I was wondering about my motherboard today, and it says it supports DDR2 1333. Yet, I have never seen DDR2 run that fast ever. Is there any DDR2 sticks out there that would support this crazy speed?

Ballistix are known to hit around there.

Mine can do 1300 cas 5 with 2.4v which is not recommend for long runs.

These are the fastest stock DDR2s I've seen so far.

Mine could probably get close to that. I can do 1200 easy 6-6-6-18 2.1v. I just don't want to go over 2.1v. Ive seen sticks that can be overclocked to 2.2/2.3v without losing the warranty

Yeah, I was wondering that, I guess I have seen over 1333, but those were suicide runs. It's just good to know that my motherboard should be super stable with RAM.

There is not DDR2 1333 and no one here posting has done?

If you had to RMA short of you telling them how exactly would they know voltage?

Edit: JEDEC standards say DDR2 must be able to handle 2.3v without damage?

Got a link to those standards?

According to JEDEC the maximum recommended voltage is 1.9 volts and should be considered the absolute maximum when memory stability is an issue (such as in servers or other mission critical devices). In addition, JEDEC states that memory modules must withstand up to 2.3 volts before incurring permanent damage (although they may not actually function correctly at that level).

Link to wiki.

If this is not enough you can join JEDEC and read incredibly badly written technical papers as I have. DDR2 actually only goes up to PC6400 but they did make an addendum that does have PC8500.

Is this enough? If not just ask as I can flood you with info?
