M18x Memory Discussion Thread

2133MHz notebook RAM may be available in the near future, but if the 1600/1866 experience is anything to go by, you can count on it being sky high in terms of price, limited in availability, and not much of an increase in anything for what you're paying.

My guess would be that 2133MHz RAM won't be of much benefit anyway until the Ivy Bridge generation of chips is out, but even then it is still going to be some pricey stuff, and 1600/1866 might be the better deal similar to what 1333 is now. It might be worth it for those who want to throw hundreds of dollar or more at such an 'upgrade' for a 'possible' performance increase that isn't even noticable, except perhaps on the most memory-intensive of applications.

I'm more curious about DDR4. That should be a noticable upgrade.

 

yeah DDR4 or lower timings but we are going to need new computers lol

 

Hi can someone tell me and give me a link to the best and fasted ram upgrade for an m18x? im looking for 8 gigs in all, pref 2 4 gigs. thanks!

 

You surely cannot go wrong with Kingston HyperX! Max supported memory type for your CPU is 1600Mhz, so you may want to get HyperX 1600Mhz.

 

so 1866 Mhz is not supported? what cpu does support that?

 

The frequency we are talking here is speed at which memory communicates with the CPU. By default 1600Mhz is max for 2920xm. You can use 1866 dies, but still CPU and Mem will talk at 1600Mhz.

 

so what youre saying is it is completely pointless to buy the 1866 hyperx?

 

You can't tell the different in real time But there is some fps increase.

I was playing league of legend , it was 380+fps max , after I slotted hyperx 1866ram its up to 411+ fps.

Even tested in Resident Evil 5 , was tested with average 168.8fps , with hyperX 1866 ram increased the fps average of 179.7fps. Basically it increase 5% fps.

Also 2920 support up to 2133mhz ram in bios setting.

PS : Personal experience 1866mhz (2x4GB + 2x2GB) 12GB HyperX. Forgot to mention , its HyperX PnP Ram (Grey Colour , you don't have to set anything in bios)

 

Is this in comparison to the older dell stock of 1333 mhz?

 

Yes. 12GB 1333mhz (2x4GB + 2x2GB)

 

Kingston HyperX 8gb DDR3 1866

 

Cool, thanks. And what exactly is the setting that has to be changed in the BIOS if 1866 ram is installed? Or maybe I'm oblivious to other threads that have the answer lol

 

That ram is plug n play. It's automatic. Install it and boot up the computer. Enjoy.

 

True, but what if it wasn't? I'd just like to know for general knowledge, if you don't mind

 

It's under the advanced tab in the bios. The same screen that you use to overclock your cpu. Scroll all the way to the bottom.

 

iPhantomhives, how do you know these 5% isn't just the 1333-1600 difference there? If the CPU and mem can talk faster, there is obviously the difference there, and that's along the 1333 vs. 1600 line. Did you make the tests yourself? Can you document them? To properly document 1866 performance measure the difference between 1333 and 1600 first.

For 1866 vs 1600, the only faster thing for 1866 RAM is in-between memory dies data transfer. It will show a memory speed increase in some memory benchmarks, yet in the RL any gain related to RAM dies talking to each other at faster speed while CPU still talks to memory at 1600 will be pretty much unnoticeable and surely won't lead to a 5% fps increase.

We are creating a 1866 myth here, just a bit, you know, aren't we?

 

Faster ram definitely shines in synthetic benchmarks and physics tests. I believe you need the 1866 or higher to have a 7.9 memory WEI on the M18x as well. I have a 7.8 with my 1600 HyperX.

As expected, 1333 vs 1866 tests, so as said above.

 

here is the test from kingston blog.

Kingston Blog

 

Can the 2720qm support the 1866mhz ram?

 

All mobile Sandy Bridge chips state the maximum supported memory is 1600. You will still be able to take advantage and notice a very minor difference with the 1866 and 2133 ram have a higher memory bandwidth. 25.6Gb/s Maximum Supported Memory Bandwidth for the 2720qm

 

This "test" isn't for real, is it?

 

Does the standard 8 gigs install under the back plate or would replacing the first 8 gigs require getting under the keyboard? I want to rock 8 gigs, but really don't want to go under the keyboard.

 

Usually they install under the back plate.

 

So this is the ram that I got. All I need to do is just install and it ready to go or do I need to go into my bios setting and change somthing? I have the 2720qm cpu. Thank!!!

You won't have to mess with the bios. Just plug n play

 

Is it really worth $150 to go from 16GB 1333 to 16GB 1600?

Try pm Villosa , you might get some discount.

If you are not planning to "bench" your machine , heavy video/graphic edit or heavy multitasking , its not necessary.

 

Hi Iphantomhives,

Do you mean that the M18x can take those:
KHX2133C9AD3T1FK4/8GX T1 W/Fan Intel X.M.P, DDR3-2133MHz, Non-ECC, Unbuffered DIMM ( 4 - 2GB @ 9-11-9-27 - 1.65V ) w/ HyperX fan
???

 

I just ordered 8 gigs of 1866. Any reason to go from 8 to 12 or 16? I have a few bucks to spare, so I am just wondering if I should make the plunge or not.

 

In general it seems that more memory is better than just faster memory, at least for the money, if you don't need the speed for benchmarking.

So, 8-16GB of 1333MHz for under $100 is probably all most people really need. 1600MHz stuff, especially like the HyperX, is great, but at twice the price, not really twice the improvement.

But the 1600-1866MHz is still a worthy upgrade in terms of using the capability of the CPU/Memory. Even if it's not exactly cheap, 16GB of 1600/1866MHz is still a deal compared to what 32GB of 1333MHz costs at the moment.

 

Thanks for the heads up. I will probably go ahead and pick up the last 8 gigs because if I don't spend it, my wife will. Now to test my nerve. I never really had the stomach to get under the keyboard of my M17x, so the 18x is even more of a gut wrench.

 

I did not have any problem installing kingston 1866Mhz into my 17R3. I will tell when I'll recieve the 18x. I guess it will be the same, "Plug & Play" ^^!

 

I believe those are desktop rams...

but here is the right ones. Intel® Core? i7 Mobile Processor Memory Supplier List

Kingston HyperX 2133mhz SO-DIMMs get Intel XMP certified

From what I mention was, there is 1333 , 1600 , 1866 & 2133 in our bios setting.(I can provide you screenshot later , my beast is not with me)

 

Hi just installed 16gb 1866 hyper x on my system , bandwith according to sis sandra is 24.5 gb and currently running it at 974 mhz x2 and no probs , got me over the 8k on 3dmark11 with my 2720qm and ati 6990, no adjustments in bios only the fsb , not sure if this helps anyone but there it is .

 

If only the 2133mhz ram was out as 8gig sticks! Then I would buy 32gigs

 

Me too , but the 1333 with 8gb itself already overprice
Newegg.com - Patriot Signature 8GB 204-Pin DDR3 SO-DIMM DDR3 1333 (PC3 10600) Laptop Memory Model PSD38G13332S

 

32GB of 2133MHz would probably cost more than the rig you're putting it in.

Kinda nice the M18x has the capacity for future upgrades if/when the larger sticks ever get more common and less expensive. I suspect it'll be outdated by then, though. Besides, 32GB is just for bragging rights, 16GB is doable, economical, and still excessive, at least for now.

 

Any suggestions for what the best ram is for the 2760, and the cheapest place to buy online?

 

Newegg.com - ADATA XPG Gaming Series 8GB (2 x 4GB) 204-Pin DDR3 SO-DIMM DDR3 1600 (PC3 12800) Laptop Memory Model AXDS1600GC4G9-2

Hands down the best thing available for the price right now.

 

Damn thats cheap. I hope they deliver to the UK. So it has to be a 204 pin dual channel?

 

Doesn't have to be dual channel but that's what you want. Dual channel just means you are running two of the same sticks for increased bandwidth rather then just one stick. It does have to be 204 pin though if you want it to work

 

That is 1.35V RAM not 1.5V RAM. Is that compatible?
(Actually I am really asking re the M14X... user manual does not mention voltage supported)

 

I bought 8 Gb 1600 Mhz kit at Frys for $40.00 and it came with a $10.00 rebate. Installed it and worked wonderfully.

 

All I can say is it has been working great in my 18x for a few weeks now.

 

Hi,

I just got my m18x stock customize with 4Gb ( to expensive to upgrade from alienware )

Now I want to uapgrade my RAM, pls tell me where can i get cheap RAM, and pls give me the link.

Also pls tell me instruction to upgrade RAM (i'm newbie at laptop )

thanks

 

1. Buy RAM from here http://www.newegg.com/Product/Produ...0006178 600000410 600006157&IsNodeId=1&name=9
2. Watch this video to replace the RAM at the two slots below the M18X http://www.youtube.com/watch?v=NhURMyavgks
3. Try this guide http://forum.notebookreview.com/alienware-m18x/583324-ram-upgrade-m18x-pics.html

I would suggest the ADATA ones if you are on a low budget or the Kingston Hyper X if you are on a high budget.

Enjoy the machine

 

I have the Kingston kit and it has never let me down. The isntall is fairly simple

 

I agree with rahulkadukar... step 3 worked perfect for me. It was easy and I bought ram at frys. 8 Gb 1600 mhz kit for $40 with a $10 rebate.
