Enhanced Performance Results (Cont.)

To be able to compare the outcome of the change on the memory timings we will use the Everest Ultimate Edition software suite from Lavalys once again for compiling the performance results. The Everest Ultimate Edition has several benchmark items that can be executed to get to the bottom of impact of the memory timings on the actual performance of the G.Skill Low Latency PC2-6400 Edition memory. This means that we will adapt the memory latency settings manually as advertised by the manufacturer, so these will be reduced to 4-4-3-5. We will run the same benchmarks and follow a similar approach to compare a bit the results.

We are using the memory as before at 800MHz memory speed, but with adjusted timings. The memory latencies used have been decreased to the bare minimum which gave us a 4-4-3-5 as outcome. We will now check how the timings will influence the performance of the Low Latency Edition dual channel memory modules. The latency is set as advised by G.Skill on their Low Latency high performance version, which should provide the optimal bandwidth and corresponding performance. In the end this is what each buyer of these sticks should do to enjoy the real and true performance for which these G.Skill modules were designed.

Memory Read Results

Having optimized the memory timings we get immediately an increase of performance delivered by the Low Latency Edition DDR2-800 memory. These G.Skill memory sticks put down a score of 7391MB/s which is a significant increase of about 190MB/s. This confirms that the latency settings do matter when looking for the ultimate speed demons. With these high performance edition sticks G.Skill has raised the bar once again in memory bandwidth and performance. The sticks will do even better when we would have a better processor to feed the information, so going for a 3.0GHz CPU and more will do well to these G.Skill memory modules.

Memory Write Results

Again we see impressive scores with the write sequence; here we get a solid 4804MB/s of constant write allocations to the G.Skill Low Latency PC2-6400 Edition ram modules. Looking back at the default results we spot a limited boost, the bandwidth going up by about 40MB/s isn't really that much to write home about. This is certainly a disappointment somehow, but since the write performance had reached already a quite high level, it natural that it could have hit the limit of the memory chips. But once again an excellent result put down by the Low Latency memory sticks.

Memory Copy Results

Moving on we have the Copy results which resulted in a score of 5325MB/s which is a boost of about 200MB/s over the performance reported at 800MHz with the timings set by the SPD. Once again a quite significant boost in performance and the stability was never compromised. Running smooth and fast, just the way we want. During the Memory Copy run the G.Skill Low Latency Edition memory modules are actually the fastest we have seen so far on all our benchmark runs, when looking at the DDR2-800 memory kits. Of course these are just running a bit slower compared to the 1000MHz modules, but coming very close.

Memory Latency Results

On the latency results we also see an improvement, by having dropped to 60.1ns while this was only 64.3ns with the default timings. This is quite okay but isn't that significant in the overall performance picture of the memory results. However the lower the latency means in generally the faster the memory can act and refresh the content and date stored within the memory chips. And faster refresh means that these Low Latency sticks are truly hardcore performance modules. So once again a good improvement with the optimized latency settings as advertised by G.Skill.

After adjusting the memory timings towards the DDR2-800 levels, well actually lowering them down to the minimum of 4-4-3-5, the G.Skill Low Latency Edition shows off some outstanding performance. The performance is up there with the high performance DDR2-800 modules from Corsair and OCZ. So by going for the G.Skill Low Latency PC2-6400 Edition ram modules you get excellent performance and a bit more. Great job by G.Skill on delivering some excellent high performance memory modules, with very low latency timings which we haven't seen yet that much coming from other manufacturers. So well done G.Skill!
