BSOD's, freezes and crashes with two RAM sticks

[creepyNuts]

So, I've bought everything new: Ryzen 5 2600, HyperX Predator RGB 8GB RAM memory and B450 Tomahawk Max mobo.

All fine, I played for like 5-6 days 0 issues. Then when I've got my second 8GB stick of the same RAM ofcourse + new SSD, I have done a system reboot and put another 8GB and SSD in..

Here is the problem, when I have 2x8GB ram, PC freezes after 5-20minutes of doint anything or playing a game. I tried changing all different stuff in BIOS but 0 effect, it freezes and I can only hard reset the PC.

Now when i got 1 RAM stick out, it works perfectly fine...

Tho its the exact same RAM as the other one, they are set as: A (B) C (D) in the slots

Anyone possibly know whats the issue with having two ram sticks at once?

Perhaps you need to clear your CMOS to force your motherboard to re-run RAM training.

Means either

1) one of your sticks is bad
2) one of your slots is bad

[The HopelessGamer™]

Test your ram using a bootable program called memtest86. One of your new sticks might be faulty.

To mount the program to a usb stick, use a program called Rufus.

Using the tool is simple. Plug the usb in, turn on the machine, spam the boot loader button. The button will be listed in your motherboards manual. Otherwise it is one of the F keys. F10 usually i believe. Once memtest is up, follow the prompts to run a test.

I recommend checking the air flow. I had a freeze issue myself and found it it was because dust particles appeared in the open RAM slots.
I used tape to seal them, turned out it helped, but was a bad idea. e.e;
basically, I recommend not using tape, but keep air from flowing into or over the open slots so that dust cannot (after nicely getting a charge) spark stuff in your RAM slot and causing a global freeze.

I suppose if you have the air flow set up correctly, the fans would suck up dust before it ever reaches the slot, but still. If you can't. I recommend sealing it.

That it works fine with one can have to do with the location of that one RAM stick. If it is against of below the fan, then chances that the other three slots are skipped are greater due to no wall in the way where a particle can bump into.

If you see something in the ram slot, blow it out before placing your RAM in there.
You can use household tape to seal the other two slots and test if it helps any.

If the ram is more speed than default "max", reduce it a bit.

It is best to buy ram kits right away, or this can happen. If both run fine each on its own, they are technically not broken. But you could ask the seller what to do though.

Try both sticks separately in the main slot first, if you crash with one then you already know it's a faulty module.

Could be a timing issue as well so make sure to clear cmos/bios properly(check your manual) to retrain timings and get typhoon burner to see if it shows the actual ICs cause if you bought them separately it may still be different hardware inside them like samsung, nanya, hynix, micron. Generally with Kingston if I see far apart manufacture dates then I just assume it is different.
Might be worth relaxing some of the memory timing settings in bios to see if that helps.
Could also be things like a faulty slot, cpu issue or maybe even gone faulty from esd.

Is this because kits are guaranteed to have RAM from the same batch and thus more likely to be matched in characteristics?

I think they were tested together

Yeah, idk about that. I think its just a marketing trick. I noticed sometimes when I order a dual kit, I get two singles xD

I don't think it matters much if they were a kit or not, so long they're the same (from the same stock) you shouldn't get problems. I think you can go cross brand as well, but it's not garanteed stable since they may use different measurement methods. A simple tick on the overclock settings fixes that though. (most of the time my sticks are overclockable, so I don't even need to.)
It might get tricky when one RAM stick requires more voltage than the other. (then yeah you'll lose speed, but downclocking doesn't cause bsods or hangs even without it being set properly)

Never really tried different RAMs to be honest, I probably should test that or find someone that did test that. I mean different in minor specs, like cas latency or brand. hm... e.e;

Modern chipsets and onboard programming often solves a lot of issues automatically. It can even detect flaws. xd

Edit: interesting

In his case I would recommend downclocking the frequency on the dram to match the slowest stick, so that it all lasts the longest.

Surely they must have chips from the same binning so as not to cause timing issues when used dual channel?

But they still could have been tested together.

Kits are not more expensive, so i dont know why that should be marketing

Companies want to sell their own products as much as possible.
If you use more copies of their products they gain fame and sell more.
You're more likely to buy from them again yourself as well.
and they want to prevent people from mixing things or try out others to keep selling you their stuff.

For a shop it works well as well since its easier to sell with a discount on a dualpack then a single one (due to the myth that one must have exactly the same product for it to work) (although garanteed yes true), so kits basically sell better in the end than singles.

Most motherboards have two slots so most kits are dualkits.

Basically: tl;dr its a psychological thing mainly I think

Edit:
forgot to comment about them being tested together.
They test a few samples and batch them all in boxes in the factory.
e.e; it gets worse when you realize at some point a lot of the different branded stuff comes from the same factory and is a reskin of it.
Anyway uh... yes and no?
They test it in the factory. After that the one that orders basically decides what the kit is.
and they don't get tested after this, as in... the factory test is the only time the product is 'used' before the first end user.

The guy in this video had an issue similar to OPs current problem. That's why I posted the link.

That's actually wrong because ram companies like corsair, kingston, crucial etc will not specify exactly what ICs/chips are in the modules when buying and they may move from samsung to hynix or micron as an example when production changes over time(generally in favor of costs).

Even if you buy at the same date, how do you know one isn't older stock etc.. you can't until you check in a program like typhoon burner or take off the heatspreaders and have a look.

I just want to clarify it generally isn't an issue to use completely different modules as motherboards are designed to take this into account and compensate for it by running slightly relaxed/slower timings etc but when swapping over ram with completely different ICs it can cause some havoc and generally show up as a boot error.
If I had to guess I'd say one of the modules has an intermittent issue which may not even show in memtest as that's not good enough to check everything.

When you buy any kit make sure to double check the part number on the manufacturer page as this should not happen with any reputable retailer.

sorry for not responding for few hours, it was late morning.. Now i am testing the second stick of the RAM by itself and it seems that it is pretty fine, no faulty issues within 1 hour so far

[creepyNuts]

Update: PC just had BSOD with KERNEL_DATA_INPAGE_ERROR which is also known for a bad sector, virus, a hard disk error or a failing RAM memory... So theres that, I am getting a new stick after all
