Hey everyone, i used to have my PC with 4Gb of ram and an AMD 64X2 3800+. However, earlier this morning i installed a 5000+ black edition (Ocd to 3.0Ghz :D) However, the machine would boot but the monitor would just stay in standby, i couldnt see anything. After much paninking and trying loads of things i realised it booted with 1Gb of ram fine, the 2Gb fine, then 3Gb fine, but the moment i put in the 4th stick it boots but the monitor does the stupid standby thing. Seeing as i have Sli i need 1Gb of ram just to adress the GPUs, so my PC eats up ram. Does anyone know why it suddenly does this??

Thanks, Jon
