Which ASIC chip should I choose for my S17+? BM1397AG or BM1397AH

BM1397AG or BM1397AH I'm looking to fix some chips on my hashboard and I need to figure out which ones to get. Does it even make a difference which one I buy if they both are compatible with the S17+?

Both of them support s17+ but I suggest that replace only the same chip model there might be differences on performance and temp.

I recommend you to buy the BM1397AG chip, because the original chip of the S17+ hash board is the BM1397AG. In fact, most of the BM1397 in the 17 series are universal, but if you can find the original model, try to buy the same one. Because different serial numbers represent different working voltages.
