No. I know as a fact Crucial only used 6ns memory on their 64MB 8500LE while everyone else was using 3.6ns or faster memory. So the card was extremely underclocked and not overclockable. I suggest you go to Newegg and read the user reviews. You'll find stuff like the Saphire 64MB 8500LE's mostly come with fast memory, while the 128MB version from the same company comes with 5ns memory. You'll be able to pick and choose, and come up with the fastest solution. 128MB won't help your performance, faster memory on the card will.
