Tweakers Asylum has put up a review on the AOpen AX4BS (Intel i845) Motherboard
One of the biggest concerns with using SDRAM, even running at 133 MHz, is can it keep up with the Intel P4? The Intel P4 processor uses a blazing fast 400 MHz FSB which ends up equating to 3200 MBs of throughput. When combining this with PC133 SDRAM, which has a throughput of just 1064 MBs, you can see where the “bottleneck” factor will come into play. In contrast, PC2100 DDR SDRAM would offer up 2100 MBs throughput putting it much closer to the P4’s level.Read more
