New motherboard not working

So I'vbe been collecting the parts to build a new server/PC, using the case (a rather massive phanteks thing) of my old one I built some 8 years ago. That used a Asus Z10PE-D16 WS, the new motherboard is a Z13PE-D16. I have a Micron 2Tb NVM SSD with the old PC OS on it, new Crucial DDR5-5600 memory and two shiny new 5512U Xeons. Kept the existing 1000W EVGA power supply.

Spent some time today stuffing the new motherboard with the memory and cpus and checking the connections. Then went and powered on.

The fans came on (both CPU fans and case fans) but within 2 seconds it shut itself down...

Looking a bit more closely at the LEDs on the board:
- the standby power green LED blinks green as expected
- the Q-Code LED indicated 00 then 10 before the shutdown, apparently 10 means 'PEI Core is started' whatever that means
- the green DIMM LED briefly goes green when power is applied indicating there is 12V power to the memories
- a red LED next to the styandby power one comes on very briefly at the moment of shutdown. I think this is the 'Processor Catastrophic Error' LED.

So I'm kind of stuck. I did try taking the board out and checking there were no shorts on the back to standoffs, and the testing is without any SATA/USB connections or PCIe cards. I've checked the memories are in the right slots, the only thing I can think of now is something wrong with the CPUs? They are LGA4677 ones which is new to me but they seemed to drop in OK and fitting Noctua coolers was straightforward.

Any suggestions appreciated!
 
According to the order, memory is Micron it seems:

32GB DDR5-5600 RDIMM MTC20F2085S1RC56BR 2Rx8

I should add I get no system beeps as this motherboard doesn't have any kind of speaker/buzzer!

Was the old system the same mobo as this new one?
might be the problem...maybe

Old system had a different mobo, it was an Asus Z10PE-D16 WS. What I had planned was to replace the complete mob including DRAM, NVMe, memory with the new board which has new CPUs, DRAM and NVMe.

I'm hazarding a guess the CPUs are working but the fail at the PEI stage is due to memory. The memory is in the right slots and seated correctly. I believe the CPUs are seated OK, as if I take them out nothing happens at all if I power up the mobo.

Asus say 4800 RDIMMs for the Z13PE-D16 but I have 5600 RDIMMs, could that be an issue?

Will it boot to bios WITHOUT the SSD?
I think dimms will default to `jedec` speeds.not sure
Tried clearing the cmos?

I'll give it a try but I don't think it gets anywhere near trying to boot the bios. As the 'CATERR1' LED briefly lights before shutdown - it seems there is something fundamental with the hardware.
 
Removing the SSD had no effect, it never gets that far. I’m more and more thinking it doesn’t like the memory, I took the CPU’s out and reinstalled them, double checking they were the right way etc. I guess the other possibility is the power supply but it’s a 1000w one and was fine with the old mobo.
 
Ouch, I'm gutted. Scan say both CPU sockets have damaged pins and so cannot be exchanged or refunded. Well, I'm not aware of damaging them during installation - all you have to do is remove the protective cover and drop the CPUs into the sockets. And I'm a bit OCD about handling a board that cost over a grand. I believe the damage was there by the time it was delivered, although I don't have any proof of that (and Scan does not inspect boards prior to shipment).
Not sure what to do... they will see if they can get an exchange from Asus (do I see a pink thing flying?)

No chance Asus will exchange it for bent pins.

There's a guy on here that mite be able to sort the pins for you but I can't remember his name, I'll tag a few guys in see if they can remember.

Mite be @Vince

Yeah, I guess its possible. It must be very easy to bend pins, the last board I put together had LGA2011's and had no issue with.

Scan are being very helpful and have said they'll try for a return with Asus. If not they believe they can repair it. Fingers crossed.

I'd always take a couple of high resolution pictures of the socket prior to a return, with your name/username and the date/time on a piece of paper near the motherboard.

It is unfortunately not unheard of for retailers to try it on, but I won't say anymore because we're not supposed to mention competitors here. You can look up the stories yourself if you want to.
 
Well, it wasn't the motherboard. I have a replacement and the problem is exactly the same. So I guess it narrows it down to:
- cpus. Seems unlikely both would have failed.
- memory. Crucial tell me the memory is compatible with the motherboard, though.
- power supply. It's an EVGA 1000W one, that works fine with my old motherboard.

Bit stumped as to what else could be causing it to fail!
 
Have you/can you try with just single CPU installed? Unlikely but would be dead unless the socket issue killed them but again, BOTH?
 
I did try that with the previous mobo, but can try again. I am wondering if the cpu is not connecting to the pins, the LGA4677 has a plastic carrier that you fit the cpu into, attach the cooler then fit onto the socket. Although it seems to fit into the carrier OK (there is only one way it can go, and the triangles line up between cpu and coard) it has got me wondering.
 
How the devil do you post images? There is an 'Insert Image' icon but it doesn't want to upload a web link I give it, notr is there any means of dropping an image in this post as far as I can see.

So I'll resort to the old fashioned way, sigh:

https://www.peardrop.co.uk/IMG_5936.jpg - this is a pic of the socket. All pins look good.
https://www.peardrop.co.uk/IMG_5937.jpg - a pic of the CPU in its carrier. If you look really carefully you can just about see the marks the pins have made on the cpu pins, right in the middle of them. So it does appear to be making contact.
