Phase 3 - The final run - everything overclocked
Phase 3 - The final run - everything overclocked
Aaah, welcome to phase three - The final run. We established a stable enough, overclocked CPU and memory clocked at the maximum we can gain from liquid cooling. We have setup Quad-SLI and have been able to finish and break a (personal) record with 3DMark Vantage.
With some added cooling and the GPU FANs now running at 100% we tried to take things one step further, overclocking the GPUs. Now this is like opening up a can of worms really as each and every graphics card of the four can react differently towards overclocking.
We installed MSI AfterBurner which allows us to do whatever we need to do. Here's what we did:
-
GPU Voltage increase to 1.2 Volts
-
GPU Core/Shader (1:2) increased towards 772 MHz core / 1543 MHz shaders
-
Memory -- we left it as is for now
With the neighbors wondering what all that noise is so late in the evening we finalized another 3DMark Vantage run successfully. Quite honestly the GPU overclock was a little bit disappointing in terms of added performance as we expected more, but still we retrieved the following scores:
-
42967 P-Score
-
43291 GPU-Score
-
42053 CPU score
Now let's put that into some perspective shall we ? Here's an overview of 3Dmark Vantage with a wide variety of graphics cards (clocked at default of course).

So here we have a wide scope of cards, I included multi-GPU setups like 2-way SLI and crossfire for the latest GPUs from ATI and NVIDIA. Highlighted are a single GTX 480 and then our run in quad-SLI. Crazy stuff really, but is scales reasonably well.
