ROG MAXIMUS Z690 FORMULA Memory detect issue.

[ssstrong]

Hello, i have current build of

12700KF
Rog Maximus Z690 FORMULA
RTX 2070 SUPER
850 WATT PSU MSI GOLD
ADATA 4800 DDR5 16 GB X 2 inserted in A2/B2 slot

I have this build for 8 months without any issues.

Things started one week ago during play VIDEO game, the screen freezed and restated without any blue screen. After couple of days same thing happen during game but this time i could not get the computer to boot. It was showing me error "Memory detect" in the mother board small screen.

I get it to boot up again by changing ram slots to A1/B1, now working fine even during gaming, no crash no freeze but the speed is 4000 not 4800 as it was before.

I changed it back to original slot. Sometime it doesnt boot up and showing memory detect error. Sometime it boot up but would freeze and restart during playing video game or any demanding tasks.

Now if i put single ram in A2 slot it show me memry detect error, single ram in B2 slot work fine but also the speed is 4000 not 4800.

Could it be the A2 got defective ? Or the ram defective because of higher speed of that slot ?

Thanks


------------------------

Edit: found solution.

I tried to loose the mounting pressure and it worked fine for couple of days then get memory detect again.

so last thing i tried i get the Thermalright Intel 12th/13th Generation LGA1700 Anti-Bending Buckle, things are working fine for one month, i get Gskill 6600 16GB X 2 and so far no issue.

I hope this would help anyone getting the same issue.

Hello

I did multiple trial by removing the ram and clear cmos.

I put it now in A2 B2, it works now and show speed of 4800 and i enabled XMP I and showed me speed of 6600.

But the problem happened in the two condition that after login to windows the system freeze and crash while playing video game or doing CPU-Z stress. (This doesnt happen when the rams using A1 B1 whit 4000 Speed)

Its really wierf issue and i dont know what or where the problem or what to change

The overclock is unstable. *

Try switching to XMPII

6600 can be tough for 4 DIMM boards on 12th gen.

Using defult mode 4800 also causing crash and freeze during stress or gaming.

XMP II causes the computer to freeze and crash at login screen. While XMP I at stress crash

It seems like anything over 4000 would cause crash

I updated to the latest firmware available in ASUS website including intel management engine and rapid storage.

the new thing that putting single ram in B2, works and with speed of 6600mhz and without any crash or freeze even after 5 minutes of CPU-Z stress.

but the problem putting another ram in A2, it wont post. putting single one in A2 also won't post and showing "Memory Detect" A55 .

tried default, xmp1, xmp2. the same result.

any help would be really appreciated.

if the system is crashing at optimised defaults then something isn't right. If possible, take the components to a system integrator to test for you.

The problem is with asus and their latest bios breaking xmp, I'm confused why mods around here are dancing around this issue..

Optimised defaults does not apply XMP. Please only respond to the thread unless contributing.

Hello

He told me it's motherboard issue and we don't have asus service center here so either keep it like that or throw it away

[ssstrong]

Guys, any help would be really appreciated, I live in a country with no ASUS service center or warranty, I bought this MB with 750$ before 11 months a and now get this weird issue. I don't know weather its MB issue or some bios tweak or something else.

So if is MB issue I think I have to throw it away.

Hello guys, can you look at this video please

[ssstrong]

Any help please ? Should i just throw the MB away and get another one ?
