Learn about RAM at 3000MHz in a MOBO without overclocking capabilities.
Hello, I've gathered a lot of information from online searches and noticed many differing opinions. I own two configurations of CMK16GX4M2B3000C15 version 5.32 (16GB with 2x8GB RAM, 3000MHz, 15-17-17-35 at 1.35V). My system includes an AMD Ryzen 9 5900X running at 4.2Hz (AMD OC from MOBO), an RTX 3080, and a 1200W seasonic PSU. My RAM operates at 3000MHz with DOCP boosted via the motherboard. However, I'm struggling to push performance beyond 3600MHz, as the motherboard claims it can handle up to 4600MHz (or similar specs). The manufacturer states that 3001+ is not recommended and suggests avoiding overclocking. Some reviews mention issues with Corsair for AMD builds, while others claim Intel-focused components aren't worth the effort. Based on what I've read, your current RAM listing—marked as supporting high-performance overclocking—might not be suitable for reaching those higher frequencies right now. Consider checking updated specifications or consulting more recent guides before proceeding.
It’s around 3000mhz ram, but the performance boost isn’t worth the hassle. You might want to try a different XMP profile and check if it works. Run Memtest86 for an hour or two to catch any issues. Alternatively, start testing your own timing values. Corsair LPDDR memory is notoriously cheap and often disappoints. Keep boosting in ASUS OC but don’t rely on it. A Cinebench test on the 5900X is a good idea before turning off OC entirely.
The simplest approach to begin with RAM overclocking on Ryzen is using the Ryzen Dram Calculator. It isn’t the top choice for pushing RAM speeds, but it helps you get started. Have you tried this method? There’s also a more practical hands-on way where you can actually boost your RAM performance and see bigger improvements than with the calculator, though it requires more time. https://github.com/integralfx/MemTestHel...guide/DDR4 OC Guide.md
I plan to check the GitHub after dinner here. But the video isn't useful since the RAM isn't supported in the DRAM calculator. Thanks for the info—just noted I have an "8Gb A-die" and the "A" die isn't available under DRAM Cal. I read that Corsair sometimes swaps memory ICs in their high-speed kits, sometimes 2-3 times, yet Burner still reads the original chip.
Yes, the motherboard can support an OC up to 4600, so you can use that model. It’s good to avoid Corsair with AMD chipsets for this reason.
I've explored the details thoroughly and your feedback has been clear. The MOBO guidelines for a 5900x platform claim higher RAM speeds than the system can actually handle, which seems like marketing. For quality RAM, I'm considering a 3600MHz TridentZ RGB or Ripjaws—just focusing on performance. I noticed using all four slots won't push it beyond 3200MHz, so I might stick with two sticks if I upgrade later.
It's true, the system struggles to maintain performance. I'm managing 4x32G dimms on my R5 3600 at 3600C18, though the secondary and tertiary timings aren't ideal. My PC uses 4x8G dimms at 3600C16 with similarly poor timing. I'd suggest considering 3200C14 kits that are reputed for Samsung B die compatibility. Anything else might not deliver good results.
