Thanks for all the suggestions about the torque on the socket. The seller didn’t send me a torque wrench with my purchase. It is eBay after all. 😂 I do think I accidentally got the pressure right for the final mount considering that I got it to power up. However I will get an appropriate torque wrench for the follow up video.

[@grumbert]

what's the model of motherboard?

[@colestowing8695]

(copy pasta from another comment string) the early epic's were extremely sensitive to mounting pressures. Even mounting the heatsink could wind up screwing up memory channels etc. There's a pretty specific way you need to install the processors and hsf's. And yes, it can take a longgggg time to do memory training...like i seem to remember it could take upwards of 10-15 min or more sometimes (although you probably would have seen some signs of life if you got to the memory training phase). Anyway....looking forward to seeing you figure it out 👍 (Edit-you should send Wendell a message from "level 1 techs"...he lives and breathes this stuff. I'm sure he'd be happy to help you out)

[@WhiskyNerd]

yeah go ask Lius for one. He has like 10 of them.

[@flexxx222]

These CPU retention brackets need to be torqued to a specific spec. if that's not the case you could get bad contact on the pins of the socket to the CPU and that can end in a no-boot scenario. Usually, if you buy these CPUs ne, there is a tool included. That is missing in you case, Dawid. I suggest getting your hands on one of those tools ans try again.

[@DawidDoesTechStuff]

Thanks for the suggestion. Will definitely get an appropriate torque wrench for the follow up video.

[@the_wiki9408]

It honestly should still power on with NO heat sinks. It would just overheat and power off in 60 seconds.

[@Shire_Sam]

Also remember that server hardware takes a LONG time to fire up properly. I noticed at the front there was a little green light flashing? Did that give you an error code of some type? Did you try plugging a monitor into the onboard VGA to see if that gave you an output? I'm not sure if it was AMD CPUS but at some point they (HP or Dell I think) started locking CPUS to specific motherboards so that they would only work in that specific combination. Thank you for such entertaining videos good sir 🫡

The network port above the USB plugs is ipmi I believe, you should be able to plug that in, then go to the IP address that gets assigned to it in a web browser and log in and the board will probably tell you what's wrong, and you should be able to power it on from there as well.

[@reinekewf7987]

[@FarrellMcGovern]

I was going to say the same thing. I used to support huge racks of servers, including dual CPU Epyc, Intel, Power6 (and above) AIX, HP-UX, and all those other fun letters. IPMI port needs to be connected to a system and booted through it to do the initial setup. You can then configure the MB to boot directly to the internal media, that is what those USB and SDcard connectors on the MB are for. You would, for example, have VMware installed on a USB Stick or SDcard, and boot from it, then either have internal HDs, or space on a SAN/NAS/SAS that would have all the virtual machines and such. Lots of fun...yes, I am strange. 🙂

[@phillipscards]

Dawid, those cpu socket lid screws have to be torqued for the cpu to make contact with the pins. They usually have an included torx wrench.

[@b127_1]

Keep in mind that you have to use the VGA out. It might be different now, but for my Supermicro board, the VGA is the only way to get into bios. In all of its 640x480 glory. A GPU will work fine in windows, but until windows boots, it doesn't show anything for me.

[@jonlangfitt]

Ah yes, supermicro. When I started getting back into PCs right before the dark period between rx4-500, I started out with free trash 771 workstations as my younger coworker was really into XP - 7 era stuff. For years he was always pushing supermicro for compatibility. I had a couple over the years but they were never more than 2 memory slots and were basic boards. The one supermicro board I kept was an mATX 1150 board for a NAS that i wanted more than just 1 x16 and 2-3 x1 as I was running sas cards and wanted at least x4 on two. I also already had a shit ton of various DDR3. The board claimed to work with the i3, celerons and E3 xeons, but not the i5-i7s. The single 1150 i5 I had came before the xeon and wouldn't post, but i had another 1150 board coming for my kid's PC at the time (hence the i5 while i waited for the xeon in the mail). His board had a couple of pins smashed down I was able to re-articulate with micro tweezers. Put in the 'tested' i5. No post. Start the process for returning the motherboard, seller is fine with taking it back, the e3-1230v3 arrives. Before I ship the bad pin board I put it in. Posts immediately. I end up getting another i5 that comes up later. So in the meantime my kid has my nas cpu and my coworker insists that supermicros limited ram compatibility for my particular board is near imaginary. I get the i5 in and swap it into his PC. I put my generic 1333 ecc dell memory that usually works with everything else, no post. I try some matched crucial, no post. I try my all of my 1600 sticks individually, only one stick of random 2GB works. I sell it off to my coworker as he swears he'll get it with his sticks. He ends up going through several sets with the similar results with memory from his server and workstation stash. I end up buying it back to give it another go. The listed sets that were supported were hard to find secondhand except for one set. I bit the bullet and bought the RAM, but then put my nas off until I found a 4 U case I liked and gathered SFP+ equipment. Time passes, I swap the i5 out for another i7 equivalent xeon and pair it with my old rx580 to my kids pc during a case upgrade. For fun I put the i5 in the supermicro with random non ecc memory. Forums, cpu support and bios update documentation all claim the i5-i7 aren't supported. Fucking thing posts. I still have it to this very day, I doubt I'll ever get rid of it willingly, even though I low key hate it lol Only supermicro board I've ever had issues like that with, but damn was it a bad taste compared to their 2011 and 1156-55 boards I'd used prior.

Before Power On 1. Check that the LEDM1 is blinking before the motherboard is turned on. 2. Check that the LED3 on the motherboard is on. 3. Make sure that the power connector is connected to your power supply. 4. Make sure that no short circuits exist between the motherboard and chassis. 5. Disconnect all cables from the motherboard, including those for the keyboard and mouse. 6. Remove all add-on cards. 7. Install a CPU, a heatsink, and at least one DIMM on the motherboard. Check all jumper settings properly. Make sure that the heatsink is fully seated. 8. Use the correct type of onboard CMOS battery (CR2032) as recommended by the manufacturer. To avoid possible explosion, do not install the CMOS battery upside down. No Power 1. Make sure that no short circuits exist between the motherboard and the chassis. 2. Verify that all jumpers are set to their default positions. 3. Turn the power switch on and off to test the system. 4. The battery on your motherboard may be old. Check to verify that it still supplies ~3VDC. If it does not, replace it with a new one Manual Fro SuperMicro

2:10 one of those network ports will likely also be a remote management port: a computer in the computer that hosts a webpage that lets you start, stop, and reboot the computer. It will _probably_ also let you remotely control the computer but ymmv on if you need an ancient version of Java filled with security holes to run it. These management ports typically have diagnostic information such as voltages from the power supply, fan RPM, and sometimes what CPUs+memory configuration it sees.

Be sure that the board and CPUs are compatible. Some of those server boards only work with certain CPUs. You may also want to try going IPMI into it if the board supports it or going in the VGA/Mesozoi port.

[@rayproductionsbackupchanne3862]

1 yes you need the torque wrench and 2. the memory training takes LOOONG so just give it a solid 2 to 3 minutes once you got it torqued right

[@moddaudio]

You may want to try the VGA port on the motherboard. Server boards usually have an aspeed video chip and dedicated network port so you can remotely change bios settings over ethernet. It has to get though that nonsense before it even thinks about booting the cpu.

[@harshbarj]

You must use the supplied torque wrench to get the system working. Sadly being used you did not get this. But they are only ~20 USD. Without it the CPU is likely twisted in the socket with pins not making contact. These are a behemoth of a CPU that must be secured properly.

[@guaripolo69]

yeah as mentioned before i strongly believe that is the CPUs not making proper contact since these need to be torqued with the bright orange thingy they include when new.

Jesus dude the way you screw the cpus down made me hurt inside you have to carefully turn each screw a step at a time to apply even force across the cpu onto the board.

[@gefoz5332]

I think I've seen this issue before.... It's because supermicro uses their weird proprietory connector which fit in x16 but actually pcie x8 with different output lanes so that a normal pcie device couldn't work. The connector is used for a storage such as SATA and NVME. I've seen the converter to a normal pcie but I never tried it. This problem also happened to my old supermicro server, the difference is I'm still using lga 2011.

[@Gokul_Yt]

If cpu isnt mounted correctly it may do that that also explains why it booted for a second there. These sockets do require a lot of mounting pressure so maybe you have to really screw it down (I think they come with a Torque driver and recomanded specs). The board has ipmi so trying that would be the first thing you should do.

[@shaunrattee224]

Those CPUs need to be correctly torqued like the threadripper or they won't work.

[@HR-wd6cw]

In those types of motherboards, I believe you have to run dual CPUs or install a continuity module for the "empty" CPU socket. it does sound like one of the CPUs was dead though if you weren't getting any power with just one, or possibly one of the sockets on the board is bad.

[@aljosamlinaric8705]

Seems like torx bit that you used for tightening down CPU to the socket, was little to big. Might be that you didn't tighten those three torx screws enough.

[@Torbjorn.Lindgren]

It could be a pressure issue, the three retaining screws on EPYC and Threadripper sockets must be torqued down to a fairly specific amount - if you get the torque wrong (and yes, too high is also wrong!) some or all of the memory channels and/or PCI channels often won't work so that's another possible reason though usually at least ThreadRippers tends to get to the BIOS screen. But since it's a server they MAY have decided you're supposed to check the BMC information for that instead.... The ASPEED Baseboard Management Controller runs completely independent of everything else and you connect to it via the dedicated (third) network port. That should be your first place to check. All Threadripper retail packages includes a yellow bespoke torque-controlled torx screwdriver that goes "click" when you hit the right amount so they're fairly easy and cheap to get on the second-hand market. I've seen blue ones that presumably comes with at least some EPYC processors (matches the 7xx1 carrier board color) but a EPYC one should work. It's NOT impossible to do this without a torque wrench but it's definitely not trivial even if you've done it many times! Looking at SuperMicros memory list I'll note that it's VERY small but also that all the few 16GB sticks it does list are 1Rx8 models, not 2Rx4 like the ones you bought. It does have some larger 2Rx4 sticks so it clearly supports x4 chips which means those memory sticks MIGHT be supported but... risky. From any of the other large vendors the manual would spell out exactly what memory is supported but not with SuperMicro... The other source is various memory vendor memory configurators - Crucial only show 1Rx8 models for 16GB but that might be because the memory chips required for 2Rx4 is, well, long since out of production and they're selling new memory. Kingston's Memory Configurator usually has a side-bar telling you what the hardware supports (in addition to "these current server memory sticks will work) which is really neat but... their entire site is down for maintenance Sigh. The manual does say how to officially run it just one memory stick and one CPU (and 2/4/8) but two cpus officially needs all 16 memory slots populated, I expect this is completely bogus.

[@Movingfrag]

From what i see it most likely a torque issue - these CPUs require a lot of torque on the socket screws, it is by no mean "finger tight". I do not think that it is a memory or cpu vendor lock issue because these manifest much later and you would see the fans spinning. To this theory the bad spread of thermal paste adds up as well - looks like cooler bottomed out on the socket instead of the CPU itself. Also, in order to get more information - assuming you just apply more force to screws - just connect an external VGA display to this mesozoic port, these boards come with IPMI management chip (it is active since it blinks green when board is fully powered and it booted up) and it starts outputting debug information to the onboard VGA before it even initializes PCIe devices so you will get information much sooner.

[@PauloHaas]

Not sure if that changed on Epyc, but you will usually not get POST with CPUs installed but no memory. Also, server motherboards usually require the correct memory positions to be filled - so please double check in the manual. Easist process is to start with just one CPU and the least amount of memory possible, then start changing memory modules untill you have any signal. Like other people commented, server motherboards can take a long amount of time to do anything. Another thing that comes to mind, maybe the BIOS is not updated for this specific CPU? That would be problematic because you would need a supported CPU in order to boot and uptade BIOS. Well, good luck! Part of the fun is getting it to work :)

[@atefamriche9531]

happy to help you figure this out as there were quite a few things done incorrectly in the video. - CPU mounting: the cpu has to click in with those blue tabs then you put the retention bracket and torque it to spec (must have tool for that, comes with threadripper CPUs typically, not sure about epyc). Thermal past application, use 9 dots at least - RAM: do NOT EVER use non-ecc on server mainboards. check carefully online and the manual to confirm compatibility. Check manual for which RAM slots to use if not fully populated. You can fry normal DDR4 sticks if mounted in server. - you don't need a GPU, you can connect a VGA monitor to see the bios screen and get the IPMI IP address. There is like a small computer within the mainboard that manages the big PC and gets you plenty information about your components (without even booting the PC). I think those flashing green lights mean it is powered on and ready to use. - The Ethernet ports are not all for the PC. One of them is for the IMPI remote management system. Make sure to check which one that is (manual again) then connect it to ethernet to be able to use remote access. - use the IP address displayed in bios boot screen. type it in your browser, then you can access the ipmi. - remember that it takes a couple of minutes for the on-board IPMI (small computer on the mainboard) to boot up. hope this helps. There are a few more precautions. reach out if you'd like some more help. This hardware is tricky to get running. Once you do, you can add multiple GPUs, everything will run at full speed as you have a ton of PCIE lanes

The torque on the cpu and heatsink needs to be 1.4 Nm.(just use a t15 bit and electric screw machine) Also if you connect by ipmi you can check sel log ( useful if you get errors) can check sensors and more. (you can use a serial cable for it it believe)

[@lucidnonsense942]

If this was run in a server, you might need to set up a console via the management port and tell it to turn on. It could be that it's just waiting for the command to start up. Turning on a server board just starts to initialise the management subsystem, think of it as turning on the computer that will turn on the computer.

[@TonyHoyle]

You should be able to see what's going on from the IPMI.. that's essentially a small computer which is independent of the rest of the system and will tell you exactly what the board diagnostics are saying, even if it's 'your CPU is toast'. Basically plug a network cable into the IPMI port and see if you get lights.. then hope you got the password..

5:23 not enough thermal paste, that is ~50% of what you really need.

[@Kevin15673]

4:06 bro was really amazed a screwdriver set had torx bits

[@eldibs]

"Okay, so. Big problem, I didn't do enough research going into this video. Which is quite normal..." Dawid is rocking that self-awareness.

[@TheSergio-re2hs]

the com conector is used for server management purposes

[@fragalot]

Dawid, I see you understood the need for a proper torque tool for installing these CPUs. Threadripper CPUs also have the same thing. I am not sure if the torque needed a for Threadripper CPU is the same for Epyc CPUIs do. So you might need to get a torque that is specific for Socket SP3 (not TR1/Threadripper), as the ones for TR1 might have a different torque spec. I'm not actually sure about that, but using the wrong tool could break something. Even with the proper torque, you can still have issues if the CPU is warped, or the socket is warped.

[@lerouxvermeulen4403]

I love it when Dawid Does Tech Stuff!

[@kikihun9726]

Make sure all the jumpers are in their default configuration. But you should get a torquewrench. But you can try to login trough the ipmi port. It is always on even with no cpu.

[@dmagik8]

I NEED to do Dawid with a silly machine doing dastardly things to it. That is all. Love the channel.

[@davidrains6751]

hell yeah lets gooo the next videos on this server stuff will be so freakin awesome

[@ZeroX252]

Enough people have already pointed out the need to properly torque the socket retention - but you may still require multiple attempts after getting the right torque tool. The EPYC SP3 carrier and tolerances were "pretty bad" to the point that even now, most board vendors sell the board with a CPU preinstalled and guaranteed to POST. From there, server boards like that one have a BMC (Baseboard Management Controller) which is basically a full low power PC similar to a raspberry pi that runs a low resource OS and hosts an out of band management interface accessible in a web browser. This interface lets you mount disc images for software and driver installation, view the screen and input keyboard and mouse inputs, as well as turn the server off and on as if you were standing in front of it. That BMC can take QUITE a long time to boot (up to FIVE MINUTES) so its worth just leaving the server off but plugged in with the power supply on for a bit. The BMC will stay in a low power initialized state for quite a while on the 3.3v battery, but will eventually fully shut down again abd require that startup again.

[@slightlytango9741]

If you ever want to sink your teeth into it, look into xeon e7's, with the 8 prefix. You can find some old ones with pretty high core counts for just.. nothing. Something like 20-40$. You can put eight of those bad boys on a single motherboard. The only motherboards I have found though that have it, are blade motherboards, so you would have to figure that whole mess out in terms of powering it ;). But might be fun?

[@Shankaporomous]

Good luck hope you work with servers before, that cpu and the tread ripper are server based , accessing as someone mention has to be done via the network port, good luck can’t wait to see if you can get it working

[@tokul76]

Added video card when builtin video is present. "Resetting cmos" when CMOS battery is missing. It is server board. There is nothing fancy about 2 lan + 1 management lan.

[@timtim2949]

0:10 : **dying Arnold Schwarzenegger noises**

[@makuIa]

i’ve used ebay a total of 4 times in my entire life & i’ve legitimately been happy with it once. i’m actually shocked & equally impressed it’s managed to survive so long

[@safetinspector2]

Motherboard SDCard: in servers it is sometimes used as a boot device for a lightweight hyper visor such as VMWare.

[@Smakheed]

I noticed you never torqued down the 3 screws for the CPU frames... THIS IS CRITICAL to ensuring the CPUs are contacting the pins corectly.

[@killerful]

We're gonna need to call in backup from Wendell

[@johanneskaramossov5103]

Nice to see you have fun with those, in case you are wondering those SD cards are sometimes used for OS on setups where you need no storage just compute.. anyway using a single 7702p mainly for pcie 4 and for more pcie on the MBbut first gen are alot cheaper per core but older servers are often a ton of bang for the buck!(if you dont need insane single core). Also said it didnt work out usually i pay like 20% more to buy it of local sellers because i trust those more but hey even there sometimes you get things that dont work.

[@MatthewSuffidy]

Hate to say it, but I am glad that was your voyage and not mine. Would have been a killer system though. Sometimes you can con them if there is just a burnt out fuse or something on the board. You definately want to be careful trying to screwdriver complete the on switch that it correct and you don't hit anything. Also I would not put a super heavy card in before bracing it in the case somehow.

[@masterviper420]

did any one look at the blinking green led maybe thats telling u a post code i would start their

[@rustler08]

Lol, I immediately saw the lack of torque wrench and cringed. I'm not even 5 minutes in

[@florider_hd]

as soon as is saw him putting in those cpus i knew the contact would be terrible. im sure hell be fine in the follow up
