Who is that guy at 0:21 and why does he turn that oscilloscope upside down. Maybe they must be rotated every now and then like good wine, to get rid of sediment :p
it's not an osciloscope... it's an ǝdoɔsoʃıɔso It is a similar device, performing a similar function, but it works on the southern hemisphere of earth only, and it only works for measuring PCB's that are mounted upside down.
I used a Supermicro motherboard when I built my first PC in the late 90's. They were the ducks guts then, don't know if they are now but glad they still exist!
EEVblog that unpopulated area near the SATA ports was described on the silkscreen with SAS.. Which is a storage interface like SATA, more precisely SATA's bigger brother for really heavy lifting.
Those unpopulated parts of your motherboard would be a SAS controller and its connectors, dead giveaway by the silkscreen markings. Oh and hello to your new assistant at the beginning of the video :)
For anybody still wondering what the unpopulated headers on the lower right corner of that server motherboard are, they're SAS connectors (or at least they would be). Those connectors would connect between a RAID controller (which would be the BGA pad), and a hot-swap SAS hard drive bay (which would house 4 or more hard drives), so that you don't need to run individual cables. Serial Attached SCSI is compatible with SATA II.
Hi Dave! Those are SAS HardDrive connectors, and the big chip next to it is the SAS controller. They are used in Server applications due to the extreme reliability and very high R&W speed.
These wiggly traces @ 10:15 are for impedance control purpose. It's to minimize impedance variations. If they were parallel to fibers, some lines could end up going directly over a fiber and some over a slightly thicker layer of epoxy.
What a surprise, hearing Latvia on EEVBlog. Dave, have you ever considered putting your mail on the map, so to say? Could be fun to find out that you've received mail from most of the worlds countries. But then again, word of warning, it might trigger some sort of competition between EEVBloggers and get you completely flooded in mail...
5:15 If it wasn't already told, the unpopulated part of the Xeon Motherboard seems to be for some SCSI SAS ports. SCSI HDDs are pretty common on servers, so it's an option that some may require.
You are actually right on the boot from sdcard theory. But the standard is to boot from a USB stick secured inside the cabinet by plugging it into that vertical USB socket. Fits nicely within the same height as the CPU heat sinks. Biggest use is to boot a VMware ESXi OS, which uses networked storage.
I am not sure if you would call it irony or what but talking about a security fuzzing tool in the same episode as installing random software through the mail sure is something.
We have many of those supermicro boards at work. One died when the Altera CPLD next to the PCIe connector got fried in an ESD event. Somebody "accidentally" grounded themselves on it while putting a card in. Next time we powered up the system, that IC heated up to over 100C within seconds, which I discovered quite painfully during debug.
The onboard USB A connector is great for plugging in a bootable thumb drive. Image a bunch of them on your desktop, have data center operptions guys pop them in boards. Bingo! As mentioned by others the unpopulated "bits" in the corner are SAS connectors and the bga next to them would be a storage controller IC. Probably LSI Megaraid or Adaptec of some kind. Due to the lack of a dimm slot near by it would be for a HBA (host bus adapter, just a disk controller) and not a proper RAID controller. The SuperMicro X9 series has a lot of different models in it. I've seen enough SuperMicro boards to know that they often design one or a few boards and then selectively populate them for different models. Someone above mentioned the lack of proprietary connectors. This is because SuperMicro is a OEM or WhiteBox manufacturer. They don't integrate as much as Dell/HP/IBM. Many of their boards even fit in eATX or full size ATX cases where the other already mentioned brands are less likely to make such boards.
Unpopulated places on motherboard are for SAS controller for sure. There are even labeled as "SAS0~3" and "SAS4~7" (usually there are 4 SAS ports on single connector, you have to use split out cable).
The unpopulated area on the mainboard is for an onboard SAS controller. There are markings reading SAS 0~3 and SAS 4~7... those are unpopulated SFF-8087 connectors for SAS and as the large BGA package area is directly beneath it is a fairly good assumption.
The unpopulated stuff looks like a SAS port or two and the controller for those will be the unpopulated Bay pad. Sitting right down near the southbridge, or may even use a few points lanes if installed. SAS is a high speed enterprise-level storage backplane.
EEVblog The unpopulated "connector pins" I think are for m-SATA, very small SSD cards which you can snap in there directly on the mainboard. The other ones with the BGA pins are for an SAS (SerialAttachedStorage), an faster connector than SATA for the drives. The serial port by the way still mostly is used for UPS devices :)
Dave The unpopulated BGA on the edge of the motherboard board looks like an optional SAS controller ( type of HDD interface ) and its supporting components. With the size of the space for the header it will support an additional 4 drives.
This was JUST like those shows where they challenge your concentration and no one sees the pink rabbit. After paying close attention to Dave I remember thinking "did I saw someone else moving in the background a minute ago?" I had to rewind and watch again: I had actually missed the whole equipment turning show. Unbelievable.
The un-populated area marked with l-sas and the bga package next to it is very obviously a raid controller and SAS connectors to go along, they very likely have another SKU of the board with a built-in raid controller.
The un-populated part of the motherboard is for the SAS controller and SAS connectors, it's somewhat comparable to SATA. They are very common in servers.
The underpopulated area is for a SAS controller and SAS drive connectors, which would point to this being a workstation board rather than a server grade board.
EEVblog Who else spotted the spelling mistake at 14:28? "This can be mdofied during configuration" ;) Great video as per usual Dave. Interested in the sat phone! 73 M6EXH
I like how some random guy just comes and flips that component over in the background. As if anyone was paying enough attention to realize that it was upside down...
Dave, when I saw your "Mini Me" on screen I lost concentration on your rant and started waiting to see if he appeared on screen again! So, I must watch this again...
The missing components are for for a SAS expander that is not included as this is a workstation board. Also the RAM you have may not work as this board needs DDR3 memory.
"...and he was henceforth known as 'Flipper'." "In Australia electronics rotate the other way around." "Nooo, now all the electrons are gonna fall out. Classic trap for young players." "Like fine wine oscilloscopes need to be rotated every once in a while." "I believe the instruction said 'Turn the device ON'." ...ok, i'm done now...
Dave, I may be wrong but I think those "fancy-pancy" traces on the motherboard may have been intentionally routed in unusual angles to avoid running parallel or perpendicular to the glass fiber of the FR4 material. Some studies say it has an effect on Signal Integrity if I'm not mistaken.
Full atx case and watch your air flow they can get quite warm when loaded with ram in normal desktop cases. I run them fully loaded with 16gb sticks:) 256gb total Minimum you need with thouse cpus is one ram stick per cpu. The missing stuff is a megaraid/LSi sas controler:) Also that board also has a built in IP kvm (ipmi) what ever you do dont put that on the internet, it has a default internal login you cant disable. (ITs enabled by defualt and will grab an address via dhcp) But it is awsome for remote use if you can hide it behind a VPN. And can do everything from rebooting to installing it.
AH right.... extended ATX is what you want. Quite a few gamer cases them first google result i got: www.newegg.com/Product/Product.aspx?Item=N82E16811139029 That looks like a that woudl be a ideal case due to large airflow vent.
I stand corrected. I did some digging. The 2 ports are for SAS connectors. Basically SATA but with power and data integrated together. Each one can link off too 4 drives.
januar324 That's not quite accurate. SAS is Serial Attached SCSI. You can attach SATA drives to a SAS Controller. There's a huge difference between the two instruction sets though. Each link can actually link out to a more or less infinite amount of drives, by the use, you can get up to cartoonishly large amounts of connections. over 65,000 devices can be controlled by the use of backplane expanders.
Monkeh616 thanks both of you for the clarification. I looked at the diagrams and tried to find a bit on what they where so when I looked for sas that's what I got. Good to know :)
@ 6:53 that's probably a XTP connector (DNI'ed) between the two processor sockets. That looks like a high end workstation with 3 PCIe x16 slots for very expensive video cards and SAS RAID cards. @ 10:20 the zigzag of traces has to do with avoiding difficulties encountered with high speed differential signals and the fiber weave of the PCB. Check out this info taken from an Intel's white paper on fiber weave. (which I participated in) download.intel.com/support/processors/quark/sb/quark_pdg_330258_002.pdf See 2.6 Minimizing the Effect of Fiber Weave especially Figure 13. An Example of Zig-Zag Routing (on page 27) Best regards, a former Intel insider
The unpopulated area on that motherboard would have been for onboard SAS controller, Serial Attached SCSI, I used to assemble HP servers so have used them a few times :)
You will need a case that supports HPTX motherboards. Your main options would be from Lian Li, Caselabs, and Little Devil, but be expected to pay for it though..
The unpopulated BGA in the corner is probably a SAS Controller(likely LSI), the connectors that are unpopulated there are marked L-SAS(O), SAS controllers are usally BGA packaged.
It's interesting to see they whacked good ol' Altera Max II CPLD there (on that dual Xeon thing), it's not a daily routine to see that stuff on a PC motherboard.
EEVblog Yay for Supermicro (Running my fileserver on one of those, though an X7DBE one). The unpopulated stuff in the corner is for an SAS (Serial Attached SCSI) controller and ports
the unpopulated stuff is the sas array for scsi and the case needed is a eatx (extended atx ) the ram will be if not matched pairs you can use 1 dimm in each bank if dual channel or more channel my need 2,3,4. sticks in each
The missing section from your board is for SAS ports and the controller chipset for them, and a few spare connections. No worries though, SAS drives wouldn't do you a whole lot of good anyhow.
Oh that kangaroo is "Anton", a Benett-Wallaby originally from Tasmania. He escaped on Oktober 6th 2014 and was cached end of January this year. That's quiet a big deal here in Austria in the media with escaped kangaroos. They seem to be very skilled escapeartists and feel at home in our woods.
Hi Dave for this motherboard you are going to need a video card as well and the ram DIMMs should be matched make sure you use the same ram dimms with same frequency and latency otherwise you can experience all kind of weird stuff from very bad performance, blue screens or system not booting at all....you get best performance when you use matched pairs of ram sticks and put them in dual or quad channel :) thanks for the video :)))
Dave, you need to invest in a security system. There's clearly an intruder at 0:20 of the video. Once he realized he was being filmed, he pretended to use one of the scopes. Stay safe Dave.
I built a system using the X9DAI for a friend using 10 core xeons. This is a nice board, but it has a non standard mounting hole layout with only 5 of the holes lining up correctly. One option is to use a Supermicro case, or if handy with a drill add the 4 remaining 4 mounting holes to a different case.. You can run these boards in single, dual channel mode using 1 or 2 dimms to get it going, but it is best to populate all the build slots first for best performance.
Guessing from the nearby areas labeled SAS, those big unpopulated areas are probably for an optional "serial attached SCSI" (fancy sata) raid chip set.
Dave did say he was looking for a helper remember? He put an ad out? I think he found someone and in Dave's usual quirky way, this is how he is introduced. Very geeky. I like it.
Yepp, LSI SAS controller with 8 sas port. Could be awesome drive with ssd sas in raid 10 :)))), but unfortunetly is unpopulated. Anyway, again great vid, and please please tear down the satellite phone :) I always wondered how we (visitors, forum members) like You. Maybe You have to make a marathon mailbag opening day, to clean the mailbag shelf :) It will be really funny! Thanks Dave! (a german visitor...)
The Xeon has a quad channel memory controller in it so what you need to do is match voltage, rated speed, and capacity of at least 8 DIMMs if you're going to be using both sockets. CAS latency isn't as important here because all DIMMs will be set to the slowest latency. If you're pulling DIMMs from old servers make sure these three requirements match or some of your DIMMs are going to have a very short life. If you can't match this many DIMMs at first you can run 4 DIMMs in dual channel mode, or run a single socket in quad channel mode. Also, make sure you populate sockets of the same color. Some chipsets are picky about which sockets you populate first, so if you don't get a POST just change to the other color set.
Dave, your intern seems to be doing a great job there in the background :-)
Lol either that or Sagen has grown up really quickly
quincy8557 Sagem?
Who is that guy at 0:21 and why does he turn that oscilloscope upside down. Maybe they must be rotated every now and then like good wine, to get rid of sediment :p
you must rotate oscilloscopes every so often to keep their internal oscillators running accurately.
Dave's subtle way of saying 'the position has been filled' no doubt. :-)
Right, let all the other video bloggers follow and get their sidekicks to rotate their scopes.......😃
don't turn the scope upside down, all the signals will fall out!
it's not an osciloscope... it's an ǝdoɔsoʃıɔso
It is a similar device, performing a similar function, but it works on the southern hemisphere of earth only, and it only works for measuring PCB's that are mounted upside down.
Great mail bag Dave very entertaining, just thinking about what I could send you!. Don't go mainstream we need you here channeling your thoughts.
good to see your assistant is making sure your left-handed oscilloscopes are kept the right way up :)

I would highly recommend using 8 of the same DDR3 modules on that motherboard, that way you get quad-channel memory on both processors.
Unpopulated places on motherboard are for SAS controller for sure. There are even labeled as "SAS0~3" and "SAS4~7" (usually there are 4 SAS ports on single connector, you have to use split out cable).
Love the recursive "Oh, there's chocolate" at the end. :)
A ghost just turned an oscilloscope upside down.
I saw that guy the other day on the office cam. He kept wandering up and down the bench looking at things before Dave turned up.
The unpopulated area on the mainboard is for an onboard SAS controller. There are markings reading SAS 0~3 and SAS 4~7... those are unpopulated SFF-8087 connectors for SAS and as the large BGA package area is directly beneath it is a fairly good assumption.
Digging deep in the old Davy Jones crest and what do you get? Chocolate!!! Awesome Video.

CalcProgrammer1 yeah it looks like one of the EATX or possibly XL-ATX boards.
Supermicros site says E-ATX
The 2 missing ports on the bottom could be for msata ssd drives

I think its XL-ATX, and to get the best prefromance you will need to populate all the 8 black DIMMs for quad channel memory
It's 8:50 am here. I want to watch Mailbag! But then, I won't have the fun of watching it later.... Life is so cruel.
Connector between the CPU sockets is an unpopulated TPM(Trusted Platform Module) socket for drive encryption.
Haha that tunnel photo is hilarious!

SuperMicro make great Server/Workstation boards
I built a system using the X9DAI for a friend using 10 core xeons. This is a nice board, but it has a non standard mounting hole layout with only 5 of the holes lining up correctly. One option is to use a Supermicro case, or if handy with a drill add the 4 remaining 4 mounting holes to a different case..
You can run these boards in single, dual channel mode using 1 or 2 dimms to get it going, but it is best to populate all the build slots first for best performance.
If you use an E-ATX case it works just fine. I've never had a problem with supermicro boards not lining up to the E-ATX mounting holes.
Latvian Mailbag ?? Yay !

The Xeon has a quad channel memory controller in it so what you need to do is match voltage, rated speed, and capacity of at least 8 DIMMs if you're going to be using both sockets.
