X299 UD4 PRO Loop when booting

[Awusete]

Hi!

I recently bought this components:
Motherboard: X299 UD4 PRO
Processor: i7-7800X
Graphics card: Gigabyte Geforce GTX 1070
RAM: 2x8Gb DDR4 3600Mhz (Corsair vengeance rgb)
HD: SSD Samsung 960 EVO M2
DVD: standard IDE DVDRW

After assembling them, when I power it on, it turns on but I can't see anything in the screen, and it reboots every few seconds. All the time the same. Curiously the RAM I bought has led lights, and just before restarting it turns from yellow to red (I don't know if that is important, but maybe it gives you a clue).

I really don't know what to do. I've been searching online and in this forum but I couldn't find a solution. Maybe some components are not compatible? I was asking before buying and I think everything should work fine.

I would appreciate you help A LOT.

Thanks!

Hi Alex,

What is the specific brand/model of your memory?  Is it on the QVL?
2 DIMMS..  must be installed in the slots on the right side of the CPU socket..  slots F and H (- + - +)

Which slot is the m.2 drive installed in M2P or M2Q?  One drive should be installed in the top slot

The 7800x (6C / 28 Lanes) is supported starting with BIOS F1...  this is probably the shipping BIOS so this is not an issue as your board will have this at minimum.

Below is subject to change based on other devices you have connected but have not disclosed. 

Bench testing is the quickest way to troubleshoot and find problems.  Please verify all connections.  Use the manual.  Sounds silly but anyone can miss a step no matter how many systems you've assembled.

Confirm the above first.  Then...

Three areas to focus on - in this order:

CPU socket
Memory
Power Supply

CPU Socket:
Remove the CPU and inspect the socket for bent pins.  Use a magnifying glass for this unless you have eagle eyes.

Memory:
If you have slower/other RAM you can test the system with, that would be helpful.  If the RAM is not on the QVL and your CPU socket is good, once again look at your memory. 

Power Supply:
A weak, old or damaged power supply can cause boot problems and/or performance issues

Barring a installation error, defect or hardware issue, memory compatibility is suspect here.  Please provide your full system specs...  everything you have connected...  PSU (brand/model), mouse, keyboard (using PS/2, USB?)..  anything else?

Hi!
Thanks for answering!

1- Mi RAM is CORSAIR CMR16GX4M2C3600C18W. It is not in the QVL!  but I can see a LOT of Corsair modules there.
2- They are in the correct place
3- It is installed in the nearest one to the CPU
4- ok
5- nothing else is connected, except the front panel USB and audio, that I also disconnected to test it
6- CPU: checked. It is ok
7- I don't have any other DDR4 to test
8- Brand new Corsair power supply TX850M
9- checked with different mice and keyboards

Maybe a memory compatibilty issue?

Thanks a lot again for your help,

Alex

Greetings,
See my post above.  2 DIMMS should be in slots marked with "+"..  2nd and 4th, not 1st and 3rd.

I do think its the memory.  3600Mhz is somewhat obscure and requires an OC. Move the DIMMS and retest. IN the end however, RAM from the QVL might be the only option.

Hi!
Yes, DIMMs are in the 2nd and the 4th
I'll try changing the memory. What speed should be the better one for this motherboard and processor?
Thanks again!

Last thing to try..  Insert one stick in the right most slot (4th) farthest from the CPU.  Try to boot. If that doesn't work, you'll have to go with something off the QVL.  2400 or 3200 should be good.  I think the problem is voltage to be honest. If you could bump that, I have a feeling you could use manual settings, but with the current BIOS & memory combination it just doesn't seem possible.
