You probably have the wrong type of memory, wrong placement or the wrong amount. http://www.crucial.com/store/listparts.aspx?model=Dimension%204600 will tell you what you can use on that model. Also you should not mix speeds of memory or the new faster memory will run at the slower memory's speed. The 2 128 chips are useless--leave them out. Make sure you check which is slot 1, 2 , 3 & 4. They are not next to each other. Check your manual. Slot 1 is besides slot 3. So the slots are top to bottom-- 1 and 3, and 2 and 4. Make sure to put the new memory in slots 1 and 2, leave 3 & 4 empty and reboot.
You system will support up to 4 gigs of ram either PC2700 or PC3200 DDR Ram non ECC
I would say first pull the old ram out and just try the two 1 gig sticks. They need to be in slots 1 and 2 .
What might be happening is the mixing of the ram speeds will cause the PC3200 ram to throttle back to the speed of the PC2700 ram and it may not like that.
There is a new bios update A12 which you can download from HERE
Thanks for the help guys, all I needed to do was remove my cmos battery and put it back in. Doing that restarted my clock but it also now shows 2.25 gb of ram being used and things are running alot faster now. I will keep the two 128 mb until I'm able to get two more 1 gb sticks.
