One of the fastest and simplest ways to improve your computer’s overall efficiency is to update your memory subsystem. In certain cases, it can take less than five minutes to uninstall your old memory and switch in a new kit that is quicker and/or more efficient. It’s no surprise, though, that this is always one of the first improvements to remember when sprucing up an ageing device. What Russian modder VIK-on has done in his new video set, though, is far beyond a mere memory update.

The hardware tweaker took the Palit-branded GeForce RTX 3070, deleted the 1GB GDDR6 memory modules (K4Z803256C-HC14) and replaced them with 2GB GDDR6 versions (K4ZAF3258M-HC14), essentially doubling the memory of the card to 16GB.


If that wasn’t enough of a challenge, VIK-on even had to adjust some of the resistor settings to trick the card into realising that it now has twice as much memory on the tap.

Unfortunately, the questions remained. Similar to what happened when the mod was tested on the GeForce RTX 2070, the card will crash after an extreme workload. This is where YouTuber subscribers came up with a possible alternative.


As it turns out, the use of the EVGA Precision X1 tuning tools to lock the card’s frequency has corrected the problem, enabling the modder to complete the benchmarking in 3DMark Time Spy and Unigine Superposition – 8K Optimized. The outcomes of these evaluations are in line with what you’d predict, showing that the update was a success.
