Have the bolt in an MSI GE installed 60 245 and i760 so it upgraded to 8GB. Has, although I am a layman, just five minutes lasted. RAM was immediately recognized under Windows 7 and CPU-Z and is working properly. According to Windows 7 mini-application my RAM utilization was normal Win7 operating at about 40%. Now with 8GB at about 20%. That just in case anyone considering upgrading to 8GB. Am fully satisfied, and also even cheaper than Value-Ram. Oh yes, on my bars are installed Nanya chips, which were also in my laptop.
