this is an old thread i made > http://forum.notebookreview.com/ali...y-told-me-not-buy-ram-hyperx-8gb-1866mhz.html
in this thread many users told me not to buy the HyperX at 1866MHZ...
"The best processor to date only support up to 1600Mhz. Unless there is no difference in the RAMs pricing there is no point spending extra to get 1866Mhz RAMs" some user told me that...
luckily the HyperX is out of stock everywhere... so i we have more time to decide this:
if i get the HyperX at 1866MHZ will get better performance?????
Order Date: 5/5/2011
Estimated Delivery Date: 5/24/2011
Order Status: In production
just 2 weeks!!!!!! and i will have u in my arms... M14X![]()

No. You won't be getting better performance man. The processors on the m14x only supports up to 1600 mhz. That means even if you get the HyperX (1866mhz) it'll just be downclocked to 1600 mhz depending on which processor you chose. If you chose the 2630qm it'll be 1333 mhz or the 2720qm and 2820qm that would be downclocked to 1600 mhz.

other responses:
"You can set it to 1600 or higher in BIOS. Or with XMP it will auto-set to the fastest speed" > sk3tch
"if you buy either the "Sandy Bridge plug n play" 1600 or 1866 Kingston HyperX RAM, it'll automatically switch to the max capability of the RAM without the need to go into the BIOS (via XMP)" > sk3tch
and what about the review i mentioned 1866MHZ WITH SANDY BRIDGE> Kingston HyperX 8GB 1866MHz PnP Memory Kit For Notebooks - The Test System - Legit Reviews
What do u think about that????? -
-
Then why does Dell say the stuff about the lower CPU underclocking it and in the manual showing all the ways you can set up RAM, and not having 16 GB? Why would Dell say the m11x supports 16 GB but not the m14x?
-
Hey Sk3tch, could you take a screenshot in CPU-z or something to show your memory running at 1600Mhz with the 2630QM? To prove it and to stop the misinformation.

Nice. Thank you.

Part of me wonders if, although running at 1600Mhz, it is only effectively 1333Mhz, because of the processors limitations. I'm not sure why Intel would list the 2630 as only supporting up to 1333 if it supports more.
Have you ran any memory benchmarks at 1333 and 1600 to compare? -

Also, even with the CPU and RAM frequencies being linked, you can easily modestly overclock the CPU and easily get the RAM from 1333 to 1600. That goes for any of these CPU's by the way.
Fast memory like this is largely a waste of money. You will see essentially no performance gain going from 1333 to 1600 MHz for example. The ONLY real benefit of using expensive/fast memory with current chipsets is if you plan on overclocking the CPU (and thus overclocking the RAM by default if the frequencies are linked or dependent on the same base/multiplier). Outside of that, you need only buy RAM which can run at the native/stock clock rate as dictated by the chipset and CPU frequency. -
-
But I thought you couldn't overclock the BCLK on sandy bridge processors? Isn't that what you would have to increase to increase the RAM frequency too? -

I'll start another thread to gather info about CPU/Memory overclocking in the BIOS to see what Alienware has allowed. They did repeatedly promise that everything can be overclocked, which is contradicted by everything I've read about these CPU's which says they can't be overclocked substantially. -
See, I would agree with you if it's not for this thread:

If you can provide an alternative explanation as to why the 1866mhz RAM makes such a big difference, I'm willing to listen.
-
With the discrete card you will not notice this big difference. I have upgraded to 1866Mhz HyperX and while my WEI jumped up from 7.6 to 7.9 but that might be from jumping from 4Gb to 8Gb. -
Kingston HyperX 8GB 1866MHz PnP Memory Kit For Notebooks - H.A.W.X. 2 Benchmark - Legit Reviews
Whomever wrote this benchmark needs serious help. Their is absolutely no way that a memory speed nets you 15 fps. I doubt even 3. Usually it's less than 1 percent. Please don't believe this mess. The folks at techinferno also started running benchmarks and absolutely no difference in frames in metro2033 at 1366x768 at high performance levels (dx11) between 1067, 1333 and 1600.. So... dont believe the hype.
If you do believe this I have a magic sticker you can apply to the bottom of your notebook that will provide a 200 mhz increase. -
The reason it is such a huge difference is because they weren't using a dedicated graphics card. They were using the sandy bridge IGP which uses the system RAM. And we all know memory bandwidth is important for GPUs. -

thanks for the posts - i too was looking at this same memory card
-
I have purchased these RAM and I have HUGE performance improvement ! -
Here is MAXXMEM

here is cmd windows 7 benchmark

Does higher memory performance means shorter total run time?Cuz on my X58 platform my performance is 14924.16MB/s,while the total run time is only 7:08.
My RAM:6X1GB 1066MHz -

@NforceRaid
haha similar to mine -
I just purchased 2820 i7 so once i replace cpu results will be higher
But these results are limited to your HDD or SSD anyway so unles u have best SSD SATA 6 but even that wont be equal to RAM ram will be still waiting for drive -
Ciao -
seriously??
crazy-silly
but i am interested too -
we just have to wait for the 8gb kit.
Hi -
@nforceraid
which includes both DDR2 and DDR3 modules
they DEFO wont be using this speed on DDR2 modules that's impossible
they cannot carry such speed no defo not! -
@NforceRaid
Hi I just upgraded the processor and results are following :Attached Files:

Am I the only one or is it physically difficult to insert the HyperX 1866 Mhz RAMs in the slots with the heat shield on?
-
ciao -
could be that this is just a problem with certain batches of the RAM vs. certain batches of the M14X motherboard (Upper end of tolerances on the one and lower end of tolerances on the other one).
The first goes in fine anyway and with the second you should be fine to push it down as far as possible and then "manually" make the side clips snap on the second one.
Not ideal but works.
I also recall some other ppl complaining about the same thing, btw. -
Are there any benchmarks of the 1600 Hyper X PnP vs. the 1866 Hyper X PnP? Is it really worth the $40 price difference?

Is there a point to install hyperx 1600 8gb when the system has 8gb std dell 1600 mhz ram? i have the sticks lying around.
