I bought memory for a friend's desktop PC (an AcerPower F5). Every memory configurator I used pointed me towards DDR2 533 (PC2 4200) with a maximum of 2 GB (2 slots, 2X1GB) but I've bought two different sets of ram for it (first a PQI Turbo 2GB kit with a CL 3 then Kingston ValueRam with a CL 4) and the PC wouldn't boot or post with either (any) of the new sticks. Upon closer inspection, the motherboard does have DDR2 667 stamped on it in small white letters. Before buying a 3rd (and most assuredly final) set of ram, I wanted to see if anybody could shed some light on something I might be missing. Is the answer in front of my face -- 667 is the way to go and anything slower won't work?? ...or am I just generally jinxed and/or doomed? Please help!
Ive had the same problem upgrading the ram on 2 acer pcs in work, we have 4 of them in total,2 took ddr2 667 mhz 1 gb crucial brand ed ram sticks, the other 2machines however wouldnt take the same chips and exhibit same symptoms as above even when original chips were put back, drives spin at 1st, fan blowss but no signal to monitor and no post codes. turning the pc on and off a couple of times get the machine booting but inevitebly the machine will freeze after sometime in windows. weird eh,
Just to make sure, you are UPgrading the RAM aren't you, it originally has 1GB in it, didn't it? Because i Hate people that change things when it is unnecessary. But you are right it helps to look at the little label on the RAM you took out as to what kind to get, try to get the same speed will probably guarantee it will work.

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.
According to specs, your computer can use up to 4Gb of memory. You will need to open the case and see what is currently installed. You should have 4 memory slots and probably it came configured with 2 512Mb memory sticks. You could add 2 more sticks of 1Gb each bringing your total up to 3Gb, but my suggestion would be to remove the existing memory modules and install 4 matching 1Gb modules. You must use DDR2 PC2-5300, DDR2 (non-ECC) type memory and the best results will be achieved by using all matching modules.
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.
Number of Slots: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
In order to upgrade the ram of your desktop. First you have to check the ram specifications. If wrong specifications the desktop will not work. To check you have to remove the ram from your desktop by removing the screws behind your desktop. Open the lid and you will see the contents of your desktop. Besides of your processor, there is ram installed. Unclip it. Then bring that ram to the computer shops. Purchase a ram higher than the ram installed in your desktop. Afterwards, install the new ram to your desktop. Good luck.
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.

Choose the following Memory Upgrade for eMachines eMachines T5082 Computer.
as you can see from the information below there are different requirements for RAM to work stable in your system . Most importand are the RAM VOLTAGE , SPEED , and Configuration of chips. you will need to consult the manual for qualified RAM requirements. Some RAM will work but not very stable. make sure the voltage supplied by your system is enough for the RAM. If you are running DDR RAM in dual channel mode, the ram needs to be the same size also.DIMM modules for the HP computer must meet the following requirements
The number of pins on the DIMM must match the socket type.
DDR memory requires a 184-pin slot and 1.8 operating voltage.
DDR2 memory is not compatible with DDR1 memory and requires a 240-pin slot and 2.5 operating voltage.
Synchronous dynamic random access memory (SDRAM): Only use DDR type SDRAM memory if the computer came with DDR-SDRAM.
SO-DIMM modules for the HP computer must meet the following requirements
The number of pins on the DIMM must match the socket type.
SO-DIMM memory requires a 200-pin slot.
DDR2 SO-DIMMs are not compatible with DDR1 DIMM and DDR2 DIMM memory modules.
With a computer running at a system bus of 533 MHz or 667 MHz, use a PC2-4200 (DDR2 DIMM 533) type.
The following requirements must be met for the DDR memory to function in dual channel mode:
Same density (256MB, 512MB, etc.)
Same DRAM chip technology (x8 or x16)
All either single-sided or dual-sided
Matched in both Channel A and Channel B memory channels
