**Loony** · 10-14-2008, 02:34 PM

Hrmm...I got the increase now!

**MikeB12** · 10-14-2008, 02:35 PM

yes xgun... just stop the client and delete fahcore_11 from that dir in your profile. the folder you had to unhide.. and restart the client, it will dl a new core.

**xguntherc** · 10-14-2008, 02:37 PM

I have 1.13 will 1.15 help me out?

nvm.. did what you said.. already got 1.15 We'll see how it goes.

Thanks!

**Rise** · 10-14-2008, 02:39 PM

hmmm. I would have expected more... but maybe diff OS, or maybe it scales with OC? BTW... why isn't it overclocked!

**MikeB12** · 10-14-2008, 02:51 PM

BTW: yall might want to clear your fahmon data.
I clear mine all the time so old readings dont play with the numbers.

just stop fahmon and delete this file. it'll wipe the old info.

Perfect timing reading this thread, 8800gt just finished a WU, thanks

Last time I tried to bump up the shaders, the PC was crashing. I don't know why, but maybe RT? I need to use the EVGA tuner and try again.

**Sparky** · 10-14-2008, 06:46 PM

On the 8800GT with shaders at 1728 I went from about 5100 to 5600, boost of 500. 9600GSO at 1836 shaders went from 4900 to 5300, boost of 400. Just some round numbers.

**Polizei** · 10-14-2008, 07:51 PM

You can get the shaders higher on that 8800gt Sparks... I had them at 1783 no problem. It would do 5300ppd all day, so raising those will get you another 200ppd.

**road-runner** · 10-14-2008, 07:53 PM

Yea I am running 2-gts @ 725/1901/776...

Perhaps. Heard the new core puts a little more stress on the shaders so some have had to drop clocks down a notch. I'll try upping it when I have time to monitor it and make sure nothing goes unstable.

**[XC] hipno650** · 10-14-2008, 08:34 PM

well i got the new cores on both of my 8800gtx's and they seem to be working fine. now my question is about F@H mon what is it and were do you get it

Google turned up no DL's maybe in just crazy.

thanks

Awesome Mike, that's a really nice find, thanks for posting!!

My 9600GSO running 177.81 with CSM 648/1890/800 (same as on 1.09):

Project: 5800 (Run 4, Clone 136, Gen 3)
Fah core PPD 1.09: 4840
Fah core PPD 1.15: 5250
PPD increase on this project: 7.8%

Frame time 1.09: 85s
Frame time 1.15: 80s

Awesome change for "just" a core update!

Edit: the sound while folding is now several pitches higher than before. Also core temp increased by a healthy 4°C. It's nice to have a more optimised core to utilise the shaders better!

Edit 2: Wow, now it's 5316.9... o_0;

**DrJay** · 10-15-2008, 12:56 AM

Times decreased from 1m14s to 1m7s on Asus 9800gt UL. No clock speed changes.

**DAK1640** · 10-15-2008, 01:34 AM

Ver 1.09 is still the latest right?

**p2501** · 10-15-2008, 01:39 AM

No it isn't. It's officially 1.15 now, follow Mike's short how-to in the OP and enjoy a free PPD increase!

**DAK1640** · 10-15-2008, 01:46 AM

TY...I must live in a cave or something. Will I lose any WU's that are in process ?

No. I updated 64% in and the WU completed without problems.

Maybe your OC will be unstable with the increased load, I just know mine isn't unstable as it seems..

**MikeB12** · 10-15-2008, 02:08 AM

DAK,
my 8800gt/9800gt used to be stable at 1836 with core 1.09, it's not with core 1.15--- tried just for grins.
I always ran mine at 1783 anyway for stability reasons.. so no change in oc for me, but I tried 1836 just to see if I could like I did on the old core and it went eue unstable before wu finished at a paltry 60c. so it wasn't temps, it was the increased load and stock voltage causing it. they picked up about 4-500 ppd though on the new core.

**DAK1640** · 10-15-2008, 02:10 AM

Holy Geez Batman (p2501), this is great !!! TY for the help.

You're welcome!

But just to remember, Mike came up with/noticed this.

**MikeB12** · 10-15-2008, 02:25 AM

LOL! stanford and their gpu guru's came up with this... I just blindly stumbled onto it yesterday trying the console client out..

**MikeB12** · 10-15-2008, 02:37 AM

also just noticed fah has related threads for ati and nvidia cores, so i added these to the OP.

NEW CORE RESPONSIBLE FOR PPD INCREASE...
1. just stop the client and delete your current fahcore_11 (old core)
2. restart the client to dl a new fahcore_11 (ver 1.15 for nvidia or 1.17 for ati) automatically.
(read replies and linked fah threads for full story)
nvidia core 1.15 http://foldingforum.org/viewtopic.php?f=52&t=6203
ati core 1.17 http://foldingforum.org/viewtopic.php?f=51&t=6199
