Upgrading RAM on a Dell Studio 1749
Basically, I'm trying to upgrade the RAM from the current 2x2GB chips -these- to a couple of 2x4GB chips -these- and I've been having issues.
The symptoms are:
-
The laptop boots to bios, and to any OS loading screen, tried with Win7 on the HDD and Ubuntu (with a live disk), both 64-bit versions.
-
After the loading screen for the OS the laptop reboots.
I tried before with a couple of other chips (that showed the same symptoms) that when placed in my other laptop reported a speed of 1600 instead of the advertised 1333, so I figured that was the issue.
This is really odd, as the 4GB chips appear to have the exact same specs (other than the size) and therefore should be compatible, and various forum posts confirm that 8GB is the top limit of memory for this system.
The 8GB RAM works fine in another laptop I have access to and reports back all the right specs (unlike the first pair I bought).
I've also checked the BIOS and it is up to date, along with the motherboard firmware.
My only idea is that somehow the current RAM is underclocked, as the only mention I can find anywhere is thissaying that the 1749 is only compatible with 1033/1066 speeds, BUT the chips in there currently are 1333 and report that on other computers.
I'm really confused, and have tried a load of different avenues with no success. Has anyone got any ideas here?
I've put up the dxdiag here if it helps: http://pastebin.com/AkVf09Mt

According to your spec sheet you should be able to run 1066 MHZ sodimm DDR3 memory in your laptop. Not all memory is compatible with Dell Laptops and that may be your issue. If you are looking for compatible memory I would recommend buying from www.crucial.com where they guarantee their memory to work in your Dell computer.
