NAS Killer 5.0 (Complete)

I am gearing up to build an NAS Killer using the board expected to be used when it becomes official. The below is what I am currently gathering for parts. The PSU is one I picked up last year on the cheap.

Not listed below are the 6x WD Red 6TB NAS Hard Drive - WD60EFRX that I am pulling out of my Synology NAS and moving to the server.

Current All in cost (not including 6TB drives is $988.07 before tax

I will update this post as things develop.

Let the pictures begin!!!

All parts are installed now. I have a few more hdd’s to slot in and some wire clean up to do.
Rosewill Case is on rails and in my rack.
The Rack was killer OfferUp find. I grabbed it for $40

More to come…


Noob here.
I just ordered a X10SL7F, along with one of the F80s.
Does it matter which slot I run the F80 in…or will it run at full speed in either slot?


You would need to run it in the X16 slot since the F80 is 2.0 x8, but I bet you would still have good results with it on an x4 2.0 I’d try it on both and see if it makes a huge difference.

That’s what I figured.
The F80 was an impulse buy. Didn’t even think of the slots.
Parts are still in transit, so I’ll find out when they get here.

Hi. I’m trying to piece together a similar system. Are you sure this ram works with this board? The specs here: X10SL7-F | Motherboards | Products | Super Micro Computer, Inc. say 1600MHz ECC DDR3 SDRAM 72-bit, 240-pin gold-plated DIMMs. Or does this mean “up to 1600MHz”?


This is what I have running in it. I reviewed it all with JDM ahed of time.

Awesome! I’m pulling the trigger! Thanks for the response. Are you happy with this build after putting it together? Anything you wish you would have done different?

No nothing I would change at this point. This build does exactly what I need it to do with plenty of power left over for other stuff.

@doctapeppa Any update on your progress?

I built it a few weeks ago. It’s running great! The bios is a breeze to go through and having all of these ports available for so many drives is great. It’s currently filled with 42TB from 8 shucked drives and it’s sitting in an Enthoo Pro case (which I’m super happy with as well!) My cable management is horrid so I don’t think it’s picture worthy but this thing is more beast than supermodel anyways.



I’ve started on this build, but I think my memory choice is suspect. When I power on my system, I’m getting to the Supermicro “system initializing” screen with an error code of 15. Can anyone confirm if I went the wrong direction with my RAM choice?

You’re fine. “15” isn’t an error code:
50 - 55 are Memory Error Codes:

Thank you for the codes! So, how long does it usually take to post? I’m pretty sure I left it going for 5 minutes. I’ll try again tonight and report back.

Unfortunately, I’m stuck at code 15 even after 30 minutes. If not memory, bad motherboard or CPU?

From Coz’s post code list above, code 15 is saying that North Bridge failed to initialize. I recommend powering down and double check your RAM compatibility, by emailing Supermicro directly.

Thanks for the advice, I reached out to SMC and they suggested a few different troubleshooting steps. It turns out I had a very tiny spec of what I think was thermal paste blocking just one of the CPU pins/pads. I cleaned and reinstalled the CPU and I’m now posting fine and the system have successfuly loaded ESXi.


Great to hear!
