m18xR1 - reliable 2133mhz+ ram?

what's the most reliable way to get 2133mhz+ ram for the m18xR1, i read good things about Kingston HyperX RAM....looking for 16gb

by reliable i mean plug and play no flashing RAM bios, no manual overclocking etc.

 

Only known way to get 2133MHz RAM is to use Kingston HyperX, and set up an XMP profile for it to run at 2133MHz

 

so Corsair Vengeance 2133mhz won't run at that spec?

 

This is what I use in the M18xR1 and it does not require any kind of tweaking or XMP profiles... plug and play 2133...

The M18xR1 was hit or miss with Corsair Vengeance DDR3 1.5V RAM. I have this DDR3L 1.35V RAM in the M18xR2, but I have never tested it in the R1 motherboard...

...it may work fine, but I cannot tell you for certain that it will. Go with the Kingston and you should have no issues at all.

 

Ram should be your last upgrade especially in terms of speed as it has the least impact on performance.

 

Agree... makes very little difference in the grand scheme of things, but this fella is going all out with XM and 780M upgrades for his R1. So, the RAM will have a fitting home in a maxed out R1.

 

Ah then there is the new impact 8gb modules rated at 2133mhz.

 

im feeling really retarded right now i bought the 1866mhz 16gb kit and just realized the 2133mhz kits are selling at pretty much the same price

wow

EDIT: before i rip this ram out and buy the 2133 can i just get a final confirm that it will run at 2133mhz PnP on an m18xR1 ?

EDIT2: i'd also be fine with burning ~2000mhz settings onto the sticks instead if that's a go

 

Which ram did you buy? Corsair? 1866 or 2133? If its the 1866 you will have to do what I did for the ram ( My Thread on Corsair ). If you bought HyperX I believe Mr. Fox's dump is still on there for 2133mhz. Also when running the higher clocks you have to pretty much max the voltage of the ram to make it more stable, doesn't really run any hotter so it shouldn't bother it. If you run into any questions, pm either myself or Mr. Fox on how to use Thaiphoon Burner.

 

Looks like he took your advice

 

I have an m18x R2, i7 3940xm, 680m SLI and currently running stock 8GB of 1600 RAM My RAM usage is way up and really need to upgrade to 16GB G.Skill Ripjaws are priced right and the 1600, 1866, and the 2133 are within a few dollars of another. Has anyone tried or hand any trouble with these? Here is the link: http://www.newegg.com/Product/Product.aspx?Item=N82E16820231752

Also on a side note: I have a Samsung 840 pro that used to have a rating of 7.9 on the window index but now reads 5.9. The other thing is that it is running at 3.0 ghz and I need more power. Can someone send me a link for overclocking the 3940xm in the m18x R2? I dont need inane number, just faster but till reliable.

Thank you

 

i believe i remember mx fox posting something about the Gskill being slower than the Hyperx by a noticeable amount

 

Most people are going to be better off with a decent 1866mhz kit since that will offer the performance and compatibility.

 

I just (today) got the problem with the Alienware 18 not running at 2133 solved.

See post here: *OFFICIAL* Alienware M18xR1/R2/18 Benchmark Thread - Part 3

 

Hello there.

I've found some interesting solutions in this forum so I decided to create an account to directly ask some questions.

I have an Alienware M18X R1 with 8 GB 1600 MHz DDR3 SO-DIMM RAM (4 x 2048 MB PC3-12800 Nanya Techology) and use it for computational simulations for civil and mechanical engineering research in Brazil in partnership with some American Universities' Doctoral Programme, as MIT and University of California (Berkeley), and, of course, for gaming in free time! Recently, I noticed it became slower than some years ago. I'm not completly sure if its because the development of our simulations, because the long time without reformating or other possibilities. But by this and other facts, I'd like to upgrade my RAM to at least 16 GB.

I've read many posts from Mr. Johnksss, Mr. Fox and Mr. Codenamefa within this forum and observed some interesting solutions for overclocking memory RAM. I've also noticed some models listed in the posts. The problem is that here in Brazil we have much dalayed models and the costs are about 4 times more expensive then in USA. Unfortunately, I won't be able to visit USA soon. For these reasons, I couldn't find most models listed in posts here. But, I found a Corsair Vengeance 16 GB (2 x 8 GB) 1600 MHz, a HyperX 16 GB (2 x 8 GB) 1600 MHz and a Ripjaws 16 GB 1866 MHz all with 1.35 V (DDR3L Low Voltage) for sale. Also found a HyperX Impact HX321LS11IBK2/16 16 GB (2 x 8 GB) 2133 MHz (lucky).

I've also found some posts from Alienware technicians on the web saying that the maximum native memory supported by M18X R1 was 1600 MHz while others said it is 1866 MHz at maximum, which made me confused.

My questions are:

1) Is there any problem to use low voltage DDR3L RAMs (1.35 V) in M18X R1 as it uses 1.5 V, for normal and for overclocking purpose (As pointed by Mr. Fox)?

2) To eliminate this doubt definitively, as many posts were contradictory, can the M18X R1 support natively (without overclocking) 1866 MHz and 2133 MHz RAM frequencies, or it can just work natively with the maximum of 1600 MHz and overclock to 1866 MHz and 2133 MHz?

3) For the described models, which one do you suggest?

Thank you very much in Advance!

 

Anyone?

 

The M18xR1 and R2 are way different in some respects, not so much in others. The 18 is yet further different and all three vastly different with respect to how they handle memory due to the different chipsets. The posts you read may not be contradictory as much as reflecting individual experiences (which can vary widely) and lack of clarity. Unfortunately, I find it rather pathetic that so many people don't even know how to accurately identify the model name of their machine. It is very difficult for me to understand that. This being the case, you have to question the relevance of some of what it posted. All over the board... M18, 18X, M18xR3, 18r2, 18XR2, blah, blah, blah. It is really sad that some people have no clue how to accurately identify what they spend a butt-load of money on.

For the record, I have been running Kingston HyperX PnP 2133 in the M18xR1 for like 3 or 4 years now. It works great. The BIOS is very limited in terms of available custom memory settings on the M18xR1. They don't go high enough. As a consequence, whatever the BIOS decides to assign for timings you are pretty much stuck with, like it or not. The HyperX PnP runs at CL13-13-13-36 CR2. None of those settings exist in the BIOS.

This HyperX PnP 2133 is not low voltage RAM. If I use my Corsair Vengeance DDR3L-2133 from my M18xR2 in the M18xR1 it will not run any higher than 1866. It works great, but refuses to run at 2133 not matter what I tweak in terms of settings. I think the BIOS is unable to assign timings that work for the Corsair Vengeance at 2133, so it drops to 1866 with timings that work fine.

Hope that helps. If you want a proven experience at 2133 then go with the HyperX PnP and be done with it. Don't get too hung up on timings. I won't say they are irreleveant, but not they're not far from it. The clock speed increase provides more benefit than timings and neither one is provides a remarkable experience change over DDR3-1600. Very minor change in performance in the grand scheme of things... very measurable, but nothing massive, in benchmarks and virtually imperceptible in games and normal use.

Biggest boost is bragging rights, and who doesn't like those? Right? Let's be honest... we all like that the most. I love that my Panther (Clevo P570WM) is clocking the RAM at DDR3-2400, but I can't feel anything, LOL.

 

i used Typhoon Burner to change my HyperX from 1866 to 2133, mostly because i bought the wrong one by mistake, and it's worked flawlessly since then, M18XR1 w/ modded BIOS
