GPU VRAM inconsistent

[theeighthbyte]

My GPU (Sapphire Radeon HD 7850 OC edition) is supposed to have 2GB of VRAM, but according to DXDIAG, it only has 1765MB. Is this normal or has some of the VRAM been damaged somehow?

dxdiag gets that reading wrong all the time... if you have a 2GB 7850, you have 2GB vram
