What is184-pin DIMM sockets for DDR333/266 memory bus?

To add on the posts above.  Yes you will want to get the faster RAM, especially if your motherboard supports that bus speed.  Even if your motherboard's bus speed is slower, get the faster RAM, it will slow itself down automatically to operate with your system, but if you ever decide to overclock your FSB, then you won't have to worry about frying the RAM modules.\n\nFor reference, 266MHz RAM is referred to as PC2100, and 333MHz is referred to as PC 2700.  PC 3200 is 400MHz and it goes on.  \n\nThere are other factors to the speed of a RAM module that are often overlooked.  Make sure you purchase low-latency RAM.  It will be a bit more expensive, but well worth it.  The cheap RAM is called high-density, then you have low-latency and ultra low-latency (may be others).  Also, make sure you check the SPD timings (Serial Presence Detect), and compare them.  The lower the numbers, the faster the RAM.  Hope this was informative enough.  Good luck.

To test the ram, start by only using one RAM module at a time and test it that way.\nAlso try a program called "MEMTEST"\nhttp://www.memtest86.com/

You need to buy more/bigger dimms for your computer. If you go to the store and tell them you need more ram they should be able to show you what it is. You may want help putting it in so see if they can help you.

http://www.newegg.com   make sure you get the right type of ram

the DIMMS are silicone chips attached to a printed circuit board.\nSoDIMs are the same, just a different shape (generally for laptop use).\nThe only way to tweak your memory speed is by altering the motherboard controls, NOT the RAM chips themselves.\nDIMMS do not have a writeable EPROM.\nYou can buy faster RAM cheaper than you can reengineer existing chips.

Bogus dude has it right.  Use crucial.com to find out how many RAM banks you have.  Then as a suggestion, use their part numbers then go to newegg and order those part numbers from them.  You can buy ram anywhere so...\n\nOn a secondary note, you could try to match your RAM, you mention you are running 128 of pc2100 and 256 of pc2700.  It would be best if you ran the same types of ram in all your banks.  They even have matching ram sets that run at double data rate.  Currently your ram is dumbing itself down to pc2100 speeds.

For now, no, but AMD is hard at working on new processors that support the M2 socket (940 pin) and all the processors that support the M2 socket will support DDR2.  \n\nMost AMD chips have on-die memory controllers and the current lineup of AMD processors only support DDR memory.  It's not a situation as with Intel where you can mix and match chipsets so that the type of memory supported by the chip is independent from the CPU.  With AMD processors (all but the old socket A processors that did not have on-die memory controller) you are stuck with DDR.

There are thoudsands ones. And over 90% mainboard support for DDR (DDR1 as you said), which may also support DDR2.  We have other 2 types are DRam and Ram Bus, but they are "pasted" way.\n\nJust read the information on the wrbsites of these companies, you will know what type of memory they support

You might be better off going to Crucial.com or one of the other good memory sites and letting them test your machine.  They can tell you exactly which configuration will and won't work on your motherboard.  It's possible to save a lot of money by getting an expert's advice on that.

Effectively, no.  PC133 is SDRAM packaged in a DIMM.  (See the Wiki page in the sources if you want more information.)\n\nIf you're intending to upgrade, assertain how much memory you can install in your PC and then ask for whatever number of megabytes of PC133 that you want prior to handing over your pennies.  The vendor will know what you mean.

Some of these answers are wrong and others are not clear enough.\n\nYou need to first check with either the PC maker or motherboard manufacturer and see:\n\n1. What is the total amount of memory supported by the board?\n2. Does this memory have to be installed in pairs?\n3. What type of memory am I currenty running so I don't break Double DDR by installing a single DIMM\n\nBasically your usually better off with multiple chips rather than a single large chip. Your cost per MB is usually lower this way plus if the system is designed to use multiple channels you get added bandwidth by splitting the memory into seperate banks on seperate busses.\n\nCrucial has a pretty good web site for finding out what memory your system can take but don't take that for gospel.

go to your manufacturers website, or the website manufacturer of the motherboard, and enter the model number and search for specifications.  It may also be in your manual.  Today's comptrs usually take 4gb RAM.\n\nYeah if u just want to know what u got now do as above.  What I've said is to give u the maximum capacity.

Here is the link for the Dim 3000\n\nhttp://support.dell.com/support/edocs/systems/dim3000/en/SM/parts.htm#wp1055121

if ur machine is limited to 2100 then it should work but will run at 2100 speeds unless you overclock .... i wouldnt mix up the ram though ... if ur getting a gig of 2700 try it by itself without the old stuff in ... if its not stable u may need to bump the ram volts a  .1 or so up if ur bios allows it ...
