memory
ok i tried everything. here is a list of what i did
1.powered down computer, removed 1 stick from b1 left other stick in a1, cleared the cmos, rebooted and got the timings from cpu-z.
2.removed stick from a1 and put other stick in a1, cleared cmos, booted ran cpu-z got the timings. both were the same. 2.5,3,3,7,10,16.
3. put both sticks in black slots this time, cleared cmos, went into bios and made sure timings were set to 2.5,3,3,7,10,16. booted checked cpu-z timins were correct still no dual channel.
4.gave up put sticks back in a1 and b1(both blue slot),cleared cmos,rebooted ran cpu-z still says single channel.
now i tried swapping the sticks that were in there like the one in b1 i put in a1 and so on so on still no dual channel. I dont know what to do. right now i am over clocked to 240x10 memory set to 3,3,3,7,10,16. this gives me 200mhz ram speed according to cpu-z but no dual channel. i had this thing at 260x10 prime stable and all that good stuff but i had to run my memory at 166mhz in my bios and my ram suffered badly, couldnt get it any higher that 125mhz according to cpu-z so i back my overclock down to 2400mhz and now i can get my memory to 208mhz stable and system seems faster so i know that the memory "does"make a difference on a a64.so what do i do stay where i am and give up on dual channel til i get some matched ram? also i am running 1t timing.
