Overclocking, Temperatures & Noise

Overclocking using PrecisionX1, temperatures & noise 

The RTX 2080 and RTX 2080 Ti are both very quiet cards even when overclocked.  We could not hear either card over the fans of our system even when they ramp up.  We will spend more time with overclocking in our follow up review, but we did manage to overclock both of our RTXes using NVIDIA’s new automatic scanner in the form of PrecisionX1 which is not yet available to the public.

The above image shows the RTX 2080 Ti at idle on the desktop.  The voltage seems to be a bit high with or without temperature and power targets set to maximum.  We benchmark our video cards with these targets at maximum to unleash the cards full performance potential at stock clocks.

We used NVIDIA’s new scanner and it found it to be quite accurate compared with the scanner that released with Pascal.  To find the best automatic overclock, click on the Scan button and wait for about 20 minutes. You can also test the stability of your overclock by using the Test button.PrecisionX1 decided that 1950 to 1980 MHz was the maximum safe overclock, set it automatically, and gave us a score of 193.

We tried out own manual overclock and were able to add 200 MHz to the core to peg the clocks mostly at 2000 MHz after we pushed the voltage slider to maximum with peak Boost around 2050 MHz.  We also were able to add +800 MHz to the RTX 2080 Ti’s memory clocks(!)

Our preliminary RTX 2080 Ti overclock is +180 MHz offset to the core and +800 MHz to the memory.  Our final overclock will be explored in Turing, Part 2, later this week.  In the meantime, we tested 10 games at 4K resolution to see if our overclock has made any performance difference.

We see several games where an overclock may help to improve a game’s fluidity at 4K.  It appears from our very limited time with RTX 2080 Ti that overclocking is good and similar to Pascal overclocking, but it appears that a steady 2000 MHz is close to the limit for Turing with peak Boost around 2050 MHz.  We also like NVIDIA’s new scanner, and EVGA’s new PrecisionX1 is much more stable than when it released for Pascal.

We also used PrecisionX1 to overclock the RTX 2080 with similar good results.  It gave us a score of 115 and a top boost of 2025-2040 MHz.  

Our preliminary overclock for the RTX 2080 is +115 MHz offset to the core and +700 MHz to the memory.  Temperatures for the RTX 2080 remained cool in the 70s C range although the RTX 2080 Ti would reach into the low-80s C under maximum load and during the highest overclock in the PrecisionX1 scan.  The noise from the RTX cooling fans never became noticeable over the other PC case fans.

Let’s check out performance after we look at our test configuration on the next page.
