anonymous88, I think what the problem you're having is a misunderstanding. ram doesn't have a "set" speed per say, and you can't run ram independently on the p965 boards. In the main 266 strap, you have 1:1, 4:5, and 2:3. These are better represented as 533mhz, 667, and 800, while fsb is at 266. Thus, when you scale up fsb, if you keep the highest setting, it's actually going to scale as well. The newer bios revisions do indeed have this value scale up, which you can probably notice.

Now, that said, you being able to run your e6300 at 3.3ghz means your fsb is at 471, which is quite respectable already. Running 1:1, like you have, you get also 471 ram (942).

In the p5b settings, you do have further memory speed options than the three listed above, but those run on a lower strap, which means that it will excessively overclock the motherboard. That's why if perhaps you chose one of those settings, when you tried to overclock past stock, it didn't work.

So that said, since you have a e6300, you're going to need high fsb to run it up to speed. That said, your only option would be 1:1. The next level would be 4:5, but at 471fsb, that'd equate to ram running at 589 or 1177. Now, with a little more voltage, there's a good chance you can get your ram to run at that speed. However, running 4:5 is much harder on most p965 boards, which means that at that high of an fsb (471), chances are 4:5 won't work anymore, leaving you with only 1:1.

So at this point, you should just work on seeing where you can bring fsb. And then maybe work on timings.

To be able to run your ram at rated speeds of 1066, while using 1:1, you'd need fsb at 533, which is a bit of a challenge for most boards. That said, you'd probably be only looking at the 6x multiplier if you did so, which would mean 6x533=3200.

Just find you max with cas4 and you should be happy
