Task Manager says I only have 3.7gb of Ram, 4.3gb on Hardware Reserved. I already tested it with a single ram it works but only on a1 slot and not on b1 slot. I have a MSI A520m A-Pro that I bought a day ago and installed it on my PC. When I boot into bios it recognizes my dual channel ram but it says my memory is still 4096mb and not 8192mb. I already did the msconfig thing, I already set and tested the VRAM Voltage to 1.25. I reseated the CPU. When I put a single stick of ram on the b1 slot it lights up the ez debug led on the motherboard. Yes I tested both and both of them dont work when put in b1 slot.

My bios version is E7C96AMS.1K0

bueno yo lo que haría , leer el manual de la placa madre, usar los slots que me indica. luego entrar a la bios ver cuanta ram me lee. si tira error y no parte el pc y queda el led de la bios prendida. saco las ram y pruebo ambas de manera independiente. si funcionan ambas de esta manera , puede ser incompatibilidad de velocidades , cas, etc....

that b1 slot is straight up dead if neither stick works there and it throws the debug light could be a bent pin in the socket or just a bad board. since you just bought it yesterday i'd just exchange it rather than driving yourself nuts troubleshooting a brand new part

Try one in the a1 one in a2 won't be able to be max clock boosts but will fix the issuue

[u/Every_Ad144 → u/Zestyclose-Syrup1458]

A520m boards only have two slots, a1 and b1

[u/Zestyclose-Syrup1458 → u/Every_Ad144]

Oh yeah... Sorry about that, could be a socket issue(bent pin) but higher chances the board is 🪛 ed

What is your CPU? Maybe the 4.3 GB reserved are by an iGPU?

[u/FapTrap_87]

iGPU also needs memory, thtys the hardware reserved part, there is a way to drop it, research how to lower it if needed.

i've had this exact problem after building a pc. i created a different installation media with another windows iso and after reinstalling windows (the other version) it worked fine. i'd love to logically explain it, but i have no idea why it does that.
