Hello everyone,
I recently changed my setup and encountered several problems:
The details:
Intel Core I7 6850K
Asus Sabertooth X99
CORSAIR Vengeance LED 2*16 Go DDR4 3000Mhz
KFA2 Geforce GTX 1080 EXOC
Cooler Master 750W 80+Bronze Power Supply
Samsung 850EVO 1TB SSD
First of all, after assembling all the components with the utmost care, as I have been doing for decades, I notice that the POST loading is quite long, which surprises me greatly considering the quality and performance of the components used. After 10-15 seconds of waiting, the "Sabertooth" LOGO appears and the BIOS loading begins.
And then, a second problem arises: I realize that only one memory module is recognized, so I go about testing each DIMM slot on the motherboard with each of my 2 memory sticks.
The verdict: the 4 slots located to the right of the CPU socket do not work. I think the problem must be related to the BIOS version, so I put the 2 sticks in 2 of the 4 slots on the left and decide that I’ll take the time later to update the BIOS.
Aside from the incredibly long POST loading, everything goes well, the PC works fine but something feels "off."
Two weeks later, BAM, the PC suddenly turns off, then restarts but without any image, that pesky "no signal" that haunts us all is messing with me.
I see that the "CPU_LED" stays lit in red, which would suggest a CPU or motherboard error. No way to bring up the BIOS, I’ve tried EVERYTHING.
All the fans are spinning, the LEDs are on, the heatsink is turning and is well secured.
The power supply works; I tested it in another machine.
Changing the memory module positions doesn’t change anything.
Unplugging all peripherals and SATA sources doesn’t change anything.
I removed the CPU to check for signs of overheating, looked for any bent socket pins, nothing to report.
The problem is that I don’t have another motherboard or CPU to test with, and I can’t afford to buy others for testing.
The question I have is:
Is it the motherboard that was weak from the start and let me down, or is it the CPU that did the same?
Has anyone else experienced exactly the same problem?
Can professional technicians tell me where the problem lies just by reading this post?
Thank you for reading, and thank you in advance for your responses.
Best regards,

Good evening!
I read the post.
I had exactly the same problem (back from vacation, I put the system SSD back into the machine (I don’t like leaving my personal data remote, don’t ask)) and crack: my x99a sli plus and its 5820k no longer want to display anything on the screen.
I did everything, and indeed, at that moment, the right DIMM slots were failing the BIOS.
So I put in my secondary card (an HD 5450 that only needs a PCI-e 16 port) as the priority instead of the GTX 780, removed all the peripherals (like you) and played with just one stick in slot 1 at boot (I obviously played all 4 test games: 1 per stick). After 10 million BIOS resets (at least), miracle: it works again. But my overclocking profiles didn't all work (especially on the RAM, the CPU... nothing wrong) and the right DIMMs... if I had the misfortune of using them, back to square one. Basically, the same hell as you at first, but with the startup finally showing its face in the end.
I should have sent my motherboard for repair, but I finally gave up: BIOS update, clean reinstall... and I don’t remember after how long, the BIOS finally accepted the XMP profiles and the right DIMM slots. I didn't understand why this happened, but that's how it is.
I don’t know if this can help you: I still haven’t understood why my setup threw such a tantrum overnight.
At least, I am reassured: another user of the x99 platform had the same problem. On a different brand and model motherboard, with a different generation processor, higher frequency sticks... but with the same chipset.
Have a good evening

The 3 biggest lies of a dev:
1. The doc? We'll do it later... 2. The program has been tested and has no bugs... 3. The technical specifications are finished...

Hello everyone, and thank you for your responses.
I conducted one last test, by removing the RAM and the graphics card, leaving only the processor, the 24-pin ATX, and the 8-pin ATX connected.
No beeps, NADA. Whereas I had just done the same thing on a functioning machine, where I got a long beep + 2 short beeps that repeated in a loop.
No beep = faulty motherboard, we agree.
Thank you all for following the topic, I am now 99% sure that my problem comes from the motherboard.
Best regards,

The problem on my end is that no matter what I do, this "CPU_LED" that is supposed to indicate an error during POST BOOT stays lit, no matter what I try.
I attempted a CLEAR CMOS, nothing... I even removed the cooler to touch the processor with my finger; it doesn’t feel warm at all, as cold as ice.
I even installed a speaker, and no BEEP... NOTHING
Should I conclude that the processor is dead?
Is it the motherboard socket that no longer supplies power to the processor?
I don't know of any other way than to install another processor on my motherboard, but unfortunately, that's impossible for me...
Thank you again for your reply.
Honestly, I think the best thing would be to contact your retailer/customer service/similar to see what can be done. If the warranty still covers the components (which it should, 2 weeks... you know).
So contact customer service and ask for assistance with sending the components. You’ll just need to find a box that is big enough and sturdy enough to transport the motherboard and its box, the processor and its box, and maybe even the RAM sticks (if all these components were purchased from the same retailer).
What’s strange is that my setup had exactly the same symptoms. I just had to install one single RAM stick in one of the left slots (yay for the 16 combinations, can you imagine), turn off the power for 30 seconds, and then do a Clear CMOS right after, and off we go!
