    Advice on RAM size for Gigabyte motherboard


    Deciding whether to get new PC or put new hard drive in my PC - posted previously on problems- hard drive has crashed.
    The guy who came to help me said to get more RAM - new hard drives and he would repair windows
    Went to purchase RAM and showed the man my manual for my Gigabyte Ultra Durable TM3 MB GA-P55 -UD3P
    Under Memory it says - 4 x 1.5DDR3 DIMM sockets supporting up to 16GB of system memory
    This guy said - it will not take anymore than the 4gb of RAM that I already have installed - I could put more in but it would be not be available?
    I found his accent difficult to understand.

    I do not understand this if it says 16gb why can I not have 16gb?
    I am basing my decision on whether to get a new PC on this as if I cannot increase to more than 4gb of RAM then its maybe time to update.
    Very confused. Thanks for advising me.

    From Crucial site: http://www.crucial.com/usa/en/compat...e/ga-p55a-ud3p

    Looks like 16GB capable, have to expand the tab on the memory list. Can run the Scan Your System button also: Crucial.com - Crucial System Scanner

    PS: Do you have 32 or 64 bit Windows installed? Memory is limited on 32 bit systems. Memory Limits for Windows and Windows Server Releases (Windows)

    Thank you for your reply - I presume you mean expand the tab on the memory on the PC - cannot do - C drive is corrupt- Is there a difference between the amount of RAM that you can install and what is available - I know I have seen on my system info 4gb of RAM 3.5 available. This guy yesterday was saying - yes you can put it in but only 4gb will be available. Makes no sense to this grey haired old lady who is struggling to make a decision.

    I edited my post above. Do you have 32 or 64 bit Windows installed?

    sorry its 32 bit - this guy yesterday was saying well if you update it will be 64 bit therefore the Windows 8 disc purchased 12 months ago will be no good and have to buy 64 bit one.

    I have Windows 8.1 Pro 32 bit - don't understand the x86 but I have seen that so presume this guy is actually correct....its 4gb.....SO my repair guy said for windows 8 i need more than 4gb ram and this guy said similar yesterday but he also thought I could put new hard drives in and keep it. Think I am leaning towards a new PC ....i have i5 and I don't really understand - do I keep to an i5 - or is there something better - on the price list he gave me it goes up to Intel Quad Core Zeon - but he highlighted the i5 but presume the processor speed is a lot faster than what I have.

    I can't help but think the guy is trying to sell you something you don't need. The i5 is a good processor and you can install 64 bit from the same disc you have.

    You don't need more than 4GB of memory on 8 depending what you are doing.

    Can you post the exact make/model of your computer?

    Sure have model number of motherboard correct, Gigabytes site does not show model you list GA-P55 -UD3P
    Shows GA-P55-UD4P GIGABYTE - Motherboard - Socket 1156 - GA-P55-UD4P (rev. 1.0)
    And GA-P55-UD3L GIGABYTE - Motherboard - Socket 1156 - GA-P55-UD3L (rev. 2.3)

    Both capable of 4x4GB DDR3 1.5V RAM would be 16GB that is max on these boards above, all 4 slots being filled, either fill 2 slots or all 4.

    As Popeye said, give make and model of PC,help more

    before i turned the PC off completely as cannot access C Drive I managed to print the system info from Accessories system information - cannot access Device Manager or anything like that.
    Firstly - it was the PC repair guy who said I needed more than 4gb of ram for Windows 8 - and he was of the opinion that I could add to it.
    The guy yesterday was also encouraging me to keep my system but said I could NOT add to the ram. He is happy to install my drives and load windows 8 for me.
    So this is what I printed out.

    System Model PFF-UD3R
    X86-based PC
    Intel(R) Core TM i5 CPU 750 @ 2.67 GHz, 2793 Mhz 4 Core (s) 4 Logical Prcessors
    Memory 4g
    Total physical memory 3.50 gb
    Available memory 2.28 gb
    Total Virtual Memory 7.00gb
    available virtual memory 5.15gb
    Is there anything else you need - not sure if this is what you require..
