Question Red CPU and Orange DRAM light

[kyos]

hi
i build a new pc and when i started it for the first time i had ram installed in A2 and B2 slots as advised but i got a fast red cpu light then a longer orange dram light and they keep cycling like that A2+B2 then i tried with only one ram stick in each slot and when i put it in the A1 and A2 it blinks fast red cpu then it stays a constant orange dram lightA1+A2 but when i put it in the B1 and the B2 it does a fast red cpu then a couple of secs of orange dram light then it turns off for a seconds and i get a white vga light then a green boot light after secs B1+B2and i get image and everything works well i updated the bios then installed windows 10 and installed cpu and gpu drivers .
then after that this is what i tried :

• replugged psu connectors and changed their psu slots
• reseated cpu
• removed all unnecessary cables

but still the same . i wanted to ask if anyone knows anything else i can test before returning the motherboard beacause i think it is the problem. notes :
1-when i open then task manager it is detecting the other 2 slots A1 and A2
2- i tried with 3 rams B1+B2+A2 and i git the cycling red cpu then orange dram light like in A2+B2
3- one time i forgot to plug the 8+4 motherboard connector and it didnt give me image ofc but there was no orange dram light even tho it was A2+B2 slots installed.
specs:
mb : asus tuf gaming z690
cpu : i5 12600k
psu : asus rog strix 1000w

With Ryzen systems sometimes weird detection memory issues are caused by cooler being too tight, or uneven, though you did say you'd changed it at least once. It could be worth a try, even though it's an Intel build, if you have the kind of cooler that is manually tightened.

If I understand you correctly, you're saying that B1 and B2 works, but no other combination? So, only one channel?

What's the memory, by the way?

check your motherboard manual or go toasus website support. that orange light is the memOK - staying on is trying to train w/ram. sometimes it will reboot while trying.

if you're having a fail - it points to the ram being bad.

what is it?

This is not an Amd only problem, Intel LGA 775-LGA 1700 exhibit the same exact problem if the heatsink is too tight.

I think the ram is a dud.

Best thing to do is get to shop and have ram tested.

yes B1 and B2 only working without dram problem.

i have 2x 16gb 3600hz corsair vengeance Lpx.

nothing about it in this mb manual it's more of an installation guide

motherboard is : ASUS TUF GAMING Z690-PLUS WIFI D4

tried with a different ram and same problem so it's not the ram.

yes B1 and B2 only working without dram problem.

Another possibility to only one channel is a broken pin, but I assume you checked that when you reseated the CPU. No thermal paste on the underside of the CPU too.

Check orientation of cpu, check lga pins, clear cmos.

yeah when i reseated the cpu i didnt see broken pins

So whats going on?

I have this exact problem did you find out what it was?

For anyone that is still having this problem after like hours of troubleshooting:

First I followed basically every single step I found online except checking my power supply. I had just updated to am5 so I have a new cpu, ram, and mobo which means that I cannot swap parts out to test them.

I took out the right stick of ram so I was left with one stick, still nothing happened. I used compressed air on the slots and used a paper towel and 70% isopropyl alcohol on the ram stick connectors then plugged the stick into the slot that gave me the error code (orange, then red, then white) and it BOOTED.

tldr: use compressed air on the slots and 70% isopropyl + paper towel on the dram pin contact area. and pray that your boot led turns green. If it does and you get a thing that says "New CPU installed, fTPM/PSP NV corrupted or fTPM/PSP NV structure changed." just press Y (worked for me ¯\_(ツ)_/¯).

If this doesn't work then good luck soldier o7

@fourital shouldn't have to do any of those steps unless it's a old dirty motherboard. If it a brand new one and these steps are required, send it back because something is very wrong.
