Tech Review - Corsair PC-4400 Platinum Series Dual Channel Memory
Hello again, my name is Rodney Reynolds and welcome to another video review. Today, I’m looking at the Corsair PC-4400 Platinum Series dual channel memory. The speed on this memory is 550 megahertz DDR or PC 4400 and has a CAS of 2.5. The complete memory timing is 2.5-4-4-8. Now what does DDR and CAS mean?
DDR stands for Double Data Rate and that means it doubles the bandwidth of the memory by transferring data twice as fast on both the rising and the falling of the clock cycle. CAS stands for Column Access Select or Column Access Strobe and that essentially means the number of cycles for the memory to get information and then process that information.
Also keep in mind that a lower CAS is much better than a higher CAS. For example, a CAS of two will result in better memory performance than 2.5 or three, so try and keep CAS as low as possible when overclocking.
This memory is also dual channel which means better overall memory bandwidth resulting in superior performance, but in order to benefit from this technology you will need to have a dual channel motherboard.
Non-dual channel motherboards do not have to fully independent 64-bit memory controllers, but dual channel boards do which means they have it 128-bit memory interface. Now this memory will work in a non-dual channel motherboard but the overall performance will be much less at the same megahertz.
This is a one gigabyte kit. You have to match 512 megabyte. Modules, they are dual channel of course and this memory is rated office for RS 275 megahertz or again, 550 megahertz DDR.
The timing on this memory is 2.5-4-4-8 and the memory has a platinum heat spacer and this will help dissipate the heat because of course at those very high speeds this memory does get a pretty hot. Now let’s have a closer look at the test system and the results.
If you’re in the market for memory but you want to be guaranteed of a high front side bust well, this would certainly be it the default is 275 megahertz or 550 megahertz DDR. I was able to get at even higher off as far as 285 megahertz. Now 285 was the absolute limit for my particular test set up. I suspect that probably even go higher then at 285 megahertz, that’s very high and of course and that high speed the results are fantastic. Overall, this is a kick ass product.
