Can DDR2 PC533 work with DDR2 PC677 at two slot?

It's very likely but it'll be sluggish if it's lower than your motherboards requirements.

Do you mean DDR2 and DDR ?  GDDR2 are specifically for graphics cards.  DDR2 are 240 pins and DDR are 184 pins  so you will not be able to use these.\n\nBattery Wizard

No you cannot. SD ram has 2 notch and while DDR has 1 notch.\nso you cannot put 1 notch ram(DDR) in 2 notch ram slot (SD)

DDR I & DDR II\n\nif u mean maximum in MB / GB , i guess u get 2 GB each\n--- all depends what u'r motherboard is and supports

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.

Probably not. You should make sure that both types of memory are compatible with your PC, next make sure that your motherboard supports using two different types. I have seen some computers that had to have the memory paired with the same speed and type, others require that the larger Mb Ram is put into the first slot and the smaller is put into the second memory slot.\n\nIf you are comfortable with computers and know your way around them a bit you can just install the memory into the slots and see what happens. If when the PC restarts and it gives off a few beeps then there is a memory conflict. If so all you need to do is power off the PC remove the memory and then repower the PC. If it beeps again then you may need to reset the CMOS jumper. Hope this helps

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.

Mostly, u have 2 check the type of ram supported by both computers. Most recent compiters support DDRII RAM Technology which supports DDR one RAMs. But if the old memory is SDRAM, it might not be suppoted by the newer laptop. A DDR one RAM will mostly be supported by new ACERs and DELLs.\n\nNext time, if u need help through such an open community, where no one knows any thing bout ur laptop, better specify the laptop model number, or mention the main features such as the RAM type and size.

Chip 1 ??, chip 2 is 4mb. They both are old, so even if you wanted to use them, they most likely (99.999% sure) wont work in a modern computer.

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.

Yes you can, that is if your mainboard is a newer kind.  I have a 256 mb DDR before and i recently purchased 512mb DDR additional ram for my pc to work well.  \n\nJust install the new ram in the memory slot in your mainboard, make sure that you put it properly to prevent boot-up errors.  When you restart your computer, you will see if it is recognized since there will be more ram in the boot-up details.\n\nIn my case, i even have a DDR 333 256mb ram and the latest one i purchased is 512mb DDR 400 ram.. So far so good it has been working perfectly and i have not encountered problems (like my pc rebooting constantly and such). But i know that my 512mb ram is not performing as DDR400 like it should coz it matches the clock speed 333 of my 256 RAM. But still i got 768mb of memory which is far more better than my 256mb before.

You need to leave more information.  What computer do you have, what motherboard....\n\nHow many slots in total do you have?\n\nIf you have 4 slots, then the chances are you need to insert 2 RAM modules at the same time.  Not a definite, as will need more info on your computer,  but thats probably likely. You could buy 2 sticks on 1GB, and insert them into the currently filled slots, and put the 2 512Mb in the other slots (if you have 4 slots)  That way you will have 3Gb RAM, should run quite will with that!!!

In some cases it matters but with older ram not really. As long as your motherboard supports the speeds it's okay. You computer will take the speed of the slower ram though. So if one ram speed is 133 and the other is 100 both sticks will run at 100

yeah as long as its ddr. 333 and 400 are the speeds. the ram will only go as fast as your motherboard allows. i have a sd 2700 512mb on a 333mhz board. it wont go 2700 but instead slows down to 333

a few systems will not allow you to use faster RAM\nalso ram will only operate at the slowest of Ram or BUSS speed

You're going to have to open it up to put the new RAM inside so why not?\n\nAnyhow your computer supports DDR PC3200 or PC2700 with a max of 1GB per stick. Your computer supports 2GB ram total.

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.
