First and foremost, I'd like to thank Dave for this awesome chip.

Secondly, I'd like anyone who believes in some form of a deity to pray for Dave, and his family, and for his father. No specifics--just pray.

You don't have to. I did. Just suggesting you all do, as well.

Now, onto the reason you came to this thread.

I just got my X2 3800+ from Dave.

Currently running 2.6Ghz @ STOCK.
And SPi1M stable (I'm going to find where it is no longer SPi 1M stable, then back down from there; then I'll start running prime)

Note, this is on STOCK cooling with the STOCK HSF and STOCK goop.

I won't be putting it under water 'till I get my mounting kit for my Maze4, so I'll have a few days to tinker with it. This was kind've an idea to experiment to see how this chip could do on air, how well it could do on water and an exotic thermal grease, and see if the watercooling setup/extra costs were justified.

So, a summary:
Current Stats Below!
Currently Priming @ 2.7 1.43v (Note: Just failed on Core0 after 5 minutes. Going to up to 1.45v Need to find my DMM to get exact volts)
CPU temp readings are 46C idle.
CPU temp readings are around 60C when under extended load.
(For reference, on my water setup I ran @ 29-31C idle; vs 44C idle here. So in IDLE temps, I'm getting an ~12C drop! Load on my water setup was 37C--here it's around 60C--23C!.)

I'm going to lay off for now until I get my water setup running. Someone @ XS said with 1.5v they managed to hit 2.85Ghz, on AIR [Same stepping]. I don't feel comfortable running 1.5v, especially with these temps.

I figure I might have a slight chance of 3Ghz if I pump ~1.525/1.5 into it with water.

Update again
I took the volage down to 'auto' (Which I believe defaults to 1.325 on my board, which undervolts a bit), a measurement gives me 1.31v
Not bad.

What stunned me was where the overclock went.
With those volts, I went to 2.5 no problem, primed for 2 hours.. just upped another 50Mhz. If it's still stable in the morning, I'll up it another 50. This'll be interesting to see where it peaks out as such a low voltage.

Side note, running Priority 9; so I'm assuming that it will be catching errors FASTER (hence going up to 2.55 after 2.5 hours @ 2.50)

Ah, good point.
LDBHE 0602 XPMW
Don't have the last line memorized, but I do remember that the wafer is A600. I think.

nice, now the only thing you have to test is prime95 stable....my x2 3800+ needs 1.4V at 2600Mhz to get 24hours stable in prime...

As you might understand (see sig), I won't be praying for Dave. Why would we have to pray for Dave? Is something wrong?

(By the way, I'm not saying I don't feel for the guy.)

Yeah, I understand. Hence the 'anyone in who believes in some form of a deity'. =P

I guess I can post this here, because he e-mailed it to virtually everyone on his mailing list.

Actually, let me throw it into another thread, don't want to complicate things here.

Edit, here's the thread Link
--Trevor

CPU updates
Couldn't prime @ 2.75; temps are too high.
Brought it down to 2.65 primed all night at 1.45 volts (Was going to bring it back down to stock, but I was way too tired for that.

Currently playing a round of games, because I'll be gone all night and I can prime then.
Again, this is only on air, and the temps are absurd--given a little water, I'm sure this will cool down a bit ;)

Very kind of you. And I must say, nice proc :D.

Yeah. Took the voltage down a bit ( to 1.450; though DFI cranks it down to 1.43. <---Real voltage)
Priming right now.
Also brought my memory up to speed (Running 1:1, which is nice)

Just can't wait for this bloody mounting kit to get here o_o

Ah well.

At least I can perfect my build.
