arkantos91 Thanks for your help guys.

A little update: tried both sticks in my friend's computer. This guy has a B450 Asus board: the good stick worked as inteded, the bad stick didn't even make the computer post at startup!

Then I had the chance to try my ram in another friend's computer, this time a Gigabyte X470 board (like mine, even if not the same exact model) and the behavior was very similar to the one I have on my computer. The PC starts and gets to Windows with the faulty 8 GB stick but doing a memtest86 causes the pc to reboot.

The only thing that still does not convince me is the fact the sometimes it takes a little bit longer for the memtest to fail... sometimes it fails very quickly, other times it takes a minute or so. The answer I gave to myself it's that probably there is some "sector" of the ram that is damaged, and when that is accessed, the freeze occurs.

I have to go through the RMA process now and really don't know how much time it will take.... so in the meantime I bought some 4000 MHz Kingston (HX440C19PB3K2_16). I know they won't ever go to that speed but they're B-die so they should be a little better at least.

These are Kingston too, let's hope for the best-

Maracus Those running F41a, sometimes after changing memory clock or failed clocks and loading profiles the board sets SoC voltage to 1.2v even though its not on auto. Not very healthy.

One of the two ram sticks seems to be faulty then. To be sure, I think I will try my ram kit in another computer (thanks to a friend who also have a Ryzen+ CPU).

If the same stick will fail in another PC too, then we can conclude it's one of the ram stick that got somehow damaged.... do you agree?

Meanwhile I think I should already start looking for a new 16 or 32 GB kit of ram (depending on price difference)... only requirement would be not being high profile. And B-Die this time would be nice too. Any suggestion for a kit compatible with our motherboard? I've had enough of the hassle I had with this hynx chip which have never run over 2933 MHz
I completely agree, I'm happy I could help you solve this problem. Just go with 3600MT/s CL 14 Samsung B-die

cicero s Well, changing global c-states from [AUTO] to [Enabled] helps boost clocks a little bit higher/longer for my 2700X. I thought the tip applies only to Ryzen 3000 series.

Here is the specs: https://www.kingston.com/dataSheets/...19PB3K2_16.pdf

It's 4000 MHz, so I know it will never run at that speed... but it's B-die so I should at least be able to push it around 3000 or 3200 MHz.

Of course it's nowhere to be found on the QVL. But it's kind of expected since the motherboard manual says up to 2933 MHz modules are supported.

Otherwise Corsair Vengeance LPX CMK16GX4M2B3600C18 which also are not in the QVL (3600 MHz). Price is similar.

There is also G.Skill Trident Z F4-3000C14D-16GTZ which are 3000 MHz but they're not very low profile.

Can you please confirm all of these three are compatibile?
Those all look like B-Die. You can use that link I posted to find any B-die set...then choose the right one for the right price. I'm running some GSkill Trident 3466, and I can get it to 3600CL14....and atm I'm running 3666CL16 at 1.380v....which to me is pretty good. I can run it at CL14, but I am missing one or two settings for it to pass TM5/HCI or any other DRAM test.

TBH, I had Corsair....hated it.(Don't let my bias about Corsair sway you. I just refuse to by anything Corsair, lol) I still have some Kingston(DDR3) in my back-up rig. It does really well. For me it's GSkill or nothing anymore. Seems to be the best imo.

Any B die ram I can find on Amazon.it is not in our motherboard QVL... should I pull the trigger even if it's not on the list?
Not sure if you have this site...but can make it a little easier to narrow your choice's:

I think pretty much any B-Die will work in our board if you manage to find some.
