I know that memory bandwidth and memory latencey are two different things. So would using PC3500 rated for CL 2.5 be able to run at CL 2.0 better than PC3200 rated at the same CL 2.5? This assumes that the PC3500 is undeclocked to 400 MHz.
In other words does memory engineered to work at higher bandwidths also work better for lower latencies?
well basically it all depends on the quality of the ram in the first place. Lets say both pieces of ram were equal in quality and were designed to run at 2.5-3-3-6, and both were clocked at 400Mhz then theoretically the PC3500 would be able to manage slightly better timings because your running the frequency under the modules designed level.
This is intirely theoretical and may not actually happen in real world application. However it has been my experiance that most of the time you can infact manage hotter timings by underclocking ram.
i disagree...its not like pc3500 ram runs more efficiently at 3200 speeds...its not like the either module is gonna have any errors or anything like that...it just doesn't make sense to me. So IMO just buy ram of the frequency you plan to run at/overclock to and don't waste your money.
