RAM memory in a Presario computer

My Presario HP computer can take up to 2 gigs of ram.  Do I have to have equivilent ram chips in each slot or can they be uneven?

    Thanks, but here's the next problem. I already had 250 mb of ram in the computer and I installed a 1 gig chip. But the readout on the computer says I now have 865 mb of ram installed. What gives?

  • bill664 Nov 15, 2008

    I'm using the memory calculator built into the computer. In the control panel there is a line that says, "Show how much Ram is on this computer?" When I click it, it shows 895 mb. I must admit, after installing the new RAM the computer is about ten times faster. I'm basically a MAC person so this PC stuff is really foreign. MACS are so straight forward. Thanks for your help, whomever you are.

    are you usuing the on-board graphics?

  • Lee Hodgson
    Lee Hodgson Nov 15, 2008

    it sounds to me like the system is sharing memory for the graphics, there is an option in the bios where you can limit the amount of shared memory, from what you say its using 512 of system memory all you need is 256 that should boost the pc's performance

Hello,

No, it does not matter what size ram modules you have installed, aslong as they are supported by the laptop.

You can have 128MB on one slot and 1024MB on another for example, but these days its more common to have sizes like 1024MB and 2048MB. As long as the size and speed, type is supported it will work.

Thank you,
I will fix it!!

  • Sorry what memory calculator are you using? that doesn't sound like a valid amount of memory look at the size of memory the computer setup - bios showsn to get into bios you need to press the a button, the computer will notify you when you power up what button to press to enter the bios.

  • Ok, its most likely that the missing amount of memory is shared, and is being used by your video card.





    Can you rate my solution by the way?



    Thanks!

Can a compaq presario f700 handle one 2 gb ram chip


Simply put, no. It can handle 2 gigs TOTAL but not a single 2 gig chip in one slot.

INSTALLED NEW RAM UPGRADE TO BOOST FROM 1G TO 2G COMPUTER DOES NOT RECOGNIZE NEW RAM STILL SHOWS 1G.


Make sure it is the correct ram for your computer. If you just added one ram chip then try swapping them and make sure they have a tight fit.

To test the new chip replace the old one with it and turn on your machine. If it doesn't see it then it is either bad or not the correct one.

Let me know how it goes.

DDR2's only showing half installed RAM


IF THE SYSTEM SAYS YOU HAVE 1GB RAM THAN YOU HAVE 1 GIG OF RAM, EVEN THOU SOMEONE TOLD YOU YOU HAD 2-512MG=1GB.

HERE IS HOW I SEE WHAT YOU ARE SAYING YOU HAVE 2-DDR-2 1 GIG STICKS THAT MEAN IF 1 IS INSTALLED THAN YOU HAVE 1 GB AND IF YOU COULD GET 2 STICKS WORKING TOGETHER THAN YOU WOULD HAVE 2GB RAM.
1 CHIP SET = 1GB RAM
2 CHIP SET = 2GB RAM

YOU MOTHERBOARD MAY NOT ALLOW THAT MUCH RAM, OR WHAT I MEAN THE BIOS MAKE UP THE AMOUNT OF RAM.

TO RULE OUT ANY BAD CHIP SETS OR GOOD RAM OR BAD RAM.

TAKE THE PEACE OF RAM THAT IS WORKING OUT AND REPLACE IT WITH THE OTHER PEACE AND SEE IF IT WILL RUN.
IF IT WORKS THAN LEAVE THAT ONE IN PLACE AND INSTALL THE SECOND PEACE IN THE SECOND SLOT.
IF BOTH CHIP SET ARE GOOD THAN BOTH SHOULD WORK OKAY TOGETHER.
IF THERE IS A PROBLEM, IT MAYBE SOME DUST IN THE MEMORY LOTS
OR THE SLOT MAYBE DAMAGED.
OR
THE CHIP DESIGN LAYOUT MAYBE THE OPPOSITE SIDE, THIS MAY MEANS THE CHIPS MAY FACE EACH OTHER, OR FACE OUTWARD FROM EACH OTHER.

Is my presario v5000 using my ram upgrade


where did the ram come from? did you buy it or pull it from another computer? its possible the chip is either defective or not for your computer depending on where you got it, its also not that much of an increase so you may not notice it i would suggest getting another 1g stick because yours should take 2g 1 in each slot.

Upgrade ram


Each memory slot can hold DDR PC2700 with a maximum of 512MB per slot. 2 slots=1 gig or 1024MB ram.

Reg ram upgradation


Each memory slot on the C555NR can support a maximum of 1GB of RAM. There are actually 2 slots, but only one is easily accessible to you. By upgrading both the primary and secondary DIMMs, you could achieve a total of 2GB of memory but you would have to remove the 512mb chip that is already installed and replace it with 1GB (+1GB in the expansion slot as well.)

If you don't plan on taking the computer to a professional to be serviced, you will probably only want to upgrade the memory in the secondary slot located under the memory cover on the underside of the computer. It can handle a 1GB SODIMM.

FYI the memory is:
200 Pin DDR2-533 PC2-4200 SODIMM

Good luck!

Ram memory


Okay, I have a stupid question, the more powerful the chip the hotter it runs. It could be the second slot will not work with a 1 gig because of heat issues and ventilation?

I have the same problem, with 2 one gig chips. I am going to try to replace the easy access slot with a 1/2 gig chip. I'll let you know.

Cheers,
Paul

Install 2 RAM modules of 1 GB


The other memory may be soldered in. Check your manual and see if it has any information on additional memory. If you only have on expansion slot you may have to buy larger memory chips. like instead of 2 chips 1 gig each you may have to purchase a 2 gig chip. Computer companies usually make the chip installation easy to get to on lap tops.
