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.

 

Thank u for ur answer...
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?????

 

Yeah...you guys have to stop with the misinformation. XMP in Sandy Bridge plug n play HyperX modules will automatically set it to 1600 or 1866 regardless of what processor you have (assuming it is Sandy Bridge).

 

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.

 

See attached. Stock RAM.

 

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?

 

I believe in the current i7 chipsets you can unlink your RAM and CPU frequencies, thus allowing you to set them somewhat independently (I could be wrong on this; I know in the first-gen i7's you could not, at least not in my i7 920).

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.

 

This man knows his stuff. I was trying to rep you but apparently I already repped you a few days ago so no go. Ha!

 

Okay, that makes sense. Thanks!

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?

 

You are correct about BCLK as pertaining to previous i7 chipsets. I don't have a Sandy Bridge machine so I can't answer that yet. I have read that you can't really adjust the BCLK on non-K (unlocked) CPU's, but I don't know if that pertains to the mobile CPU's as well and I also don't know what overclocking Alienware has allowed through the BIOS.

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.

 

The biggest reason you are seeing a big difference there is because the IGP is staved for bandwidth so the better the ram the better the IGP performs.

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.

 

Umm...you might need serious help.

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.

 

Thank you! That's the point that I'm trying to get across. The original argument against this RAM is that there is no benefit whatsoever. However, there ARE benefits to getting this RAM, as it increases your IGP performance, so you don't need to use GT555M all the time, which equates to power saving. And the new Sandy Bridge quad-core processors do have IGP, so this point is valid.

 

thanks for the posts - i too was looking at this same memory card

 

that's total bull*** what u just said above
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

 

Hi, these are my values






Ciao

 

and even these









Ciao

 

@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

 

I know, I have not done a great deal, for 122 € I have a paltry increase of performance ...... means that when we go out in the HyperX 8GB 2133Mhz kit to take.


Ciao

 

what?? they planning to go even higher??
seriously??
crazy-silly
but i am interested too

 

Kingston has announced the Hyper-X SODIMM 2133MHz has been Intel XMP certified. This is the first and fastest notebook memory to be certified from Intel. The test was performed using a Core i7-2920XM and an ASRock HD65-MXM motherboard. For the test, the RAM timings were set at 9-11-9-27 with the frequency of 2133MHz. This memory will join the current offerings from Kingston for laptop memory, which includes both DDR2 and DDR3 modules. No word on when this will become available to consumers, and the memory has not yet been added to the Kingston website.

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 :

 

goooooooooooood

Am I the only one or is it physically difficult to insert the HyperX 1866 Mhz RAM’s in the slots with the heat shield on?

 

it takes longer to unscrew and remove the base of the m14x, unscrew the panel that covers the 2 ram slots, but to change the old with the new ram. no space problem with the heatsinks HyperX

ciao

 

Yes, they actually seem to be like a 10th of a millimeter to thick.
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?

 

I certainly would like to see this, I imagine the gains might be negligible. Since my RAM runs at 1600MHz already (BTW: M14x i7 2630QM here and it runs 1600Mhz RAM stock) I was interested in the lower latencies of the Hyper X, CL9 compared to CL11. Obviously the 1866Mhz run loose CL11 latencies too, in desktops the performance gains between these frequencies is negligible I would not be surprised if this were the case for notebooks too.

 

Try to see here, and as I said in that forum is not much difference to go from 1600Mhz to 1866Mhz

Ciao

 

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.
