Well I'm going to try to get Mushkin 3500 Lvl 2 in three weeks. If I am unsuccessful in being able to purchase it due to demand and short supply, I was going to go with OCZ PC 4000 Gold or Corsair XMS 4000 Pro. This will be my first experience at overclocking so as a newbie I will need all the wisdom to get a successful overclock. I have an asus p4c800 e deluxe with a 2.8c processor. I read numerous websites and discovered that this processor usually tops out in the 240-245 mhz. I contacted OCZ tech support and they recommeded the PC4000 Gold. They also recommended the OCZ PC3700 Gold Rev 2. I have equipped a thermalright sp-94 with a tornado 92mm fan. I have equipped a Swiftech MCX159-P Chip Cooler for my North Bridge. I am not really concerned with price, just overall performance. If I am limited by fsb then I am starting to think the OCZ PC3700 Rev 2 Gold is the way to go. What do you recommend and why? Thanks for all your help.
