Aurora R10, memory upgrade

@MobileGuru I would like to know the answer to the same questions also. I bought the 16GB DDR4-2666 RAM when I ordered the computer but I want to upgrade to 32GB of DDR4-3600 RAM. I read that DDR 3600 is the best performance "sweet spot" for AMD Ryzen processors. I'm wondering if I bought 3600 mhz ram and change the XMP profile if it would work.

I’m so glad I started this thread, very useful info.  

For those who have ordered third party RAM, what’s your experience so far? I will order at some point but I’m still thinking about which one would be the best purchase for my R10 with 3700x. I was looking at a few options and wondering if the consensus is that they would all run at 2933... and if some believe that they will overclock any higher, be stable and not cause startup issues... Please keep sharing your experience! At some point I might go to 64GB but for now 32GB should work. It should  still be an upgrade vs the 16GB 2666 my system came with when I get into my video editing projects.

1) 3200 C16

2) 3600 C16 (+CAD $20)

3) 3200 C14  (+CAD $120)

Thanks for that information, Can you provide me a link as to where to purchase the official Dell memory chips on the Dell site? I have not been able to locate them using the model numbers provided.

Are they even available for purchase from Dell or are they BTO only offerings?

Try contacting Dell via chat and giving them your service tag, they will give you a price quote for the correct RAM, if in stock. 

Thanks, I tried that but they didn’t seem to know anything about it

So I got the memory you indicated in  your earlier post, 2 matched sticks and an additional single stick. Put them all in and...the machine no longer booted.

SO then I dropped back to the original Dell stick and it came up fine. At this point, I realized that XMP wasn't turned on so I enabled it to "Auto". Added the extra stick and it booted up to Windows, showed the additional RAM, seemed to run great until... I ran the Alienware Command Center to look at the memory settings. 

So then I removed all the memory, added the 2 new matched sticks and booted it. Everything came up and ran fine. Memory is set at 2934Mhz instead of 3200 as before with the single Dell stick.

The voltage is also 1.35 volts instead of 1.25.

I ran the system tests a couple of times and had no issues. The system had 32Gigs and everything seems to be fine.

Now my son told me that XMP would automatically handle 1.25/1.35 voltage settings and would drop the sticks down to 1.25 if necessary. This doesn't seem to be the case, so I assume there is some place to set that. 

It would be nice to be able to have all 4 sticks (1 Dell original 16 GB) and 3 HyperX sticks of the type you had recommended get me up to the 64Gb limit.

Any thoughts on this situation?

Sorry I said my 64 GB memory was working fine at 3200 Mhz. It turned out only when the machine boots up for the first time after changing memory would the frequency be 2933 Mhz. After I actually enter the system/reboot, it would be 2400 Mzh! I suggest you all check again to see if you actually have 2933 or 2400...

I had to enable memory OC for it to actually reach 2933 Mhz. I have not found a way to make it 3200 Mhz neither. Nevertheless, OC it to 2933 Mhz seems pretty stable so far, perhaps because 3200 Mhz memory chips are meant to be able to handle even more voltage or whatever. 

Anyway, this memory thing remains a mystery... 

So I have had horrible experience with Dell support. They are unresponsive and tend to kick everything to "sales support" who contacts me and tries to sell me something without asking what the actual issues are even when I state them in excruciating detail in my emails to them.

However, thanks to the community postings in this forum, I was able to upgrade the memory in my A10 to 64 Gigs.

I ended up using the automatic configuration mode in the XMP part of the Advanced Bios settings. The Dell memory chip is a lower voltage chip, but it does have a 3200Mhz memory profile. For some reason, the Dell Bios doesn't select that, it sets everything to 2940Mhz and is able to run without issue. I ran Dell diagnostics as well as the Microsoft memory test and it reported no issues. I've also run numerous games and applications on the machine without problems. 

The memory I got was from Amazon as posted by a previous member. It is: HyperX Fury 32GB 3200MHz DDR4 CL16 DIMM (Kit of 2)  Black XMP Desktop Memory HX432C16FB3K2/32

I also got this one: HyperX Fury 16GB 3200MHz DDR4 CL16 DIMM  Black XMP Desktop Memory Single Stick HX432C16FB3/16

My system is running at 2934 Mhz at 1.35v with the following numbers:
tCL 16, tRCD 17, tRP 17, tRAS 36.

These were all selected by the autoconfig in the Bios once I turned on the XMP auto option in the Advanced performance settings. Note that it did take the system a couple of reboots to work, but once it comes up, everything seemed to be fine. I tried some of the other XMP profiles but they didn't work. It is probably possible to get the memory up to 3200Mhz with manual settings, but I've decided that 2934Mhz is probably fine with dual channel RAM for now.

I did double check all that. I used CPUZ as well as the Alienware tools to determine the current memory speed. I also had to enable OC and XMP to get it to go up to 2933Mhz as well. 

Looking at the XMP profiles for each memory chip, there is a 3200Mhz profile for both the Dell-branded XMP HyperX memory as well as the standard HyperX memory. The difference is in the voltage. Memory queries show that my memory is running at 1.34v now, but it doesn't show voltage for each stick. I'm not sure that the motherboard adjusts voltage different for each stick either. That's not something I've been able to learn from any sources yet. A question to ask an actual, mythical, Dell representative...

I to upgraded from the 2666 to the 3200 i purchase my ram on Amazon. If you put on OC2 it runs at 3200mhz. What i found out is when you shutdown and try to reboot it will not reboot. I then have to go in and put on auto instead on OC2. One thing i did noticed in the custom settings it didn't give option higher than 3000 mhz. Im thinking the bios is set that way and you cant achieve a stable 3200mhz. Just my 2 cents!

I think the problem might be in the memory voltage. What is the voltage of the RAM chips that came with your Machine?

I'm not certain if it was just luck or what but I had zero issues upgrading my machine today.  After reading this thread, I was concerned that I'd have issues.

Today I installed (4) 16GB Corsair 3200 sticks, turned on the machine, waited for about 3 minutes before BIOS kicked in, and shazam, all good.

The BIOS automatically picked up all of the RAM, recognized the 3200 speed, enabled XMP, and set the voltage to 1.35.  I literally did nothing but insert the sticks and turn the machine on.

That’s awesome! Thanks for sharing! Your the first person to show success and using Corsair sticks. 

would you mind checking with CPU-Z (or anything similar) and sharing the screenshots? I’m asking because a few weeks ago someone else told be they had success but when they checked their system had reverted to a lower speed.  I really hope you solved my dilemma regarding which sticks to purchase!

cheers!

Virtually identical net speeds on those two options:

14 CL at 3200 = 8.75 nanoseconds total latency

16 CL at 3600 = 8.89 nanoseconds total latency

Generally CL matters more than speed, for instance the 3200 stick at 16 produces a 10.0 total latency.

Wow that's good to hear! I did get HyperX since that's like the OME brand. I also got 2 32 GB sticks so I am not sure if that has made any difference (put in white/primary slots).

Thank you so much! I am kinda busy to try it these days but I look forward to others' good news too.
