I found a good deal on the 8 GB Value Select Coasair ram like you mentioned for my Dell XPS 410/9200. I researched more and it appears I could upgrade the Intel Duo Core E6300 in rig to a E8400, so I put a bid on e-bay and won a new one cheap ( alot of use ones available ). All indications say I should not have problems installing and with out changing anything in the bios. I don’t think I will attempt any overclocking. I am fully updated with chipset, bios versions as well. I have a new tube of silver thermal paste with cpu cleaning kit. My understanding the cpu should run cool, but If works, I will be testing mem and cpu hard. My exsisting cpu fan and cooling fins should be ok. I may go as far, depending on temperatures and install a dual fan 82mm kit in rear of tower as I saw it done on YouTube on the 410, I may purchase anyway just to be safe. I am hopeing not to get into any water cooling or expensive cpu cooling device. I will keep you informed, as the ram should be coming first and I will install first b4 cpu. Wish me luck.
