Yea, I thought auto should work, but it didn't. I had to manually lower the RAM clock speed to get all four to work at the same time. The BIOS screens were a bit mind-boggling (very high on graphics, dazzle, and flash -- very low on usability). So it's possible I didn't really have auto mode correctly enabled. > OTOH, since you don’t do hard-core gaming or scientific > number-crunching, it is unlikely you will notice a difference in > your every-day computing. In my case I compared an "emerge" that took several minutes, and it took significantly longer with the lower RAM clock speed. I decided I was better off with fewer GB of faster RAM.
