And what you have and haven't tried yet.
First thing you don't wanna do is check the pin grid array of the cpu with a magnifying glass for anything that looks defective. You'll need a strong one 10x would be a good starting point. That's if you even have one. For me this is proof hell exists. It's a forest of golden pins. Of course removing the heat sink and cpu and replacing it several times increases the hazard too.
The ram might be compatible with 'the other processor' but not the 5950x.
For troubleshooting purposes you could try disconnecting all other peripherals so only the gpu, cpu, mobo and mem are connected. Then if you have a different memory kit anywhere? Try that instead. Try the gpu in another slot see if the system will p.o.s.t.
You can also check userbenchmark to see if others are running a system with the same board and mem as yours and a 5950x successfully. So you have to dig around on some of the other results to find the info you're looking for I haven't found an easy way to search it apart from going down the list, bit tedious. That's one way of looking to see if your non compliant memory can work with this board and cpu combo.
And of course you have to navigate the site and find 'the list' I'm referring to. Other results... of the same memory. I mean you can click under the title of your memory in your userbm results where it says X User benchmarks in blue and get to where it says ...and X more results... there will be a list of those using the same memory. It's not too great a roll of the dice that some of them will have the same mobo and cpu combo you're looking for. It might be good just to confirm it. I mean it's not 100% reliable since memory part numbers can be reused with different dimm varieties sometimes but it can be a good indicator if you're searching for 2 hours and find nothing with your combo
So why don't I just post the page I'm talking about? If it works:
https://cpu.userbenchmark.com/AMD-Ryzen-9-5950X/Rating/4086
So that is a list of everyone using a 5950x who tested it there .
After a bit of navigating I found a list of everyone's whose tested their pc with this board on the site:
https://www.userbenchmark.com/System/Asus-ROG-STRIX-B550-E-GAMING/192498
now somewhere in the 5950x results is someone whose tested your ram kit with this cpu and board- just to prove it can work.
How you might be able to get that info:
https://www.userbenchmark.com/PCBuilder/Custom/S192498-M1340810vsS0-M?tab=MBD Use the userbenchmark pc builder. When it's known what your memory part number is we can see if anyone else has built one similar and it works. That may clear up any memory compatibility questions. So about 2700 users have this board and tested it there.
There is a sprinkling of 5950x users with it. Their pc must have booted to run pc benchmark, y or n? the answer must be Y. So the cpu can at least work 'that long enough' with this cpu in case anyone says muh but this board isn't ideal for it.. etc.
There is also a rash of similar posts on a variety of forums about people having trouble booting a 5950x on asus am4+ boards some went back to earlier bioses that supported the 5000 series rather than the newest. But generally inconclusive of what a precise resolution was for any combination of circumstances That could also be problematic in different directions eg. security updates and mem compatibility. . But tempororarily might be ok to establish if the board can be made to p.o.s.t with this cpu and mem combo. somehow.
Don't have to take my word for it:
https://www.google.com/search?q=Asus+B550-E+and+5950X+error+code+90+ ..
There's a variety of similar probs across a variety of asus boards here. See for yourself that gettin a straight answer would be easier if you talked to a rock.
Got another am4+ board anywhere you can try it in? As I say searching this your error code 90 shows a variety of inconclusive posts around this issue.
If you can list your spec. I can at least offer to search userbenchmark for a bit for the exact blend - has anyone else succeeded with this configuration could be handy to know.
A simple solution that doesn't involve juggling hardware around may not be in evidence. Tentatively could be a power supply issue good contender that is. Don't forget to include your power supply unit make model partnumber brand details wattage any specs you can see on the label in the parts list. The 5950x probly has a heavier power draw than 'your other cpu'.

oh yes and not to forget if you switch out the psu and it's of modular variety you must remove all the old cables as well eg. gpu pci-e connector, molexes for disk drives etc they are NOT compatible between different models of power supply. All the old power supply cables must go and do not get them mixed up with the new different better power supply.

Thanks for your detailed reply.
I've tried another PSU and it's still the same, the other PSU had a cable for eatx12v_2 but still the same. That's a Corsair hx520w with no GPU plugged in so it should have enough juice to at least post it. The PSU for the rig is a hx1000. The other CPU I tried was the 5900x and that worked fine.
I've tried taking different ram modules out. I've taken the CPU out, taken the repasted it and tried again it's still the same. I've only connected the MB, CPU and RAM to rule out anything else and it's the same error.
I've taken a pic of the pins:

To me they look okay.
The ram is cmk8gx4m2a2666c16 2x4gb. And cmk32gx4m2e3200c16 2x32gb.
I don't have another mb to try this on but if you think its worth a shot I can try get hold of one.
Thanks
oh you have mixed 2 ram kits? Try removing one of them that could be it 2 kits can be incompatible so maybe it's just ok with one cpu and not the other see here they are two different speed ratings as well so you can't have xmp on - this can just be due to 'the silicon lottery' so simply remove the two cmk8gx3m2a2666 2x4gb try booting with only cmk32gx4m2e3200c16 2x32gb installed in dimm slots a2&b2
' That's a Corsair hx520w with no GPU plugged in' ay what there's no igpu in those cpus so you can't post without a gpu installed but a 520w psu is probly a bit on the lame side for a 5950x. The regular hx 1000 psu sounds fine anyway if a bit overkill. PGA looks good in the photo -

Thanks for the reply.
I've tried doing that just now. It's still the same, I tried also doing the 8gb kit in a2 and b2 and it's the same. I tried resetting the CMOS while the 32gb kit was in.
Any more ideas please?
Thanks
Just now no, it's not made a difference with it installed or not. It still goes to error 90 with the VGA light lit up. For comparison with the 5900x it doesn't error even without a GPU installed.
yeah but the board will never post without a gpu installed. Vga light on/off is only telling you no gpu present. We wanna see if you can power on and it boots up I'm losing track of what's going on here also just try too boot with the gpu installed and everything plugged in with the hx1000 psu and only the cmk32gx4m2e3200c16 2x32gb, you don't wanna be using only 8gb with a 5900 or 5950 likely anyway. whose idea was it to install cmk8gx3m2a2666 2x4gb with it for what purpose? We must purge such ideas.

Back to the original question regarding the CPU, it can certainly be defective and that seems likely at this point.
In reference to removing GPUs, this system will do nothing (using either CPU previously mentioned) without a GPU installed. One must be present for the system to boot.

Okay.
I've done that. It's still the same. The ram idea not mine lol it came like that.
so last resort clear cmos though the system should automatically reset to defaults when the cpu is swapped. Ok so yeah it's poss the cpu is doa if there's nothing else you can do just be satisfied you tried everything you could. The pin grid array looks perfect so there may be a story of what happened to the cpu between the factory and here dunno if Hercule Poirot himself could unravel it.
also a search of your ram suggests cmk32gx4m2e3200c16 is a 32gb kit why do you think it's 64gb? Corsair vengeance lpx 32gb is the result I get from googlin the part number.

In any case there are 3 builds that appear to have tested this combo in userbm. So 'theoretically' it should work. Saying that 3 builds out of millions is not a lot and there could be a reason for that so it could be a niggling question of ram compatibility. Depends if the cpu is brand new or second hand and don't know where it's been.
Checked the mobo memory support list:
cmk32gx4m2e3200c16 isn't on it but close variants are . So that could mean hit or miss memory compatibility. It could mean the qvl is also out of date and subsequent batches of memory have been produced since it was forumulated. But that's not the same as certainly compliant as proved by the board manufacturer.
Also some of the 3600mhz vengeance lpx show better results and lower latency in userbenchmark. That's expected since you hit the 1:1 fclk ratio with the ryzen infinity fabric which does just that reduces the latency and improves ram access speeds. The 3200mhz kits look quite avoided. So I'm thinking that you thought your pc was slowish and wanted to amp it up with a better cpu unaware that the memory xmp wasn't enabled and only running at 2400mhz.
You seem to think there's 64gb of ram - the qvl confirms this kit is only 32gb (similar nomenclature on variations of the kit) if it was 64gb it would read cmk64gx... so whoever put those 2 4gb dimms in there may have been trying to fleece you on the ram thinking you wouldn't notice. If you tend to boot the system with the mobo logo displayed instead of the post screen it wouldn't be immediately obvious. I always disable the logo on startup it's an annoyance to my mind.
Since I'm from the days when they didn't do that. I just prefer the post screen.
So there's more than 1 issue going on here and it's kinda distracting since they've bundled one of the poorer performing kits with it anyway and not given you the presumably advertised 64gb but only 40gb. 32gb is more than enough for general usage even 16gb gets along fine word processing and gaming. 64gb is more for productivity tasks like 3d rendering/photoshopping/video editing and they've given you 40gb of mismatched non compliant slow ram. This seems like an explanation of why you thought the system needed a cpu upgrade.
It could also follow that if you got the 5950x cpu at the same dodgy place as the pc... so you sure it was sealed and not tampered with or anything? I dunno if they've even mastered the art of making the label look sealed.

Thanks for your replies!
Some of it made me chuckle. I know it's a 40gb ram kit, sorry if I confused you or wrote it wrong. I didn't know that the ram speeds were different though, so I'm assuming it's going to run at the slower speed kit speeds. I got a bundle and then the 5950x with the idea that I'll sell the 5900x and keep the 5950x.
I tried resetting the CMOS like you said but it's the same. I might return the CPU at this point.
ok well none of those ideas will really work well. Resetting the cmos cannot resolve the memory incompatibility and it's not strictly clear cut that the cpu is faulty and if it isn't the seller may come back at you. but as long as you send it back with a perfect Pga they may not necessarily protest but might wanna charge a handling fee just for the open box- makes it harder for them to resell new.
The memory being non compliant and 2 mismatched kits I am confused about but assumed you didn't build the system yourself and bought it pre made. Anyway best to leave the 2x4gb out and just run the 5900x with the 2x16 with xmp enabled.
You'd have to buy an altogether different memory kit preferably of another make eg. kingston or crucial while 3600mhz corsair vengeance looks pretty acceptable in userbm - for the varities that are qvl certified and compliant. To determine if memory compatibility is slightly off between the two cpus. These 3200mhz corsair vengeance are of the lower and slower variety unfortunately and non compliant possibly what's producing the memory hit or miss effect.
