Does RAM voltage matter to the Graphics card?

My computer.....MB MCP73PVT_sm, Intel duel core 2.53 Ghz, 2GB Ram DDR2 800 Hz, power supply 750w, video card GTX 650. I noticed the BIOS is showing the RAM voltage at 1.9v, but the RAM is rated for 1.8v. If I use 2 sticks of RAM, the video card crashes my computer. I get the BSOD. If I use 1 stick of RAM, no problem with the video card, everything is fine. The board can handle 4 Gb of RAM, but right now I can only use 2 Gb (1 stick). Could the RAM voltage be causing the video card to crash the system? (1.9v instead of 1.8v).

How have you concluded that the GPU is crashing the PC? It sounds like 2 sticks or RAM crashes the PC. The 1.9v shouldn't cause the PC to crash, any decent MB should handle that. Have you made sure the second stick isn't bad? Why are you running them at 1.9v anyway? Have you tried 1.8v?

My old card was a GT440. That card worked fine with 4 Gb of RAM (2x2GB sticks). My new card works fine with just 1 2GB stick, but if I use both 2 GB sticks I get the BSOD. I've tested both sticks and both RAM slots....they are fine. I can put either stick, in either slot, and the computer is fine, with the GTX 650 card. If I put in BOTH sticks, I get the BSOD.
