Aurora R10, memory upgrade

@Jkerns0824 

Please let us if the fabric is automatically set to 1,800Mhz.  Also, can you please remind me what memory you are using to achieve 3600?  I have been holding to upgrade to 64GB @at least 34000 and 3600 would be ideal.

After the Bios update to 2.1.3, I CANNOT USE THE MUSHKIN memory... not in any manual config, or OC1 as it was using before the bios update.  The machine won't post and gets stuck for a while until it kicks down to like 1066 instead of 1700/1733.  Anyway... wanted to let you know NOT to get that with the new bios.

However, with the new bios, my older Corsair 3600 ram DOES work.  OC1 works with slightly incorrect timings, but close enough.  And then I can manually set the timings to rated speed.  This is the specific kit I bought way back, and doesn't seem available right now, but I'm guessing similar Corsair 3600 mem would probably work ok with the new bios.

My machine runs around 122.xx mh/s with the dell 3090 card (modified and extra heatsyncs, and non-default card settings).  This is about what it was doing with the slower 3200 default dell ram, so not much different, but the actually memory tests come out much better.

AND, I verified in AMD's Ryzen Master program that Coupled mode is ON, and both the Mem Clock and Fabric clock are running at 1800mhz.  

For the heck of it, I kicked the manual speed down to 1733 instead of 1800, and other than the MemMark test being 50 to 75 lower, my hashing was the same, and machine performance felt the same.  I do think this BIOS really lets us use 3600 mem, but if you already got some decent 3466 mem, I don't think I'd bother spending money on the upgrade.  Too bad my mushkin ram doesn't work now... guess I'll have to mess with a return, dang it!

Corsair 3600 configsHad to use manual in BIOS to get this, otherwise it was something like 18-19-19-54Passmark's MemoryMark score

I also have confirmed via Ryzen Master that my Memory clock is 1800mhz and my Fabric clock is also 1800mhz. Coupled mode is also On.

  I have Corsair Vengeance lpx 3600   not the flashiest but gets the job done.  

i may mess with ryzen master to tighten up the clocks but for the time being I'm just glad that the ram and smart access memory are working. 

Ok, this is dumb, and I swear I read all the way through this thread... Today, after my computer has been off and the machine WILL NOT POST with the corsair 3600 ram in there.  I have no idea what the problem is with this dumb motherboard.  If I put my 3200 ram in, then switch it to AUTO, then swap back in the Corsair 3600, then change the timings to full 3600 timings in the bios, the Corsair will work.  But I don't want to swap ram sticks every single time I turn off the machine!  What the heck?  Does this motherboard just hate faster ram, or does it not like 1.35v instead of the 1.2/1.25 volts of the hyperx mem?  Thoughts?

Multiple other users have reported odd issues with memory support and the latest bios.

For some reason they seem to have broken memory support when trying to add resizable BAR support.

I would suggest to put in the original ram the system came with for now. It looks to me like the Resizable BAR introduction was specific to the OEM system memory configurations and messes up aftermarket configurations.

Hopefully another fix will fix that issue. You could also try disabling resizable BAR in your new bios and see if that solves the issue. Maybe they introduced another issue that we are currently not aware off.

@Vanadiel  I have the original memory back in, and all seems to boot and be stable for the moment.  I guess I'll keep working on it to see what might be best, and I'll be careful with future updates, also.  I guess the new bios settings along with the ReBAR isn't all setup and working yet.  Maybe I'll try the memory @Jkerns0824 is using as my next attempt.  Thanks everyone for the information and help!    I'll post with more attempts as I go.  I'll do more extensive testing before the next posts, however...  

My R10 is still being prepared, so hasn't arrived yet.

Have purchased the https://www.amazon.com/HyperX-Black-3466MHz-HX434C17FB4K2-32/dp/B089QSG4S9/ so hopefully still compatible by the time it arrives, and future BIOS upgrades haven't become incompatible.

@Jaxsonnz Do you know, is the HyperX 3466 single rank or dual rank?  Can't seem to find that info online.

I did try the 3200 Crucial Ballistics other's said work.  There is an oddity with my setup:

I have the R10 with the 5900 (non X) processor.  It seems there is a voltage limit for this CPU, so if I use faster ram (which doesn't always boot right anyway), then if I'm running heavy processing across all cores, the speed is slower.  

3200 ram, all cores run around 3200 to 3300.
3466 ram, all cores run around 3000 +/- just a bit.
3600 ram, all cores run just under 3000 at all times.  

In my reading I have found there is a max voltage that can be applied, so when using faster ram, the maxed out cpu is therefore slower.  I haven't tested with single threaded, and I don't know if this applies to the 5000X versions that run at 105watts instead of my 65W processor.  

Side note: I got the 5900 non X because I wanted lower power usage for crypto mining, but I do use it for some gaming also.  Heat is a problem in my box, and I have replaced the stock fans and added 4 more fans to assist with cooling.  So I guess it's probably better that I didn't get a 105W processor, but it just means full core usage runs slower than I had hoped.  Oh well.

Core speed will drop with core temperature.

Therefore, if faster ram is increasing CPU performance, the CPU cores in turn will produce more heat and the core frequency might become lower.

Did you have liquid cooling? Under normal circumstances with a 65 Watt TDP on the processor it should be able to keep the temperatures stable when using faster ram.

@Vanadiel 

I did buy the alienware liquid cooler, and my temps stay at 65 or just under, regardless of whatever ram I am running.  I suspect that when mining, my video card is the thing heating up the box quite a bit more (hence the extra fans), but even when first starting up the heavy CPU monero mining, the core speeds are truly dependent on the ram speed as the temp isn't up yet. For me...  Faster ram = all cores slower.  Again, I haven't paid attention to CPU speed when just a few cores are in use.   

@Jkerns0824 

I'm glad you got it all stable and working at 3600!!!  I kinda wish I hadn't gotten this 5900, and gone with one of the X processors instead.  Well, it's done now.  If I do more playing around with configs and memory, I'll post back again.  And I hope future BIOS updates make things better for all, and not break anything!    

I personally went with the 5600x, 6800xt combo and have zero regrets. Not sure how many gamers are here but for context I play a lot of Call of Duty Warzone.  1440p ultra settings 

Verdansk- 174fps. Average 

Rebirth island-   189fps Average

both maps regularly hit over 200

As far as the cpu performance while gaming and broadcasting I regularly hit speeds as high as 4.6. Ram running at 3600mhz, 1800 fabric clock. 1800 memory clock. No issues with the cpu speed.

Cooling - I added a Corsair H60 liquid cooler.  I also have 2 Corsair ml 120 pro fans coming. I will be replacing the stock front intake fan and adding an additional intake fan in the hdd expansion bay. 

Hey I am really confuse about all of this. I am new in all this PC gaming word and i just wanted a plug and play PC.   I bought the R10 Razyn 5900 (no X) with a 64GB Dual Channel DDR4 XMP at 3400MHz; and RTX 3080 10Gb. So for what can i see if i dont have the "X" in the CPU the computer is not going to perform concordantly with the 3400MHZ? 

@Yancio If you ordered the ram directly from Dell, then it should all work great, particularly for gaming. 

My issue with my 5900 non X is when I'm trying to maximize both RAM speed and All Cores running speed.  During gaming, you won't be using all your processor cores at max speed, only a few.  So the cores that are running, should be hitting the faster and/or fastest clocks available.

And again, if you ordered it all from Dell, they have the parts that work well together.  The rest of us are just trying to get cheaper ram as fast as we can, and that's our problem. 

It will work well, I have an R10 myself and never had an issues with it.

Just make sure to use the Alienware update program to install the latest updates when you get the machine.
