Can I use a Slot A in a Slot 1 or a Slot 1 in a Slot A?

no. one is for amd processors and one is for Intel processors. different technology

yes they are interchangeable.. its more or less a speed rating. unless you overclock, or are going for dual channel, no problem.

no, they are interchangable with any of the same type motherboard

Are there supposed to be multiple choices?

Makes no difference.\n\nThe only thing it affects is the price as 2*1gb would cost more.

dont use ur old stuff unless its ddr2 ... if its older than 6 months it isnt ... dont mix the types or you'll slow everything down , just add another 512 if you have a SINGLE stick, and check out the site the guy above mentioned to get the same speed memory ... if you have two sticks of mem now they are 256 each and most likely in dual channel configuration ... in that case i would get the same speed memory but buy (2) 512s' or (2)1gig sticks ... if you break up a pair of sticks in dual channel or add a third you will slow things down also ...

Should be OK as long as the new RAM is of the same type as the 512.....meaning if your 512 RAM is unbuffered, you need same unbuffered 1gig...or if it is Registered then the 1 gig has to be Registered also. You can't mix different types or the computer won't boot.

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.

look at a few examples and it will make sense\n\nfor example \n\n02 (where the 2 is small)   -> _ O    (the _ is where a number goes)  (2)

Well the second guy is half right, you can of course install them in different sizes.  However to call the performance gain "amazing" is a bit of a stretch.  Plus, you would be forfeiting dual channel mode if you install in different sizes, which is a bad thing.  My suggestion is to save up until you can afford the full upgrade to 2GB.

doesnt matter end color, just make sure the little tab on top of each end fits in the slot

~~only one card will fit in a slot, but you could install another slot onto your motherboard~~

use one of the empty slots in the case to add a wireless card. x

not necssary , but u have to add multiple capacities , means , another 1 GB , or 512*3 , u cant add 256 to 1 GB

NO! Infact, I doubt that you would find anymore PCI graphics cards in stores like Best Buy or Circuit City.  A very breif list of graphics card slots in order of appearance:\n\n1.PCI graphics slot (Phased out)\n2.AGP graphics slot, 4x to 16x (Phasing out)\n3.PCI-Express graphics slot (Recently introduced)\n\nAlso, each slot has a different design.  So you can't place a card for one type of slot in a different type.  It won't fit, making it physicaly impossible without cutting and grinding (damaging the card beyond repair)

No they use different slots.  Laptop memory is physically smaller.
