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.
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
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.
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.

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.
