Tried everything but it will not read new RAM

Compaq / Sr2050nx

Specs: Windows XP
So this is my setup, its just a presario sr2050nx. Has 2 memory slots for RAM (up to 2GB). I bought a 2 pack of 1GB RAM (2 gb total), and put it in the slots but only 1gb is read by the BIOS and system. So far I have:
- re seated the sticks of RAM (about a dozen times)
- tested the memory slots individually (both work)
- tested the sticks of RAM individually (both work)
(put each one in each slot and booted up the comp, it worked just fine. Just not when i put 1 in each slot, it just reads 1gb instead of 2gb)
- reset the cmos
- ran a windows diagnostic for memory
- used cpu z and it claims to have the 2gb
(even though bios wont recognize them)
and it still wont work!

My guess is that for some reason instead of going into dual channel memory mode it sticks to single channel mode. But that shouldnt be a problem because the 2GB of ram are exactly the same aannndddd there are only 2 slots so i dont have to worry about matching the right slots to go into dual mode. And before you say anything else, yes they are compatible with my motherboard. Ive checked everything over and over and it still doesnt pick up both GBs. What do i do?

Oh and BIOS says that the 'memory bank 2 : not installed' but idk what to do to fix it

You must have removed RAM to be able to try the new stuff...did you try one new + one old? Does your new RAM run at 1.8v?

I had a 1gb stick before so instead of risking a mismatch I bought 2 new sticks. It came in a 2 pack so it should work. And yes it does run at 1.8V

Well, did you try one new one + the old one?

Im really running out of options here, I've tried everything imaginable

Sounds like your second memory slot is defective. Can you get memory to work in either slot when using only the original stick?

Thats what i thought too but when i move the old memory to the 2nd slot it still boots up and recognizes that. I even tested both slots with one of the new sticks and it boots up. So i guess the slots arent defective

Verify that you are fully seating the second RAM stick. If there is something in the way it may be difficult.

I'd have to move all these cables out of the way to get a clear picture but trust me I am seating it all the way. When i push down both sides click in

This isnt the first time i've changed RAM(I usually upgrade my friends computers) Its just the first time a computer wont recognize it.

Then all your RAM is not compatible with your board. Go to crucial.com and use the online scan to determine what RAM is compatible. May have something to do with the size of each chip on the module.

The density may be too high.

After doing some research on high/low density ram I noticed that my old ram was a high density ram. Which explains why when i combined one of the new sticks with the old one they didn't show up (cant mix high and low). Also, one of the new sticks (even though they're the exact same type/brand) only has 8 chips on one of its side. So im guessing that its a high density ram, while the other new stick is a low density ram. Which also explains why they weren't compatible with each other. Thanks for the tip OtheHill

I'll switch out the low density one at frys and make sure the one i get is high density

Hope this works

I couldn't find much info on that board so I can't say for sure that your problem is with low density. Just as likely the board requires low density RAM.

What kind of processor is running in there? Do you know the age of the computer?
