Legit Reviews posted a review on the OCZ PC2-8800 (1100MHz) Gold Edition Memory

The OCZ DDR2 PC2-8800 Gold Edition memory kit does exactly what it's rated to do and performs very well in all the benchmarks that we threw at it. We were able to reach 1111MHz with aggressive 4-4-4-12 2T timings, but needed to increase the voltage so high that it voided the lifetime warranty to hit stability. At these speeds we were able to get the modules to perform the same as the Corsair XMS2 DOMINATOR PC2-8888 kit, but at the cost of our warranty. When we kept the timings loose and ran the modules at 2.42V (our motherboard didn't have 2.40V) we were able to get the 1100MHz modules up to 1140MHz with 100% stability at 5-6-6-15 timings.
