taser owl Posted December 24, 2013 Share Posted December 24, 2013 I have a Toshiba Satellite C660-1E2. Currently it has 4GB (2x2GB) of RAM. I decided i needed an upgrade and so i used the Crucial memory advisor to find out whether i could increase the RAM. They recommended an 8GB kit of (2x4GB). I took the information of the RAM they recommended and searched through the web to find what i needed. I picked up some new (still in original packaging) Corsair kit which i matched up the information on. I installed the new pieces and once everything was put back together i switched it on. In the BIOS, the new memory was recognised. However, when going through the start up, it gets to the windows loading page and the laptop freezes up. After seeking the advice of my grandfather, i replaced the old memory back in the laptop and everything worked fine. After checking through the specs again i found that the crucial website recommended memory for 1.35V and the pieces i have bought are 1.5V. Other than this every other number is the same in the specs. However, i have been rooting around trying to find out what the motherboard is in my machine and so have installed a utility called CPU-Z, the memory modules (the current ones) are all running at 1.5V. I'm rather perplexed about the whole situation, if anyone out there can advise me it would make my christmas. Link to comment Share on other sites More sharing options...
peanutz94 Posted December 24, 2013 Share Posted December 24, 2013 What is the xact part number of the kit you have?> Did you reset the laptops BIOS before adding the new memory? Did you check Toshiba's site for any available BIOS/FW updates? What CPU is in your LT? Link to comment Share on other sites More sharing options...
taser owl Posted December 24, 2013 Author Share Posted December 24, 2013 Ok, so the part number of the kit is CMSO8GX3M2A1333C9 I have tried resetting the bios from within, however, i am currently searching the web for some schematics for the LT, possibly reset by cmos jumper. I may well get round to it later on tomorrow. The CPU is Intel Core i3 380M Link to comment Share on other sites More sharing options...
peanutz94 Posted December 24, 2013 Share Posted December 24, 2013 I have a feeling I the issue is going to be the size of the memory chips used to make the modules. Is there a version number on them? Or can you see how many chips are on the module itself? Link to comment Share on other sites More sharing options...
taser owl Posted December 24, 2013 Author Share Posted December 24, 2013 Ok, the numbers on the chips are as follows - 512M8DCJG ELB0301347. That is on all the chips, the two modules also have separate numbers on their chips The first one is F328X8BR644S The second one is F334X8BR7401. Each module has a total of 8 chips, 4 on each side.

peanutz94 Posted December 25, 2013 Share Posted December 25, 2013 That what i thought. They are 512mb chips and your laptop with an I 3 processor is going to be limited to memory made with only 256mb chips. So the new Corsair memory would be incompatible.

JKeifer Posted December 25, 2013 Share Posted December 25, 2013 Because the laptop got through POST, the memory was properly recognized in BIOS, and the boot to Windows process began I suspect the memory is OK for the laptop. You may want to try booting using the F8 key and use one of the diagnostic boot options (I am not sure which one to use). You may ultimately have to reinstall Windows.

peanutz94 Posted December 25, 2013 Share Posted December 25, 2013 There should be no reason to have too reinsrtall windows because of a memory swap. besides the OP stated everything was fine when adding the old memory back to the system which are 256MB IC's This system is limited based on CPU.The BIOS recognizing them doesn't mean a whole lot in this case. Actually only Core I7 Quad channel series CPU's will support 64 Gig Core I5 D/C CPU's are limited to 32 Gig because of the number of slots and Core I3 only support 16 Gig of memory and the modules have to made with IC's no larger than 256 X8 Memory IC's so that would 4.0 Gig double rank modules or 16 Gig total. If the MB you have only has two slots then you would be limited to 8.0 Gig of Ram for Core I3 CPU's http://forum.corsair.com/forums/showthread.php?t=116594 Link to comment Share on other sites More sharing options...
JKeifer Posted December 25, 2013 Share Posted December 25, 2013 I would argue that the CPU is fine with the memory because it's the CPU that executes the code contained in the BIOS. Because, in the OP's case, the CPU runs the BIOS initialization routines, correctly initializes the hardware, and begins Windows start-up I still say that the memory is integrating just fine the laptop.

peanutz94 Posted December 25, 2013 Share Posted December 25, 2013 It is also the CPU that designates memory types and IC size too. I'm sorry this has been proven over and over again here in these forums with the I3 CPU's. The newer I3's may be different, but the first /second gens are limited to memory made with 256mb IC's despite the BIOS seeing them. I can assure you, i have had numerous conversations with Ramguy about this. It's also why i posted the link to his response concerning CPU limitations.

JKeifer Posted December 26, 2013 Share Posted December 26, 2013 I'll defer to the experts here and hope that the OP can get his machine working. Happy New Year to everyone! Link to comment Share on other sites More sharing options...

Thats fine, again, thats why i posted RamGuy's response and the thread that came from. You can't get any more expert than that. Link to comment Share on other sites More sharing options...
taser owl Posted December 31, 2013 Author Share Posted December 31, 2013 Ok, just a further bit of information which has me more perplexed. I have been checking out the direct Toshiba recommendations for memory for this model and the ICs they have on the 4GB module are 512mb. Link to comment Share on other sites More sharing options...
peanutz94 Posted December 31, 2013 Share Posted December 31, 2013 Where did you find that information at? Searching your part number says they are 256IC's http://www.samsung.com/global/business/semiconductor/product/computing-dram/detail?productId=5872&iaId=694 Link to comment Share on other sites More sharing options...
taser owl Posted December 31, 2013 Author Share Posted December 31, 2013 When looking directly through Tosh with my laptop full model number it recommends this http://www.toshiba.co.uk/accessories/laptops/system-options-accessories/memory-expansion/pa3677u-1m4g/ Link to comment Share on other sites More sharing options...
peanutz94 Posted December 31, 2013 Share Posted December 31, 2013 I see what your seeing,however I think at this point I would contact Toshiba and ask them about this. I really believe your being limited by your CPU though. The 512's would work for the I5's and I7's, but the I3's have different limitations.
