I dunno if you can say it's a good company or not, but I've read a few reviews for the Kingmax PC4000 ram and it appears to be decent. Check out this review:
Kingmax is not good man, my mate bought some of this ram and his pc kept rebooting so he got his stick replace still did it, put my crucial in and it worked like a dream!
normal kingmax is used in premade pcs so i dont kno if good for OC, but the HARDCORE stuff appears to b quite good personally id stick with trusted ocing brands till this stuff gets more reviews
