The 1750 Mhz clock on the webpage is the engine boost clock which is inline
with the settings for your card.
OD_SCLK:
1: 1780Mhz
With respect to the memory clock, The default clock on your board is 900Mhz and
it has a 192 bit interface. GDDR6 sends data on the rising and falling edge of
the wave, so you multiply it by two. Hence:
OD_MCLK:
1: 900MHz
900 Mhz * 192 bit * 2 = 345,600 Mbps = 337.5 Gbps
Which is right in line with the bandwidth for your card.
