Hi,
I recently purchased an ASRock H87 Pro4 motherboard and 2x4GB DDR3 RAM (8GB total).
No matter which way I put the RAM sticks in, it simply will not have them as dual channel. It says that Channel B failed the CPU memory test. I have tried this with having cards in A1&B1, or A2&B2 (the 'paired' combinations), with each card in each slot. It is not a problem with the RAM. If I place them directly next to each other (A1 & A2) the machine runs with full 8GB RAM, just on single channel.
The only thing I can conclude is that I have purchased a defective motherboard - does anyone have any other theories or tests to suggest before I claim for a refund?
Additionally, how much slower is 8GB running in single channel than dual channel? Laziness instinct after going through the hassle of setting it up and all.. if it's only a minor difference I'll make do, but if it is a considerable difference I'll just have to try again..
