I'd bump the RAM voltage in 0.01v increments up to maybe 1.3v to see if you can get it to settle. It may be that just a little more voltage will make it run. If that fails, I'd return the RAM as not performing to spec.

You have done your part. There are just a couple more things to try. Swap the RAM sticks in each other's slots. Return the RAM.

Or you can try their 2400 profile with SoC volt bump and RAM volt bump.]]> Mon, 25 Feb 2019 01:32:12 +0000 https://forum.asrock.com/forum_posts.asp?TID=10955&PID=60937&title=b450m-pro4-poor-stability-with-ram-at-2400mhz#60937 https://forum.asrock.com/forum_posts.asp?TID=10955&PID=60913&title=b450m-pro4-poor-stability-with-ram-at-2400mhz#60913 Author: phil25

I recently put together a new system with a Ryzen 2200G, B450M Pro4, and 2x8GB of G.Skill 2400MHz memory, and I am stumped by mysterious instability it seems to have when running the memory at the rated speed.

The memory is on the Raven Ridge QVL for the board (module name F4-2400C15D-16GFX) with a supported speed of 2400MHz. However, when I try to use both memory sticks (and only when using both sticks) at 2400MHz the system blue screens randomly after a few minutes of operation. I was hoping someone might be able to suggest a way to solve this mystery.

I've tried to test as thoroughly as I can, and have observed the following:

- When left to automatic settings, each memory stick is always detected as 2400MHz and given timing numbers that match those on the package (CL15-15-15-39 1.20V).

- When running in single-channel mode with one stick in the A2 slot at 2400MHz, the system is stable. This is also true when running with one stick in the B2 slot.

- Memtesting each of the memory sticks separately in each of the A2 and B2 slots (so 4 testing scenarios total), no errors occur after 8 full passes.

- It's only when running in dual-channel mode, with memory in both the A2 and B2 slots at 2400MHz, that the system blue screens with a random error code after a few minutes of operation. With UEFI version 1.60 (the version the board shipped with), this would generally occur after about 10-15 minutes.

- Updating the UEFI to version 2.00 caused the random blue screens to increase in frequency from every 10-15 minutes to every 1-3 minutes.

- If the memory speed is manually turned down to 2133MHz, then the system seems to be stable in dual-channel mode.

Everything else with the system seems to be solid, the temperatures look fine, etc. Have I misread the memory QVL somehow? What could be going on?
