Overclock & vRAM

post #1 of 7
Thread Starter 
Hey. I like to overclock my two MSI Radeon R9 290X video cards a lot with high end gaming like BF4 and AC4 but I was wondering if I could do better. Is there a way to allocate some of your motherboards memory and turn it into vRAM that your graphics card can use? I have 16GB of RAM and wouldn't mind allocating one of the 4GB sticks to my card to have 12GB of mobo RAM and 8 of GPU vRAM. Thanks! thumb.gif

No, that's not possible. I don't see why you'd want to do that anyway. The R9 290X has 4gb's of VRam, and even if you game at 1080p+ resolutions, you still won't be using all of that 4gb.

What resolution do you game at?

Most of the time I'm on my triple Dell U2713HM's at 2560x1440 which is 7680x1440p but when I play games like NBA 2K14, or SC:Blacklist , I play on my ASUS PQ321Q Monitor which is 3840x2160p and I've been saving up money for maybe two more and replace all three of my Dell Monitors.

Well, like Trojan said you can't add more VRAM the way you asked I'm afraid. At that resolution it's natural for high VRAM usage of course.

Windows already does what you describe in the form of shared system memory; your RAM will be used once VRAM is exhausted. This is only done passively though, and rightfully so, as system memory is much slower than the dedicated on-board video memory.

Okay, at 7680x1440p & 4K, how high does your Vram usage go?
