DDR3 4GB (2x2GB) kit Ripjaws series-X

Intel P55 as an idol for setting CrossFire on Intel platforms that fit with the price and performance has gone, because now continued a new chipset, P67. Because

the segmentation is not enthusiast, we must abide by the rules of 8x + 8x PCI-E for Crossfire / Multi GPU, not 16x + 16x as what can be done X58. Intel seems to continue the rule that at P67 by offering bandwidth PCI-E 8x + 8x. However, ane feel confident to test with 8x + 8x dual Just remember the difference between 8x vs 16x dual-GPU mode is not less than 5% of the course may please Google. In this brief review, we did with the two test sessions
