AMD CPUs Current Tech Essentials

Hey nate,drop that HT down a smidgen. Your hitting that point that the chips just don't like, between 600-1000 is ideal.

Well...I'm sure I don't have as much hands on experience with 939 as you do txtmstrjoe. However the two you see linked in my sig are the only two I've had the pleasure of playing with. Here's the low down:

Both processors were overclocked in my sig rig (the only thing that has changed was RAM and GPU):

1st:
Athlon X2 3800+ Manchester (Unknown stepping)
Had the potential to reach 2.55GHz stable, and 2.94GHz suicide run. Stabily I was at 1.425v under load (1.45v idle) using the 166MHz RAM divider to make the RAM at 212.5MHz. This was with a 1GB kit of Corsair VS DDR400. This processor is still in use (starting tomorrow again, woot!) in an MSI K8N Neo4 SLI motherboard. I'm hoping she'll still reach the happy 2.55Ghz in said board with the exact same RAM kit (Thank you thlnk3r for said board!). I don't know the stepping of this processor because I lapped it before learning that steppings matter, lol. On the plus side though....it's mirror smooth! I'd also like to mention said CPU has hit a load temperature of 95*C for 10 minutes.....and she still lives! She loads at a happy 72*C at stock voltage with the Zalman in my sig rig....yes this chip runs unnaturally hot! Don't ask me why...I have no clue.

2nd:
Opteron 165 Toledo (LCBQE stepping)
Still running today. Current stable speed is 3.0GHz (333x9), and I've reached 3.27GHz on a suicide run with 1.65v. I'm using the 133MHz divider to put my RAM at 214.5MHz with my OCZ DDR500. With the Corsair Value RAM, I had to run the 100MHz divider to put the RAM at DDR333 speeds (212.5Mhz was the Corsair's max). This is by far my favorite of all 939 processors that I've ever even heard about. I'm at 3.0GHz (67% overclock) with only 1.375v under load (1.40v ish idle). That's barely above stock volts!!! My temperatures suck royally as of right now because my case is WAY too tight for the Zalman cooler....so the hot air pretty much just hangs out inside. I load at 66*C under a full Orthos priority 9 load. Just 1*C above thermal spec, I'm happy enough with that. I've had this processor up to 78*C on a suicide run...just for fun. These chips can take more of a beating than the 55*C fairy tale will have you believe.

3rd????
I've got another Opteron coming soon. Its supposed to be a naked Opty 148. We'll see how she does....probably on the MSI board since my Zalman more than likely won't mount to a naked chip. I won't know the stepping info on it however...because its naked. The original owner stated he's hit 2.8 with it....we'll just see about that!

Out of that list...I'd have to say that the X2 3800 was more fun to overclock with however. It just seemed more of a challenge to get that sucker up in the MHz. But boy it sure was a happy moment for me when I opened my Opteron 165 up, popped her in, put FSB to 333 and I was immediately at 3.0GHz and booting Windows! That was a happy day! I still can't believe I've almost had this rig for a year now!

And finally......
SOCKET 939 STILL LIVES ON!!! ITS NOT DEAD SUCKAS!! JUST SEE MY LINKS IN MY SIG!!!

Congratulations on your sweet overclock txtmstrjoe.

Unfortunately, my Opteron seems to return back higher than expected temperatures as well. Granted my case cooling absolutely sucks (no pun intended ), but my temperatures should be nowhere NEAR 66*C under load at only 1.375v. Go figure, we got ourselves a couple of hot overclockers (pun intended this time ). This is why the hot temperatures don't bother me so much...I know that there's NO WAY my chip is actually running at 66*C, I believe it to be a whacked out thermal sensor. Just my conspiracy theory on these boobterons!

wish I could run the Vcore you do pioneer. I will continue to try and get the perfect settings=) this RAM of mine is giving me a headache thou
