I've got my DS3 mobo, awesome G. Skill 800 mhz RAM...about to pull the trigger on the E6600 from the Egg when I see a thread saying that the newer E6420 overclocks better than the older E6600 batches.

Are there any benchies to prove this? Would anyone recommned one over the other for OC? I definitely want to get to at least 3.2 ghz. The $36 price difference doesn't make much difference to me - I just want the best performance and longest lifespan (won't upgrade for a long time).

From what i've heard, 6420 overclocks better than 6600. When you overclock e6420 to say 3.28GHZ (410fsb), the memory would perform better. Due to the strap changes in the north bridge at 411~mhz, no memory will performance lost. Your fsb would be 410, your Ram would be overclocked to 820mhz. This overclocking should be easily be achievable and yields higher performance than e6600 clocked at 3.285ghz ( 365mhz fsb)

I don't think thats totally true. There's a reason why the 6600 may have problems when you look at the 6400 or 6420. It's simply the default multiplier, which causes a different scaling of the NB chip. Of course the data they provide is more out of my league of understanding exactly whats going on.

By disabling the speed step, you should be able to choose the lower multi ( x8 ). This should make it run the same way the 6400 or 6420 with its default multi which is x8.

All I can say is...

If you want to save money, just get the 6420.

If you have the cash, and 36-37 bucks is nothing, buy the 6600 then.

For me, I don't think its really the CPU is going to have that much of a problem, its more of the hardware trying to run it. But then not all CPU's of the same family will be equal. Like they say its like the lottery, some will OC better then the other. With that said, you can't just pick out a CPU like your at a grocery store, and tap/shake on the fruit to find out what is fresher. :lol: 

Over clocking to me, is the just a way of getting low or mid range products that cost less, and turn it in to a high end performing machine, without having to spend allot.

Its not just about getting the best performance you can, but what you can afford. Other then that, we prolly all be running rigs that cost 5 grand. :wink:

Generally... the earlier the stepping, the more overclockability it has.

I finally decided to just bite the bullet and get the 6600. Because even if it OC like crap, I still have a good processor. Thanks guys SO MUCH for all your help!!

can't you wait 1 more month? The price will drop a lot. You could get Q6600 for the same price as if you get E6600 right now. Even if it doesn't OC as well as E6600, it will still out perform it at the same price. Its essentially 2 E6600 glued together.

You mean two more months and no, I can't wait. Vet school trumps computer building ;)

I rounded down the numbers for you... It's more like 1 1/2 month. It always makes me feel better and makes time pass by faster when i round the numbers down.
