Corsair and OCZ: New Standards in Fast DDR2

Overclocking (Highest Ratio at Highest Speed) Performance
The Corsair CM2X1024 6400C3 and OCZ TI Alpha PC-8000 VX2 tied for the second highest stable overclock achieved by our DDR2 memory samples. Both reached a stable DDR2-1112, and both were able to run our complete benchmark suite at those speeds. The Corsair booted as high as 1140 and OCZ reached a boot of more than 1130, but neither memory was stable in 3D benchmarks at these speeds.
What this overclocking chart cannot show is the timing advantages both Corsair and OCZ enjoyed at almost every memory speed. Both these specially binned memories exhibited the fastest timings seen with any DDR2 at almost every speed we tested. The advantage over other high-performance DDR2 was not huge, but these two were slightly faster at any speed you might choose. That is then reflected in the performance that can be achieved with either the Corsair 6400C3 or the OCZ PC2-8000 Ti Alpha.

That also is your opinion. To me an elitist is someone who demands a higher standard that the common folk. An elitist to me in the computer industry is someone who buys items that he/she knows will raise the level of standards among his peers. The items this person purchases doesn't necessarily have to be the most expensive but usually demands a higher premium because of the proven value.yacoub - Friday, August 4, 2006 - link
Alas, labeling one an "elitist" has a distinctly negative connotation to it, and that is not an opinion, that is simply how it is (fact, if you will).So by discussing the term elitist, you further the point that those who seek the best bang for the buck are certainly not elitists in the commonly accepted sense. Not to mention your comment regarding a price premium also goes against the core ideology of the overclocker - ie, those who look for what is most cost-effective and NOT premiumly priced. Generally speaking they are items that (at least initially) are lesser-known and often rather cheap because their real potential is commonly unknown. If anything the nature of the overclocker is the opposite of your elitist, in that they are interested in taking common things and making them into superstars, instead of just buying premium-priced items that supposedly have better performance according to the manufacturer's marketing department.

I want, therefore I have.araczynski - Friday, August 4, 2006 - link
thanks for a good read, i agree that the overclocking scale is looks like its designed by some marketing group, stop using that kind of junk.when shown in real scale those small differences are nothing.

Would be cool to see the charts start at scale 0, which would show the rather small impact of overclocking/getting higher rated memory modules. With a scale starting close to the min. score, the increase shown in the chart is not quite realistically represented ;)Did you run into weird results with: DDR2 PC4200 low timings vs DDR2 PC5300 medium/high timings ?

Your comment beat me too it. I also was going to chide Anandtech for producing charts that dont have a scale starting from 0. You should stick to tables, if all you are trying to do is show the number of points difference between one speed to the next.Wesley Fink - Friday, August 4, 2006 - link
Tables are already included as a summary of results for each tested memory. The Corsir table is on page 4 and the OCZ on page 5. The charts are there to show the impact of memory speed scaling on performance, which is not well-illustrated in the table or in our common bar charts. We added a paragraph explaining that scales are reduced to better show the small differences in performance between these two memories.You are both right that charts using zero-based scales will make the differences appear smaller than the reduced scale charts, but we were trying to compare the small differences in the Corsair and OCZ. We do prefer zero-based charts and an explanation was definitely needed.

With the performance of these DIMMs being about the same it really comes down to price, warranty, and reliablity as the deciding factors when you are shopping for RAM.
