Are the memory settings the same on both sets of RAM?
 
If you had any previous xmp/overclocks, have you tried clearing the CMOS to see if all four sticks would then be detected?

Did that work for ya?

Im having a very similar issue, I have the same mother board and am using the same ram, I previously had 16gb of 3200mhz and just purchased 16gb more of 3200mhz and corsair vengeance LPX, but when I installed the 2 new sticks I didnt even get a post screen.

My 5600X is a sweet little cpu, coming from a 5900X owner.

turn base. They don't usually have ultra high graphics, sometimes need multicores, like Civ VI but they do share is a need to calculates each game turn for each AI so the faster the individual core the less time each AI turn takes.

Thanks for the advice! I'm not sure if this changes anything but I forgot to mention I do play games in 2650x1440. I was lucky enough to get my hands on a  EVGA 3070 XC3 earlier this year and am so far loving it!

I dont think I got beyond 10 gbs while under pretty heavy load so capacity doesn't seem to be an issue. Thanks for your help!

2 sticks will be fine, as will 16Gb.
My system uses 12Gb as a rule, but I decided to get 4 sticks in the end, It makes for no gaps in the LED display and maybe 32Gb to allow room for program expansion demands of the future? 

if you don't need the capacity then faster RAM will be better, depending on the latency of your current kit. 3200 CL16 is a bit better than 3600 CL18 for example, but the actual in-use benefit for gaming is going to be negligible at best. There's also a whole thing about Ryzen 5000 benefiting from dual-rank DIMMS (or 4 single rank DIMMS), but upgrading specifically for that is likely not a good return on value.
Just marketing BS. Your motherboard should have a QVL for RAM that will give you the highest chance of success for XMP (DOCP for AMD), but that doesn't mean other quality kits won't work. My RAM was not on my motherboard's QVL, but works just fine at 3600 MHz. Regardless, DDR4 is DDR4 and is not made specifically for one CPU brand versus another.

I usually go here PassMark Software - CPU Benchmark Charts
but I suggest you also read

It was from those full reviews above I went for the 5800x because it had the faster single core that suited some of the games I play and it has the faster multicore so better for other games, and more cores means I can run a few more programs in the background. But the 5600x is good too if you don't need the extra %s

5600x will be perfect for you since as commented above the streaming will take advantage of NVENC.

I'd look around in forums and watch those performance comparison vids on YT

User benchmark is pretty unreliable, and I wouldn't recommend a CPU upgrade based on that site.
 
What games do you play most, and what do you do most on your system? The difference between the CPUs is two cores, so if two extra cores benefits you, it's worth considering.
 
But if you want generally good gaming performance for a decent price, the 5600X is usually far more suitable.

Don't trust userbenchmark, at all. I'd get the 5600X and spend the change somewhere else

If you're doing streaming/productivity stuff in addition to gaming, go for the 5800x.
 
If not, then the 5600x is the better value choice. I only game and the 5600x has been fantastic so far!

yeah the SSD runs under the max speed for pcie 3.0, so getting 4.0 would be pointless.
 
also no gpu benefits from pcie 4.0 yet.

I agree with @SavageNeo- Why introduce additional cost with a new mobo when your current one supports the latest gen AMD CPUs?

does not matter
 
you would not benefit with pcie 4 at all with those things.
 
Since you already have a b450 board, just update the bios and get ryzen 5 5600x or 5800x.
