This might explain why pc didn't start up atall if I placed buffalo's dual channel sticks in A2 and B2 and left other slots empty. I did read than if you are using somekind specific cpu (mine is intel i5-760) the ram has to be put in A1 and B1 slots. Is it motherboard, Ram or just bios settings. I still can't figure out what is to blame though. I know you shouldn't mix dual channel and normal but this was more of a experiment. Now bios detects 4 gigs only but I have no idea which sticks are actually in use. I left dual channels as they are and added APACER's sticks in the mix. Then I decided to go bit crazy on these sticks and put them all in. I tried put these in A1 and B1 slots and bios still only detected 2 gigs as ram. So I bought pair new ones.īuffalo 4GB KIT DDR3 1333 RETAIL which is 2 x 2gig dual channel. So they should work which ever slot I put them right? Well bios detects only 2 gigs.Īt first I thought it was just something wrong with the ram.

Note these ram sticks are universal not dual channel. So I had 2 x 2 gigs ram installed (APACER DDR3-1333 2G DIMM CL9 128*8 ROHS) The mother board has 4 ram slots so from left to right it should be something like this.īlack, light blue, space, black and light blue.īy the manual than came with the motherboard those slots are named as following: I'm having bit of a bizarre problem with bios not detecting all my ram. But after I tried to install a third one it always throws me a blue screen of death. I just put the 2 RAM in, and after a few tries it always worked. I'm not sure should I post this on Ram or motherboard thread but I'm sure admin will take care of that if this is posted in wrong place. I have always seen that the motherboard RAM slots are colored in pairs, but never knew what it meant.
