i usually don't go with SONY products either, mainly because they're overpriced.
OCZ, PQI, Ultra are what i suggest for 939 overclockers...TCCD is the BEST right now hands down and i have seen memory 290mhz b4.
If you don't overclock it then i suggest Mushkin, Kingston, Patriot...alot of brands are very good stock. Don't get GEIL though...i have had BAD sticks b4 with them. They couldn't run stock...had to underclock them and loosen timings just to get them to boot. Corsair is great for overclocking, the only reason i dont suggest them is because they are outperformed tremendously by TCCD sticks on 939 chips most of the time. Great for almost any other though.
