BSOD when enabling RAM XMP

[Brilew]

Hey!

I just bought 2 extra 8gb sticks for my PC to finally have 32gb's of RAM as 16gb's clearly wasn't being enough for me.

I have a Ryzen 3700x and heavily count on a decently high MHZ to get the most out of my Ryzen.

I had 2x8GB Corsair Vengeance adverti sticks with Hynix dies and used the XMP (3200MHz) profile with no problems. Right as I installed the new mem sticks (2x8GB Corsair Vengeance except it came Samsung B-Die) and played for a while, I experienced a MEMORY_MANAGMENT BSOD. I searched around but nothing solved the BSODS except disabling the XMP, leaving me with the standard around 2660MHz on my RAM sticks.

Do you guys have any hints on whatever is causing this problem? Thanks, any help is appreciated.

My current motherboard is a X570 Aorus Elite.

Do a "Clear CMOS" and then retry the XMP. Maybe retraining the memory will help (which it does when CMOS is cleared).

increase dram voltage to 1.4 and soc voltage to 1.1

I think you may have solved the mystery with this one. Mixing IC's is never really a good idea. They tend to have different tertiary values that they prefer and often conflict with one another. Often times, people don't recommend mixing brands of memory or speeds of memory, but the real issue stems from mixing the different memory IC's. 

 

You can try doing as @boggy77 suggested and throw more voltage at it in the hopes that it might become stable, but short of that, you'll have to manually dial in some timings that both IC's will agree with. If you have to go that route, be prepared for a lot of trial and error and a lot of stress testing. There won't be a simple "dial these timings in and it will work" kind of answer you can get, as it's going to be up to your IMC and DIMM's at that point.

I see, thanks! Its really unfortunate as I specifically went for the exact same model as I purchased previously, but it seems that the lottery got me on that one, different RAM dies. Well anyways, thanks for all the help, Ill def try to do the manual timings thing. Also, isn't it possible to have different timings for each memory channel?

Depends on the board, but yes, the IMC itself is capable of training timings on a per-channel basis. If your board supports this, you should see two different values next to each timing, one for each channel. If the board supported this, it should work in theory, but you might run into some odd performance quirks when interleaving between the channels. I have not tested this personally, so it's definitely worth an investigation.

 

As for ordering the same DIMM's, I've had this exact same issue myself many times. With Corsair specifically, they'll use identical part numbers but have different revisions. These revisions are often where they make changes to the dies themselves. This was definitely true when they were trading off back and forth between Hynix AFR and MFR.

 

Really wish there was a better system in-place to designate which dies are in which DIMM's, but I doubt we will see a change in the industry standard for advertising memory configurations to accommodate this practice.

Thanks, Ill def try to do that as well. Im quite of a layman as of messing with memory settings on the BIOS. Should I leave the XMP on, and then increase the voltage? Or copy the XMP timings manually and after that change the voltages?

leave the xmp on and change the voltages manually

unfortunately that didnt work. I tuned down to 3000MHz with the voltage you specified. I'll test it out and see what works. I'll also try to update the bios, if that is a matter to consider.

yes, a bios update will help, as they usually improve memory support with each update

Bios update + your voltage settings worked. Thanks a lot man!
