Sudden issues after upgrading RAM from 32 to 64GB??

[TangentalV]

Hey there everyone!

 

So I've been encountering a TON of crashes/errors that I was not having before after upgrading my RAM, from two sticks of Corsair Vengeance Pro DDR4 3600, to 4X 16GB sticks. 

 

I purchased them from two different vendors (Amazon and Newegg) and it appears that the dies on my sticks came from Samsung, and Sk Hynix, with my original sticks being the Samsung dies. I'm not exactly sure which set came from where, but I suspect the Samsung BDIE sticks came from Newegg.

 

I haven't done anything with timings/voltage, as I'm not super knowledgeable with that (but would be willing to give it a shot!) I do however, know my way around the BIOS fairly well. My timings seem to be just slightly different across the sticks, but not by much.

 

Could anyone shed some wisdom on my foolish self -- is it problematic to be running multiple different manufactures, of the same 'type' of RAM...? Also, even with XMP enabled, I'm showing TERRIBLE RAM speeds, of about 1799Mhz, on sticks rated for 3600. I'm running a Ryzen 3700x, on a MSI B450 Tomahawk Max MB.

 

Bit of RAM info below, for anyone brave enough to peruse it:

Help?

Mixing the Samsung and HK Hynix memory dies are part of the problem as memory controllers like to have them all from the same batch/family from a memory manufacturer, i.e. all from SK Hynix or all from Samsung. That's why it's recommended to buy your kits at once to ensure you're getting two RAM kits that were shipped out together and are from similar batches. 

 

Did you make sure to clear CMOS after adding the 2nd kit? Anytime you touch the RAM (adding or removing), you'll need to clear CMOS as you have to do memory training again.

One thing from your output is that you're running one pair in slots 1/2 and the other in slots 3/4.  This means that when interleaving in dual channel mode, you're hitting two different spec memory modules.

 

One pair should be in 1/3, the other in 2/4.  And, if it doesn't help, try swapping which pair is where.  It's perfectly fine to mix and match memory modules, so long as you keep pairs across the channel from each other at the same memory addresses, and your slower memory (in this case, the Samsung is the slower) as the electrically first module.

Hey there!

 

So I'm not sure why on earth that particular RAM info output displays like that--but for whatever reason, it's actually incorrect! 

 

In a typical 4 slot array, I currently have my original 2 sticks inserted in slots 2, and 4.

 

The two 'new' sticks were inserted in slots 1 and 3.

 

I actually just popped out the 2 'new' Samsung BDie sticks, cleared CMOS--and my system is back up and running at the advertised 3600 mhz speeds. That's actually surprising, because the general consensus online seems to be that the Samsung BDies are the 'lucky lottery' desirable ones, as they seem to have the most overclocking overhead. (granted, I'm not OC'ing beyond just simply enabling XMP).

 

Dunno. I'm guessing my best bet at this point would be to return the 2nd set of sticks, and either try and get another set that matches the original manufacture of my OG sticks, or just settle with 32GB. (I'm leaning towards the latter)
