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.

To clarify, this is a memory upgrade necessitated by frequent "OUT OF MEMORY" errors.
Also, you are correct: the PC came with 1GB ram. However, aiming to maximize compatibility and reduce the likelihood of other unforeseen problems, I made the decision to utilize a matching pair rather than simply purchasing an additional stick of ram to compliment the existing one.
The existing stick is generic with no discernible markings.
