning and 5V for electronics. Some solid state drives need only 5V, others need 3.3V, etc. You would need to check the specs of your drive and what voltages are needed.

And then you need to find a cable with the correct pinout or get one made for you. Here is the pinout on the Taiko ATX:

 

766024887_ScreenShot2021-05-07at9_02_48AM.thumb.png.72d4fcaeb98e5aa6d54ea3b6d34f1b63.png

 

You can use any of these connectors:

Part number: 39012040 (white)
Part number: 39012045 (white)
Part number: 39013042 (white)
Part number: 39013045 (black)

 

With these pins:

18 AWG Gold plated: 457501212
16 AWG Gold plated: 457503212

 

On the other side, it would be a standard SATA connector.

You can ask the seller of the cable you showed on the picture for the connector type used and the pinout, and it if matches the above (and your SATA drive does not need 3.3V, which is very rare anyway), it should work.

Or you can ask Ghent to make you one.

 

Perhaps other people who use SATA drives would have some better ideas, but that's all I can offer.

Thank you for all that information Nenon

 

I only use the SATA ssd to boot the OS into RAM and then switch the ssd out. It only requires 5v.

 

The HDplex 800w's SATA output has 6 pins but the two central ones seem to be superfluous.

The unregulated LPS I am currently using has about 1.4mOhm output impedance (it also has about 5uV ripple).

 

@Nenon 

 

Wow, 5uV = ~-135db of rejection ( assuming a ~30v rail ) ! 

 

I have been playing along in the background for a while using simulations of an unregulated supply based on the component choices in your earlier posts. With components listed and tweaking components parameters to near ideal performance levels its hard to get <3mv pk - pk @ 1 amp constant load.    

 

5uV is exceptional. Can I ask how you measuring the ripple and and under what test conditions ?

 

Thanks.

Struggling to get the Taiko ATX up and running. I cannot get the system to boot up beyond bios screen, the  sata OS ssd and my nvme m.2 storage drives do not show up in bios screen. 

If I substitute my hdplex 800 it boots up with no problem??

Have you tried simulating the dual choke CLCLC configuration?

Try booting from a USB stick (disconnect the SATA and NVME for the test). This should narrow down the problem between:

a. not having enough power to boot; or

b. something related to powering the SATA / NVME

If you can boot from a USB drive, it is likely "b". Sorry, I won't be around later to help troubleshooting, but other people here can advice.
