    Since Dell is charging bunch of money for upgrading my m18x memory, so I decided to stock it (4GB SODIMM 1333 2x2GB), and now open this topic to discuss about RAMs (size, speed, CL etc...) that good for our purposes as well as the availabilities.

    My first priority now are 2 pairs of Kingston hyper x PC 12800 1600MHz (4x4GB). However, they are most likely out of stock right now, and Kingston says that they'll probably be available on may 10th. But on top of that, I have found some complaints about the oversize preinstalled heatsink that interupts the internal air flow causing the laptops overheated (Alienware m15x).

    If there's somebody already experienced this issue, please share out ur opinion. If that was true, I'd switch to another without heatsink.

    Thanks for reading guys ;)

    that might be a problem with the smaller laptops. but i had these in my m17r3 and i never had any problems and the m18x is huge so i doublt there will be any air flow problems with this beast ;) now the real question is 1600MHz or 1866MHz hyper x RAM :D

    I'm thinkin 1600 hyperx. Uses less power (pretty sure), won't get as hot and you won't notice the 5% speed difference, and the price on the 1600 C7 is not horrid.
    $.02

    It seems to be sold out everywhere (in the U.S.). Looks like plenty of others have the same idea.

    According to Kingston, they'll be available on may 10th (u can make an order directly from Kingston, and that'd be more reliable about the availability IMO), plus the first m18x shouldn't be shipped out before May 20th I guess, so we still have plenty of time to look for some back up plans. Anybody having other options?

    I would also try Samsung RAM as another option, but the spec (CL 11 compared to CL 9 from Kingston) and price ($67 for a single module x 4) are not really interesting me.

    wonder if we can convince them to use 1x4gb instead of the 2x2gb for the stock ram.. would be much more convenient

    And the intel product page for SB says the processors only support 1333mhz or1600mhz?
    So how can 1866mhz run??
    Read on this topic... something about JEDEC.. what is that exactly??
    And any 2166 ddr3 ram available for notebooks??

    1866 is the highest and was just released, and yes it work native 1866 with sandy bridge laptops without changing settings or bios, that's why it's called plug and play but it's quite expensive and unproved if it actually help performance, the difference between 1333 and 1600 was not much.

    Sorry, I do have a question. Due to my work, I need 16GB RAM min. I quoted on the new M18x yesterday both 1333 and 1600 16GB+ RAM have quite a bit of price difference....:(

    Is it safe to say that I can go for 1333 first and upgrade to 1600 later when I have more spare money? Or it is not worth to do so at all?

    Thank you in advance!

    That massive price jump is why nobody is buying anything above the stock ram from Alienware and buying it from resellers like newegg. I think it's like $600 for 16gb of 1600 memory, when you can get the same from newegg for $220.

    Here's all the HyperX ram from newegg and you can set the speed you're looking for on the left.

    Value RAMs should be known as the cheap RAMs compared to the high performance RAMs with better spec.

    the RAM u posted up there is PC8500 which is running at 1066MHz. Imagine that, the higher speed gives the better rate of data transfer per second. So I would say that no matter how large (zise) ur RAM is, the lower speed gives u the smaller bottleneck.

    For P67 Intel chipset (that run with Sandy Bridge processors), maximum RAM speed could be up to 2133MHz (but 1866MHz is the top on the market right now).

    I dont think thats smart to replace 16GB 1333MHz by another 16GB at 1600MHz, because you will NOT see much difference compared to the money that cost you. And yet, in DUAL CHANNEL memory, to take advance of the maximum ram speed, you have to use all RAM modules at the same speed, otherwise, your system will run at the speed of the slowest module. For example, when you install 2 x 2 GB 1333MHz and 2 x 2 GB 1600MHz ( since there are 4 RAM slots on both sides of the m18x mainboard), then the machine will recognize your RAM at 8GB 1333MHz.

    Hope this could help you out.

    Guys, sorry, I'm confused.

    What ram is it I need to order? I want to be able to go up to 32 gigs, so I need 8 gig sticks right?

    I bought the base ram and intend to upgrade myself so if anyone can share what the best ram is that I can buy for the M18X with a link it would be much appreciated!

    Like a said above, since the m18x mainboard has 4 RAM slots (2 on bottom & 2 on top, that means you have to open both top and bottom sides of the machine if u intend to upgrade it yourself). You ca refer to the manual document / memory for more detail.

    Back to ur question, yes u definitely need 4x8GB stick to make up 32GB RAM. For RAM size, I would say that 16GB is way enough for a laptop nowadays. About RAM speed, that depends on the purposes of using ur laptop. You shouldbe alright with the 1333MHz for daily tasks such as casual games, Internet, emails, etc.. But you may consider the higher speed (1600MHZ, 1866MHz) for some hardware-killing games (Crisys 2, upcoming Battle field 3 or something like that). Please note that the best 8GB Module is now only available at 1333MHz.

    I have been shopping around for a while. All I would suggest are:

    * Kingston Hyper X 16GB (4x4GB) 1600MHz
    * Kingston Hyper X Plug n Play 16GB (4x4GB) 1600MHz. (this one costs u lil' bit more but keeps u away from headache changing some setting in BIOS).
    * Kingston Hyper X Plug n Play 16GB (4x4GB) 1866MHz. (more expensive for smoking speed ^^)
    * OWC 32GB (4x8GB) 1333MHz (probably costs you $900)

    Please note that none of those except the 32GB 1333MHz are available at this time. (hopefully on May 10th). You should check manufacture website or Newegg for detail.
