Neoseeker has published a review of Patriot's high performance PC2-8500 2GB Memory Kit
In short, the Patriot PC2-8500 2 x1GB modules do not overclock that well as far as MHz go - but I was able to get them to run significantly faster then stock.Patrio PC2-8500 Review
As you saw from the charts, I managed to run them at 1044-4-4-4-12 timings - which is 23 MHz lower than the 1067-5-5-5-9 figures, but they nevertheless turned out better performance. Granted, much of the increased performance was due to higher CPU performance, but 1044-4-4-4-12 WAS a part of it.
