Many of us have modded the A4000 card with the Palit StormX or PNY 3060 coolers to make our own tiny "A4000 Aero" gpus.
The OC'd A4000 performs slightly better than the 3060 Ti, but draws much less power. It's power starved.
Shunt modding is the process of adding a resistor to the card in order to increase it's power draw. It was very popular with the A2000.
It's well known that the A4000 is power-limited 3070Ti card with a smaller PCB. Techspot does a great job breaking down the differences between them here.
Some relevant quotes ...
Previously, I didn't think shunt modding the the A4000 would do much because it only has a 6-pin PCIe plug, but youtubuer Wiltshire Tutorials showed that the 8-pin traces on the A4000 are still active and you CAN solder on an 8-pin and it will work!
Does anyone have any ideas or suggestions on how to shunt mod the A4000? With the 8-pin power plug it may be possible to restore that 3070Ti performance and keep the 3060 Aero size.
I've seen a some whispers on reddit that it is possible, but I can't find any serious evidence that anyone has ever shunt modded the A4000. SFF crew, help me out. Do you think it's possible to shunt mod the A4000?

In short, the RTX A4000 uses the same GA104 silicon as the RTX 3070 Ti, meaning it has 6144 CUDA cores, 192 TAUs and 96 ROPs
On that note, the A4000 was fed just 770 millivolts under load whereas the RTX 3070 Ti was fed 1040 millivolts, so that's a substantial difference in voltage there, and it's what enables the 3070 Ti to run at much higher frequencies, but it also blows out power consumption, as does the use of GDDR6X memory. Unfortunately, Nvidia doesn't allow you to tinker with the voltage of the A4000, or at least I haven't worked out how to yet.
