Folding@home news 11th -18th April 2013

I tried uping my 4P baseclock to 235 and promptly lost an 8104 @ 85% - that'll teach me.

Back down to 230MHz now - it seems pretty happy at that - got through an 8101 with no problems .

Edit: Looks like I spoke too soon - just lost another 8104 :(

Edit Edit: after further investigation - it looks like it was a fault with the Work Unit and not an unstable machine....it's just picked up another 8104 so will let that one run and see how it fairs

The one we are talking about now are quad 12 core Opterons (48core total)

But we run a mixture of:
Quad 12 Core Magny-Cours opterons (loudbob, Baba & myself)
Quad 16 Core Interlagos (me)
Quad 8 Core/16 Thread E5-4650 (BaBa and soon to be loudbob)
 
What kind of PPD are each of those doing?

I am familiar with the 12C 6166 and above Opterons.
The 16 core ones are 6300 series? Hoe good does it fold and compared to the dual Xeon system?
 
PPD depends on the work unit. And in most cases different cpus will perform better on different WU's


My 16 core is 6200 a 6272. They require higher overclocks, but are capable of them, the 6300 are a bit better again.

Comparing them to a dual xeon system depends a lot on what chips you are comparing but a quad 12 core or better opteron box will always score better than a dual Xeon box and the initial outlay is less.

Now nothing really competes with a QUAD xeon e5 box but they are pretty expensive in comparison.

The 12 core magny-cours (61xx) chips are actually more efficient at folding, you need to push a 16 core 62xx to pretty high speeds to match and then beat one. On the flip side you can't overclock the 61xx's as high.

The Intel E5 Xeons are much more expensive to buy, but much lower power usage over the long term and higher performing than all the Opterons even highly clocked 63xx (although I think its a close run thing)

Basically, with an overclocked 6166HE rig @ 2.3Ghz or a stock 6176SE @ 2.3Ghz you can expect estimated output of:

8101 @ 340K PPD
8102/3/4/5 @ 540K PPD

A 3.1Ghz overclocked 62xx will do another 25% on top or 675K PPD and more if you are brave enough to go higher (up to 3.6Ghz)

A similarly clocked 63xx will do another 10-12% on top so 750K PPD or so

A similaryl clocked E5-4650 will do another 36% to over a million PPD
 
Thank you very much for your estimates and explanation.

I currently can buy 6128s for 75 euros a piece, 6136s for 95 euris a piece and 6172s for 185 euros a piece. I am seriously considering buying the 6136s (8 cores) and save up for the mobo which is about 750 euros (uuurghhh). In the future I can always go for a newer lineup of Opterons or 6100 12 cores.
 
i see that you 4p people have taken this teams production to a new high. :) even though stan and loudbob are yet to still construct more folding power you are all doing a very good job!

when you get your second intel 4p running loudb will you be turning off all your other cpus/gpus

Those are great prices, go for the 6172's if you can, they are 2.1Ghz and you may be able to squeeze a bit more performance out of them by overclocking. The 8 core aren't worth bothering with in my opinion.

I only went for the 6166HE's because the HE chips are low power and have the ability to up the voltage so I could get them to 6176 speed easily. That was a long time ago now when all the chips were much more expensive.

If you can get ES (or extra spicey) chips then they will be unlocked multipliers and they clock even better.

My 6272 are spicey and currently at 3.1Ghz is pushing 720K PPD on an 8103

But as you note the motherboards are the expensive part look for the H8QGI+-F as that tends to be the cheapest.

Which ones have an unlocked multiplyer? Only specific Engineering Samples?

And voltage unlocked? Is that for only a specific type?

I know they said best offer. But I don't want to insult you by going for prices lower than what I can get them for over here. I have a buildlog going on here and I enjoy having a chat with you guys. I don't feel like causing a fuzz trying to get the best stuff for the lowest price. Of course I want to build a 4P folding rig with the highest output for the lowest price possible. But don't feel like doing silly offers that will offend anyone.

Unlocked multi yes only ES or Engineering Samples.

Voltage unlocked ES and HE's

looks as if techpowerup will be back ahead again soon if they keep up what ever it is they are doing, unless its just for the chimp challange thing i don't know, either way they have sure starting doing well!

Thats the thing about the CC, often people join other teams to help them so it artificially inflates their stats while its on.
 
woah my 6272 @ 3.1Ghz is pushing 731K PPD on a P8104 :eek:

I know these puppies can get to 3.6, maybe I should throw a beefier PSU in there and see what shes got :D
