jaybee,

Basically the PandaCoin crash is not a "technical" crash... rather it's the coin itself "imploded" because the founders and developers starts to dump their premined coins and pointing fingers at each other.... Did some reading on their forum, it was pretty ugly....  Unfortunately for me, I am stuck on port 3385 until Monday because I am out on biz trip....  Kind of a "black humor" on myself watching the circus act on their forum while my mining rig faithfully and relentlessly mining the coin that basically has been declared dead....

To also address your issue with vertminer, If you have 700k on 270x and all HW error, very likely you forgot to change the "scrypt" to "nscrypt"...  you should look into the readme in vertminer.... When properly setup to n-scrypt, your 270x shouldn't output more than 300kh/s...  and you shouldn't worry, because it will apply to EVERYONE mining n-scrypt...

Back to Pandacoin....  despite the recent jaw-dropping development of events, kind of amazing that it's still maintaining the current "score" and not completely dead yet....  On the other hand, strange that VTC is in the same range score wise... Anybody with insights there?
