post #1 of 33
Thread Starter 
Hello, I want to add some ram to the vram of a 250 gts for GTA IV, I see in another forum (no response, two years old thread) a guy doing this to improve performance and play higher resolutions, how the hell I can do this? I searched in google but not response, is for the rig that I have below.

Nope.

Get a better card if you want better performance.

You can't just add vram to a card, it is not like desktop ram. It is actually hard wired into the PCB of the GPU. Plus it would be immensly difficult as well as time consuming to perform such a task. And if you were capable, you should be rich enough to buy a 590 no problem. thumb.gif

1) Find/Salvage compatible higher density GDDR3 ICs.
2) Remove the existing ICs
3) Ball grid solder on the new IC (good luck with this)
4) Modify existing BIOS.

Profit.... or then realized that you wasted money and hours of time when you could have just bought a new card. biggrin.gif

You can add vram just as well as you can add headlight fluid to a car. You can't.

tell asus and other manufacturers that, sometimes they actually add memory to cards and sell it as *gbs of video memory even though the card can only access what the oem cards ship with... not like the difference between a 1.5gb and 3gb 580, like a 460 with additional ram glued/soldered onto it but not actually connected to anything on the card.

Umm, show an example? If they actually do that it's news to me.
