cml8gx3m2a1600c9w will it work on g41m combo

No for Cmz8gx3m2x1600c7r; maybe for cmv8gx3m2a1600c11 if it still is low density. An issue is that manufacturers switched to high density because it costs less to use 8 ICs instead of 16. A good example is https://www.newegg.com/Product/Product.aspx?Item=N82E16820231314 where you can clearly see on the package that it's compatible with socket 1155 (and your motherboard); the kit that's delivered looks identical, but it's high density. The same kit built in 2011 was low density. Guess how I found out.

Contact Corsair support to make absolutely sure they are low density (8 ICs on each side for a total of 16) or that you can return them if they don't work (probably at your expense).
