Difference Between PC2700 & PC 3200 RAM?
78591
It all depends on what your motherboard will support.\n\nAccording to Intel, it will support either PC2700 or PC3200.  If you have no RAM, get the faster RAM.  If you currently have RAM in it, the other sticks have to all match speeds.  You can not mix 2700 and 3200 RAM.\n\nIt does not support DDR, or anything but PC2700 or PC3200.\n\nBest value is probably getting 2 sticks of 512 Meg PC3200.  Normal street price is around $59 per stick.

It is actually very easy to add RAM to your system.  (Technically, the CPU is the main chip, even though many people and computer classes will tell you that the whole "box" is the CPU).\n\nAdding RAM is about the easiest upgrade you can do to your system, and is usually the most cost effective performance upgrade you can do for it, if it is a fairly recent system.\n\nIf you don't know what RAM to get, and don't have the books for your system, I always suggest www.crucial.com to look.  There, you can look up your system and exactly what RAM it takes.  Plus, if you choose to buy from them, they have decent prices, and they also guarantee compatibility with you system.  On top of that, the RAM is of top quality and is often used by the big name system manufacturers.\n\nThey even include good instructions to tell you how to actually install in (usually, you just snap the module in place).

Here's a quick cost breakdown to help you decide:\n\nMemory upgrade:  Your system most likely takes PC133 SDRAM.\n\n2 x 512MB modules at $75.00 each =  $150.00***\nhttp://www.buymemory.com\n\n***Careful, not all P3 1GHz machines accept 512MB modules, ask about compatibility before you buy.\n\nNew hard drive:  7200RPM ATA 80GB-100GB about $50-$60\n(Any online source with good customer service)\n\nTotal upgrade = $200-$210\n\nOR\n\nNew P4 2.8GHz or higher with 512MB RAM and 80GB drive or larger for around $400 (sometimes with flat panel monitor for about $450)\n\nUpgrading will definitely help your PC, however, you'll grow out of even that in a hurry with graphic design.  I highly recommend a new PC to preserver your sanity and save you money in the long run.  You'll want a large hard drive, but can always buy a seperate drive for storage later, they're getting cheaper each week it seems.\n\nSometimes it's more expensive to upgrade memory during the PC purchase instead of ordering somewhere online.

Appears to be DDR Ram PC2100 nonECC\n\nhttp://dealnews.com/memory/prices/systems/Compaq-Presario-s4020-wm-PC2100-DDR-266-MHz/32284/128MB.html

T2400 runs at 1.833GHz\nT2500 runs at 2.000GHz\ndo the math\n((2000 - 1833) / 1833) * 100 = 9.11%\n\nit's not worth to upgrade from T2400 to T2500 (it's $120) according to the prices from newegg\nhttp://www.newegg.com/Product/ProductList.asp?N=50001157+2000340343+1050719930&Submit=ENE&Subcategory=343&Manufactory=1157\n\nyou better upgrade the Ram from 1GB to 2GB\n\nedit:\none thing to remember. the Core Duo processor doesn't support 64bit operation (EM64T is not implemented like in the P4 series 6xx) so you can't upgrade to Windows Vista.

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.

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.

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.

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 wont be much of a difference between 384 and 320. I think the display will say 320, but your computer is actually using all of 384. You dont need to worry about it.

C.L 2.5 is the CAS Latency of the RAM, it is a bit complicated for a novice but if you really wanna know what it is take a read:http://en.wikipedia.org/wiki/CAS_Latency\notherwise just know that the lower it is the better.\n\nAs for how much it will take, it will obviously take two, its hard to know how big it will take for sure, but I can say with almost certainty it will take at least 512MB sticks, so you can get two for a total of 1GB.  I would recommend you go to crucial.com and use their memory tool to be sure, or see if you can find your model number and email it to me and I can look it up.\n\nAnyway, assuming all works out and it can take 512 sticks, I would recommend purchasing this:http://www.newegg.com/Product/Product.asp?Item=N82E16820220057\nIt is good quality for a good price.  Just take out your old stick and replace it with these two.  Its speed is higher than yours currently, but that is okay as the RAM will automatically slow itself down to meet your requirements, and if you are lucky and your computer will support it will be able to run at the higher speed.\n\nIf you need any further help, please feel free to email me.

Go to www.crucial.com  (a memory manufacturer) and use their Memory Advisor Tool.    You select your computer's brand, model, etc.  and they tell you exactly what to order.\n\nThere are lots of different models, but there are subtle differences, so don't order anything just because it looks "close".    Although some of the "close" ones will work, sometimes small differences will make big differences in performance.  \n\nIt's better to spend a few extra bucks for something that is an exact match for your pc.    It will last a long time!

Make sure your mainboard supports the proper ram, there are different types of Ram SDRAM, DDR,DDR2 and come with different pins 189 or 249 Pin (PC3200,PC4200,PC5000...).\n\nInstalling Ram isn't quite that difficult, but you may damage the enitire Ram Module or Other components if you are not careful. I recommend a static wrist band during installation. Make sure you release the RAM Slot locks on the board, insert the ram module using both your hands, then by applying little pressure with both hands close the locks, visually check if the Ram is seated properly.

RAM is temporary memory - but using your max amount is going to make your computer run funny.

PC2100 is all this machine needs so pc3200 is overkill. On the otherhand it should work ok just wont be clocked at full capability.

LOL DDR and SDRAM are two totally different things.  DDR is Dual or Double Data Rate.  SDRAM is Synchronous Dynamic RAM.  You can have DDR SDRAM.  You need to find out if your computer supports DDR or SDR (single data rate), then see what the max allowable size for each memory bank is on your PC.  If it supports up to 512MB and DDR, you should be able to use it.  Also, the speed comes into factor.  What speed of RAM does your motherboard support PC 2100, 2700, 3200, etc?\n\nDDR SDRAM\nSDR SDRAM  \n\nconfusing because of the SDR acronym in both Single Data Rate and Synchronous Dynamic Random...  this is why you are getting icorrect answers.
