Comparing 5600 MHz RAM and 6000 MHz RAM highlights differences in speed and performance.
Comparing 5600 MHz RAM and 6000 MHz RAM highlights differences in speed and performance.
I purchased the DDR5 5600 MHz but faced buyer regret after seeing the 6000 MHz option. Returning my 5600 MHz to get the 6000 would make sense, but is it a good move?
Also, in most games I've played, there's very little performance difference between even stock 4800 and 5800 (highest speed I can get with zero issues)... and even running my kit up to 6400 (which is its rated speed, but I have some issues with pc switching itself off and on at boot sometimes at this speed, even though it's 1000% stable once booted, I choose to avoid this annoyance), there's little to no difference in fps. So I'd just stick with your current kit to be honest. Depending on the kit you have, if it's hynix, you can also look at buildzoids fast easy timings for ddr5 video on YouTube. Using aida64 to judge the differences, I can see that my profile at 5800-36-36-36-28 actually performs basically on par with the default xmp profile 6400-32-39-39-102 in terms of write read and copy speeds and latency. (Obviously, applying the same sub timings at 6400 sees even further improvement, but I just can't be bothered with the hassle of sometimes having to wait for it to switch itself off and on again and sometimes having to manually do that if it gets stuck.... it always eventually boots and when it does, it hasn't reset anything, it's all running at the speed and timings set, and is 1000% hci stable, 10000% kahru stable. As someone who's been in your position and ended up spending on an expensive kit, I can say that you're almost certainly better off just seeing what you can achieve with your current kit, without raising temps, and staying stable.
The Asus model you mentioned is likely the AIO series, such as the AIO 15 or AIO 13.
Yes, the settings perform well on my M.2 motherboard with a Hynix kit as well. For other boards, especially ASUS ones, avoid adjusting the voltages in the video settings. On my setup, I used the MSI Try It profile (5800-36-36-36-77), booted it once, then updated the BIOS and changed the subtimings from the video. The results were approximately 93k read, 91k write, 88k copy with 64-69ns latency. At stock speed of 4800 MHz, I got around 75k read, 70k write, 65k copy and about 90ns latency. If I switch to safe mode, the numbers improve slightly. However, these changes didn’t noticeably boost FPS during gaming, so it doesn’t seem useful for my needs. It might help if you run many data-heavy tasks, but for gaming the difference isn’t clear.
It's not uncommon to experience boot issues; they can vary based on individual hardware and software conditions.
Experiences with boot issues differ based on the motherboard, RAM, and CPU IMC. A stable 6000 seems reachable for most users, though a slight SOC voltage increase might be needed. Going beyond 6000 is mostly dependent on chance and can lead to stability problems.
This also works for a RAM stick that supports 7600mhz by default? I'm stuck between getting DDR5 6400 or DDR5 7600.
Certainly. Here’s a rephrased version of your text:
It's common to see systems run smoothly at speeds well over 6000, particularly with certain Hynix configurations. However, stability is influenced by multiple components like the CPU, motherboard, and power supply unit. Generally, any change in these parts can impact overall performance to some extent. In my experience, I suspect the memory controller on my 12700K might have been the culprit. Above 5800, I often encounter problems. Earlier BIOS versions would sometimes trigger errors such as "memory overclock failed," requiring a BIOS reset to revert RAM speeds back to 4800. Now, newer BIOS versions eliminate these warnings and allow a smoother boot into Windows at 6400 with the original timings. The only recurring issue seems to be occasional crashes during reboots or startup from cold, where the system briefly powers off before resuming. In other cases, it hangs completely, with all components active but no display output. Manually pressing the power button twice to restart resolves the problem, and everything functions normally afterward. This pattern occurs across speeds starting from 6000. The absence of error messages might suggest a hardware limitation, possibly related to the motherboard rather than the CPU itself. Still, I believe the instability is likely tied to the memory controller nearing its limits above 6000, and the updated BIOS handles it differently by shutting down instead of reporting an error. Running stress tests confirms stability at 6400, though game performance remains unchanged. I’m leaning toward keeping the system at 5800 or maintaining a stable 4800 with JEDEC settings for better consistency.
