So yeah, I ran into Linus' video today about an 8GB kit of RAM from Patriot... Video Yes you heard right, 2.4Ghz RAM. Wow. Available at Overclockers for just under £100
Bought some boggo Corsair stuff that overclocks to 2.4Ghz no bother at cas10, doesn't seem a great benefit to most things, probably quite handy if you use integrated GPU
If it's 1T, it's still not half bad. Some apps are still more about fast memory speeds than about timings, but I agree those timings aren't the best. If you're running something like a Llano, the speed is a lot more important than the timings (though if you've got the speed and the timings, it's even better.)
If there were any veritable benefits, then this would be a lot more interesting. But most of the advantage of higher speed memory is offset by higher latencies and higher voltages, so it's not super exciting. I have tested my system at both 1600 MHz (8-8-8-24-1T) and 2133 MHz (9-11-10-27-1T) and the differences, synthetic or real life, are negligible. I suppose these would make more of a difference in an AMD system, assuming they would work at full speed.
I'd sooner get the same knowing it can hit those kinds of crazy speeds without caring. Aka; Samsung 30nm stuff. 1600 at 1.35, or 2133 at 1.5. Not a bad trade in my mind. AMD systems wouldn't see any benefit from this, save Llano, and that's only because the faster memory actually improves GPU performance (Oh the Irony! llano has a better memory controller than Bulldozer!)
