I currently have two 8800GT's running, not in SLI. In the stderr.txt, I see the shader speed for device 0 is listed as 810, whereas the device 1 is listed at 1512. Any reason why this would be? I checked Everest and it reports one 8800GT running at reduced core, shader, and memory speeds (400 core vs. 600 stock, 810 shader vs 1500 stock, and 499 memory vs 900 stock). Any ideas? The "slow" card is a PNY Verto GeForce 8800 GT, running in one of 3 x16 pci-e slots on my motherboard (the primary slot with my monitor connected is the card running at normal speeds).

Any ideas?

I'd also guess power saving. You know how to get it back to full speed?

No, I am not sure how to get it back running at stock speeds. However, looking back at the stderr.txt files, it appears it was always running like this.

Yes ... the same problem has a member from our Team.

My hind to this problem is BIOS update with nvflash with the Gridtested stable settings.

OK, if you want to go for the flash I suggest the following: take the primary card out, maybe place the second one in the primary slot (may not matter, though) and then:

- take a look at what speeds this secondary card runs after you boot windows
- if it's stock clocks, run some stability test.. maybe a 3D Mark for a 1 hour loop
- if everything is fine your card should be fine and you can flash

If there is any hardware reason, which we're not aware of (e.g. reduced voltage), why it doesn't run normal stock speeds, then flashing its bios could render the card useless, because you couldn't boot with it to flash it back. There's no reason to take that risk ;)

I also flashed the BIOS of my 8800GTS, its quite easy... The biggest problem is to prepare a bootable medium, if you don't have a USB flash drive or floppy to hand ;-)

In case you flash the wrong BIOS, you can use an old PCI video card to start the system and flash back the original BIOS, that you saved before.

My 9800GT had the problem that it was running at 600MHz core, 1512MHz shaders but only 500MHz on the memory. I fixed that (under Linux) by inserting

options nvidia NVreg_DeviceFileUID=0 NVreg_DeviceFileGID=44 NVreg_DeviceFileMode=0660
options nvidia NVreg_RegistryDwords="PerfLevelSrc=0x2222"
options nvidia NVreg_Mobile=1

I had the same problem with my 2 8800GT's.
The 2nd 8800GT would run at 400/810/500 (instead of 600/1500/900)
That only started after I installed the 177.67 drivers :(

If I un-installed the drivers, rebooted, re-installed, rebooted then both cards would run at their normal speeds, however upon next reboot the 2nd card would run at 400/810/500.

Going back to the older CUDA1 beta drivers and the 2nd card did not have that problem, however you can't run ps3grid with them :(

I ended up putting the 2nd card in another machine.
I have not tried again since I am now using Vista (with 177.92 drivers), and have only 1 monitor (great idea Microsoft!)

It seems to be a driver problem.
My 8800GT's are different speeds, and even the factory OC one got down clocked to 400/810/500 (from 700/1700/1000), when I tried swapping the cards about.

Please check if forcing the highest powermizer settings helps...

Ok, this may help, but let me Preface my post:

I have almost zero experience with the GPUGRID/Boinc deal (I run WCG/Boinc). I have it setup and running as of ~1-2hrs ago. But I do have plenty of experience with the F@H GPU2 client and running multiple GPUs on the same rig. That said:

If You are running Vista (32 or 64) OR XP SP3....then you probably need to extend the desktop to each card.
A) Extend the Desktop in Display Properties after You "attach a Monitor to each card"--There are 3 ways to do this:

1) Attach a monitor to each card.
2) Your TV set may very well be accepted as a Monitor.
3) Use a VGA to DVI Dummy--here's a link: DVI to VGA Dummy.....56K! The dremel and all that is not necessary. Read through the post, if ya like. Just insert the resistors into the proper holes and attach to the card, then reboot and Vista/XP SP3 will detect it as a non-pnp monitor.

In F@H GPU2 config there is an option to set the GPU priority slighty higher--in F@H that will fix the unequal speed issue. Also, the same issue in F@H GPU2 was GPU -0 running slower (~50%) then GPU -1....as I'm seeing here. I haven't seen any setting(s) like that with the Boinc/GPUGRID, but it may help to set it in Task Manager.

HTH

with BOINC's current design, all task in windows run with a priority of 1, the lowest. There isnt any way to change that as far as I know, other than to manually change it in the task mamager.
