Question Enabling XMP leads to a black screen?
Question Enabling XMP leads to a black screen?
The system is reporting specific latency values for different operations. It is showing delay times in cycles and bytes for various commands related to DRAM communication. The numbers indicate how long certain processes take, helping optimize performance.
Those figures might reach levels suitable for 6000 MHz. You could attempt to set the frequency at 6000 without turning on xmp. However, locating a suitable RAM timing setup can be challenging and demands considerable effort, so if you prefer not to tackle that, the only option might be to opt for a slower system.
Adjusted my RAM speed to 6000MHz and confirmed the system is operating at that frequency. Is there anything else I should do?
This indicates that the advertised RAM speed (8400 MHz - CL 40) won't work with your motherboard or CPU setup. As mentioned before, you can either attempt to push it to discover its limits on your system or return it and opt for a slower RAM model. Running it at 6000 MHz would be a waste of the money you spent on the 8400 MHz unit. If you're comfortable with that, just keep it as is.
Manual overclocking requires skill, especially without prior experience. You'll need to raise the frequency, fine-tune timing, and possibly adjust voltage (I recommend setting it to 1.4 V and leaving it unchanged) to achieve the best stable performance. It's not an easy process.
Some motherboards offer predefined overclock profiles in the BIOS settings, typically under AI Tweaker. If available, you can experiment with these options until you find a suitable one.
8400 MHz CL 40 is quite fast, and based on my perspective, only individuals well-versed in RAM specifications should consider purchasing such kits. You might be fortunate to get stable performance out of it, but it's not guaranteed.
When running your RAM at 6000MHz, you're asking about adjusting the voltage to 1.4V. This setting is likely intended to fine-tune the voltage for that specific frequency. The 1.4V value may relate to a different MHz or be part of another adjustment. Regarding NPU boost and AEMP 3, they are part of the AI overclock configurations.
AEMP 3 can help for stability at higher speed if you have 4 ram modules installed. What is your configuration exactly? I just read your original post again and do you really have 4 sticks of 24 GB each? If it's the case then no wonder why it's not working with XMP. 8400 MHz CL 40 with 4 sticks? I don't even think it's possible. You will actually have a hard time making it work stable at more than 6400 MHz.
Also, if you have four sticks, did you buy them in two different kits (as your original post suggests)? This is really not good and you should never mix kits together. The rule is that if you want four sticks buy a kit of four.
If you want to run at 6000 MHz and it's stable then leave the voltage as it is. But if you intend to increase the frequency then you should crank it up to 1.4v.
