Performance in 3ds max 7
The popular professional application for 3D modeling and rendering, 3ds max 7, doesn’t show any significant performance jump when we increase the amount of system memory. However, we do notice some positive effect from the second Gigabyte of RAM we install.
For example, when we run SPECapc test in viewports, the performance improves by 3.2% with four DDR400 SDRAM modules (512MB each) and by 4.3% with two DDR400 SDRAM (1GB) modules. In other words, the positive effect from the larger amount of RAM is even higher than the negative influence of the 2T memory timing when all four memory slots of the mainboard are occupied.
During final rendering in 3ds max 7 the situation looks very similar, but the effect from the additional system memory is somewhat smaller this time. The platform equipped with two 1GB DDR400 SDRAM memory modules is only 1.9% faster than a platforms with two 512MB DDR400 SDRAM DIMMs.
Even though we have finally managed to detect the performance growth from the use of 2GB system memory, we can hardly regard it as a significant improvement. The ordinary user will hardly sense a 2-4% performance growth.
