Ram Timing Set with modules in slot 1 and 3 running unganged.


Whenever i try to run in dual channel mode with the memory sticks in slots 1 and 2 or 1,2,3,4 my computer will not post.
Does anyone have any idea why this is?

What about 3,4? also, try 1 stick of mem at a time. see if one is bad. sounds like a bad stick somewhere, any beeps or error messages would help.

I put each of the four stick in slot one and each individual dimm posted. When i had the memory in 3 and 4, it would not post. However while trying to post, the fan which i believe was the cpu fan was pulsating slightly. You could hear it ramp up, stay at a high rpm and then come down a little bit. This would repeat like it was hunting. I don't think the memory is bad unless it can go bad in dual channel and work in single channel. Could that be possible?

 

[casualbuilder]

there may be bad RAM slots on the board, check each slot with 1 stick of ram, and see if there are any issues please note here.

 

[daloia20]

Slots 1 and 3 work while slots 2 and 4 do not with a single dimm of ram. Does this mean that my slots 2 and 4 are dead?

 

[casualbuilder]

yes sir. no bueno. RMA the board, and get one that has all dimm slots working.
