Trouble enabling XMP
Trouble enabling XMP
Hello
Here’s a revised version of your text with the same length and structure:
My setup includes:
Mobo: ASUS Maximus XI Extreme
CPU: i9-9900k
GPU: RTX 2070
PSU: Corsair AX1600i
Cooling: Custom Waterloop
RAM: Corsair Vengeance DDR4 4x8GB 4000Mhz 19-23-23-45 1.35v -> Gskill Trident Z DDR4 4x8Gb
4000MHz 15-16-16-36 1.5v
Initially, I’m just starting out with overclocking. AI Suite managed the CPU adjustments, but while experimenting with settings, I noticed my RAM was clocked at 2133MHz instead of the expected 4000Mhz. After researching RAM specs and timing details, I dove into XMP configurations. It turned out XMP wasn’t enabled in my BIOS, so I fixed it by enabling it, saving changes, and restarting. After rebooting, the system booted normally but returned to default RAM speed.
I then tried manually tweaking voltage and timings in the BIOS, but adjustments didn’t yield results. Eventually, I ran a MemTest using Windows Memory Diagnostics. The test flagged a hardware issue, which persisted until about 3/4 of the process before it crashed. I ordered replacement RAM (Gskill Trident Z DDR4 4x8Gb 4000MHz 15-16-16-36 1.5v).
Today, the new RAM arrived and was installed correctly. I used Karhu RAM Test, which reported 500% coverage with no errors after a short run. When I powered down the PC, booted into BIOS, enabled XMP 2, and encountered a boot error with code 0x000000e. Resetting the BIOS back to defaults resolved the issue.
Currently, I’m running a longer test under the same settings—over 2 hours and 27 minutes of coverage with 2869% success rate and no errors.
I’m reaching out for expert advice since further self-study seems unlikely to help. Thank you for your support!
Hi RedLine,
I encountered a similar issue where my motherboard wasn’t interpreting the XMP profile properly. In your BIOS there should be an option to view XMP settings from your kit, which includes more than just the primary timings—often referred to as SPD or read SPD. You then choose the memory dimming level you wish to apply. If you can’t locate this feature, use Thaiphoon Burner to read the SPD of your RAM kit. There are two sets of numbers stored: one for standard JEDEC settings and another for XMP. Make sure you’re reading the XMP settings, which are listed under the higher frequency (around 2000mhz for DDR). Write them down. Reboot without XMP enabled. Now...
Hi RedLine,
I encountered a similar issue where my motherboard didn’t interpret the XMP profile properly. According to your BIOS, there should be an option to import XMP settings from your kit, which includes more than just the main timings—often referred to as SPD or read SPD. You would then choose the memory dimming level you wish to use. If you can’t locate this feature, consider using Thaiphoon Burner to read the SPD of your RAM.
There are two sets of numbers stored: one for standard JEDEC settings and another for XMP. Make sure you’re reading the XMP settings, which are typically listed under higher frequency settings around 2000mhz (though technically it’s 4000mhz due to DDR). Write these down. Restart without XMP enabled, then enable it and enter all values you find from reading the SPD.
As a tip, it’s usually fine, but verify your motherboard’s QVL compatibility list for memory kits. They might not support them in a 4-stick configuration, so you may need to adjust frequency or voltage until they boot.
Good luck, and hope this resolves the problem.
