Command rate and CAS Question Tags: Memory Latency Patriot Command Prompt Product Last response: June 2, 2006 2:27 PM in Memory Share kobe08 June 2, 2006 12:40:58 AM I am planning to buy new RAM. Please help me decide which is better between these 2 modules: 1. Patriot: http://www.newegg.com/Product/Product.asp?Item=N82E1682... It has CAS 2 latency 2-3-2-5 timing. It said somewhere in the reviews that it has 2T command rate, not sure if it is true pls help. 2. Corsair: http://www.newegg.com/Product/Product.asp?Item=N82E1682... It has CAS 3 latency 3-3-3-8 timing I've read from the forum that lower numbers mean faster memory if so, the Patriot should be a better buy. Please correct me in this. Thank you.

Thanks for the reply. I thought the stock speed on the Corsair is 3-3-3-8? I don't think I can adjust the timings on my mobo. If so, which of the two is faster at stock speeds?
