Not going to read that guide so you need to compare with original article i linked above yourself if you are unsure how to do it. It is very easy and straight forward. All you do is extract your bios (oc or silent), load that into MPTs and tweak the values you want. You then click on the write to registry button. No hand hussling in the registry involved. You can save your chosen modifications so you can easily load that file and reapply if need be. Not totally sure whether this needs to be reapplied after a driver update, but i don't think so. And you would notive anyway as soon as you look into Wattman.
BUT: in the end, when doing this on a 5700 non XT model, this is more helpful if you try to enhance its strength. From my experience; the non XT models don't have uber-duper chips and trying to squeece out 5-8% more performance comes a fairly high cost energy -and heat-wise. Even the XT models struggle here and i really feel you are getting a worse deal when pushing a non XT card. You can do it, and it is fun playing with this, but in the end you are likely running the card far away from its sweet-spot. 90% performance of a good XT card cool and quiet at 145-160 watts if you undervolt, or maybe 95% hot and louder with 180-200 with spike up to 220 watts. One can get lucky with the silicon so i guess playing around with this is a fun passtime.
But; the MPT allow at least for activating the Zero Fan mode inside Wattman. That alone is worth it, and this cannot be claimed to be necessarily the case when flashing a bios.
