How to ‘Increase/ Max/ Optimize/ Boost’ Nvidia GeForce GT730 4 GB GDDR5 Mining: Overclock| Hashrate| Benchmark | Power Supply (Watt) – In 2014, Nvidia GeForce GT730 video cards were released with 4 GB GDDR5 VRAM with GPU on the Kepler architecture (Compute Capability 3.5, 28-nm process technology). These are video cards that have a certain potential for multi-threaded computing due to the rather large amount of GDDR5 memory.

The similarly named Nvidia GeForce GT730 video cards with DDR3 memory were produced with Fermi chips (Compute Capability 2.0) on a 40nm technological process. They have very poor performance and are not suitable for mining.

This article examines the features of the GeForce GT730 video cards with 4 GB GDDR5 in terms of suitability for mining in modern conditions.

As you can see from the above characteristics, the GeForce GT734 with the Kepler core is not so far behind the 1030 in memory performance, but it is significantly inferior in the core performance. This also affects the hash rate when mining, for example, the GT1030 on the cn-gpu algorithm produces about 265 h / s, and the GT730 – up to 90 h / s.

Computing capabilities of the Nvidia GT730 video card with the GK208 chip (GPU Caps Viewer):

The Nvidia GeForce GT730 video card does not have powerful computing potential, but it has as many as 4 GB of GDDR5 memory, which is very good for video cards of the lower price segment, produced in 2014. It can perform calculations for mining cryptocurrencies on a fairly large number of algorithms, although for this you need to use old versions of miners, or independently compile open source mining programs.

How to Optimize/ Boost: Hashrate of Nvidia GeForce GT730 4 GB GDDR5 during mining

Hashrate of Nvidia GeForce GTX734 video cards on some mining algorithms:

  • cn-gpu (XEQ, RYO, CCX) — 88 h/s (xmrig-nvidia 2.14.5), 72 h/s (xmr-stack 2.10.8),
  • cryptonight_upx/2 (UPX) – 0.3-0.35 kh/s (xmrig 6.16.2);

  • heavyhash (OBTC, PBTC) – 3.8 MH / s (ccminer 2.3.1);
  • kawpow – mining starts in the xmrig 6.16.2 program, but the hash rate is too small, within a few minutes not a single solution is found;
  • lyra2z330 (PYRK, GXX) — 690-710 Kh/s (ccminer 8.21r9-lyra2z330);

Overclocking Nvidia graphics cards with Kepler core can be done in MSI Afterburner (example of overclocking for the core +110 and memory +125 – this overclocking is more suitable for autolykos and ethash, for cn_gpu and equihash the memory frequency can be reduced to reduce heating and save energy):

or in nvidiainspector (this program allows you to more precisely control overclocking and downvolting parameters):

The command line for setting the overclocking parameters of nvidia video cards with the nvidiainspector program (example for the algorithm cngpu):

@echo off

SET VOLT=1000000

SET GPU0=-setMemoryClockOffset:0,0,-50 -setBaseClockOffset:0,0,115 -setFanSpeed:0,%FAN% -setTempTarget:0,0,%TEMP%

"nvidiaInspector.exe" %GPU0%

As you can see from the screenshots above, neither MSI Afterburner nor nvidiainspector shows consumption and fan speeds. The fan on the video card used for the test was connected directly to a 12 volt power supply, so no information about its operation could be displayed.

Power consumption data, apparently, is not displayed due to an unsuitable driver (although officially video cards with Kepler architecture, which include the GeForce 600 and most GeForce 700s, are no longer supported only in Game Ready 496.13 WHQL drivers).

Conclusion

Nvidia GeForce GT730 graphics cards are poorly suited for mining in modern conditions. However, given their memory size, they can perform calculations on many current algorithms. One of the beneficial algorithms for GT730 is cryptonight-gpu. At the end of 2021, this video card can earn as much as 0.25 USD per day, while eating only 0.72 kW))) …
