Yeah I think Billy's made a mistake somewhere as I get a silly number for ppd if I use that formula :confused:

Grr. I'll get it right one of these days.

(time per frame in minutes * 100 frames per WU) = minutes per WU
(Minutes per WU / 1400 minutes per day) = days per WU
(Points per WU / days per WU) = points per day

so a bit of substituting yields

Points per day = (Points per WU / ((time per frame in minutes * 100 frames per WU) / 1400 minutes per day))

For Rich's benchmark:
376 / ((42.8166667 * 100) / 1 400) = 122.942779

I have no idea where FahMon's other 4 ppd are coming from. Maybe rounding errors? :confused:
 
Or a little more friendly looking...

PPD = (Points per WU x 14) / Time per Frame in Mins

yup FahMon seems to have given extra points, like you say it is probably a rounding error somewhere - though being out by 4 is quite some error :o

I got the same as you when I worked it out btw so it has to be something FahMon has done
edit: I'm still using FahMon v1.8.1 so it may be something that has been fixed in the new version - have put off upgrading as I wanted to keep my benchmarks but I will probably put the new one on when I get my rigs sorted out :)

Aren't the benchmarks kept in a text file somewhere that you can keep when you upgrade?

I'm pretty sure I read that v2 uses a different way of storing them and the two aren't interchangeable

It's no bother really - I can keep both versions and just run the old one when I want to check an old benchmark. I was only really keeping it for when we were running a benchmark site a long while back which has since been put on a very very slow back burner :p
 
i think I may have just assumed it wasn't possible due to this in the program revision history...

v2.0.0 (24/09/05)

* FahMon has been entirely rewritten and now works also with Linux. A lot of changes have been done, just check them! (Beware that file formats have changed and are not compatible with previous ones!)

Ask them to put an 'export benchmarks' in the next version. You can copy and paste them all but its a lot of hassle.
I wouldn't mind an integrated vnc client aswell while they're on...
 
Im using FahMon 2.1.0c here. Everything seems to be ok. No problems. Dont really need to change if a new version comes out.

Anyway, this rig had some time on its own with F@H last night. New info.

Wish that it stayed like this when I was using the rig too :(

I think you'll find the extra 4 ppd comes from the fact there's 1,440 minutes in a day, not 1,400 as you've put in your formula :P

ahhh now that's more like it....

after being stuck with some rubbish Gromacs WUs for the last couple of days I finally got something which the X2 likes :D
Just a shame they are only short WUs :o
not bad PPD though since there are no bonus points on these AFAIK

that's still at stock so can't wait to see what a bit of speeding-uppage will do :)
 
I've swapped my trusty XP2500@3200 for a shiny new opty 146 then cranked it up to 2750Mhz and all i'm getting is a measly...

There's some better ram arriving soon that might improve things though.

yeah there are some really terrible Gromacs WUs around at the moment :(


you should think about joining the beta team - my beta rig (currently an overclocked XP1700) has got nothing but DGros for weeks now, it doesn't like them anything like as much as the X2 does but they are still better points than the Gros
