Neoseeker published a review of Crucial's 2GB (2 x 1GB) PC2-6400 low latency memory
We asked the question "Can we exceed the manufacturer's specifications?"Crucial PC2-6400 2GB Kit Review
The answer is a resounding YES!
I was VERY happy to see how far I could exceed the specifications - running at 1000MHz (PC8000) at 4-4-4-12 timing with 1GB sticks rated at only PC6400 is no mean feat; and provided us with some great benchmark scores.
By 1020MHz we can no longer maintain the 4-4-4-12 timing, and had to slow down to 5-5-5-15 timing to get the system stable; however at the slower latency settings, we were able to get to 1071MHz, so we were able to run these modules slightly in excess of the PC8500 specification; at PC8568 to be precise
