Memory When purchasing memory, can someone tell me what is meant by PC 2100, PC 2700? On my memory stick I can see a PC2700, so does this mean I have to stick to a PC2700 memory stick?

    The number is the speed of your RAM Manufacturer and model # of your motherboard will help me decide if you can go with faster memory.

To answer your first question, yes, anytime you buy memory it has to match..it must be PC2700.

what that means is the throughput speed of data your machine can handle. It has to do with the memory type, the speed the data travels, and the clock speed. Every motherboard has a clock that pumps data at a certain rate.
So let's say your clock speed is 167MHz. You have DDR RAM which means Double Data Rate. DDR sends data on the up cycle of the clock and the down cycle of the clock. So you are really sending data at (2 x 167) 333MHz. Now data travels in 8 byte chunks. So you multiply 8 x 333 = 2.6666 or 2700MBps-Mega Bytes Per Second or 2.7GBps. So voila PC2700 RAM stick. So that is why you have to always by the same RAM so it will match your clock speed. Well you asked :)...

I want to upgrade my processor and memory on my acer travelmate 4000. I currently have an Intel Pentium M 1.5GHz 496RAM processor. I have 2 memory slots each containing 256MB type DDR PC2700, DDR...


I suggest adding 2X 1GB DDR PC2700 memory sticks. Crucial also recommends it, but as long as it's only 1gb thats DDR PC2700 per stick it's compatible, so you can shop around if you like and choose the cheapest.

Hope this helps!

I have an emachine T5026. Emachine tech swears this machine only supports pc2700 ram but the stickers on the factory installed ram says pc3200 256mb x 2 so i bought 2 memory masters pc3200 1gb x 2 sticks....


PC3200 is backwards compatible with PC2700. Meaning you can install PC3200 into your motherboard but it won't run any faster than would PC2700, however it will not cause any harm and should work fine.

Emachine's would say you need PC2700 most likely because they're trying to sell you some.

One of your new memory modules or the memory slots on your computer may be defective. I recommend installing a single stick of memory and booting your system. If it is successful then shut it down, disconnect the power and install another stick. Boot again and keep doing so and by process of elimination identify the bad memory stick or the bad memory slot.

This is the "likely" cause and isn't too uncommon.

Good luck.

Hello.

Memory is not interchangeable. Depends on your system, as to what memory to use. An error is telling you the memory is not correct for that PC.

Your Dell Optiplex sx 270 uses DDR PC2700 and DDR PC3200 memory.

Hope this helps.

RAM compatibilty


No, DDR 400 will not work. The best thing you can do is call Dell and give them your information. Model number and that kind of information and let them tell you what kind of ram you need. If you put the wrong type of ram in your machine it could cause major damage. There are so many different kinds of memory out there, not to mention high and low denisity. Your machine may use PC2700 high density and if you try to use PC2700 low density it will not work. One other thing that you can try is uninstall a stick of your ram and write down everything on the stickers and then go to some place like kingston memory and use their memory locator to find what you need.

make sure they are compatible with your computer, there are alot of electronic stores (circuit city) was the worst at it, but will sell you the wrong ones and say they are backwards compatible.. usually P4 2.8 can run PC2700, some run PC2100, which im hoping yours is PC2700... if so, make sure they are NON-ECC also... i would just get 2 1 gig PC2700 DDR 200pin sticks and stick em in... good luck

What is the maximum memory for this computer?


This computer (HP Pavilion a620n) has 2 x 184-pin DDR DIMM sockets and supports up to a maximum 2 GB of memory. It supports unbuffered PC2700/2100 non-ECC DDR SDRAM memory. (Also known as DDR333 and DDR2100 respectively)

Can you expand the memory on a Systemax Intel SIS651 System


Your motherboard is actually a Foxconn 651M03.

According to your system you have :
512MB DDR333 PC2700 Non-ECC Memory (512MB x 1)
(One stick of 512MB)

The motherboard manual says this:
System Memory
Two 184-pin DDR DIMM slots
Supports PC1600/PC2100/PC2700 memory
Supports 64Mb/128Mb/256Mb/512Mb technology up to 2GB

(This means you can have a total of up to 2 Gigabytes of RAM)

If you upgrade your RAM, you will need to make sure that you get the correct type.

If you want to keep the RAM you have, you will only be able to have 1.5 GB of RAM because you only have two slots to work with. If you want to upgrade to the full 2 GB, you will need to buy 2, 1 GB sticks.

Was your 1gb stick DDR PC2700? Most likely that is why. Although the pin set are both 184 pin, you will be downgraded to the lowest speed available, meaning PC3200 (DDR400) will downgrade to PC2700 (because PC2700 can't be upgraded to PC3200).
