Tommorow I'm ordering parts to build my first computer (http://forum.oc-forums.com/vb/showthread.php?s=&threadid=106074). I was planning on using oc'd ddr ram (samsung or corsair), but then my friend told me that he has 512 mb of pc800 rdram on his old dell computer that I can have for free. If I go with that I figure i'll get a TH7-II mobo with a 1.8a p4. I was wondering what brand of ram dell uses, and if it'll be good to oc my system with. Going with the free rdram would save me $200 dollars compared to the ddr I was going to buy, but if it limits my system alot, then it might just be worth buying some ram of my own. Any suggestions?
