Inquiries on boosting RAM speed
Inquiries on boosting RAM speed
It makes only a small impact unless your GPU and CPU can fully utilize the added power. The guidance comes from an older discussion by @App4that: generally yes. Higher supported RAM speed improves CPU memory controller performance, increasing your odds of successful overclocks. As long as your motherboard allows memory overclocking and the BIOS permits desired speeds, it's essentially a matter of luck.
I'll give you a quick crash course. 1. It's better to have lower latency than higher frequency 2. It's better to buy higher tier memory with lower latency at the expense of frequency. 3. RAM overclocking will give you at most 7-8% improvement if your CPU can handle it and if RAM can handle it. Usually though, it's only about 3-5%. 4. DDR4 - look for 3200/3600 CL14. DDR5 - look for 6000 CL30. Samsung RAM chips are inferior and you should avoid them.. I think the better ones are from TSMC but I'm not sure. Higher latency memory is almost always from Samsung tho..
The material doesn't focus on one correct idea. Opt for higher frequency, aiming for the highest possible speed while adjusting timing as needed. Complexity rises with CPU features like gear modes, but latency stays similar. RAM performance is mainly measured by frequency, not timing precision. A 4000 CL17 setup usually performs better than a 3600 CL14, even if latency calculations suggest otherwise. It varies by CPU model. Improvements can range from 20% to single digits, depending on many factors. DDR4 Samsung diesels offer the tightest timing, while DDR5 SK Hynix leads in speed and precision. TSMC manufactures RAM, but SK Hynix currently holds the top position in both speed and timing. The motherboard must allow memory overclocking, and the CPU should support higher memory ratios.
I have a 5600x and an Asus ROG Strix B550-f gaming Mb. Previously, I could run RAM at 3700 MHz or 3800Mhz, but when I tried higher speeds the PC crashed and it didn’t run smoothly again. I’m unsure how to raise voltages or anything similar, possibly because of that. How can I boost voltage on a ROG BIOS? And what’s the safe voltage limit to stay under?
The key voltages for Ryzen 5000 memory overclocking are SOC and DRAM. Set the SOC to 1.15V, it's generally safe up to 1.2V, though most chips perform best between 1.1 and 1.2V. DRAM voltage varies by chip type—some tolerate up to 1.6V, others should stay below 1.35V. You can check your memory chips using tools like Thaiphoon Burner for most setups. If you use Corsair, G.Skill, Crucial or Kingston products, label reading helps identify the exact sticks. Other voltages like VDDG and the 1.8V rail matter too, but adjusting them often causes instability, so avoid changing them unless necessary. I don’t know the exact settings on my board, but they’re usually in the overclocking menu.
I was attempting to provide a clear, broadly applicable solution. Many here just say "it depends" and move on. I understand your point, but I needed some concrete guidance. Hardware Unboxed conducted memory scaling tests—anyone can review them and use HU’s insights for their requirements.
