Been awhile, and really enjoying playing with the Ryzen platform as of late. Working on a build for a relative, and decided on upgradability sake to go with a B550 board, and due to regional availability picked the asus tuf gaming for the mATX board. Saw another thread regarding using prior gen CPUs in this platform (3400G), and I've done the same.
Originally was going for a low end price point, so only got 8GB of ram at 3200Mhz. Worked great as XMP with the 2 4GB sticks - no issue.
Although I knew the vega 11 used the shared RAM, I forgot it literally carved it for itself. Realizing my error I bought another set of 2 4GB sticks, but this time XMP/DOCP caused stability issues at both 3200 and 3000. I was able to manually push the ram to 2800, but thereafter won't POST.
Asus TUF Gaming B550M Plus Wifi
AMD Ryzen 4 3400G (no OC planned)
KINGSTON 4GB / 3200MHZ DDR-4 HYPERX FURY BLACK Timing (CL): 16.0
What I also noticed is in Ryzen master, the ECD(CPU) seems to be pegged at 94% of the 95Amps, which I guess is a result of setting the 2800Mhz manually and leaving the rest to auto. Any recommendations and insight here is welcome.
So hoping someone can point me to some good memory OC tips to help bring my 4 x 4GB set back to 3200 or at least close given how dependent on the 3400G is on memory speed. My guess is some timing and DRAM voltage tweaks are in order, but not 100% sure with the new terminology, differences from Intel, and ECD.
My alternative is to abandon the lower price point and simply buy 2 8GB sticks, but that's no fun.
Learned that my sticks come with different manufacturing dates & manufacturer (all are P/N: KHX3200C16D4/4GX) if that makes a difference.
Slot 1: Micron Tech - 25 / 20
Slot 2: Micron Tech - 25 / 20
Slot 3: SK Hynix - 23 / 20
Slot 4: SK Hynix - 23 / 20
Ironically I was sold sticks in slots 2 & 4 together and then 1 & 3 as "kits".
Just noticed the DRAM Calculator tool & materials in the general AMD thread.
So will review those details and come back with any questions.
