    I realize that 8gb DDR3 for laptops probably doesn't even exist yet, and I also realize the spec says the laptop only supports up to 8gb of ram, but is it possible that 16gb (2x8gb) will be supported in the future?

    8 GB sticks do exist, but they are mad expensive (700-800 per stick in Alienware, 2000 a pop in M6500/M6600).

    Sandy Bridge technically supports 8 GB per DIMM, but again insanely expensive.

    I have another question about RAM. The l502x supports 1600mhz RAM right?? How many pins. Is it DIMM or SODIMM? I have been jumping back and forth between crucial and tigerdirect looking for RAM and it seems to me that all the stuff on tigerdirect that says "desktop" RAM is the same specs (PIN numbers and what not) as the RAM that is being recommended to me by the system scan thing on crucial. I want 2x4gb sticks of 1600mhz RAM with the lowest latency possible. any help would be appreciated. Links to somewhere comparing a few different brands that you guys think are good would be GREATLY appreciated. Thanks all

    I dont know about the 15 but on the 17 1333mhz is the highest speed regardless of cpu. And its sodimm. Yeah the xps laptops support up to 16gb and 8gb sticks are rare and expensive.

    XPS 15 is kinda weird. Most people's 1600 mhz ram downclocks to 1333, but some users have been able to run at 1600 mhz for some unknown reason. I have no idea whats going on with regards to this issue.

    Some of that may have to do with what cpu is being used, right? i7-2630qm only supports DDR3-1066/1333, but i7-2720qm supports DDR3-1066/1333/1600, for instance.

    Well yea, those with the better CPU are the only ones where it works, but those are also the only ones getting said RAM to try. In nearly every case, the RAM downclocks to 1333MHz due to Dell and their BIOS restrictions.

    RAM speed is almost a non-existent issue. You would be better off with more RAM than faster RAM. Faster RAM yields no performance gain for normal usage. Even in synthetic benchmarks and rendering the performance gain isn't that much.
