Usable memory less than installed!

The thing is that the problem must have been there from the beginning because when I put in the 4 modules it doesn't start. It makes two attempts and starts again when the check shows "F9", then it gets stuck in a loop and I have to manually restart it, then Windows starts up.

F9, I've looked in the motherboard manual and it says: <F9> Recovery capsule is not found.

Until now you hadn't mentioned that putting in the 4 modules it wouldn't start.

If the computer is giving you false starts and restarting several times before it can actually load the OS, there is a memory configuration problem.

Go into BIOS and load the default options, and try booting with them.

If it's no longer reserving 16GB, you've found the problem, and you can keep testing until you find the fastest memory configuration that allows you to use it without that limitation.

Perhaps that kit isn't designed for Ryzen.

Cheers!

PD: If your memory is this, it shows up as tested for Intel platform but not for AMD, so activating the XMP profile is likely to cause problems.

It has always given me boot problems with the 4 modules. No matter if I put the default options or not. It stutters with the 4 modules, what I don't understand is why 2 don't and 4 do... This kit is not for amd, it's for intel... I bought it because the ones that were for amd were very expensive and very scarce at the time. Looking for someone who said it worked with my configuration... and I bought them. They have the famous samsung b-die.

Thanks Fassou, Salu2!

@scherade You'll have to play around with the timings by hand to get it to work, but success is not guaranteed.

Muchas gracias Fassou

I think I'm going to try a memory kit that the manufacturer says is fully compatible with my setup and if they work well I'll try to sell these I have, because I can't use them at 100% or so it seems. From G.skill they responded with this:

Please also understand that Ryzen platform does not natively support odd number CL timing (such as CL 15, 17, 19…etc) it will automatically adjust to the closest even number, this is why we did not include any odd CL timing memory kit into our AMD motherboard QVL.

Well, I think I've ruled out that it's a software problem for sure, correct me if I'm wrong... I've booted the PC with a USB with Hiren’s BootCD PE x64 (v1.0.2) and Windows recognizes the memory exactly the same.

Now I want to investigate if there may be one or more damaged modules because there's one in particular that can't be read with any program the specifications... neither with Windows nor with Thaiphoon Burner, cpu z,... none and I've tried many.

Is that already an indication that it's bad? Separately, I can get them all to work at 3200mhz, although the one I mentioned sometimes doesn't even start the PC.

Thanks and Salu2!

Well, in the end, after investigating here and there and with the help of the Thaiphoon Burner, I found the origin of the problem. There was a module with the perfect SPD and it was the one that worked without problems. In the rest, the SPDs were corrupt, or a part had been erased or it had been changed. The reason, I ignore it. The modules are now in Holland in an RMA to be restored. I would have done it myself, it doesn't have much mystery but I needed the paid version of the Thaiphoon and that came out more expensive than sending them to Holland. Because the cost of shipping had to be paid by me. G.Skill has a lifetime warranty.

@scherade Don't forget to let us know when everything is resolved, how was the RMA experience

Of course. I'll tell you. From what I've read, it seems they don't work badly... we'll see.

I forgot to comment... until now. I did well with the RMA, almost a month without the memos. They sent me other modules, they didn't fix whatever was wrong with mine. These work as they should. The thing is that the heatsinks are ¿badly glued?, or at least not as before... They move with little effort... And they could come off very easily. In any case, I have them working without complaint.

Greetings and happy holidays.

@scherade if it's any consolation some manufacturers are very "majos" I bought a patriot Viper black Manba ddr3, two modules of 8gs total 17 gs with XMC activated it works at 1866. When I bought an identical pack it only works at 1600.
According to the official patriot website it's normal... They don't guarantee that they will work if it's not a pack of 4/ 8 gs
Sends cojones...
Regards and Happy New Year
