My friend moved the PC to the kitchen area so it's easier for us to work on the PC. We tried to install his new RAM, which is these RAM pieces: https://www.proshop.no/RAM/Kingston...hannel-2-pcs-AMD-EXPO-Intel-XMP-Svart/3136894

However, upon installing the new RAM (and removing the old RAM), the monitor won't turn ON! Ok, we swapped the slots (we had them on slot 2 and 4), so now they are on slot 1 and 3. No success. Ok, we put back the old pieces. Into the slots, NO SUCCESS! Yes, the PC worked fine before this... And yes, we heard the 2 "clicks" on each side of the RAM pieces upon applying them to the slots, so they are definitely installed correctly. Yes, the PC turns on, and also, his 16GB RAM pieces are RGB, and upon turning on the PC, the RAM sticks to glow...

WHAT is happening and how on earth do we fix this?!

His PC specs:
Mobo: ASUS TUF B650 Gaming PLUS WiFi
CPU: AMD Ryzen 5 7600X
RAM: Kingston Fury Beast 16GB DDR5
GPU: AMD Radeon RX 6700 XT 12 GB
Storage: WD Blue SN570 NVMe 1TB
PSU: Cooler Master 650w GOLD
Cooler: CM ML240
Case: Phanteks XT Pro
OS: Windows 11

EDIT:

Ok, this is odd.... I installed the new sticks to the 2 gray (port 2 and 4), and powered the PC on. Upon starting, there is an orange light on the mobo, that then turned RED after about 10 secs or so. However, after about 1 minute of waiting, the monitor turned on and I could login to windows like normally, and now, there is a green light on it! Doest it mean that I have successfully done it, or?

But, WHY is the PC suddenly so incredible SLOW to bootup? It goes through the orange > red > blue > green light process again before it starts up. Takes about 40-50 secs.. which is TOO long! HOW do I enable fast boost again??

Is it slow to boot because the sticks seems to be mismatched? Because look at these screens and you will see that each of the sticks have different values. HOW do I fix that? :O Here are some screens that I hope will help:

Also, I put memory frequency on AUTO for now..

Personally I would turn off the computer. CMOS Reset. Wait. Press the power button and wait. My previous ASUS prime x670 mainboard took ages to initialise DRAM, especially with outdated firmware.

If that does not work, use a single DRAM stick to the only allowed slot according to the mainboard manual.

Wait means a longer time period as 20 minutes after pressing the power button after CMOS reset. I usually read some stuff on my android tablet while waiting.

It seems you have similar dram as mine: Kingston FURY Beast Black EXPO DDR5 64GB (2x32GB) 5600MT/s DDR5 CL36 DIMM Desktop Gaming Speicher Kit mit 2 - KF556C36BBEK2-64


Can you please specify. Did you run two or four memory stick at one time?
 
check and be positive all your cables and plugs, inside and out are fully plugged in. if thats ok swap out your monitor cable for a new or known good one.

Ah, gotcha. But... how long do I wait when I press and hold down the CMOS Reset button on my mobo? Thanks for the tip! Will try this.

I ran 2 sticks at once.

EDIT: Shoot, I cannot locate the CMOS Reset button on ASUS TUF B650 Gaming PLUS WiFi.... :O Here is the mobo. Does it even have one? I tried looking anywhere for it, but NOPE! THIS is why I absolutely HATE working with PC's.... Such an easy, straight forward thing, but NOOOO, 50932393 things you first have to do to get it to work. Good grief....

Also, here are the new sticks in place. Does it matter which port they are mounted into (grey or black), or?

use just one stick, you don't need 2 for it to work. Try one at a time. I would update bios and use default values before doing anything else.

Default values on what? Everything? Meaning not activating EXPO and just leave as is, or?

What about any of the other issues I mentioned, particularly that it takes forever to boot because it as if it's "scanning" with the orange, red, blue and green light that appears on the mobo... Will that get fixed with a bios update or?
 

-> Manual

copy paste of the link. I prefer you click yourself on the manual in your language!

page 1-5 13. Clear CMOS header

they named it clrtc on the mainboard

The Clear CMOS header allows you to clear the Real Time Clock (RTC) RAM in
the CMOS, which contains the date, time, system passwords, and system setup
parameters.

page 1-2 -Number 13.

--

Clear cmos. PC should be turned off. Do it for a few seconds or use a hardware jumper for a few seconds.

--

First booting takes time after installing new DRAM. Especially when you have made a clear cmos. Or have bad settings in uefi or old firmware = bios = uefi version.

When you properly set the UEFI the next booting should be fine. Assuming the board behaves similar as the ASUS Prime X670-P mainboard. Also a very low end cheap mainboard from ASUS.

Also, here are the new sticks in place. Does it matter which port they are mounted into (grey or black), or?

Please read teh manual first. I provided you ASUS homepage, and the link for the manual.

Hint: page 1-12 -> Recommended memory configurations

Also, I went into BIOS and changed the frequency from 4600 mhz to 5600 mhz. And I also see that my EXPO is turned off, should I enable it, or?

Please have a look on those Ryzen timings screenshots first.

Some settings need other settings. (Part of the answer. I'll not write use taht voltage with this and that as this may be dangerous when not knowing what you do. And where you do it.)
My DRAM will very often not boot on any mainboard when i raise just the MHz (these days called MT/s)

Kingston FURY Beast DDR5-5600 - 64GB - CL36 - Dual Channel (2 pcs) - AMD EXPO & Intel XMP - Svart​

Minne (RAM), 64GB: 2 x 32GB (Dual Channel), DIMM 288-pin, DDR5, hastighet: 5600 MHz (MT/s) / PC5-44800, CAS Latency: 36-38-38, spenning: 1.25 volt, ikke-bufret, On-Die ECC, støtter AMD EXPO & Intel XMP profiler, med varmespreder, farge: svart

I suggest. CMOS Reset. Bootup with default values. DRAM should run with 4800MT/s (wrong labeled with 4800MHz -> rising and fallinfg flank of 2400MHz to be correct)
check with zentimings that DRAM is really only 4800mt/s default. Update UEFI; Update windows. Check if its stable (out of scope of this topic. there are several topics which cover this for e.g. windows..)

Than bootup uefi -> apply expo profile for

DDR5-5600​

something with 36-xx-xx-xx-xx for the timings
and check before you save and reboot that the voltage is spenning: 1.25 volt for the correct field.

You may download free software called zentimings (e.g. computerbase.de/downloads -> search for zentimings). And check if MEM VDD and MEM VDDQ is 1.2500V for your DRAM. This should bel applied by the mainboard itself when you load the correct expo profile, save and reboot. than enter again the uefi and check it.

-- Do NOT use the ai tweaker menu when you are fresh to the topic. I'm sure this UEFI has a begginer friendly version and an advanced mode. The uefi beginner mode should have less options. The uefi beginner mode should allow applying just the expo profile. I assumed the board behaves similar as my other msi and asus mainboards. Stay out of the overclock and ai tweaker options when you do not know what you do. Sorry - your questions indicate this in this topic. Screenshot shows this. Press F7 and go back in the EZ-Mode.

as in don't change nothing, that's what default means mate.
Start from the beginning not the end, see if that solves it and go from there.
 
Isn't that long boot time normal on AM5?
 
Shut down your PC, turn off the PSU and short these Pins for ~15 seconds with a screwdriver. (CMOS reset)
boot back into the bios, enable EXPO and go to the memory timings tab, around 2/3 down there is a setting called memory context restore which is disabled by default on ASUS boards afaik, enable this.
this will reduce the boot time by ~90% after the first memory training.

AM5 boards can be very slow to cold boot, especially on old BIOSes with early AGESA versions.

Updating the BIOS also does the same thing as clearing the CMOS at the same time, so that would be my recommendation. 30s to boot from an unpowered state is still normal if it's the first cold boot in a while. Look for an option called "Memory Context Restore" and enable it if it's there, it speeds up the slow memory training process by using last known good values.

Wait means a longer time period as 20 minutes after pressing the power button after CMOS reset. I usually read some stuff on my android tablet while waiting.
No need to wait ever again! What you're waiting for is for the capacitors to drain, but you can achieve the same thing by removing the power cord or turning the PSU off at its switch - then trying to boot up the PC with no power. Your motherboard capacitors are now drained and you can reconnect the power; This has worked flawlessly for me for the last 30 years of PC building.

Just the initial training boot, after that it is business as usual.
 
Honestly I have had a lots of issues with xpo/xpm/ etc., etc.

I just get the fastest jedec and let it be happy with 0 tweaking to the memory. I don't have that time to fiddle with that stuff any more.

Just disable all the xpo/xmp, etc. and leave in auto.

Crucial has 6400 jedec now

AMD motherboards can get stuck in a boot loop too. @Toothless knows this well :)

Unplug power when resetting BIOS/CMOS. Install just 1 DIMM and let it boot to the BIOS.

No.

In may 2023 when i bought the ASUS prime x670-p mainboard with ryzen 7600x there was up to 20 minutes boot times after cmos reset with the stock firmware. Or when i set some stupid values for DRAM overclocking. 10 tries to get the DRAM stable costs time.

My 3 weeks old MSI Mainboard X670E Gaming Plus Wifi booted quite fast even at the first bootup.
With the old settings and some tweakings it's quite fast. I'm still on a 4 month old uefi version.

-- the issue is only with mainboards with firmware on them which are 2 or 3 years old most likely

ASUS prime x670-p mainboard - needed several reset button presses quite often for cold and warm boots. Even 1 month ago.

#14 CUDIMM is not AMD compatible. just do not post. Once I read there is sometimes a profile without cudimm. just do not suggest cudimm for AM5. That is my point of view for cudimm with am5 as of now. Feel free to share extra knowledge please.

I think it depends on the motherboard to properly support bypass mode. Even though it should work on everything as backwards compatible, enough people say it doesn't boot or needs a BIOS update, leads me to believe there is more to bypass mode than the whitepapers say. Someone here claimed 7000 series CPUs can't boot them. I have not verified that. But they do boot to 6400 JEDEC at least on the MSI X870E Carbon WIFI using 9800X3D and 9950X. Also have not tried to enabled XMP because 8800 isn't going to post with or without CKD support on that motherboard.

Also CUDIMM on AMD is only in bypass mode, which will NOT provide the benefits of the Client Clock Driver (CKD).

@igormp is using CUDIMM in AMD as well.
