so mining xmr, (im noob pretty much), only have mined vtc with their ocm for a year and now just getting into more traditional mining effort/set up

so jumping into it i am only getting like 540hash with these settings 1200 core, 900 mv and 1100mhz on memory with 925 mvthese were the settings i found in some other thread of someone saying they were getting upwards of 2200 hashes

im using teamredrider - and just confused why such low hashing.. kinda noob at this so figured id come here could someone lend hand as to why/where/what i am falling down on this hash rate with xmr?

my setup is a vega 64, on msi b450 tomahawk, ryzen 5 2600x, 750w gold PS.
using teamredrider

pls thx
