Radeon RX 480 Memory Voltage Mod from Buildzoid, Shot in First Person

Our man Buildzoid certainly knows a thing or two about volt modding graphics cards. His most recent foray involves volt modding the memory of his Radeon R480 card. As usual Buildzoid offers a technical overview of the job with tons of useful tips and tricks along the way. Perhaps most interestingly however is the fact that the video is actually recorded from a first person perspective, so you have a pretty accurate view of virtually everything that he sees.

The first step in the process is actually identifying the voltage controller for the card?s memory. It can be found on the back of the card, on the opposite side of the memory?s VRM which supplies 1.5v to all the memory chips. After identifying the high and low-side FETs, Buildzoid points out the fixed frequency 600KHz, single phase chip which integrates a driver with a synchronous buck controller. The chip has voltage sensing built-in to it, making it the target chip for the volt mod.

The actual surgery involves attaching a wire to the sixth pin of the voltage controller chip. The video goes into some pretty serious depth regarding the actual procedure of soldering the wires, applying the solder and more. A great video for anyone who has little experience of hardware modding.

Check out the video in full on the Actually Overclocking YouTube channel.

That was cool thanks for sharing sdougal and buildzoid. The first person was cool but the auto focus was a little frustrating. But you are entertaining to watch and listen to.

I ended up staying up until 6am watching some of your streams after watching this.

Yeah the webcam is a little dumb about focusing on things. This was just a pilot and might get a better camera for things like this in the future because it makes it so much easier for me to show what I'm doing.

I really liked it. I guess I meant it was frustrating for you. But the idea was great. I watched your birthday stream after, something about you makes it hard to turn off. It's also fun to see how other people do there benching.

First person is quite a nice approach. Awesome channel, by the way
