I have (as many will know) recently built an A64 system, but I only had 1x 512Mb stick of Ram. Yesterday I received another 512Mb stick, hoping to get Dual channel running.
Alas, DC will not work (can't get it to POST at all), but it does boot if I insert the sticks in single channel mode. The only problem with that is that CPU-Z now reports my memory speed as exactly 1/2 what it should be!
For example, If I set the HTT to 200Mhz (Stock), and set RAM to 200Mhz, with both sticks in CPU-Z claims the RAM is running at 100Mhz. WTF?
Another example which suggests the RAM is actually running at this speed (and it's not just CPU-Z misreporting) - HTT at 250, RAM set to 1:1, ram shows up as 125Mhz, whereas I could never get it to boot at 250Mhz when I only had the original stick in there - anything above 240 didn't work, and 240 required <i>much</i> slacker timings than it was happy with here (at '250')...
I've had a look on the 'net, and flipped through the manual, but can't find any mention of this anywhere....
I didn't have the time to do any benchmarking, and probably won't really until saturday, so I haven't been able to confirm that it's definitely running slow, but it seems to be.
Any thoughts?
Current settings: (IIRC)
A64 3200+ Winchester, 2580Mhz (258x10), HTT 1032Mhz
512Mb Corsair XMS4000, 512Mb Crucial Ballistix PC4000 single-channel, ~108Mhz
