Upgrade to memory

Does memory upgrade need to be in pairs? Or could I replace just one of the 256M parts with a 1GB part to upgrade to 1.25G?

Re: Upgrade to memory

Depend on the capacity of the mainboard.... you cannot just arbritarily replace mem for higher capacity... the Architecture of the mem has to be taken into account, or the memory you buy may not work properly. and mem which may function in one model may not work in a similar model....for instance mem for the 3000 series may not work in a 3030 or a 3050 so it is best to check.

There is a memory configuration tool here which you can use to find which mem is best suited for your machine. also kingston's mem has a lifetime guarantee

Re: Upgrade to memory

Good afternoon, mikieat!
Yep! That should work. After installing the memory modules, the 3000 should come up and automatically detect and configure your added memory.

I can not upgrade the memory of my laptop, i have buy a new 256M SDR ram and put in the opposite socket and restart, but its BIOS still 256M at the same(it should be 512M). I try more than ten times but...

try to remove all memory and place only the new memory, if things goes right, there is a problem on the compatibility on your new memory, it should have the same speed as your old memory

I have a compaq presario cq60-215dx notebook pc, was wondering how do i go about upgrading the RAM?

I have checked the Compaq Presario CQ60-215DX Specification It Originally has 2GB Memory and supports upto 4GB RAM max. If you intend to upgrade the RAM, you can buy additional RAM and put them in you system. Here is the HP Guide to Replace RAM and How to Upgrade RAM Guide
Compaq Presario CQ60-215DX has two RAM slots for DDR-2 (533 or 667) Memory Modules. First you have to check that the RAM slot is available for additional RAM. I believe that it has two modules of 1GB each in both slots. So, you have to get two modules of RAM 2GB each to upgrade to 4GB (or one 2GB RAM module to upgrade to 3GB). Hence, it is recommended that you get 2GB replacement module for each 1GB module you have on you system from local laptop repair/ service center, which would be cost effective as existing 1GB RAM Modules would be useless for you upon upgrade.

Let me know if any further clarification/ assistance is required.

Good Luck!
Appreciate generously, if the solution could have been of any help!

Can i upgrade my ram?

If you goto and use their memory checker tool you can find out which RAM you need as well as the maximum your motherboard can handle.
Next open your desktop or the section on the base of your laptop where the RAM resides to make sure you have a spare slot and how many slots you have.
It is recommended if installing more than one memory module that you used a matched pair. This is to ensure compatibility. A matched pair is when you buy two of the exact same modules (same spec and manufacturer, model etc.).
Hope this helps,

Compaq Presario Notebook V3000T I replaced the 2-256mb memory cards with 2-1g memory cards. System boots up but only reads 1024mb?

Thanks to Microsoft Knowledge Base for help with my answer:

First, find out what the maximum amount of memory is. This is generally listed by most of the manufacturers. This will let you know what upgrade potential the system has. Next, determine how the memory configuration is when you buy the system. For example, a laptop that has 2GB of memory can be configured as either a single 2GB module or two 1GB modules. The single memory module allows for better upgrade potential because by adding another module you are gaining more memory without sacrificing any current memory. Upgrading the two module situation with a 2GB upgrade would result in the loss of one 1GB module and a memory total of 3GB.

Memory upgrade

We have the memory you need. Memory-Up is committed to provide the best memory and excellent services for all of our customers. We know that sometimes it is a bit confusing to buy the correct type, speed, and capacity of memory for your system. Therefore we hope that these tips below would help you for buying the new memory.
Memory Upgrade Tips

What is Compatibility and Memory Density Issue?

Memory module can be composed using different type of memory chips and therefore created different type of density for the module. For instance, a 512MB PC2700 DDR SODIMM memory can be composed using eight 32x16(High Density 512Mb technology) memory chips or sixteen 32x8(Low Density 256Mb technology) memory chips. As the laptops are equipped with different memory chipsets, some older laptop (chipset) would have compatibility issue working with the modules that is built with the newer 512Mb technology. Using the Not-Compatible memory will result the laptop to either not boot or only recognizing half of the memory modules. Thus that is not the correct memory for your system. Our Memory Finder and Memory Scanner will help to eliminate those problems and find the correct memory for you. We guaranteed the memory to work or your money back. 

How much memory do I need?

Here are some general descriptions for different type of users and the amount of memory they would need for their systems.

Normal User: The system is mainly used for checking e-mails, processing word/excel file, and web surfing. Suggestion: 512MB to 1GB of system memory. 

Power User: The system is mainly used for playing computer games, editing photos/videos, running database queries, or multi-tasking environment. (Surfing web/Processing Word/Excel File/Listening to Music). Suggestion: 1GB to 2GB of system memory.

Super User: The system is mainly used for running large number of database queries, professional editing of photos/videos, heavy multi-tasking environment. Usually a server or a workstation would be considered as Super User due to the multiple accesses from users. Suggestion: 2GB and above of system memory.

How much memory and memory slot do I have with my system? 

You can download our Memory-Scanner to find out the the amount of memory that you have and the memory slots that are available for upgrade. 

How many memory module should I buy?

It is recommended to purchase one module with bigger capacity than two modules with smaller capacity. For instance, if you can buy either one 1GB memory module or two 512MB memory modules for your system, it is recommended to get one 1GB and leave the other memory slot empty for future upgrade if necessary. 

Note: For systems that supports dual channel memory mode, although memory modules need to be installed in pairs to enable Dual Channel Memory Mode, we still recommended users to purchase one bigger module than two smaller modules since Dual Channel Memory Mode has only a minimal improvement in the actual system performance.

What if I want to mix different memory together?

Different sizes/speeds of memory can be used together as long as their specification are qualified by the systems. For instance, a laptop can use one 256MB and one 1GB of memory for the total of 1.25GB system memory. Mixing two different speeds of memory modules would result the system to run at the speed of the slower memory between the two modules. We recommend users to use our Memory Finder or Memory Scanner to find the correct memory for your system.

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!

Compaq presario c714nr upgrade memory too 2gb laptop

Page 43 of this manual seems to have the best documentation on memory for this machine. I saw a 2GB max in another document and this shows the biggest module as 1GB. I would believe that infers a pair.
