Two bad DIMM sockets, how much of a performance hit with memory in single channel?

[James Jeakle]

I have 2 bad dimm sockets on my motherboard which only allows me to run my memory in single channel mode. Am I losing all that much performance by not having dual channel? I'm a casual gamer by the way. I would prefer not to RMA the MB as all you get from MSI is a re-manufactured board as a replacement and this one is working fine all except for the #3 and #4 dimm sockets. I may just go and get another board, I've always had good luck with Gigabyte and would look for one of theirs to replace this one in a few months.

Not sure if my specs I listed in my profile will turn up in this post so here they are:

MSI Z77A-G45 Thunderbolt
Intel i5-3350P
MSI HD7870, Dell 22" LCD
G.Skill DDR3-1600 2x4GB
Samsung 840 EVO 250 GB SSD
Seagate 1TB HDD

Swapped out the MSI MB with an ASUS Z77 board and re-ran PCMark8 benchmarks with dual channel memory and got almost exactly the same score as the MSI board in single channel mode. This is pretty much what I expected as dual channel memory only comes in to play with advanced games from what I could find searching the interwebs. On a aside I didn't have to re-install windows 8.1 as both boards used the same Intel drivers, just swapped them out and everything fired right up. Also now having to deal with the MSI RMA BS as they claim I damaged the board and want to charge me $45 to repair it. They know where they can put that $45 as I refuse to pay for it, I'll just take it back as is and use it in my Linux box.

New MB:

Asus P8Z77-V LX
