Need Multi-GPU Help......56K!

[Shadowtester]

A quick and dirty way to make a dummy plug is to just use the dvi to vga adapter and insert the resistors directly into the correct connection holes however its not a real good long term option since nothing except a little friction is holding the resistors and they are not protected from shorting out against each other if one get bent by accident a hooded db15 connector with the resistors soldered in is a much better long term option and not very expensive parts needed run around $5.00 at Radio Shack. Radio Shack does not have 75 ohm resistors but they do have 68 ohm resistors and they will work fine anything between 50 ohms and 150 ohms will work 75 ohms is just optimum.

Ok, not working and it makes things worse. I've seen this before, but it was 1x 8800GS OCed and 1 stock. Now its 1 @ stock and the other at Zero:





These are WCed and from the temps it looks like the Zero card is working and the stock card is not.....



I've extended the desktop to the 2nd monitor--physically. In Vista I extended it to "Monitor 4" and then "Monitor 3". Both show a display, but my folding rate goes to over 6 mins and the points drop to just over 1K/card. I rebooted each time. I am going to try "Monitor 2", but not expecting that to help.

I have the monitor plugs plugged into the Top DVI via a vga to DVI adapter. Does that matter? I would think not, but.... Also, I am using some Vga to DVI adapters that I already had--not the specific ones that came with the cards--again: Does that matter? I would think not, but...

Was hoping this was the ticket. What now?

Ok, strange, but progress:

I added the -gpu 0 and -gpu 1 via the configs. Now it seems that -gpu 0 is running @ ~3mins per % and -gpu 1 is running ~ 1 min 31 secs.

Progress: Yes. But what does it mean?

-gpu 1 is running 100%
-gpu 0 is running 50%

Got It!!! Another fluke, but whatever works--Works! I added the -gpu 0 and -gpu 1 to the config files and that brought 100% and 50%. I haven't been able to understand why I cannot get Rivaturner to recognize both cards and allow me to manipulate them independently...didn't make much sense.

So, I was fumbling around in RT--again--and decided to UNcheck:




That did it!!!! Now I can manipulate each card independently and they are both cranking 100% !!! Note: It is UNchecked by default. I checked it a few days ago thinking it would be a Good Thing.





I believe the temp difference is because I have the flow going into 1 card then the other--and---I believe--its hitting the cpu before it gets to the cards. I may swap things around later--but that's the E-A-S-Y part!

I swapped the 2nd monitor back to its original pc. Didn't change anything on the cruncher. Not sure what's going to happen whenever I reboot it, but I guess I'll find out the next time. Worst comes to worst--I'll hook up the 2nd monitor, get things going and then swap it back until I can get a vga dummy made.

So, now things look like this:

GPU1:



GPU2:




Man, I'm a Happy Camper right now!


Thanx Everybody for Your help! Its good to know that You guys are there! Hopefully this will save someone else some headaches.
