anyone ever heard of a ram stick losing nearly 3/4 of its available space?

Hi all , I've got an AMD athlon 3000g with 8 gb of ram and an onboard which uses 2GB of ram , So I was overclocking my ram , mostly adjusting timings slight bump in frequency just to get a slight bump in performance , then suddenly booted my pc into windows noticed I only had 5 GB of ram total 4 GB usable (IGPU reserved 2GB ) , so I looked under CPU - Z and its reporting 1 stick which is 4GB as a 1GB stick , changed now its reporting 512 but still have 5GB , so im just wondering anyone ever heard of such a thing before? 3/4 of a ram stick not functioning anymore?

Odd..

I think you should reset your bios and go from there. (assigning 2gb of your mem to the iGPU is a bad idea btw)

yeah tried that already , didnt do anything but thanks for the tip , wish I could get it working again .
why is it a bad idea ?

I've heard that , but noticed much more lag , frame drops and freezes when I set it to 1GB even tried 512MB was even worse,

It's certainly possible for PCBs, connectors, or individual DRAM ICs to fail in a manner that leaves the part partially functional.

I would try the DIMMs one at a time, in each slot, to confirm that it's actually some sort of hardware failure and isolate it to a particular DIMM or slot. If you're still missing memory regardless of DIMM or slot used, it's probably not hardware.

Remove and re-seat the RAM modules securely into their slots. Due to repeated heating and cooling, expansion/contraction RAM modules can "jack themselves up" high enough in the socket so some pins might lose connection. Often, just re-seating the RAM modules can resolve this.

interesting yeah tried switching slots , still the same amount of memory available , So the ram has failed , its just strange normal ram completly fails never heard of ram half failing before , anyway thanks for the help , time to get an 8Gb stick I guess .

Yeah I did try this , made no difference , sounds crazy but since the ram wasnt functioning I even tried baking it in the oven , worked for my old GPU for about 6 months , so thought it might bring the ram back to full use , sadly it didnt work , ram still works though , just reduced capacity

Baking parts in an oven is a really imprecise way to reflow solder balls to fix fractures. If the problem is on the actual silicon, or a bad trace on the PCB, it can't do anything.

Memory prices aren't that bad at the moment. If you're certain the memory itself is at fault, replace it.
