OCZ DDR2 PC2-6400 Platinum Revision 2 Dual Channel RAM
Home : Hardware : Reviews : OCZ DDR2 PC2-6400 Platinum Revision 2 Dual Channel RAM




As you can see, pushing the RAM a bit gets a nice boost in results; up 6.74% for the integer test and 7.57% for the float test. Those timing changes were the limit, by the way; going any further locked up the BIOS completely and required a reset.

Then I went back to the BIOS and adjusted the clock multiplier to 8x and frequency to 275 MHz, giving me the same processor speed (2200 MHz) but boosting the clock frequency between the memory and the processor. Doing so should test the overclocking abilities of the RAM without requiring any additional performance from the processor. Here are the benchmark results:

RAM Bandwidth Integer Buffered iSSE2: 8,605 MB/s
RAM Bandwidth Float Buffered iSSE2: 8,578 MB/s

Again, even better results with a larger percentage change in the two categories: 8.05% in the integer test and 7.79% in the float test. I then pushed the frequency even further; although doing so actually led to decreased results in benchmark tests, it’s clear the RAM can go far beyond the stock settings for additional performance.

Conclusions

Overall, there’s plenty to like about the PC2-6400 Platinum Revision 2 DDR2 RAM from OCZ; it runs without problems, responds well to overclocking and looks pretty good, too. Although there are now faster DDR2 versions out there on the market, the PC2-6400 Platinum Revision 2 is a good solid choice if you’re looking for a high-end RAM solution.

Highs
Plenty of performance available; responds well to overclocking.

Lows
There are faster types of DDR2 out there, so if you’re looking for even more performance, you’ll want to look at a PC2-8000 solution.

Final verdict
If you’re looking for a well-designed piece of DDR2 RAM, definitely give the PC2-6400 Platinum Revision 2 a look.
