[Confirmed RAM List + Feedback] - Alienware 17 R4 / 15 R3

Where to get a computer like this?

Cool... My next investment

 

Just be sure you buy one from a @Prema partner shop so you are eligible for fully unlocked BIOS and high performance vBIOS, all covered under warranty. If you buy it somewhere else, you won't get that.

 

Confirmed the G.SKILL Ripjaws Series 32GB (2 x 16G) 260-Pin DDR4 SO-DIMM DDR4 2800 (PC4 22400) Laptop Memory Model F4-2800C18D-32GRS works in the R4

speed? 1400mhz x 2? Cl 18 es mucho

 

I wonder if it will handle the G.SKILL 3200 RAM?

 

I do not think AW 17 R4 supports 1.35 v

 

Maybe ask for it in the AW social media. Ask for a less gimped firmware so you all can use whatsoever ram sticks and speed. Or maybe they want you all to buy ram sticks on Dell's website.

 

I am very disappointed with dell. Today they came to replace the cpu fan. But he is sold to the heatsink.
Now, i have to wait for the correct part (heatsinks + cpu/gpu fans) to be sent from the Dell US. 15 more days of waiting.

 

And you like all other have paid(inclusive in the purchase for 1 year) for the day after Support. Oh'well, time have changed.

 

I see you were completely ignored in this thread. Did you end up buying one of these? I'm in the same boat!

I think the Crucial Stick is likely the right choice being that it has a similar CAS latency (CL17).

 

I had bought 2 HyperX Impact 16GB rams with a speed of 2400 and latency of 14.

Theoretically, they should be one of the fastest currently available due to their extremely low latency

Also at the time when I got it 3 months ago, it was $50 cheaper also

I also chose this RAM, they're pretty much all reliable nowadays and since laptop RAM can't be overclocked (if anyone knows how to do so let me know), stock timings is what matters here and these HyperX have the best timings-to-speed. The price is either slightly higher or equal to "faster" (higher speed, much higher timings) RAM. After I bought mine the price went up 30$ too, seems its only up 25$ now

 

Do you think this will work with the GTX 1080 model with the 6820HK ?
Corsair Vengeance 32GB DDR4 SO-DIMM K2 3000 C16 (CMSX32GX4M2A3000C16)

 

I can't believe latency really matters all that much at these speeds. I remember reading a pretty in depth review that overall speed trumps latency concerns. I need to find a link. I'm not even sure that going to 16GB provides a tangible performance benefit, because I've seen those articles. I'm not even sure that going dual channel over single channel provides any significant advantage (at least in gaming). But, I'm open to other opinions.

 

I remember looking into this myself a lot during 4790K days and DDR3. From what I remember, 2333Mhz RAM was the sweet spot for gaming. It provided the best and most consistent FPS in videogames, I could only assume due to the speed+timings. It might have only been compared up to around 2800-3200RAM though, now DDR4 goes up past the 4000s.

As for the 8GB vs 16GB, 8GB was good enough up until recently. Now with games, they start to use about 4-6GB maxed out. Could be more, could be less depending on the games and settings. But now we have programs running in the background too. 16GB seems like it should be the new "norm" starting in 2017 for 1080/1440 or higher. I use 1080 screens but I love DSR

 

The timing (ns) is a product of both speed and latency. From that point of view, this has the best results since all the higher speed RAMs have a higher ns. The difference might be very small but when the higher speed ones are more expensive, it's not worth spending on them.

There is a higher speed Impact RAM with low latency but it's only available as 8GB cards

In your guys opinion, if I buy an additonal CL17 stick of Crucial RAM to complement the Hynix CL17 ram inside my AW13 R3 - would that be a good match? I know it's not optimal, but I'd really like to save spending 75 more bucks to get 2x8GB and throwing away the internal stick. If I spend more than 100 bucks, I might as well have bought the 16GB upgrade straight from Dell's website since going form the stock 8GB stick to 16GB was a 100 dollar upgrade.

Better question might be, does anyone have an 8GB stick of ram they pulled from their Dell laying around they would sell to me. A matching stick would be awesome!

 

Yep! I bought it and it worked. here is my short review of the laptop:

 

Difference if you bought the 16GB would be that you had 8GB laying around to sell for 30-40$ easily AND then you'd have high quality lifetime warranty DDR4 RAM. Though when sending it in for repairs, I would never advise to leave the aftermarket RAM in there, it'll probably disappear

 

So what is the final verdict on supported ram? @iunlock

 

Most of the timings on the higher speed RAM's are terrible. I've just stayed with the stock 32GB SKHynix 2400MHz....the timings are good and SKHynix is a trusted chip.

What type of work are you doing for the need of faster RAM? Just curious.

 

But you can fix the *terrible* timings. Have you seen in the Clevo OC thread? +3200MHz now.

 

Nothing much. I just wanted to get the best. I know the Clevo's run 3200mhz on the latest one. Curious if anyone has tested them on the AW.

 

Yea that's impressive.

 

aloha

 

Aloha!

 

I bet that if you mix one stick of the old ones with one of the new ones the system will boot and work without problem.

I'm suffering a similar issue with another model of Dell laptop (precision 7510) that I reported here: http://forum.notebookreview.com/thr...c-stick-only-boots-if-you-mix-the-ram.801052/

 

Is it possible to have the ddr4 running at 3000+MHz on the latest AW laptops? Or is the speed capped at 2667?

 

So far we're capped at 2667 on the latest AW's so these may be the best 2400 w/ Cas14:
https://www.newegg.com/Product/Product.aspx?Item=N82E16820104667

While the next best at 2667 are the G.Skill, but with a Cas Lat of 18. Ouch. I'd say the one above is much better in this scenario.
https://www.newegg.com/Product/Product.aspx?Item=N82E16820104667

I think going with the 2400 w/ the Cas Lat of 14 is the better bet since XMP's can't be altered.

It's capped at 2667. I've tried to put some 3000 sticks in the 17R4 and no go...just runs at what it's capped at.


.

 

What do you modify the timings with?

 

The HyperX RAM is overall a better product. I can overclock my Impact 2400 to 3000 without a problem and they are more stable than the G.SKILL. The only reason I am not using it now is my HyperX RAM kit is 16GB (4*4GB) and my G.SKILL kits are 64GB and 32GB (16GB sticks). The G.SKILL can also run with lower CL without an issue. They made their RAM timings as loose as a goose for some strange reason. Other than the silly 2667 cap, are the individual timings adjustable, or did they lock that as well?

 

Unfortunately, it is locked. The only sure thing that we know is that the newer systems, rather bios, can support 2667.

When I had tried putting in the 3000 in the Skylake 17R4 for giggles, it only read to 2400.

If I put those same sticks in the Kaby Lake 17R4, it will read 2667.

Between the two RAM's that I've liked, in this unfortunate scenario with things being locked, would you opt for the:

HyperX 2400 @ Cas 14

or

G.Skill 2667 @ Cas 18

As for benching the higher speed would be more beneficial? Or would the high Cas of 18 wash it out to give the 2400 @ Cas 14 an edge?

If there are any other RAM options that I may be overlooking, please do share..


Thanks.

The higher speeds definitely improve benchmark scores. So does having 32GB or more of RAM even when not even half of that is used. I'm not sure why the latter is true.

Since there is not much difference between 2400 and 2667, one would have to run the benchmarks to see if 2400 @ CL14 is faster than 2667 @ CL18. Theoretically speaking, they would likely be about the same or maybe even CL14 could give a slight edge, but the only reliable way to know is to actually test and see.

In all cases the differences, even in benchmark scores, are modest. The only benchmarks that really show a remarkable difference are memory benchmarks. Much like SATA SSD versus NVMe SSD... amazing benchmarks, but essentially no perceivable difference in almost anything else. And, when it is perceivable, modest enough that you could miss it if not paying close attention.

 

Very well and great explanation. I had a feeling that it would be about a wash. Hmm...I guess this is one of those that is literally a flip of a coin eh?

 

From what I have read from @D2 Ultima Should 2400MHz ram sticks with a lot lower timings be a better choice than 2667MHz CL18 ram sticks. Isn't the 2667MHz sticks Dellienware use +19 or even CL20?
And max Dell offer is 2x8GB sticks. And the price, Nice

 

Probably pagefile. Since I set my Pagefile to 32GB I experience zero slowdown even if I use up 20GB of RAM on a 7-day-old uptime. But with a smaller pagefile, the more RAM you have the easier it seems to be on the system, and above 50% usage can cause notice-able slowdown to some people.

2400MHz 14-14-14-36 sticks from Kingston are a better choice than 2666MHz 18-18-18-43 sticks from Corsair and G.Skill.

Either you use 3000MHz 16-18-18-43 (and tune it a bit) or you use 2400MHz 14-14-14-36 and leave it. There's no other point to any other existing bit of RAM in the mobile market anymore. Period.

As for the 2666MHz limit on the AW17 R4... can you get your hands on a P6x0HS anywhere? I... want to know if there is also this 2666MHz limit there. If Prema mod is out that would be exceptional too.

See the GT73VR has it, even on the Kaby Lake model. Kaby Lake * IS* lower voltages, higher OC, significantly stronger IMC. Kaby Lake chipset * IS* stronger MC, more PCI/e chipset lanes. End of. I find it weird that the premiere mobile CPU units cannot go beyond 2666MHz. I am wondering if it's BGAtel's glorious foresight that prevents them from using faster RAM because mobile chipsets because they hate laptops just like nVidrosoft.

 

at least with msi machine you can pay svet for the mod to unlock full bios

 

The newer MSIBOOK BGA models with Kaby can't manage faster ram than 2400MHz. Probably the gaming book brand with most crippled ram options.

 

They boot 2666 last I heard. But that is still pitifully slow

If you say it I can remember. But you can't tweak and change to better timings? Could you do that with the former Skylake Msi models?

 

I do not know. @Phoenix is our guinea pig for MSI but he was not back with Skylake. Hey @ryzeki you still on team dragon?

Sent from my OnePlus 1 using a coconut

 

Don't expect @Phoenix will tweak his ram. A very pain for him if he needs to dismantle the whole machine if he run into ram problems. A nice laptop design? Dismantle the whole machine if you buy new ram sticks or want tweak it. Maybe other with Kaby and MSI could try.

 

I didn't expect RAM to be tweaked. I was only asking if Ryzeki (who to my knowledge should be on Skylake MSI) could check what the RAM options are.

When @Donald@HIDevolution was working with Phoenix's machine he told them that the machine would only default to 2400MHz or 2666MHz, so we knew from the start that the Kaby Lake systems could only handle that limit. Because Donald is a bro and doesn't sell things willy nilly that won't work in a system. *tear in eye*

But we don't know about Skylake.

 

I've just ordered these:

Kingston Technology HyperX Impact 32GB Kit (2x16GB) 2400MHz DDR4 CL14 260-Pin SODIMM Laptop HX424S14IBK2/32

I'll take the CL 14 @ 2400 over the CL 18 @ 2667...

Thanks guys for the insight.

Oh I actually own a single 16GB stick of this, I could have done some benchmarking for you if you needed to compare stuff before purchasing. I have no complaints about it, I thought the lower timings would be much better too

 

It'd be great if you could run some tests still. Really appreciate it.
