1 GB Radeon 6850 shows only 737 MB of VRAM in dxdiag Tags: Radeon DxDiag Graphics Product Last response: June 15, 2011 9:10 PM in Graphics & Displays Share kvothe June 14, 2011 7:18:24 PM Sorry if this is a noob question, but I can't seem to find an answer on google. Anyway, I recently built a new system, using this Radeon 6850 http://www.newegg.com/Product/Product.aspx?Item=N82E16814125353&cm_re=6850-_-14-125-353-_-Product and this http://www.newegg.com/Product/Product.aspx?Item=N82E16813130583&cm_re=msi_p67a_g43-_-13-130-583-_-Product motherboard. The problem is that dxdiag and other hardware scanning utilities say that I only have ~737 MB of video memory. Is this typical behavior or is something wrong? If needed, the whole dxdiag is here http://pastebin.com/DECfNApg More about : radeon 6850 shows 737 vram dxdiag mactronix June 14, 2011 8:33:19 PM How much Ram do you have and whats the Operating system ? Also does the MoBo have on board Graphics could it be reporting that ? Mactronix kvothe June 14, 2011 9:41:41 PM OS: Windows 7 Professional 64-bit RAM: 8 GB (both of those are right at the top of the dxdiag ) Anyway, while looking at the dxdiag thing again, I saw a more detailed description of the video memory than are shown in the GUI. Here's the relevant portion: Quote:Display Memory: 737 MB Dedicated Memory: 1008 MB Shared Memory: 3825 MB Is the actual 6850 memory represented by the dedicated memory portion? If so, I feel very silly Related resources Sapphire 7770 OC ED 1gb DXDIAG SHOWS THAT - Forum HD4830 512 showing as 1GB in dxdiag ? - Forum HD6670 1GB DDR5 . directX only shows 702 mb - Forum Dxdiag 7890 gpu - Forum 1 gb of ram shows 896 mb in dxdiag ? - Forum Can't find your answer ?

Mactronix Shpati June 15, 2011 11:30:52 AM Could be something related to shared video ram. kvothe June 15, 2011 2:03:13 PM It could be Windows aero, but the display memory shown in the dxdiag didn't change when I switched to the Windows Classic theme. Anyway, my mobo doesn't have an onboard video chipset. Here's the info you wanted: Card name: AMD Radeon HD 6800 Series Manufacturer: ATI Technologies Inc.
