I'm not sure which one is showing me the correct Core and Memory speed, its really confusing me.

on the msi the boost is active what speed you have if it is set to basic .

i don't now if you missed out words or the lack of punctuation, but i have no idea what that means.

Afterburner is correct I would gather. GPU is clearly under load, but not hot, and you have set an offset. 1300Mhz + 186Mhz = 1486Mhz, the crystal in the card isn't exactly 100Mhz so it is getting up to 1489Mhz.

If you are confused on the memory speed, remember that it is GDDR (Graphics Double Data Rate) So the memory communicates on both the leading and trailing edge of its pulses. MSI Afterburner is showing you effective memory speeds, GPU-Z is showing you actual frequency. Double that number and it matches.

GPU-Z is likely reporting the boost values loaded into the card at he factory. MSI Afterburner is overriding that default via software, which GPU-Z might not be picking up.
