Question about HP Pavilion a305w (DM181AR) PC Desktop

2 Answers

Installed a new memory now computer won't boot up.

I recently purchased a new Kingston 512MB Ram DDR and once I installed it my computer wouldn't boot up until I removed the 256MB that came with the computer. Can I use both and how can I solve this issue? I have a HP A305W. The new Ram is supposed to be compatible for pc3200, pc2700 and pc2100 well that's what the pack says!!! Can I put my 256 back in with this and how do I get my system to run with both of them????

The problem there is you need matching pairs of RAM

Example: 256mb + 256mb
512mb + 512mb

You cannot mix 2 togther.

I have got a compaq presario 6000 series pentium 4 desktop. I bought a 1GB kingston PC2100 DDR ram, 266Mhz ram for upgrade from my earlier 256MB ram. Somehow my desktop doesn't detect the memory upgrade...


the bios might be seeing it but windows might not, the possibility exists that windows is not able to view the full amount of ram installed try this. go to the start menu > accessories > system tools option and look for the system information tool, this will tell you more about the ram installed, note: windows dose on occasion report the wrong amount of ram when their is a 64 bit os installed or their is a 64 bit system

About my ram of p4m800-m7 rev 3.1 i have a 512mb ram already installed and i buy a new ram with a 1gb size and i would like to install it but my question is is it okay to put them together? my 512mb ram is...


The black rectangular chips on the side, or sides, of the ram module are DRAM chips. Dynamic Random Access Memory.

('Chip' is slang term to denote IC, or Integrated Circuit)

Each Dram chip is of a specific size, (or can be said as Amount)
There are manufacturers who make the Dram chips, and then the chips are used by the ram memory manufacturer.

Doesn't matter how the Dram chips are arranged. The ram memory manufacturer could put them all of one side, if they designed it that way.

1.Your motherboard will support, (Use), DDR at 333Mhz, or DDR at 400MegaHertz.
(PC2700 and PC3200, respectively)

2.The ram memory module must use 2.5 Volts.
(JEDEC has set the voltage standard for DDR Sdram at 2.5 Volts, so no worries here. Only time to check this, is if you have some High performance ram, that may be set to use a higher voltage)

3.It must be Non-ECC ram, and Unbuffered.

4.Cas Latency should be 2.5 to 3.0 (Ram Timings)

Short solution?

Computer off, and unplugged from power. TOUCH the metal frame of the computer case to relieve your body of Static.

Handle the ram 'sticks' by the body of the stick, and refrain from touching the gold plated contact pins, on the bottom.

If the 512MB stick is in SLOT 1, remove it. Install the 1GB stick in Slot 1. Make SURE it is seated!

(Slot 1, is the ram memory slot that is closest to the Processor. It is the first ram memory slot that the Processor reads)

Leave the computer case open. (Refrain from putting your hands in while the computer is plugged into power)

Plug the computer into power. Wait 30 seconds. Turn the computer on.

Computer boots up? (Starts)
Okay.
Unplug from power. Install the 512MB stick in Slot 2.
Plug into power, wait 30 seconds. Turn the computer on.
Computer boots up?
You're good to go.

1GB ram memory stick is in Slot 1, and the computer does not boot up?
Incompatible ram memory. Remove it. Reinstall the original 512MB stick in Slot 1.

PC can't boot LEDs are all Amber colour and flashing.


the memory sticks are not connected properly as you are getting the beeps out of the computer when turning on...
if in case the memory cards are connected properly the system should not beep while turning it on so please try to reconnect the memory cards properly & see if you are getting the prompt"the amount of system memory has changed" coming up in that case the system is working fine.

Need to add RAM


Hello,

Located here is the actual specifications of your W3052.

http://www.emachines.com/support/product_support.html?cat=Desktops&subcat=W%20Series&model=W3052

The DDR means "double data rate", SDRAM is "synchronous dynamic random access memory" and DIMM is for "dual inline memory module". These are the way manufacturers describe the specific speed, type, and packaging of the memory. You need to get the correct combination for your computer in order for it to function properly. The PC2100 is NOT correct, at the very least it will slow your computer down, and possibly will not work at all. You should use PC2700.

If you wish to add another 512MB taking your computer to 1GB total, then you only need 1 module, a 512MB, like the one that came in the computer. Do not purchase a 1GB module expecting it to work properly with the one already there. It probably won't. If you want to max out your computer's memory taking it to 2GB, then you will need to purchase 2 each 1GB modules, and remove the existing 512MB module.

When you go to the computer store, you ask for either "one five-hundred-twelve megabyte, PC2700, DDR, SDRAM DIMM memory module" or "two one-gigabyte, PC2700, DDR, SDRAM DIMM memory modules".

The part numbers from, Kingston, one of the major add-on memory makers are shown here:

512MB = KVR333X64C25/512
1GB = KVR333X64C25/1G

Having trouble with memory upgrade for Toshiba laptop


I don't see anything about DDR2 I do see DDR SODIMM.

Kingston ( a company owned by Toshiba) has the specs you need for your pc. Here is the link:

Continual reboot with second memory module


Your memory isn't an exexact match. The 512MB you have in is probablyis Kingston, part # KT3311/512, PC2100/2700, 512MB DDR. You should get Kingston part # KT3311/1G, PC2100/PC2700, 1 GB DDR. You can use another manufacturer but everything must match exactly execpt the size of course. The speed, DDR, everything. Make sure you have the new chip seated correctly and in all the way first. Of course if it doesn't match the specs of your other chip it won't matter. Best thing to do if buying locally is take the first chip with you. If not buying locally, have it with you when you order to make sure it matches.

Gateway sb-4100-b won't recognize new memory


Check the owners manual of your computer for the correct installation of 2 sticks of memory, this can be critical on computers with 2 banks of 2 slots, it will also tell you the maximum ram that will work. If you do not have the manual, go to the manufactures website and then go to the support link, and browse for memory installation. BPCS
