    I have a Asus f6v-v1 it has PM45 chipset, and ICH9-M southbridge. It came with 4gb ddr2. I was thinking about upgrading to ddr3, will my mobo support this?

    Thanks,
    Brian

    no laptop comes with ddr2 and ddr3 slots, so you cannot upgrade.
    The fastest memory you can put in your system is Pc6400 anyways, since that is the fastest supported memory by the chipset.

    You pretty much can't upgrade any more for DDR2, except for the still fairly expensive 2x4GB kits - which is pretty unnecessary for you, considering the laptop you use. As said before, DDR3 and DDR2 are NOT interchangeable, hence you cannot upgrade memory in that respect.

    Not like you will notice any difference. DDR2 is actually a plus as it is cheaper.

    Even if you could, that would be the most useless upgrade you could do, as core2duo systems has the memory interface via the northbridge, so you would be looking at a very very tiny increase to nothing at all in performance. It would be a difference if the memory would be through the CPU directly (like in AMD-systems and the new intel Core i7).

    It depends upon the manufacturer which memory connectors are soldered to the motherboard during the design and manufacturing stage.

    The PM45 chipset supports both DDR2 and DDR3, but since the ASUS came with DDR2 connectors, only DDR2 modules can be installed in it.

    DDR3 modules will not fit in a DDR2 connector.

    He means you are wrong. PM45 supports DDR2 and DDR3, but it depends on whoever makes the motherboard to determine which slots to install (either or, not both).

    A very quick look and hey presto, a laptop that sports DDR3 RAM:

    http://www.rockdirect.com/viewNotebook.php?pName=XTREME%20780

    The reason most hadn't switched to it yet is that it was more expensive. But it's dropping slowly in price.

    Take a very simple example:

    DDR3 1066MHz 1Gb = £16.09
    DDR2 800MHz 1Gb = £11.49

    Not much price difference, but these aint the highest quality, and they are also fairly small. The price increase of RAM is not directly proportional to the increase of capacity.

    Among several others including the OCZ Whitebook and Gateway P-780x series.

    8GB DDR3 >$600 vs 8GB DDR2 <$400. Unless you do work that needs that much memory, it's a waste of money.

    Much better example. I just picked the first one I found. And I totally agree; unless you're processing lots of data (by which I mean lots of graphics, heavy duty maths calcs) then you really are not going to notice the difference.

    170 pounds one modul
    i wanted these :

    I want more ram b'cos I want to ensure my nobo will last for more years (not for games but applc.)
    I replaced cpu P8400 with T9800 replaced 4200 rpm hdd with scorpio 5400 rpm
    now waiting for that memory doh ..
    i still dont understand why that iTunes is quite slow when is opened and crashing when quickly changing tracks ...
    think memory is most important thing to run nobo fluently ...

    OK, we're not trying to convince you to buy DDR3 RAM. Not at all in fact. If your laptop is not offered with DDR3 RAM, then you can never ever use it in your machine without swapping out the motherboard.

    You see the individual RAM modules have a notch in the physical card. The notch aligns with the associated memory bank on your motherboard. This notch is in different places for DDR2 & DDR3, so it will not physically fit.

    We were simply trying to demonstrate why DDR3 is not mainstream in notebooks yet.

    And I guarantee you that you will notice next to no increase in load times for iTunes if you could use different RAM. Stick with the DDR2 rather than the expense of a new motherboard and RAM, and the pain of trying to re-build.

    The chipset PM45 does support DDR2 & DDR3; but the motherboard will only support one or the other. The fact that they offer the product with DDR2 RAM says that the motherboard only accepts that.

    You see, the PM45 chipset will be used on a large number of different motherboards; some which will accept DDR3, some which will accept DDR2. There may even be some that accept both (i.e. having different memory banks available); but I guarantee these are not going to be laptops. Space inside a laptop is limited, so having that level of redundancy is going to be practically non existent.

    Let me re-iterate in one sentence:

    The chipset might accept DDR3, but the motherboard will not.

    motherboard , hmm ... dont understand how motherboard.. Chipset is center to gather all data (we talking about north bridge now) from CPU,RAM,GPU,HDD , that is motherboard so u probably mean BIOS ...

    No, he means that the physical motherboard only has one type of slot built into it: DDR2 OR DDR3. The chipset in this case refers to the Northbridge and Southbridge. They are designed to support both, but the motherboard only has physical slots for one. Therefore you are limited by the physical connections. If your motherboard has DDR2, then you can only use DDR2. You can never upgrade to DDR3 because you have no connector.

    Btw upgrading your memory and CPU do very little to boost your system up (unless your CPU is at 100% often then it would make a difference). The major limiting factor is the slow hard drive. Going to 7200 RPM or even a SSD would be a much more worthwhile and cost efficient upgrade. Memory prices will always drop, for both DDR2 and DDR3 but even at $100, it's much better to spend that $100 on a new SSD.

    What? all these component are most important cpu ram hdd
    of course hdd too all these things have influence on each other but yes hdd is the slowest component on personal computer (ssd not included)

    but now u saying that i will never run ddr3 and guys above saying that i will so who is the right?

    What he means by this is let's say you have a choice between a P8600 running at 2.4GHz and a p8700 running at 2.53GHz. You really are not going to notice a massive jump in performance for the extra money, unless you are doing work which is really processor intensive.

    Likewise the same can be said about RAM speeds, amount of RAM etc.

    Unless it is a big jump between the two - i.e. jumping from a T2330 1.6GHz to a p8600 2.4GHz, you wont see a massive improvement in performance.

    The main thing to see an improvement, is to ensure that each upgrade works with the other upgrades you've got. It's not good having a processor which has a FSB of 1066MHz if your chipset only supports 533MHz for example, it would be better to spend the same amount of money but spread it on a better chipset and a lesser processor.

    my laptop is aw11sb
    and i upgraded cpu removed P8400 with T9800(ES) 1066Mhz bus (2x533)
    now if the processor running on 1066Mhz the ram ddr2 must run the same speed or not
    bcos IF am running 1066mhz CPU and rams runnin on 800Mhz (2x400)
    the cpu MUST fall into line with ram speed
    SO ram and cpu MUST be equal 1066 and 1066

    I think the easiest willb be I'll go to some IT industry and i test and try put some ddr3 rams in laptop and I will see
    All right thank you very much for information

    I work in IT, have done for the past 10 years and I 100% guarantee you that no IT specialist will be able to put DDR3 RAM in a motherboard that caters solely for DDR2 RAM as your machine will. But go speak with someone if you must. Good luck with that

    This is not correct. RAM and CPU rarely equal. There are ratio dividers to make them equal. You are running DDR2-800, check GPU-Z. If you look at the memory tab, you will see that you are running a 4:3 divider to get the 800MHz of the memory run at the 1066MHz of the FSB. Let me state this again, you have DDR2 memory. Without modifying your notebook, it will never be able to run DDR3 because they are not physically compatible. While you might know about repairing and recovering, that has no correlation with understand how each computer hardware is linked together and how they work.

    CPU and RAM are important parts of the system; however, they are not limiting your system, therefore upgrades rarely are useful. An example would be if your old CPU was a 4 lane highway. If you only have 2 cars then you can never jam up the highway (never stressing the CPU), so upgrading the highway to 8 lanes (new CPU), won't make a difference. If there are 5 cars (stressing the CPU) in a 4 lane highway then (the old CPU) is limiting and upgrading will make a difference.
