Question Some of my ram is bad. But which ones are bad?

[bmost4395]

Bought 2 ram kits (CORSAIR - VENGEANCE LPX Series 16GB (2PK 8GB) 3.0GHz DDR4)
So I can finally have 32 gigs and some good speed. Was hoping for luck with my ryzen system.
was trying to hit 3000mhz which i know is a pipe dream with a ryzen system.
was staying at pretty safe voltage. No farther than 1.35v
and kept getting a Kernal blue screen UHG
so decided to run at stock ddr4 2133mhz
AND STILL GOT KERNAL
sad day!
did diagnostic and sadly yes... Some bad ram. (How can I tell which stick is bad out of the 4 sticks I got?) I only have 4 slots by the way so no channel issues.
Do i have to go trial and error mixing the ram until it says no problems?
Or can i riddle out these results and somehow understand which slot has the troubled ram stick.

The most reliable method, in your situation, is to pair it down to a single DIMM and test, then switch DIMMs and re-test...

Okay so this is weird. Last night I tested all the ram switching around and all that jazz.. After testing all the ram 2 at a time... NO errors... But when all 4 are in... It says i have failing ram??? Is my ram broke or what?
This is so confusing

Alright I did another test with all 4 sticks... And no error this time???
Could there have been dust or something in one of the slots causing this?
Or should i suspect there is still problems here?

I'd like to go on pushing the ram to at the least 2600MHZ with its 3000MHZ on the box.
How should I go forward guys?

It could be a failing Dimm Instead of a bad stick of ram. I assume you were using the same 2 Dimms when you were testing the ram 2 at a time leaving the other 2 empty so it could be a problem with one of the other 2 Dimms. Has it been consistently booting without error since this post?

I have not had any problems yet and I've had an up time of around 3 or 4 hours.

The other day all 4 sticks would cause a Blue screen and now it seems to be stable

RAM is only guaranteed to work together if bought as a kit. Combining two different kits, even if the exact same model, may not work.

I can see that definitely.
But what are you saying? It seems to be working now and windows diagnostic says no errors with all 4 sticks

I'm just pointing out why you could have issues even if none of the sticks is actually faulty. If everything is working now I guess you're good, hopefully it's not some intermittent instability that comes back.
