I bought 4 -NEW- Sapphire RX 460 unboxed from a sealed box...
Strange then, that someone modified them at factory...still good rate, 3 out of 4
460s transformed into 560s is OK in my book
But why did you say 560s in your original post?
Yes, I said Sapphire RX 560.
I paid for 16 CU

But in previous post you said
"I bought 4 -NEW- Sapphire RX 460 unboxed from a sealed box... Sad "
Whatever...460s have 14 CUs and 560s have 16 CUs...draw your conclusions form that fact
OPS, I took a mistake: I would have said "I bought 4 -NEW- Sapphire RX
560 unboxed from a sealed box... Sad "
The card are labelled as 560, "five" is the first digit
So maybe 1 card is bad
EDIT:
there are 2 types of RX 560 card from sapphire:
11267-00 --> 90W edition
11267-01 --> 45W edition
Maybe the SAD edition (the 11267-01) has only 14 compute units...
