Expected PPD?

[SavageCupcake]

Hi guys . I recently started folding again as I saw that f@h now makes better use of AMD cards on a few websites. I downloaded the latest version off the website but im still getting pretty low PPD ( between 6k and 7k :/. I'm running a 2500k @ 4.4ghz and a 7870 hawk edition. Is this still the expected amount for this or am I doing something wrong??

Is that 6k ~ 7k for both the CPU and the GPU? How long have you been folding
for (again)? I remember that you need to be folding for a certain amount of
time and need to turn in ~80% of your units during that period of time within
a certain time frame (I am presuming you do have your key which you need to
get fat PPDs). At least that was the case last time I checked.

I used to get ~13k PPD for my 2500 (@ stock, obviously). That was until last
September when I upgraded to 2600k which netted me ~20k PPD on stock and
~27k PPD @ 4.4 GHz.

Yep thats for both. It's gone up to 13k now as i finished one just after i posted this (It's worth 8k but will take over a day). Been folding for a few days now. not 24/7 just when i'm not playing games and doing college work (most of the time). What key would you be talking about here??

Basically you need a passkey to get bonus points, and you need to have been
folding for a little while and have returned a certain percentage of the WUs
in that time rather quickly. In rough terms.

For more info:

Read about the passkey here, and you can get one here.

I also suggest reading the section "Bonus Points" on this page.

EDIT:
To clarify: You need to have been folding with the passkey for a while
in order to get fat bonus points. So if you don't have one yet you won't
have received fat boni.

 

[SavageCupcake]

Right I just got myself a passkey. I'll leave it running when i'm at college tomorrow and see if it improves

 

[alpenwasser]

I think it usually takes a few days to ramp up to its full potential, even on 24/7,
so I wouldn't expect immediate point spikes. But you're on the right path; if you're
still getting low PPD after 10 days or so then I'd start to investigate further.

So long,
-aw

EDIT: Make sure you actually put the passkey into your configuration for the
folding client! Ordering it alone ain't gonna do it. :lol:

I'm not that much of a n00b

 

[alpenwasser]

Haha, I didn't think so, but I would feel rather bad if you forgot (for whichever
reason) and I'd forgotten to mention it. :banghead:

It's the little things :lol:

Ok I will address one thing at a time.

First of all the CPU folding in your case should be in the 8k to 10k neighborhood. Maybe 13k if the 2500k is overclocked really that high.

The 7870 could produce a lot more. Especially with the new beta-testing on openGL done right now. For it to work though you have to do a couple of things which might not be worth the effort, if this is meant to be a part-time folder...

You need to install the CCC 13.1 driver. During the installation you have to deactivate the installation of SDK (2.x I don't remember which version it will suggest). After the driver is installed, you have to download SDK 2.7 from the AMD homepage and install that. For some odd reason it won't work if you just update SDK. Without these steps your GPU will be only under 40% load. After this is setup right, it should be load in the high 90s. You can check with GPUz.

With some luck this ought to be everything and the GPU should be pushing in the 30k PPD neighborhood. Maybe a bit less...

 

[SavageCupcake]

Gpu usage used to be around 40% when I folded ages ago which is why i stopped. I'm running 13.3 beta and its using 80-90% of the gpu now though I didn't install the SDK like you said to.

Wow!

That's quite a bit less since I last folded on my 2500 (non-k, so stock clocks)
last September. I used to very reliably get ~13k PPD from around March 2011
through Dec 2012.

Things seem to have changed a bit it would appear :huh:

 

[mihapiha]

Because the WUs keep changing the PPD values go up and down. I mean I've seen on my folding farm everything from 400k PPD to 670k PPD which is quite a massive difference if you think about it...

Oh yes absolutely, I've had that as well. My 2600k got between 18k PPD and
35k PPD, so... yeah

I'm just talking about the averages I got over those 18 or so months. I took all
the points I made and divided them by the number of days. Came out to ~ 13k
PPD on average. And my 2600k got ~27k PPD from last September to this March,
which was when I switched to BOINC (reasons here.).

Apologies if this is going a bit off topic.

But is 50+k PPD on an overclocked 3820 (4.2ghz)+ a stock GTX 560 high or normal??

Seems like a huge difference over chips like the 2500/600k?

I know my sig says less then 50k but I'm not running my rig 24/7 at full.

just trying to get a grasp on what is 'normal'

I've been able to found little info on this. But considering that both the 2600k
and the 3820 are Sandy Bridge Architecture, 4 cores with hyperthreading I'd
say that they should produce around the same results, unless the quad memory
architecture on the 3820 is somehow extremely advantageous for F@H.
So, something between 20k PPD and 35k PPD for the 3820 if results are similar
to the 2600k; depending on project and clock speed (those are the lower and
upper boundaries for my PPDs with the 2600k, ranging from stock speed to
~4.4 GHz).

As for the 560, two years ago, it appears to have gotten around ~14k to 15k PPD,
according to this. Since these numbers change over time, I'm not sure how
valid those benches are anymore.

Bit-Tech seem to have achieved around 13k PPD for a Ti version, as a side note.
Again, not the most current data though.


EDIT: To answer your actual question: From my personal experiences
with the 2600k and looking at what little data there is, 50k PPD for your
combo seems pretty good. On average I got 27k PPD out of my 2600k when
overclocked (see above), so I would expect your setup to do somewhere
around 40k PPD on those clocks. But that's just conjecture

Alpenwasser, doing some investigating here. Looks like my 560TI alone is fetching a maximum of 20+k ppd! Wasn't expecting that at all.

The 3820 @ 4.2ghz is doing around 30kppd alone. The combined PPD is sitting around 50k at the moment. Im curious to see what a 4.6ghz overclock would do Should I try??!

These figures seem to vary day to day though depending on the work unit Im doing.

The difference must be in the 2011 architecture ?

Additional info for those interested.

2011 architecture does help in term of quad channel memory

although i wouldnt really push your overclock any higher, what you need to remember F@H stresses your system in no way youve ever seen before, what might be 24/7 OCCT/Prime95 stable, may not be F@H stable

Your PPD will vary alot depending on the workunit as some units are finished in a hour, some take 6, more time spent means less PPD

Well, in that case, take the points, and run! :lol:

I recently read an article about running o/c'd CPU's on BOINC, in which they
were trying to discourage people from overclocking too highly. The problem
seems to be that an overclocked CPU (or GPU, for that matter) can produce
false results, yet still appear to run stably (meaning your system or
the program does not crash, it just chugs along turning out false results).

Since running something like F@H is extremely stressful for your CPU and
you won't get that much more points (I estimate), I'd probably not go too
high with the O/C. You can certainly try and do a bit of testing though .

Yes that has also been my experience.

It would appear to be the case. Good to know, I was not sure how much the
quad channel memory would benefit the PPD, but it appears to be rather
substantial

Although I have had periods where I got >30k PPD on my 2600k, and on
total average I got 27k PPD, which means (if you keep averaging 30k PPD)
that you have ~10% more PPD. That does not seem to be too unreasonable.

although i wouldnt really push your overclock any higher, what you need to remember F@H stresses your system in no way youve ever seen before, what might be 24/7 OCCT/Prime95 stable, may not be F@H stable

+1, see above.
