Making unobtainium graphics cards much more unobtainable, [VIK-on] has swapped out the RAM chips on an Nvidia RTX 3070. This makes it the only 3070 the world to deal with 16 GB.
If this sounds familiar, it’s due to the fact that he tried the same trick with the RTX 2070 back in January Couldn’t get it working. When he initially published the video showing the process of desoldering the 3070’s 8 Hynix 1 GB memory chips and replacing them with eight Samsung 2 GB chips he hit the very same wall– the card would boot and identify the increased RAM, but was unsteady and would eventually crash. Useful tips from his viewers led him to use an EVGA setup GUI to lock the operating frequency which repaired the problem. Further troubleshooting (YouTube comment in Russian and maker translation of it) revealed that the “max efficiency mode” setting in the Nvidia tool is likewise an option to support performance.
The new memory chips do not self-report their specifications to the configuration tool. Instead, a set of 3 resistors are used to digitally identify which hardware is present. The problem was that [VIK-on] had no concept which resistors and what the different configurations accomplished. It seems like you can simply start changing absolutely no Ohm resistors around to see the impact in the GUI, as they set up both the brand name of memory and the size offered. The truth that this board is not presently sold with a 16 GB alternative, yet the setup tool has settings for it when the resistors are properly set up is kismet.
Did it make a substantial distinction? That’s challenging to state. He’s running some standards in the video, both Unigine 2 SuperPosition and 3DMark Time Spy results are revealed. Nevertheless, we didn’t see any trial run prior to the chip swap. This would have been the secret to characterizing the real impact of the hack. That stated, reworking these with a portable hot air station, and working your method through the resistor setup is darn remarkable no matter what the efficiency bump winds up being.
When he first published the video revealing the process of desoldering the 3070’s eight Hynix 1 GB memory chips and replacing them with eight Samsung 2 GB chips he struck the very same wall– the card would boot and detect the increased RAM, however was unsteady and would eventually crash. Handy tips from his audiences led him to use an EVGA configuration GUI to lock the operating frequency which repaired the issue. Rather, a set of 3 resistors are used to electronically recognize which hardware is present. It sounds like you can just begin changing absolutely no Ohm resistors around to see the impact in the GUI, as they configure both the brand of memory and the size readily available. We didn’t see any tests run prior to the chip swap.
