Okay ive been trying to fix this all day. I bought these 2x 4GB ram sticks and i cant get both of them to work at the same time. i put both of them in and it runs soooooo slow. i am using one now and i can run on this 4GB stick and it works in each slot for the RAM but i can not get them to work together. They are Corsair RAM sticks. When i use both my computer sees that it has 8GB but will run so slow and it tells me i have up to 8GB of RAM free to use and it just lags all over. well here i am i have messed with the BIOS which wont let me change anything also i have Tried putting one in at a time and still nothing. Any suggestions?
