Hi
so i recently bought 2 Macy (a vendor i never heard of) GT 730 2gb for my two low end PCs one core 2 duo and a quad core the cards seems to perform well but crashes whenever i play a heavy game these games runs well with 60 fps average but one thing is after i play for 10 minutes sometimes near 15 minutes the games crash so i began looking for the issue and it appears that if i use more than 1GB of vram the games instantly crash and when i looked online i found that my cards might be fake and with no way to limit the vram unless i can find a way to edit the vbios so the cards report only 1gb of vram

Can you take a pic of the gpu itself? Include all the back stickers and get a decent shot or 2 of the heatsink. Those numbers in gpu z look legit. A heat issue may be causing the shutdown, when I had a fake gpu I bought from china the heatsink itself would detach from the gpu die because the springs holding it were too weak. After replacing them it worked fine but was definitely a fake card, the hdmi port didn't even work.

There's a bios expert here that can probably help you in finding one, he'll need the pics I asked for.

Since the cards are doubtful, you need to remove the heatsink and get a picture of the gpu die, clean and board shot front and back and a close up of a ram chip.
