I recently purchased 4 256 rdram pc 800 to have 1024 of ram to replace the 256 pc 600 I had. Now I installed all the memory but when I try to boot windows I always get a blue screen. Can't never get pass that. Machine does go into save mode tho, but that's all. I am running windows 98SE and Bios 09A. I removed 2 256 sticks. Now I have 512 of ram and computer does boot correctly without problems. But if I try to put in the other 512 of ram it won't boot. Can anyone please help me out here. Thanks
