How can I know what batch I have? Stupid question but I can't find it nowhere.. I bought it second hand.
B8 and so on has a sticker on it that says S3+. I'm really unsure prior to b8, it would be nice to know as well.
S3+, which means S3 B8 and the following batches, has a faster hashing speed, 453Gh/s than the one from the previous batches, which hash at rated 440Gh/s.
