For the Video board, it depends on how you are going to use the unit and how much you want to spent. GeoForce video boards are great.

copy and paste the link into your browser.
If I could be of further assistance, let me know. If this helps or solves the issue, please rate it.
Thanks, Joe

Can I use DDR400 (PC3200) RAm in my Dell OptiPlex GX260 PC Desktop? Thanks


Yes.

Maximum Total Amount is 2GB.
Maximum Amount for EACH Ram Memory slot is 1GB.

Use unbuffered, low density, Non-ECC.
2.5 volt to 2.6 volt
Chip configuration is 128Meg X 64 for a 1GB ram memory module.
(Ram memory 'stick')

Suggest you watch where you buy it.
Cheap costing ram memory = cheap quality ram memory
Doesn't have to 'break the bank' in cost, but if it's too cheap to be true, it usually is.
Buy from a reputable ram dealer.

RAM compatibilty


No, DDR 400 will not work. The best thing you can do is call Dell and give them your information. Model number and that kind of information and let them tell you what kind of ram you need. If you put the wrong type of ram in your machine it could cause major damage. There are so many different kinds of memory out there, not to mention high and low denisity. Your machine may use PC2700 high density and if you try to use PC2700 low density it will not work. One other thing that you can try is uninstall a stick of your ram and write down everything on the stickers and then go to some place like kingston memory and use their memory locator to find what you need.

Tried to upgrade ram with 2 new pc133 sticks of 256mb ea. Didn't work. What's wrong? Are there switches on the motherboard I need to change? Or something else?


No there are no DIP switches to change, or jumpers to move on your motherboard, in regards to your BIOS recognizing ram memory installed.
(BIOS. Basic Input/Output System. This tiny program, {64MB in size usually}, that is burned into your BIOS chipset, is what recognizes ram memory on your computer)

Things to know about the older Sdram ram memory.
1.It's really SDR Sdram. Single Data Rate Synchronous Dynamic Random Access Memory.
DDR is Double Data Rate Sdram, DDR2 is Double Data Rate 2 Sdram, and so on.

Point? All ram from SDR to DDR3, IS Sdram.

2.Standards have been set by JEDEC for computer ram memory starting from DDR Sdram on up. This standards were not implemented back in the day of SDR Sdram.

Point? Ram memory manufacturers didn't all follow the same standard, and ram memory made for one computer, would Not work in another computer.
This means you need THE ram memory for YOUR eMachines computer.

Main factors when buying SDR Sdram,
A.Correct type. You know this. SDR Sdram.
168 gold plated contact pins on the bottom of the ram 'stick'. (82 on each side)

B.Correct 'Speed'. ('Speed' is slang for Frequency Rate) You know this. SDR Sdram that operates at a frequency rate of 133MHz. (Or also known as PC133)

C.It must be low density Non-ECC ram memory. It cannot be high density ECC. (Error Control Correcting. Used for Server computers mostly)

D.Correct CAS Latency. Also known as Ram Timings. 3-3-3-3-2 would be normal for SDR Sdram.

E.Correct Chip Configuration. How the DRAM chips are accessed. DRAM chips are the black rectangular chips on each side of your ram memory 'stick'. Also what size the DRAM chips are in MegaBytes. (MB)

F.What the Maximum TOTAL Amount is for the motherboard. Is it 256MB? 512MB? Or more?

G.What the Maximum Amount is for EACH ram 'slot'. (Correct speak for 'Slot' is Bank)

H.Do you have four ram 'slots'? You MUST have a ram stick in Slot 1. This is the slot closest to the processor. It is the first ram slot the processor 'reads'.

I tryed to restore my emachine w1800 with my restore disk and when I reboot a blue screen comes up a problem has been detected and windows has been shut down to prevent damage to your computer. If this is...


could be a couple of things, usually when you get the BSOD (blue screen of death) there is usually a ram problem, have you noticed your pc getting slow, sometimes the ram sticks break down over a period, try getting hold of a memory tester software and checking the PC, this is usually done through the inital start up before windows is loaded, please ensure though that if you need to get more ram that you use the correct one for your motherboard, buying incorrect ram can cause more problems and is a waste of money, www.crucial.com is good for checking ram in pcs, also you need to make sure that if it says low density you use low density ram, or high density for high density. also make sure that you buy the one with the correct amount of pins.

hope that this helps

When ordering ram memory for wifes computer


Go with Crucial. I recently used then as the vendor to get memory for a middle school and all of their memory fit with no problems, the shipping was fast and the scanner worked with new and old computers. I would go for the pc2700, although your wife's computer can take both types, faster is better and the higher the number the faster the ram.

My laptop has 256K memory installed. I purchased 512 RAM (max I can add is 1024) and installed it in my hp Pavilion zt1230 laptop. Per Kahlon.com instructions, I cleaned gold leads with eraser and popped...


Is it a High Density memory? There are two different types of memory, High and Low. Low density is the universal but High density, may be cheaper but the motherboard needs to be compatible with High density memory. Although your memory fits in the slot, I think you have High density memory hence why it won't boot up and does when you remove the memory.

Few questions about RAM memory?


Solution:



i)  LOW DENSITY modules have 100% compatiility with ALL systems and ALL chipsets.
    HIGH DENSITY modules only have 10% compatibility

    here compatablity means LOW DENSITY RAM are accepted by all system(100%)  or any make           system.. HIGH DENSITY RAM are accepted by 10% by only some system or computers...


ii) in order to check system performance or amount of Computer RAM usage press the ctrl+alt+del
   simultaneously a new window(window task manager) will appear showing:

    CPU usage: showing the amount of CPU or processor utilized at that particular time.
    PF usage: showing the amount of RAM memory utilized at that particular time.
    Physical Memory: showing Total RAM Memory, Available Ram memory....

iii) baiscally they are two types of RAM they are:

    DDR1:which is older one supported by older system  or older mother boards which is costlier
    DDR2: which is latest one supported by all new system or new mother boards which is less                         costlier

    DDR: double data rated ram......which will send data at a double rate compared to SD RAM

iii) here color doesnt matter, these slots either support DDR1 or DDR2 but not both at a time
    
    DDR1 has 184 pins or gold plated pinssss... on the edge of the RAM
    DDR2 has 240 pins 

    so difference doesnot allow DDR2 to placed in DDR1 motherboards or vice versa...

iv) it does have anything to do with no of chips on the RAM but they only differ whether it is DDR1 OR DDR 2(DDR2 are much faster than DDR1)

NOTE: whatever may the the RAM, each RAM has FSB(called Frequency...) which determines the frequency of rate at which data is tranferred from RAM to processor(CPU)  usually in MHZ such as FSB 300, 400, 200 , 333...................

more the FSB the faster data is transferred to the processor(CPU)

dont worry even RAM with less FSB's work well with the processor....having 1 GB RAM or 2 GB RAM is engouh, it only matters with the speed of CPU ... but not RAM......

Emachines T2240


low density works alot more often then high density, HD is just cheaper and thats mostly why it't not compatible with as many boards.
Good luck,

Emachine w3118 memory


while the reason you want to know density might help to answer, if you are buying memory you only need to know it will work in your machine

when I bought memory for my computer I googled brand and model number with the word "memory" and found a seller that had a little tool I down loaded and ran to tell me what memory was needed

memory is very cheap now days so price compare before you buy
