Overclocking the Platinum XTC memory

PCSTATS Test Methodology: On AMD socket AM2 test systems, we're only interested in seeing how high we can go with the DDR-2 memory running 1:1, as running with other dividers puts the overclocking bottleneck elsewhere and not with the system memory. The DDR2 RAM latency must run at its lowest possible setting, as quick access is more important to the CPU design. Just for arguments sake, we will also be conducting overclocking tests to see how high the memory will go with lax timings (5-5-5-15), although we will only benchmark the system with the tight memory timings mentioned above. Let's get started!

Overclocking Results:
4-4-3-15 5-5-5-15
memory speed: 1096 MHz 1104 MHz

If you're new to Overclocking and not sure what to do, check out these two excellent Guides for some pointers:

Overclocking the Videocard

Overclocking has been OCZ's target specialty since the beginning - heck it is OverClockerZ - and we've had quite a bit of luck with OCZ memory modules in the past. Before the overclocking session started though, the AMD Athlon64 FX-62 CPU clock multiplier was lowered to 10x. This ensures the processor will not max out before the PC2-7200 Platinum XTC does.

With the memory voltage kept at 2.1V, the memory frequency was increased in 4-6 MHz intervals from a starting point of 200 MHz. The chrome heatspreaders were quite warm to the touch, but stability maintained for quite a while... sometimes overclocking takes a lot of patience. Of course, since these modules are EPP compatible, we could have just enabled that on our nForce 590SLI motherboard - but what fun would that be?

The OCZ PC2-7200 Platinum XTC memory kit overclocked to a nice round 1000 MHz before the system started to show cracks. Increasing the voltage to 2.2V was necessary, and a few more tries later that was adjusted to 2.3V.

With 2.3V the OCZ PC2-7200 memory reached a maximum overclocked speed of 1096 MHz, with the all important low CAS latency timings of 4-4-3-15. Settings faster than this were possible, but the system randomly BSOD'd while running benchmarks. Still, I've gotta say that an overclock to 1096MHz from memory that's only 'officially' rated to run at 900 MHz is pretty sweet indeed!

Loosening up the memory timings to 5-5-5-15 allowed the OCZ PC2-7200 Platinum XTC memory to balloon up to 1104 MHz before totally fizzling out. In this case it was the motherboard that was becoming the bottleneck I suspect.

Prelude to Benchmarks

The details of how the OCZ PC2-7200 Platinum XTC memory test system was configured for benchmarking, including the specific hardware, software drivers, operating system and benchmark versions are indicated below. In the second column are the general specs for the reference platforms this pair of PC2-7200 DDR-2 memory is to be compared against. Please take a moment to look over PCSTATS test system configurations before moving on to the individual benchmark results.

At stock speeds the OCZ PC2-7200 Platinum SLI memory performs on par with the competition, it should after all the speed and timings are identical. Overclocking does boost performance slightly, but at 274 MHz motherboard clock speed the CPU is only running at 2.74 GHz.
