This module just keeps getting better and better and is quickly becoming one of my favourite utility modules. Im expecting great things from disting in the future, however, left a few comments on youtube on some of their videos ermmm ...... the guys @ expert sleepers are yet to wake up on the true potential of these pressing matters.

I'm getting the Unrecoverable Boot Error, when running the test, it shows SRAM failure. Module is out of warranty, so I'm considering trying the repair myself. Is there anyone who have successfully fixed this? I'm thinking the SRAM has to be either replaced or reseated.

Im in the same situation, did you find a solution?
Thanks & cheers!

I contacted ES and the cost to repair was prohibitive. I haven't had the time to try and fix this error as it seems quite complex. What I've found is that the error is more likely to show up if the module is warm. I've since moved it to the edge of the case and, knock on wood, it's been behaving a lot better. I won't be doing anything about this, I think. Since dual mode still works well even though the SRAM error shows up, if the error consistently comes up, I'll just treat the module as a double-disting 4.

Thanks for the fast answer!

The temperature thing is a good hint, I will have an eye on that (although my modules are good vented with some space on the side).
From my side I wasn't able to pinpoint it down to a specific source of error, sometimes it happens more often and sometimes less.
According to my own experience and a search on the web possible sources could be power condition/filtering, IC2 and as you temperature.
What i discovered is that a soft reset (reboot on the module) works much less than a reboot done on the whole rack with waiting a few seconds before power it on again.
While exchanging the RAM would theoretically be possible, it doesn't make sense to me do it as long as we dont know the real reason for the error.
Would be interesting to hear what OS is doing on repair, just changing the IC or do some additional measures on the electrical side aeg adding filtering caps?
Did he go deeper on the issues and a possible solution when you've been in contact with him?
Im only using them in single mode, so dual mode is not an option for me...
Thanks and cheers!

No, I was only referred to Post Modular who does repairs for ES. They sent their pricing information, and I realized considering how complex the module is, any 'normal' fixing of it would be fairly off the table.
