RAM Trouble

[вαℓυ]

Hello GTAS,

Good to see you again. I'm here to bother with you with a little dilemma I've stumbled upon. I had a 1GB RAM in my computer, wanted to speed things up so I ordered another 1GB of the same company. The thing arrived and I placed both RAMs into the slots(Only have 2 slots, this is an old computer), but my computer refuses to detect the second stick when both are inserted into the slots. Individually, both RAMs work but when put together, one blacks out. Computer works fine with both RAMs in, but the thing is it just doesn't read the second one. I had another 256MB RAM, and I placed it together with the new 1GB one and it showed up fine, it detected both with no problems. I don't know if I should return the product or not. Some help/advice would be nice, thank you.

Did you put it in the right way?

Which DDR is your first RAM? There might be a problem with your mainboard not detecting newer RAM's with the newer DDR series.

DDR3 RAM wouldn't fit in a DDR2 slot.

Make a bootable usb of Memtest86 and test it on your old ram by itself, your new ram by itself, then both together.  Also when putting ram in motherboard, make sure there's a space between them: - if you have room for 4 sticks of ram make sure they're installed like this: (|)  ( )  (|)  ( )  or in slots 2 and 4.  Also check timings in bios to see if they are the same.

That's what I was trying to say, sorry if my wording wasn't clear enough

Did all the things you said. Ran Memtest86 with the old ram, test passed and no errors, ran it with the new ram, test passed and no errors, ran it with both and test passed, no errors. But, in the test where I put in both rams, Memtest86 tested only one ram, 1023MB. I also noticed one thing in the Bios, suppose I put the new ram on slot 1, it works fine individually and in the Bios it shows up in Memory Bank 1. When I put in the second ram on Slot 2(the old ram), the Memory Bank 1 in the Bios shows up as "Not Installed" and it only shows 1024MB on Memory Bank 2, the old one. Oh and I checked the Product Specifications for this PC, maximum 2GB allowed, so it's not that.

Oh and both rams are DDR2

*Useless advice ahead*

Did you clean your PC? Or rather is everything free from dust?

Indeed, it's dust free. I even cleaned the RAM slots with a little brush.
