I recently upgraded to a Ryzen 3700x, running the CPU stock with the stock cooler using bios v5.90 . Thermals are fine under stress test.
I also upgraded my RAM a few days later, looking to increase the meager bandwidth with the old 2133mhz memory. I purchased a 2x8GB PC3200 kit from Corsair listed on the compatibility list [CMK16GX4M2B3200C16] : https://www.asrock.com/mb/AMD/AB350M Pro4/index.asp#MemoryPR
Initially with the v5.90 bios I had instability issues under memory stress test (using AIDA64), using the XMP profile settings are 1.35v 16-18-18-36-54 1T. It would lock up the computer of blue screen after 2-5 minutes. Before spending any time troubleshooting I upgraded to the latest v6.60 bios, wwith the same XMP profile loaded reporting 1.35v 16-18-36-75 1T [note the higher tRC from 54 to 75 with the same XMP profile(?)]. With the latest bios zero issues with any stress test, cpu and memory are fine after hours of testing.
Here's my inquiry -- with the 5.90 bios I was getting 73ns latency in AIDA64 with the PC3200 RAM, but with the latest stable 6.60 bios latency is up to 88-89ns. This is better than the original PC2133 memory which are in the low 100ns range, but upper 80s latency seems high based on what I've found online. I manually changed the tRC from 75 to 54, and ran the latency check with no improvement so put the DRAM tRC back to auto. The AIDA64 memory bandwidth tests have been consistent with the PC3200, about 43000 read and 23000 write. I ran passmark and score in the 75th percentile in the memory benchmark, up from 40th percentile with the PC2133. There's definitely an improvement!
I posted this in AMD motherboards, as I suspect it's more a motherboard inquiry/tweak than what my RAM seems to be capable of.
I produce music on this computer, so I'm just trying to ensure the lowest latency possible for when I'm stacking virtual plugins and instruments in realtime.
