HELP! Added more RAM but computer doesn't use it

I have a Dell 4600 Desktop Pentium 4
2.8 gh dual processor, and originally (until today) had 256 mb ram.

(I have 4 slots for ram. It is DDR SDRAM /333mhz)

The ram is taking up two slots in my computer 128mb each.

I went to Best Buy and they gave me ram they said was compatible.
It is two thingys of 256mb DDR SDRAM (333 mgz)

I opened up the computer and plugged it in.

Easy as pie, right?
Wrong.

When I turned on the computer it heard a beep.

I get a message that says:

Alert! OS Install Mode enabled.
Amount of available memory limited to 256mb.
Strike the F! key to continue,
F2 to run the setup utility.


So when I hit F2 I get a crude looking menu that says:

Dell Dimension 4600 Series

and has all kinds of stuff in it.
The thing says there is 768 MB of ram in there.
So obviously it "sees" it.

So when I escape and windowns loads normally I go to my computer - properties and get that there is only 256MB ram.

But holy crap everything is loading faster.

What is going on?

How can I get the computer to recongize this ram?

BestBuy's "Geek Squad" wants to charge me $29 to tell me how to configure (over the phone!)

And Dell is worthless.

Help.

Hi becca77!

Check out this SITE for how to enter your computer's BIOS/SETUP and disable OS Install Mode.

To enter the BIOS/SETUP on your computer:
  • Turn on (or restart) your computer.
  • When the blue DELL™ logo appears, press <F2> immediately.

Also, some computers are picky about the RAM put into them, and that every stick of ram needs to be the same size & speed. What you can try to do, is to put your two 128 sticks in slots 1 & 3 and your 256 sticks in slots 2 & 4.

Determining the slots is if you are looking directly at the motherboard, then the slot farthest to the left is Slot 1 and the slot farthest to the right is Slot 4.

That is exactly what I did :)
Dell had made the 128MB ones in slots 1 and 3 so I snapped the 256MB ones into 2 & 4

And your link worked! It was so easy!!!!!

My computer recognizes the memory now.

How stupid of Dell to disable that from the factory.

Thanks a million. :tazz:

Yeah that is funny, because on the link I showed you it says the default is OFF for OS Install Mode. Maybe it's something buggy in the BIOS that automatically turns OS Install Mode on when you install new RAM. Sounds stupid, but wouldn't put it past Dell. There technicians are lacking in many respects. :tazz:

Glad to see it recognizes the memory now!

Oh yeah, you might wanna update your System Information in your profile, you no longer have only 256MB of memory. :tazz:
