Can some one tell me the advantages and disadvantages of installing only the 512MB DDR400 running at 400Mhz?

It'll b much faster. Ur computer will hog less & will allow u 2 work 2 or more programs at once. Disadvantages r da cost & some times da power usage of it

Don't buy the faster chips because all the motherboard will do is clock down the PC3200 chips to PC2700. Noboday needs 2GB of ram unless you are going to run a SQL database on it or do really graphic intense animation or something like that. The reason why the board will clock it down is because the motherboards bus will only go as fast as the PC2700 chips. Get 512MB or up to a Gig that will be perfect!

as an example if u have p3 the internal speed of the ram is 133 Mhz , and for P4 is 400 Mhz or 800 , that means all parts shall be compatible to each other in order to get best performance , also memory will go in double capacity , 128, 256,512,1028 , u cant add 128+512=640 its not really wrong but how money can the add memory worthy

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.

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.

Nope, it is not, it runs in parallel, for instance  333 DDR DC runs at 133 MHZ through two channels, for a total of 266 MHZ.  It is over clocked to output 333....\nKeep this in mind:\nWhat are some of the benefits of using paired memory? Since the memory sticks are packaged together after they have been tested together makes sure the modules that the end-user receives will be stable and perform well. Mixing different memory could lead to system instabilities or the memory modules might not run together due to compatibility issues. This takes the guesswork out of choosing memory for a dual channel motherboard. In addition, we feel that since memory speeds are not getting much faster, this give memory manufacturers another stepping-stone before moving to faster memory. Recently many other manufacturers have also started producing these paired memory kits.

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.

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.

Some of these answers are wrong and others are not clear enough.\n\nYou need to first check with either the PC maker or motherboard manufacturer and see:\n\n1. What is the total amount of memory supported by the board?\n2. Does this memory have to be installed in pairs?\n3. What type of memory am I currenty running so I don't break Double DDR by installing a single DIMM\n\nBasically your usually better off with multiple chips rather than a single large chip. Your cost per MB is usually lower this way plus if the system is designed to use multiple channels you get added bandwidth by splitting the memory into seperate banks on seperate busses.\n\nCrucial has a pretty good web site for finding out what memory your system can take but don't take that for gospel.

Of course you'll se the difference! Not mainly in speed but mostly regarding the entire ysstem stability.. The only problem is that at this time many applications are still written in 32-bit and eventualy don't support 64-bit applications. It's the only disadvantage, and I could say minor because very soon 64 bit will be the new standard for cpu processing!

DDR2 has a faster data rate, faster bus frequency, it uses less voltage, it's prefetch size is 4 bits instead of 2bits that regular DDR has. It's all around faster.

If you have the mother board on an intel chipset then it will take a percentage of ram by itself.\nYou cannot change that Neither is it required

Okay...  The difference between a 3.0 and a 2.8 is negligible.  However, if the 3.0 were tapped with HT, or Hyperthreading, the difference would be enormous.  Hyperthreading virtually turns one processor into two.  It will significantly increase the PC performance when it comes to multi-tasking.  Look for it.\nFSB... or Front Side Bus...  Imagine a funnel.  The CPU speed, like 3 GHz, would be the top of the funnel.  The FSB would be the bottom.  No matter how big the top is, the bottom can only allow so much out at one time.  There are FSB's up to 2000 now.\nMemory... the speed is what you're looking at.  This means that the memory clock is set at 533 MHz/sec.  The higher the speed, obviously, the faster information can be retrieved from memory.  The DIMMs are the number of slots availible.  If you have 2 DIMMs, then you have 2 slots for memory.  A maximum of 2 GHz of memory is availible.  At 4 DIMMs, your maximum is 4 GHz.  The more memory, the faster you can get programs to load, or the less lag you'd see in high res games.\nHard Drive...  As a hard drive reads its disks, it writes information to the cache.  The larger the cache, the more information you can access before the HDD has to read more.  So, the higher the Cache, the better.  As far as RPMs, this is the speed at which the disks spin, and logically, the higher the RPM, the faster the HDD can access new information.\nYour options are all dependant on your budget.  You will get great performance with the 2.8, with 512 Megs of memory, with a 7200 RPM hdd with an 8MB cache.  But, the more you can afford to put in it, the longer it will take before you are way behind tomorrow's technologies.\nIf you have further questions, feel free to email me at this yahoo screen name.

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

yah it shoudl run without any issues make msure you have more than 512 MB RAM.\n\nkshounish

No there's not a way around it I'm afraid, you'll have to buy more memory. The good news is it'll be cheap for you, probably less than your monthly broadband subscription as you probably have an older system. If you post your RAM specs on here or email me I can tell you what you need and how to install it into your system

that's not really an upgrade, just a very slight incline grade (like about 1 degree from horizontal)\nget a single stick 256 or 512\nthe ram will not work faster than your system will allow it to
