Galaxy GTX 465 in SLI Overclocked w/ Voltage Adjustment

Using ol' faithful MSI Afterburner to do our overclocking today, we had set the bar high. When we tested the MSI GTX 465 Twin Frozr II we achieved some pretty awe inspiring numbers. We ended up with a core clock of 860MHz and Shader clock of 1720MHz which are no doubt massive increases from the default 608MHz and 1215MHz setup.

Memory also went through the roof from 3208MHz QDR to 4100MHz QDR. We didn't expect to get the same numbers from the Galaxy setup for the simple reason that when we throw two cards into the mix heat becomes something you have to worry about.

Last time we looked at the Galaxy GTX 465 in SLI we managed to achieve a core of 700MHz, Shader clock of 1400MHz and memory clock of 3600MHz QDR. While we didn't hope for much more on the memory, we had hoped to get the core closer to the 800MHz mark.

It became clear, and quickly that my expectations were too low. What we ended up with were some very fast clock speeds.

The core finished up at 830MHz which is over 200MHz faster than the stock core on both cards. That in turn pushed the Shader clock up over 400MHz to 1660MHz QDR and the memory decided to wake up and run at a very rounded 4000MHz QDR.

These are some big numbers and should bring with them some big performance. Let's get stuck into the benchmarks to see exactly what is going on with the cards.
