Basic questions about RAM, how many sticks you can use, and speed in MHz.
Basic questions about RAM, how many sticks you can use, and speed in MHz.
gpu and ram are unrelated; what matters is ram and a key point is that DDR3 runs at half its rated speed if xmp is enabled (for example, 3200 MHz becomes 1600 MHz). For optimal performance with Ryzen, you should pair infinity fabric with half the ram speed (so 1600 MHz for 3200 MHz ram).
Typically four sticks enhance performance since they're dual-ranked. OC might be a bit lower, but benches are better. Zen 3 offers plenty of IMC and mobos that can handle 4x8 at 3600 if you choose the right ones.
What a question! 😄 You're looking for someone you can rely on, right? Let me help you think about it.
It seems the setup relies on dual-rank chips to achieve dual-rank performance, while single-rank units can't do it alone. Some experts even argue that using two dual-rank sticks is more efficient than four single-rank ones, as it reduces stress on the memory controller.
You can usually find this information in the product specifications or by checking the packaging label. If not listed, contact the manufacturer or retailer for details.
xmp configures the timing and speed settings for the memory profile. If these align with the infinity fabric, it works; otherwise, it fails. (Feel free to adjust the details as needed.)
