I am thinking about an upgrade and if the factory OCing worked with E@H or it had to be dialed back?

Anyone running a Gigabyte GV-N770OC-2GD on E@H

This request is far too specific to expect the answer you're looking for. But these high end GK104 card's aren't all that different and the maximum boost clock of the Gigabyte of 1.19 GHz isn't unheard of. Actually my 1.5 years old GTX660Ti (KFA²) boosts to the same clock, can take another 50 MHz on top of that at a lower maximum voltage than GTX770 is allowed to use. And Einstein isn't that demanding / restrictive regarding GPU clocks (compared to GPU-Grid, which I used to determine this clock speed).

So I say it's very probably a safe bet. I certainly wouldn't worry about it not working.

Thanx for the input MrS. I

Thanx for the input MrS. I pulled the trigger today and ordered it. I was lucky enough to pick up the 4g version for a few bucks less then the regular cost of the 2g version not a big factor here but why not. I figure with what I've read about this card elsewhere with the oc room left on this card It will perform as well or slightly better than a GTX680 but at a lower price point. It will certainly be an improvement over the lackluster performance of my 650ti. Also upgrading case fans for better cooling capacity. I'm now in the panting at the door stage waiting for it! I will come back after upgrade is completed.

OK. New card is in and

OK. New card is in and running great. Now I could use some real help. I put the new card in slot 0 and put the 650ti in 1. From what I read in order to run both I need a config file to tell BOINC to use all gpu and also to tell it to use a gpu utilization factor of .33 for the 650ti(I have the E@H set at .25 bcause the 770 can handle it but the 650ti can not). I don't know how to write it or where to place it. I have seen this type of thing on the boards b4 but can not find at the moment. Any help would be great. Also is it possible to make the gpu utilization factor for the 650ti only apply to E@H as I am thinking of maybe running gpugrid now and then.

Create a text file called

Create a text file called "cc_config.xml" and put it into your BOINC data directory. Be careful with windows editor, as it will by default create "cc_config.xml.txt", which won't work. Switch to "show all folders" to avoid / correct this or use some other editor. Or maybe copy some real .xml file instead of creating a new one. Then just overwrite the current contents.

Place in there the following contents to get both GPUs working:

1

You can't set the utilization factor per GPU. The easiest would be to run 3 WUs on each GPU. Would the GTX770 suffer a throughput hit from this? It wouldn't be much, I assume.

The utilization factor only applies to E@H, so no problem to run GPU-Grid as well. If you do so I'd only use the GTX770 over there, as GPU-Grid scales very well (i.e. can actually use the faster GPU) and the faster GPu will have no troubles returning long-run queue tasks within 24h to get the bonus credits. The smaller card is better at E@H, as it scales "OK" with GPU power, i.e. you wouldn't gain as much from faster cards here. There's another config file which you could create to statically allocate GPUs to different projects. Then you wouldn't have any problems with the utilization factor :)

Thanx MrS. Please go ahead

Thanx MrS. Please go ahead and give me the other config file to statically allocate GPUs to different projects. I will try that as well later.

THANX,Robert

Okay MrS I must admit I am

Okay MrS I must admit I am not as smart in this area as I would like to be. I switched to show hidden files. Went into program data, then opened boinc, then right clicked hit new, named as stated, cut-paste the config lines. But the new file shows as a text doc not as a .xml and of course did not work. What did I screw up? I feel like a lunk. Thanx for your patience.

Go to the Windows Explorer

Go to the Windows Explorer Options again, this time to deselect "Hide extensions for known file types".

Windows by default hides known extensions, as it prefers to show assiciated file type icons instead of file extensions for ease of purpose and to prevent users from accidentally changing or deleting file extensions - Windows needs those to know what File is to be accessed with which program. Convinient, but sometimes you just need to access the file extensions.

Then your file will show up as what it likely actually is right now : cc_config.xml.txt
(when you created the file, you created a windows text file which is automatically given the .txt file extension regardless of any extension you gave it yourself in the filename)

Manually rename the file to cc_config.xml, which will prompt a Windows Caution message, as you're about to change the file association from .txt to .xml ...

After you confirmed your choice to rename, things will work as expected, as you now have a true .xml file that BOINC recognizes :)

Windows File Assiciation principles (funny) didn't really change since the inception of Windows 2.0 :p ... basically still relying on that part of the MS-DOS 8+3 Characters (8 chars filename + 3 chars extension) filename scheme after all these years.

(remember while working in any BOINC Directory, BOINC needs to be stopped (Quit), as it only checks the file during its launch)

Sorry, my bad! "Show all

Sorry, my bad! "Show all folders/files" has nothing to do with this.. should have typed more consciously. Anyway, glad it works now!

About the static GPU-project assignment: I'm actually not using this myself. I'll try to look it up over the weekend if noone else beats me to it.

THANX ETA whenever you get

THANX ETA whenever you get the time. I appreciate all the help. I am still playing with settings. The 650ti is being fussy all of a sudden. 3x and it crashed I am switching to 2x and hoping the speed of the 770 will pick up the slack on rac. As I just gave away my WIN8 box to my sister whos 12+ year old box died and am trying to see if I can bring it back to life and get it running for E@H with a 640 I have spare. Not fast but steady. Heck if the 650ti stays twitchy I might as well switch it out with the 640 at least I know it can do 3x and produce 16k-17k rac/day steady.
