SUMMARY: In our latest article we are comparing the performance of some of the top brands in DDR-2 memory modules. We've got modules on the test bench from OCZ (PC-5400 Performance series), Corsair (XMS2 Pro series) and Kingston (HyperX series). After taking a close look at each set of Dual Channel modules, we tested them at their default speeds and as far as we could overclock them.
The first set of Dual Channel modules we are taking a look are from OCZ and are part of their Performance Series which come with a copper heat spreader and tight timings compared to cheaper memory in the same range.
I remember the days when OCZ first started with their plain and not terribly exciting memory modules but those days have long gone and OCZ now produce some of the nicest looking modules on the market, in our opinion. The heat spreader isnt light and feels like it will actually help with heat dissipation compared to some other modules which are much lighter. You feel as if you are actually getting something more for your money.
The memory comes in simple retail packaging as you can see from the photo above - Nothing too exciting but effective none-the-less. You can choose either 1GB (2x 512MB) or 2GB (2x 1GB) Dual Channels kits; in this article we used the 1GB kit. At the time of writing the 1GB kit will set you back about $237 US on Newegg.
Above you can see that the OCZ Performance Series PC-5400 modules are rated with timings of 4-4-4-12 but in fact the sticker is incorrect and the memory SPD is set to run at 4-4-4-8 which tightens things up even more. These timings are a good deal tighter than the standards that JEDEC have set out.
Some performance OCZ RAM comes with a feature they call EVP or Extended Voltage Protection which allows you to increase voltage to reach higher clock speeds without fear of loosing your warranty. The standard voltage of these sticks are 1.8V but OCZ state that they can handle voltages up to 2.2V ±5% and still be covered by their Lifetime Warranty.
We had no issues testing the OCZ DDR-2 at 2.2V throughout our entire testing phase which is a great sign especially when it comes to overclocking because at this voltage level it gives you plenty of room to work with compared to other modules which arent able to run stable with their voltage set this high.
The OCZ memory is looking good so far but lets continue on and see what the other companies have to offer.
As a business owner, or someone responsible for network security within your organization, you need to understand how to prevent attacks and eliminate network weaknesses that leave your business exposed and at risk.
