Here is the only p114X I've had complete thus far;

iMac G5 1.8GHz, OS X 10.4, and 1GB Dual Channel RAM

Index 6: finished 600.00 pts (7.479 pt/hr) 24.5 X min speed
  server: 171.65.103.156:8080; project: 1140
  Folding: run 6, clone 42, generation 4

I've had 4 or 5 others on my PM G5 Dual 2.5, but they have all EUE'd with the appropriate credit issued for time spent.  For instance, one EUE'd at 92% and I received 553.7 pts.

This is a fascinating WU to open up in the the FPD viewer, yes it is a complicated looking thing. Hope the stability issues come to a resolve.

Looking good so far...

Using "experimental flags" or what I would call non "experimental flags" or rather lack of flags, other than yes on the Big WU.

And this may be a temporary place to be, but it suite me just fine at the moment.

Then it only gets yummier, off to project: 1323.

folding now 308.00 pts (10.732 pt/hr) 27.6 X min speed; 10% complete.

As for my G4 1.2 Ghz, it will be chugging away for 5 days on this one WU, if all goes well. So these are not for the impatient.

May the folding karma be with you!

I changed the ~advmethods flag (didn't have big WU's selected anyway) to off on two machines, an 800 mhz eMac and a 1.42 mini.  The mini pulled a p2000 and the eMac pulled a p2002.  They don't list how many points they're worth, though a look at the project site tells me they're worth 154 and 180 respectively.  My eMac queue reads:

I'm assuming that I'm right in figuring out the point values.  I was a bit nervous when no point values showed up anyplace in InCrease.

Anyone else run into this?

[Macaholic]

Head for Tools in the menubar.  Download qd updates.  Your points should register correctly after a step or two.

[treadlightly]

Ah, thanks!!  I had to quit and restart InCrease (note, I didn't stop and start) and the points appeared.  I even had them correct to boot!

[treadlightly]

CB, another question.  On your initial page, you mention 5mb ON for G5's.  Would that go for an iMac G5 with 512 mb ram?  I thought (probably incorrectly) that the 5mb ON would really only be effective with more ram than that.

[Macaholic]

Yes.  Even with only 512MB RAM you should be fine.  My iMac G5 has 1GB and 5MB ON and I still get saddled with Tinkers, a Regular Gromac, or sometimes a p132X (5MB Gromac).  G5s can handle the Tinkers about the same or better than a Regular Gromac.

Index 8: finished 302.00 pts (9.180 pt/hr) 24.1 X min speed; project: 1322 5MB Gromac

Index 9: finished 57.00 pts (3.143 pt/hr) 23.8 X min speed; project: 1591 Regular Gromac

Index 1: finished 241.00 pts (4.223 pt/hr) 28.6 X min speed; project: 1138 Tinker

[treadlightly]

Definitely a BIG improvement.  My pph went from 2.7 to 3.7 with the introduction of Tinkers.  Very nice!

Macaholic i've gotta say your a bit off with some of your intel/amd configs. the flags are alright but the 5MB option isnt. It really doesnt have to do with the CPU as much as it does with the amount of memory as well as configuration. I've been working on this for a while and I suppose I'll share my conclusions with you. If you have an Intel/AMD processor and 256MB of RAM of less then you should NOT under any circumstance run the large WU option. However if you have 384MB(265+128) then it depends on what OS your using. Any kind of *nix will be OK. Windows 95, 98, 98SE, 2000/nt will all be OK. However with XP pro and Home its right on the borderline. If you can install a stripped down version of home/pro and run NO apps on it other then folding then 384MB will usually (if windows isnt updating or BSing) suffice. However If you plan on actually making XP usefull and functional then 512MB is the minimum needed to run the large WU tag. But, even with 512 you'll find that you frequently run out of memory and start using your slow hard drive pagefile. But with DDR400 being so cheap right now theres no reason that 512MB or even 1GB should be out of anyone's reach. Also with the Large WU's enabled dual channel memory does offer an ever so slight performance boost.

And while on the topic of memory might as well talk about FSB(Front Side Bus). If possable always go for the higher FSB processor. For intel try to get an 800mhz processor instead of 533mhz. The extra bandwidth helps on QMD's, Ambers and DoubleGromacs(which are almost extinct). For athlon 64 the FSB matters not. But for athlon xp's or mp's or durons the same applies for FSB. Higher always helps.

Now If you have a P4 that has HT enabled(Hyper Threading) then you can run two instances of F@H at once to increase your production! Macaholic has already covered this and evidently knows that recieving two QMD's often fugs up your processor and will cause early termination and only gets you 5 points.

I hope this helped, if you have more questions about folding on a Intel/AMD processor stop by our folding forum here: http://maximumpc.com/forum/viewforum.php?f=32
