[Solved] - Aorus X470 Ultra Gaming - does not turn on, the CPU LED is blinking

Best answers

Why won’t my Aorus X470 Ultra Gaming motherboard POST with a Ryzen 7 2700X and G.Skill DDR4-3200 RAM, showing a blinking CPU LED?

The most likely cause is an outdated BIOS: an older F2 BIOS may not recognize the Ryzen 7 2700X, and updating to F4 solved the same no-POST/CPU-LED problem. [#17403700][#17411318] One reply noted that the board should have supported 2nd-gen Ryzen, but a stale BIOS can still prevent startup, and the issue was fixed after the seller flashed a newer BIOS. [#17403680][#17411318] The RAM was less likely to be the root cause, since the board would not even POST with no RAM installed, which points more to CPU/BIOS detection than memory configuration.

    Yesterday I bought an Aorus x470 Gaming Pro board and RAM DDR4 G.SKILL 8GB 3200MHz Ripjaws V Black CL16 (2x4GB). After connecting everything, the computer starts up, for one or two seconds the fans go faster, then they slow down sharply (still spin), the red CPU LED is on. Speaker doesn't say anything, but maybe I plugged it in wrong. The monitor does not get any signal, after turning on the computer the CAPSLOCK key on the keyboard does not turn on the "light"
    I made sure that the processor was well connected (4 pins each on both slots), and all the cables were in contact, including those at the power supply. Mainboard power supply also well connected.
    The processor works, heats up. All the windmills are working. The Aorus logo on the disc remains lit when turned off.

    Full computer specification:
    X470 aorus ultra gaming
    RAM DDR4 G.SKILL 8GB 3200MHz Ripjaws V Black CL16 (2x4GB)
    Ryzen7 2700x processor
    SilentiumPC SUPREMO FM2 750W power supply
    Aorus 1060 6gb Xtreme edition graphics card (I also tried the backup - MSi GT210, I connected both DVI and HDMI)

    I tried with both dice in different slots, 1 and 3, 2 and 4, I tried with a single die in all slots.

    The board supports 3200 RAM, but my model is not on the Aorus website in the list of supported RAMs. Do you think that this is clearly the fault of the framework and when I buy a supported one from the list, the problem will disappear? Any advice, something else to try?

    I intend to send back the purchased set to Xkomu, collect the money and in the near future buy the whole set from scratch, with 16gb memory supported

    And is POST CODE displayed on the screen? If so what?
    You can enter the BIOS and set everything to auto or try to manually enter your RAM bones.

    I wrote, the monitor is not getting any signal. The windmills are spinning, the motherboard it is on, the processor heats up, but zero signal to the graphics card, the keyboard and mouse also get no signal, only power (keyboard backlight)

    Hello

    You probably got a speaker for reading error codes with the disc. Plug in and say how it squeaks. (in the manual you have how to connect)
    Then remove the RAM and check it squeaks.
    Did you use plastic spacers when mounting the motherboard to the housing?
    Are all power connectors plugged into the correct places? On the board you have a large 24pin cube and a smaller one at the processor.

    CPU cooler plugged into CPU_FAN socket?

    best regards

    I'm afraid she won't tell you anything, and it won't even be beautiful. I am processing the same problem already on a second motherboard the same as yours. Everything is plugged in properly, the fans and backlight are working, and it doesn't even POST and there's no sound. The CPU LED is blinking, which would indicate that the processor is not working properly. It seems that bIOS does not recognize it, although apparently the X470 are already supposed to be adapted to the 2nd Generation Ryzen (I just have a 2600X)

    Remove the motherboard from the case and check the correct assembly of the processor.
    The processor is properly inserted and closed in the socket as well as the cooling assembly.
    All this is done on the table the motherboard itself, the processor and the processor cooler.
    Then put the jumper in CLR CMOS for 10 seconds, then remove, no power may be connected during this procedure.
    Install the motherboard in the case with the CPU and its cooling with one RAM chip.
    Connect only the power supply cables to the motherboard, front panel cables and the system speaker.
    The rest is redundant.
    Connect the power plug to the power adapter.
    Switch on with the switch on the housing.

    None of this works. I've tried several times. on both records. Rather, it looks like the board has a slightly stale BIOS that doesn't recognize the CPU - the Ryzen 5 2600X. If the board is older than the release date of the 2nd generation Ryzen, it probably has too old BIOS to recognize the processor. Unfortunately, I do not have an older processor compatible with this board to update the BIOS and then mount Ryzen. for now I have given the disc to the seller who will try to upload a newer BIOS. By the way, it's a bit weird that a motherboard based on the X470 chipset wouldn't support this CPU, as it was supposed to do. I bet, however, that I got a copy from stock.

    On the manufacturer's website, the rev 1.0 motherboard, the first F2 bios release, supports the Ryzen 7 2700X processor.

    That's why it surprises me. Meanwhile, it looks like my motherboard is not detecting the CPU and is not even starting a POST. I connected it to the 800W Chieftec and 600W power supply, all cables are properly connected (I am sure of that, both the 8 and 24 PIN power cables and the entire front panel), the graphics card fans, CPU and board backlight are working. The diode indicating incorrect operation of the processor and RAM blinks alternately, and sometimes only the processor diode is on. I tried to fire a CD with 1 RAM die in a slot (I tried all the slots in turn) and 2 dice according to the board's specifications. I also fired without RAM and did not even deign to signal the lack of memory. The processor is inserted correctly (it cannot be inserted incorrectly), the cooling is also mounted solidly and stably and connected to the CPU FAN. I tried resetting the BIOS with a jumper and by removing the battery. Nothing works.

    According to the motherboard manufacturer's website, your memory supports only slots 1 and 2 !!
    And in the description of the first post, this combination is not mentioned ;)

    I tried that too. I have practiced all possible combinations, both with one die and with two. It did nothing

    Maybe it's a matter of unsupported frame bones. I am exchanging my g.skills for the supported Hyperx Predator 16ths and see if it will be okay. People wrote that changing the memory to the supported one helped

    Maybe it's a memory problem, but at a later stage. POST should probably start even without RAM and signal its absence with beeps, and for me, even POST does not start.

    [quote = "fox"] Works with Ryzen 7 2700x with these RAM (DDR4-3200 G.SKILL Trident Z model: F4-3200C15D-16GTZKW)

    But as I can see you already have the BIOS version F4, which is the latest after the update. I'm afraid mine still has F2. I can't check it because ... BIOS and POST won't start ;)

    So far, my motherboard has gone to the seller who is to download a compatible older processor and try to upload a newer BIOS. We will see what the effects will be.

    Cool, but how to set it up without a BIOS? ;)

    Added after 7 [hours] 14 [minutes]:

    Problem solved. The album came back with a new F4 bios and it runs nice. Apparently, the F2 BIOS can't handle second-generation Ryzen. My predictions turned out to be correct. Thanks everyone for trying to help :)

FAQ

TL;DR: On this X470 board, 1/1 confirmed fix was a BIOS update; “F2 BIOS can’t handle second‑generation Ryzen.” Update to F4+ to stop CPU LED blinks and no‑POST. [Elektroda, sonn, post #17411318]

Why it matters: This FAQ helps AORUS X470 Ultra Gaming + Ryzen 2000 owners fix CPU LED blinking, no display, and no POST issues.

Quick Facts

What does a blinking CPU LED on the X470 AORUS Ultra Gaming actually mean?

It flags a CPU initialization fault. One user observed a blinking CPU LED with no POST, suggesting the BIOS didn’t recognize the CPU. “The CPU LED is blinking, which would indicate that the processor is not working properly.” This matched a Ryzen 2600X case. [Elektroda, sonn, post #17402941]

How do I fix no POST with Ryzen 5 2600X/2700X on this board?

Flash the BIOS to F4 or newer. After a vendor update to F4, the board posted and ran normally. “Problem solved… it runs nice.” If you cannot POST, arrange a service flash. [Elektroda, sonn, post #17411318]

Could two boards with the same symptom still be fine?

Yes. One user saw identical CPU‑LED and no‑POST behavior on two new boards. The root cause was firmware, not hardware. Updating to a newer BIOS fixed it. That indicates duplicates can share a BIOS issue, not a defect. [Elektroda, sonn, post #17402941]

Will it beep without RAM installed if I connect a speaker?

It should. Connect the system speaker, remove all RAM, and power on. Lack of beeps then points to an earlier POST failure, often CPU or BIOS initialization. Ensure the speaker is on the correct header. [Elektroda, icosie, post #17401453]

Which RAM slots should I use with two modules on this board?

Follow the board’s QVL notes for your exact kit. One post highlights that a listed kit was validated in slots 1 and 2. Try that configuration before 1+3 or 2+4. [Elektroda, Longin001, post #17405180]

Does non‑QVL RAM stop the system from posting?

It can hinder memory training at XMP speeds, but many systems still POST at JEDEC. Users report success after switching to supported kits. In another case, the BIOS update—not RAM—was the fix. [Elektroda, humbas, post #17411102]

How do I clear CMOS correctly on the X470 AORUS Ultra Gaming?

Power down and unplug. Move the CLR_CMOS jumper for 10 seconds, then return it. Reconnect, install one RAM module, the speaker, and only essential power, then boot. This resets configuration to defaults for troubleshooting. [Elektroda, adamadi33, post #17403630]

Which power connections are required for first boot?

Seat both the 24‑pin ATX and the 8‑pin CPU power connectors. Install the CPU cooler on CPU_FAN. Verify front‑panel leads and the system speaker are connected correctly. [Elektroda, icosie, post #17401453]

Why do fans spin and LEDs glow, but there’s no video or Caps Lock response?

That pattern matches power-on without successful POST. The report included a red CPU LED, no display signal, and Caps Lock not toggling. Focus on CPU detection, BIOS version, and speaker beeps. [Elektroda, humbas, post #17401347]

Is Ryzen 7 2700X supported on BIOS F2 for this board?

A post cites the manufacturer stating rev 1.0 with BIOS F2 supports the Ryzen 7 2700X. Check your stickered BIOS or have it flashed if uncertain. [Elektroda, adamadi33, post #17403700]

Why doesn’t it beep even with RAM removed?

If CPU initialization fails, the board never reaches the RAM check, so no beep occurs. One user noted, without RAM, it still remained silent, confirming CPU or BIOS stage failure. “Did not even deign to signal the lack of memory.” [Elektroda, sonn, post #17403742]

What DRAM voltage should I try while troubleshooting a 3200 MHz kit?

Use Auto/JEDEC first. The Ripjaws V 3200 CL16 kit has XMP at 1.35 V, but start at 1.2 V until stable. “1.2 Volt recommended for the board.” After stability, enable XMP. [Elektroda, lisek, post #17411309]

Is my PSU wattage the likely issue here?

Unlikely, if sized reasonably. One case used 800 W and 600 W PSUs with identical no‑POST behavior. That points away from wattage and toward firmware or CPU detection. [Elektroda, sonn, post #17403742]

I can’t enter BIOS to flash; what are my options?

Ask the seller or a service center to flash a newer BIOS for you. This path was used when the board would not POST with a Ryzen 2600X installed. [Elektroda, sonn, post #17403680]

What does alternating CPU and DRAM LEDs indicate on this board?

It suggests failing CPU and memory training loops. One user saw CPU and RAM LEDs blink alternately, then no POST. Address BIOS version and CPU recognition first. [Elektroda, sonn, post #17403742]
