Advice: most of the motherboards by default sets the voltage to 1.5V, this memory needs 1.7v. At 1066MHz it worked ok at 1.5V, but then I manually went the FSB of the system so the memory would work at 1333MHz the system did not pass the POST. With changing the voltage it work perfectly at 1333MHz.

Now I am using it at 9-9-9-24 CR1 1333MHz with no problems. The bandwidth is similar to a extremely low latency DDR2 @ 667MHz, standard DDR2 @ 800MHz or a habitual DDR2 @ 1066MHz.

Latency is in this vicinity 69ns and bandwidth of 7100MBs. Numbers from Everest read test. (6800MB @ 1066MHz, 7100 @ 1333MHz CR2, 7300 @ 1333MHz CR1).

So, what is the catch? I went for DDR3 because I was building a system with the intention of would last me for a long time, with the intention of may maybe support the new processors and new memory, so I chose to bought a ASUS P5E3 Deluxe MoBo. This one needs DDR3, but I was not willing to pay $400 for the memory so I found this one at $110. Excellent DDR2 was around $85 at the time, so a $25 diference was not terrible.

It works as confirmed by the manufacturer, a small bit confussing because it seems as a 1066MHz memory with the intention of can be OC to 1333MHz.

With a week of having them established I changed the timing to: 9-7-7-23CR2 @1333MHz, new Everest value is 7596MB/s. For now all is working ok, will try a longer Prime95 stress this weekend.

June 9: system passed the Prime95 stress and went for a more agressive timing. Now it is 9-7-7-20CR1 @ 1333MHz.
