1000-series (Summit) and 2000-series (Pinnacle) were monolithic designs (everything is on a single die).
5700X is chiplet design (separate Core+Cache Die and an IOD, connected through a magical high-speed interface going through the package). So the slightly disappointing memory latency is probably not too surprising. But if you're comparing against others with the similar setups, I wonder if there are more tweaking you can do with the DRAM timings. I'd say you're still much better off, even disregarding the massive Zen1->Zen3 Core improvements, because you had 8MB L3 per 4-Cores before (4Core+8MB | 4Core+8MB), whereas you now have full 32MB L3 directly usable by all 8-Cores.

The only strange thing is memory latency in AIDA64 tests, thought it would be lower for my XMP 3200 16: from 77.6 ns it lowered only to 70.9 ns.

Thanks. It worked out. Haven't yet checked it in stability tests, but in games everything works fine. And FPS is like in 5700/5800x reviews. |

Looking through https://www.asrock.com/mb/AMD/AB350%20Pro4/#BIOS
If you're on pre 3.40, then you need to go to 3.40 (Bridge) first. Then 5.40 Then 7.00 (Bridge) Then I'd go straight to the latest beta (8.02). Then finally swap the CPU. The BIOS page says 7.40 and 8.02 support Vermeer, which 5700X is, but they never updated the CPU Support List. So AsRock's Support Page is contradicting itself. Never a good sign.... Most of their BIOS pages tell you they don't recommend newer BIOS if you're using older CPU, but I have a 2700 (Pinnacle) on B450M Pro4 2.0 running just fine on the latest beta BIOS (AGESA 1.2.0.8). However, I do not own any 1000-series (Summit), so I can't tell you for sure if you'd be safe to update BIOS, if 5700X ends up not working. This is important because you can't go back to older BIOS, according to the BIOS page. |

Is it possible to upgrade from Ryzen 1700 to Ryzen 5700x with this motherboard? If yes then what is the sequence of BIOS upgrades?
