Fastest DDR4 rams for notebooks

hello , im gonna buy the new alienware 17 and the fastest ram they offer is 2667mhz so i was wondering should i buy rams from amazon ? coz either way im gonna pay hell alot of money for the laptop and i want the best thing in my laptop so does any of u know about this stuff coz im kind of a noob i dont know about latency i just know the speed is important in games and i know its not important by alot but i just want the best thing i'd appreciate if someone helps me with this decision

You can swap the RAM on your own as long as you know how to teardown the whole machine but if not then you better buy it already installed.

You should hold out on buying faster ram until you have the machine in your hands. Chances are Alienware will gimp the bios so you can't run 3000mhz ram.

This is what I had in the P870DM-G and it was excellent.

G.SKILL Ripjaws Series 32GB (2 x 16G) 260-Pin DDR4 SO-DIMM DDR4 3000 (PC4 24000) Laptop Memory Model F4-3000C16D-32GRS

Haven't tried this, but it's probably decent as well.

CORSAIR Vengeance Performance 32GB (2 x 16G) 260-Pin DDR4 SO-DIMM DDR4 3000 (PC4 24000) Memory (Notebook Memory) Model CMSX32GX4M2A3000C16

 

Anything less than 80usd that's 2x8gb and decent?

 

This is $74.99... and, if the machine has a decent BIOS can probably be overclocked to 2800 without too much effort. The Kingston HyperX 2400 has no problem running at 2800.

CORSAIR Vengeance Performance 16GB (2 x 8G) 260-Pin DDR4 SO-DIMM DDR4 2400 (PC4 19200) Notebook Memory Model CMSX16GX4M2A2400C1

 

How about in the P870DM3 with prema bios?

 

I don't have one yet. Maybe around the end of the month. Will have to wait and see how that plays out. If that happens I will go with 2x16B DDR4-3000.

 

I've heard the BIOS is meant to support 3000hz out of the box. I've noticed most resellers only offering 2800mz though. We'll see soon.

 

@Johnksss@iBUYPOWER has DDR4-3000 G.SKILL is his DM3.

 

Awesome! Good news.

 

so do u recommend that i buy those g.skill 3000 over the 2667 that alienware r offering ?

 

I am unable to recommend that because I don't have any idea whether or not Alienware supports 3000. Considering how they have been crippling everything they sell for the past couple of years, including their desktop computers, it's anyone's guess whether it will even boot with the 3000MHz XMP profile.

However, yes... I would suggest getting the cheapest memory (and drives) that they offer and buying your own aftermarket upgrades. You can probably get 2666 RAM from Amazon or NewEgg for half what they will charge you for it, and it will carry a lifetime warranty. Getting RAM and SSDs from Alienware (and many other OEMs) has almost always been a bad idea due to price gouging. Alienware is also notorious for using proprietary firmware on their drives, so you generally won't get important SSD firmware updates like you will going aftermarket.

Just be sure to hang onto the original RAM and drives in case you need to return the product for a refund or send it into the Dell depot for repair. Even for remote diagnostics some of their tech support muppets will refuse to do any troubleshooting with aftermarket parts installed. Some will, some won't... depends on whether you end up talking with Big Bird, Kermit, Miss Piggy, Cookie Monster, Mr. Snuffleupagus, Grover, Ernie or Bert.

 

i need ur help with something i have found 3000mhz ram and 2666mhz the weird thing is the 2666mhz is more expensive than 3000mhz why is that and it says 2400MT/s what does that mean and here r the links

Just to give you a bit of experience from the 15R2 - it probably won't work.

I made the move to upgrade to 32Gb recently, and found that 2400Mhz was a crap-shot. At 16GB it would boot and function most of the time, but only with one stick. Anything else, it was unstable. At 32Gb, it wouldn't even try. I have to run at 2133Mhz to keep this machine working. Also, with the newer BIOS revisions (which is required for 32GB apparently), they removed the option to modify the ram clocks at all.

 

MT/s is megatransfers per second and refers to the number of data transfers that occur in one second.

Here is the same DDR4-3000 RAM for substantially less. http://www.newegg.com/Product/Product.aspx?Item=N82E16820236068

Assuming compatibility with the system you would plan to install it in, the DD4-3000 is better/faster than 2666 simply because it is overclocked higher. If the machine you plan to use it in does not support it, it might still be bootable at a lower speed. There is also the possibility it would not be bootable. The only way to find out is to try it. The 2666, 2800 or 3000 clock speed is generally applied through an XMP profile and the default SPD profile is something less, such as 2400.

 

Well the new one supports up to 2666mhz so even If I bought these from amazon it will save me alot of money I think ,, not to mention they dont offer 2666mhz in 32gb only in 16gb which is weird so I think im gonna try the 2666mhz in amazon

 

Do u think this corsair rams 32gb 3000mhz can lower its spd to function on the supported spd of the laptop ?

 

As I mentioned, the default SPD speed in most cases is 2400 with 2666, 2800 or 3000 supported in an XMP profile. Short answer to your questions is 'probably' but the only way to know if it will work is to try it and find out. Whether it will or not will be dependent on the amount of effort the OEM puts into getting the BIOS right. If you are considering putting it into an Alienware then the chances of it functioning correctly might be slimmer because they generally don't support anything special and tend to gimp things a bit.

 

The ram usually doesn't mind being clocked slower than rated, but you should make sure your machine will let you do that first. As I said, that feature was removed from some Alienware machines.

The machines I own all tend to use the highest available/supported clock speeds. Even when they don't work.

 

Do you think how likely Sager NP9876 (Clevo P870KM-G) supports RAMs higher than 2400Mhz? Say 3000Mhz? And how far do you think mine can go beyond? In your signature it seems like you got a similar model and overclocked the RAM to 3200? Would you mind advising how you managed it? Thx.

 

Hello. This is only possible using manual timings and XMP profiles with @Prema BIOS. I am pretty sure you are not going to get anywhere with the stock BIOS.

This is DDR4-3333 on my EVOC P870DM3.

 

So you are saying it'll stick to the default 2400Mhz with the stock BIOS, correct? Looks like the latest Prema for P870KM-G is not out yet lol

 

That is correct for now. I will talk to @Prema about what the plans are for the KM1. Maybe I can get an empty shell from the Partner Group and move my DM3 guts into it for assisting with the BIOS mod for the new model.

 

I just noticed, and I should've done it earlier, HIDevolution has been offering KM1 with Prema Bios since it was first released:
http://www.hidevolution.com/evoc-p870km1-dual-gtx-1080.html
Not sure if it's only available for Prema partners

 

It will be available. @Prema does not have it ready yet as far as I know. But, yes to your last question. Prema BIOS is generally only available to customers of Prema Partners. It is not available for download and flashing by the general public. There is a good selection of Prema Partner shops and that list is growing. Anyone with a lick of good sense can see the value in being a Prema Partner, or buying from a Prema Partner. The stock cancer BIOSes on all laptops in today's world is an absolutely pathetic and cruel joke.

Brother @Donald@HIDevolution can clarify if this is correct or not, but I believe so.

 

Guess I'll have to stick to the "cancer" forever as mine was purchased from a non-Prema partner. But thanks for the info anyway

 

You're welcome.

Yes, the situation is a truly sad and pathetic one. I do not believe there is even one notebook ODM in the whole world that does things right with firmware. If I could not have an unlocked BIOS and firmware without restrictions to features there is not any notebook that I would consider purchasing... not even one.

 

According to @Meaker@Sager:

Seems like 3000Mhz is doable with stock bios. Sounds like a good news to me

If they are making it possible now, then yes... fantastic news. If they were really smart they would hire @Prema on a permanent retainer and every Clevo sold would have his BIOS mods and he would be taken care of financially by using his God-given talent to be a blessing to everyone. There is really no excuse for any computer to be sold with castrated firmware. That is an indicator of laziness and paranoia that every ODM is guilty of.

 

Hi Mr Fox,
For my p870dm3 i own the 3000Mhz and working great, but i heard that will be released the 3200Mhz, it is true?

 

Only if 3200 RAM is available. It is very difficult to find, and unless that changes first it will not happen. So far, the only brand I have seen is G.SKILL Ripjaws and it is difficult to find. I have 64GB of G.SKILL 3200 in my DM3 right now. It is difficult for some machines to run it stable. Some have difficulty running 3000 stable, so if your machine is taking to is smoothly, count yourself among the fortunate. Mine is mostly stable at 3200, but not 100% 24/7. I still get a memory-related BSOD now and then with it running at the 3200 speed it is rated for. It normally happens doing something ridiculously mundance, like watching a YouTube video. And, that is using custom settings and increased voltage. If I use the G.SKILL default values in the XMP 3200 profile with the default 1.200V it is far less stable. And, it makes hardly any measurable difference in performance. Only memory specific benchmarks show much improvement in performance. Other benchmarks and games don't really benefit from 3200 over 3000. The difference is within a normal margin of error for two machines running the same memory.

 

So better to stay with mine, i hope they will release a new version more stable on it.
Thanks for the answer Mr Fox
