I am trying to add 4 gigs of RAM to my existing 4 gigs. My PC is 5 years old and prebuilt, and I don't have all the specifications. It is a Gateway DX4840-11c.
Currently I have 2x2GB Kingston DDR3 667Mhz (which, according to a thread I found here, means I have 1333Mhz RAM speed?). I used CPU-Z to find out the specs and then found a RAM that matched it.
These are some screenshots.. And another.
So the stick I went with in the end was the Corsair XMS3 4gig. It had the same timings as my current RAM (9-9-9-24), and the same voltage (1.5v). Since it's the same speed and also DDR3 I figured it would work. From what I read on the internet, even though it was single channel it would work with the others, albeit at a loss of performance.
When I tried putting it in, I got a bluescreen saying "IRQL_NOT_LESS_OR_EQUAL". Here's a picture I took, if that's useful. I'm still not sure what the problem is. I read on these forums that I could try configuring the voltage and speed and making sure it's right, but going into my BIOS, there's no such options. Also, my BIOS is up to date. I also tried booting it up with just the new 4gig stick in, but when I did the computer made a horrible beeping noise so I quickly shut it off.
Can anyone help me? I don't know if the RAM is defective, or maybe just incompatible with my system, or whether it really needed to be dual channel (though I'm hesitant to buy a second stick to test out that theory, incase it really is incompatible.) Are there any tests I can run? I don't really know where to go from here. Maybe I missed something obvious, a lot of this stuff is new to me.
Thanks.
