17 R5, 64GB of RAM?

Samsung recently released the industry's first 32GiB SO-DIMMs, about which you can read here. The new SO-DIMMs are now available for purchase in 64GiB kits. I was wondering if the Alienware 17 R5 supports the SO-DIMMs and 64GiB of RAM. I know the CPU supports the RAM. Does Dell need to release a BIOS update or does the laptop already support 64GiB of RAM?

 

Thanks,

Once I've bought and tested the Compuram.biz 32GiB SO-DIMMs, I'll get back to you

Hi computer enthusiasts!!

I was wondering if there have been any updates on this yet?

We need modules with 4G chip configs (max 4 memory chips per side of the module) for the 64gb to work in Dual Channel, then the Crucial 32GB 2666 ones are what you need. If the picture on newegg is correct, then they are running the correct 4 chips per side or 1R config or single rank. It appears the BIOS can ONLY address a total of 16 memory chips, meaning if we want to run in dual channel mode (2 memory modules), then there can be a max of 4 memory chips on each side of each memory module. If the pictures are correct on newegg, Samsung modules are using the 2G chips, resulting in 8 chips per side and will not be addressable by the hardware in the 17 R5 when two memory modules are installed, as that is a total of 32 memory chips. I have only seen this level of specific ram compatibility in server applications. https://www.newegg.com/crucial-32gb-260-pin-ddr4-so-dimm/p/0RM-0006-00DN1

I also may be completely wrong

https://www.anandtech.com/show/14341/samsung-samples-32-gb-ddr4-memory-chips Actually, this article holds the key. The 2Gx8 organization is seen as "two memory devices" and is packaged with 16 chips, where-as the 1Gx16 organization is seen as "a single memory device" and is packaged with 8 chips. So, if you install two 2Gx8 organization modules into our AW17s, then it will "see" 4 memory devices, but software/bios may not be configured to recognize four devices, since there is only 2 slots? Also interesting is the memory you posted from that third party package shows a 4Gx8 configuration, so I wonder what the difference is?

You make some good points, but I don't see how even the Samsung 32GiB SO-DIMMs would be incompatible with the Alienware 17 R5 8950HK model. According to Compuram.biz, the modules they sell, at least, are compatible. The data sheet mentions some type of "4Gx64" configuration for the chips on the modules, but those numbers don't make much sense. I know that 64GiB of RAM *is* compatibile, and that something is just wrong with the UEFI BIOS. First, when I had bought the 64GiB Samsung SO-DIMM kit, I got my laptop to boot into the UEFI BIOS, which is a tiny OS unto itself, and, it saw all 64GiB of RAM. I then ran about 1.3 passes of PassMark's MemTest86 memory tester on the RAM in my laptop. I should mention that I booted off a USB flash drive into MemTest86 via the UEFI BIOS. MemTest86 read and wrote to all valid and accessible locations in the memory without reporting any errors, and at 2666MHz with the SPD timings. Here is a picture :  It still seems to me that there is either a purposeful BIOS lockout by Dell or just a bug in the UEFI BIOS. I was able to get Windows 10 to "boot" but it immediately bluescreened with some type of "DPC_WATCHDOG_VIOLATION" error.

Well I can confirm that CompuRAM sells good modules. I bought for my G5 5587 2X32GB(64GB) of RAM and it works great. I have run test with their Raminator and got individual offer for 64GB. Great company.

I think the main problem here is the Alienware 17 R5 BIOS. The BIOS version in your DELL G5 is probably different from that of the Alienware 17 R5.

Hi

 

I have Alienware 17 R5 i7-8750H... The default RAM was 16GB which I hoped would be single stick and I thought of purchasing another 16GB and upgrade to 32GB... But it came with 2 x 8GB :-(... Nevertheless I am looking to upgrade so I have decided to upgrade to 32GB... But I faced a peculiar issue, in dell website they have mentioned that Alienware 17 R5 models is not compatible with 2666MHz RAM modules (link below)... 

As per this article my laptop is not compatible with 2666MHz, But when I bought on the website it was clearly mentioned my laptop can handle upto 2666MHz RAM, Already DELL has soft locked 32GB instead of 64GB and this too... 

Experts please clarify this issue for me please... I am in dire need of upgrade

Dear Dell ,

Please remove the lock!... It is a travesty for a 400$ Intel NUC to accept 64GB and my almost 3K$ alienware 17R5 which is supposedly the 'flagship' alienware laptop (at the time) not to support the RAM when the BIOS can -definately- see the RAM just FINE!!!!!

That is the EXACT nuc i am running the 64GB Samsungs with and it's running just fine..

This is an absurdity that we have to deal with this .. I had to switch to the damn  NUC as my main developement machine which aggrevates me to the max that I have a nearly 3K$(CAD) top of the line alienware sitting on my desk that i cannot use for what i bought the laptop for..

The hardware is definately capable... The BIOS can see and boots with the RAM fine.. This is definately something artificial snuck in there... If this was something "incompatible" or if the BIOS could not see / view all the RAM it would not be able to boot with it to begin with...

I doubt Compuram.biz ram wll work any differently... If the BIOS could not see the RAM maybe it's a RAM issue... It's definately NOT !

I am not "pirating" software. I just want to know how **an owner of a 17 R5** can mod **their legally owned machine** , in terms of the BIOS, so that one can get 64GB RAM support, nothing more, nothing less.

I payed over $4.5K for my top-of-the-line Dell Alienware 17 R5, including a 3 year warranty, and Dell has the gall to just pull my post because they believe it to prove my point that their software lockout of 64GB of RAM is possibly quasi-legal!?

In the mean-time, I'll be upgrading my NUC to 64GiB of RAM for Xilinx's Vivado Design Suite's needs, but my CAD ( Alibre ) software only runs on my 17 R5 in Windows 10

I am not sure Dell really has a say if you want to mod your own bios, throw the laptop out the window, chop it up into firewood(though i would not reccomend it!) or smash it against the wall , or 'expiremen't on it with a sledgehammer
