Does "matched pair" mean that every stick of ram has to be the same size, speed AND brand or just the same size and speed
E.G:
2 Crucial 1GB PC2-6400
+
2 White Box 1GB PC2-6400
Would This configuration work or would I need 4 Crucial 1Gb sticks etc? :s
If the specs are the same (voltage, timings etc...) then they will work fine together :thumbsup:Quote:

a good tip is to install CPUZ as that will tell you amongst other things what speed, timings and voltages your memory will do, basicaly reads the firmwear of the memory, can`t remember exactly what its called sdp,spd but I`m sure some1 will know round here and post it ........ I hope ;)
To me all 4 ram sticks should work fine together = 4Gig but if you are running a 32 bit os and have a 512Mb GFX card u will only get 3.5 Gb in windowz its even worse if you GFX card has 1Gb of memory as then U are basically wasting a ram stick
Matched pair used to mean that they were literally next to each other off the production line but unless you are trying to squeeze every nth out of an overclock you really will not notice the difference. The important thing as the chaps above have said is that the speed, voltage, timings are the same. And make sure they are the same size and in pairs of the same type as if they differ you may not make full use of the Dual Channel features and so it will just run slower than the board is capable of.
The quality of the ram is also important as it aids with stability. The more expensive ram basically is the better pick from the production line hence you see Mushkin, G.Skill brands at higher prices vs the Crucials and Kingstons. To be honest for a regular non-clocked system most are fine but always check your board compatibility with say Crucial`s online tools first just to make sure :)
Cheers,
Matched PAIRS. You can use a pair from one brand and another pair from another.
Check the documentation of the mobo to see the way you must hook the sticks. On my board I had to use socket 1 & 3 for one pair and 2 & 4 for the other. Works a dream.
Of course, remember the memory sticks must be the same specs or you'll have to force the best pair on the lower specs of the other pair.
Boards with only 3 memory slots must have three sticks exactly equals.
Even If I have a grapics card with its own memory rather than system shared? :sQuote:

I would go with what the board manufacturer and manual tell you :thumbsup:Quote:

You still need 64-bit versions of Vista & 7 to utilise more than 3gb of RAM.Quote:

Its crap that the 64bit versions on windoz are crap for gaming
