Optiplex 740 RAM ISSUE

post #1 of 10
Thread Starter 
Ok, so I have an Optiplex 740 with the latest BIOS, 2.2.7, and an Athlon 3800+. I have 4 stick of 1GB RAM that are guaranteed working with the computer. Now, when I add any RAM that is 512MB or 2GB per stick, the thing won't boot. Not even if its mixed with the working RAM. The RAM is put in the slots fine, so no problem there. Can anybody help?

Clear CMOS, then try booting after installing RAM.

I've already tried to clear CMOS twice, swap the sides RAM are on, and jump the jumper.

Bump, this PC is starting to piss me off. I'm only getting 4 sticks of RAM that will work, and every other RAM stick, identical in specs or not, won't work. Seriously, I need help.

Hit yet another roadblock. Decided I just wanted a working computer, so putting the working memory in and-- nothing. Just the 3-4 error code and jet fans. Seriously, this computer is f*cking with my head, everything I do ends in a problem, and something that should work ends up not working,

What slot did you put the working ram into?

You must reset the cmos each time the pc wont start after changing components.

The jet fans means there is no ram detected

With these dells there should be a code of some sort in light form with either numbers or letters

The leftmost slot looking at the front of the computer.
I am resetting CMOS each time, and I get the 3-4 light code, which means RAM configuration, but Dell says to re-insert RAM, or contact support (which is basically this site since I doubt Dell is going to cover a PC from 2007).
