Some time ago I had blue screen problems, as everything was new, I sent my ram memory for warranty, they sent me the same memory saying that it had been "repaired", after a few days of use I decided to test it on memtest86 that it had 3 errors, I did it 2 times in a row to confirm, it didn't give a blue screen yet, but it has the errors from before as Google Chrome stops working with the status_breakpoint error... could the error be memory? I already bought another motherboard and nothing worked, the only thing I haven't sent yet to guarantee was the CPU.

I already formatted the computer.
I've already run cinebench on the processor, temperatures 60-65 degrees.
I already installed on another ssd windows.
I disabled DOCP
Bios is already in the latest version.

memtest86 only gives an error when it has both memories in Dual Channel, if I test 1 at a time it doesn't give an error.

I don't know whether to send the memory for warranty again, or send the CPU, or send both...



And sorry for the English, I don't speak very well.

At least that indicates each RAM sticks are functional. Assuming RAM sticks are equal and from same batch (bought as a set) and that they are listed in Asus Memory QVL (Qualified Vendors Lists).

So next logical move would be put both sticks together but in single channel mode and redo memtest.

If the test passes, with both in single channel, could the problem be the CPU? because i just changed the motherboard, i don't think it is the problem.


I'll test it tonight and as soon as I'm done I'll let you know here, thanks!

Too early to call. Do the test, we will see what results tell us. Then we might do more testing until we have as clear picture of the problem as possible. But yes, memory problems can be caused by CPU.

One more thing, which slots should I use? 1/3 1/2 or 3/4 for the single channel test or whatever?

Where these sticks of ram bought as a kit of 2 sticks or you bought 2 separate sticks?

That might explain the ram errors with memtest.

but they are the same model, frequency latency, all the same.
I researched before buying and saw that there would be no problem, as long as they are the same model, same latency, frequency etc...

If you bought 2 separate sticks there could be just enough difference between them to cause problems.

Here just an example notice it's one part number but 2 sticks of ram in a pkg.

If this is the problem then I'm very unlucky, my old pc also bought separately and never had any problems... :/



I'm going to run memtest86 with both sticks in single channel and tomorrow I'll send the result here.

Hello guys, I did 2 tests this morning, I did it again in dual channel and in single channel, in dual channel it gave 1 error, and in single channel it didn't, should I trigger the warranty?

So that would imply the sticks themselves are fine. For a added measure, if you tested with DOCP off, redo the single channel test with DOCP enabled to make sure they are 100% good as a pair.
Now, the next thing to consider is motherboard (I know, new one, but even new one can be faulty). One of the slots may the source of the errors. Test the remaining two slots (for example if you used slots 1-2 now then you need to test 3 and 4) with just one stick (since seems both sticks are fine it does not matter which).

I've already done that, it doesn't matter which slot I put it in, if it's in single channel it doesn't give an error.
I think the problem is not in the mb, because I already had blue screen memory problems with the other old motherboard... I changed the motherboard thinking the old one was the problem and it didn't work.

So you tested all four slots and each alone (or in single channel pair) passes test, correct?

Sure, but we could not exclude beforehand the rare situation where new motherboard is faulty in same way as old one.

To sum it up: Seems like sticks are fine. Motherboard slots are fine. So the problem is either with compatibility between the sticks or CPU. The former seems a bit unlikely to me as in such case the memory behavior should be same no matter if put in dual or single channel. Although I cannot rule this out with 100% certainty I'd consider the fault be on CPU side.
Now, this does not necessarily mean CPU is bad. It could be slightly bent one of CPU pins, or even something such trivial as unevenly tightened CPU cooler causing this sort of trouble. While it may seem unlikely because you already changed motherboard so you have to move cooler too but it is still possible.

I went to turn off the computer now and it gave a blue screen, the same as before changing the motherboard, memory management error.


I forgot to mention, I used an r5 1600af before, with these memories, and one day I got this same error, memory management, I don't know if it's a coincidence or the 2 CPUs were having a problem....



i'll contact the store and try to swap my sticks... i'll see if i can get a kit, if after swap i still have errors, i think it's probably the cpu.
