I wanted to put together some frame times for those thinking of going the G34 route. These are all from the same P2689 unit. Cores are at 1.8 GHz.

-smp 48 - 8:08/frame
-smp 32 - 12:12/frame
-smp 24 - 16:01/frame
-smp 16 - 23:40/frame

Not quite linear, but at least close.
 
That is about as close as it gets to linear... 97%+ scaling from 16 to 48 cores. Just like I have seen.

Also for those wondering, MHz also scales fairly linearly too.
 
Nice. What would be the projected PPD with a 4P build using the 2.5ghz 6180 dodeca's?

look up sfield's numbers. hes currently running a quad socket 2.5Ghz system. i think in windows he was doing 250-275k PPD, in linux hes probably some where in the 350-400k PPD range.
 
2.5ghz running memory at 6-7-5-20-1T, TPF ~5:43 with the 2686 below.
2.6ghz is about ~5:25 with a 6901.

It should be possible to run this memory at 5-7-5-20-1T, but I haven't gotten around to troubleshooting why the system doesn't allow that (not likely for 1-2 weeks at least). I tested the modules successfully in a SR-2 system at 5-7-5-20-1T up to DDR3-1440.

[02:27:22] Project: 2686 (Run 4, Clone 8, Gen 108)

I'll do the conversion for the mortals:

5:43 = 450,600 ppd
5:25 = 488,500ppd.

Oh, that needs a smiley: :eek:
 
Musky, you should be able to tweak that ppd/watt higher still. Although you can't raise the multiplier on Retail chips, you can still undervolt them and the guys at AMDZone are running theirs below 1v for significant power and temperature savings.

If you want to tweak further, you can follow Patriot as he experiments with Blood Mag...err... SPD hacking.

WOW!!! That definitely deserves a smiley :D
That's 610-650 ppd/watt!!! :eek:
Now with those times can he do 2 bigadv in a day?

Yes. At 7min you can do it with uploading. Of course 2684's still wreck these things.
 
Cores at 1.9 and 4 channel RAM SMP 36 (maps to 32?)

3x 6168 CPU on 2686 w/kraken 10:53 tpf for 170k

Same tpf on 6901. 4th CPU coming on Wednesday, but will be out of town for some time before I can install it...

738W @ 2.5ghz running memory at 6-7-5-20-1T, TPF ~5:43 with the 2686 referenced above.
750W @ 2.6ghz, 6901.

Have only just started playing with reducing vcore.

"thud"

....the sound of Musky throwing his 1.8ghz CPUs in the trash and firing up newegg.com

on a serious note, musky, what does your PPD per watt look like.

Also, put this info in our database you n00bs!

My 1.8 quads were around 430w for reference.
The 2.2 quads are well over 500w.

Also current TPF for the 2.2's on a 2686 (still no 6901's) are 6:37... good for 360K ppd. The 2684's were still giving about 205K ppd.

At ~$1500/processor, I don't think so...

The one running on an 80+ Silver PSU pulls 447W, and I am sure the one on an 80+ Gold PU is pulling less that that. They both can clear 280K ppd, for somewhere north of 625 ppd/W. I am quite please with that. For comparison, my SR-2s do around 335 ppd/W.

The "real" upgrade path for me is when BD releases and these higher end MC dodecas start dropping in price. I doubt I will see a BD chip for quite a while due to the cost.
 
what happened to the old excel sheet where every body used to enter their tpf's before?

We had data integrity issues. Haitch has been building a benchmark application to automate everything and push directly to a MySQL database. Still not fancy, but useful. I think all of the DP/4P G34 systems are running Linux. Linux FAHBench is still a work in progress at this point.

Get FAHBench

Since I know you are looking for G34 numbers see my post here: http://hardforum.com/showpost.php?p=1037246992&postcount=18
 
Ok, so where does a guy get 4 12-core processors at a reasonable price.
My deal just fell through the floor.

I'm sitting here with everything but the cpu's to bring up another 4p board.
And only ~ 2K to gitterdone.

:(
 
It looks like you could get four Opteron 6172 on ebay for $2250. That would be 48x2.1ghz = 100.8ghz. You wouldn't want to run at under 100ghz now would you?:p
 
"Reasonable" dodeca cores are tough to come by TBH. Not exactly a mass appeal product like Intel Core CPUs. Tried selling my dodecas a few weeks back in 2P configurations without much luck. Not a huge market out there.

Crap! That's just close enough to pull the trigger. Only problem is that he's only selling 1.
Next closet is $2400. Just out of reach. And that one only has 2.

Still have them?
I could grab 2 6172's off ebay, mate them to the 2 in the 2p I have, and buy 2 lower models for the 2p. Failing that, maybe I'll pick up a couple 6136's....

Nice! I'm glad the link I posted was able to help someone, looking at g34 procs every other day in a desperate bid to find a second extra special chip can get a bit depressing...
