if they dont display it, its hard to tell. you have to look on the surface of the chip. e6 have been having some problems overclocking.

What are the differences between the 2?

I just finished doing some pretty intensive research on the X2 3800+

Very interesting last couple hours it was...

There are actually two different X2 3800+ out there.

One is an E4 Manchester.
The other is a less seen E6 Toledo with half the cache disabled. Most likely they are 4400+ that had half the cache fail, & were down-binned.

If you look on AMD' site, you will see that for each Manchester X2, there are two versions, the E4, & the E6.

Now more than likely, the E6 4200+ is a cache-failed 4400+, & the E6 4600+ is a cache-failed 4800+.

That why the E6 3800+ is so interesting to me.
As of the present, there is no 4000+, so the E6 3800+ has to be a cache-failed 4400+. The only downside of that is that is may also be a speed-failed 4400+, which isn't so good for us OCers.

However, it seems both E4 & E6 3800+ are hitting very nice OCs.

I think the OCing potential is higher with the E6 3800+ myself, since i'm assuming they were designed to be 4400+, which should mean a slightly higher OC.

Either way though, both E4 & E6 3800+ seem to hit 2.4GHz at the lowest, which means a free upgrade to 4600+ 🙂

Here's the links to some great info on the X2s & the different revisions:

On AMD's compare site, select X2, & more details will appear -

Heh, I dont think it makes a difference other than the fact that they're different batches. There are E4 4600+ and 4200+ so both "core revisions" are have the same clockspeed targets.
