Ah great, I just received a 2nd reply saying that they'll send me the form. If I have to ship back before I get the new board, I probably wont be doing it, except they do overnight. Waiting a week or two will mean at least one difficulty rise (or two) and I'll probably spend the next 2 months mining getting back what I lost during waiting for the board to return. I guess if they send me the label they also pay for the shipping at least.

What would you guys do? Mine away @250ghps@stock or @320ghps@634clock (and hope for firmware that fixes the issue) or send the board to Hashfast?

@Everbody saying I'm lucky:I knew it was a risky investment (even tho all seemed well at HF back then) and therefor I assumed the ~3k$ I paided were gone from start (at least, I was smart enough not to pay in bitcoins) Therefore I didn't engage in the monster thread where everybody let off steam.

On the 2nd of february or so I sent them my first support mail ever (support@hashfast.com), asking for delivery or I would request a refund. 24h later I had the tracking number. Another 2 days later I got a sub perf board, no idea if you guys call that lucky, cause now it looks like I'm basically stuck with it.
When sending the 2nd support mail about the low perf of my board, I included all the information I could possible give them about it, including updating the case with further infos. Not that I think they tried to analyze the problem.

I kept it civil tho, cause I know from first hand experience that the guy/girl sitting at HF support is probably not the one to blame for anything.
And I found it goes along way towards, you know, not pissing the people off who have to decide wheter they go have a smoke and leave for the weekend or just finish that one last friendly formulated case...
