Checking if a 4000MHz option works for this Ryzen 5 5600G setup. Also, looking into the latest Corsair RAM.
Hello everyone, I'm a beginner in custom PC building, so please keep in mind I might still have some gaps in my knowledge. I've been around for years with people who have assembled their own computers and I had some extra cash, so I decided to give it a try in the gaming and tech scene. It's been working well so far, but now I'm running into a problem. I hope someone can assist me – it's been a bit frustrating. Here’s what I have set up: 1. AMD Ryzen 5 5600G at 3.9GHz (6-core APU) 2. Gigabyte B550M AORUS PRO-P Micro ATX AM4 (motherboard) 3. Corsair Vengeance RGB Pro 32GB (4x8GB) DDR4-4000 CL19 (RAM) 4. Samsing 870 Evo 1TB SSD 5. Corsair 750x RMx 80+ Gold Certified power supply (for full PC configuration, click here) I chose the Ryzen 5600G with built-in graphics because of the high prices on GPUs right now. Back then, I considered upgrading to the 5700G since it seemed about a 4% performance boost. However, after some gaming sessions, I realized I wanted maximum frame rates. That's when I swapped my existing Corsair Vengeance 16GB RAM (2x8GB, 3600MHz CL18) for Corsair Vengeance RGB Pro 32GB (4x8GB, 4000MHz CL19). Now the issue started. I updated my motherboard's BIOS (F14e), confirmed it supports 4000MHz RAM, and checked that the Ryzen 5600G does. But in Task Manager, the RAM is only showing 2133MHz. I turned on XMP in BIOS settings, but nothing changed. When I tried to set the FLCK Frequency to 4000MHz, the system froze and displayed a "black screen of death." I had to power down the PC and reset CMOS by briefly touching the motherboard pins with a screwdriver – all settings were lost, but it worked once again. So, did I squander $250 on better RAM that won't work? Or am I missing something or making a mistake? Please let me know if you have any screenshots or want to discuss further. Your help would be greatly appreciated!
It doesn't seem to work at 4000 fclk. Most Ryzen APUs usually handle around 2100-2400 fclk. High-speed RAM is best, especially with a 4x8 configuration which can strain the IC if you're using four memory sticks instead of two. The chips should still be decent given the 4000 MHz speed, though they might not perform as well. Hyixin dies are still an option but at this frequency they’re unlikely to be reliable unless they’re high-end models.
It's possible your CPU isn't compatible with 4000MHz. Many systems will restart at lower JEDEC speeds if they can't boot at XMP. Try turning on XMP and reducing the clock speeds to around 3800MHz or 3600MHz. Ryzen processors typically handle memory speeds up to 3600MHz, though higher speeds like 4000MHz are challenging. Increasing the voltage slightly (from 1.35V to 1.4V or more) might help, but results aren't guaranteed. If you can return your RAM, do so. Getting four high-speed sticks is tough, and 3600MHz CL16 is usually optimal for most applications. Opting for 2x16GB if you need 32GB works well overall.
The FCLK rarely reaches 2000MHz on Ryzen systems. In reality, it matches the specifications for 4000MHz RAM—it’s not actually 4000MHz. DDR stands for double data rate, meaning two transfers per clock cycle. The RAM operates at 2000MHz with a speed of 4000 MT/s (megatransfers). Running at a 1:1 ratio with the FCLK means the actual frequency stays at 2000MHz, not 4000MHz. Most motherboards don’t support such high frequencies. If you hit that target, you’d need to reduce clock speeds or switch to asynchronous operation. Async can add up to a 25% performance loss, so unless your app handles it well, aiming for 4000MHz is unlikely to pay off. Instead, consider locking clocks at 3800MHz with a 1900MHz FCLK. This gives you more flexibility and lets you gradually increase the frequency if needed. Even without reaching full speeds, you can still improve timing margins.
I assume you activated the XMP profile, which is likely what you meant by DOCP. The XMP configuration should automatically use your RAM at its maximum capacity without further adjustments. It also appears that achieving a 4000MHz clock speed with your Ryzen processor is challenging, particularly with four 8GB RAM sticks.
Really thinking about your suggestion to send them back and get two Corsair 4000MHz 16GB drives is challenging for me. I just aim for the highest possible memory speeds, but I’m not confident enough to adjust the voltages myself. Ugh. I shared my CPU-Z screenshots in another reply above—check it out and let me know if it gives you any insight into my setup or what you mentioned.
I’d hesitate to use 40000MHz DIMMs, particularly with Ryzen processors. Ryzen generally thrives at 3600MHz with precise timing, and pushing beyond that isn’t just a step—it’s a notable accomplishment. The 3600MHz CL16 offers the optimal balance for Ryzen, delivering strong performance without much adjustment. If you aim for top-tier results, the 3600MHz CL14 provides better speed, though it comes at a higher cost and may need some fine-tuning to function properly.
For Corsair RAM, I’d steer clear of it outside the Dominator lineup. Most other brands often use memory ICs that aren’t well-suited for Ryzen’s demands. These chips tend to struggle with stability, especially when pushed above 2666MHz, making it difficult for Corsair LPX sticks to boot reliably.
