I have been fighting with my present system.First I changed from a X800XT to a X1950 PRO..All was fine.Then tried to put 4 gigs of ram in and system went haywire.Took the CPU out and was cleaning it and broke a pin,got another one(and this is killing me getting down to work on it)..Same thing,RMA another one and it still does the same thing..One long beep and will go to the first post screen and no farther,keeps giveing one long beep.Its back to 2 gigs of ram..Any ideas?
The last PC I was on, I upgraded to 4 sticks.. got very unstable until I bumped the RAM voltage up a notch. Everything was fine after that.
If you broke a pin cleaning your CPU, you're doing something wrong. Pretend you're a surgeon - figure out what you need to do before cutting open and poking around inside. Randomly unplugging parts (I'm guessing trying to do it without taking everything apart, too) is bad business!
You need a 64 bit system to use 4 GB of RAM. A 32 bit system will recognize 3 GB at most.
If you have double sided memory the other two modules will not work normally.
sigh. we all know that 32 bit os can only see ~3.5GB of ram, that is not the issue here as he is have a problem before the os even starts to load. As ScubaGeek said it is most likely one stick that is bad. If not, and your not useing vista, just return it for your money and go out and get pissed
