| 569277 | 2007-07-16 05:41:00 | It's a MB thing, not dependant on CPU. Many AMD dual channel MB had 3 slots, 1 for 1 chan and 2 for the other. You could run a 512 and 2x 256 in dual mode. Dual Channel for AMD processors was released with the Athlon 64 939 socket, the guy has a Athlon XP 2600+, not DC capable AFAIK..:confused: |

Dual Channel memory was first introduced for AMD on the socket A platform with the nForce2 chipset. Back in those days the memory controller was on the chipset so the memory type/configuration was purely based on chipset choice. |

| 569280 | 2007-07-16 06:13:00 | Only if it is manually set!, most builds will have it as 'let windows automatically adjust..blah blah blah!' nope :p win XP by default sets the min and max size on install and leaves it on manual adjustment. there is an optoin to "let windows adjust" but you have to set that yourself. actually thats an easy way of adjusting it, set it to auto, reboot then see what size it set it to and manually set it to that. |

| 569281 | 2007-07-16 21:44:00 | If the memory is in dual channel mode, it will usually appear on the POST screen with the other memory information. ie. Amount of RAM & speed it's running. Press the Pause/Break key to pause the POST info on bootup. |

| 569282 | 2007-07-16 23:39:00 | it could be a Dual channel issue - but I'm thinking not. Possibly the old / new RAM isn't getting along well and also if you use onboard graphics with shared memory maybe the "rolling" is due to video memory ( i.e. RAM ) being too slow?? - I'm clutching a straws a little. Try your new RAM chip by itself and see how well that works compared too all 3. If it's slower with all the RAM installed than with half of it you either have a compatability or timing issue - sometimes mismatched RAM confuses the motherboard and the automatic speed settings drop back to slow "safe" ones. Also as mentioned it could be related to virtual memory, right click my computer - choose properties, click on advanced then performance - settings - use the "let windows decide" option or manually set a minimum and maximum size of approx 1.5 times your installed RAM ( just as a rough guide ). It's not true that you need more virtual memory if you have more physical memory, it depends entirely on what you do with your system, but more RAM should really mean less need for virtual memory ( in practice though set a reasonable amount ). When I upgraded to 2G of RAM I turned off my virtual memory alltogether and it took a week of using the pc before I discovered a need to turn it back on for a couple of applications. |

Wonder when they changed that, as I know the original build was auto?! |
