Question New build sometimes hangs on boot, with Yellow DRAM light on motherboard ?

[joshperson]

Very intermittent issue that I'm having. PC runs great outside of that. I'm not even sure where to start. I did MemTest86 that ran for 2 hours and came back fine.

Build:

i7 13700K

64GB Teamgroup T-Force Delta DDR5 6000Mhz

Gigabyte 3080 RTX

ASUS ROG STRIX Z790H Gaming Wifi

MSI MPG A1000G

Only thing left over from old build is the 3080. Everything else is new. I would very very rarely get something similar to this on my old build. That was once every 6 months it seems I'd boot up and my keyboard wouldn't work. This new problem is every couple of days and I'm getting nothing to my keyboard, mouse or monitors. Any help would be appreciated.

Someone elsewhere mentioned "It might be memory training. Go in to your ram settings in the bios and set Memory Context Restore to Enabled instead of Auto". But I couldn't find that in the Asus BIOS. Not sure if it's called anything else.

Disable XMP memory overclocking (at 6,000MT/s) if it's enabled. It might increase stability.

Try removing the 3080 and use the 13700K iGPU, to discount problems with the PCIe card.

Do you have 4x16GB DIMMs or 2x32GB? Two DIMMs are usually more stable than four.

Is the latest BIOS installed?

Thanks for the response! I do have XMP enabled on the first XMP profile and I also have 4x16GB. Had this problem before I added the two extra sticks though. I did install the latest BIOS upon build 2 weeks ago.

It also seems to happen after I update windows or windows store items more often than not. Not sure if that’s even a possible thing.

Two DIMMs are often more overclockable than four DIMMs with XMP enabled.

Even with only two DIMMs installed, it's not 100% guaranteed you'll be able to overclock up to 6,000MT/s in every situation.

Try switching off XMP and see what happens. I'm running 2x32GB DDR5 at 4,800MT/s on my 7950X rig for stability in video rendering. My apps hardly benefit from RAM overclocking.

I turned XMP off and it stalled again after a restart. DRAM light on again. One of the RAM sticks RGB was different from the others this time. Looks like I probably just have to take out the first two sticks I installed since this problem goes back to the beginning and see if I'm still getting problems.

If one of the sticks of RAM is different, that could explain the problem. Ideally you need a quad set of matched DIMMs, not two pairs of supposedly identical DIMMs or a glorious assortment of any old memory.

Start again with just two sticks from the same set in A2,B2. Run MemTest86+. Only if you get a clean bill of health should you start testing with Windows. Good luck.

They are all identical. Just bought 1 week apart since they were on sale. Not sure if one stick of the original two are having problems, but I guess we'll see. Was hoping a BIOS setting was the cause since my CPU fan blocks two of the RAM slots.

Update!

Took out the two original RAM sticks and took a pic of BIOS before and after. Under "Information" my Memory was for some reason showing 3600MHz when I had them all installed, but now that I took out the first two sticks it's showing 6000MHz. So I'm guessing one of the original sticks was messed up?

Well so much for that. I hung on boot again. When I manually powered off and back on the BIOS under Information the Memory said (DDR5 4000MHz). After another reboot it was back to 6000MHz. This is with different memory sticks. Not sure where to go from here.
