This would be a first, no? :D Since it is, it's time for the story of how this came to be, with an excessive number of smilies. :cool:

Before I get into it, here is the final result of my playtime for those who are lazy and don't want to read the whole post. :D
http://valid.x86-secret.com/show_oc.php?id=266059


The chip arrives, and is passed onto the quality control department. It passes! :D




A closer look at the processor itself. Heatspreader quality is rather poor, nothing that a few passes over some 600 grit can't fix ;)




First up was some testing under a TDX. A pretty hard limit for stability at 3.36GHz was found with just a bit of grumbling at the temperatures :p



With the same ambient temps (like 63ºF :cool: ), 3.65Ghz was observed with 1.525v. More voltage was worse. I suppose heat was getting to it, so I opened a window. After dropping the load temp to 40ºC, I went for another maximum suicide run on water, and turned up with 3741MHz, which tied SillySider03 for the 5000+ Black Edition WR yesterday. I wasn't satisfied with simply tying with the fastest speed. All out is what I wanted, so all out is what I did.

Well, as all out as you can go with a 65nm AMD chip that is. Knowing very well that battling the cold bug with dry ice was going to be a very fun activity, I picked up some dry ice on the way home from work today.


(yeah, I know. Blocks of ice are lame to work with)


And set up the alu tube I have. :D




First thing I did was find the minimum temperature the chip could run at, which ended up being "238ºC" as reported by smartguardian, which is really -18ºC, but being a Brisbane, who knows how accurate the temperature sensors are. :rolleyes:

After a few practice runs, I managed to get this validated:
3933.83MHz

Not a bad start, and exceptionally close to my goal for about an hour's worth of work. I'm getting hungry and need some dinner at this point, but quitting is for losers, so onward I push.

Pushing the temp down a few degrees to -12ºC and the voltage up to 1.6v + 103% for 1.648v (for those not familiar with the DFI NF590 SLI motherboard, it offers an INSANE number of vcore options), I could almost touch the magical number :D
3990.39MHz

Those last 10MHz were the most difficult 10MHz ever. After trying every voltage combination from 1.6v+102% to 1.6v+106% in 0.05 to 0.1% increments, and a few runs at slightly different temps with a few of the better voltages, I finally managed to break into the 4GHz region and stay stable enough to take a screenshot of it :D

4009.86MHz :D:D:D




The story ends here... for now ;)

Hey now... He can't celebrate with a $10 box of wine. Spend like $15 and get a bottle and pop it open....lol

Congrats on a nice OC.

congrats on a record for a suicide screenshot.

But I've never been too impressed with those.

I'm far more impressed by a 24 hour Orthos / Prime stable system!

Even a SuperPi 2M run would be nice.

SO what did you use? ice + alcohol ? or is that dry ice?

SHOW THE MAN SOME RESPECT! Read the freaking thread.

Awsome work man!

now lets see some max semi stable benchmarking!

So a member of this community breaks a world record by over 200MHz and you're not impressed? Wow is all I can say to that, because otherwise I'll spew troll filth from my mouth about how amazingly unbelievable that comment is.

And seriously, fucking read the article. He used dry ice. It's not like he typed a lot. I can only wonder what would happen had he not included images in the thread. :rolleyes:

nope....im the one that OCs his rig lol.....but is he spots this....he will try to make me take his X2 3800 as far as it can go.......(to top it off....hes on a stock cooler :eek:)....

I cant wait until we see some mass OC to the new AMD chip :)

Is their anything you can't do!?

1. Awesome kitten/QC
2. Awesome OC

You indeed are the man! Congrats!

Extremely nice, my old 90nm x2 4000+ only goes to 3.0. on air. And im glad to see i have the same mobo+memory as you do.

I would like to point out though that while your chip is doing 4.0ghz x2, your bus speed is still low, and your ht link is low. Next i would try getting like 3.8ghz with a 280bus and 1400 ht, then that would be a blazing fast computer. I do 2.8, 280, 1400, which is pretty damn fast.
