I read that many of those Ryzen X670 boards take several minutes each time after a cold boot? its not that bad. not lightning but its not multiple minutes. I have an 4.0 m2 ssd so its pretty fast. 7900x3d , 64gb 6200mhz 30CL Ram, RTX 3080

I read the cold boot process specifically with these X670E boards takes so long because the BIOS is reading/configuring/learning the DDR5 memory characteristics. This memory training could take up to 1 1/2 minutes versus 8 seconds normally.

April 9, 20233 yr you asked me how long it takes, I answered. then you tell me how long it takes lol. why bother asking if you are a know it all? 7900x3d , 64gb 6200mhz 30CL Ram, RTX 3080

CAS36 seems to be the tightest available for 6GHz, but … what is the command rate? Is anyone making it with CR1? Or is everything CR2 or higher? T-Force DDR5 6200 has been clocked to 7000 with a 1C command rate. I think the TForce sticks were Hynix IC's. I haven't been able to research 1C vs 2C on AM5 though. I don't know what kind of real-world improvement in flight sim that would make, if any. Rhett 7800X3D ♣ 96 GB G.Skill Flare ♣ Gigabyte 4090 ♣ Crucial P5 Plus 2TB

" 1) that info was from 1/2 year ago, 2) was wondering what people here had experienced, 3) if that was still the case since newer BIOS updates might have improved that situation 4) your answer didn't help because NVMe has nothing to do with time spend IN the BIOS POST process but only AFTERWARDS once Windows loads. but never mind. I researched further and found that newer BIOS updates have obviously reduced the initial DDR5 memory learning time and is required only ONCE after you inserted new DDR5 modules, not after each cold boot. now we both are know-it-all. 😀 Edited April 11, 20233 yr by turbomax AMD 7800X3D, Windows 11, Gigabyte X670 AORUS Elite AX Motherboard, 64GB DDR5 G.SKILL Trident Z5 NEO RGB (AMD Expo), RTX 4090, Samsung 980 PRO M.2 NVMe SSD 2 TB PCIe 4.0, Samsung 980 PRO M.2 NVMe SSD 1 TB PCIe 4.0, 4K resolution 50" TV @60Hz, VR: Pimax Crystal Light + HP Reverb G2 @ 90 Hz, Honeycomb Bravo Throttle Quadrant, be quiet 1000W PSU, Noctua NH-U12S chromax.black air cooler. 60-130 fps. no CPU overclocking. very nice.
