4GHz on AMD's 65nm process!

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
http://www.eclipseoc.com/image/cpu/a...ch/4009.86.png

The chip arrives, and is passed onto the quality control department. It passes! :lol2:

http://www.eclipseoc.com/image/cpu/a...k/approved.jpg

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

http://www.eclipseoc.com/image/cpu/a...%20black/4.jpg

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:

http://www.eclipseoc.com/image/cpu/a...h/3361-61m.png

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.

http://www.eclipseoc.com/image/cpu/a.../bench/di3.jpg
(yeah, I know. Blocks of ice are lame to work with)

And set up the alu tube I have. :D

http://www.eclipseoc.com/image/cpu/a.../bench/di1.jpg
http://www.eclipseoc.com/image/cpu/a.../bench/di2.jpg

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

http://www.eclipseoc.com/image/cpu/a...ch/4009.86.png

The story ends here... for now ;)

Congrats on the new 5000+ WR and being the first AMD 65nm to 4GHz! :D You da man, sir.

:woot: congrats Mark!! That's a huge OC and battling the cold bug with DI is one hell of a task? Isopropyl alcohol I'm seeing there?

Anyways if your problem is that your temps are too low, one would think you'd be able to pull off similar speeds under a load...say a 1M? :cool:

perhaps, but it's certainly not as difficult as it once was if I can do in one night with the first chip I tried. :D

it is indeed isoprpyl. i have a bunch of it laying around so i use it instead of acetone.
for 1M, i didn't really get around to seeing what this guy can do while benching. i need to sort out the memory controller :D and then tune it to try to overcome the inherent slowness of brisbane first :rolleyes:

That's AMAZING !
It is like a Ferrari F430 on a speed of 499KMph !
At least you could make some benchmark on 3.8-3.9Ghz ?
Any chance?

Good luck for your Super OC :)

Congrats man ! 4GHz on and AMD ... OMG! Although I prefer 5700MHz 3D Mark benchable (you all know what I'm talkin' about :D) ...
11-10-2007, 08:33 AM
tsuehpsyde

The thing to note here is that a few people have done 4GHz on AMD before, but Mark is the first to do it on 65nm. I mean heck, there are 6400+'s that have done 4200MHz, but those are 90nm. :) Seeing this at 65nm is just awesome to say the least. Plus I mean, how many of us can say we're part of the 4GHz AMD club? :lol:

5000+ black edition is a new Brisbane revision G2, it is even more overclockable than Windsor F3

ozzimark, I think you kitten liked strange black box :)

further is always possible. it's just how difficult will it be to get another 10mhz? :p

haha, yeah. next time i'll spend a little time on trying to maintain a temp under load and get some benches. ;)

i know how that is lol 2.59ghz on my newcastle and she wont budge another 10mhz :( not the chips fault though my mobo is great as far as volts go but has no bus locks so its kinda hard to push :rofl:

Very impressive, I like your skill with the temperature manipulation, seems like the optimal temp is somewhere in between chilled water and DI.

Wait! Chillers get that cold easily and would be ideal for this chip by the looks of it.

indeed, a chiller would be perfect, and would probably hold a load a lot better than my dice pot. but i have the pot for now, and i can't justify buying more cooling just yet. more exciting hardware comes first! :D

Ah, I was thinking more along the lines of water freezing at 0C, but I forgot about adding antifreeze.

Looking great Mark. Hope to see higher from you soon. Have you tried using a little water in the pot to build up an ice layer? Should make temps more controlable.

That pot is more than enough for 4.7 on a B3 kents on dry ice. :up:

Congratulations on the achievement. May i suggest that next time you stick some K-Type thermal probe on the pot and strap it down with some plastic tape, you will be able to control your temperature much easier + we will see the deltaT between the pot and CPU.

Congrats once again!
11-12-2007, 12:04 PM
ozzimark

problem with doing that is that the temperature of the cpu is what matters to me, not the temp of the bottom of the base. changing the voltage changes the difference between the two, which would make it a pretty useless measurement for me when fighting the cold bug ;)
