Hi, I've just recived my new memory today and installed it and I could'nt get a video signal. The exact message was " No Signal Analog Signal out Sleep..." I didn't know what the heck was going on. I thought my ram was defective. but then I took a closer look at the ram and it turns out Zoomfly sent me the wrong one. I have two ram slots on my motherboard the ram that I already had says VS512MB400 on the white sticker. The new one zoomfly just sent me says VS512MB400C3. I'm not able to boot up using both chips at the same time but I am able to if I only use one of them. Dose my memory not work because of the different Cas Latency of the new chip? Is the any way I can get both chips to work together?
