Need help in troubleshooting. Current specs are on the right ->

Windows randomly decides not to use the full 16GB when I moved my PC around to vaccume dust on the floor. It uses half and keeps the other half as "system reserved". I have tried some of the solutions where you can set the hardware reserved memory in windows: These solutions did not work. BIOS have always been able to detect 16GB however.

I have tried attempting to boot with 1 RAM stick. Initially the comp refused to boot with stick A, so I labeled it "faulty". But in later attempts to test it again, "faulty" stick works.

RAM test:I used the free version of https://www.memtest86.com/ but since it's a free version, I can only test it 4 rounds at a time (I'd leave it running like 2 days on infinite loop.)
Testing both sticks individually returns no errors, even when I tweaked the frequency to 2933MHz.

Got tired of testing, so I eventually left "Faulty" RAM stick in. Haven't been doing any form of intensive computing recently anyway, so I made do with 8GB. All the above was over a period of around 1-2 months...?

Yesterday night decided to try using non-faulty stick. Refused to boot.
Today, decided to try again. using Stick A and stick B individually refuses to boot. Decided not to waste time on it -> puts both back. Windows uses all 16GB :s22: :s13: :mad: _|_
I cannot be bothered to change the timings and frequency back to 2933.

I have tried using different RAM slots as well. No conclusive results to draw.

So, with 3 pieces of hardware suspected faulty, what is the probablilty of Mobo or either RAM stick to be faulty? How do I test?


For future reference, when I change my comp:
Mobo: Gigabyte AB350 Gaming 3
RAM: Corsair 16GB 3200MHz Vengeance LED DDR4 (CMU16GX4M3200C16R) (Running at 2933MHz)

Try the free trial of passmark burnintest if memtest picked up no errors

From your post it does not seem like mobo or rams faulty.

More likely to be the rams are not inserted or seated properly into the slots or the contacts between rams & mobo need to be cleaned.

Failure to boot does not mean ram is faulty, ryzen gen1 is known to be very picky with ram.

Worth a read if you want to find out more, free memtest inside the calculator too.

You can try running at DDR4-2666 as anything above that is technically an OC.

Sounds like your MOBO RAM Slot or RAM got problem.
That's why I only use a Single RAM Slot.
Can be a pain trying to run RAM in Dual Channel.

there are certain combinations of slots to use for dual channel operation. make sure you follow them. maybe it's just some kind of compatibility issue. maybe caused by the 2933mhz. sounds like after you got lazy to set it to "2933", it kinda worked.

Updating my old thread, in case anyone has similar issues: Went to Convergent in Janurary, and got my RAM replaced with Corsair Vengeance RGB PRO 16GB kit (CMW16GX4M2C3200C16). Forgot to ask if they managed to test my old RAM for fault. No issues since then. Didn't bother to adjust RAM frequency to above the default 2133MHz however.

My problem TL;DR: no observable pattern in memory issues, RAM test yields no errors. Mobo has always been able to boot, so gambled on the 50/50 probability that RAM was at fault, RMA ram, ok since then.
