RAM Upgrade for AcerPower F5

in win 7 it won't shows all RAM, mostly virtual and paging file uses it,don't worry your ram is fine.when cpu require high RAM usage it uses it.

was your vostro 230 third generation? meaning, did it use DDR2 memory before or always had DDR3? They are not compatible. 2nd generation computers cannot use third gen parts. cpu, ram, most none of that type stuff. the motherboards are different and cannot change. if it was ddr2 memory you have to use ddr2, not ddr3, hope that helps.

as long as the socket is exactly the same as the processor you are trying to upgrade to you should be good. As far as memory goes you can use a faster ddr2 chip but you have to find out what the maximum capacity is on each slot. Most newer computers can support 1gb+ per slot. Always make sure you install ram in pairs and in the proper slots.

Hello
Number of Slots:4
Slot 1 Slot 2 Slot 3 Slot 4 Each memory slot can hold DDR2 PC2-5300, DDR2 PC2-6400 with a maximum of 1GB per slot.
Not to exceed manufacturer supported memory
Good Luck, and do rate the solution if got help

If its a desktop it should be fine with two 1 gb sticks. Check to see how much ram is being shared for video. You can see that in the bios setting. Not sure how much can be shared but it may read differently depending how much system ram is being shared for onboard memory.

DDR 266 is DDR, not DDR 2 . The 266 is the frequency value in Mhz.

Try having the memory refunded or resell it on Ebay, so that you do not lose your money.

Here is supported memory, many older motherboards do not accept modules of over 512Mb each, ask to the seller:

PC2100 Memory DDR266 DDR-266 184-Pin Upgrade (266MHz) Memory Upgrades

The rule of thumb with RAM is to always buy matching pairs. So instead of buying one new stick of 1gb its a better idea to buy two of the same kind and replace the one that is currently in there.

Before you even think about doing this, head over to lenovo's website and make sure that the computer is compatible with 2gb(from the speed of the ram im assuming that it will, I don't know of many DDR2 computers that cant have 2gb.) you may also be able to get ram that is faster if it is compatible, The website will have all this info.

Hi there.
I recommend you get another stick of SODIMM to replace what seems to be the faulty stick.
If you are using XP or Vista X86 (32bit) then the system will only recognize 2.8 - 3GB of memory, only 64bit operating systems recognize the full 4GB.


Good luck ad thanks for using FixYa!!

I had the same issue on this board where it came with a Samsung 512 MB 533 MHz PC2-4200 DDR2 DIMM. I put in a 1 GB Kingston with the same specs (533 MHz PC2-4200 DDR2) and it would not recongize the Samsung anymore with the system reading as 1 GB of RAM instead of 1.5 GB. Tried every configuration and would only see the Kingston. It would only see the Samsung if I pulled out the Kingston regarless of the slots I use. So, I just bought the exact same make/model of Kingston and it recognized that fine and the system now has 2 GB of memory (max this board allows). And, I had already installed the latest BIOS for this board from Intel before doing all this so wasn't an old BIOS. I'm figuring the board didn't like something about the Samsung memory (speed, module configuration, etc.) that made it not play nice with the Kingston. If interested I bought the DM8400A/1G Kingston modules. And, this board appears not to support dual channel memory. Only has channel A, slots 0 and 1, and I read need two channels to support dual channel (seems obvious). Boards that supports dual channel memory normally have 4 memory slots, two for channel A and two for channel B, then put in matching modules in slot 0 for channel A and B and have dual channel memory access. And if want more ram, then matching modules in slot 1 for channel A and B.
