Extreme Performance & Overclocking

Now we just figured to go one step further and check what more is possible with the Low Latency Edition series from G.Skill, because maybe there is more left in this memory than we might think. This will actually be done in two ways, either by overclocking the memory speed or by overclocking the Intel Core 2 Duo processor. Both should show an increase in performance, so we will check what the exact impact is for these Low Latency Edition memory sticks. This time we will be using SiSoftware Sandra to provide us the memory bandwidth raw power indication. We did quite some benchmarks, and started each of these at the nominal 800MHz memory clock speed.

Memory Bandwidth (PC2-6400 800MHz - E6700 2.40GHz - 5-5-5-15)

Memory Bandwidth (PC2-7200 900MHz - E6700 2.70GHz - 5-5-5-15)

Memory Bandwidth (PC2-7600 950MHz - E6700 2.85GHz - 5-5-5-15)

We are actually taking a dual approach as we are both overclocking the G.Skill Low Latency Edition memory chips as well as our Intel Core 2 Duo E6700 processor. Starting at the slightly lower settings of 2.40GHz for the Core 2 Duo CPU and 800MHz memory clock speed, we can see that by increasing the bus speed feeding that the bandwidth is showing a nice boost as well. This means however that when we increase the bus speed we get a positive effect on the overclocking of both the CPU and DDR2 memory. We want to point out that we set the memory voltage a bit higher as well, and by doing so it reached its limit of 950MHz at 2.1V, which is within the voltage operating range specified by G.Skill.

Our second overclocking attempt already starts a bit further. We configured our system this way that we could once again start at 800MHz memory speed but with the Core 2 Duo default clocked at 2.66GHz. We will now repeat the same logic as above and see what that means in raw performance of the G.Skill Low Latency Edition PC2-6400 dual channel memory kit. By increasing the bus speed, we will increase both the CPU and memory speed equally and find out the maximum performance of these high performance memory modules. And by doing so we are able to provide you all with a much better view on the actual performance that you can expect from these G.Skill memory sticks.

Memory Bandwidth (PC2-6400 800MHz - E6700 2.66GHz - 5-5-5-15)

Memory Bandwidth (PC2-7200 900MHz - E6700 3.00GHz - 5-5-5-15)

Memory Bandwidth (PC2-7600 950MHz - E6700 3.16GHz - 5-5-5-15)

Yeah these G.Skill Low Latency Edition sticks keep amazing us with their top notch performance. Having increased the memory speed to 950MHz and also upped the Core 2 Duo E6700 to 3.16GHz the bandwidth boost is just unbelievable. We notice a significant gain of about 100MB/s from our default configuration to our heavy overclocked system. These memory sticks just blew us away. And if you are really looking for high performance DDR2 memory, then you should look any further...
