Computer memory compatibility problems

My home computer DDR333 256MB of memory is a telecommunications joint 1 trillion of ADSL, was found card, so I had to buy a gold-CSF 1GB of DDR400 memory, and found the installation of speed up a lot faster, run as Karting This 3D game can be played! I used CPU-Z has been poor, found that the frequency of 133.6 memory! I would like to ask, the original 256MB of DDR333 is not necessary to go by? There will be any compatibility problems? Does not go by there will be any compatibility problems?

there is no need to install them, no use to install up not compatible, the memory must be unity compatible embryos at a unified model of the `Do not Zhuangshang Qu ..Zhuang Shangqu of DDR400 memory will be down to DDR333 Use.Moreover, there is not very different from that 256MB has been, at least for you, this is the case ..

but rather strange that “the memory frequency is 133.6,” 133.6, is the only DDR266 , How is the DDR333 ..is not recommended, 333 and 400 are not compatible, said that the basic 1G good enough for us, in more than 256 that also does not matter, if you have an memory will go up, then down, but if you have two Memory is not the same make, model, may be incompatible, if you use up enough, or to suggest that you DDR333 256MB of memory sold it.Do not install memory in general computer models of different frequencies of the two together, give rise to Hardware is not compatible with the situation a lot! Is not recommended to install the 333 FSB memory of the original 256MB of DDR333 is not necessary to go by?

If you like so much on the capacity of 256M Zhuangshang Qu Ha ha

there will be any compatibility problems?

give it a try, do not know, and if so, pull down on

not go by there will be any compatibility problems?
Only a memory, how will be compatible with the problem, unless you choose board memory, speed and DDR Oh all right, and Kim Ritter DDR400 and DDR333 256MB of your original with this completely different, it would create more slowly, and suggest that you Removed DDR333 256MB, only DDR400 1GB so that the faster.Loaded with non fitted in general it will not matter, but suggested that more memory is one of the best brands of a type of memory.Even if there are problems, that is, Blue Screen of Death or the problem will not be very serious problems after you pull it down on the line.
