This review showed some interesting results when using Fast DDR3 with intel GPU (which the m17xR3 can use and save much more battery over 6970m for portable gaming once in a while)

The performance numbers from upgrading the memory was insane. We saw performance gains from 6% to 86% depending on the benchmarks with the largest performance gains coming from graphics intensive games. Who would have thought that the area that gained the most was the frame rate in games? If you want to get better performance out of the Intel HD Graphics 3000 GPU on your Sandy Bridge laptop this is more than likely the best way to go about it. You can literally feel and see the difference in everything that you do on the system, so this is an ideal upgrade for those that want 8GB of memory and better performance.
When it comes to pricing the Kingston HyperX Plug and Play 8GB 1866MHz kit that we looked at today (part number KGX1866C11S3P1K2/8G) will set you back $163.00, but it's worth every penny of it. Next to a Solid-State Drive (SSD) this is the biggest performance upgrade that you can do to your laptop.
--------------------
I'm not sure how can the laptop benefit from 1866 memory? not sure if it's worth upgrading to 1866 DDR3 with 2720QM? those will be beasts for the m18x though

its because the intel integrated gpu shares system memory.
normally gpu memory is insanely fast vs. desktops (gpus are the most advanced pieces of tech in pcs).
your difference in games with 1866Mhz ram + 6970/gtx 460m with or without crossfire/sli will be like 1 frame.
im not spending $3000 to use an intel integrated gpu to play games @ 800x600 on a 1080p screen. -

Eh The review was skewed. If I'm not mistaken, they compared 6gbs to 8gbs, and the 6gbs were mismatched anyways. Level the playing field... It's like comparing an i7 2920xm oc'ed to a 840qm stock.
Yes, 1866Mhz memory will have gains, but they will be so minimal that it really isn't worth it.
If there was to be a real comparison, say between that 1866Mhz and its 1600Mhz Kingston HyperX counterpart, then I would be interested in those results. -
Let's take a look at even faster memory, desktop memory.
Indeed, DDR3-2000 doesn't provide big performance benefits in real applications. Its average advantage over DDR2-1667 with the same timings is a mere 1-2%.
a whopping 300 points diff in vantage
5 fps in games @ 1680x1050
itll be even less at 1920x1080
here's another test with 1866 vs. 1333 memory

conclusion
However, the primary conclusion that we can draw from the results of our today’s test session is that the performance of dual-core LGA1156 processors doesn’t seriously depend on the memory speed.

We are talking about sandy bridge here not previous intel cpus and AMD, I'm not saying the improvement will be noticeable at sandy bridge mobile but the review i linked claim it does because Sandy bridge can benefit from better ram . -
no offense -
I just wanna know if it's worth paying to be used for my m17x R3
The review says it does but some people here say it doesn't and trying to prove it with none sandy bridge cpu which doesn't make sense, the review claim sandy bridge can make a use of the extra high speed that's all. -
If there must be a comparison, let it be between 1866Mhz and 1600Mhz RAMs of the same size and made by the same manufacturer. A lot of us have upgraded our RAMs to 1600Mhz ones already (most notably to Kingston Hyper X) and that's like 7.8 in WEI, seeing how expensive 1866Mhz rams are they just seem unnecessary.
