Good Day

Needs to replace vram chips on a gtx1070. The original chips are k4g80325fb-hc28..

The replacement chips i have is k4g80328fb-hc25... The last two numbers hc28 and hc25 are different. Does anyone know what they mean and are they cross compatible..??

As per samsung specs both are the same. The only difference i dont understand is these two last digits..

Both vrams are gddr5..

Thanks
