Thinking about getting some of this memory. Heres the link http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&category=44938&item=6761034326&rd=1&ssPageName=WDVW

its such a good price i was wondering if this is some shady crap or if its good quality. whats your feedback on this type of memory?

 

As far as i know Hynix are a ok make never used them b4 thou, seems like a ok price.

 

I actually use a 512 mb stick of hynix,. and it is great.. i have had no problems, games never lag *atleast not from a network problem* and i can run atleast 15 differnt programs with out it slowing down, great peice stick, i highly recommend getting it.
