...automatically? I have an ECS P4VXASD2+ (V5.0), purchased 2 x 512 mb pc2100 non ecc, unbuffered kingston ram ( kvr266x64c25/512). I have an addition 512 mb ( KVR133x64c3/512)2.53GHZ P4 , 128mb ati radeon 9000 pro, 2 port usb pci, creative sound blaster sound card It works perfect with just 1 stick of 512mb but when i add the other ram, it gives me the blue screen. I have no idea how to fix this...is it possible that i need to take out some of the jumpers on the motherboard? it also restarts randomly if it loads up to windows xp. can someone please help!!!?no. my computer uses both DDR and SDRAM4 slots total2 for the pc266 and 2 for pc133

try putting the ram in a different slot.

you indicated your two types of ram note the differencesKVR266x64c25/512 - x2KVR133x64c3/512 - x1You have two different types of Ram, Ram does not like being put in a computer in odd numbers if that number is more than 1.Yes windows has fixed the old problems with you having to have pairs all the time, but windows is windows, and if the ram is not EXACTLY alike sometimes, it will cause problems like what you are describing.Next, your computer is using PC133 ram from the sounds of your question, and now your trying to put PC266ram in its place. As well as combining PC133 and PC266 ram, bad bad idea.No offense, but you really need to find someone who knows what they are doing to help you purchase and install your new RAM. I hate saying this, but try the geek squad at best buy, or another similar group at another store, or a computer repair store so that your computer is not damaged, if they do it, they have to replace your stuff, if you do it, you have to replace it.

You have bought the wrong RAM. This particular motherboard only supports SDRAM up to PC133. PC2100 is DDR RAM that is not supported by your Motherboard. You should have checked the specs for your motherboard before you bought it.
