..I have recently purchased a brand new boxed Core 2 Duo E6600 2.40Ghz/1066/4Mb SL9ZL (Package date: 05/15/07), am I amongst the "earlier" Conroe family of Core 2 Duo procesors? - I am currently experimenting problems in slightly overclocking such CPU, but cannot go beyond 2.51Ghz, using a ASUS P5G41T-M LX mobo along side with high performance G.Skill Ripjaws X PC10666 (1333Mhz) RAM. I am currently using my new system with stock defaults, and my RAM "down-clocked" to 1.066Mhz instead of 1.333Mhz.
At some point, I would like to "pump" the processors speed to at least 2.80Ghz (ocasionally), with a 4 phase design mobo with overclocking capabilities to 1.333Mhz MAX (CPU & RAM), and of course, cooled by a Coolermaster Hyper 212 Plus and sufficient ventilation in my new Thermaltake mid-tower case, I shouldn't have any problems.
Whats holding me back? - The CPU perhaps, which seems to be "locked" from X6 to X9 (multiplier), according to the mobo's year 2011 BIOS, I wouldn't think the RAM is to blame, baring in mind that it's stock speed is 1.333Mhz, and yet, can be slightly overclocked.
you shouldnt need to overclock ram. set the ram no higher than its rated speed. These g41 motherboards are poor overclockers. You really shouldnt waste your time on core 2 duo's now. If buying a new cheaper dual core setup, always go AMD. I got my core 2 duo e6600 over 4 years ago.........
