AL422 speed limits

Hello. I use a Fifo IC AL422B with a 1 MHz write clock and a 625 kHz read clock. I just discovered that 1 MHz is the low speed limit for the clocks. I can speed up the write clock to 2 MHz but unfortunately I can't change read clock speed. As these clocks ( or at least one of them) are used for refresh cycles, do you think that increasing write speed will be sufficient to insure a proper way of work ?

The datasheet says it is self-refreshing, so that doesn't look like an issue:
