In many ways, this memory was very disappointing. Out of the box it ran at completely wrong timings, and had to be changed manually in the BIOS. The choice of using 2x256MB sticks seems wrong too, leaving little room for upgrading as most boards have only 3 DIMM slots and any power user nowadays would want 1GB at least. Although they do 1GB sets, their 512mb set having 1 512MB stick and the 1GB set having two would be preferable. This aside, after setting the speeds correctly, it was only 2% faster than the A-Data memory. This is most likely because of the latencies introduced having it across 2 DIMM sockets. This set is very expensive, but in its defense it is capable of running at up to 533MHz while retaining its low latencies. This is quite a feat. From the limited sample we have seen today, I would suggest this is the memory to go for if you are aiming for a high front side bus overclock.

This RAM is half the price of anything else in this selection and offers excellent value for money. This would be our personal choice, but then we are big on value for money. Don't expect to be achieving high overclocks, but with the money saved you could get that faster CPU you always wanted.


Conclusion

Low Latency memory does not offer good value for money, that we knew, and now have proven so. What it offers you is the best performance you can hope for, and the best potential for overclocking. When you are building a machine designed to be nothing but the best, it is all the little tweaks that add up. 1% here, 3% there and pretty soon you are running a machine 20% faster than others in its league. For those of you who fall under this category, the Corsair XLPRO is the more desirable.

Cheap memory should be avoided at all costs. The best memory to buy is somewhere in the middle, like Crucial, A-Data or even Corsair's new Value RAM.

We haven't tested enough memory here today to suggest through and through what is the best memory to buy. But hopefully the information we have given will help influence your buying decision.
