CMZ16GX3M4A1600C9 and CMZ8GX3M1A1600C10 don't play nice :-(

[MagnusT]

I've checked your compatibility chart for my MB a Gigabyte GA-Z68MX-UD2H-B3 and both these are listed as supported:

 

CMZ16GX3M4A1600C9 16GB (4x4GB)

CMZ8GX3M1A1600C10 8GB

 

I originally bought the 4x4 kit but today I brought home 2 pcs of the 8GB sticks to upgrade with. The MB only has four DIMM slots so I took out two of the 4GB sticks and inserted two 8GB sticks in their place. So in total:

 

Slot1 8GB

Slot2 4GB

Slot3 8GB

Slot4 4GB

 

since the MB manual states:

Channel A: DDR3_2, DDR3_4

Channel B: DDR3_1, DDR3_3

 

 

With 4x4GB sticks = boots ok

With 2x8GB sticks only = boots ok

 

But with the above described 2x4GB + 2x8GB = the MB starts up but after just a few seconds it reboots, starts up a few seconds and the reboots, and so on in an endless fashion. No error beeps.

 

 

Any idea what to do?

 

 

 

heeeeeeeeeeeeeeeeeeeeeeeeeeeeeelp! :-)

sell or return one kit.

a lot of people assume they can mix kits, the compatibility chart is for 1 single kit only not even 2 of the same part#

read the links below about mixing ram, im off to a funeral for a panda ;)

Yeah, I started to understand it was a can of worms I opened. But I continued fiddling with everything and with this setup everything works perfectly:

 

Slot1 4GB

Slot2 8GB

Slot3 4GB

Slot4 8GB

 

Logical? Naaaaaahhhhhh..... Something with bus loads? Who knows....

buy a lottery ticket, you are one of the lucky few to actually make it work. i would say out of 500 threads like yours maybe 10 or 20 have been as lucky.

 

i guess the panda was just in a coma after all :):
