DRAM led red adding new ram kit before first POST

DRAM led red adding new ram kit before first POST
« on: April 07, 2019, 02:38:03 pm »
Hi guys,
i need your opinion about a problem. Yesterday I added 2 new sticks of RAM getting no POST: all the fans were working but the DRAM led was on with red light; because of usually PC takes few seconds to POST, i've immediately thought about a problem and turned PC off. So I removed the new sticks and try to POST again getting the same thing: this time i waited little more (about 5-8 seconds i think) and i heard hard disks working; then the speaker beeped and the system POST, DRAM led turned off and OS was loaded.
Then i reseated the new RAM and again got DRAM led on and no video signal: waited for few seconds and everything started to work. I checked BIOS and windows events and no error was found: all 32 GB of ram were recognized by windows in DUAL CHANNEL (as CPU-Z swhowed).
All the sticks are 4x8 GB Crucial Ballistix Sport PC4-19200, the other components of my system are:
-H370 Aorus Gaming 3 wifi (BIOS F11)
-Intel core i5 8600k
-Cooler Noctua NH-U12S
-GPU GTX 1050 Ti Zotac ZT-P10510A-10L (drivers updated)
-SSD Crucial MX500 250 GB
-HD Western Digital Blue 2TB
-HD Western Digital Red 3TB
-PSU Seasonic focus+ gold 650
-case: cooler master N300
-fans: 140 noctua front intake, 120 noctua back exhaust and 120 cooler master top exhaust

I tried to reboot and turning PC off-on few times, but this time system POST immediately so i'm little confused: is it possible that every time you remove/reseat ram BIOS needs 5-10 seconds to initialize memory? Just a little worried about motherboard DRAM red led, not a good sign: moreover i don't remember if i got the same behavior when i built PC months ago, placing former 2 ram sticks.

Thank you very much

Greetings,
Is your RAM on the QVL or not?

If its not one of these kits, then it might not be compatible or supported.

Sometimes you cannot use XMP and have to enter the memory timing, voltage, etc manually in M.I.T. 

The DRAM LED doesn't indicate something is damaged.  It indicates a failure of a system check.  In this case memory.

Once corrected the system performs another check and if corrected, the error clears, the LED turns off and the system moves to the next check or boots.

SPD detect can set certain BIOS parameters automatically.  If the system doesn't start, it might take additional time 5-10 secs for the settings to correct.  100% normal.

All the modules are: BLS8G4D240FSC, i know it's not in QVL but the note says: " Memory modules listed as above is for reference only. Due to massive memory models in market, we can only verify some of them."
Moreover crucial declares: modules BLS8G4D240FSC, BLS8G4D240FSB, BLS8G4D240FSE just differ in heatsink color: my modules are white, while B grey and E red, so i think my sticks are compatible with motherboard.

Anyway from your last sentence i could supposte when you seat new ram, it's normal the BIOS can take a little time to initialize new modules? Unfortunately i don't remember if the same happened first power-on when i built the system last summer about the first 2x8GB ram pair: maybe i was more concentrated to make sure no smoke get out from the case  ;D because was a long time since my previous pc build.

Thank you very much

They do appear to be identical

Crucial isn't known for its universal compatibility.

Try inputting settings manually.

16-16-16-39 1.2v

May also be helpful to load BIOS defaults, then make the manual settings.  Power down and install the memory.
