G.Skill, Kingston has gone downhill in the last 10 years (G.Skill, Geil, Corsair, and Mushkin are better and usually cheaper). I have had no issues using G.Skill in any of my AMD builds (or intel builds for that matter). The only issue I've ever had with G.Skill has been the height of their heatsinks (touching my HSF).
Thanks IH8U - I have enough room for the heatsinks - so not an issue.
Appreciate the feedback.
