New motherboard not working

the picture of the cpu in its carrier, notice on the right side the carrier clip is touching the cpu pads,, when the cpu is installed are the clips fully clear to allow the cpu to make full contact with the socket, code 00 means either bad cpu or no cpu detected, make sure to refer to the mobo manual and check your using the right socket if only uisng 1 cpu to test, with ram only put the least amount possible to check channels, then add more until it goes bad, when it does you can narrow down the problem.

if ram channels are not working from the outset then check the cpu's again, mounting pressure is critical and check the carriers too

official ram speed for your 5512U xeons is 4800mhz 1dpc (8 ram sticks) or 4400mhz 2dpc (16 ram sticks)

The fitting of the cpu in the carriers is something that’s not 100% clear, I followed one of the YouTube guides for a LGA4677 cpu. Apparently the outer row or two of the cpu pins are unconnected. Might take the coolers off and try fitting the cpus again.
The code 00 is shown initially then it quickly changes to 10 which apparently means something like PEI initialisation whatever that is. At that stage it shuts down.
The memory speed is confusing, some say 4800 but crucial and Kingston say 5600 is ok. As a last resort I’ll buy a couple of 4800 RDIMMs from Amazon and then I can send them back if it makes no difference.

OK so with no USB devices connected, still the same.

I did a bit more testing with just the mobo and psu (a thermaltake 1200)

First with just CPU1 and a pair of DRAM for it - as before, on power up LEDs go from 00 to 10, then red CATERR1 led comes on and the psu shuts down.
Then removed all DRAM - just the cpu. Exactly the same.
Lastly removed the CPU as well... of course pressing ppower on does nothing.

See the pic at https://www.peardrop.co.uk/IMG_5938.jpg for the setup. No, that antistatic bag is not conductive, I tested it.

What to conclude?
- Possibly the DRAM is incorrect as taking it out made no difference
- Other possibility is the CPU is incompatible with the mobo?

I'm leaning towards the first i.e. DDR5-5600 is incompatible with the mobo/cpus but appreciate others thoughts before going out and buying a couple of DDR-4800 to test that theory.

Question: I'm assuming those power connectors at the top that are unconnected and marked 'GPU' are to connect to a GPU? Or do they need to be connected to the PSU??? It's not clear in the docs, my last mobo only had the 24 pin ATX power and two 8 pin CPU power sockets.
 
The connections marked GPU at the top of the board, I would assume they need to be used regardless, when you have 2 cpus installed the eps 8pins have a combined 300w, the extra plugs would provide an additional 225w of power to the cpus, plug them in and see if it'll power up and post.
 
Looking at the Asus manual for the Z13PE-D16, it says 'GPU Power Connectors (8 pin GPU_12V1/2). These connectors are for supplying power to installed GPU cards'. From that I would ahve thought they supply power to gpus, not receive it from the psu?
 
Well a quick try indicated no difference, so that ones out too.

About the memory speed, Asus say:

Z13PE-D16

ASUS Z13PE-D16 server motherboard for dual 4th Gen Intel Xeon Scalable CPUs, with single-CPU support for three PCIe cards, 16 DIMM DDR5, dual M.2 and integrated ASUS ASMB11-iKVM.

Now does that mean DDR5-4800 only is supported or is DDR5-5600? Its as clear as mud.

official supoport looks to be 4800mhz, but ram speed is dependent on the cpu's, the higher end cpu models may indeed support fatser speed ram as they are the best of the best silicone

looking over your cpus (5512u) they support ddr5 4800mhz max, if you look at the 6554s on the otherhand that chip has official support for 5200mhz max, every cpu in the xeon gold range has diffrent memory max support but the max suppoorted speed i've been able to see is 5200mhz.

if you look at the platinum series of xeons especially the plat 8592+ xeon that cpu has support for 5600mhz ram but only in 8 channel config

Yes the Intel spec for the 5512U says 4800 (https://www.intel.com/content/www/u...ssor-52-5m-cache-2-10-ghz/specifications.html). Seems like only a few 5th gen xeons officially go up to 5600. I'm sure I read somewhere that the cpu controlled the speed and if it did not support 5600 would throttle back to 4800. But maybe not.

So I've ordered a couple of Micron DDR5-4800 RDIMMs to try. If they work, great, if not... then I've got a lot of expensive trash here.

Just out of curiosity did you consider threadripper/epyc, a single socket solution from team red would be a very compelling option vs intel.

I guess I'd been a happy dual Xeon user for the last 20 years, which worked great for running VMWare - typically 8 linux VMs at once - but yeah, this does make me wonder.

Ah fair enough, the later gen threadripper/epyc have really hurt intels xeons, though intels latest sapphire rapids xeons are clawing back some ground, performance is good but efficiency is some what lacking against amd still
 
Yes my current setup which I put together in 2016 is an Asus Z10PE-D16 WS with twin E5-2640's and 256Gb memory, its been working flawlessly ever since although starting to show its age a little and won't run W11. It worked first time so naturally I had high hopes for moving to a similar but newer mobo and cpus. Alas its been a nightmare.
 
Well gues what. I think it may be nearly working now.

It was suggested by the mobo seller that it may need the BIOS updating (why, you may ask, are they being sold without the latest updates?). How do you update the bios, if you can't pass POST? Well on the Asus board there is a 3rd ethernet port for server management. They suggested hooking this up to the network , finding the IP of the port, and logging in with a web browser.

The hardest bit was finding the IP address. At first I just saw my old server, but after a bit of trial and error was able to log into the management port and run iKVM, and there was the option to update the bios. With version 2204 on the local PC it was simple to flash a copy to the mobo.

With the bios updated, it's now possible to boot into the BIOS. It's not completely working, I seem to have a couple of issues:
- seems to be only recognising 128Gb RAM
- seems to be only finding 1 processor
- After POST says it can't see the NVMe device (there are 2 NVMe's, the boot one has a clone of a WIndows10 disk on it).

Hopefully these can be sorted out tomorrow...
 
all you have to do is remove the protective cover and drop the CPUs into the sockets

Nooooooo.. There is a very very special way to install Xeon CPUS. You have to use the specific intel cradle for the CPUs you are using (The motherboard will come with them and to check you have the right ones you have to go to the Intel Ark and it will show you which cradle you need, in your case its E1B, you get the correct ones from the motherboard box, fix the CPU into that cradle, then attach to the COOLER, then install into the motherboard in a very specific manor.

Here is a installation guide.
You have to be very careful with the amount of torque used and the cradle used or it will cause memory not to be recognised or damage to the socket.

Gone are the days where you plonk the CPU in the socket, stick the cooler on and tighten down and you are done.
