Y? The spec says 1.35v @ 3000Mhz should work from the box, but it’s having trouble accepting that voltage, memory settings, and timing. This assumes all parts are functioning correctly.
It's also the IMC that needs the higher voltage. It's set to 1.35V at 3000 when using two sticks, not four.
Running four sticks presents greater difficulty than two. As a check, if you use just two sticks, does it function at faster speeds? When using four sticks, you may need to slow down slightly. Also, ensure your mobile's BIOS is current. Compatibility with the motherboard often gets better over time.
Bios updated recently; I adjusted the DRAM voltage to 1.4 but it didn’t work. Should I set the SOC to a different voltage, or test with two sticks?
DRAM voltage is directly fed to your RAM and will only need to be increased if you increase the speed of your memory or tighten its timings. It doesn't matter how many stick you have. DRAM voltage is the operating voltage of the memory itself nothing more. If the kits sold can do 1.35v @3000Mhz out of the box then there no reason to increase DRAM voltage. SOC voltage which the IMC on and the IMC speed is based of DRAM speed so with 3000Mhz the IMC will be clocked at 1500Mhz. Which is higher than a R5 2600 native memory controller supports. I would set VDDCR SOC Voltage to 1.2v, also set VTTDDR Voltage to 0.7v
SOC 1.2 works reliably around the clock. I’d limit it to 1.25v when air cooling is active and 1.3v in water. The VTTDDR current helps manage bus impedance for fast performance while keeping signal quality. It’s typically adjusted to half the DRAM voltage, but for stable RAM speeds you can push it higher than the default.
I understand your concern, but reaching 3000MHz RAM won't necessarily improve performance significantly.
It really matters. Ryzen prefers quicker RAM. You might want to experiment with the Dram calculator for a smoother experience. The tutorial in the video explains how to use it effectively.
