Can 2 different types of RAM be used together (on the same Motherboard)? Both are DDR Ram, but different DIMMs

The straight forward answer is you may be able to use two different sizes of DIMMs (256MB, 512MB or 1GB), but you can't mix different types or speeds of DIMMS (such as 266MHz, 333MHz, or DDR-2100, DDR-2700, etc.).  You will need to always match the memory type or speed in "MHz" for them to work.\n\nSome motherboards require you to install two identical RAM modules at a time.  The best thing to do is ask a RAM distributor online such as www.buymemory.com.  They will tell you exactly what RAM type you need and can save you quite a bit on memory versus any retail store.

go to www.crucial.com\nthere you will be able to find out your memory type\nmost probably a small software will be downloaded\nthe execution of that small software could result in telling you the type of RAM your system can accept\nok

No you cannot. RAM sticks inside the PC are 'lightning fast' compared to USB sticks. USB are horribly slow.\nAlso, RAM memory is made so that it forgets everything when the power is taken away. USB sticks are the opposite. They are 2 completely different types of memory.

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

The RAM modules' speed must at least match the memory controller on the motherboard. You can always use faster RAM modules than required, but not slower.

There is absolutely nothing to worry about installing the RAM on your own. \nYou have to keep certain things in mind. \nThe first one being, you have to find the most suitable ram for your motherboard. The memory specifications for your mother board would've come with its manual. \nMotherboards have a limit of how much ram it can take. So verify that before you install RAM.\nThen, balance the load on the dimms. like 2x of 256MB sticks to make 512. OR only 1 stick of 512. Although it really does not matter to balance, its just a good practice. \n\nVisit this link for further details. \nhttp://www.ehow.com/how_895_install-ram.html

you can put two 512mb ddr-266 dimms for a total of 1 gb pc2100 memory

This depends on your motherboard.  Most mainboards targetted at the enthusiast and overclocking crowd support mixed speeds/sizes.\n\nIf you have a motherboard that supports dual channel DDR, you will have to use a matched pair.  Mixing might work but likely you will get really weird results.  Dual channel DDR systems typically have four dimm slots, one set blue and the other black.  You have to populate either both black or both blue (or all) memory modules for dual channel DDR to work.  Each of the colors represents one 'bank' of memory.  When all the slots are populated some boards support memory interleaving which increases performance.\n\nYou typically can have different size ram in two different banks.  So one bank could be filled with two 256MB PC4200 and the other two with 1GB PC4200 (this is the exact configuration I have in my computer) or any other combination, as long as the speeds and sizes match in the same bank.\n\nEven if your motherboard supports mixing ram types, you really should try to get the same speed ram, or faster ram than you already have.  Ram rated at 4200 will have no problem running at 2700.  That will happen if you stick a 2700 dimm in, because all the ram has to run at the speed of the slowest module.

It'll take a lotta time to describe the whole process, so i've listed a couple of links here. Visit those links n read 'em.\nhttp://www.pcworld.com/howto/article/0,aid,18024,00.asp\nhttp://www.ehow.com/how_895_install-ram.html\nhttp://www.pcmech.com/show/memory/87/

If you have an empty slot them you can add another stick of RAM.  Make sure it's the same kind.  You can easily trade out your old CDROM for a CDROM/RW.  Just pull the old one out and replace it with the new one.  You can pick up PC parts really cheap from eBay.

Yes, these two memories have nothing to do with each other.  The DDR2 memory is controled by the motherboard and used by the OS. The memory on your vid card is controlled by the card.

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.

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).

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.

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

You usaully cannot just take memory out of another computer and put it in yours. If it is compatible it would work. I suggest finding out what  kind of memory your system takes first. Check this http://www.crucial.com\n\n\n\nEDIT: by kind i mean PC2700 or whatever, and then go from there. And ram chips are not universel. It has to be compatible with the motherboard.\n\nIt is highly unlikely that it will work.

No, the motherboard can only handle 1 type of RAM.  Look up your motherboard model number to see how much and what type of RAM it takes.
