    Really need a definitive answer to this.
    Will 8gb (2 x 4gb) of 1866mhz Kingston hyperX Plug n play RAM run in the P150EM / NP9150?

    It should work fine, but whats the point in wasting money on 1866 RAM? I'd stick with 1600 or 1333 as you will barely(never) ever notice a difference.

    @exposed88 I can get it for cheaper than 1600 RAM so why not.

    I appreciate the feedback but I would like a few more users to chime in. Any resellers / builders care to comment?

    It's not the speed that is important, especially since P150EM doesn't have overclocking and the CPU/Chipset supports 1600, that means your 1866 ram will just run at 1600.

    The other part is, latency matters A TON more than the speed. A really low latency 1333 will likely outperform the 1866 ram in actual use.

    Get whichever is cheapest, if that's the 1866 kit then that's fine. It will work just fine, just don't expect it to be any better in real life situations if you have a discrete gpu since it will never be the bottleneck in your system.

    Make sure it's in the JEDEC table and not XMP tho.

    Max RAM speed supported is 1600mhz. You can still put in the 1866mhz since its cheaper but it will downclock to 1600mhz.

    So, if i were on newegg, looking for RAM, what would I be looking for? I read to try to find 1.35V as it saves a bit of battery, and obviously I need DDR3 laptop RAM, but other than that, I'm not sure what I'm looking for. I see on the newegg sidebar a search narrow for "Cas Latency" which is what I'm assuming hulawafu is talking about? I'm not sure what you're talking about though, hackness.


    Also, side note, I see there are 3 types of 1333MHz:

    PC3 (10600)

    PC3 (10660)

    PC3 (10666)

    What's the difference, and what would I use in an NP9150?

    That will run at 1333MHz as it's XMP RAM which the P150EM does not support.

    Hmm thought it'd run at 1600 since Ivy supports 1600

    paging mythlogic. They sell 1866 hyperx ram with the 150em, I'm sure it runs at 1866 and all the previous comments are wrong.
    They posted benches with the previous gen laptops on here before.

    'The Kingston HyperX PnP will NOT clock down to 1600mHZ OP. Other RAM speeds are down clocked such as the Corsair Vengeance but the Kingston PnP's have been actually found to be working, whether its due to the RAM automatically self over clocking or not isn't really confirmed.

    In fact someone over at m17X section was able to successfully use them at the suggested speed but wasn't able to use the corsair Vengeance at 1866 even after manually over clocking them. Thats personally why I returned mine and got the PnP instead, and TBH to the people saying its not a huge increase even at CL11 the difference is anywhere from 2~3FPs under stress and over 5~10+ at higher frames, and in my books thats a lot.

    City where did you get those frame rate differences from? I think 5~10+ is highly unlikely.

    Exposed88 that ADATA RAM has a 1600MHz profile stored as an XMP profile which the P150EM cannot use. You need RAM with a 1600MHz JEDEC profile.

    Have you personally confirmed that to be true?
    That is, the RAM in question running @ 1866 in a NP9150?

    Can you take a screen shot using CPU-Z and post here (Memory tab and SPD tab)? I'd like to know if the KHX1866C11S3P1K2/8G has the 1866 in JEDEC or XMP.

    I don't have them installed Yet, but I don't see how there would be a difference between an I7 in Alienware and sager. Also found these a few minutes back, http://forum.notebookreview.com/ali...nware-m17x-benchmark-thread-part-4-a-235.html

    Again too lazy to find the original m17x but if you google key words im sure you'll find it. The pnp worked without adjustments again most likely due to there pnp technology. The above post wasn't even the first one in fact in terms of modifying to gainhigher MHz

    Also posted this multiple times every single time ram speeds are mentioned: DDR3 SDRAM for Sandy Bridge: Choosing the Best Memory for LGA1155 Platform. Page 7 - X-bit labs

    1866 Pnp ram works fine in the earlier HM models and doesn't clock down. I'm unaware of any changes made in the EM models that would change that.

    Hi ppl,
    I have 16GB HyperX 1866MHz PNP working at 1866Mhz all day on my P150HM so in P150EM I think it will also work just fine.

    Here's some Info+benchmarks:

    So far it was a good purchase.

    So how would one compare 1600mhz with cas latency of 9 to 1866mhz with cas latency of 11?

    Also somewhat related - I assume 4 dimms of 4gb each will perform better than 2dimm of 8gb each, but how much? Thinking about doing the 2x8 with adding another 2x8 down the road in mind.

    TBH The difference should be slim.. a CL9 should be on par with a CL 11.

    Very nice. So JEDEC is all you need to have it run at 1866 :D. +Reppp
    By the way which CPU are you using?

    Is the 1866Mhz RAM supported by HM77 motherboard even if it's downclocked ?

    im jealous that you're kingston's are working. After a few weeks of bsod and thinking it was driver issues, finally testing with prime95 and intel burn in and realizing it was either cpu or memory issue. checked with cpu-id, memory was showing to be running at 13-12-12-32 1866 dual channel. took ram out and replaced with stock rams 9-9-9 1333 ones and ran intel burn in and prime 95 working perfectly now. Just sent kingston e-mail for rma number. hopefully they ship me fast.
