Am I doing something wrong? I talked to our friend William Lee and about to send this board back to Asrock. I got PSU connected, 3 CPU ATX connected. I had basically gotten a second PSU as the first that I got had only 2 CPU cables included. All vendors have different connectors on PSU side I couldn’t find a spare for the Asrock PSU. So I got a new PSU with 3 CPU cables included, I tried a splitter at first, I thought that would just work. After getting everything connected I was hoping I would CPU readings but no luck. RDIMM from SK Hynix. After mocking around and flushing new BIOS and attempting to debug with redfish and ipmitool, no luck.
So sad, this board build looked promising for a nice workstation.
I don’t have this board/bundle (yet at least), but I’d be interested in a picture of the motherboard top-down so we can see all the power connections, also what PSU are you currently using? I’d also check the CPU voltage jumper to make sure its set to the correct voltage for the CPU you have (section 2.6 in the motherboard manual)
Is the 4pin in the top left from the 20 + 4pin cable from your PSU, or is it using the adapter included with the motherboard? Also I assume attempting to power it on doesn’t result in anything interesting in the ipmi?
you may want to try different slots for the ram as well, just in case something odd is going on with one of the ram channels
If you can compile a short list of things you’ve tried/verified that would be great too, just so we don’t go over stuff you’ve tried already
4pin top left is the one from the motherboard package. standoff on the bottom blue colored cap, I removed it. ipmi reads voltage from everything except CPU and memory. I tried to flush bios and, I had to send hex codex to unlock via ipmitool. I tried to factory reset couple of times as well. I had 4 sticks of memory in the beginning, but then trying only A1 slot.
Hm, I’d try putting the ram in different slots, if that doesn’t work I’d make sure that the screws that put pressure on the cpu have been screwed in all the way.
May want to also check the PSU side to make sure it’s ends are plugged into the correct places, and that they’re fully seated
Otherwise it looks like you may have got a DoA bundle unfortunately. I’m sure there are some other folks in this forum that have gotten this bundle so it may be worth seeing if they have any ideas before sending it back to Asrock (though it may be a day or so before folks can respond)
That’ll let you know if it’s maybe finding the DIMMs but refusing to work with them etc.
Also, since it’s caught me out - the CPU should appear to be ‘upside down’ in the socket - i.e. the lettering on it should be upside down when the motherboard is viewed from the bottom.
oh awesome, thanks, I will try on the next board, hopefully turnaround will be quick. I sent this board back already. yup, cpu is upside down if seated correctly, it’s a pretty heavy chip!
4800 DIMMs should be fine. Oh, another thing: did you use a torque screwdriver when installing the CPU and heatsink? I’ve found it’s important to get the torque correct otherwise it won’t boot.
hm, I used T20 screwdriver and used my hands, I did it in their recommended sequence (6-1, 1-6) when I was reseating cpu. It came preassembled with cpu installed and with a light touch of thermal paste, which I accidentally smudged on my palm lol. I am wondering if I should purchase a torque screwdriver
Hey! So I actually have this board and ran into the same problem. Couple things have to be done here:
First, the* middle jumper must be moved to the AmpereOne location (CPU VREF). This messes with memory.
Second, you need to check the 24 pin to 4 pin adapter, since it’s a pretty flimsy design and can depin. It also can be put in backwards despite keying.
Third and finally (this is the big one) you HAVE to connect the 6-pin graphics connector in the bottom. Previous Altra boards didn’t require this, but the AmpereOne board does.
Let me know if you have any other questions.
Edit: Oh, and make sure you flip the BMC Disabled jumper from its default location or this thing will take forever to boot. BMC doesn’t actually disable, it just tells the motherboard it’s allowed to boot without waiting for BMC to boot first.
Edit 2: One more thing, unless you’re workstation is going into a closet somewhere, that Dynatron W23 is going mean you’ll want noise cancelling headphones (another ask me how I know moment). The latest Arctic Freezer 4U-OneX is out online (at your favorite rainforest-themed seller) and it’s way quieter, with better cooling performance.
Once you get everything booted, let me know and I can also help you with operating systems, since even some Linux distros struggle to boot / install properly on AmpereOne.
Personally? I’ve found that Debian works best out of the box. Not as glamorous as a full HCI-type OS like Harvester, but it just works without complaining.
If you want, I could test both Talos and Harvester out and see what the install experience is like (since other distros, even ones that are more common like Fedora, have issues).
