Dear Customers,

We are happy to let you know that we've just solved the SPI issues.

In the picture below we run only at 1.1Ghz instead of 1.2Ghz because we've hardcoded the voltage at 0.81V and 2 ASICs needed a little bit more.
 

 
Our plan is to tape out the new backplane in 1-2 days, start shipping of X3 on 23rd (after we get the PCBs back and we assemble them). We should be able to deliver all X3s by the end of the month.
