RAM: Corsair Vengeance 64GB DDR5-6200

Is this a 2x32GB kit or 4x16GB? Also 6200MT/s will have some issues, mainly that it will default to 2:1 mode and have terrible performance. Either go into BIOS and set UCLK DIV1 Mode to UCLK == MEMCLK (this I'd want to run a stress test to confirm stability) or drop the speed to 6000MT/s.

 

Anyway, as for the issue on hand, it's AM5 memory training. It takes a while, especially with 64GB of RAM. There are ways to reduce it by using Memory Context Restore, so try going into the BIOS and enable that setting (ASUS has that default to off), though just know that on some BIOS revisions (especially early ones) that can cause the system to not reboot properly (it's fixed on newer ones though, you might just need a BIOS update if you run into it).

My PC has always taken it's sweet time to boot up and I never knew why. I've disabled all startup programs, enabled fast boot, disabled SMART checks on boot, etc. Yet I still have boot times of 90-100 seconds and I've finally gotten so sick of it. I'm hoping someone here can help shed some light on what I might be doing wrong.

 

Here are my PC specs:

  • Motherboard: Asus Prime X670E-Pro Wi-fi (Non-CSM)
  • CPU: Ryzen 9 7950X
  • GPU: XFX MERC 310 Speedster RX 7900 XTX
  • RAM: Corsair Vengeance 64GB DDR5-6200
  • Boot Drive: Samsung 970 EVO 1TB
  • Storage Drives: WD Blue 2TB Mobile HDD, 2x Samsung 500GB SSD, 2x WD Black SN850X 1TB, and SK Hynix Gold 500GB M.2

One thing I have noticed is that during boot is that my motherboard status LEDs linger on the DRAM led the longest.

 

It would be greatly appreciated if anyone could help me at least get down to normal BIOS times or know if I can't.

It's a 2x32GB kit. I was actually using DOCP 1 for the memory settings in BIOS which had the frequency set to 6400MT/s. So I set it manually to 6200MT/s, set the UCLK DIV1 Mode to UCLK == MEMCLK, and enabling Memory Context Restore. I ran stress tests after I booted in and everything seems stable to me. Now my new BIOS time is 29 seconds.

Thank you so much! This helped me out a great deal.
