I was working on my factory made computer and tried to flash my bios. lets just say something went wrong and now my computer wont come on. So i ordered a Gigabyte MA78GM-US2H MoBo with AMD Athlon X2 Dual Core 7850, 2.80GHz (black edition). I am really wanting to use some of my old parts. I currently have 2-2gb 667mhz double sided OCZ chips, and 2-1gb 800mhz single sided chips, I have researched alot and found out that without taking the dimm/simm thing into consideration, it would be ok to run these in dual channel mode as long as i put the two matching chips in the correct ram banks (example 2 2gb in 1 and 3, and 2 1 gb in bank 2 and 4) but does it matter that 2 are double sided and 2 are single sided, and also i know they are all gonna run at 667mhz, im ok with that, just as long as its stable, can someone please shed some light on this situation?
