Upgraded to 4gb memory and get blue screen - IBM ThinkCentre A51p PC Desktop

There is no way of doing this. If your pen drive is 4GB, that means it has only 4GB of memory chips in it. The only way to get 8GB is to buy an 8GB drive. Do not buy an upgraded (to 8GB) one, as they are lower memory ones that have had the firmware tinkered with to show 8GB, when the actual memory capacity is far less.

might be that the ram you got was the wrong ram for that laptop.not all ram work in all laptops.

i would take out all ram , then just put in the 4gig
there is 2 slots for ram
if that is the same then windows may have crashed , try getting into safemode by pressing f8 after bios

you can upgrade up to 2GB (DDR2)
Your computer has 1 memory slot you remove the memory and install a new one.
you can use either
2GB 800MHz DDR2 Non-ECC CL6 SO DIMM
or
2GB 667MHz DDR2 Non-ECC CL6 SO DIMM

One major problem with the motherboard is that on Windows 7 64Bit I cannot upgrade to more than 4GB of ram including the Video Memory, I get a blue screen and I havent found any fix yet for it.

Just refer to your laptop manual. If your manual got lost go to the  acer website and find your product and download the manual.http://www.acer.com.ph/ac/en/PH/content/home .

when upgrading your memory you have to consider the following:

the processor: if your processor has 4gb compatibility mem you can upgrade upto 6 to 8gb.

                      take note that you must not exceed to 8gb or else your processor might be damage.

                      get the processor speed: example core 2 i3 processor, 1.0GHZ-the frequency.

the Memory or RAM(random access memory): get ther specification: example is DDR1 or DDR3

                                                                     PC133 or PC 400. Thats all.

Note: your current memory must have the same memory module(example PC400,PC 133)  or else it wont work.if your going to upgrade your current 4gb PC400 you have to add 4gb memory in PC400 module also.                                         

try to see if that memory is supported with your motherboard. The memory has something to do with that problem.

yes it can be upgrade for 4GB for genuine HP memory. because hp exclusively use hp memory. all Hp pcs uses genuine hp memory.

Hi there.
I recommend you get another stick of SODIMM to replace what seems to be the faulty stick.
If you are using XP or Vista X86 (32bit) then the system will only recognize 2.8 - 3GB of memory, only 64bit operating systems recognize the full 4GB.


Good luck ad thanks for using FixYa!!

Depends of your buget, Extra 4 GB DDR2 800 = $35 (total 8GB) I Have 4GB installed now seems fine, but all of this is necessary?
what application do you need to work?
