Help you adjust RAM timings
Help you adjust RAM timings
Trying to operate RAM at its rated speed but encountering issues. Seeking guidance on timing and voltage settings.
Using the X.M.P profiles you referenced, did you attempt to manually set the voltage between 1.4 and 1.45v in BIOS? Are you capable of handling DDR4-3200MHz/DDR4-3200MT/s? If so, it might be that your integrated memory controller or the motherboard's BIOS isn't supporting that configuration.
BOIS Version 1801 2023/01/04
This is the only Asus z590 ATX board that hasn't received a BIOS update in over two and a half years. I reached out to Asus, but the response was slow. I wasn’t sure if it was safe to increase the voltage beyond 1.35v.
Edit:
I recently attempted to raise the voltage step by step up to 1.38v for XMP1 3600. Each time, after about 20 seconds of memtest, the system would freeze.
I configured the BIOS to "Manual" mode at 3200 with a voltage of 1.375v, and it has held up so far—no crashes or freezes detected. It seems this setting might be the optimal configuration for this board, as it doesn’t require the four cycles of updates other Z590 models do:
Version 2302 2025/01/03:
- Added Minimum CRB patch for Intel IPU 2024.3.
- Updated ME to 15.0.50.2633.
- Enhanced system stability.
Version 2203 2024/04/17:
- Further improved system stability.
Version 2001 2023/12/20:
- Boosted system performance.
- Fixed an Intel security issue.
Version 1903 2023/09/07:
- Suggested for a critical update to address potential security risks.
- Improved system stability.
It seems you're adjusting RAM timings rather than reducing them. If CL=19 works but CL=18, 17 or 16 cause issues, then tighter settings generally mean fewer cycles per operation. Irrespective of the explanation, the i7-11700K supports up to DDR4-3200. Exceeding that speed depends on the specific RAM model, module compatibility, and your ability to fine-tune parameters.
Getting an older AMD 2600X to run at 3000MT/s failed because its maximum supported speed was DDR4-2933. Reducing timings from CL=16 to CL=18 made it stable during testing.
For aiming for 3600MT/s, consider raising the CL value by one or two cycles, giving memory more time to stabilize. Try tCL=20 at a higher clock rate of 1800MHz with DDR4-3600.
I apologize for my lack of understanding. I've read about adjusting memory timings but this is my very first attempt! It's a bit confusing, but I'm just trying to learn.
I was attempting DDR4-3600 at the manufacturer or motherboard timings, only as a starting point. When those didn't work, I came here seeking advice on adjusting them. I never tried CL17 or CL16 at that speed. After
@Lutfij
your suggestion, I then tried DDR-3200 with 16-20-20-38, which seems to be functioning well.
It appears you're suggesting I can just change the CL value to 20 without modifying anything else. This is precisely the kind of guidance I'm looking for, thank you! This is entirely new to me—I was assuming I needed to adjust other timing parameters to match something.

- Thanks, I'll pay attention to the voltage.
