Introducing the new EVGA GTX 560 Ti 448 Core FTW

Overclocking & Temperatures

 

Overclocking

Overclocking the EVGA GTX 560 Ti beyond the stock overclock was easy.  As usual, we are not looking for the ultimate overvolted overclock with our VGA fan screaming along at 100%.  We always test with our card at stock voltage and the stock fan profile so that our reader may have a good idea of midrange overclocking.

We reached 855MHz on the core and upped the memory +50Hz to 2000MHz.  That 855Mhz is +58MHz over EVGA’s own 65Hz overclock and +123MHz over the stock Nvidia reference clocks.  On the other hand, the +100MHz total memory boost is quite conservative.  We could have gone much higher on the core and on the memory if we were willing to turn up the fan speeds.  As it was, high core temps were the sole limiting factor on our overclock as far as we could see.

We always use EVGA’s Precision overclocking tool which recently added integrated GPU voltage adjustments.  Here are its features from EVGA’s website:

Features:

  • NEW! Now with integrated GPU Voltage Tuner (BETA)!
  • Independent or Synchronous control for fan and clock settings in a multi-GPU system
  • Allows up to 10 profiles, and ability to assign hotkeys to these profiles to allow in-game
  • Ability to view temperatures in the system tray
  • Fan profiling system
  • Core/Shader Clock Link/Unlink capability
  • Fan Speed manual or auto adjustment
  • Real-Time on-screen display support for ingame temp, framerate, and clock monitoring
  • Logitech Keyboard LCD Display support
  • In-app temp/clockspeed monitoring of GPU’s
  • Information button shows device, driver, memory size, BIOS Revision and SLI mode
  • Ability to choose different skins, and make your own!
  • Now you can save screenshots from your favorite games!

Temperature

Our ambient (room temperatures) were quite warm – 80F – so as to approximate a warm Summer day. Be aware that we used our Thermaltake Element G case which has excellent airflow for an oversized midtower.  The GTX 560 Ti runs quite cool at the EVGA factory overclock, in the low to mid-40s C even under load.  However, once the core speed increased, so did the temperatures until we were idling in the low 60s when we hit 850MHz on the core and would easily rise into the 80sC; 100C shut down the GPU – even if it just peaked there for an instant.  860MHz was not attainable without increasing the VGA fan speed, so we settled on a stable 855MHz and kept an eye on our temperatures.

Read on as we see what effect increasing core speed has on the EVGA GTX 560 Ti 448 core FTW – from the reference speed, to EVGA’s overclock to our own.  The performance summary charts are up next.

    Great review!!!!!

    I love it. set the page drop down to “8 view all” and your set! No bull, straight down the line. with your charts its very easy to compare these cards. the 3d was a treat too.

    great job

    Thanks for every other excellent post The place else could anyone get that kind of info in such an ideal way of writing? I have a presentation subsequent week, and I’m at the search for such info
