I'd like to add additional memory to my new HP Envy computer - and I have watched several videos, looked inside, and used the hwi_586 utility to see where the installed memory is, and I still have a question. Business PCs, Workstations and Point of Sale Systems.Printer Wireless, Networking & Internet.DesignJet, Large Format Printers & Digital Press.Printing Errors or Lights & Stuck Print Jobs.Notebook Hardware and Upgrade Questions.It would seem that the new RAM is not compatible to the XPS 400, return the memory for credit and go HERE and use their System Scanner and buy RAM that's certified to be compatible with your computer. (thingies is a technical term) And two have black ones. I have four ram slots on my motherboard, two have little white end thingies.

The new ram sticks are both dell bought as a set so I would think they would be a matching pair. Then I thought maybe I didn't have them seated properly or something, so I tried again with the same results. Took the old ones out popped the new ones in and all I get is a loud beeping sound from the computer, very alarming! So I took out the new ones popped the old ones back in and everything worked fine again. This configuration seems to be working fine, but every body needs more ram right? I bought 2 more 1 gig sticks and tried to install them in place of the 2 512's. Currently I have 2 gig's, 2 512 and 1 gig stick. I have a problem with installing new ram in my xps400. If you need additional help please post back, Best, So my guess from your post is that your system will only handle 3 GB, so put your 512s into slot 3 & 4 and your 1 GB into slot 1 & 2, and you should not get the beep. The 32 bit systems will only handle 3 GB of memory, no way around this! 64 bit systems will handle 4 GB and up of memory, depending on your motherboard. What is your OS, opperating system? Windows Vista? Windows XP? and what is your version? 32 bit or 64 bit? When you do not put them into the slots as pairs sometimes you get faults (beeps, or sounds from the MOBO which means, this won't work) RAM pairs must be placed into the matching DIMMS, so your 512's go into matching color pairs. The DIMM closest to the CPU processer is traditionally labled #1 and the third one over which will be the same color is #2, the second DIMM is traditionally labled #3 and the fourth one over which will be the same color is #4, does that sound confusing enough? Oh, well, that is just the way it is. Regarding your white and black thingies, you are referring to what is commonly called DIMMS, that hold the RAM in place. Good Morning coramonster and welcome to the forum,Ĭongratulations on your first post and do take the time to wander around, this can be a fun place to discover and learn.
