MemShift Problem on Rx 470 Nitro+ 8gb

[Crypto_Future]

Hello I did a memshift on Rx 470 Nitro+ 8gb which defaults on 2000Mhz.
I used 1500 straps, and now the card is not stable on 2000Mhz.
It is however on 1900.
My hashes increased from 24 to 28.
the question is:
1)Should I decrease VRAM speed on Bios?
2)Should I use straps from 1625?
3) Should I increase Vram Voltage?

1) No
2) No
3) No

Use 1750 straps

What memory brand you have?
Better to use performance timings. If you want it or help with bios, PM me.
