I just bought 8gb of new ram which is this one here http://www.amazon.com/gp/product/B004QBUL1C/ref=oh_deta... coupled with a MSI 870-G45 motherboard (http://us.msi.com/product/mb/870-G45.html) and it seems that ram slots 1&3 won't work. I've checked my ram with memtest to make sure they were good and I got no errors so I was forced to put the ram In slots 2&4 which in this case the computer did turn on but being single channel instead of dual. I tried resetting the cmos battery also which didn't help. I'm assuming my ram slots are bad and the only thing I can really do is replace the motherboard which I'm not at the liberty of doing right now
The real question is, should I just return the 8gb's of ram and get my money back and just put back in my old 4gb stick? because I cant imagine there would be a worthy difference of 4gb, especially if its single channel and is dual channel really needed? preferably gaming wise.
