I'm looking for some DDR3 memory for my rig and came across this:http://www.nextag.com/ocz-ocz3rpx1333eb4gk/search-htmlOCZ DDR3 PC3-10666 / 1333 MHz / ReaperX HPC / Enhanced Bandwidth / 4GB Dual Channel/6-5-5-20I have a Q6600 CPU which I am about to OC to 3GHz (my first OC experience :) ). My current memory is Crucial DDR3-1600 cl 7.Any advice as to whether I am going in the right direction with this memory would be greatly appreciated.Thanks, Bruce.

Unless it's just for the hobbie-fun factor, there's really no FS help to be had by this. O/Cin' your Q6600 to 3.6 will get you a Real 20% increase over a 3.0 clock. We saw the difference between 45ns and 70ns in memory latency to be only (and even explosively) arguable. Each 100Mhz in increased Ram speed will net ~ 1ns in latency decrease. If 70 > 45 could only cause an argument, 55 > 53 would . . .. well, you get the picture. Get your quad up to 3.6, then tweak memory.

I can see what you're thinking with the DDR3-1333. However, personally, I'd stick with your DDR3-1600. This is because the higher rating will give you more flexibility in your choice of FSB straps and dividers. For example, you may find that once you've set your FSB speed to whatever you need to get your Q6600 to 3GHz, your motherboard gives you a choice of (eg) 1100, 1400, 1600 and 1800 MHz for the RAM. With your existing RAM, you could go for the 1400 or 1600 MHz options and be pretty sure you'd get a good result. With the DDR3-1333, you'd probably be stuck at 1100. That answer assumes that you don't already know what FSB speed and strap settings/RAM dividers you'll be getting with your Q6600 at 3GHz. But perhaps you've already done the arithmetic and confirmed that you won't fall into that situation. That is to say, perhaps you've found that given your combination of components, DDR3-1333 hits a sweet-spot in terms of FSB speed, FSB strap and the available RAM dividers on your motherboard. But even then: what will happen if, having got your Q6600 to 3GHz, you find you can easily push it to 3.6GHz? At your new FSB speeds, you may find yourself with a different strap/divider relationship, calling for the extra flexibility of that higher-rated RAM. That is why, buying now, I would always go for the very fastest-rated RAM I could find: it is not just about raw performance: it opens up more options or, more accurately, it prevents options from being excluded.More generally, it is notorious that people have different opinions about the contribution RAM makes to FSX. Personally I have found high-speed RAM to be helpful - not earth-shatteringly so, by any means - but a nice little boost in smoothness. However, it is very difficult to measure such improvements in FSX and of course this means it may all just be placebo - although I honestly don't think so. There are (to my eyes) visible improvements in the "snappiness" of texture loading and even a slightly higher AVERAGE (not peak) framerate. But it can be time-consuming to get all the components singing along nicely together. And whether it's value for money is of course a highly moot point.Tim
