The three(triple)-channel DDR3 memory complete set , which are proposed by all memory producers for core i7 system, have the volume 3 X 1 GB or 3 X 2 GB. In the latter case in order to use the whole memory volume it is necessary to use 64-bit software.
Corsair company , published an interesting document (1.05 MB., PDF), which examined the impact of 6Gb memory is games. In this case corsair used the memory dominator DDR 3-1600 (8-8-8-24), which work in the motherboard Asus P6T deluxe (Intel x58) with 1.65 v. The processor core i 7-965 Extreme edition worked at its default frequency 3.2 GHz, with two video cards GeForce GTX 280 ( SLI ) using the resolution 1680 X 1050 and the maximum quality settings. As operating system served the 64-bit version Windows vista SP1.
In Crysis warhead game the minimum frame rate grow twice after the transfer from three to six GB memory. In other games this value is much lower. We note that the average FPS did not grows strongly - by (up to) 10% in Warhammer online, and (up to) 19% in World In conflict. Also Corsair notes a increase in the load speed by 12-23%.
Associates made a analogous test using the processor core i 7-920 overclocked to 4.0 GHz and DDR 3-1800 from Kingston productions ( 3 X 1 GB and 3 X 2 GB ). The video card radeon HD 4870 X2 and Radeon HD 4650 were tested in higher resolutions like 1920 X 1200 or 2560 X 1600. Results came even lower , the game speed was improved by less than 10% in most case . Related Products :
