so i bought a new processor to fix my memory controller, and when i put the two 1gb ram on slot 1 and 2 i get dual channel, but when i put it on slot 3 and 4, which is suppose to be dual channel, but all i hear are just beeps. which is kind of weird.
i also have 2 512mb, i tried setting up 3gb dual channel, 1.5gb on one channel and another 1.5gb on another channel, but all it posts is 2gb single channel, which is weird, i ran cpu-z and it said that slot 1 is 1gb, 2 and 3 are 512mb which the 2nd slot is suppose to be 1gb, and slot 4 was empty, but i had all 4 of my ram on all the 4 slots, whether or not the timings are the same (I'm sure the speed is the same) but shouldn't it post as 3gb single channel? me and my friends tried moving them around, and sometimes we get beeps, sometimes it don't post at all, and sometimes all it said was 2 gb.
one time i got it to read 3gb in my bios, but after logging into windows, i ran dxdiag and cpu-z and it says that i have 2gb, so i restarted my computer and went into bios, and it posted back as 2gb. i ran the memtest 10 times on each stick before and they all passed 10 times. my DFI manual says it could hold up to 4gb
any ideas on whats wrong?
p.s the information on my rig is on my sig
thanks in advance
