Help? BSOD/Crashes 32GB RAM (4x8GB)

[Sparx]

Morning guys,

Hope any of you memory wizards can help me on this... My mobo is the ASUS Prime X570 Pro and RAM I'm now using is Corsair's CMW16GX4M2Z3600C18 (2 sets of this, so 32GB - 4x8GB)

I had a problem earlier this year with my PC having BSODs consistently, apps and games just crashing and closing - which got worse, it was alleviated by removing a stick of RAM so I had a single 8GB. At first I actually thought it was my motherboard going ka-put on the memory controller or something? I asked ASUS and after 2 weeks they agreed to RMA, but part way through I thought maybe it's the RAM?

So I contacted Corsair who arranged an advanced RMA quickly. This didn't resolve the issue. But not wanting to wait for ASUS horrid slow RMA service and be without a PC, I bought the same Corsair style RAM but the 'AMD Optimized' edition (this one) and it seemed to have resolved my memory issues! So I left it...

Now I've just bought another of the same AMD optimised kit, so running 32GB (4x8GB) and I noticed Discord started crashing/reloading itself (RAM dumping it?), Chrome would randomly crash some tabs with "Status_Access_Violation" errors so now and I've had a few Windows BSODs - so I'm thinking here we go... Mobo issue again?

To cut it short, I've downclocked the RAM to run 3200MHz and it appears stable the last few days over the weekend. But why should I only let it run at 3200MHz?! It's rated for 3600MHz...

Is my mobo potentially faulty, or is it I need to tweak my BIOS better? I'm not that great with manual OCs, memory timings etc so would appreciate any help or advice as to what I could do. Some quick Google-fu suggests increasing DRAM voltage, manually input timings, changing command rate to 2T and all sorts. Not sure what the optimum thing to try would be?

Appreciate any help

Thanks

The kit I replaced earlier this year in CPU-Z shows it's Micron E-die. But the new kit I received at the weekend is Nanya A-die like you @uscool

So could be worth trying the newer Nanya kit in A2/B2 and the earlier Micron kit in A1/B1 slots then I guess, and try enable DOCP @ 3600MHz?

I'll also try bumping the DRAM voltage up @MrPils too if that doesn't work - and will certainly try bench on HCI MemTest @chrcoluk tonight after work

I just put the newer ram in A1 and A2 slots and the older in B1 and B2 not A2 and B2

My ASUS board states A2/B2 should be used as the first 'primary' slots to use, then A1/B1 to use as secondary. As the RAM slots go in order of B1, B2, A1, A2 (left to right).

So I'll give that a go, as it's the only other combination I can swap too lol. Currently my earlier Micron kit is in the main A2/B2 slots, with the new Nanya kit in secondary slots A1/B1.

Just as an update folks, I swapped the kits round as mentioned above - reset BIOS to defaults - enabled DOCP @ 3600MHz - and I've not had any issues since... *touch wood*

Spent a few hours playing Valhalla last night, browsing forums/Youtube the usual, and been working from my PC all day today and no issues at all. Neither Discord or Chrome crashed... so it really may have been THAT simple to just swap the kits round! Who'd have thought...

Well I'm pleased as I won't need to RMA my board now hopefully! Thanks for your help guys
