[citation][nom]americanbrian[/nom]I was maybe a little harsh, in that they do not entirely ignore the fact that there is more performance available. However, if you bother to read the link posted in the review (which most people WON'T, which is what makes me call them out) you see that they have RAM available in there lab which they clock to 1866. It is there, sitting right in the lab. And I don't know about where you are but the cost for 8GB of 1866 vs 1600 ddr3 is about $5 US or £3 GBP. Nothing really. From the linked to benchmarks we see scaling in performance only in one game (WoW). I take issue with them choosing the 1600 for the rest of that review too. It is disingenuous in that an inexperienced person looking here for guidance may choose to duplicate that choice when for 1% of the total cost of the system ($5 of $500) they can realise an 8% total gain in gaming performance. This is not really made clear and it is not fair to the average reader...[/citation]
Hmm... Perhaps you were a little harsh, but I might have not been harsh enough too, now that I've read and thought about this post.
Also, about pricing on 1866 memory,
http://pcpartpicker.com/parts/memory/#v=1500&z=8192&t=11&s=301600,301866&sort=a8
The cheapest, quality 8GB DDR3-1600 9-9-9-24 kit is $31 (after MIR, but still).
The cheapest, quality 8GB DDR3-1866 kit has 9-10-9-27 timings and is $42 (also after MIR).
Also, I only counted 1.5V kits and didn't care to see if there are better prices on higher voltage kits. I wouldn't want a higher than 1.5V voltage kit. IDK if you don't mind going to a higher voltage or not, but I wouldn't, at least not with these APUs. One thing going for the 1866 kits is that they have a good chance of being able to be overclocked to DDR3-2133 without unreasonable timings, maybe even at stock voltage of 1.5V or at least below 1.6V. The difference in performance between 1600 and 1866 isn't huge, but 1600 to 2133 is probably a greater boost. I've had better luck overclocking most 1866 kits to 2133 than I've had getting 1600 to 1866 without voltage hikes or crap timings and this could be more incentive.
Still, that price difference is well under (by percentage) the performance difference, so despite my semantic ramblings, you do seem to be correct.
