I thought dual channel required matching pairs? If so then buying two sticks of 1GB ram at different times making them not match defeats the whole purpose of dual channel.

Doesn't this notebook have Dual Channel support? If so, you guys should be getting 2 sticks of memory to maximize performance.

Dual Channel doesn't NEED two matching pairs... it just guarantees that dual channel will indeed work (properly). At least that's my knowledge of it... since I used to run dual channel on my AMD desktop system (Abit NF7-S nForce2 motherboard...)

Match pair would be matching in terms of

* Size
* Speed
* latency

Just in case you dont know what a "print server" is. Basically your router (wireless or wire) will have a printer port where you connect the printer to it instead of the computer. OR if you dont have a print server, you can always "share" your printer then other computer on your network can print from it. The only drawback with that is if you want to print, you have to turn on the computer that is directly connected to the printer. While if you have a "print server", your router will always be on and all you need to do is turn on the printer and it will print from any computer. I think all the information I given is correct.

Ok... now I'm certainly confused...

Does dual channel require 2 memory sticks or not?
please verify as I've already ordered 2 memory sticks for future investment...

If i'm not wrong (i think this was from tomshardware)
the current cpus (dothan) do not help to bring the performance boost dual channel offers, meaning there is a bottleneck somewhere (which might be the cpu)... but the dual channel would definitely help if the cpu was upgraded or the gpu limit is reached i guess... or something needs to be faster (dunno)

thats why tomshardware stated that the dual channel would benefit laptops with integrated graphics rather than dedicated graphics because of the high transfer rate between the main memory to the shared graphics processor, since dedicated gpus already have high transfer rates because of their own memory...

am i right or not? help me out here...

Aside from some synthetic benchmarks, dual channel DDR2 does not help the the PM very much. DDR2 533MHz gives 4.3GB/s of bandwidth to the CPU which saturates the FSB of 533MHz as well. Therefore putting it in dual channel and giving it ~8.5GB/s doesn't do much as the 4.3GB/s FSB is already saturated.

As the previous poster said, dual channle would help with integrated graphics as that uses up the memory bandwidth as video ram bandwidth.

doesn't ddr2 use less power

ddr3 uses even less 1.8v (out in 2006)

DDR2 uses 1.8V. I believe DDR3 uses 1.5V

isn't this a thread for the ASUS Z71V? stop going on about memory! make your own thread or keep it on topic, please.

Hi, all. I just pre-ordered a Z71V from Integrated System Tech. Regarding your dual channel discussion, I asked Rick, and he said that there was an advantage of 2x512 MB over 1x1 GB, but he didn't specify how much. I figure, by the time I need to upgrade the memory, the prices will have gone down a lot, and I'll be getting better performance in the meantime. What do you think?

Yes there is. If you use 2x512, you are able to take advantage of dual channel memory vs using only 1x1GB

Here are a few reading for it:

What is dual-channel DDR memory?
The terminology "dual-channel memory" is being misused by some in the memory industry, which can mislead the consumer. The fact is there's no such thing as dual-channel memory. There are, however, dual-channel platforms.

When properly used, the term "dual channel" refers to the DDR or DDR2 chipset on certain motherboards designed with two memory channels instead of one. The two channels handle memory-processing more efficiently by utilizing the theoretical bandwidth of the two modules, thus reducing system latencies, the timing delays that inherently occur with one memory module. For example, one controller reads and writes data while the second controller prepares for the next access, hence, eliminating the reset and setup delays that occur before one memory module can begin the read/write process all over again. Think of it like two relay runners. The first runner runs one leg while the second runner sets up and prepares to receive the baton smoothly and carry on the task at hand without delay. While performance gains from dual-channel chipsets aren't huge, they can increase bandwidth by as much as 10 percent. To those seeking to push the performance envelope, that 10 percent can be very important.

So the next time you come across a product that's touted and sold as dual-channel memory, know this- It's simply two DDR or DDR2 memory modules, packaged and marketed as a specialty product or a must-have "kit." If indeed you have a dual-channel platform and you want to take advantage of the performance gain it offers, our advice is to opt for high quality and service over expensive packaging, and simply purchase your DDR or DDR2 memory in pairs. However, be very careful to order two modules with the exact same specifications; the modules must be identical to each other to perform correctly.

The 2x512 is only avaliabe with the Infineon RAM appearently. Anyone know anthing about this brand? Is it reliable and high-quality?

Anyways, I'm going to emial IST and see if they Samsung in the 2x512 config. Also I want to find out if they have a 8x/4x DVD-+RW drive avaliable. The current one is just 4x/2x, so I would like the faster one. Off the email goes...

I've used it on my desktop before. No problem with it.

Keep in mind that even though the RAM is specified as Samsung or Infineon, it doesn't mean it is made by them. The chipset is made by them, but not the board and assembly.

For example, if you buy Kingston the chip they use could be Samsung, but the board and assembly is Kingston, etc.

In my experiences and working with RAM in my past life, 75% of all RAM faulty problem is with the board it is on, not the chipset. There are places that will take the ram, remove the chip and put it on the new board and resell it eheheh

Excellent,

these are the things i like to hear.

So getting 2 mem sticks was a good idea for the z71v even thought performance gain isn't too much...

mind u the 2 mem sticks were the same price as getting a 1 gb stick.

i seriously don't think applications would require 2 gb of ram in 2 or 3 years...

gracia tutti

Just a continuation from my last post...

The drive included in the computer from Z71V is actually a 8x/4x DVD+-RW.
As for the RAM, they may receive some 512 meg Samsung sticks before the computer ships, and if they do they are going to replace my current 1x1024 Samsung RAM with 2x512 Samsung RAM.

Yay IST!

Quick Q's:

I have a few questions for you all, if you wouldn’t mind helping me out: What advantages are there to pre-ordering the Z71V? Does anybody here expect the price to be lower on the barebones or components if purchased in June or July instead? Also, besides DDR2, non-integrated video, and better screen resolution, are there any advantages of the “V” over the “A”? Oh, and does anybody have any thoughts on the “A”?

Thanks!

I must say even if the theoretical 8.5 GB/sec dual memory is an overkill in the z71v. It probably won't be too much of an overkill if you're multitasking lots of applications at the same time.... playing a game, writing cds and playing music on the same computer at the same time i guess

V also has SATA instead of just ATA

I'm surprised theres no dual channel on the A version
also according to istnc.com the A version seems to use a S/W codec for audio...

According to Rick the price might go up for the V due to screen shortages of WSXGA...

I reckon prices would probably just be the same maybe
