Question about HP Pavilion dv6000z Notebook

1 Answer

Hp Pavillion laptop freezes when I install secondary memory

I purchased 512 addit'l memory for the laptop and installed it in the slot on the bottom of the laptop. After that it would not boot, get to the post screen and stop, and ocasoinaly it would boot but freeze after about 3 minutes. If I boot to Diagnostic CD it would freeze but take a longer time to do so.

Removed the chip and left it out. booted and ran fine. Replaced origional 256 chip and sill freezes. Ran memory test and all passed. Memory is correct for the systemas well.

Finally I put the new 512 stick in the primary slot under the key board and it runs well. Again, I put one of the origional 256 in the secondary slot, again it started to freeze. switched chips with the other 256 chip and same result.

There are no Bios settings that can be changed; this board has a basic bios setup. cannot see it being a heat issue because it hapens when the systen first starts i the morning and when it is warmed up.

Ive done as much research on this problem but still fail to find any solutions.

    That has been my experience as well, but I get the same freezes in the system when I put the two origional 256 sticks back in the machine in their respective slots. It is almost as if the seconday slot that is on the bottom of the machine is causing problems that previously weren't there. Coud over heating of the system perminatly effect this slot , yet allow the computer to still function fully on the primary memory?

    laptop only has two slots.. so putting three chips at once is not a issue. The TWO ORIGINAL 256 chips were placed in the slots and I encountered the problem with the freezes. There have been numerous posts on the web about this problem from other people with no solution.

    I have for time being placed the 512 in the primary slot and all is well but I tested a 1gig chip and it will not run on this laptop even though HP says it will take a total of 2 gigs of RAM.

    Still hoping for another answer. By the way, about how much would it cost to check a Motherboard ?

    My HP pavilion zv5000 had 256MB cards in both primary and secondary memory slots (total of 512MB RAM). Bought 2 Kingston 1GB cards as replacements to upgrade to 2GB, which HP says is capacity of this laptop. Both Kingston cards are compatible with this model according to HP. With both cards installed (primary under keyboard and secondary on bottom of machine), system either refuses to boot or freezes at desktop. Can get to desktop in Safe Mode. System configuration shows that 2GB of memory are recognized. When secondary 1GB card was replaced with original 256MB card, computer works fine (system config shows 1.2GB of RAM). I am typing this on the machine now. I assumed the Kingston card in the secondary was defective, so I returned that card and am awaiting a replacement. Obviously, there is nothing wrong with the secondary slot, as the 256MB card works fine.

You may not put all together the 256 and 512, the system encountered error when two memory are not equal size and not equal brand.

Either you select 2 units 256 memory or either 2 units 512. or use only 1 unit 512 memory so that no freezes will happen.

    Ok you should install only one memory in the primary slot . Only install 1 512 in the primary, coz maybe the other slot is have damage. you have option on that except replacing the Mboard of the system. but if the primary slot working on 1 512 so why not use it for the mean time.

    That is the problem when the laprop motherboard in trouble coz it hard to find a replacement on it. That is why costing on the laptop check mainboard error i could not calculate.

I installed a 1gb memory upgrade in addition to the 512 that was already there. The computer wouldn't re boot. I removed the upgrade and tride a reboot and it rebooted fine. What's going on?

This may due to the additional memory module is faulty or speed of the memory mismatch. Try to remove the old 512 stick and insert new memory and check. If your system boots, then there will be a mismatch in speed else memory module is faulty.

Thank you for using Fixya.

RAM error

Populating the memory according to the following guidelines resolves this POST error:
  • DIMMs must be configured in identical pairs.
  • The system will not boot properly if multiple DIMMs of varying density or type are installed in the system.
  • The Entry model servers come with a single 512 MB DIMM. If additional DIMMs are to be added to the existing 512MB DIMM, then another 512 MB DIMM has to be added along with the new pair of DIMMs, or it has to be removed when adding the next pair.
  • Valid DIMM pair combinations use slots 1/5 (Bank A), slots 2/6 (Bank B), slots 3/7 (Bank C), and slots 4/8 (Bank D).
  • Up to 16 GB of memory are supported on the Dual-Core 5000, and 5100 series
  • Up to 32 GB of memory are supported on the Dual-Core 5200 series, Quad-Core 5300, and 5400 series
  • FBDIMMs must be installed in pairs unless operating in single-FBDIMM mode. The server supports single-FBDIMM mode only in FBDIMM slot 1A. FBDIMMs must be installed in sequential order, beginning with bank A.

Below are the specs to the type of memory that can be installed in the is very specific and cannot be anything else then what is listed. You have 512 mb built onto the motherboard, with one expansion slot. That slot can only hold up to 1 gb stick if the BIOS has been upgraded. Go to Toshiba support and make sure the BIOS on the machine is up to date so it will accept the larger stick of ram memory and make sure all the specs are right on the stick that you have.

Each memory slot can hold DDR PC2700 with a maximum of 1GB per slot.*

  • Maximum Memory: 1536MB
  • Slots: 1 (1 bank of 1)
  • Standard Memory: 512, 768, or 1024MB (512MB non-removable)
  • USB Support: 2.x Compliant

    How to fit memory to laptop compaq armada e500

    most hp/compaq laptops will have memory slots located under the keyboard, and sometimes an additional memory slot accessed through a panel on the bottom of the notebook.
    In your case, you have 2 memory slots located under the keyboard. Officially, this unit only supports up to 256 mb memory modules for a maximum of 512 MB of memory so if you already have that, be aware that larger capacity memory modules may not work.

    The memory I install to Armada wont boot

    Check the specs of the computer. The model you has two memory slots. One on the bottom of the notebook. One under the keyboard. Each equal 64 mb thus 128 mb. You need to replace both with sdram 256 mb sticks not one 512.
