can a ddr400 works on ddr333?
817072
you can add a DDR400 to a DDR333 as long as the two RAMs are of the same size, ie., 512 MB each for example. there will be a speed mismatch and nothing else.

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

333MHZ refers to the max speed at which ur RAM can function. PC2700 is the standard to which the DDR memory is compliant with. so by putting both together on the RAM stick, the manufacturer  makes sure that u have all the info u need.

DDR2 DIMMs are not backwards compatible with DDR DIMMs. The notch on DDR2 DIMMs is in a different position than DDR DIMMs, and the pin density is slightly higher than DDR DIMMs. DDR2 is a 240-pin module, DDR is a 184-pin module.

DDR2 is double the bus speed, so if you laptop supports it, and you can afford the extra price, use that.  Your system will recognize it w/o problem (again, if it supports it).  Some systems only support DDR, so you need to be sure - go to http://welcome.hp.com/country/us/en/support.html and enter your model number - then look at what memory upgrade is supported.  If DDR2 is not specified, you have to get DDR.

DDR RAMs will not fit in a SDRAM slot. For utmost details:\nhttp://computer.howstuffworks.com/ram.htm

Yes and No. I own an HP pavilion 8775c with a 933 P3. You realy need to post more info. A modle number would be great.\n\nAnyways, In my case I did a BIOS upgrade. This allowed my board to take a 1.3 celleron I think. The board has jumpers to set voltage, buss and multiplier setting. Problem was in my case and possibly in yours, is that HP takes the jumper pins off and just solders the connections in the possition they want. This means, even if I had that 1.3 it would still show up as a 933 P3. If you want to do an upgrade and have limited funds, I have a few recomendations.\n\nFirst off, some one I'm sure will come around and tell you just to buy a new system. I'm still using my HP P3. It's heavily modified, but runs great and it can still keep up with these new systems. Get an aftermarket Mother Board. An Asus would be good considering they already make the one in your HP. This is why more info would be good. If your CPU is using SLOT 1, this part may not apply to you then. If you're using Socket 370, then try and find a Socket 370 board. Get one with the highest possible CPU support you can get. This way, you can keep all you're current hardware. You can usualy find a good new board on Socket 370 for about 30 to 60 bucks. Then, just spend another 20 bucks on a better heat synk and fan, and over clock it to 933 or 1Ghz if you're feeling lucky. \n\nIf you're on Slot 1, this may be a good time to switch to AMD. LOL

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.

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

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

Yes. DDR 2100 equals to DDR266. Its not DDR2100, but PC2100. 2100 is the thoroughput/bandwidth, 2100MB/second, and 266 is the speed (266 MHz effective, 133MHz X2 because its DDR (Double Data Rate)). So its PC2100 and DDR266. Don't mix them up.\nDDR333 is PC2700, and DDR400 is PC3200.

As long as the motherboard supports both ram..but its not going to improve much having the 333. It will not harm the memory.\n\nI would stick with the 1gb...if you find yourself needing more ram then you can put the 333 in but note..it will decrease the speed at which the memory operates.

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

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

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

Yes I have a Sempron Sad to say and you can Mismatch any type of PC3200 DDR 400 in a sempron all you have to do is add it in a available memory bank and if one is not available you will have to take a old one out and replace with a higher capacity one.

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.
