Question about HP Compaq Presario V2000 Notebook

1 Answer

Problem with amount of RAM.

I have two 256mb RAM (512mb total) chips in my Presario v2000.
It's says that I have only 384 total when I go into the system info (WinXP Home).
I take out each chip and insert them back in, one at a time.
When I put one in, it's says I have 224mb. The other says 224mb.
So maybe I have a bad slot? I put one in the other slot, it still says 224mb.
Only reason I noticed now is because I bought more RAM (512mb chip).
I inserted the 512mb and one 256mb chip, it's says I have 640mb now.

Anyone know why? Do I really only have 640 or is it really 768? (Maybe it's just not displaying it correctly?)
It's not the RAM or the slots, it seems to be only when BOTH slots are occupied.
Please help. Thanks!

    How can I find out if it does?

  • ZexM19 Apr 14, 2008

    You were right.
    The laptop uses ATI Radeon Express 200M video card.
    It uses HyperMemory to allocate up to 128 mb more ram by taking it from the system memory.

    That's why my system RAM shows 128 mb less.

    Thanks!

Maybe your video card uses 128mb shared memory so 128 for video plus 640 reading equals 768.

I have a Tecra 8200 bought as used fitted with 256MB of ram. If I buy an extra 256MB which brings the total to the maximum allowed of 512MB is it likely that I will need to upgrade the bios to allow the...


This laptop came with 128mb ram, you can safely install 2 sticks of 256mb for a maximum of 512mb with no bios update.
You need pc100 sodimms.
Amazon or ebay will be the best bet as this memory is expensive now from a retailer.
I found 256mb sticks for under $10 buy it now on ebay http://cgi.ebay.co.uk/256MB-SODIMM-PC100-SDRAM-256-MB-PC-100-LAPTOP-144-Pin-/190411543153?cmd=ViewItem&pt=LH_DefaultDomain_0&hash=item2c55699271

Adding memory to a a75-s211


How much memory did it have before you removed the 256Mb RAM?
If it had 756Mb RAM then the memory in the laptop has 512 Mb plus 256 Mb RAM modules, the 256Mb in the slot you can see and possibly 512Mb in a slot under the keyboard or soldered on the motherboard.
Therefore by removing the 256Mb and replacing with 1Gb memory module will give you a total of 1.5Gb

Sharp Actius AV18 does not recognize added 512MB PC2700 RAM. The machine still only sees 256MB. Is there something else I need to do?


I assume the laptop had originally 256Mb RAM and you put 512Mb RAM in a the spare memory slot and you expected to see 768Mb of memory, is this correct? Try removing the 256Mb memory module and insert the 512Mb memory module and see if the laptop boots up with 512Mb of RAM. If it doesn't boot up then the RAM is either incompatible or faulty. Try using RAM modules from the same manufacturer.

The memory I install to Armada wont boot


You CAN NOT mix 100 and 133 chips! It is not good for the computer. They may let the computer work, but it won't recognize them properly.
If you still want to use the new chips, try and bypass the acklowledgment. Don't know if it is possible, but it may be the only way.
You should be using the correct chips.

You can go to: 4allmemory.com or cruicial.com to find out what sizes your computer is allowed.

IBM ThinkPad T40 2GB Max RAM


The T40 has two ram slots, you can put a 1g chip in each totaling 2g. If the chip will remove, then it is changeable. Vista needs a minimum of 256 to run, so, when you change BOTH chips to equal 2g it will probably read 1.744g, or it may read the full 2g. If it only reads 1g, then the second slot under keyboard may have malfunctioned. It could also be that the 256 chip is bad and your really only running 512 now. With all that said, in order to achieve 2g, you will need to put a 1g chip in each slot.
