Yes E6X20 CPUs have all double cache but they have the lowest OCing potential. Ofcourse cache has a bigger role than the OCing potential but each person decides for his own.

I don't know where you got your sources from, because I've got one E6420 here right now, on low-cfm aircooling (sub45cfm), running 3.4ghz, 1.3875V.

E6400 vs. E6420 - E6420 wins IMO.

Reason: More cache, better steppings since it's released months after the E6400, which results in cooler temps in most case.

I've experienced the E6320 overclock and it's superb. 2.9Ghz - 1.35vcore - 31C ambient - 29C idle - 50Cload.

My E6400 at 2.9Ghz - 1.22vcore - 29C ambient - 41C idle - 56C~57C load - LESS cache! ._.

The temps above are from stock HSF with line method AS5 applied.

Cache is not more important than OC potential.....

When C2Ds were first released there were several tests done that showed an E6300 vs. E6600 overclocked to the same speed were within a 1.5 seconds of each other in Super Pi.

OC potential is WAY more important than cache size.

Get the E6400 over the E6420

Common sense is so hard to find....what you guys arguing that the cache is more important than OCing potential are saying is that a faster E6400 at say 3.4GHz is worse than an E6600 at say 3GHz cause the cache is more......um ok

The only real apps that cache matters on are extracting RAR and ZIP or .tar.bz archives and frankly, 2MB L2 is more than enough for now LOL....

>> The newest stepping is used by the 6300 which is L2. the old 6300 and the 6320 have b2 stepping.

If you want you could check here. http://processorfinder.intel.com/Lis...Spec=&OrdCode=
You will see that the oldest model 6300 has both Tdiode enabled and 22W Extended Halt Power. the newest 6300 model has only 12W Extended Halt Power and 6320 lacks both Tdiode and Extended Halt Power.

Though so too until recently a Overclocking.net member told me I was wrong and explained to me why. So what is right in the end?

-Edit-
Damn double post.

If anyone's telling you that the E6420 OCs worse than the E6400, I can tell you right now that I owned an E6400, and I can only get it to be stable at 3.2ghz, compared to the 3.4ghz I could get on the E6420 on a LOWER vCore.

I swapped out the CPUs, and thats the only thing I did. Not that I wasn't happy with the 3.2ghz, but I was attracted to the extra 2mb cache, but the higher overclock isn't a bad thing.....

The E6400 was an L629B, and the E6420 was an L652B. I'd say they're similar enough.
