Memory Issue

I have a Dell XPS 720 that is 4 years old, currently has 2GB of RAM with Windows 7 64-bit. I just bought http://www.newegg.com/Product/Produc...-209-_-Product and when I installed it I got the 1,3,4 diagnostic lights on my computer (which has no code description in the manual). I took one out, while leaving the other in the 1st slot, turned the computer on, and it worked. I switched them, with the 2nd stick in the 1st slot, and it worked. Then I reinstalled them both (1 in 1st, 1 in 2nd slot), and got the diagnostic lights again (no POST, BIOS, nothing on screen). I reinstalled the original memory this morning, and it's working fine.

A scan by Crucial says that my computer will accept PC2-6200, which is what I have, where I'm replacing PC2-5300 sticks. Does anyone here have any insight as to why the two sticks won't work for me?

Thanks in advance to anyone with any ideas.

My first question is:

By "1st slot" and "2nd slot" do you mean slots 1 an 3 on your motherboard? Your manual points out that (like most dual channel capable motherboards) that for proper set up two sticks should be in the first and third slots. (You don't know how hard this was to learn coming from before dual channel motherboards... ;-P)

They should have the same color "clips" on the ends to hold the sticks in place. If your black and white manual is any gauge, and I'm not saying it is, they should be white clips.

Second, and perhaps final question, is:

Are you sure they were both seated properly on the board? I have worked on motherboards that took a lot more pressure than I was comfortable using to get memory sticks to seat properly.

I made sure they were in the correct slots, the 2 with the white clips. I'm also pretty sure they were seated correctly...I did the exact same thing each time, and the only times I had a problem was when the 2 new sticks were in there at the same time. I'm working on updating my BIOS right now to see if that helps. Other than that, I'm gonna have to contact GSkill to see if they can help at all.

The 1 3 4 code is no ram detected and memory failure.

Have you tried placing them in the other two slots? Usually as long as you aren't installing just a single stick then either paired slot combo will work.

Well.

With that, my knowledge on the issue is spent. Sorry Bohmfalk. I'd say give the suggestion from Mandu a try. Or, follow through with your plan to contact G.Skill.

I can tell you, that I have read reports (not sure how accurate) that faulty memory can fail when paired, and work fine when single. For what that is worth.

Did you simply try and swap out the old RAM for the new? Worse case you now have 4GB where you once had 2GB.

That's actually what I was trying to do....get rid of the old, put in the new. While updating my BIOS got the computer to start up with the new RAM installed, it wouldn't make it passed the login screen, and at best restarts while typing in my password. Most often, however, it either freezes at the beginning of BIOS, or right after. I'm thinking I might have to see if NewEgg will let me replace my new RAM with something from Crucial (which I've been told on the Dell forums is guaranteed to work for these computers).

Well they should definitely both go in either the white or black clip slots. The clips should be all the way engaged. And for extra measure I will usually (gently) rock/wiggle the memory in the slot to make sure it's seated very well. The manual does indicate that the memory you bought should work. So if it's incompatible, it's for another reason.

But before you send it back, conacting G. Skill seems a good idea. They may have some ideas.


It is known that there are an infinite number of worlds, simply because there is an infinite amount of space for them to be in. However, not every one of them is inhabited. Therefore, there must be a finite number of inhabited worlds. Any finite number divided by infinity is as near to nothing as makes no odds, so the average population of all the planets in the Universe can be said to be zero. From this it follows that the population of the whole Universe is also zero, and that any people you may meet from time to time are merely the products of a deranged imagination.
