Testing Methodology

Like the other memory reviews we have done in the past, we will only concentrate on testing the overclockability of the modules since there are no reliable memory benchmarks.

Unlike the testing we have done in the past, we are testing all three timings supported by the modules - 2-2-2-5, 2.5-3-3-7 and 3-4-4-8.

For those who are not familiar with memory timings, the first number refers to the CAS Latency, the second number to the RAS-to-CAS Delay (tRCD), the third to the Row Precharge Delay (tRP), and the final number refers to the Row Active Delay (tRAS). For more information on these timings, please consult our BIOS Optimization Guide.

We also tested the memory modules at the voltage of 2.65V (measured voltage of 2.68V) as well as an increased voltage of 2.85V (measured voltage of 2.88V). To check stability at overclocked speeds, we tested the memory modules with Memtest86+ v1.50.

There are no official timings for these modules, but PDP Systems has stated that they will do 200MHz at 2-2-2-5. So, we'll see how far they can go!

Almost all TCCD modules will be able to hit 200MHz at tight timings easily. But as they scale higher and higher, it is virtually impossible to make them run with any resemblance of stability, despite feeding them more juice. Is Patriot memory any different?

Well, unfortunately it's a 'no', but it certainly overclocks slightly better than the best TCCDs we have tested! 218MHz is 9% faster than the stock speed. This is actually the best TCCD modules we have tested! But remember, while it's better than the others we have tested, it's only better by a small margin...

As we expected, increasing VDIMM did not make any difference. The modules remained stubbornly stuck at 218MHz.
