i have 8GB ddr2 800MHz Kingston RAM CAS6. i built my PC 3 years ago. I would like to know: is there any 'massive' bottleneck compared to 1600MHz for example?
i recently bought HD7950 boost. my CPU is Phenom II x4 940 @ 3GHz
nice article btw

Why are core 2 Quad's and Duo's never included in benchmarks anymore?
My C2Q 9550 is at 1600 FSB and has 1600 DDR3, so I'm very, very, curious to see the performance differences.

[citation][nom]Crashman[/nom]That comment shows how much you know, I own my basement. Well, technically the bank owns it until I'm 70, but after that I'm home free![/citation]
Ya, somehow people on this site assume that when you are penny pinching it is because you don't have a job... The fact of the matter is that there is only a brief window of time when you have money to spend between that first job after graduation, and when life starts to happen.
When you have a few kids, a house that needs constant maintenance/repair/updating, multiple cars, a wife, and whatever other money sinkholes of debt that you end up in either through accidents or stupidity, $20 becomes a real value of currency, and every $20 you can save on something is good. Or rather put, any $20 you spend on something becomes $20 that does not go to something else (which you will probably suffer for at some point down the road).
But for some of us old time nerds, we need that 'one thing' in our life that is nice, and which we can have some pride in. So our 'spare' cash goes into our computers... but we still pinch pennies because we want to keep our basements!
Personally I am hoping to get my basement paid off by the time I am 50, assuming I don't need to take out a 2nd mortgage for something between now and then (like a new roof or something), then it should all work out well!

BTW, @Thomas
Good article, it really shows what I have suspected for a while now. My system with 1333 runs circles around many of my friends machines which have much faster ram, and it is simply because they allotted a lot more money towards their ram which they stole from their GPU budgets.
Another thing I have been curious about is GPU memory, and how much is needed to play modern games at different resolutions. On my rig it seems that most games play fine, especially with stock settings, but then the moment that I add some mods or play a big open world like Skyrim, then I will start to get jitters with some gameplay. When it happens the GPU load is really not that bad (maybe 30-60%), and I think what is happening is that I am simply running out of GDDR5, and so it has hickups when it is trying to purge some resources, while trying to load others.
Anywho, it may make a good article at some point.

[citation][nom]Proximon[/nom]It needs to be noted that this processor is only rated for DDR3-1600 1.5V. Anything further is an overclock of the processor and voids the warranty. This is also true for any Ivy Bridge CPU.Data sheet is here (page 11)http://www.intel.com/content/www/u [...] vol-1.html[/citation]
True, but at the same time we are only talking about 1866, and while it will void the warranty, the idea of such a small OC doing any damage to your CPU is a little weird. The only times I have ever heard of someone damaging a processor from the Pentium3 era to now has only been when doing much more extreme OCs where you are pushing the system some 50%+ outside of spec. And even then most of the time the system merely becomes unstable, and you reset your settings, and most of the time you are just fine.
That being said, I cannot wait for DDR4 to come out. It will bring much faster stock memory speeds, much higher densities (minimum DDR4 size I am hearing is 4GB), and lower voltages which will keep those higher densities cooler. Hopefully Intel will change their memory controller a bit to take better advantage of the frequency difference, that is something that AMD has always been a little better at.

[citation][nom]TheEvolution[/nom]So,its about memory clock speed ?What about total amount of RAM ?4GB or 16GB or 64GB ?[/citation]
Toms has proved through previous testing that > 6GB is Redundant for gaming & normal system load. Most games right now still do not access more than 3GB. This is why Tom's generally uses 8GB as the benchmark specification. There is no noticeable performance boost by having 16GB or 64GB, as seen in this benchmark : http://www.tomshardware.com/reviews/ram-memory-upgrade,2778-8.html
Given, that was from 2010, it would be interesting if Tom's revisited it to see if programming has changed to reflect higher system RAM, but I highly doubt it has, yet.

I agree with De5_Roy
Since the AMD CPUs seem to behave with more susceptibility to RAM BW and latency differences, it would be great to see a complementary article showing gaming performance differences with different RAM settings on one or two of the currently-recommended AMD CPU platforms.

IIRC, Toms have already done an aticle for APU's.

I was just think about this the other day! Thank you so much for doing this article. This really helps me rethink my next memory purchase.
One thing I would like to suggest: Can you do an article that shows the performance impact RAM has with an APU with no dedicated GPU? I've heard that having faster RAM with an APU can boost gaming performance quite a bit. Some say that an A10 can reach HD 6670 levels if you have fast enough RAM to go with it. I'd like to see the numbers to prove it. Also, does it make sense in a value perspective? If so, where does the value of such a decision drop off in favor of just buying a dedicated GPU?

glad i didn't pay extra for the faster ram, not to mention what a pain it is to find high speed ram for a capacity upgrade a few years down the road like i had to do with my old pc9600 (ddr2 1200)...

I agree they should be fired for making a game so optimized that it runs 100+ FPS and bottlenecks the CPU and memory, take um out back now.

Well that testing was a waste of an afternoon.
Haven't seen a RAM article in a few years that shows any real world benefit of buying fancy ram over stock decent brand ram.
As I say to folks "just buy what colour ram heatsinks suits your motherboard best!"

Honestly, I am still using a system with DDR memory 8Gb and I am able game just fine on it. I am playing bf3 nearing 60fps on ultra. Don't know how either of the memory bound games would fare on it, as I don't play nor am I interested in either of them. But as latency has increased greatly going from ddr to ddr3, my ddr with relative low latency works just fine. It would be really interesting to compare ddr vs. ddr2 vs. ddr3 to see how much the new memory formats really effect gaming. I think that ddr3 has just become predominant in the market due to its low manufacturing cost.
You are not using DDR in any system capable of playing BF3 on Ultra at 60 FPS. In fact if you are talking about the system in your sig you are using DDR3. DDR was made obsolete with Core2. DDR2 was made obsolete with Core i5/i7. At least in Intel builds. If you have an i7 970 you have DDR3 even if you don't know it.
Great article Crashman. I wish you had included single channel performance though.
