We will not see any amd radeon r9 nano with overclock

AMD has banned graphics card manufacturers from upwardly altering the operating frequencies of the Radeon R9 Nano, plus we won't see custom heatsink versions for at least 3 months.
This means that initially we will only see cards with a reference design in which manufacturers can only modify the stickers to differentiate their product. Once three months have passed from your arrival date (September 10) we will see cards with custom heatsinks although all of them must maintain the dimensions of the Mini ITX standard and cannot have a TDP greater than 175W.
This decision could be mainly due to the little difference that exists between the Radeon R9 Nano and the Radeon R9 Fury X, both cards are identical except for a lower working frequency in the Nano and a TDP limited to 175W also in the Nano by the presence of a single 6-pin power connector. This ensures that the Nano will always be inferior to the Fury X in performance and will not harm sales of its older sister.
