ASUS Crosshair VII Hero won't post

Hardware Hub

Hey everyone,

After six years I found it time to build a new rig. My trusty i5-2500K will be passed on to my wife once my build is finally finished.

As per forum guidelines I used pcpartspicker.com to show you what I put together:
https://pcpartpicker.com/list/Qx77gw

Currently connected to the MB is the following:
CPU + cooler, MSI GTX 1060 - 6GB, Acer monitor using HDMI, RAM and an old dell USB Keyboard.

The problem that I’m having is that as the pc is booting it stops at a certain point, the green LED lights up (BOOT) and I’m given a nice generic code 0d on the display.

I tried starting up with 1, 2 and 4 ram modules.
I tried starting up with my new GTX 1060(6gb) as well as my old GTX 760(4gb)

At the start I had both m.2 drives in and both SSD’s. I have since dropped/removed all

I also updated the bios to v1002

I’m still not getting a post. The screen is dark, no beeps just the green LED and dreaded 0d hex value on the debug display.

I’ve read the RoG forums and someone was talking about a “BIOS reset” button and pressing that, holding start until the debug q code’s start coming up but I’m uncertain as to what button is being referred to in the post. I have tried some combinations but alas, still no post

I put a lot of time and effort in this build and this whole evening has been enormously disappointing. Picking premium parts for this build I didn’t expect to run into any troubles. I guess I got what I deserved by assuming that (insert ass-u-me - meme)

I hope someone here can help me out with this issue, I’m at a loss right now

hmm … sorry to hear you are having troubles.
you have tried a lot of the important steps already

  • First the obvious question: both ATX 24 pin and CPU power cable are plugged in right?
  • do you have the front panel headers connected at the moment? (try without them)
  • Have you tried posting without GPU and keyboard? (only looking at the post code, it should not really matter at the start of the post sequence but who knows)
  • Try re-seating the CPU and check the orientation.
  • Are you certain the bios did apply successfully?

I can’t think of more at the moment, doa hardware is rare but maybe it’s a bad board. I’ll also need to look up the correct post code sequence again to know what should happen at what stage. It has been some time since I looked at that.

I’ll follow up tomorrow, I’m too tired right now. Good luck with troubleshooting in the meantime.

also, I added a helpdesk tag

At this point with a new build that doesnt post, it is time to troubleshoot. Start with just mobo, CPU and cooler, 1 stick of RAM in the appropriate slot (see mobo manual, as they are all different, GPU, and PSU. Make sure 24 pin ATX, CPU and PCI power to the graphics card are connected. See if it posts.

If the system posts with only these core components, the problem is with something else. Connect one component at a time, and test for post after each one. At the point the system no longer posts, the problem will be more clear.

If the system does not post with core components, as mentioned above, we will have to do some other tests to narrow down the problem component.

There is another way to make sure that you do a bios reset properly.

  • Unplug the system from wall power.
  • take the bios battery which is on the motherboard out for a few minutes.
  • put the battery back in again.
  • plug wallpower in again, and see if it wants to boot then.

Sorry to hear of your troubles. Don’t have a lot to add the others have not already so well coverd. But, definitely worth re seating your ram and using just two modules - In DIMM slots B2 and A2. I had some issues running four DIMMs which cleared right up when using two DIMMs.

Qcodes 0C-0D listed as reserved for future AMI SEC error codes… nice help, I know right? Do you have any other diag lights present besides the green CPU ready?

I tried this with each of the four sticks that I have and all of them resulted in a 0d. Next to the green led, the white led was also on because I didn’t have my gpu in anymore

Edit: Clarification: I put the one stick in the A2 slot as per user manual instructions

Have you tried with only

yet and checked if you get a different post code?

In case you still get the same code you’ll need to take the CPU out (take care, the CPU can get stuck to the cooler, best slide the cooler off sideways), check if the orientation of the CPU is right (not sure if it’s possible to insert it in a wrong orientation) and then inspect CPU pins and socket for defects. If you don’t see anything wrong in that case you have most likely a doa motherboard and need to get a RMA.

Status update:

I went to the store where I bought my components. Had the ram out and tagged as to not mix both sets.

Guy at the store puts in random cheap as mem -> PC Posts
I’m not getting it, told him I tried to put in each of my modules without success

He puts in the first he finds -> PC Posts
He adds a second one -> PC Posts
He adds all memory -> PC Still posting

¯_(ツ)_/¯

PS The Bios Update I did earlier (without ever having a post) was successful \o/ woot

Yeah, technology is strange sometimes. I guarantee you the tech aura is real! Computer components feel that you mean business when you threaten them by bringing them to the store or a tech of some kind. :grin:

Anyways, I’m happy your rig seems to be working now. Have fun with it! :sunglasses:

I’m getting lost in the settings

According to the Asus Site the C7H supports DDR4 upto 3200, but my bios is showing me speeds up to 4000, I now regret not having bought DDR4-3600

I’m also looking for more info as to what the settings mean and how I should configure my main board to get most/safest performance out of it.

I ran the EZ OC wizard, which clocked my CPU at 3800+Mhz but my mem is stuck at 2197Mhz, I’d expected it to bring it at least to 3200

If you have any pointers to resources on the matter, I’d love to hear/see them

You really shouldn’t have regrets, yes Ryzen scales well with memory clock but the benefits are not that big in most workloads past DDR4-3000. Also memory tends to get expensive past 3200.

Personally I had no good experience with the auto memory overclocking settings on Ryzen motherboards but that was on first gen (I have the Prime x370-pro). You pretty much have to input them manually, but it is not that hard and everything works perfectly afterwards.

I’ll need to dig up the site where I got my settings, can’t find it right now…

please remind me tomorrow or on sunday in case I forget about this thead, it happens sometimes

for the Gskill memory you need to set your timings and voltage exactly.
I have the same board and memory.

Match your timings and voltage to this page:

If you can’t hit the timings with all 4 sticks, try it with 2 (in the main slots)

nice to hear that it resolved itself. Though i’d really like to know what the rational reason for that 0D code is.

I do have dead board with that code currently laying around and i couldn’t jet figure it out. It posts to 0D with and without Ram so it might be a different 0D code. …

What ever.

Fingers crossed it doesn’t come back to you.
One common mistake is a standoff in the wrong place.

It might be the same 0D, the guys at the shop use a green Crucial DDR4 dimm, that one always seems to work with any mainboard. So maybe you can try to put in a green (budget?) crucial dimm of ram

The Asus Crosshair Hero VII actually had a 3200 profile, so I just had to load it up, it’s all gucci now
