Your number looks great, but Im not on those types of 5700xt.
5700 should be able to do about 57mh without the memory timings, so I don't think 52 is a "great looking number"
please share the setting of a 5700 able to do 57mh without the memory timings or with the memory timings
1) you flash bios mod ( populate higher mem frequencies from the strap of 1500)
2) set volts to 788-810mv, ~1360 core and 1860 mem
