Just a quick question about upgrading the Memory on my Home PC, it currently has a 256mb DDR card in it, I was thinking of upgrading to 512mb or 1GB, the question is does it matter what mhz DDR card I buy? Obviously a 400mhz is going to be better than a 133mhz but do I need to add something specific to the Motherboard? I have found some 400mhz 512 cars for £25 which seems good or 1gb for £40ish, I will be removing the 256 as I understand you can't mix the cards....

Need a simple answer as my knowledge of computers is limited....

Thanks.

Is your current 256Mb stick a 400MHz piece or a 133MHz piece? The 2 types are not compatible and if your motherboard takes one type, then it will not take the other type of memory.

The easiest way to find out what you need is to go to www.crucial.com/uk/ and click the 'Scan My System' button. It will tell you exactly what you have and what you can upgrade to.

Upgrading memory is a bit of a minefield. Quite simply for the sake of your sanity the best thing to do is to keep the same type of RAM you have and add another module (depending on free slots) or replace existing one with same speed but higher capacity.

www.crucial.com/uk/ has already been mentioned, it is well worth using.

u don't need to buy it from there, but would suggest dumping the 256 mb ram and getting 2x 1 GB sticks of the same type and that are compatible with motherboard, hence the website above.

got a few smaller sticks, think they were 2x 512 mb, which seemed a good idea at the time. next pc gets 4 GB
