The frequency of the RAM is set in the BIOS. I don't think Linux is going "Right boys, I've used 1,333,000,000 cycles of the RAM this second - I'm gonna take everything out of the RAM for the rest of the second and then put it back in when the next second starts." or something like that.on my desktop AMD A10 and have had all sorts of issues getting it to use the full potential of the kit I have in the box. For example, the Corsair vengeance RAM is 2133mhz but ubuntu will only use 1333, and can only see 6.7GB out of 8GB.
So timing of purchase is everything it would seem.
I had looked into the i5 U series, but from the bench tests I saw, the i3H outperformed the i5U on all areas except power usage.
The i3 has multi threading but the i5 doesn't, so the i3H seems more appropriate for my usage?
That's not quite right.
It's best to entirely ignore that kind of trash as it makes bogus comparisons based on junk numbers.
