Being a Ryzen 7 4750 I guess the scenario is that of a laptop. In that case, having never owned one with a Ryzen, I can't give you any suggestions. However, 65 ° C on the die is a more than the acceptable temperature for a fully loaded Ryzen 7. You have to see if it is a problem with your unit, or if other models of the same series are running all at that speed. In the first case, of course, your hardware has problems. Otherwise, in the latter case, it's a badly born laptop model built with components that are not harmonized with each other. Speaking of desktop PCs instead, I noticed that chipsets make a difference. For example, the X570 with a Ryzen 5000 has no problem pushing RAM to the max with the most extreme configurations while remaining stable all the time. Other chipsets, X470 and B550, on the other hand, are more sensitive to the type of RAM installed and in some cases, I had to lower the RAM clock a little. Personally, I prefer to mount MSI brand motherboards, the PRO or MAX series, but I also found the GigaBytes stable. However, lately, my experience is limited to AM4 Moterbords as I never mounted an Intel machine again after the first Ryzen 1000 has appeared.

The profile is set to standard stuff. It was already selected in the bios when I bought the thing. I haven't changed anything there other than the one time I set CM5 Aggressive? or something and it caused a reboot as soon as it went under load, so I changed it back.
I have all stock cooling and the CPU itself is OC resistant anyway so I haven't really fiddled with overclocking anything.

Seems like a good hardware configuration at a first look. What profile did you select in the BIOS for the RAM? I see your memory has a 3200 MHz XMP profile available. Did you select that profile in the BIOS?

Ryzen is spec'd to 95C. However standard practice for silicon is 65C if you want it to last. The lifetime vs heat is not a linear curve, you can kill a chip very quickly as you approach 125C.

I think it probably should run a little hotter under heavy load. My CPU isn't giving me performance numbers I expect of a Ryzen 4750G. The numbers aren't awful - they're within the ballpark(ish), but it's kind of like one of the cylinders isn't firing sometimes.
So when I look at the cooling numbers (running cooler than normal) and combine that with the performance numbers (running slower than normal) it leads me to believe my chip is being underutilized by my mobo and/or bios.

If you're running Windows 11, there a a lot of driver issues that the chip manufacturers are working through yet. Also remember that you might be comparing your cpu to people that have tweaked theirs to maximize its performance, including not running the TPM module which has been shown to lower performance quite a bit.

All modern desktop grade CPUs have been running at those temperatures for a long time now. Intel included. Big SIs like Dell or HP only use the bare minimum needed cooling so this is also something to keep in mind.
65 C is a fantastic temp under load. My R5 3600XT hits 75 C under Prime95 stress test with a CoolerMaster EVO-212 black edition on it. If you are dissatisfied with your heat levels, you would need to invest in either a very high end air cooler like something from Noctua, Scythe or BeQuiet; or you would need to go water cooling with an AIO. All of this assumes you can even fit the coolers into your system. I custom build all my PCs so I know I can put in whatever cooler I might need to go to in the future.
As for voltages, the funny thing with Ryzen is that they actually do better with less voltage in many cases. I ran a full per CCX/core tune on my system and found that performance went up, some voltages were set lower and overall heat didn't change any that mattered.

I'd be thrilled with the temp if I wasn't also lagging in CPU performance compared to other setups with the same CPU. I suspect something with my mobo/bios configuration.

I'm already running 2x16.
Anyway, I've got a bigger issue now, and I'll probably need a whole new case and cooling system.

.. with working on my own home project for many years in a stop and go fashion.
Every time I stumbled on something I don't like, I improve it!
Even though it's my own code, 6 months later, there is always plenty of thing that need improvement it turns out.
And the end result grow increasingly functional yet simple at the same time. Loving the look of it!

now I see many good deals for monitors, especially curved monitors.
but I am not sure what kind of benefit of using curved monitor instead of flat monitors.

I just bought a new monitor, and was considering a curved one. I think a curved monitor would be great for watching video and playing games.
I do the user interfaces for our products, so I spend a lot of time judging control layouts. Like everyone else here at CP, I also spend a lot of time looking at code. I think a curved monitor would be distracting in both cases, at least for me.
I bought a flat monitor.

I feel the same way. 
All the devs at my organization use multiple flat screen monitors at work and at home. I'm eager to know how devs find working with a curved screen. Because I have limited desk space at home (and am therefore forced to use a single monitor), I'm contemplating replacing my 1920x1200 screen with an ultra-wide panel.

I no longer use multiple monitors. Instead I use one 4k 55" and just tile my windows using Win+Arrow
It's way more flexible and clean, IMO, and less cable mess.
I'll never go back.

I only use a single monitor nowadays, at least at home. I lost my right eye in a fall last year, and a second monitor doesn't buy me anything now, as I have to move too much to see anything on it.
I keep a 2nd monitor at work, but that's only because it's the same touch screen monitor we use in our products. I occasionally need to check layouts on the same precise resolution as the product.

I have two curved monitors and my brain adjusted to the point where they now look flat and the flat screen on the adjacent laptop looks bowed out. In the end, I think they are more hype than anything else.
