Why can't overclock Gigabyte gt 730 1gb ddr5?

Question

Iron

Good day to all!
I recently purchased a budget video card Gigabyte gt 730 1gb ddr5. Decided to try and speed it up a bit. I used MSI software: MSI Afterburner for overclocking and MSI Kombustor 3 for stress tests. It was possible to achieve acceptable results without artifacts and driver crashes. During the stress test, the card was loaded at 85-90%. Stress tests were carried out for 5 - 15 minutes. after each MHz increase phase. The final test at maximum load in MSI Kombustor gave a positive result. I decided to check the performance in Fallout 3 on ultra at a resolution of 1680\1050 (native monitor resolution). I chose the most "heavy" place on the map, with the maximum drawing range and a large number of objects. And then the map began to fall. Windows returns messages that the driver has fallen and has been restored. I can not understand, why in stress tests with max load there were no falls? and in fallout 3 there were crashes every time the game started. With a difference of 2 - 3 sec. I want to note that the card without overclocking gives excellent FPS on ultra in Fallout 3. Everything is sad with overclocking .... Guys, maybe this 730 chip is not designed for overclocking? Or "locked" in some way by the manufacturer? The most interesting thing is that some people manage to overclock, but they only give information on stress tests ... I also have everything buzzing in them at optimal values ​​\u200b\u200b..... And one more thing ... According to my observation, the increase in fps in this card gives only overclocking of the core, but not memory... The increase in performance during overclocking of the memory is so meager that I did not notice the difference.. And the heat dissipation does not increase during overclocking of the memory, it feels like the modules simply do not respond to overclocking....

Answer 1

Because. And in general, this is the whole answer. Yes seriously. Find the definition of overclocking and read carefully. For overclocking - it may be successful, it may not be very good, or it may be a failure. Something is chasing, something is not.

Answer 2

A lot of nuances of overclocking. In short, then! you "at random" grope for the upper limits of the work of the stock card, and try to operate in this mode with a serious load in games, so you can bury it very quickly. For more or less correct overclocking, you must at least remove the radiator and see how well the power is cooled! video chip. By increasing the frequency of the GPU and video memory, the consumption also grows, the power transistors heat up more. If we take into account that in 80% of cards from the store without modifications, the power supply is not cooled properly in principle and under serious loads the transistors heat up to almost extreme temperatures (over 90 degrees), in general, it will only burn out)) And all the cards are chasing) The better the cooling , the more stable operation can be achieved at higher frequencies.
