Eh to me it was underwhelming so much that I gave it to my friend and went back to a 1600AF until 5000 arrived. That 1600AF could also do 4400MHz.

R5 3600 vs R5 1600AF is not equal in performance at the same speed because of IPC uplift (~13%).

In fact a 4.2GHz 3600 would be equal to a 4.7GHz 1600AF

1600 vs 3600 are miles apart in performance. 4.4 is very good. Don't forget that this CPU has 3600 baseline. It was designed for that frequency at 1.1 v.
4.4 ghz is way much then 3.6...

My Gigabyte even when I have XMP on (1.35V) set DRAM voltage to 1.365V.

Reminds me of the DDR1 days, where my Asus A7N8X-X sets the DDR1 SDRAM voltage to 2.6V. Seemed that in the late DDR1 days, 2.6V became a defacto standard, at least for the DIY motherboard market!
But, it did say 2.6 in the BIOS, IIRC.

That wasn't the point. I collect hardware cups, meaning more percentage headroom is always better. Also my friend needed a workstation ASAP and I started getting my Ryzen 5000s to test soon after. Surprise, the 5500 is the best overclocker of the whole stack.

I also have lots of hardware stacked up over the years. Mostly after I've done repairs for others meaning, most of it is unusable,
but I do have several CPUs in working order.
It doesn't surprise me 5500 is the best overclocker.
Lower stacked CPUs often are.
I had Athlon XP 2100+ from way back in the day,
also could get to 2 ghz easily.
For that time, that was real good.
I have to learn more about Ryzens. It seems best way to improve performance on AM4 platform is to overclock the RAM, infinity fabric and tighten latencies.

If you can find working boards (the hardest part) for those old CPUs, you should join HWBOT and bench them. Techpowerup.com has a team. I was originally on the overclock.net team but since migrated to the extremehw.net team. It's a lot of fun if you are hardware tweaking enthusiast.

Yeah mine does too... I can see on the right of screen the DRAM actual voltage and its the same as in windows

My old PC with Athlon XP 2100+ still works. I just gave a PSU and an old Nvidia 4200Ti to a friend a loooooong time ago.
I'm not sure if I'd remember voltages I used on that overclock. It was so long ago, I was just 10, 11 years old then.
That's when my love for PC building and hardware began, now I'm a student, last year, IT.
I can find a PSU easily, but an old AGP card? Hmmm Might be a hard thing to do.
But somehow, I'll get it to boot again :)
