Windows startup delay during DDR5 RAM overclocking on AM5 platform
Windows startup delay during DDR5 RAM overclocking on AM5 platform
Hi!
I just changed my PC to an AM5 model:
Ryzen 5 7600 X
Asus Tuf Gaming B650-plus
MSI MSG A850G PCI Express 5.0
RTX 4090 FE graphics card
Samsung 970 EVO M.2
32 Gb RAM DDR5
At first, I tried the RAM I just got: Kingston FURY Beast DDR5 32GB (2x16GB) 5200MT/s DDR5 CL36. Setting the speed to 5200 MHz with AMD EXPO profile took about 21 seconds for boot. After changing it to 5600 MHz, stability improved but the boot time rose to 35-37 seconds. I wondered if I was making a mistake with the overclock.
Now I have this RAM: Kingston FURY Beast DDR5 32GB (2x16GB) 600MT/s DDR5 CL36. With AMD EXPO, I can reach 6000 MHz and the system stays stable during tests and gaming, though boot times remain high (35-37 seconds). Lowering the frequency to 5600 MHz with AMD EXPO also gives similar results.
Someone might explain why higher RAM speeds slow down booting?
I attached two screenshots from CPU-Z for reference.
Thanks!!!
Cheers!
Open task manager and examine the startup section.
You'll usually find a value labeled bios time at the top, indicating the duration before the operating system starts.
This figure comes from your motherboard's BIOS but its exact meaning isn't clear to me.
It might be worth testing other configurations; it could indicate additional memory checks by the BIOS.
In the end, does boot speed really matter?
Ryzen pays close attention to RAM configurations. If the system's BIOS doesn't accept the chosen settings, it attempts to adjust to a compatible option. This process requires some time. You can check CPU-Z to view the current RAM settings. Additionally, consider using sleep mode instead of hibernation—this puts the PC and monitor into a minimal power state, effectively shutting them down. Sleep/wake transitions happen quickly, just a few seconds.
You're welcome! I verified that value, which is 28 seconds.
It looks like the BIOS logo takes a long time to appear, possibly indicating a need for further investigation.
Thanks! I just uploaded two images from CPU-Z. I'm not sure if they'll be useful, haha.
I discovered a fix!!! I changed the BIOS to version 28/08/2023 and then set "Memory Context Restore" to "enable". Now, starting from power on, it takes only 23 seconds to reach Windows. That's a great improvement from nearly a minute to under 30 seconds 🥳🥳
