LEDs not functioning in unison during startup.
LEDs not functioning in unison during startup.
Purchased two 16 GB kits to boost my RAM, but I've observed that the second RAM module from the left is running a marginally slower LED sequence compared to the others. Is this a red flag or a sign of a defective RAM unit?
It's mainly due to how RGB is handled in RAM. DDR4 wasn't built with RGB in mind, which means most of its control logic lives inside the memory modules themselves. This causes a problem because the modules can't coordinate their timing, leading to eventual mismatches.
Are you certain this method functions correctly? I once believed synchronization happens via the motherboard, but I definitely experienced desync issues—especially with RAM sticks using openRGB. After installing a new motherboard, I tried Gskill RGB again. For several hours it stayed in sync (lol!). *20221102_201306.mp4* doesn’t guarantee recognition on the next boot, possibly due to an MSI issue, but at least it didn’t desync during my testing. I’d love to understand how this actually works—it might rely on a timer from the motherboard or CPU. In theory, it should be straightforward, since the RAM itself isn’t faulty; the sync control likely comes from hardware. That one stick seems different—maybe reach out to the manufacturer? Usually, two kits work fine, but if you’re unsure, that could help.
Observing each step more closely reveals a minor timing issue. That’s unusual, I wasn’t expecting the motherboard to influence this. I’m sure the DIMMs handle their own settings—especially on DDR4—and possibly adjust the animation speed using data from the command address bus rather than solely relying on the DIMMs as I once believed. It’s been a while since I explored this topic, so some details might be fading from memory.
It seems to be a similar situation, though the issue remains consistent. I’m not sure if the delay was intentional or not, but it just continues without problems. Good observation! Logically, the components should talk to each other in some way, and the motherboard likely has timers for this purpose—possibly MSI mobos are involved. My idea is that MSI might do this on purpose so users install their software (maybe not the best choice), but it probably relies on RAM timing. It could be using clock cycles from the motherboard, though that seems complicated. I think the sticks communicate via software, which explains why it worked with this specific board and failed with open RGB. It’s definitely a complex topic...
I powered on my PC and it loaded the settings instantly, amazing! The file 20221103_151054.mp4 works even better than before—definitely some kind of synchronization happening. Probably because this version never failed on my old B350M, so it’s safe to say it does now...? 😊 Edit: I’m curious if anyone else noticed this. The Trident RGB software uses about 0.1% CPU with minimal power, but when set to music sync it jumps to 2.4% CPU and medium usage—suggesting the CPU is managing everything smoothly.
