2x256MB gets better performance than 2x512MB?


Recommended Posts

Both AnandTech and Xbitlabs conclude that 1GB RAM does not improve gaming performance in Doom3 which is the most intense game to date.

According to Crucial (parent Micron is top 3 biggest memory manufacturer), it's not about how much RAM your system has, RAM speed is much more important when gaming: http://www.crucial.com/pdf/CrucialDoom3.pdf


I also noticed that users on 3DMark03 Hall of Fame list are mostly using 512MB RAM. Hence my question: when overclocking, will I get better performance with 2x256MB 3200XL (2-2-2-5) instead of 2x512MB 3200 (3-3-3-8)?


Thank you.

I agree with CMC Savage. 2 x 512mb of the PC3200XL is the way to go. You can have the low latency and a gig of RAM. Also, and especially in P4 rigs, the double sided DIMMs (the 512s are DS) outperform single sided DIMMs (256mb = SS). The memory controller is able to more efficiently access DS DIMMs due to the bank interleave.


For gaming a FAST LOW LATENCY gig of RAM is the :bomb:
