Check DDR5 memory clock stability using CPU-Z
Check DDR5 memory clock stability using CPU-Z
Hey! Your setup looks solid with that G.Skill Trident Z5 and Ryzen 7 7700X. I understand you were considering a 6000 kit for better performance, but the one you got was more affordable than a 6000 CL30. You adjusted it to run at 6000MHz and haven’t faced any crashes. Now you’re dealing with a discrepancy between BIOS and Windows Task Manager readings, and CPU-Z showing a different clock speed. It’s not about half-speed here—it’s about the memory clock being lower than expected, fluctuating around 20MHz instead of staying steady at 3000MHz. You suspect a missing dynamic setting in the BIOS, which is common since CPUs handle it internally but you can’t always find exact fixes online. If you want your RAM to hit the full 6000MHz you set, try checking the BIOS for any memory clock adjustments or updating it to the latest version. Let me know if you need help with that!
If the difference between 6000 at 30 and 6400 at 32 is just 1-2%, don’t stress and aim for a higher CL value. You’ve likely already checked that. It doesn’t make sense to spend time tuning RAM when only a few percentage points matter. Instead, focus on adjusting the CPU. With some custom settings, you can push these Ryzen chips to very high frequencies during light work—adjusting Tmax offsets and more. JayzTwoCents has a great video showing how he boosted performance by fine-tuning voltage and temperature. Give it a look; your core voltage is quite high.
I understand this well. I've already turned on PBO, set the Curve Optimizer to 20, and the performance is excellent. As mentioned before, the first screenshot showed memory timings of 30-36-36-80, which I'm also pleased with. My concern is that the RAM I configured at 6000 should actually operate at 6000 without fluctuating around ~5700MHz. The core voltage looks high in that image since a game was running in the background.
I discovered something. It seems the MB has two BCLKs—one general and another for "cores." I already configured the cores to 100.0 in the BIOS, but it didn’t mention a setting for cores specifically. Now I’m trying to locate the BIOS option for the general one. Edit: I can’t find it either; even the search function only returns the one already set to 100.0.
