I will be benchmarking the Titanium CL3 modules and comparing results to another pair of OCZ's Platinum series running at the reference 5-5-5-15 spec. I tried to keep the CPU speed as consistent as possible so that the results depict the difference in memory settings only. The four test sets chosen to compare are:

First up is SiSoft Sandra XIIc, Memory Bandwidth and Memory Latency benchmarks.

Tighter timings do help out a bit, but on the bandwidth test Mhz seems to be key. Timings do make a big difference on the latency test, but still not quite enough to beat out the high speed.

Next we'll look at Everest Home Edition 2.2

On both the read and write tests, the CAS3 overclocked comes out on top, and just barely squeaks by the top speed on the latency test as well.

Now let's look at some results from RightMark's Memory Analyzer, using the STREAM memory benchmark standard.

Here we see a repeat of the SiSoft tests, with the CAS5 top speed overclock topping the charts.

Although PCMark05 also takes into account CPU and overall system speed, memory does play a big part.

On the overall system score, the low latency overclock wins by a wide margin, no doubt helped in part by its higher CPU clock speed. Comparing just the memory latency results themselves, we see the CAS3 and higher speed CAS5 evenly matched.

Finally let's wrap up with SuperPI.

A faster CPU is more important when crunching numbers, but here we see that both memory speed and timings play a role as well.

On to final conclusion.
