    2GB 6400 is clocked faster than 5300, so the 2GB of 6400 would be the quicker. As to whether you're going to notice any difference in real terms - extremely unlikely.

    If you were opening large applications or many applications, that additional 512MB may come in handy...

    Partly depends on CPU, due to AMD DDR2 memory controllers being built into the CPU, and Intel ones (ie Core2) being on the Northbridge. All are on-die now with PD, Trinity and Ivy Bridge. For AMD, should be about the same, 2.5GB should be tiny bit better for intensive application use. For Intel, get the quicker RAM IMO.

    IMHO, this is the key. Reading from HDD, even SSD's, is slower than the difference between 5300 and 6400 RAM. What OS are you running? Is is 32bit or 64bit? What applications are being run? How many and what might run simultaneously? What kind of data are you loading into those apps?

    These are more important questions. In short, go with the extra 512MB!

    I have gone with the extra 512. Basically we have some older HP laptops that have 2gb 6400, AMD Turion duel core (not sure on speed at the moment) but I have a batch of 5300 512mb going spare so have been fitting one into the spare slots in each of the HPs. They are only used as standard laptops, nothing special, 32bit W7 on RM CC4.3 network

    I think you'll be better off with slightly more ram than slightly faster ram. + if it's DDR2 then it will dual channel the first GB

    Run Memtest on one to confirm the MB/S throughput and channel mode.

    Yeah with Turions the extra RAM will probably be better, the memory bandwidth doesn't make much difference with them. I remember seeing an extensive (Tom's?) test done on this with that generation of CPU, AMD and Intel. We have a batch of older HPs with Semprons, work well with 3GB of PC2-5300. Would love to put Turions in them all, but it's an Ebay job one-by-one!
