This is a bit nuts. The MSI card is GeForce 210-MD512H: http://www.msi.com/product/vga/N210-MD512H.html#?div=Specification ...witch is basicaly fanless budget MSI GeForce 210 with 589/1024MHz clocks and 512MB DDR2 ram. All in all a budget card to do the work required and that it is. However I wanted to use it in my Sapphire "Grouper" A9RX480 mobo (that is ATI chipset RX480-450 for SB) and it refuse to post. When I plug there my old good PNY GeForce 7800, then (even w/o the external power cable connected - DOS only, true) everything seems working out nicely! Now that is a bit insane. Any suggested bios settings to make the card work? Yes, it is claimed to be 16x PCIEx speed... shall I try 8x? Okay, tried 8x, no difference Some settings are really interesting - how about these? LTD Configuration - Enabled Upstream LTD Bus Width - 16bit Downstream LTD Bus Width - 16bit LTD Bus Frequency - Auto (1GHz, 800MHz, 600MHz, 400MHz, 200MHz) (I know, this have more to do with the CPU memory controler that GFX card, but who knows?) PCIE GFX Core Payload Size - 64Bytes (32Bytes, 16Bytes) PCIE GPP Core Payload Size - 64Bytes (32Bytes, 16Bytes) NB-SB Port Configuration - Default (Enhanced) PCI-E GFX Link Width - x16 (x12, x8, x4, x2, x1) Assign IRQ For VGA - Enabled (Disabled) ...any suggestions? MSI seems inclined to claim that this is just a "compatibility issue." They are probably right about it. Is there any bios fix for this card, or I'm completely helpless in making it work in my Sapphire A9RX480 mobo? BTW, where MKV tech net guys go? There are some talk about VGA bios mods, perhaps they can help me out with this...? Anyone know?
