Random black screen indicating new RAM installation.
Random black screen indicating new RAM installation.
this ram is a complete set, assembled together in one package. or is it a combination of different types?
was this a fresh build or did you upgrade after adding more memory?
could you share more details about the process so we can understand the issue better and find a solution?
Yes, the RAM is a matched set and this appears to be a fresh build except for the CPU and GPU, which I obtained from my previous setup. It's functioning well with two sticks, but using four causes resets or results in a black screen. Thank you very much for taking the time to assist me—I really value your help. 😀
All four sticks functioned on a different motherboard. They should originate from the same batch. This isn't two separate sets, but rather four in one. I'm assuming the RAM is a kit of four and verified its compatibility with the new motherboard. Does that align with your understanding?
so it functions with two but not four. that's a beginning nonetheless. ryzen is famous for ram problems.
the usual way to attempt fixing them is to gradually increase the sticks at stock speed. if two work, try adding a third and check if it boots and stays stable. then add the fourth only if the third succeeds. i don't understand why but this seems to assist the system in detecting and setting up multiple sticks.
fill A1 and B1 slots, then insert a third into A2, and finally place the fourth in B2, hoping they'll all be recognized.
if all four function, you can attempt XMP profiles only after everything is stable. you might need to manually boost the speed and see the limits. four sticks will never match the performance of two, so it may not reach full advertised speed.
Interesting points to note is that the Gigabyte B550M-K manual page 10 suggests using A2/B2 for just two DIMMs. I recall some reports indicating that certain motherboards may not always correctly identify RAM in A1/B1 slots, though I might be misunderstanding.

What caught my attention is that Gigabyte offers four distinct Memory Support Lists tailored for AMD Renoir APU, Cezanne APU, Matisse CPU, and Vermeer CPU. It could be useful to verify whether your RAM package matches the relevant Gigabyte QVL. Kits with four compatible DIMMs are uncommon outside server environments where you might have a quad-channel Xeon or an 8-channel CPU setup. I rarely encounter such configurations on the web.
I own an older AMD system where I had to raise the RAM voltage by 0.05V (50mV) above the standard to ensure stability with four DIMMs. It's typical for systems to become less stable when using four sticks instead of two, mainly because of increased load on the CPU's integrated memory controller.
If your RAM operates at the JEDEC default speed—potentially around 2,133MT/s for your model—the BIOS likely sets the voltage to 1.20V. When you enable overclocking features like XMP/EXPO/DOCP, the BIOS usually boosts the voltage to 1.35V. It would be wise to confirm the specifications of your RAM to ensure accuracy.
I recommend manually adjusting the RAM voltage to 1.250V (up from 1.200V) at 2,133MT/s and testing stability. Most DDR4 modules function well at 1.35V, so you might also try 1.300V or 1.350V under similar conditions. Smaller adjustments in 10 or 20mV steps could be more effective than larger jumps like 50mV.
CAUTION: Be careful when changing RAM voltage manually. A 500mV increase (instead of 50mV) might cause damage.
If your system remains stable at 1.250V with 2,133MT/s, consider using MemTest86 and installing a USB memory stick. Boot from MemTest86 and run a full test session (several hours). Any errors encountered would indicate potentially unstable RAM.

Preferably, choose a RAM package with EXPO timings optimized for AMD platforms rather than XMP timings intended for Intel CPUs. The distinction between XMP and EXPO settings can be subtle yet significant.
a nice touch. i didn't think about whether the voltage needed tweaking. after doing it countless times, it's hard to remember what you're actually doing.
