does it matter if i have two ram chips pc3200 and two ram chips pc2700 in a bank of four?

agree with previous post but I dont think mixing and matching ram is such a good idea, your probably better off seeing what your motherboard supports and sticking with one type and make of ram.

Not unless you're gonna be overclocking your computer.\nBut if you're not, get memory with the same specs (at least): DDR2 PC2-3200. Before you do, check to see if you can add memory. If you can add memory, buy memory of the same brand and model (other brands/models are likely to have different timings, causing all sorts of problems).

go to http://www.crucial.com and download their tool for seeing what kind of RAM you have and what is their recommendation

As long as the MotherBoards for those two machinces are the same it should work fine.

Couple possible reasons:\n\n1. Your PC uses RDRAM (which, chances are, if you don't do it right, it won't work at all, but you might get this crazy response that you report). RDRAM is a special expensive RAM that *needs* to be in pairs... cannot have unequal pairs. \n\n2. RAM chip is either inserted incorrectly, or has malfunctioned. There is nothing wrong with part of the chip, but the rest has failed. \n\n3. Some kind of software (most like firmware driven by motherboard) is limited the amount. I doubt this, but it's possible. \n\n\nPrognosis: What are you using to test the amount? Download a program called CPU-Z and it will give you ALL the information about your pc, including the RAM chips and what is being reported back to the computer. You might be able to troubleshoot it through there. Get it here:\n\nhttp://www.cpuid.com/\n\nPS... Shortcircuit computer has a good idea also.

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 ...

Your new RAM must be DDR2...Besides, nothing else will fit as DDR2 has 240 pins, DDR has 184 pins and older SDRAM has 168 pins (for desktops anyway...laptops have a different number of pins than desktops, but each type still carries a separate number of pins from the other types).  Use the recommended speed as Dell computers are built only to handle a certain speed and, generally, are not upgradeable much less downgradeable.  Using memory of a different speed can cause your computer not to boot up and could possibly cause damage to the memory and/or motherboard.  Placing them in pairs is not absolutely necessary nor is using identical memory size chips, however, if you do use 2 sticks of identical memory, it gives the added benefit of using Dual-Channel which significantly enhances the performance of your memory and processor and, thus, your whole system.

U can put the ram in as long as it has room for it. Normally computers have 2 slots. Just make sure that u have and empty slot and the new RAM is on the same frequency. Not having the same frequency will lead to a lot of system crashes. \nThere should be no trouble in putting the new one in, u will have a better performance no doubt.

Agreed..... check out the crucial web site and find out exactly what kind of RAM your computer will support.  But even if it says you can use the two sticks you already have, you could have some other compatibility issues.\n\nThe 512MB may be 333MHz instead of 266Mhz like the 256 stick.  Even if you could run them together, the different frequencies could be a problem.  Your computer might run at the slower frequency (if, in fact, the 512 has a different frequency, is  it also backwards compatibile.  Meaning, will it actually work at a slower frequency.)\n\nThe second issue is whether or not your computer will accept two different RAMs or do they have to be the same (in pairs.)  If the computer will accept different RAMs, make sure to check if they need to be installed in any particular order.  Some computers require that the largest stick be placed in slot # 1, the next largest in slot # 2, etc.\n\nAnd finally,find out if your new computer's warranty will remain in effect if you choose to deviate from the manufacturer's specs.  Nothing worse than spending big bucks on a computer, violating specs, needing repairs, and spending more on the repairs than you did on the whole computer because you trashed your warranty trying to save a few bucks.

OK, this is the actual procedure, read carefully.\n\nIf you have already bought the RAM, skip this paragraph and go to the next step. If you have not bought it yet, just remove your old one and take it to the shop. Tell them you want the same type of RAM but in a different/same capacity. This saves you alot of trouble telling them whether it's SDRAM or DDR RAM. Just bring the sample.\n\nThere is no installation involved. You just need to put the new or additional RAM into the DIMM slot(there is only one type of slot for RAM so you can't go wrong) and start your computer, that's all. The computer will automatically calculate the new size of the RAM and adjust itself automatically.\n\nIf you are still unclear, do not hesitate to post here. Good luck!\n\nCheers!\nALWAYS LOOK ON THE BRIGHT SIDE OF LIFE

You would have to first learn whether or not your motherboard supports the faster RAM.  http://www.crucial.com has a great tool to help you figure it out.

You can, but you are limiting the performance.  Make sure they are both the same type and they work in the same frequency(PC2700, PC3200 etc)\n\nBattery Wizard

no i dont suggest you to use both the rams bcz 512 ram is 33mhz and 124 ram is 133mhz the data transfer rate is different in both the rams.  your system will be hanged frequently so. dont use both.

The difference is one will not fit in the other. You need to find out what your motherboard takes and that is what you want to get. If you own a Dell or a store bought computer like that then their web page should get you straght as to what to get. Yes it does matter what you put in the damn slot and can mean improving your computers speed or slowing it down, even if you are adding more RAM. Just a little note, 2 gigs of Ram is a good idea espically if you plan to upgrade to Vista after it is released.

If you still have the owner's manual, look it up there.  If not, go to the website of the manufacturer and find your model and look up the specs there.\n\nThe mainboard will require ram that has a specific bus speed [e.g., DDR 333 aka PC 2700], a specific type [ single data rate or double data rate], and will support a certain amount in mb's [1 gig, 2 gigs].\n\nYou can usually find what mainboard you have by going to Start, All Prog, Accessories, System Tools, System Information.  With System Information highlighted on the left pane, on the right under System Manufacturuer and System Model your mainboard will be listed.

pc700 memory modules are not supported by this mobo (850 chip set) and may run at pc600 speed.\nto run dual channel mode, both ram modules have to be of the same size and speed. therefore a 128mb and a 512mb (btw with different speeds) will not work properly.\ntry to run both modules in bank 0 or remove the 128mb module and put the 512mb in bank 0.\n\nhere is the description from Intel\nhttp://www.intel.com/support/motherboards/desktop/sb/cs-009040.htm

Yes you can.. I have 512 and 1024 in mine - as long as the memory is the same type and if they are different speeds - your PC will run both at the slowest of the two's speed as long as they have SPD (Serial Presence Detect) which autoconfigures your SODIMMs.
