Took motherboard out of chassis still same result. Very strange

Ok can try later. But that could explain why it's only with all 16? and why 16 2Rx4 works but not 2Rx8?

No POST, no lights on front of case.

@RageBone @RolloZ170 Update I can't get this issue to be persistant when testing different slots. I can fill 14/16 DIMMs and it might have this issue, switch some of the sticks around (same DIMM slots used) and then it may boot, making me think it's an issue with one of the sticks but I have...

Strange. If it's memory speed shouldn't the 2Rx4 2666 DIMMS also have this issue? I can't think/find what else to do...

Only thing I can find is Gyazo Screen Video - Modify memory clock? Changing clock to 2400 didn't change anything. Everything is still non responsive, holding the power button doesn't even turn it off I have to pull the plug.

Struggling to find POR for AMD in the BIOS. Found this Gyazo Screen Video BIOS is version 2.1c with 7002 CPU, it should be fine for 2933?

Both the 2Rx4 and 2Rx8 are 16GB. 2Rx8 are 2666 vs 2400 (2Rx4).

Would that be an issue when other RAM sticks are working fine? All 2Rx4 I've tested works. (1 CPU 16 DIMM)

They are not defective. The memory sticks pass MemTest+ if I only put 8 in (CPU 1 Blue) MTA18ASF2G72PDZ-2G6E1RI with AMD EPYC 7642. I only currently have 1 CPU so yes they work with CPU1 8 blue, it's just once I put CPU1 with 8 blue + 8 black the issue arises.

If there are plans to launch more EPYC 4004 at the end of the year/start next year I will wait for those (with same/better performance as Ryzen 8000 series) I've been holding off upgrading waiting for Ryzen 8000 for the performance increase. Ryzen has been stable for me.

So performance wise do we know if this will out perform Ryzen 8000?

Fairly new to understanding RAM is there a reason why I can't get the system to boot at all with 16 2Rx8 DIMMs, it seems be OK with 2Rx4 using 1CPU only H11DSU-iN | Motherboards | Super Micro Computer, Inc. 8 DIMM works fine (2Rx8) Post boot code ff completely blank screen. Front green LED...

I have fitted a H11DSU-iN into my 819U chassis now need to sort the 1U coolers. Only have experience using fan coolers. Is a passive cooler good enough for this? Supermicro fan snk-p0062p 1u h11 amd epyc 7000 sp3 cpu cooler | eBay - possible current option. I will be using high end TDP Rome...

Supermicro SYS-F618H6-FTPT+ look good. Does SM offer these trays that support EPYC 7002/7003 in that chassis? Thinking of long term upgrades
