Difference between the E6400 & E6600

Can someone tell the difference between these two processors? I already know that E6600 and higher have 4MB of L2 Cache and the E6400 & lower have only 2MB of L2 Cache. So then is there an even bigger difference than the L2 cache? Please and thank you! :D

The extra cache doesn't matter much. The higher multiplier of the E6600 gives it a higher clock speed, and with the new batch of Allendales, the Conroes, in comparison, have more headroom for overclocking. So, if you're lucky and get an earlier E6400, then you'd probably have great headroom for oc'ing... if you get one of the recent production chips, then you're probably limited to 3.2Ghz max.

I wonder how well the newer 6420 and 6320 will oc.

Those will be Conroe cores, so I assume better than Allendales. The earlier E6400/E6300's were Conroe cores with half of their cache's disabled. The newer ones (B2 stepping?) are thought to be true Allendales, like the E4300, since they all share the same clock speed wall.
 
Yes, but the price difference between the 2 will probably be smaller than it is now... Its all up to how you plan your set up and what kind of overclock youre looking at..... if your goal is less than 3500mhz, then the E6320 is your best bang/buck, this is with the assumption that your ram/ mobo is capable of 500fsb...... The way I look at the new conroes that are comming up, you are paying for the multi, at 3500mhz, all you need is a 7x multi so paying more for 8x and up is a waste of money..... just make sure at the end of it all that its you cpu that will crap out first before the mobo/ram..... Nothing worse than having an e6300 capable of 3800mhz on a board that can only do 500fsb..... thats why you need to plan it as a whole and not just buy whatever you think is good...... ie, e6300 + P975 is the worse combo I can think of right now.... then match it with PC8800 rams......lol..
 
So then if the E6300's and E6400's only have the half the cache disabled then can't someone re enable it?

Seriously though can we?;) (we as in someone, someone as in not me, not me as in some smart shmuck. you get the idea.)

The cache is usually disabled because it doesn't work. When the CPU's are binned there is always a number that come off the line that don't work and a lot of the time it's something to do with the cache since the cache consumes a large portion of the CPU die. Sometimes they can just disable a portion of the cache and the CPU will work fine then. And no there is no way for you to re-enable the cache.
