Am I seeing that right? 4GB of VRAM? I have the MSI 390X(It has 8GB VRAM). Same stock clocks. I managed to get about 1150ish and 1625 VRAM. I havent really pushed it any at all as this thing crushes anything 1080P I throw at it. I have seen some get over 1200/1700 with them. I do think they added some volts to get there. YMMV. Let us know

they made 390's with only 4GB vram but they are aimed at asia markets only

but it seems that the benchmark program is just reading it wrong

After deciding to get curious and test my card it too shows only 4GB of VRAM. So its just the program misreading the card.
