Here are a few benchmarks of RAM performance. It’s difficult
to gauge how much memory bandwidth affects performance, as keeping the CPU speed
constant is not possible. My P4 2.4GHz is locked, so I’m unable to play
around with the multiplier and FSB to get similar clock speeds. The only method
I had was to increase the CPU:DDR ratio from 2.5x to 2.6x, giving a small boost
in memory speed to 354MHz while keeping the CPU constant.
For testing increased memory bandwidth, I simply increased
the FSB required levels.
|SiSoftware Sandra 2002
SiSoftware Sandra 2002 has a memory benchmark to test synthetic
memory bandwidth. In both Integer and Float tests, the memory reaches around
2500MB/s, not far off from the theoretical max of 2700MB/s. Overclocking the
memory gives a nice linear increase. The farthest I went with the RAM is 410MHz,
giving 3100MB/s—pretty good for PC2700 RAM.
Edit: I used Memtest86 for
2 hours to verify that it was stable.
Cachemem is another memory benchmark. It provides more realistic
results than SiSoftware Sandra but shows the same trend.
The two games I tested were Unreal Tournament and Quake 3 Arena.
These results aren’t as interesting, as I couldn’t increase memory
speeds much. We do see a gain of 4-6 frames per second with a 20MHz increase
in RAM speed, with higher FPS being better as always.
OCZ DDR PC-2700 Rev 3.2 is a great set of RAM. It has everything
that you can demand from memory: low memory timings, great looks (for those shopping
in the looks department) and exceptional performance. It’s the best RAM
I’ve ever used.
Though only rated at 333MHz, it was able to reach all the way up
to 410MHz with a voltage increase. That’s a 24% increase in memory speed.
Performance goes up across the board with no detrimental effects. It is very
capable RAM that will benefit any motherboard chipset with memory tuning capability.
The only con I found about the RAM was the misaligned heatspreader,
which is probably not a common occurrence. I did not want to remove it and reattach
it properly as OCZ uses thermal tape with the heatspreader.
The price is competitive against other high-performance RAM brands, such as
Corsair and Kingsmax. If you're looking for RAM that scales well with increases
in FSB speeds, than check out OCZ’s PC-2700 Rev 3.2 memory.
