Please reduce the board frequency to 487.
If the issue is not solved Please try reloading the firmware:

Run the miner for 20 minutes after loading.
Please first check the PSU and the controller. To check the PSU you can test the machine with a known good PSU. If you do not have another PSU then check by switching the cables between hashboards. If the issue follows the cable then the PSU may be faulty. Please reply to this email for more instructions.
To test the controller, switch the controller cables between hashboards. If the same hashboard shows the issue then the hashboard is faulty. If the issue follows the cable then the controller may be faulty. Please contact us for further instructions.
If it still is not solved please test each hashboard separately to determine which one is defective.
To test each hashboard separately: keep the PSU connectors and controller cable on one of the hashboards connected and disconnect the cables from the other two hashboards. With the miner running you can see the status of the connected hashboard.
Here is more detail: http://support.bitmain.com/hc/en-us/articles/226142788-Testing-hash-board-one-by-one
On the miner status screen defective chips are displayed as "xxx", "---" or " ASIC≠60
Once you know which part is defective please create a Repair ticket and ship the part back to us according to these instructions: https://shop.bitmain.com/repairGuide

Please pack the hashboards carefully. If the PINs are lost due to shipping damage it will void the warranty. Here is a video demonstrating how to pack the boards: https://youtu.be/Z0LdykALhxI
You may disassemble the miner and break the warranty seal under the instructions from this article

I have the same problem,
I have at least 10 D3 miners with missing chains.

and i need solutions
Same problem here. 28 units running at 2 different sites.
Firstly I see some still active, but today all went offline (both site simultaneously).
Some miner are hashing but antpool show disabled. Was there other report of pool issue? Will also file support ticket with details.
Secondly for past week need reboot 50% or machine every few hours. Some showing less hash card then others aka 2 chains with or xxxxx on chips. I checked that all my machine not on latest FW will flash and check again. Will leave an open support ticket till resolved. Thanks!
It will Be nice if customer can be notified of releases of FW
I have the same problems, I have D3 miners with missing chains or a single "x" and then I reboot and it shows another error i.e. missing columns in ASIC status.
I have e-mailed several times and had nor reply with a solution.
I updated latest firmware but still errors are occurring.
I have also had payments which are showing as being paid withdrawn and NOT paid.
I have sent several screen shots.
I don't know what's happening.
