Laptop won't recognize new RAM.
16 minutes ago, ilkork92 said:Hello there.
I have an old Toshiba Satellite C660-1MK (full specs here) which came with 3GB DDR3 1333MHz RAM pre-installed (1x2GB this one, 1x1GB this one which also has a manual). Manufacturer's website says RAM can be upgraded to 8GB max DDR3 1066/1333MHz. So I went and bought 2x4GB this one, to upgrade it. The problem is that, while BIOS recognizes both modules together (total 8192MB of RAM), I can't boot into windows. It gives me a white dash on top left corner. And the weird thing is that, if I mix one module from the old ones (say the 1x2GB) with one module from the new ones, I can normally boot into windows, it now recognizes 6GB of RAM. But if I only use one module from the new ones, I get the same "dash on top left corner error". So, why can't I use both modules of the new RAM at the same time and have 8GB RAM?
The only differences I can see are:
-old ones have PC3-10600 and new ones have PC3-10666 (but isn't that just marketing?)
-old ones have 4 banks on each side, new ones have 8 banks on each side, check images below. (by banks, I mean those black rectangles in the modules, excuse me, I am not that tech savvy)Other than these differences, everything else is the same, DDR3-1333MHz SDRAM, SO-DIMM, Unbuffered, NON-ECC, CL9, 204 pin, 1.5V.
So far, I've tried:
-replaced old CMOS battery with new one
-made a fresh install of Windows 7-64bit
-checked both new RAM modules with Windows Memory Diagnostic (I did it by mixing one from the old modules with one from the new ones)
-every driver is updated
My BIOS version is 1.50 from 15/12/2011 (15th of December 2011) and manufacturer's website says that the last modified bios version is 1.50 from 14/02/2012 (14th of February 2012). I haven't checked that yet, didn't update it, but, could that be it? Why give it the same name (1.50)?
Some images from my BIOS settings (while the new RAM sticks are inserted) here.
Some images from system properties, msinfo32, dxdiag (while one from the old modules and one from the new ones are mixed) here.
Images from HWInfo (while one from the old modules and one from the new ones are mixed) here.
The old modules and the new ones here.
The problem Is that the 10666 is different from the 10600. Try getting PC3-10600 ram. That seems to be a laptop related issue because on a desktop the 10666 or the 10600 both work(and I'm talking about desktops not laptops and it's just an example). I know this because I've had a similar problem like this one. Ps(to everyone replying) : don't come at me saying that pc3-10600 is the same as pc3-10666. I know they are but only in desktops. Some laptops do work with 10666 but others don't.
