Xmp Enabled isn't starting. What should I do to get the right settings?
Xmp Enabled isn't starting. What should I do to get the right settings?
Hi all, I recently assembled my new rig using these components:
Processor: i7 13700KF 3.40Ghz
Motherboard: ASUS 1700 TUF Z690-PLUS Gaming
Memory: Corsair DDR5 32GB 5600 Vengeance CL36 CMK32GX5M2B5600C36 2x16GB
Everything functions properly, so I accessed my BIOS to turn on Xmp, as the RAM was running at 3600. I tested both Xmp I and II, but the PC won't boot and halts during the check, displaying a warning light on the DRAM.
I then manually tried different frequencies, and the highest stable with Xmp enabled reached 4400mhz.
My concern is whether this is typical behavior and if I should gradually increase the voltage to boost frequency. I recall my previous setup had the Xmp profile enabled, which set the frequency to its maximum and worked fine.
I’m not seeking an instant fix, just aiming to grasp the process carefully; I’m open to trial and error, but caution is needed to prevent hardware damage.
Additional information provides further guidance on the topic.
Begin by adjusting timings, such as loosening them, to achieve higher frequency stability. If that doesn’t work, consider increasing voltage, but proceed carefully with small changes and verify stability.
Maximizing performance from your RAM often requires manual overclocking followed by testing. This process can be time-consuming, but the outcome might be exactly what you need.
It's possible though I'm not sure, but BIOS updates could bring more stability, so what version are you using? The most recent BIOS is Version 2103 2022/10/19. DDR5 is quite new and many compatibility and stability problems have been reported. As before, BIOS updates can be risky.
How long are you waiting on the dram led? There's often a certain amount of memory training that's happening as the memory controller adjusts voltages and settings in bios to accommodate the new raise in speeds. It can take a minute or 3 and even several reboots as the bios adjusts. DDR5 is ECC ram, and the voltage regulation is on the stick, no longer in the cpu, which can complicate things.
XMP is a generic setting. The ram itself is factory guaranteed to be able to hit that speed and be stable, but there's no guarantee that your particular cpu/motherboard will be happy with those settings, often requires manual adjustments to the memory controller or transmission voltages to get it to work.
I waited several loops where the pc restarted each time and then turned it off once the led got stuck on the Dram, stopping further loops. Perhaps I should give it a bit more time.
This may or may not assist. I encountered problems with the PC failing to boot using TUF Gaming Z690-Plus with WIFI D4 and 64 GB Corsair Vengeance LPX 3600Mhz C18. The issue was resolved after updating the Mobo firmware. It seems both the firmware and XMP Profile 2 might have been necessary. I updated the motherboard and profile, but it still didn't work on XMP 1. However, XMP 2 also failed before the motherboard update.
I confirmed my RAM was functioning correctly and benchmarks indicated stable performance, so I proceeded. lol
