[citation][nom]A Bad Day[/nom]I was so excited, until I noticed this:I am sad.[/citation]

Timings are measured in clock cycles, so with higher clock frequencies, the same timings number is a lower real-time latency as measured in nanoseconds (or any other unit of time measurement). 13-13-35 at 3GHz is like 6-6-18 on a 1600MHz memory kit. They are very low latency. Complaining about timings like these at 3GHz is like complaining about 5-5-18 timings at 1600MHz, except with nearly the same latency, you have nearly double the bandwidth. It's a win-win for latency and bandwidth.
 
[citation][nom]eddieroolz[/nom]Until just 4-5 years ago we were amazed at RAM that ran at 533, 677 and 800MHz. But 3000MHz? Wow![/citation]

The actual DRAM module speeds haven't improved all that much. The actual chip frequency for DDR3-3000 is around 375 Megaherz. DDR3 chip frequencies are one quarter that of the IO bus frequency and there are two data transfers per IO bus clock. This corresponds to the prefetch buffer size of 8 words per access. By comparison, DDR2 had 4 words per access and DDR had 2.

Thus, the actual memory chips haven't gotten that much faster, the IO bus has.

It depends greatly on the workload. In gaming, higher RAM frequency tends to not help much in the maximum FPS, but it can help in the minimums and in CPU limited games if the CPU is memory bandwidth limited (such as AMD's CPUs and Intel's older CPUs). When it comes to other workloads, such as folding, archiving, rendering, AES encryption on AVX supporting CPUs, and the like, faster RAM quickly becomes important.

Also, APUs (such as Llano and Trinity) benefit greatly from faster RAM.
 
While I don't disagree, you guys seem to be mentioning the exceptions here. Specialized software and the like is not what most people are going to be running.

I would bet money that even though this RAM is technically 100% faster than what I am currently running, I would be hard pressed to even notice much of a speed increase. Specs are cool and all, but I know from experience that they can be deceiving. Don't fall for the numbers game.

Someone who buys 3GHz memory is either someone with a lot of money to throw around for no good reason or is someone who can use the huge performance very well. Your complaint is like complaining about a $2K 3.xGHz eight core Xeon not improving your gaming performance over a $220 i5-2500K. That isn't what it should be used for, so it's not a very valid complaint. It is helpful of you to mention that this memory won't help a lot of consumer/gaming software for most consumers who aren't using APUs, but you're then talking about using it in areas where it should not be used in.

My point is there is no "huge performance" gain here, but obviously you think that there is. Also you are making assumptions based on your opinion who will buy this RAM. I guarantee there will be some power users who think they need this RAM and will buy it. And that's who they will probably market it to, I mean even the name "Xtreem" is targeting this audience. I'm pretty sure Pixar isn't going to be the one buying this stuff.
 


Your point is wrong. For many applications, RAM performance is a bottle-neck and 3GHz memory would help greatly. I'm not making assumptions based on anything beyond what I know to be factual. Just because some people might buy this RAM for workloads where it won't help enough for the cost to be worth it doesn't mean that we should judge it based on the mistakes of misguided customers. This RAM would help RAM limited applications very much and your last post is completely denying that. For those applications, it is worth the money and people using them would be justified in buying it. Rendering, decompressing/compressing archives, some folding applications, AES encryption/decryption done on CPUs with AVX, and more would all benefit from this memory very much and to a lesser extent, APUs (although probably not enough to justify the costs).

Well we agree on one thing, this RAM is a waste of money except for maybe in some extremely rare setups. Soon 3GHz RAM will be mainstream and dirt cheap anyway :)

Extremely rare is an extreme exaggeration. Folding is a very commonly used type of application and so is encryption. Decompressing/compressing archives is also common.

compression and encryption may be common, but needing it to be at 'performance' speeds is NOT common at all. Not saying there are not people who want/need this type of memory... but it is an extremely small part of the population that NEEDs this type of ram in order to work faster.


That said... man it is cool :) Can't wait for DDR4 though.

Click to expand...
This will not happen. Before 3.000MT/s can be made in large enough numbers... and even to think it will ever work with 1,5Volts... mission impossible (both being mainstream and dirt cheap). DDR4 will be faster with a lot less heat and point to point topology. It was the same with DDR2. 1066mt/s was quite a jump in price, 1200 and beyond was also hard to get.

Exactly what I was trying to point out ... Blazorthon go drink a beer or something, and try and relax a bit.
